Dab tsi yog cov kev cai dav dav rau kev tsim kho cov txheej txheem steel ntawv pawg cofferdams hauv qab choj hauv nroog?

Koj puas paub dab tsi ntawm steel ntawv pawg? Cov ntawv hlau yog ib hom hlau uas muaj lub qhov ncauj kaw, thiab nws cov ntu ntu muaj xws li cov phaj ncaj, zawj, thiab Z-puab, nrog ntau qhov ntau thiab tsawg thiab cov ntaub ntawv sib cuam tshuam. Cov hom yog Larson style steel ntawv pawg, uas yog cov txheej txheem steel ntawv pawg feem ntau siv hauv kev tsim kho kev lag luam. Nws qhov zoo yog: lub zog siab, yooj yim rau kev tsav mus rau hauv cov av tawv txheej; Kev tsim kho tuaj yeem nqa tawm hauv dej tob, thiab yog tias tsim nyog, kev txhawb nqa kab pheeb ces kaum tuaj yeem muab ntxiv los ua ib lub tawb. Kev ua tau zoo dej tsis zoo; Nws tuaj yeem tsim ntau yam duab ntawm cofferdams raws li xav tau thiab tuaj yeem rov qab siv ntau zaus, ua rau nws siv dav. Tom ntej no, kuv yuav qhia rau koj txog cov kev cai dav dav rau kev tsim kho cov txheej txheem steel ntawv pawg cofferdams hauv nroog txuas hniav?

Kev tsim kho yuav tsum muaj:

1. steel ntawv pawg cofferdam tsis haum rau cov dej ntws nrog cov pob zeb loj thiab cov pob zeb nyuaj.

2. Cov khoom siv kho tshuab thiab qhov ntev ntawm cov ntawv hlau yuav tsum ua kom tau raws li qhov yuav tsum tau ua.

Ua ntej tsav tsheb cov ntawv hlau, kev ntsuas thiab kev soj ntsuam cov ntsiab lus yuav tsum tau teeb tsa saum toj, hauv qab, thiab ntawm ob sab ntawm cofferdam kom tswj tau qhov chaw ntawm qhov ntev thiab luv ntawm cofferdam. Thaum tsav tsheb, cov cuab yeej qhia yuav tsum tau npaj los xyuas kom meej txoj hauj lwm ntawm cov ntawv hlau.

Ua ntej kev tsav tsheb, cov ntaub ntawv tsis muaj dej yuav tsum tau siv los ua kom cov seams ntawm cov ntawv steel pawg xauv kom tsis txhob muaj dej tawm.

5. Qhov kev txiav txim ntawm daim ntawv thov yog ua ke los ntawm cov dej ntws mus rau hauv qab.

6. Cov ntaub ntawv hlau tuaj yeem raug sunk siv txoj hauv kev xws li hammering, vibration, thiab dej jetting, tab sis dej jetting tsis haum rau tog hauv av nplaum.

7. Tom qab kev kho dua tshiab lossis vuam, cov ntawv hlau yuav tsum raug kuaj xyuas thiab tshuaj xyuas siv tib hom steel ntawv pawg. Qhov sib koom ua ke ntawm ob daim ntawv hlau uas nyob ib sab ntawm cov ntawv txuas txuas ntxiv yuav tsum tau staggered nce thiab nqis.

Thaum lub sij hawm tsav tsheb, txoj hauj lwm ntawm pawg yuav tsum tau kuaj xyuas txhua lub sij hawm kom paub tseeb tias nws yog qhov tseeb thiab lub cev pawg yog ntsug. Txwv tsis pub, nws yuav tsum tau kho tam sim ntawd los yog rub tawm thiab tsav tsheb dua.
