Cov yam ntxwv ntawm geotextile rau pob zeb tawg thiab nws tso yog cov ntsiab lus tseem ceeb heev rau kev npaj txhua lub vaj vaj, thaj tsam hauv zos (thiab tsis yog nkaus xwb). Nws yog qhov tsim nyog kom nkag siab meej vim li cas koj thiaj li yuav tsum tso nws nruab nrab ntawm cov xuab zeb thiab pob zeb. Nws kuj tseem tsim nyog xam tawm qhov twg geotextile yog qhov zoo tshaj plaws siv rau txoj kev hauv vaj.

Nws yog dab tsi thiab nws yog dab tsi rau?

Lawv tau sim ua kom nteg geotextiles nyob rau hauv pob zeb tawg tau ntev heev. Thiab qhov kev daws teeb meem thev naus laus zis no ua rau nws tus kheej feem ntau. Nws nyuaj txawm xav txog qhov xwm txheej thaum nws yuav tsis haum. Geotextile yog ib qho ntawm ntau yam ntawm qhov hu ua geosynthetic canvas . Nws tuaj yeem tau txais los ntawm ob txoj kev woven thiab tsis-txheej txheem.

Thauj khoom rau 1 sq. m tuaj yeem ncav cuag 1000 kilonewtons. Qhov ntsuas no txaus txaus kom ntseeg tau tus yam ntxwv tsim qauv. Kev tsim cov ntawv geotextiles hauv cov pob zeb tawg yog qhov tsim nyog rau ntau qhov chaw tsim kho, suav nrog kev tsim cov tsev, txoj hauv kev. Geotextiles rau txoj kev rau ntau lub hom phiaj tau siv dav. Nws lub luag haujlwm tseem ceeb:

• nce peev txheej peev txheej tag nrho;
• txo tus nqi ntawm kev ua haujlwm;
• nce lub zog ntawm cov txheej txhawb ntawm cov av.

Nrog rau qib thev naus laus zis tam sim no, nws tsis tuaj yeem nrhiav lwm txoj hauv kev rau cov khoom siv geological rau tag nrho cov txiaj ntsig ntawm lawv cov yam ntxwv . Cov khoom siv no tau ua pov thawj nws tus kheej kom zoo tshaj plaws hauv kev coj ua hauv tsev, qhov twg muaj pes tsawg qhov teeb meem av yog qhov loj heev. Lub luag haujlwm tseem ceeb tshaj plaws ntawm geotextiles yog kev tiv thaiv kom khov. Nws tau pom tias kev siv cov ntaub ntawv no raug tuaj yeem ua rau kev pab cuam lub neej ntawm txoj kev los ntawm 150% thaum txo tus nqi ntawm cov khoom siv hauv tsev.

Hauv tsev, geotextiles feem ntau yog muab tso nruab nrab ntawm cov xuab zeb thiab pob zeb txhawm rau txhawm rau tshem tawm kev cog qoob loo ntawm cov nyom.

Kev piav qhia ntawm hom

Non-woven hom geotextile yog tsim los ntawm polypropylene lossis polyester fibers. Qee zaum, lawv tau sib xyaw nrog cov xov tsim los ntawm cov khoom siv raw. Geofabric tau yooj yim los ntawm kev xaws xov. Qee zaum kuj tseem muaj cov khoom siv xaws, hu ua geotricot, nws txoj kev siv dav tau cuam tshuam los ntawm qhov nyuaj ntawm cov thev naus laus zis siv. Rau koj cov ntaub ntawv: tsis-woven polypropylene tsim nyob rau hauv Russia, ua los ntawm cov txheej txheem xuas nrig ntaus, muaj lub npe lag luam "dornit", nws tuaj yeem tso tau yam xyuam xim tso rau hauv qab zeb.

Rau kev tsim cov ntawv geological, ntxiv rau polypropylene, lawv tuaj yeem siv:

• polyester;
• aramid fiber ntau;
• ntau hom polyethylene;
• iav fiber ntau;
• basalt fiber ntau.

