Ib hom tshiab ntawmlub txiv ntoo tig lub lognyuam qhuav ua tiav kev lees txais kev siv tshuab thiab tau tso tawm ntau los daws cov teeb meem ntawm kev nyuaj thiab tsis ua haujlwm zoo ntawm cov pas nrig khi hauv kev tsim kho choj formwork. Cov txiv ntoo no tau ua kom zoo dua qhov kev sib hloov tom, ua rau cov khoom siv tiv thaiv kev sib tsoo, thiab tuaj yeem hloov kho rau cov pas nrig khi tshwj xeeb ntawm D10-D25 cov lus qhia. Qhov yuam kev haum ntawm cov qauv nkhaus thiab tsis sib xws yog tswj tau hauv 0.5 hli, thiab kev ua haujlwm du tseem tuaj yeem ua tiav hauv qhov kub qis (-15 ℃), nrog rau 40% nce ntxiv hauv kev teeb tsa piv rau cov txiv ntoo ib txwm muaj.

   Tam sim no, cov txiv ntoo no tau siv rau hauv kev tsim kho ntawm ob lub choj hla dej hauv thaj av Yangtze River Delta, nrog rau cov khoom siv ntau dua 8000 pawg. Raws li cov lus tawm tswv yim los ntawm chav tsev tsim kho, nws cov xov tau kho nrog kev quenching siab zaus, nrog rau kev hloov pauv ntau dua 50 zaug, uas yuav luag ntev dua li cov txiv ntoo ib txwm muaj; Nrog kev siv lub wrench tshwj xeeb, lub sijhawm khi rau ib tus pas nrig tau raug txo los ntawm 3 feeb mus rau 45 vib nas this, ncaj qha luv lub sijhawm tsim kho ntawm cov txheej txheem sib dhos choj los ntawm 12 hnub. Cov xaj lag luam tau teem sijhawm txog rau peb lub hlis thawj zaug ntawm xyoo tom ntej.
