Yuav ua li cas xaiv lub Grout Pump rau Tunnel Grouting?

Hauv kev tsim kho qhov av, ntau tus neeg siv khoom tshawb nrhiav "yuav ua li cas xaiv lub twj tso kua mis grout rau qhov av grouting" thaum yuav khoom. Txawm li cas los xij, thaum xaiv tus qauv tiag tiag, ib tus yuav tsum tsis txhob tsom mus rau tus nqi lossis cov ntsiab lus siab; Tsis tas li ntawd, ib qho kev ntsuam xyuas dav dav yuav tsum tau ua raws li txoj hauv kev grouting txoj kev, cov khoom siv grout, ib puag ncig kev tsim kho, tus nqi ntws thiab cov kev xav tau siab, thiab cov cuab yeej ua haujlwm tas li.

1. Vim li cas lub twj tso kua mis Grout tsim nyog rau qhov Grouting?

Feem ntau grouting scenarios nyob rau hauv tunnel engineering muaj xws li ua ntej grouting, radial grouting, grouting ntawm pob zeb loj fractures, backfill grouting qab lub hauv ob sab phlu, grouting qab ntaub thaiv npog ntu, dej-tawm grouting, thiab ntxiv dag zog rau cov tsis muaj zog strata. Hauv cov cheeb tsam uas muaj dej nplua nuj, cov pob zeb tawg, cov xuab zeb txheej, cov av tsis muaj zog, los yog cov dej hauv av siab, cov twj tso kua mis uas tsis tshua muaj siab feem ntau ua tsis tau raws li qhov yuav tsum tau ua kom ruaj khov, tsis tu ncua, thiab tswj tau grouting.
Yog li ntawd, thaum xaiv lub qhov taub grouting twj tso kua mis, cov neeg siv khoom muaj kev txhawj xeeb tshaj plaws tsis yog "lub twj tso kua mis twg yog qhov loj tshaj plaws," tab sis "lub twj tso kua mis twg yog qhov haum rau kuv qhov chaw."

2. Ua ntej, txiav txim siab txoj kev grouting: Cov txheej txheem sib txawv yuav tsum muaj cov twj grouting sib txawv

2.1 Pre-excavation Grouting

Yog hais tias cov dej nplua nuj faults, fractured zones, los yog high-pressure av nyob rau hauv pem hauv ntej ntawm lub qhov, pre-excavation grouting feem ntau yuav tsum tau ua ntej excavation pib. Qhov xwm txheej no xav tau lub twj tso kua mis siab kom ntseeg tau tias cov grout tuaj yeem nkag mus rau pob zeb tawg lossis tsis muaj zog strata.
Rau cov haujlwm zoo li no, peb pom zoo kom xaiv lub twj tso kua mis siab grout. Piv txwv li, Wodetec's HWGP250/450-250D diesel-tsav high-pressure grout txhaj twj tso kua mis, uas muab lub siab tshaj plaws ntawm 450 bar thiab qhov siab tshaj plaws ntws ntawm 250 L/min, yog haum rau high-pressure grouting daim ntaub ntawv xws li cov av reinforcement, subway kev tsim kho, high-speed cho rail seepage, underground engineering. Cov cuab yeej siv hluav taws xob siv hluav taws xob no yog qhov zoo rau cov tunnels, mines, thiab lwm qhov chaw tsim kho sab nraum zoov loj uas cov khoom siv hluav taws xob tsis tuaj yeem ntseeg tau.

