Cement Hloov Pump

Yuav siv cov cement hloov twj tso kua mis hauv qhov engineering li cas?

Daim ntawv thov ntawm peb lub tog raj kheej BW250 xis mas hloov twj tso kua mis nyob rau hauv qhov engineering yog feem ntau xav txog nyob rau hauv cov nram qab no yam:

• Grouting thiab dej thaiv technology:Hauv kev tsim kho qhov av, cov cement grouting twj yog siv rau grouting thiab dej thaiv los tswj cov dej nkag thiab tawg. Grouting cov ntaub ntawv yuav tsum muaj zoo fluidity, stability, thiab siab compressive zog thiab impermeability. Hauv kev tsim kho tiag tiag, cov khoom siv grouting siv feem ntau yog silica cement thiab dej iav. Lub configuration piv ntawm slurry yog txiav txim los ntawm ntau yam kev sim. Piv txwv li, qhov sib piv ntawm cov dej-cement yog 0.8: 1, qhov sib piv ntawm cov cement rau cov iav dej yog 1:0.4, thiab disodium hydrogen phosphate yog ntxiv los ua ib qho retarder.
• Grouting system xaiv:BW250 MAAs hloov twj tso kua mis siv hauv kev tsim kho suav nrog tag nrho cov hydraulic drilling rigs, grouting twj, mixers thiab high-pressure hoses. Txoj kev ob-tube grouting feem ntau yog siv. Tom qab cov cement slurry thiab dej iav sib tov thiab nplawm ntawm lub qhov ncauj, lawv tau txhaj rau hauv cov yeeb nkab ntawm qhov siab kom tso cai rau cov slurry nkag mus rau hauv cov kab nrib pleb, sau cov qhov khoob tom qab solidification, thiab tiv thaiv dej to.
• Tunnel reinforcement kho:Cement grouting thev naus laus zis tau siv dav hauv kev kho qhov taub vim nws qhov yooj yim, ceev thiab cov yam ntxwv zoo. Tshwj xeeb tshaj yog nyob rau hauv kev tsim kho ntawm ntiav faus thiab mos nyob ib ncig ntawm lub pob zeb tunnels thiab kev kho mob ntawm lub tunnels, peb txoj kev ntawm av grouting, qhov chaw ua hauj lwm nto grouting, thiab qhov periphery qhov tob qhov tob grouting yog ua ke los xyuas kom meej kev tsim kho.
• Nto grouting:ntxig rau ib qho kev sib txuas ntawm qhov sib tsoo ntawm qhov chaw ntog, thiab pib grouting raws li qhov predetermined water-cement ratio thiab grouting siab kom sib sau cov av saum npoo thiab tiv thaiv cov dej saum npoo los ntawm ntws mus rau hauv lub qhov thiab ua kom lub cev qhuav dej.

Daim ntawv thov ntawm peb lub tog raj kheej BW250 MAAs hloov twj tso kua mis nyob rau hauv qhov engineering yog multifaceted, nrog rau cov dej thaiv, qhov cuab lub zog, ntsaws, thiab lwm yam. Los ntawm kev sib txawv grouting technologies thiab txoj kev, kev tsim kho efficiency thiab kev ruaj ntseg ntawm tunnel engineering tau zoo lawm.
Grouting ntawm lub ntsej muag ua haujlwm hauv qhov av:cov yeeb nkab loj tso grouting thiab I-shaped thav duab txhawb nqa tau txais yuav hauv qhov. Cov cement slurry yog txhaj rau hauv cov yeeb nkab loj, thiab qhov pib qhov siab yog 0.5 ~ 1Mpa thiab qhov kawg siab yog 2Mpa. Lub hauv paus ntsiab lus yog tswj cov cement slurry kom tsis txhob tawm ntawm qhov chaw.

