Emhlabeni wezokwakha zesimanje zikakhonkolo, igama elithi "post tensioning" seliyefana namandla, ukuqina, kanye nokuguquguquka komklamo. I-post tensioning iyindlela lapho izintambo zensimbi ezinamandla aphezulu ziqiniswa ngemva kokuba ukhonkolo usubekiwe futhi womile, kusetshenziswa ingcindezi yokucindezela ukhonkolo ukuze kulwiswe namandla okudonsa. Ikhwalithi yezinto ezisetshenziswa kule nqubo—ama-grouts, ama-anchor, izintambo, kanye nezinto zokugqoka—inquma ngqo ukusebenza kwesikhathi eside nokuphepha kwesakhiwo. Lapho izinto zehluleka, ukulungisa kuyabiza futhi ngokuvamile kuyahlasela. Yingakho onjiniyela nosonkontileka kufanele babeke phambili ukukhethwa kwezinto, befuna izixazululo ezibhekana nokugqwala, ukuqhekeka, kanye nokwehluleka kwezintambo ngqo. I-Dezhou Zhongke New Materials Co., Ltd., eyaziwa embonini ngokuthi i-德州中科, inikeza uhla oluphelele lwezinto zokwakha ezinamandla aphezulu ze-post tensioning ezenzelwe ukuhlangabezana nezimo ezinzima kakhulu zokwakha. Lo mbhalo uhlola indima ebalulekile yekhwalithi yezinto, izinselele ezivamile ezibhekana ne-post tensioning, nokuthi imikhiqizo emisha ye-德州中科 iletha kanjani izixazululo ezinokwethenjelwa, ezingabizi kakhulu kuma-slabs, amabhuloho, nezakhiwo zokupaka.

Ngisho noma i-post tension slab yakhiwe kahle kakhulu ingaba nezinkinga ezinzima uma izinto ezisetshenzisiwe zingekho ezingeni. Ukugqwala kuyingozi enkulu kunazo zonke ezinhlelweni zokucindezela ngemuva. Lapho umswakama nama-chloride engena kukhonkolo futhi efinyelela ezintanjeni zensimbi, ukugqwala kwe-electrochemical kuyaqala, kunciphisa kancane kancane indawo enqamulelayo yentambo, okuholela ekuhlulekeni okungazelelwe, okuyinhlekelele. Lokhu kuvame kakhulu ezindaweni zokupaka izimoto, ezakhiweni zasolwandle, kanye namabhuloho achayeka kusawoti wokuncibilikisa iqhwa. Ukuqhekeka kukhonkolo ozungezile kungenye inkinga evamile, ngokuvamile okubangelwa ukugcotshwa okungafanele noma ukusetshenziswa kwe-grout engekho izinga efinyela noma ene-permeability ephezulu. Imifantu inikeza izindlela ezingenwa yizinto ezinobungozi ukuze zifinyelele ezintanjeni ze-post tension, zisheshise ukonakala. Ukuhluleka kwentambo, noma ngabe kubangelwa ukuqhekeka okubangelwa ukucindezeleka, i-hydrogen embrittlement, noma umonakalo womshini ngesikhathi sokufakwa, kumelela ingozi enkulu kakhulu—kungabeka engcupheni lonke uhlelo lwesakhiwo ngaphandle kwesixwayiso. Abakhi abaningi baphinde babhekane nokusebenza okungahambisani kwezinto, izinqubo ezinzima zokusebenza, kanye nokuntuleka kokwesekwa kwezobuchwepheshe okuvela kubathengisi. Lezi zinselelo zigcizelela isidingo somlingani othembekile onganikezeli nje kuphela imikhiqizo esezingeni eliphezulu kodwa futhi nesiqondiso sobunjiniyela kanye nokusekelwa endaweni kuyo yonke impilo yephrojekthi.