2.2 High-Pressure Dav Hlau Grouting

Yog hais tias ib qhov project yuav tsum tau txiav, sib tov, thiab ntxiv dag zog rau cov av tsis muaj zog-xws li nyob rau hauv subway seem, chaw nres tsheb excavation pits, tunnel portal reinforcement, thiab seepage tswj rau underground nruam phab ntsa - ib tug high-pressure dav hlau grouting twj tso kua mis yog qhov tsim nyog xaiv.
Wodetec's HWGP114/500-120D Diesel-driven High-pressure Jet-Grouting Pump yog lub tshuab hluav taws xob diesel-powered high-pressure dav hlau grouting twj muaj peev xwm xa tau qhov siab tshaj plaws ntawm 500 bar thiab tus nqi ntws ntawm 114 L / / min. Nws yog tsim rau high-pressure dav hlau grouting, mos av reinforcement, subway tej yaam num, high-speed rail, underground engineering, waterproofing curtains, mine seepage tswj, thiab txoj kab nqes anchoring.

2.3 Tunnel Lining Backfill Grouting

Yog hais tias voids, compaction teeb meem, los yog delamination muaj nyob tom qab lub hauv paus kev them nyiaj yug los yog lwm yam ob sab ntawm lub qhov, backfill grouting yuav tsum tau. Daim ntawv thov no feem ntau yuav tsum muaj kev ruaj khov grout xa nrog tsawg kawg nkaus pulsation thiab muaj peev xwm ua haujlwm tsis tu ncua, thaum tseem muaj peev xwm siv cov cement slurry, mortar, lossis nplua aggregate slurry.
Wodetec's HWGM50/80PLD-E Ob-Plunger Hydraulic Grout Pump yog tsim rau qhov av liner backfill mortar pumping, av grouting, foundation stabilization, waterproofing, qhov hauv ob sab phlu, underwater foundations, choj decks, thiab nqes hav grouting.

3. Dab tsi yog qhov tseem ceeb yuav tsum tau txiav txim siab thaum xaiv lub qhov taub Grouting Pump?

3.1 Grouting Pressure: Siab dua tsis yog ib txwm zoo dua-Nws yuav tsum sib haum rau Geological tsim

Ntau tus neeg muas zaub nug ncaj qha: "Kuv xav tau lub siab npaum li cas rau qhov av grouting?" Hauv kev muaj tiag, grouting siab yuav tsum tau txiav txim siab raws li pob zeb tawg, dej hauv av siab, qhov tob tob, slurry viscosity, thiab lub voj voog tsim grouting.
Yog tias qhov siab qis dhau lawm, lub grout tsis tuaj yeem kis tau zoo; Yog hais tias lub siab siab dhau lawm, nws yuav ua rau pob zeb tawg, grout to, av heaving, los yog kev cuam tshuam ntawm cov qauv. Yog li ntawd, thaum xaiv lub twj tso kua mis muaj zog cement grout, qhov tseem ceeb yuav tsum tau muab rau cov khoom siv nrog kev hloov siab, kev tswj kom ruaj khov, thiab kev tiv thaiv kev nyab xeeb.
Piv txwv li, HWDH75/100 PI-E High-Pressure Vertical Grouting Pump muaj qhov hloov kho siab ntau ntawm 0-100 bar thiab tus nqi ntws ntawm 0-75 L/min, ua rau nws tsim nyog rau txoj hauv kev xws li permeation grouting, consolidation grouting, backfill grouting, curtain-grouting, thiab high-strength grouting. Rau grouting nyob rau hauv tunnels, me me-cross-section underground tej yaam num, mines, thiab dam foundations, hom ntsug high-pressure grouting twj tso kua mis nta ib tug compact tsim, yooj yim ntawm kev khiav hauj lwm, thiab tsis tshua muaj nqi txij nkawm.

