Geotextile yog cov khoom xav tau thiab nrov heev uas tau siv zog ua haujlwm hauv kev lag luam thiab kev tsim kho. Feem ntau nws yog siv rau hauv cov txheej txheem ntawm kev tsim tsev, thaum cov dej hauv av nyob rau theem siab, ua rau muaj kev xav tau ntawm cov kav dej.
Nyob rau hauv cov ntaub ntawv no, nws yog ib qho tseem ceeb heev uas yuav tau xaiv cov ntaub ntawv zoo, vim hais tias lub functionality ntawm lub system thiab cov kev pab cuam lub neej ntawm lub hauv paus thiab lub tsev nws tus kheej ncaj qha nyob ntawm qhov no. Yog li no, niaj hnub no peb yuav txiav txim siab seb hom geotextile rau cov kua dej yog dab tsi, yuav ua li cas xaiv, qhov ceev ntawm cov khoom no tuaj yeem muaj thiab nws cov yam ntxwv tseem ceeb yog dab tsi.
Dab tsi yog geofabric
Geofabric yog cov ntaub tsis-woven tau los ntawm kev sib txuas lossis thermal bonding.
Nyob rau hauv thawj qhov sib txawv, ib daim ntaub uas tsis tshua muaj hygroscopic tsis tau, yog li cov khoom silts sai heev, uas yog kiag li tsis txaus ntseeg nyob rau hauv tej rooj plaub.
Cov ntaub sov yog nyias heevmuaj zog txaus thiab ruaj khov.
Lub hom phiaj tseem ceeb ntawm geofabric yog txhawm rau txuas lub neej ntawm cov tshuab nruab rau cov dej hauv av los ntawm lub hauv paus. Txawm li cas los xij, vim nws cov khoom tshwj xeeb, cov khoom no tau dhau los ua neeg thoob ntiaj teb thiab tau txais txiaj ntsig zoo hauv ntau qhov chaw ntawm lub neej.
Cov txiaj ntsig Geofabric
Piv nrog rau lwm cov ntaub ntawv, geofabric muaj ntau qhov zoo. Namely:
1. kiag li tsis nqus noo noo. Dhau kua los ntawm nws tus kheej, sifting tawm me me thiab ntau yam impurities.
2. Nws yog tus cwj pwm los ntawm qib siab ntawm vapor permeability, tso cai rau huab cua hloov pauv hauv cov kua dej.
3. Durable. Yuav tsis delaminate, yob lossis rot.
4. Resistant kub thiab hluav taws kub. Qhov zoo no tsis yog tsuas yog ua kom muaj kev nyab xeeb ntawm hluav taws, tab sis kuj tiv thaiv av thiab huab cua paug los ntawm cov khoom phom sij uas txhua yam khoom siv hluav taws xob tawm thaum lub sij hawm combustion.
5. Tsis raug rau colonization los ntawm cov kab mob thiab lwj.
6. Nws tsis ua rau muaj teeb meem thaum lub sij hawm xa khoom thiab kev teeb tsa. Compact rolls muab kev thauj mus los yooj yim thiab yooj yim khaws cov khoom yuav khoom. Tso lub canvas yooj yim heev thiab tsis tas yuav muaj kev koom tes ntawm cov kws tshaj lij tsim nyog.
7. Ua kom muaj kev ncaj ncees tag nrho ntawm cov qauv thiab cov tshuab, ua kom lawv cov kabmob muaj peev xwm.
8. Nws muaj lub neej ua haujlwm ntev. Tsis tas yuav hloov pauv txawm tias tom qab siv txuas ntxiv.
Sphereapps
Geofabric rau cov kua dej tau nquag siv thaum lub sijhawm tso thiab kho txoj kev, txhawm rau ntxiv dag zog rau cov slopes thiab tso cov kav dej hauv av.
Cov khoom siv kuj tau siv dav hauv kev tsim kho ntiag tug. Nyob rau hauv tus txheej txheem ntawm nteg nkag mus rau hauv txoj kev, nws yog siv raws li ib tug reinforcing txheej, uas yog pw nyob rau hauv lub gravel.
