Siv high-density polyethylene li raw khoom, cov tav yog extruded los ntawm ib tug tshwj xeeb tshuab taub hau, thiab peb tav tav yog teem nyob rau hauv ib tug tej yam kev ncua deb thiab lub kaum sab xis los tsim ib tug peb-dimensional qhov chaw qauv nrog cov kua.Lub nruab nrab tav muaj ntau dua rigidity thiab tsim ib tug rectangular drainage channel.Peb txheej ntawm ribs uas ua rau cov kua dej network muaj siab ntsug thiab kab rov tav tensile zog thiab compressive zog.Cov kua dej tsim los ntawm peb txheej ntawm cov tav tsis yooj yim rau deform nyob rau hauv siab load, uas tuaj yeem tiv thaiv cov geotextile los ntawm kev kos rau hauv cov tub ntxhais geonet thiab xyuas kom cov kua dej du., Peb-dimensional geotechnical drainage network muaj lub zog muaj zog thiab kev ua haujlwm siab raws li lub hom phiaj.
Khoom Specifications
Mesh core thickness: 5mm ~ 8mm;dav 2 ~ 4m, ntev raws li cov neeg siv khoom xav tau.
Nta
1. Cov kua dej muaj zog (sib npaug rau ib meter tuab gravel drainage).
2. Lub zog tensile siab.
3. Txo qhov tshwm sim ntawm geotextiles embedded nyob rau hauv lub mesh core thiab tuav cov kua dej ruaj khov mus ntev.
4. Lub sij hawm ntev tiv taus siab load (tuaj yeem tiv taus compressive load li ntawm 3000Ka).
5. Corrosion kuj, acid thiab alkali tsis kam, kev pab lub neej ntev.
6. Kev tsim kho yog yooj yim, lub sij hawm tsim kho yog luv, thiab tus nqi txo.
Kev ua haujlwm tseem ceeb ntawm daim ntawv thov
1. Nws yog nteg nruab nrab ntawm lub hauv paus thiab sub-base kom ntws cov dej sib sau ntawm lub hauv paus thiab sub-base, thaiv cov dej capillary thiab zoo sib xyaw ua ke rau hauv ntug dej ntws.Cov qauv no cia li ua rau txoj kev ntws tawm ntawm lub hauv paus, lub sij hawm tso dej yog txo kom tsawg, thiab cov khoom siv hauv lub hauv paus yuav raug txo kom tsawg (piv txwv li, cov khoom siv nrog ntau nplua thiab qis permeability yuav siv tau).Txuas lub neej ntawm txoj kev.
2. Kev tso dej sib xyaw ua ke ntawm peb sab ntawm lub hauv paus tuaj yeem tiv thaiv cov khoom zoo ntawm lub hauv paus los ntawm kev nkag mus rau hauv lub hauv paus (uas yog, nws ua lub luag haujlwm ntawm kev sib cais).Lub hauv paus txheej txheej yuav nkag mus rau sab sauv ntawm lub geonet mus rau qhov txwv.Nws kuj tseem muaj peev xwm txwv qhov kev txav ntawm sab nraud ntawm lub hauv paus aggregate, nyob rau hauv txoj kev no nws ua zoo li lub zog ntawm geogrid.Feem ntau hais lus, lub zog tensile thiab rigidity ntawm peb-dimensional composite drainage net yog zoo dua li ntawm ntau geogrids siv rau lub hauv paus reinforcement, thiab qhov kev txwv no yuav txhim kho lub peev xwm ntawm lub hauv paus.
