Daim ntawv thov ntawm Filament Geotextiles hauv Railway Engineering

qhov paub dav tshaj plaws yog kev siv filament geotextile ntawm txoj kev loj.Qhov tseeb, nws kuj tau siv dav hauv railway engineering.Tsis tas li ntawd, filament geotextile cov ntaub ntawv yeej ib txwm paub zoo nyob rau hauv railway engineering daim ntaub ntawv.Qhov tshwj xeeb ntawm geotextile yuav tsum txiav txim siab ntawm qhov chaw, thiab qhov yuav tsum tau ua kom zoo yuav tsum tsis pub tsawg dua 200g / ㎡.Daim ntawv pov thawj xa khoom yuav tsum raug tshuaj xyuas.Lub geotextile yuav tsum tau xa mus rau hauv lub warehouse, thiab yuav tsum tsis txhob raug tshav ntuj nyob rau hauv qhib huab cua.Cov geotextile khaws cia rau ntau tshaj 6 lub hlis yuav tsum tsis txhob siv.Lub geotextile yuav tsum tsis muaj kev sib koom ua ke, thiab qhov ntev ntawm qhov sib tshooj yuav tsum tsis pub tsawg dua 1m.Qhov kev tso yuav tsum tiaj tus thiab ua kom zoo.Tom qab tso cov geotextile rau ntawm gravel txheej, xyuas seb lub puab tsaig yog tuab.Thaum pouring thiab tamping lub tiaj pob zeb cushion, tiv thaiv lub mortar los ntawm infiltrating mus rau hauv lub gravel txheej.Thaum lub sij hawm pouring thiab tamping ntawm berth slab, xyuas cov kav dej ntws los ntawm seem.Dredge thiab tshem tawm sundries txhua lub sijhawm.Filament geotextile yeej ib txwm yog peb cov khoom siv hauv cov dej tsis zoo thiab cov dej tsis zoo, vim tias nws yog ib qho permeable geosynthetics ua los ntawm hluavtaws fibers los ntawm koob xuas nrig ntaus los yog xaws.
Cov khoom tiav yog nyob rau hauv daim ntawv ntawm daim ntaub, nrog ib tug dav dav ntawm 2-6.2 meters thiab ib tug luj ntawm 180-670 g / ㎡.Nyob rau tib lub sijhawm, nws muaj kev lim dej zoo heev, kev sib cais, kev txhawb nqa thiab kev tiv thaiv, siab tensile lub zog, zoo permeability, kub tsis kam, khov tsis kam, laus tiv taus, corrosion kuj thiab lwm yam kev ua tau zoo.Tsis tas li ntawd, cov filament geotextile nws tus kheej muaj cov ntaub ntawv zoo thiab adhesion zoo, Raws li cov fiber ntau yog mos, nws muaj qee yam kua muag tsis kam, tiv thaiv cov membrane quab yuam thiab zoo deformation adaptability, nrog rau cov dav hlau ntws zoo.Qhov chaw mos nrog ntau qhov sib txawv muaj qhov sib txhuam zoo sib xws, uas tuaj yeem ua rau kom cov adhesion ntawm cov av, tiv thaiv kev poob ntawm cov khoom zoo thiab tshem tawm cov dej ntau dhau tib lub sijhawm.Lub ntsej muag muag muaj peev xwm tiv thaiv zoo.Yog li ntawd, cov filament geotextile tau siv dav hauv kev tsheb ciav hlau engineering, thiab tau ua tiav cov txiaj ntsig ntawm kev txo nqi thiab zoo dua.Nyob rau hauv xyoo tas los no, filament geotextile yog ib qho ntawm cov khoom siv high-end tsim los ntawm cov khoom siv polyester ntshiab.Nws yog siv thiab tsim ua raws li cov kev xav tau ntawm railway engineering, thiab cov txiaj ntsig tau lees paub raws li kev siv mus ntev.Txij li thaum txoj kev loj hlob ntawm railway engineering nrog filament geotextile, Tuam Tshoj txoj kev tsheb ciav hlau kev lag luam tau tsim nyob rau hauv kev kub ceev.Kev kub ceev railway siv ib qho ntawm cov ntaub ntawv tseem ceeb hauv impermeable thiab waterproof geotextiles.