Cov Lus Qhia Xaiv

Hais txog lub zog, polypropylene sawv tawm zoo. Nws tsis tiv taus rau yam tsis zoo ib puag ncig thiab tuaj yeem tiv taus lub zog muaj zog . Nws tseem yog qhov tseem ceeb heev los xaiv qhov ntom ntom. Cov khoom siv nrog lub ntiajteb txawj nqus tshwj xeeb los ntawm 0.02 txog 0.03 kg rau 1 m2 tsis haum rau tso hauv qab pob zeb. Nws qhov chaw tseem ceeb ntawm daim ntawv thov yog kev tiv thaiv kev pecking ntawm cov noob los ntawm cov noog, txheej txheej los ntawm 0.04 txog 0.06 kg kuj tseem xav tau tshwj xeeb hauv kev cog qoob loo thiab cog qoob loo.

Hauv qab txoj kev hauv vaj, koj tuaj yeem thov txheej txheej ntawm 0.1 kg rau 1 m2 . Nws kuj tseem siv ua lub lim dej geomembrane. Thiab yog tias qhov ntom ntom ntawm cov khoom yog los ntawm 0.25 kg rau 1 m2, tom qab ntawd nws tuaj yeem muaj txiaj ntsig zoo rau kev npaj cov neeg taug kev. Yog tias qhov ntsuas tsis tau ntawm lub vev xaib nyob rau hauv pem hauv ntej, yuav tsum xaiv qhov koob txhaj tshuaj.

Kev siv cov canvas yog nyob ntawm qhov teeb meem uas lawv npaj yuav daws.

Yuav ua li cas pawg?

Geotextiles tuaj yeem tsuas yog tso rau ntawm qhov tiaj tiaj. Yav dhau los, txhua qhov protrusions thiab grooves raug tshem tawm ntawm nws. Ntxiv:

• maj mam ncab daim ntaub nws tus kheej;
• kis nws nyob rau hauv lub dav hlau dav lossis hla hla tag nrho saum npoo;
• muab nws tso rau hauv av siv tshwj xeeb thauj tog rau nkoj;
• qib txheej;
• raws li thev naus laus zis, lawv qib, ncab thiab koom nrog cov canvas uas nyob ib sab;
• ua qhov sib tshooj ntawm cov canvas ntawm thaj chaw loj los ntawm 0.3 m;
• xa cov khoom tawg uas nyob ib sab los ntawm kev ua ntawv xaus-rau-kawg lossis kho cua sov;
• xaiv pob zeb tawg yog nchuav, ua kom haum rau qib uas xav tau.

Kev txhim kho kom raug yog qhov kev lees paub ntawm kev tiv thaiv zoo tiv thaiv qhov tsis zoo . Tsis txhob tso me me ntawm cov hauv paus hniav lossis pebbles hauv av, nrog rau qhov. Cov txheej txheem txheej txheem ua haujlwm xav tias cov tub ntxhais tau muab tso los ntawm sab hauv qab, thiab cov geotextile ib txwm - los ntawm sab uas xav tau, tab sis nws yog tib yam uas cov yob yuav tsum tau muab kauv raws txoj kev. Yog tias koj sim siv lawv rau txoj hauv kev ua vaj pob zeb yam tsis tau tawm, "nthwv dej" thiab "quav" yuav luag tsis pom. Ntawm qhov tiaj tiaj tiaj, qhov sib tshooj yog 100-200 hli, tab sis yog tias nws tsis tuaj yeem ua kom zoo ib yam, tom qab ntawd 300-500 hli.

Thaum tsim txoj kev sib koom ua ke, nws yog qhov ib txwm muab tso rau hauv daim duab tom ntej hauv qab no, tom qab ntawd tsis muaj dab tsi yuav txav thaum lub sijhawm ua tiav . Dornit cov hlua tau koom nrog kev pab ntawm cov thauj tog rau nkoj zoo li daim ntawv P. Tom qab ntawd lawv sau rau hauv cov pob zeb tawg uas siv lub tsheb nrau av (hauv qhov me me - ntawm tus kheej). Cov txheej txheem yog yooj yim heev.

Txawm li cas los xij, nws yog ib qho tsim nyog kom tsis txhob muaj qhov ncaj qha hla lub geotextile, thiab tom qab ntawd ua tib zoo ntsuas qib cov khoom pov tseg thiab ua kom nws nruj.