Ukuqonda umehluko phakathi kwezinhlelo ze-post tension ne-pre tension nakho kusiza ekubongeni izidingo zezinto zokwakha ze-post tensioning. Ku-pretensioning, ama-tendon aqiniswa ngaphambi kokuba ukhonkolo uthelwe, kuncike ekudluliselweni kwe-bond ngqo. Ku-post tensioning, ama-tendon aqiniswa ngemuva kokuba ukhonkolo uqinile, ngokuvamile afakwe emapayipini futhi avikelwe nge-grout. Lokhu kwenza i-grout, ama-anchor, nokuvikelwa ekugqwaleni kube okubaluleke kakhulu ku-post tensioning ngoba abukho ubudlelwano obuqhubekayo obuhamba ngobude bonke be-tendon. I-post tension slab incike ekuqineni kwalezi zingxenye ukuze isabalalise ingcindezi ngokulinganayo. Lapho ukugqwala kuqala noma izikhala ze-grout zakheka, umzila womthwalo uyaphazamiseka, okuholela ekucindezelekeni okugxile endaweni ethile nokuwa okungenzeka. Ukukhetha izinto zokwakha ezibhekana nalezi zindlela zokwehluleka akukona ukukhetha—kuyisidingo sobunjiniyela.

I-Texas Zhongke ithuthukise iqoqo eliphelele lemikhiqizo eklanyelwe ngqo ukunqoba ubungozi bokugqwala, ukuqhekeka, kanye nokwehluleka kwemisipha okungokwemvelo ezinhlelweni zokucindezela ngemva kokuqina. Enhliziyweni yesisombululo sabo kukhona i-grout esebenza kahle kakhulu eyakhiwe ngokungena kancane kanye namandla aphezulu okuminyana. Le grout igcwalisa ngokuphelele amashubhu azungeze izintambo zokucindezela ngemva kokuqina, idale umgoqo oqinile ongenakungena othintela umswakama nama-chloride ukuthi angafinyeleli ensimbi. Ngokungafani nama-grout avamile angashwabana futhi aqhekeze ngokuhamba kwesikhathi, i-grout yakwa-Texas Zhongke ikhombisa ukuzinza okuhle kwevolumu kanye nezici zokubopha, iqinisekise ukuvikelwa kwesikhathi eside ngisho nasezindaweni ezinobudlova. I-grout futhi inezici ezingcono zokugeleza, evumela ukungena emashubhini amancane nasezintamboni eziningi ngaphandle kwezikhala noma ukuhlukaniswa. Uma isetshenziswa ohlelweni lokucindezela ngemva kokuqina oluboshiwe, le grout ivimba izintambo endaweni yazo, inikeze ukudluliswa kwamandla okugcwele kanye nokuphindaphinda okungabikho ezinhlelweni ezingaboshiwe.

Ngaphezu kwe-grout yabo ethuthukisiwe, i-德州中科 ikhiqiza ama-anchor afakwe umhlanganiso anikeza ukuzivikela okwengeziwe ekugqwaleni endaweni esengozini kakhulu yohlelo—indawo yokugxila. Lawa ma-anchor aphathwa ngemifutho eqinile yokugqwayiza emelana nokugqwala, ukugqwala kwemifantu, kanye nokuhlaselwa kwe-galvanic. Ama-anchor aklanywe ngokunemba okunembile ukuqinisekisa ukuhlala okungaguquki kanye nokulahlekelwa okuncane kokungqubuzana ngesikhathi sokucinwa. Inkampani iphinde ihlinzeke ngezintambo ezifakwe emgodini kanye nezingcezu zokuguqula ezinhlelweni ezinamathela ngokuphelele, okudala indawo ephelele yokuvikela ukugqwala. Okuhlukanisa i-德州中科 indlela yabo ephelele: bahlinzeka nge-grout, ama-anchor, amapayipi, kanye nesiqondiso sobuchwepheshe ukuqinisekisa ukuthi yonke ingxenye isebenza ndawonye. Lesi sixazululo esihlanganisiwe sinciphisa ubungozi bokungahambisani kwezinto futhi kwenze kube lula ukuthengwa kukontraka. Ngokubhekana nezimbangela eziyisisekelo zokonakala—ukungena komswakama, ukuhlaselwa ngamakhemikhali, nokucindezeleka kwemishini—i-德州中科 isiza onjiniyela nabakhi ukuthi bakhiqize amaslabhu e-post tension ahlala isikhathi eside kunalawo akhiwe ngezinto ezijwayelekile.