Tsis tas li ntawd, geotextiles rau cov kua dej, cov yam ntxwv ntawm cov uas tau tham hauv kab lus no, feem ntau siv rau hauv kev tsim toj roob hauv pes. Piv txwv li, nyob rau hauv tus txheej txheem ntawm kev npaj cov av dag, nws yog nteg nyob rau hauv lub hauv av nyob rau hauv thiaj li yuav tiv thaiv cov qauv ntawm lub reservoir los ntawm kev puas tsuaj los ntawm tsob ntoo keeb kwm. Feem ntau, cov pob zeb nyob ze dej tau ntxiv dag zog nrog cov khoom siv no txhawm rau tiv thaiv lawv ntawm kev puas tsuaj thiab pw tsaug zog nrog av.
Basic zog ntawm geotextile
Vim nws cov yam ntxwv tshwj xeeb, geofabric rau cov kua dej (tus nqi uas nyob ntawm cov yam ntxwv ntawm cov khoom) tau nquag siv hauv kev kho thiab kev tsim kho kev lag luam, qhov twg nws tuaj yeem ua raws li:
• faib cov khoom (cais nyias txheej ntawm av thiab crushed pob zeb nyob rau hauv lub trench);
• fasteners (xa tawm lub nra ntawm thaj chaw loj);
• lim (tiv thaiv pob zeb thiab pob zeb sib xyaw nrog av);
• tiv thaiv (tsis pub kom av sag);
• kua (cua cov khoom hauv dej, tiv thaiv kom tsis txhob nkag mus rau hauv cov kav dej).
Tim cov ntaub ntub dej
Geotextiles tau muab faib ua ntau hom raws li kev tsim khoom:
• Polypropylene thiabpolyester ntaub. Hom no suav hais tias yog qhov zoo tshaj plaws thiab ruaj khov. Cais, nws yuav tsum tau hais tias polypropylene fibers yuav siv tau nyob rau hauv tej yam kev mob, thiab polyester ntaub tsis txais kev sib cuag nrog cov dej ntau, vim nws maj mam dhau noo noo los ntawm nws tus kheej.
• Monofilament khoom. Hom geofabric no nyob rau hauv tsis muaj txoj hauv kev ua tsis tau zoo rau yav dhau los version thiab suav tias yog qhov tsim nyog tshaj plaws rau kev npaj cov kua dej.
• Cov ntaub los ntawm cov ntaub ntawv pov tseg. Cov khoom no yog tsim los ntawm paj rwb thiab ntaub plaub fibers. Txij li cov khoom tseem ceeb ntawm cov ntaub yog qhov muaj feem cuam tshuam rau kev lwj, qhov kev txwv ntawm hom no yog qhov tsawg heev. Rau kev teeb tsa ntawm cov kav dej, qhov ntau yam no tsis siv txhua.
Cov yam ntxwv tseem ceeb ntawm geotextile
Qhov zoo ntawm geofabric rau cov kua dej suav nrog:
• hygroscopicity;
• zog;
• smoothness.
Qhov tseem ceeb tshaj plaws los ntawm kev xaiv cov dej geofabric yog qhov ntom. Qhov kev ntsuas no qhia txog cov khoom tseem ceeb ntawm cov khoom.
Qhov ntom yog txiav txim siab raws li qhov hnyav ntawm cov khoom. Yog li, qhov ntau dua qhov hnyav ntawm ib square meter ntawm ntaub, qhov siab dua nws qhov ntom. Txawm li cas los xij, qhov no tsis tau txhais hais tias qhov kev xaiv hnyav tshaj plaws yuav tsum nyiam thaum xaiv cov khoom siv, vim tias qhov ntom ntom ntawm cov ntaub ntau dua, nws cov peev xwm pom tau qis dua.
Lub zog siab ntawm cov hniav tso cai rau nws tiv taus cov khoom thauj mus txog250 kg. Nyob rau hauv cov ntaub ntawv no, nws yuav tsum tau muab coj mus rau hauv tus account hais tias lub zog mechanical zog ntawm cov khoom ntau dua, nws lub peev xwm culvert qis dua.