3.2 Flow Rate: Siab yog qhov tseem ceeb rau grouting me me fissures, thaum txaus tus nqi yog qhov tseem ceeb rau loj-scale filling

Rau fissure sealing, ua ntej qhov cuab lub zog, los yog qhov sib sib zog nqus-qhov grouting, lub hom phiaj yog feem ntau nyob rau hauv siab stability; rau backfilling qab linings, void filling, shield tunneling grouting, los yog loj-thaj av reinforcement, lub hom phiaj yog nyob rau hauv tas li ntawd mus txaus tus nqi.
Wodetec's HWGP440/50PI-22E High-Pressure Horizontal Grouting Pump muab qhov siab tshaj plaws ntawm 440 L / min thiab siab tshaj plaws ntawm 5 MPa, ua rau nws tsim nyog rau cov haujlwm hauv mining, geological drilling, railways, highways, water conservancy and hydropower, buildings, foundations, high-pressure. Rau qhov tunnel backfill grouting los yog foundation grouting tej yaam num yuav tsum tau high-flow xa ntawm cement slurry, hom kab rov tav high-flow grouting twj tso kua mis muaj qhov zoo sib xws.

3.3 Hom Slurry: Cement Slurry, Mortar, Bentonite, lossis Tshuaj Grout?

Cov khoom siv dav siv hauv qhov av grouting muaj xws li cov cement slurry, microfine cement grout, bentonite cement slurry, mortar, waterproofing grout, thiab tshuaj grout. Txawv slurries qhov chaw sib txawv xav tau ntawm lub twj tso kua mis:
Cement slurry thiab bentonite slurry xav tau cov twj uas muaj kev hnav zoo thiab muaj peev xwm xa khoom ruaj khov; mortar thiab nplua-aggregate slurries xav tau cov cuab yeej uas tso cai rau qee qhov me me kom dhau mus; chemical grouts muab qhov tseem ceeb dua rau kev ntsuas qhov tseeb, tswj kev siab, thiab cov khoom siv sib xws.
Yog tias tus neeg siv khoom siv cov cement slurry lossis mortar rau qhov av grouting, HWGM90/100PLD-E Compact Cement Mortar Txhaj Twj yog qhov kev xaiv zoo heev. Nrog rau qhov ntsuas ntws ntawm 0-90 L / / min thiab ntsuas siab ntawm 0-100 bar, cov qauv no tsim nyog rau kev xa cov cement slurry, mortar, thiab nplua aggregate sau cov ntaub ntawv nrog particle loj ≤8 hli. Nws tuaj yeem siv rau hauv cov dej num xws li qhov av rov qab, kev txhim kho hauv av, dej tsis qab thiab xau sealing, underwater foundations, choj lawj grouting, thiab nqes hav anchoring.

3.4 Fais fab Source: Diesel-Driven lossis Electric-Driven?

Qhov chaw tsim kho qhov chaw muaj qhov chaw tsis yooj yim, thiab kev xaiv ntawm lub zog hluav taws xob kuj cuam tshuam rau kev xaiv cov khoom siv.
Yog tias lub hwj chim ntawm qhov chaw tsim kho tsis ruaj khov, lossis yog tias qhov project yog nyob rau hauv lub mine, roob toj siab, qhov kev txuag dej, lossis qhov chaw loj sab nraum zoov, cov twj siv hluav taws xob siv hluav taws xob tau yooj yim dua rau kev xa tawm. Piv txwv li, HWGP250/450-250D thiab HWGP114/500-120D yog ob qho tib si diesel-tsav qauv haum rau loj-scale qhov thiab high-pressure engineering chaw.
Yog tias lub zog ruaj khov muaj nyob rau ntawm qhov chaw thiab muaj qhov yuav tsum tau hais txog lub suab nrov, emissions, thiab kev yooj yim ntawm kev saib xyuas, cov twj siv hluav taws xob-hydraulic grouting twj lossis hluav taws xob kab rov tav grouting twj zoo dua. Piv txwv li, HWDH70 & 90 Hydraulic High-Pressure Grout Pump yog hydraulically tsav, nrog lub ntsuas siab ntawm 10 MPa thiab ntws tus nqi ntawm 0-70 L/min los yog 0-100 L/min. Nws yog tsim rau ntau yam kev siv, xws li av grouting, foundation reinforcement, waterproofing, qhov hauv ob sab phlu, choj lawj siv, thiab txoj kab nqes grouting.
