Cov kev tsim kho zoo li cas siv rau MJS?

MJS CUG POB(Metro Dav Hlau System), tseem hu ua txhua-puag ncig lub siab tsav dav hlau, tau tsim los daws cov teeb meem ntawm slurry tso thiab ib puag ncig cov kab rov tav txhim kho dav hlau tsim. Tam sim no nws siv tau rau kev kho lub hauv paus, kho cov teeb meem tsis muaj txiaj ntsig thiab kho cov dej seem ntawm phab ntsa sab nrauv. Vim tias siv cov kav dej sib txawv thiab cov av nkos tau raug tshem tawm, thiab cov av me me kom ruaj khov, thiab cov av me Qhov txo qis hauv av siab kuj tseem tuaj yeem lees paub txoj kab uas hla ntawm pawg ntawm pawg.

Pre-tswj

Txij li thaum lubMjs pawgconstruction technology is relatively complex and more difficult than other grouting methods, it is necessary to strictly follow the design requirements during the construction process, do a good job of corresponding technical and safety briefing, and comply with the corresponding operating procedures to ensure the construction quality.

Tom qab drilling rig yog nyob rau hauv qhov chaw, txoj hauj lwm pawg yuav tsum tau tswj tau zoo. Feem ntau, qhov sib txawv ntawm txoj haujlwm tsim yuav tsum tsis pub tshaj 50 hli, thiab kev sib cav sib ceg yuav tsum tsis pub tshaj 1/200.

Ua ntej kev tsim kho ua ntej, lub siab thiab ntws ntawm cov dej siab siab, muaj cua tshuab hluav taws xob, thiab cov txheej txheem kev txhaj tshuaj, thiab cov txheej txheem kev txhaj tshuaj tau txiav txim los ntawm cov piles sib tw. Thaum lub sij hawm tsim kho, lub chaw tswjfwm hauv nruab nrab yuav siv tau rau kev taug qab tsis siv neeg thiab tswj. Sau cov ntaub ntawv ntxaws ntxaws cov ntaub ntawv ntawm ntau cov ntaub ntawv tsim tawm rau ntawm qhov chaw, nrog rau cov kev txhaj tshuaj, vau, slurry rov qab, thiab tawm cov ntaub ntawv tseem ceeb. Nyob rau tib lub sijhawm, cov ntaub ntawv kev tsim kho yuav tsum tau txheeb tawm hauv lub sijhawm, thiab teeb meem yuav tsum tau qhia thiab daws hauv lub sijhawm.

Txhawm rau kom ntseeg tau tias tsis muaj pawg breakage thaum lub laum pas nrig yog qhov sib cuam tshuam rau lub sijhawm ntev vim qee qhov, feem ntau ntawm cov khoom siv sab saud thiab qis dua li kev txhaj tshuaj 100.

Tswj cov machinery ua ntej kev tsim kho kom tsawg cov teeb meem zoo tshwm sim los ntawm cov cuab yeej siv ua tsis tiav thaum kev tsim kho. Ua kev kawm ua ntej ua haujlwm rau lub tshuab ua haujlwm kom paub lawv nrog kev ua haujlwm thiab cov haujlwm ua haujlwm ntawm cov khoom siv. Thaum kev tsim kho, tus neeg mob siab yog lub luag haujlwm rau kev ua haujlwm ntawm cov khoom siv.

Soj ntsuam ua ntej tsim kho

Ua ntej kev tsim kho, cov khoom siv raw, cov tshuab ua haujlwm thiab cov cuab yeej siv tshuaj txau yuav tsum tau kuaj xyuas, feem ntau yog hauv cov hauv qab no:

1 Daim ntawv pov thawj zoo thiab cov ntaub ntawv xeem tshaj tawm ntawm ntau cov ntaub ntawv tso tawm (suav nrog Cement, thiab lwm yam), kev sib xyaw ua ke yuav tsum tau ua kom muaj kev sib tw ntawm cov cai.

