Grouting Equipment In Tunnel Construction
Tso lus
Kev tsim kho qhov av feem ntau ntsib cov teeb meem xws li dej nkag mus, cov pob zeb tsis ruaj khov, thiab kev sib haum xeeb hauv av.Groutingyog cov txheej txheem tseem ceeb los daws cov teeb meem no los ntawm kev txhaj tshuaj tshwj xeeb rau hauv pob txha, voids, lossis xoob av kom ntxiv dag zog rau cov qauv thiab tiv thaiv kom tsis txhob tawg.
1. Vim li cas Grouting yog qhov tseem ceeb hauv kev tsim kho qhov
Grouting pab ntau lub hom phiaj:
✔ Waterproofing- Cov ntsaws ruaj ruaj thiab tiv thaiv kev nkag mus hauv av.
✔ Av Stabilization- Txhim kho qhov tsis muaj zog lossis xoob av.
✔ Kev tswj xyuas- Txo cov kev pheej hmoo ntawm kev tawg thaum lub sijhawm khawb.
✔ Pob zeb Reinforcement- Bonds pob zeb tawg rau kev nyab xeeb tunneling.
2. Hom Grouting Khoom Siv Hauv Tunneling
A. Cement Grouting Pumps
● Daim ntawv thov: Sau cov voids loj thiab tawg hauv pob zeb.
● Khoom siv: Siab- lub twj tso kua mis piston lossis cov twj tso kua mis.
● Khoom siv: Cement -raws li slurries (qee zaum nrog additives zoo li bentonite).
B. Chemical Grout Injection Systems
● Daim ntawv thov: Cov kab nrib pleb zoo thiab cov av ntxeem tau uas cov cement grout tsis tuaj yeem nkag mus.
● Khoom siv: Ob-cov khoom siv (2K) cov twj tso kua mis.
● Khoom siv: Polyurethane (PU), acrylic, los yog silicate-raws li resins.
C. Dav Hlau Grouting Rigs
● Daim ntawv thov: Mos av stabilization (xws li, xuab zeb los yog clayey av).
● Khoom siv: Siab - lub dav hlau rotary uas sib tov av nrog grout.
● Qhov tshwm sim: Tsim cov kab los yog phab ntsa rau kev txhawb nqa.
D. Compaction Grouting Rigs
● Daim ntawv thov: Lifting settled structures los yog densifying xoob av.
● Txheej txheem: Tsawg-mobility grout yog txhaj tshuaj kom tshem tawm thiab cov av nyob ib puag ncig.
E. Permeation Grouting Pumps
● Daim ntawv thov: Seepage tswj hauv granular xau.
● Txoj kev: Tsawg- txhaj tshuaj kom puv qhov pores yam tsis cuam tshuam cov qauv av.
3. Cov kauj ruam tseem ceeb hauv Tunnel Grouting Operations
Kauj Ruam 1: Tshawb xyuas qhov chaw
● Kev cojgeotechnical kev tshawb fawbtxhawm rau txheeb xyuas thaj chaw tsis muaj zog, txoj hauv dej, thiab pob zeb tawg.
Kauj Ruam 2: Drill Injection Holes
● Sivpob zeb xyaumlos yoghollow-stem augerslos tsim cov ntsiab lus nkag rau grout.
Kauj ruam 3: Xaiv Txoj Cai Grout Mix
● Cement groutrau cov voids loj.
● Tshuaj groutrau cov kab nrib pleb zoo.
● Polymer groutrau ceev sealing.
Kauj Ruam 4: Txhaj Grout Hauv Kev Tswj Siab
● Saib xyuas kom tsis txhob muajtawgthaj av ib puag ncig.
Kauj Ruam 5: Txheeb xyuas Grout Penetration
● Kev cojcore samplinglos yoggeophysical xeemkom paub meej tias muaj txiaj ntsig.
4. Cov kev coj ua zoo tshaj plaws rau kev ua kom muaj txiaj ntsig zoo
✔ Siv lub sijhawm tiag tiag - xyuas lub sijhawmtxhawm rau taug qab grout ntws thiab siab.
✔ Kho qhov sib tov tsimraws li cov xwm txheej hauv av (piv txwv li, ceev- teeb tsa cov dej ntws tawm).
✔ Ua ntej -test grout viscositykom ntseeg tau tias kev nkag mus tau zoo.
✔ Foob qhov chaw txhaj tshuaj kom raugtiv thaiv rov qab.
5. Advanced Grouting Technologies
● Robotic txhaj tshuabrau qhov tseeb hauv qhov nyuaj - mus rau - mus txog thaj chaw.
● Nanotechnology groutsrau ultra-fine crack sealing.
● Automated siab tswjlos optimize grout kis.
Grouting yog txheej txheem tseem ceeb hauv kev tsim kho qhov av, ua kom muaj kev ruaj ntseg, tiv thaiv dej, thiab ua kom ntev ntev -. Xaiv txoj caikhoom siv groutingthiab cov tswv yim nyob ntawm geological tej yam kev mob, qhov project yuav tsum, thiab xav tau kev tshwm sim.
Tiv tauj peb tam sim kom nrhiav tau siab -kev ua tau zoo grouting kev daws teeb meem!