Izinzuzo zomkhiqizo ezinikezwa yi-德州中科 zidlulela kude nokusebenza okuyisisekelo kwezinto ezibonakalayo. Isigaxa sabo esisebenza kahle kakhulu, isibonelo, sifinyelela amazinga aphansi kakhulu okungena kwamanzi okuvimbela ukungena kwe-chloride ion—into ebalulekile ezindaweni zasolwandle nasezifundeni ezisetshenziswa kakhulu usawoti wokuncibilikisa iqhwa. Ukuhlolwa kwaselabhorethri kanye nedatha yasensimini kukhombisa ukuthi isigaxa sase-德州中科 sihlala siqinile ngaphansi kwezimo eziphindaphindayo zokoma nokumanzi kanye nokubanda nokuncibilika, sidlula izigaxa ezijwayelekile ngezinga elikhulu. Lokhu kumelana nokugqwala okuphezulu kuhumushela ngqo empilweni ende yesevisi kanye nezindleko eziphansi zokulungisa kubanikazi. Uma ubala izindleko eziphelele zobunikazi be-post tension slab, ukonga okuvela ekugwemeni ukulungiswa ngaphambi kwesikhathi, ukushintshwa kwethenda, noma ukulungiswa kwesakhiwo kudlula kakhulu inani elikhokhelwa ekuqaleni lempahla.

Ukusebenza kalula kungenye yezimpawu ezivelele zemikhiqizo ye-德州中科. I-grout ihlinzekwa ngendlela exutshiwe ngaphambili, idinga kuphela ukwengezwa kwamanzi ahlanzekile nokuxutshwa ngomshini. Inesikhathi eside sokusebenza, okuvumela abasebenzi ukuthi baqedele imisebenzi yokugrouting ngaphandle kokuphuthuma, futhi ikhula ngamandla ngokushesha ukuze izinyathelo ezilandelayo zokwakha zingabambezeleki. Ama-anchor afakwe umhlanganiso afika nemiyalo ecacile yokufaka futhi angahlanganiswa nemishini ejwayelekile yokucindezela. Ezinhlelweni zokucindezela ngemva kokubopha, i-德州中科 ihlinzeka ngezinqubo ezinemininingwane zokugrouting kanye nokusekelwa kobuchwepheshe endaweni ukuze kuqinisekiswe umfutho wepompu ofanele, ukukhipha umoya, nokulawulwa kwekhwalithi. Lokhu kulula kunciphisa ubungozi bamaphutha okufaka, okuyimbangela ehamba phambili yezinkinga zokusebenza endaweni. Ngaphezu kwalokho, imikhiqizo ye-德州中科 inamanani ancintisanayo, okwenza ukucindezela ngemva kokubopha okusebenza kahle kakhulu kutholakale emisebenzini eminingi—kusukela ezakhiweni zezentengiselwano nezindawo zokupaka izimoto kuya emabhulohweni nasezikhungweni zezimboni. Ukuhlolwa okuqinile esigabeni ngasinye sokukhiqiza, kusukela ekuhlolweni kwezinto ezingavuthiwe kuya ekuqinisekisweni komkhiqizo ophelile, kuqinisekisa ukuvumelana phakathi kwezikhathi zokukhiqiza kanye nokuhambisana namazinga omhlaba wonke afana ne-ASTM kanye ne-EN.

Uma kuqhathaniswa izindlela ze-post tension ne-pre tension, izinzuzo zesikhathi eside zokusebenzisa izinto ezisezingeni eliphezulu ziba sobala nakakhulu. Izinto ezi-pre-tensioned zivame ukwenziwa endaweni yefekthri elawulwayo, kuyilapho i-post tensioning ivame ukwenziwa endaweni yomsebenzi lapho izimo zihluka khona. Ama-grout asezingeni eliphezulu nama-anchor afakwe i-德州中科 anqoba izinselelo zokufakwa endaweni, aqinisekise ukuthi uhlelo oluhlanganiswe endaweni lufinyelela amazinga okusebenza asondele kwezinto ezenziwe ngaphambili efekthri. Lokhu kwenza i-德州中科 ibe ukukhetha okuthandwayo kosonkontileka abadinga ukwethembeka ngaphandle kokudela ishejuli noma isabelomali.

