Nrog rau kev loj hlob ntawm txoj kev loj hauv ntiaj teb, ntau yam teeb meem tau tshwm sim thaum siv, xws li kev puas tsuaj ntawm txoj kev thiab kev sib haum xeeb ntawm txoj kev. Cov teeb meem no yuav cuam tshuam rau kev nyab xeeb thiab kev nplij siab ntawm kev tsav tsheb, thiab tseem yuav cuam tshuam rau kev ua haujlwm ntawm lub tsheb. Taishaninc geogrid los yog hom tshiab ntawm cov khoom siv geosynthetic. Piv nrog rau lwm cov ntaub ntawv, nws muaj nws cov kev ua tau zoo thiab kev ua tau zoo. Nws muaj lub zog siab, muaj zog load-bearing muaj peev xwm, muaj zog durability, yooj yim kev tsim kho thiab kev pab lub neej ntev. Los ntawm kev siv polyester geogrid reinforcement los txhim kho cov kabmob muaj peev xwm ntawm cov av mos subgrade thiab txo nws cov kev sib haum xeeb tom qab kev tsim kho, kev tsim kho tshuab ntawm polyester geogrid reinforced subgrade tau sib tham, thiab kev tsim kho kev tswj xyuas kev ntsuas tau ua tiav. Kev siv cov txiaj ntsig ntawm qhov project no qhia tau hais tias polyester geogrid muaj qhov zoo ntawm lub zog siab, muaj zog load-bearing muaj peev xwm, muaj zog durability, yooj yim siv, thiab kev pab lub neej ntev, thiab tuaj yeem siv rau hauv cov haujlwm zoo sib xws.
Taishaninc polyester geogrid reinforced subgrade pavement yog dav siv nyob rau hauv European txoj kev loj kev tsim kho. Lub luag haujlwm tseem ceeb ntawm polyester geogrid siv nyob rau hauv txoj kev loj xws li kev txhawb zog, kev tiv thaiv, kev pom, kev tso dej thiab kev sib cais. Polyester geogrid feem ntau yog tsim rau txoj kev loj mos av subgrade kho, subgrade reinforcement, platform backfilling, splicing ntawm tshiab thiab qub txoj kev, pom thiab kua, thiab lwm yam.
(1) Ua ntej kev tsim kho, cov ntaub ntawv polyester geogrid yuav tsum raug xaiv raws li kev tsim qauv. Polyester geogrid siv nyob rau hauv qhov project no yog unidirectionally stretched high-density polyethylene polyester geogrid. Ua ntej tso, polyester geogrid yuav tsum tau kuaj xyuas. Yog tias pom muaj wrinkles, lawv yuav tsum tau straightened mechanically los yog manually.
2) Cov muab tub lim siv rau hauv qhov project yuav tsum ua raws li cov kev cai hauv qab no: cov dej permeability ntawm cov muab tub lim yuav tsum zoo, thiab nws cov kev sib txhuam sab hauv yuav tsum tswj tsis pub dhau 30 °. Yog tias tsim nyog, kev ntsuam xyuas geotechnical ntawm qhov chaw yuav tsum tau ua ntawm qhov muab tub lim; muaj cov npoo ntse thiab cov ces kaum hauv qhov muab tub lim. Cov ntsiab lus ntawm cov av yuav tsum tau tswj tsis pub dhau 15% ntawm tag nrho cov khoom siv kom tsis txhob muaj kev puas tsuaj rau polyester geogrid los ntawm cov npoo ntse; qhov loj me me ntawm cov av hauv qhov muab tub lim yuav tsum tswj tsis pub dhau 100 hli.