Grouting ntawm qhov ntiav nyob ib ncig ntawm lub qhov:Txhawm rau tiv thaiv cov pob zeb nyob ib puag ncig ntawm lub phaj ntsaws sab nraum cov yeeb nkab loj los ntawm kev poob, grouting steel paj kav yog teem rau grouting kev them nyiaj yug. Ua ntej grouting, pob zeb yog sprayed los kaw lub ntsej muag kom tsis txhob to, thiab tom qab ntawd cov cement dej iav slurry yog grouting. Thawj qhov siab tshaj plaws yog {{0}}.1 ~ 0.3Mpa thiab qhov kawg siab yog 0.5Mpa.

Txhim kho kev tsim kho efficiency thiab kev nyab xeeb:Cov cement hloov twj tso kua mis txhim kho kev tsim kho kom zoo hauv qhov av engineering nrog nws cov kev ua haujlwm siab thiab ruaj khov, thiab ua rau lub sijhawm tsim kho, muab kev lav zoo rau kev ua tiav ntawm qhov project. Lub twj tso kua mis grouting yog ib qho yooj yim rau kev khiav lag luam thiab tswj, uas txo cov kev siv zog ntawm cov neeg ua haujlwm. Nws yog txawm peem rau nrog ib tug ntse tswj system uas yuav saib xyuas ntau yam tsis nyob rau hauv lub grouting txheej txheem nyob rau hauv lub sij hawm ntawm lub sij hawm los xyuas kom meej lub stability thiab kev cia siab ntawm lub grouting nyhuv.

Daim ntawv thov kev lag luam:Cement mortar grouting tshuab yog dav siv nyob rau hauv tunnel excavation thiab txij nkawm, txoj kev, choj, pas dej ua ke, mine kev tsim kho thiab lub hauv paus kev kho mob tej yaam num ntawm high-sawv vaj tse thiab ntau yam high-pressure grouting tej yaam num, tshwj xeeb tshaj yog nyob rau hauv lub tunnel tej yaam num rau plugging leaks, kev tsim kho pob qij txha, kev sib hais haum. pob qij txha, expansion pob qij txha, thiab pas dej ua ke hauv qab tawg. Waterproof plugging kev tsim kho.

Tom qab BW250 peb lub tog raj kheej cement hloov twj tso kua mis tau nres lossis rov nruab rau lub sijhawm ntev, cov kev npaj hauv qab no yuav tsum tau ua ua ntej pib.
1. Xyuas seb puas muaj cov roj lubricating txaus hauv txhua qhov.
2. Tshawb xyuas seb lub tshuab nqus dej ntawm lub lim tsis raug thaiv.
3. Xyuas seb puas muaj kev cuam tshuam hauv kev txav ntawm txhua qhov chaw.
4. Tshawb xyuas qhov tseeb thiab kev ntseeg siab ntawm cov tshuab xa tawm.
5. Txheeb xyuas qhov looseness ntawm fasteners, tshwj xeeb tshaj yog cov ntsia hlau zawm ntawm roj hmab piston locking txiv ntoo, hla lub taub hau thiab piston pas nrig txuas xov.
6. Txheeb xyuas qhov siab qhov siab ntawm lub tshuab twj grout. Qhov siab tshaj plaws suction qhov siab ntawm lub twj tso kua mis yuav tsum tsis pub tshaj 2.5 meters nyob rau hauv cov cheeb tsam hauv qab no 1000 meters saum toj no hiav txwv theem. Hauv thaj chaw siab tshaj 1000 meters saum toj no hiav txwv theem, qhov siab siab ntawm lub twj tso kua mis yuav tsum raug txo raws li kev txo qis hauv cheeb tsam atmospheric siab.
7.Saib qhov chaw ntawm lub lim dej rau hauv lub tank av nkos. Feem ntau, cov av nkos yuav tsum qis dua 0.3-0.5 meters, thiab cov lim dej yuav tsum tsis pub tsawg tshaj 0.5 meters deb ntawm qab ntawm cov av nkos.