Ukukhetha izinto ezifanele zokucinisa ngemva kokudonsa (post-tensioning) kuphrojekthi yakho kudinga ukuhlolwa okuphelele kokuchayeka emvelweni, izidingo zomthwalo, kanye nezindlela zokwakha. Ezindaweni ezinobungozi obukhulu njengezindawo ezingasogwini, izakhiwo zokupaka izimoto, noma amabhuloho aseduze kwezimboni zamakhemikhali, ukuvikelwa ekugqwaleni kufanele kube yinto oyibeka phambili. Cacisa ama-grout anokungena kwe-chloride okuphansi kakhulu (isibonelo, ngaphansi kuka-1000 coulombs ngokwe-ASTM C1202) kanye nama-anchor anezembozo ezinamandla zokulwa nokugqwala. Ezinhlelweni zokucinisa ngemva kokudonsa ezinamathiselwe (bonded post-tensioning systems), qinisekisa ukuthi i-grout inokugeleza okuphezulu, ukuchichima okuphansi, nokungashwabeni ngaphansi kwezimo zasensimini. Uma isakhiwo sizobhekana nemithwalo ephezulu ejikelezayo noma izingcindezi ezinamandla eziguquguqukayo, khetha ama-tendon nama-anchor anokusebenza okufakazelwe ekukhathaleni. Cabanga futhi ngokwakheka kukakhonkolo (concrete mix design) kanye nokujula kokumboza (cover depth)—izintambo zokucinisa ngemva kokudonsa zidinga ukumbozwa okwanele ukuze zinikeze ukuvikelwa okwengeziwe, futhi i-grout kufanele ihambisane ne-pH namakhemikhali kakhonkolo.

Izidingo zomthwalo ziphinde zinqume ukukhethwa kwezinto ezisetshenziswayo. Amapulangwe amade anezingqimba ezinde kanye nemishayo yokudlulisa umthwalo enzima idinga amandla amakhulu e-tendon kanye nama-anchor amakhulu. Sebenzisana nomhlinzeki onjenge-德州中科 onganikeza amashidi edatha yobuchwepheshe namathebula omthwalo ukuze uhambisane uhlelo nemingcele yakho yokuklama. Ungazibukeli izici zokufaka: ukulula kokuxuba i-grout, ukumpompa emazingeni okushisa asendaweni, kanye nesikhathi sokusebenza kubalulekile ekugcineni umkhiqizo usemsebenzini. Hlala ucela izitifiketi zezinto ezisetshenziswayo namasampula ngaphambi kokuthenga. Ukusebenzisana nomkhiqizi onikeza imikhiqizo ehlanganisiwe—ama-grout, ama-anchor, amapayipi, izinto zokugqoka—kwenza ukuthola izinto kube lula futhi kuqinisekise ukuhambisana kohlelo. Ekugcineni, cabanga ngezindleko eziphelele zobunikazi kunenani lokuqala lezinto ezisetshenziswayo. Ukutshala imali ezintweni eziphakeme ze-post tensioning ezivela ku-德州中科 kunciphisa izindleko zokulungisa esikhathini esizayo, kwandisa impilo yokusebenza, futhi kuthuthukisa inani eliphelele lesakhiwo. Ukuze uthole isiqondiso sochwepheshe esihambisana nephrojekthi yakho, xhumana nethimba lobuchwepheshe le-德州中科, elingakuncoma ukucaciswa kwezinto ezisetshenziswayo okuhamba phambili ngokusekelwe eminyakeni eminingi yamava ekuhlanganiseni ukhonkolo kanye nezinhlelo ze-post tensioning.