2. Seb cov Slurry sib tov sib piv yog haum rau cov av uas muaj qee qhov tshwm sim;

3 Seb cov tshuab thiab khoom siv yog li qub. Ua ntej kev tsim kho, MJS Txhua-Hloov Cov Khoom Siv Hluav Taws Xob Heev Khoom Siv, Cov Khaub Ncaws Dej, thiab cov Laum thiab cov lus qhia yuav tsum tsis muaj kev cuam tshuam;

4 Tshawb xyuas seb cov txheej txheem txau yog haum rau geological. Ua ntej kev tsim kho, kev kuaj cov txheej txheem txau yuav tsum tau nqa tawm. Kev sim tshuaj tsuag yuav tsum tau nqa tawm ntawm Pawg Thawj Pawg. Tus naj npawb ntawm kev sim txau cov nplais cov qhov yuav tsum tsis tsawg dua 2 lub qhov. Yog tias tsim nyog, kho cov txheej txheem txau.

5 Ua ntej kev tsim kho, cov nyom ntawm cov av yuav tsum tau kuaj xyuas kom meej kom ntseeg tau tias kev ua haujlwm drilling thiab txau kom tau raws cov qauv tsim.

6 Khij qhov tseeb thiab rhiab ntawm cov pawg pawg, siab kawg ntsuas thiab ntsuas dej ua ntej tsim.

Hauv-txheej txheem tswj

Thaum lub sij hawm tsim qauv, cov hauv qab no yuav tsum tau them tau rau:

1 Tshawb xyuas cov kev hloov ntawm lub laum pas, qhov chaw khiav ceev, qhov chaw nrawm nrawm nrawm thiab lub sijhawm sib hloov txhua lub sijhawm los saib seb lawv puas muaj raws li cov kev xav tau ntawm cov kev xav tau ntawm cov kab ke

2 Khij cov Maas Slurry sib tov sib piv thiab ntsuas kev txhaj tshuaj nrawm, thiab txhaj tshuaj ceev thaum lub sijhawm txhaj tshuaj ntsuab;

3 Seb cov ntaub ntawv kev tsim kho tiav lawm. Cov kev tsim kho cov ntaub ntawv yuav tsum sau cov ntaub ntawv siab thiab ntws ib zaug ib zaug 1m ntawm kev rub tawm txheej av hloov, thiab tawm cov ntaub ntawv duab yog tsim nyog.

Post-tswj

Tom qab kev tsim kho tiav, cov av txuas ntxiv yuav tsum tau kuaj xyuas, suav nrog: kev ncaj ncees thiab kev sib xyaw ntawm cov av hauv av; Qhov zoo lub taub ntawm cov av hauv av; Lub zog, txoj kab uas nyob nruab nrab, thiab pawg chaw nruab nrab ntawm cov av sib xyaw av; Lub impermability ntawm cov av uas suav av, thiab lwm yam.

1 lub sijhawm soj ntsuam zoo thiab cov ntsiab lus

Txij li cov Caas av ruaj khov yuav tsum muaj qee lub sijhawm, feem ntau yuav tsum ua raws cov ntawv tsim. Yog li ntawd, kev tshuaj xyuas qhov zoo ntawmMjs txauKev tsim kho feem ntau yuav tsum tau nqa tawm tom qab MJS lub dav hlau siab dav hlau ua tiav tiav thiab lub hnub nyoog mus txog lub sijhawm tshwj xeeb hauv kev tsim.

2 Kev Soj Ntsuam Xyuas Kom Zoo thiab Qhov Chaw

Tus naj npawb ntawm kev tshuaj xyuas cov ntsiab lus yog 1% rau 2% ntawm cov naj npawb ntawm kev siv txau qhov sib txau. Rau cov phiaj xwm nrog tsawg dua 20 lub qhov, tsawg kawg ib tus taw tes yuav tsum tau kuaj xyuas, thiab cov uas tsis muaj tshuaj tsuag dua. Cov ntsiab lus soj ntsuam yuav tsum tau teem rau hauv cov chaw hauv qab no: chaw nrog cov khoom lag luam loj, thiab cov chaw nyob qhov twg txawv txav ntawm kev tsim kho.

3 Kev Ntsuam Xyuas Txoj Kev

Kev tshuaj ntsuam ntawm cov dav hlau groouting piles yog feem ntau cov neeg siv khoom ntiag tug. Feem ntau, lub zog compressive dound index ntawm cov ntxhib av yog ntsuas. Ntsuas. Cov qauv yog tau los ntawm kev sib tsoo thiab kev ua yeeb yam, thiab nws tau tsim ua ib qho qauv sib tw. Tom qab ntsib cov cai, sab hauv tsev lub cev ntsuas lub cev thiab cov khoom siv ua haujlwm yog nqa tawm kom kuaj xyuas cov kev sib xyaw ntawm cov paasas av thiab nws cov khoom siv.