Kev saib xyuas tshwj xeeb yuav tsum tau them rau qhov coefficient ntawm kev lim dej. Nws qhia tias cov kua dej ntau npaum li cas tuaj yeem lim hauv 24 teev. Qhov ntsuas no kuj ncaj qha ntsig txog qhov ntom ntawm cov ntaub.
Yuav ua li cas xaiv qhov geotextile ceev
Tam sim no cia saib seb koj yuav tsum paub dab tsi thaum yuav geotextiles rau cov kua dej. Yuav xaiv cov khoom siv zoo li cas yog thawj lo lus nug uas txhawj xeeb rau cov neeg uas tab tom yuav teeb tsa cov kav dej.
Rau lub hom phiaj no, nws yog ib qho tsim nyog xaiv cov khoom uas muaj qee yam yam ntxwv.
Cov canvas yuav tsum txaus elastic, nruj, ntxeem tau thiab, tau kawg, lav qhov kev tiv thaiv ntawm cov kua dej hauv cov av shrinkage. Tsuas yog cov khoom zoo li no tuaj yeem muab cov dej noo kom tiav.
Thaum xaiv ib lub geofabric rau cov kua dej, qhov kev nyiam yuav tsum tau muab rau cov kev xaiv uas nws qhov ceev sib txawv ntawm 200-300 grams ib 1 cubic meter.
Yog tias koj tab tom npaj cov kua hauv av ib txwm los ntawm qhov chaw, koj tuaj yeem tau txais los ntawm cov ntaub uas nws qhov ceev yog 100 grams ib cubic meter. Tib qhov ntom yog siv hauv kev tsim kho kom zoo nkauj.
Rau paving thiab lwm hom kev ua haujlwm, geotextiles nrog qhov ntom ntawm yam tsawg 800 grams ib cubic meter yuav tsum raug xaiv.
Rau qhov kev teeb tsa ntawm cov dej ntws, geotextiles ua los ntawm monofilaments yog siv. Tsis tas li rau cov hom phiaj no, koj tuaj yeem siv cov khoom tau los ntawm kev kho cua sov.
Geocomposite fibers yog siv rau hauv thaj chaw ntawm marsh keeb kwm. Qhov ceev ntawm cov khoom no yuav tsum yog 150-200 grams ib cubic meter.
Cov ntaub ntawv koob-punched tau txhaws nrog cov xuab zeb sai heev, yog li lawv tau xyaum tsis siv los npaj cov kua dej.
Koj yuav tsum tau them sai sai rau qhov dav ntawm geo-web, vim qhov loj ntawm qhov kev pab cuam yav tom ntej nyob ntawm qhov ntsuas no. Niaj hnub no geofabric rau cov kua dej muaj nyob rau hauv dav ntawm ob mus rau tsib meters.
Tus nqi
Tej zaum, ntau tus txhawj xeeb txog cov lus nug: "Puas yog geofabric rau cov nqi ntws?" Tus nqi ib m2 nyob ntawm qhov ntom ntawm cov khoom thiab nws yuav ua li cas.
Yog li, koob-punched geofabric yuav raug nqi tus neeg yuav khoom los ntawm 25 txog 70 rubles ib square meter. Tus nqi ntawm cov canvases npaj rau pouring lub hauv paus nyob ntawm qhov ntom ntawm cov khoom - qhov siab dua, cov khoom kim dua.
Tus nqi ib square meter ntawm cov khoom woven yog khaws cia li ntawm 30 rubles.
Cov kav dej nrog geotextile yuav raug nqi txog 3,500 rubles rau pob 50-meter.
Thaum xaiv cov khoom tsim nyog, koj yuav tsum muab qhov nyiam rau cov khoom uas yog tsim los ntawm cov tuam txhab muaj npe nrov. Tom qab tag nrho, tsuas yog high-zoo geotextiles yuav tiv thaiv yaig thiab heaving.av, ntxiv dag zog rau lub hauv paus thiab ua kom cov kua dej zoo meej. Yog li ntawd, koj yuav tsum tsis txhob txuag ntawm cov khoom siv no, tshwj xeeb tshaj yog vim nws qhov kev yuav khoom yuav tsis ua rau tus nqi siab.