Iphrojekthi yakamuva enkulu yendawo yokupaka izimoto edolobheni elingasogwini lwaseShayina inikeza isibonelo esiqinisekile somhlaba wangempela sezinzuzo zezinto zokucindezela zangemuva ze-德州中科. Isakhiwo, indawo yokupaka izimoto eyakhiwe ngezitezi eziyisithupha enezindawo zokupaka ezingaphezu kuka-2,500, sasiklanywe ngesitofu sokucindezela sangemuva esinwebeka amamitha ayi-18 phakathi kwezinsika. Umnikazi wacacisa uhlelo lokucindezela oluhlanganisiwe ukuze kukhuliswe ukulawulwa kwemifantu nokuqina endaweni enosawoti oluningi olusolwandle. Usonkontileka wakhetha i-grout yokusebenza ephezulu kanye nama-anchor afakwe umhlophe we-德州中科 ngemuva kokuhlola abahlinzeki abaningi. Ngesikhathi sokwakha, i-grout yabonisa ukumpompa okuhle noma ngabe kushisa, igcwalisa amashubhu ayisicaba ngaphandle kwezikhala. Ama-anchor afakwe umhlophe ahlala kahle, futhi imisebenzi yokucindezela yaqhubeka ngaphandle kokushelela noma ukulahlekelwa kwesihlalo. Ukuhlolwa kwekhwalithi kwe-grout eqinile kwabonisa amandla okucindezela angaphezu kuka-50 MPa ezinsukwini ezingama-28 kanye nezilinganiso zokungena kwe-chloride ezingaphansi kuka-800 coulombs—okungaphakathi kwezinhloso zokuqina zephrojekthi.

Ngemva kweminyaka emibili isebenza, igaraji lokupaka izimoto alikaze libonise imifantu ebonakalayo ezingxenyeni zamapulangwe e-post tension, futhi izinzwa zokuqapha ukugqwala ezifakwe esakhiweni zibonisa ukuthi awekho amathambo asebenzayo emisipheni. Umnikazi wabika ukuthi konga izindleko ezinkulu uma kuqhathaniswa nomsebenzi wangaphambilini owawusebenzisa i-grout evamile nama-anchor angafakwanga, lapho imifantu emincane yavela phakathi nonyaka wokuqala futhi yadinga ukulungiswa nge-epoxy injection. Impumelelo yalo msebenzi iholele ekutheni usonkontileka aqinisekise ukusetshenziswa kwezinto zika-德州中科 kuyo yonke imisebenzi ye-post tensioning ezayo. Leli cala likhombisa ukuthi ukukhethwa kwezinto ngokucophelela—okuholwa ngumthengisi onobuchwepheshe obujulile—kungashintsha ukusebenza kwesikhathi eside kohlelo lwe-post tensioning. Emisebenzini efanayo, noma ngabe isezindaweni zasolwandle, ezindaweni ezibandayo, noma ezindaweni ezinokuzamazama komhlaba, i-德州中科 inikeza izixazululo eziqinisekisiwe ezisekelwe yimininingwane yasensimini nokusekelwa okuqhubekayo.

Ubuqotho banoma yiluphi uhlelo lokwelula ngemuva (post tensioning) luxhomeke ekhwalithini yezinto ezisetshenziswayo. Kusukela kugrouti esebenza kahle kakhulu evikela izintambo emswakameni, kuya kuma-anchor anamekwe ukumelana nokugqwala ezindaweni ezibalulekile zokuxhuma, yonke ingxenye kumele isebenze ngokuhambisana ukuze kuqinisekiswe ukuphepha kwesakhiwo nokuphila isikhathi eside. Njengoba izinselelo zokugqwala, ukuqhekeka, nokwehluleka kwezintambo ziqhubeka nokushayela isidingo sezixazululo ezingcono, i-德州中科 izinze njengozakwethu othembekile konjiniyela, osonkontileka, nabathuthukisi emhlabeni wonke. Imikhiqizo yabo ehlanganisiwe, ukulawulwa kwekhwalithi okuqinile, kanye nokusekelwa kwezobuchwepheshe okusebenzayo kubenza babe ukukhetha okuvelele emakethe yezingxube zikakhonkolo kanye nokwelula ngemuva. Ngokukhetha i-德州中科, awuthengi nje izinto—utshala imali ekuthembekeni, ekusebenzeni kahle, nasekuthuleni kwengqondo eminyakeni eminingi ezayo. Ukuze ufunde kabanzi ngohlu lwabo oluphelele lwemikhiqizo yokwelula ngemuva, hlola eyaboIMIKHIQIZO ikhasi, noma uxhumane nethimba labo ukuze uthole usizo olukhethekile. Hlala unolwazi ngezinto ezintsha zakamuva ngokuvakashela ikhasi labo le-Ukusekela noma uxhumane nethimba labo ukuze uthole usizo olukhethekile. Hlala unolwazi ngezinto ezintsha zakamuva ngokuvakashela ikhasi labo le-IZINDABA ikhasi, futhi uthole ifa namandla enkampani ekhasini elithi NGATHI ikhasi. Ukuze uthole umbono obanzi wobuchwepheshe be-德州中科 ekuhlanganiseni ukwakheka kukakhonkolo kanye nokuqinisa ngemva kokunwebeka, qala ku-IKHASI LASEKHAYA ikhasi. Xhumana nochwepheshe babo namuhla ukuze uthole izixazululo ezenziwe ngokwezidingo zakho kanye nokuhola kokuthenga okuhambisana nomsebenzi wakho olandelayo.

