Ulayini wokukhiqiza wamapayipi kathayela webhuloho we-Bridge prestressed kanye nolayini wokukhiqiza wamapayipi we-grouting uthunyelwa kumakhasimende e-Chengdu,
Imishini yepulasitiki yaseQingdao Cuishi ekhiqiza izifutho zepulasitiki ipayipi lepulasitiki likamgwaqo onguthelawayeka Ibhuloho elicijile lepulasitiki elicijile ngokhonkolo oluboshwe ngensimbi enemifunso yepulasitiki ecindezelwe ngaphambili.
Lo mkhiqizo usetshenziselwa ikakhulukazi umasipala, ukuvikelwa kwemithambeka, ukuvunguza kwepulasitiki okuqinile kwebhuloho lejubane eliphezulu, ipayipi lebhuloho likathayela eligxilile, ngesikhathi sokuthululwa ukuze kuvikelwe umucu wensimbi ekungcoleni, ukuqinisekisa ukungezwani komzimba.Izinsimbi zepulasitiki ezicindezelwe izici eziyinhloko: 50 55 60 65 70 75 80 85 90 95 100 105 110 115 120mm ukujiya kodonga 2.2-3cm
Izivunguvungu zepulasitiki ezicindezelwe yizimbongolo ezinodonga olulodwa olukhishwe i-plastic extruder nge-high-density polyethylene (i-HDPE) yezakhiwo zikakhonkolo ezinengcindezi yangemuva njengepayipi elinezimbobo ezinezimbambo ezicindezelwe ngaphambili.Iyindlela ehlukile yokuvuthela kwensimbi yokuqala ekwakhiweni kwebhuloho nokwakhiwa.Amapayipi epulasitiki ahlukaniswe abe izigaba ezimbili: amapayipi ayindilinga namapayipi ayisicaba, axhunywe ekusetshenzisweni kwangempela ngezinhlobo ezahlukene zezixhumi zepulasitiki.Izinto ezisetshenziswayo zemibhobho yepulasitiki ecindezelwe yi-HDPE.Ukumelana nokugqwala kwayo kungcono kakhulu kunokwensimbi, ayikwesabi ukugqwala kwe-asidi ne-alkali, ayizigqwali ngokwayo, futhi ingavikela ngempumelelo izimbambo ezicindezelwe ekugqwaleni.

Izivunguvungu zePlastiki njengendlela ye-post-tensioning ye-post-tensioning ye-porous material iyingxenye ebalulekile yesistimu ecindezelwe isikhathi eside, ubunjiniyela obucindezelwe isikhathi eside besebenzisa izinsimbi zensimbi njengempahla ye-pore, ukuze banqobe ukushiyeka kwensimbi yokufaka uphawu okungalungile, ukulimala okulula, kulula ukugqwala, ukumelana nokungqubuzana okukhulu, kodwa futhi ukuze unikeze isivimbeli esengeziwe sokuqeda ukugqwala kwezimbambo ezicindezelekile, kunconywa ukusebenzisa i-polyethylene noma i-polypropylene eyenziwe ngezivunguvungu zepulasitiki njengomkhiqizo woguquko onendlela yokubopha ngemuva kokuqina ukuze uthuthukise impilo. yesakhiwo
