dej conductivity
Lub concave-convex hollow rib qauv ntawm cov dej tsis muaj dej thiab cov dej tiv thaiv lub rooj tsavxwm tuaj yeem ua kom dej nag sai thiab zoo, txo qis lossis txawm tias tshem tawm cov dej tsis zoo ntawm cov txheej txheem dej.Los ntawm txoj cai ntawm kev ua dej num no, cov txiaj ntsig ntawm kev ua dej tsis zoo tuaj yeem ua tiav.
Waterproof kev ua tau zoo: Polyethylene (HDPE) polystyrene (PVC) waterproof thiab dej tiv thaiv board khoom nws tus kheej yog ib tug zoo waterproof khoom.Los ntawm kev siv txoj kev sib txuas txhim khu kev qha, cov dej tsis zoo thiab cov kav dej ua rau cov khoom siv dej tsis zoo.
kev tiv thaiv
Lub rooj tsav xwm tsis muaj dej thiab cov dej pov thawj tuaj yeem tiv thaiv cov qauv thiab cov txheej txheem dej tsis zoo, thiab tiv taus ntau yam acids thiab alkalis hauv cov av thiab cov hauv paus pos ntawm cov nroj tsuag.Nws tiv thaiv vaj tse thiab waterproofing los ntawm kev puas tsuaj thaum backfilling hauv qab daus sab nrauv phab ntsa.
Lub suab rwb thaiv tsev thiab qhov cua thiab noo noo-pov thawj muaj nuj nqi:
Cov ntaub ntawv hauv chav kuaj pom tau hais tias polyethylene (HDPE) polyvinyl chloride (PVC) tsis muaj dej tsis zoo thiab cov dej pov thawj tiv thaiv tuaj yeem txo cov suab nrov sab hauv tsev ntawm 14 decibels, 500HZ, thiab muaj cov suab nrov txo thiab suab rwb thaiv tsev ua haujlwm.Thaum siv rau hauv av los yog ntawm phab ntsa, cov dej tsis muaj dej tsis zoo tuaj yeem ua lub luag haujlwm zoo hauv qhov cua thiab noo noo.
1. Dab tsi yuav tsum tau them nyiaj rau hauv kev tsim kho?
1) Thov khaws cov kav dej hauv qhov chaw qhuav thiab qhov cua, tiv thaiv kom tsis txhob raug tshav ntuj, thiab kom deb ntawm qhov hluav taws kub.
2) Thov tso lub qhov dej tiv thaiv vertically lossis horizontally, tsis txhob qaij lossis hla kab rov tav, qhov siab stacking yuav tsum tsis pub tshaj 3 txheej, thiab cov khoom hnyav yuav tsum tsis txhob muab tso rau.
3) Thaum tso, nws yuav tsum tiaj tus thiab ntuj, thiab nteg raws txoj kab nqes lossis raws li cov dej ntws.
2. Muaj pes tsawg pawg ntawm cov kav dej?
Feem ntau siv cov kav dej hauv kev tsim kho muaj xws li: cov kav dej yas, cov kav dej cia, cov khoom siv coiled cov kav dej, cov kav dej los tiv thaiv, cov kav dej sib xyaw, cov kav dej peb sab, cov ntawv zoo li cov kav dej, thiab lwm yam.
3. Nws feem ntau siv qhov twg?
Greening project: garage roof greening, ru vaj, vertical greening, sloping roof greening, football field, golf course.
Kev tsim kho hauv nroog: tshav dav hlau, txoj kev subgrade, subway, qhov av, pov tseg.
Kev tsim kho engineering: txheej txheej sab saud lossis qis ntawm lub hauv paus tsev, cov phab ntsa sab hauv tsev thiab sab nraum zoov thiab cov phiaj xwm hauv qab daus, nrog rau lub ru tsev, lub ru tsev los tiv thaiv dej thiab cov txheej txheem cua sov, thiab lwm yam.
Kev txuag dej: dej los tiv thaiv cov dej hauv cov reservoirs, reservoirs, thiab cov pas dej cuav.