I-Post tensioning iyindlela yokwakha lapho izintambo zensimbi ezinamandla aphezulu ziqiniswa ngemva kokuqina kukakhonkolo, zifaka ingcindezi yokucindezela ukuze kuthuthukiswe ukusebenza kwesakhiwo. Ikhwalithi yezinto zokwakha ibalulekile ngoba izintambo, i-grout, nama-anchor kumele amelane nokugqwala, agcine ukubophana, futhi adlulisele amandla ngokuthembekile empilweni yonke yesakhiwo. Izinto zokwakha ezingezinhle zingaholela ekuhlulekeni ngaphambi kwesikhathi, ukulungiswa okubizayo, kanye nezingozi zokuphepha. Ukukhetha imikhiqizo esebenza kahle evela kumkhiqizi ohlonishwayo njenge-德州中科 kuqinisekisa ukuqina kwesikhathi eside nokuthula kwengqondo.

I-grout yokusebenza ephezulu yakwa-德州中科 yenziwe ngokungangeni kwamanzi okuphansi kakhulu, evimba umswakama nama-chloride ukuthi angafinyeleli ezintanjeni zensimbi. Iphinde ibe nokuzinza okuhle kakhulu kwevolumu, ivimbele ukuqhekeka okuncipha okungadala izindlela zokungena kwezinto ezinobungozi. Uketshezi oluphezulu lwe-grout luyivumela ukuthi igcwalise amashubhu ngokuphelele ezintanjeni zokuqinisa ngemuva kokucindezela, iqede izikhala lapho ukugqwala kungaqala khona. Lezi zakhiwo ndawonye zinikeza ukuvikelwa okuqinile okungasebenziyo ekugqwaleni kwe-electrochemical.

Ekunweni kwangaphambili, izintambo ziyadonswa ngaphambi kokuba kuthululwe ukhonkolo; ukubophana phakathi kukakhonkolo nensimbi kudlulisa amandla ngqo. Ekwenzeni ngemuva, izintambo ziyadonswa ngemuva kokuba ukhonkolo usulukhuni, ngokuvamile zifakwa emapayipini futhi zivikelwe ngogesi. Ukwenziwa ngemuva kuvumela izikhala ezinde, amapulangwe amancane, kanye nokuguquguquka ekwakheni endaweni. Izidingo zezinto ziyahluka kakhulu—ukwenziwa ngemuva kuncike kakhulu ekhwalithini yogesi, ama-anchor, nokuvikelwa ekugqwaleni ngoba izintambo azibophani ngokuqhubekayo ubude bazo bonke kuze kube yilapho ukugqwayiza sekuqediwe.

Izimpawu zokuqala zokugqwala ku-post tension slab zihlanganisa ukungcoliswa komhlabathi ngomhlwa ebusweni kakhonkolo, ukuqhekeka okuncane emigwaqweni yama-tendon, kanye nokuqhekeka noma ukuhlukaniswa ezindaweni zokugxila. Ezigabeni eziphakeme, ukwehluleka kwama-tendon kungenzeka, okuvame ukukhonjiswa ukuchezuka okungazelelwe, imisindo enkulu, noma ukukhathazeka okubonakalayo kukakhonkolo. Izincomo zokuhlola njalo nokuqapha ukugqwala ziyanconywa, ikakhulukazi ezindaweni ezinobungozi. Ukusebenzisa i-grout yekhwalithi ephezulu nama-anchor afakwe umhlwa avela e-德州中科 kunciphisa kakhulu ingozi yokuqala kokugqwala.