3. Tom qab txoj kev muaj hnub nyoog thiab cov kab nrib pleb tsim, feem ntau ntawm cov dej nag yuav nkag mus rau hauv seem.Nyob rau hauv cov ntaub ntawv no, peb-dimensional composite drainage net yog nteg ncaj qha nyob rau hauv txoj kev nto es tsis txhob ntawm cov kua hauv paus.Peb-dimensional composite ntws mesh tuaj yeem sau cov dej noo ua ntej nws nkag mus rau hauv lub hauv paus / subbase.Ntxiv mus, hauv qab kawg ntawm peb-dimensional composite drainage net yuav qhwv nrog ib txheej ntawm zaj duab xis ntxiv kom tsis txhob ya raws los ntawm kev nkag mus rau hauv lub hauv paus.Rau txoj kev nruj, cov qauv no tso cai rau txoj kev tsim nrog cov kua dej ntau dua Cd.Lwm qhov zoo ntawm cov qauv no yog qhov muaj peev xwm ntawm cov dej tsis sib xws ntawm cov pob zeb ua ke (kev tshawb fawb txog qhov txiaj ntsig ntawm qhov txiaj ntsig no tsis tu ncua).Txawm hais tias rau txoj kev nruj lossis kev hloov pauv txoj kev, cov qauv no tuaj yeem txuas ntxiv kev pabcuam lub neej ntawm txoj kev.
4. Nyob rau sab qaum teb huab cua, nteg ib qho kev sib xyaw ua ke ntawm peb-dimensional sib xyaw ua ke tuaj yeem pab txo qhov cuam tshuam ntawm cov dej khov heave.Yog hais tias lub freezing qhov tob tob, lub geonet yuav muab tso rau ntawm ib tug ntiav txoj hauj lwm nyob rau hauv lub sub-base ua raws li ib tug capillary blockage.Nws kuj yog ib qho tseem ceeb uas yuav tsum tau hloov nws nrog ib tug granular subbase uas tsis tshua muaj frosts heave, txuas mus rau lub freezing depths.Cov av backfill uas yooj yim rau Frost heave tuaj yeem ncaj qha sau rau ntawm peb-seem sib xyaw ua ke kom txog rau thaum cov kab hauv av.Hauv qhov no, lub kaw lus tuaj yeem txuas nrog lub qhov hluav taws xob kom lub rooj dej nyob ntawm lossis qis dua qhov tob no.Qhov no tuaj yeem txwv txoj kev loj hlob ntawm cov dej khov nab kuab yam tsis muaj kev txwv kev thauj mus los thaum cov dej khov yaj hauv lub caij nplooj ntoo hlav hauv thaj chaw txias.
Scope ntawm daim ntawv thov
Cov dej khib nyiab pov tseg, txoj kev loj subgrade thiab pavement drainage, railway drainage, tunnel drainage, underground structure drainage, retaining wall back drainage, garden and sports ground drainage.
Seams thiab laps
1. Kev hloov kho ntawm cov kev taw qhia ntawm cov khoom siv geosynthetic, ntsug yob ntev ntawm cov khoom yog nyob rau hauv txoj kev.
2. Kev sib xyaw geotechnical kua net yuav tsum tau txuas nrog cov geonet uas nyob ib sab, thiab cov tub ntxhais geosynthetic cov menyuam yuav tsum nyob ntawm qhov sib koom ua ke.
3. Cov xim dawb los yog daj ntawm cov yas buckle lossis polymer txuas nrog Hongxiang geomaterial ntim uas nyob ib sab ntawm cov tub ntxhais geonet, yog li txuas cov khoom yob.Txuas ib txoj siv txhua 3 ko taw raws qhov ntev ntawm cov khoom yob.
4. Overlapping fabrics thiab ntim nyob rau hauv tib txoj kev raws li stacking kev taw qhia.Yog hais tias lub geotextile nruab nrab ntawm lub hauv paus, lub hauv paus thiab sub-base yog nteg, nruam vuam, wedge welding los yog stitching yuav tsum tau nqa tawm mus ua.
Cov txheej geotextile tuaj yeem kho tau.Yog tias sutured, kev siv lub npog plooj lossis txoj kev suture yog pom zoo kom ua tiav qhov tsawg kawg nkaus lub voj voog ntev.
