Thaum lub sij hawm piling, yog tias pom muaj teeb meem zoo, chav tsev tsim kho yuav tsum tsis txhob tuav lawv tus kheej. Nws yuav tsum tau tshaj tawm rau tus thawj saib xyuas thiab tus tswv, thiab tom qab ntawd ua haujlwm nrog tus tsim, kev soj ntsuam, thiab lwm lub tuam tsev muaj feem cuam tshuam los soj ntsuam thiab kawm txog cov teeb meem thiab tsim cov kev daws teeb meem kom raug. Lub tuam tsev tsim qauv yuav tsum tshaj tawm tsab ntawv ceeb toom kev hloov kho. Cov txheej txheem muaj xws li: kev them nyiaj rau kev sib hais haum, kev pab pawg ntxiv, kev sib koom ua pawg pub noj thiab ntxiv, kev kho, qhov loj pawg cap, thiab cov txheej txheem sib xyaw ua ke. Cov no tau piav qhia luv luv hauv qab no:
1. Kev them nqi kho mob#drill rau av#
Txoj kev no tuaj yeem siv tau thaum pawg precast tsis sib sib zog nqus hauv cov av, lossis thaum cov pawg tsav tau nqa los ntawm cov av bulging.
2. Re-Pile Method
Ib qho ntawm ob txoj hauv qab no tuaj yeem siv tau:
2.1 Re-pile ua ntej pawg cap. Thaum cov pawg sib nrug me me, ib txoj hauv kev drilling qhov ua ntej, tom qab ntawd cog cov pawg, thiab tom qab ntawd tsav cov pawg tuaj yeem txais yuav.
2.2 Re-Pile siab zoo li qub pawg tom qab pawg cap lossis hauv qab daus ua tiav. Qhov kom zoo dua ntawm txoj kev no yog tias lub hau npog lossis cov qauv hauv qab daus tuaj yeem siv los dais qhov kev tsim cov tshuaj tiv thaiv ntawm cov pawg siab zoo li qub. Cov chaw ua haujlwm yooj yim, kev ua haujlwm yooj yim, thiab nws tsis ncua lub sijhawm tsim kho.#drill rau av #
3. Ua ke Re-pile thiab tsav txoj kev
Thaum cov pawg tsav tau txuas nrog rau hauv cov ntu thiab tau tsav ib qho los ntawm ib qho, cov kab txuas tsis zoo yuav ua rau cov pob qij txha sib txuas sib cais. Hauv qhov no, kev sib koom ua ke re- pawg thiab tsav txoj kev tuaj yeem siv tau. Ua ntej, cov pawg uas muaj kev tsis ntseeg yog rov- tsav los ua kom lawv tog thiab ua kom cov pob qij txha xoob kom ua rau lawv muaj peev xwm ntsug. Qhov thib ob, qee cov pawg ua tiav tau ntxiv kom tsim nyog. Ntawm qhov tod tes, qhov no ua rau qhov tsis muaj peev xwm ntsug ntawm tag nrho lub hauv paus, thiab ntawm qhov tod tes, cov re-tsav ua tiav pawg tuaj yeem tiv taus seismic loads.
4. Txoj kev kho
Yog tias pawg tilted tab sis tsis tawg, thiab qhov ntev ntawm pawg yog luv luv, lossis yog tias qhov tilting yog tshwm sim los ntawm kev khawb ntawm lub hauv paus pit tab sis tsis tawg, txoj kev ntawm ib feem excavation tom qab jacking rau kho thiab repositioning yuav siv tau.#drill rau av#