Traffic engineering: txoj kev, railway subgrade, embankment thiab txoj kab nqes tiv thaiv
4. Yuav ua li cas rau nruab?
1) Ntxuav cov khib nyiab ntawm qhov chaw tso thiab ua kom cov cement kom tsis txhob muaj qhov pom tseeb ntawm qhov chaw.Lub ru tsev ntawm qhov chaw nres tsheb sab nraud thiab lub ru tsev vaj yuav tsum muaj txoj kab nqes ntawm 2-5‰.
2) Nws tuaj yeem mloog zoo rau cov dej tawm ntawm cov kav dej mus rau cov kav dej nyob ze lossis cov kav dej hauv nroog ze.
3) Cov av hauv qab daus yog dej-pov thawj, thiab hauv pem teb tau tsa saum lub hauv paus, uas yog, txheej txheej ntawm cov kav dej yog tsim ua ntej hauv pem teb, thiab lub voj voog puag ncig yog downward, thiab muaj qhov muag tsis pom kev. Nyob ib ncig ntawm nws, kom cov dej hauv av tsis tuaj yeem tuaj, thiab cov dej ntws tawm ib txwm dhau los ntawm qhov chaw ntawm cov kav dej ntws mus rau hauv cov qhov muag tsis pom ib puag ncig, thiab tom qab ntawd ntws mus rau hauv cov dej ntws los ntawm cov qhov muag tsis pom kev.
4) Sab hauv phab ntsa hauv qab daus yog dej-pov thawj, thiab cov kav dej tuaj yeem muab tso rau ntawm phab ntsa loj ntawm lub tsev, thiab lub rooj zaum puag ncig ntawm phab ntsa tseem ceeb.Ib txheej ntawm ib phab ntsa yog ua rau sab nraud ntawm cov kav dej los yog steel mesh hmoov cement yog siv los tiv thaiv lub rooj tsavxwm, kom qhov chaw ntawm cov dej ntws tawm sab nraud ntawm phab ntsa ntws ncaj nraim mus rau hauv qhov muag tsis pom kev mus txog rau lub pas dej.
5) Thaum muab cov kav dej tso rau hauv ib ntu, koj yuav tsum tau ua tib zoo saib: tsis txhob cia cov av, cement, daj xuab zeb thiab lwm yam khib nyiab nkag mus rau pem hauv ntej ntawm cov kav dej kom ntseeg tau tias qhov chaw ntawm cov kav dej tsis muaj kev cuam tshuam.
6) Siv cov kev tiv thaiv kom ntau li ntau tau thaum tso cov kav dej.Thaum muab cov kav dej tso rau hauv pem teb lossis chaw nres tsheb sab nraum zoov, qhov rov qab yuav tsum tau ua kom sai li sai tau kom tsis txhob muaj cua daj cua dub los ntawm kev ua kom lub qhov dej ntws tawm thiab cuam tshuam rau kev tso dej.Kev tiv thaiv dej hauv qab daus thiab phab ntsa sab hauv yuav tsum tau ua kom sai li sai tau txhawm rau tiv thaiv cov dej ntws los ntawm kev puas tsuaj los ntawm tib neeg lossis khoom.
7) Lub backfill yog cohesive av.Nws yog qhov zoo tshaj plaws rau nteg 3-5 cm ntawm cov xuab zeb daj ntawm geotextile, uas yog qhov zoo rau cov dej pom ntawm geotextile;yog hais tias lub backfill yog ib hom khoom noj khoom haus av los yog lub teeb av, tsis tas yuav nteg lwm txheej.Txheej ntawm cov xuab zeb daj, cov av nws tus kheej yog xoob heev thiab yooj yim rau lim dej.
8) Thaum tso cov kav dej, tom ntej no 1-2 fulcrums tuaj yeem muab tso rau ntawm sab thiab sab xis, lossis ob lub phaj hauv qab tuaj yeem ua raws, thiab sab saum toj yog overlapped nrog geotextiles.Tsuav tsis muaj av nkag mus rau hauv cov kav dej ntawm cov kav dej, nws txaus los ua kom cov dej ntws zoo.
