Yog vim li cas thiab kev tiv thaiv kev tiv thaiv ua rau steel tawb kom ntab

Cov laj thawj uas ua rau lub tawb steel ntab yog feem ntau:

(1) Lub sijhawm pib thiab zaum kawg ntawm cov pob zeb yog luv dhau, thiab cov pob zeb pob zeb hauv qhov yog ntxov dhau. Thaum cov pob zeb nchuav los ntawm cov kav dej nce mus rau hauv qab ntawm lub tawb steel, qhov txuas ntxiv ntawm cov pob zeb ua ke nqa lub tawb steel.

(2) Thaum ntxuav lub qhov, muaj ntau cov xuab zeb tshem tawm hauv cov av nkos hauv lub qhov. Thaum lub sij hawm lub pob zeb pouring txheej txheem, cov xuab zeb hais nyob rau saum npoo ntawm lub pob zeb, ua ib tug kuj ntom ntom txheej txheej, uas maj mam nce nrog cov pob zeb nto nyob rau hauv lub qhov. Thaum cov xuab zeb txheej txuas ntxiv nrog rau hauv qab ntawm lub tawb steel, nws txhawb nqa lub tawb steel.

(3) Thaum pouring qhob rau hauv qab ntawm lub tawb steel, lub pob zeb ntom ntom yog siab me ntsis thiab lub ncuav nrawm nrawm heev, ua rau lub tawb steel ntab.

(4) Lub qhov qhib ntawm lub tawb steel tsis ruaj khov.Qhov kev ntsuas tseem ceeb rau kev tiv thaiv thiab tuav cov ntab ntawm cov tawb steel suav nrog.

Lub ntsiab kev ntsuas rau kev tiv thaiv thiab tuav lub floating ntawm steel tawb muaj xws li:

(1) Ua ntej drilling, nws yog ib qho tsim nyog yuav tsum tau kuaj xyuas cov phab ntsa sab hauv ntawm lub tes tsho hauv qab. Yog hais tias ib tug loj npaum li cas ntawm cov khoom nplaum accumulates, nws yuav tsum tau muab ntxuav tam sim ntawd. Yog tias nws tau lees paub tias muaj deformation, kev kho yuav tsum tau ua tam sim ntawd. Thaum lub qhov ua tiav, siv lub rauj loj hom tuav lub thoob kom rov nqa thiab txo nws ob peb zaug kom tshem tawm cov xuab zeb thiab av nyob rau sab hauv phab ntsa ntawm cov yeeb nkab thiab xyuas kom meej tias hauv qab ntawm lub qhov yog theem.

(2) Qhov kev ncua deb ntawm lub hoop reinforcement thiab cov phab ntsa sab hauv ntawm lub casing yuav tsum yog tsawg kawg yog ob zaug qhov siab tshaj plaws ntawm cov ntxhib aggregate.

(3) Kev saib xyuas yuav tsum tau them rau qhov zoo ntawm kev ua thiab kev sib dhos ntawm lub tawb steel kom tsis txhob deformation los ntawm kev sib tsoo thaum lub sij hawm thauj mus los. Thaum txo qis lub tawb, qhov tseeb axial ntawm lub tawb steel yuav tsum tau ua kom ntseeg tau, thiab lub tawb hlau yuav tsum tsis txhob tso cai rau poob rau hauv qhov dej. Sab saum toj ntawm lub tawb steel yuav tsum tsis txhob khob, thiab kev saib xyuas yuav tsum tsis txhob sib tsoo nrog lub tawb steel thaum ntxig lub casing.

(4) Tom qab cov pob zeb nchuav ntws tawm ntawm cov kav dej ntawm qhov kub ceev, nws yuav nce mus rau ntawm qhov ceev. Thaum nws tseem tsav lub tawb hlau kom nce siab, lub ncuav ntawm cov pob zeb yuav tsum tau muab tshem tawm tam sim ntawd, thiab qhov tob ntawm cov kav dej thiab qhov siab ntawm cov pob zeb uas twb tau nchuav lawm yuav tsum raug suav nrog siv cov cuab yeej ntsuas. Tom qab nqa cov kav dej mus rau qhov siab, qhov dej tuaj yeem nqa rov qab, thiab qhov tshwm sim nce siab yuav ploj mus.