Thaum excavation thiab kev tsim kho ntawm lub hauv paus txaj, koj tsuas yog yuav tsum tau ua raws li kev siv tshuab ntawm lub hauv paus txaj. Tsis muaj lus piav qhia ntxiv hauv kab lus no. Txawm li cas los xij, thaum lub hauv paus txaj excavation tsim, tshwj xeeb yuav tsum tau them nyiaj rau kom ntseeg tau tias lub hauv paus txaj excavation raws li tus tsim. thiab kev tsim kho vaj tse. Nyob rau tib lub sijhawm, kev ntsuas dej tsis zoo thiab kev tso dej yuav tsum tau coj mus rau hauv lub hauv paus qhov tob kom txo tau qhov tsis zoo ntawm cov dej. Thaum qhov kev khawb ntawm lub hauv paus txaj yog leveled thiab compacted, lub gravel cushion tuaj yeem muab tso rau tom qab kuaj xyuas kom nws tsim nyog. Nws thickness yuav tsum tau tswj ntawm 30 cm. Tom qab lub gravel cushion tau pw, nws yuav tsum tau leveled nyob rau hauv lub sij hawm, thiab lub zos tso cai qhov siab qhov sib txawv ntawm qhov chaw ntawm lub cushion yuav tsum tau tswj nyob rau hauv 10cm. Tom qab lub gravel cushion yog pw, tso ntawm polyester geogrid tuaj yeem pib. Ua ntej, txiav lub hauv av reinforced grating raws li tus tsim yuav tsum tau, thiab ces nteg tawm raws li qhov yuav tsum tau ntawm tus tsim drawings. Ib qhov ntev ntawm grating yuav tsum tau tshwj tseg sab nraum qhov chaw nqes hav rau rov qab ntim. Thaum lub sij hawm tso txheej txheem ntawm polyester geogrid, yuav tsum tau them tshwj xeeb mloog mus rau lub fact tias cov kev nyuaj siab ntawm polyester geogrid yuav tsum tau nteg nyob rau hauv lub longitudinal axis. Polyester geogrids yuav tsum tsis txhob muaj cov pob qij txha raws lub ntsiab kev ntxhov siab.
Thaum tso polyester geogrid, qhov chaw, qhov ntev thiab kev taw qhia tau teeb tsa hauv cov duab kos duab yuav tsum ua raws. Qhov sib tshooj dav ntawm txoj kev yuav tsum tau tswj ntawm 10 cm. Tom qab tso tiav lawm, U-puab ntsia hlau yog siv los txhawb cov polyester geogrid. Qhov sib nrug ntawm U-zoo li tus rau tes yuav tsum tau khaws cia ntawm qhov kev ncua deb. Kev kho ntawm U-zoo li tus rau tes tuaj yeem tiv thaiv polyester geogrid los ntawm kev hloov pauv thaum lub sij hawm tsim kho. Polyester geogrid cov pob qij txha raws cov lus qhia tsis tseem ceeb yog khi nrog nylon hlua, tsis tas yuav tsum tau sib tshooj. Qhov sib nrug ntawm kev sib khi yuav tsum tau tswj hauv lm.
Tom qab cov polyester geogrid tau muab tso rau raws li qhov xav tau, kev tsim kho rov qab yuav tsum tau ua raws sijhawm. Lub sij hawm raug ntawm polyester geogrid yuav tsum tsis txhob ntev dhau los tiv thaiv cov teeb meem kev laus los ntawm lub hnub raug. Thaum lub sij hawm tsim kho backfilling, qhov luaj li cas ntawm cov muab tub lim siv yuav tsum tsis pub tshaj 1/2 ntawm cov dov txheej. Thaum lub sij hawm kev tsim kho, ob qhov kawg ntawm polyester geogrid yuav tsum tau ua ntej thiab yuav tsum tau tsim ib lub platform longitudinal lossis txoj kab tsheb khiav. , thiab ces qhov Scope ntawm backfilling yuav tsum tau nthuav dav nyob rau hauv lem. Thaum lub sij hawm rebound kev tsim kho ntawm cov muab tub lim, tsheb tsheb raug txwv nyob rau hauv ua tiav polyester geogrid.
Backfill leveling tuaj yeem ua tiav mechanically lossis manually. Tom qab leveling kho, lub zos qhov siab sib txawv ntawm qhov chaw yuav tsum tau tswj nyob rau hauv Scm. Thaum dov kev tsim kho yog nqa tawm, nws yuav tsum tau nqa tawm nyob rau hauv kev txiav txim los ntawm ob qho tag nrho mus rau nruab nrab. Txoj kev tsim kho rov qab tsis raug tso cai. Thaum lub sij hawm tsim kho, txoj kev cov menyuam yuav tsum tau tsav tsheb raws txoj kab ntev ntawm lub embankment kom tsis txhob muaj qhov tshwm sim ntawm kab rov tav tsav tsheb thiab dov. Tom qab dov kev tsim kho ntawm txhua txheej ntawm cov muab tub lim tiav, nws cov compaction yuav tsum tau kuaj xyuas kom ntseeg tau tias nws ua tau raws li qhov yuav tsum tau ua ua ntej kev tsim kho ntawm cov txheej txheem tom ntej. Lub compaction degree ntawm sau yog tswj raws li cov kev cai dav dav rau embankments.