Emaphrojekthini asogwini, qala ngokubeka phambili izinto ezinokumelana nokugqwala okuphezulu. Cacisa i-grout enokungena kwe-chloride ngaphansi kwama-coulomb ayi-1000 nama-anchor anezembozo ezinamandla zokulwa nokugqwala. Sebenzisa uhlelo lokucindezela kwangemva oluhlanganisiwe olunemisipha embozwe ngokugcwele. Sebenza nomhlinzeki onjenge-德州中科 onikeza izixazululo ezihlanganisiwe nesiqondiso sochwepheshe. Futhi cabanga ngokumboza ukhonkolo okwengeziwe, ukhonkolo onesilinganiso esiphansi samanzi nesimende, nemininingwane efanele yokukhipha amanzi ukuze kuncishiswe ukuchayeka ku-chloride.

Yebo, i-德州中科 inikezela ngemikhiqizo eyenzelwe kokubili izinhlelo ze-bonded ne-unbonded post tensioning. Ezinhlelweni ze-bonded, bahlinzeka nge-grout esebenza kahle kakhulu, ama-anchor ahlanganisiwe, namapayipi aklanyelwe ukugoqa ngokugcwele izintambo. Ezinhlelweni ze-unbonded, bahlinzeka ngezintambo ezigcotshwe amafutha futhi zimbozwe ngezinto ezivimbela ukugqwala. Ithimba labo lobuchwepheshe lingakweluleka ngokuhleleka okungcono kakhulu ngokuya ngezidingo zephrojekthi, izimo zomthwalo, nokuchayeka emvelweni.

Imikhiqizo yakwa-德州中科 ihlolwa ngokuvumelana nezindinganiso zamazwe ngamazwe ezihlanganisa i-ASTM, EN, kanye ne-GB/T. I-grout yabo ihlolelwa amandla okucindezela, ukungangeni kwamanzi, ukufinyela, ukugeleza, nokopha. Ama-anchor ahlolelwa umthwalo wamandla angashintshi nowokukhathala, ukulahlekelwa kwesihlalo, nokumelana nokugqwala. Iqoqo ngalinye lokukhiqiza libhalwa phansi ngezitifiketi zokuhlaziya, okunikeza ukulandeleka okugcwele nesiqinisekiso sekhwalithi kozakwethu bonjiniyela.

Nakuba izindleko zokuqala zempahla nokufakwa kwe-post tensioning zingaba phezulu kunezinsimbi ezijwayelekile, izinzuzo zesikhathi eside zivame ukuholela ekwehleni kwezindleko zokuphatha. I-post tensioning ivumela amapulangwe amancane, izikhala ezinde, izinsika ezimbalwa, kanye nemithwalo encane yesisekelo, okonga izindleko zokwakha. Uma kusetshenziswa izinto ezisezingeni eliphezulu njengalezo ezivela e-德州中科, izindleko zokulungisa nokugcina ziyancishiswa, okwenza i-post tensioning ibe ukukhetha okunezindleko eziphansi empilweni yonke yesakhiwo.

Izinhlelo zokucindezela ngemuva kokubopha, lapho izintambo zifakwa emhubheni, zinikeza ukusebenza okuphezulu ngoba ukudluliswa kwamandla kusatshalaliswa kuyo yonke ubude. Uma intambo iphuka, amandla aphinde asatshalaliswa ezintambweni eziseduze, kunciphisa ingozi yokuwa. Izinhlelo ezingabophekile kulula ukuzihlola nokuzishintsha ngazinye kodwa zinokusebenza okuphansi. Izinhlelo ezibophekile zidinga ukufakwa ngokucophelela kodwa zinikeza ukuvikelwa okuhle kakhulu ekugqwaleni nokuqina kwesikhathi eside. Izixazululo zokubopha zase-Dezhou Zhongke zenzelwe ukwenza lula ukufaka nokuqinisekisa ukufakwa okuphelele, kunciphisa izidingo zokunakekela ngokuhamba kwesikhathi.
