Xov xwm

Composite geomembrane yog dav siv hauv kwj dej seepage tiv thaiv engineering.Nyob rau hauv xyoo tas los no, kev siv dav thiab kev ua tau zoo ntawm cov ntaub ntawv geotechnical decomposition nyob rau hauv civil engineering, tshwj xeeb tshaj yog nyob rau hauv kev tswj dej nyab thiab kev cawm thaum muaj xwm txheej ceev, tau nyiam heev los ntawm lenient engineering technicians.Hais txog kev siv cov txheej txheem ntawm geotechnical decomposition cov ntaub ntawv, lub xeev tau npaj cov txheej txheem txheej txheem rau kev tiv thaiv seepage, filtration, drainage, reinforcement, thiab kev tiv thaiv, zoo heev accelerating kev nce qib thiab siv cov ntaub ntawv tshiab.Cov ntaub ntawv no tau siv dav hauv cov kav dej seepage tiv thaiv cov phiaj xwm hauv thaj chaw dej.Raws li txoj kev xav ntawm kev sib koom ua ke, daim ntawv no tham txog kev siv cov txheej txheem ntawm kev sib xyaw geomembrane.

Composite geomembrane yog ib qho kev sib xyaw geomembrane tsim los ntawm cua sov ib los yog ob sab ntawm daim nyias nyias nyob rau hauv ib qho chaw deb infrared qhov cub, nias lub geotextile thiab geomembrane ua ke los ntawm cov ntawv qhia cov menyuam.Nrog rau kev nce qib ntawm kev ua haujlwm thev naus laus zis, muaj lwm cov txheej txheem ntawm kev sib xyaw geomembrane.Qhov xwm txheej muaj xws li ib daim ntaub thiab ib zaj duab xis, ob daim ntaub thiab ib zaj duab xis, thiab ob zaj duab xis thiab ib daim ntaub.
Raws li cov txheej txheem tiv thaiv ntawm geomembrane, geotextile tiv thaiv cov txheej txheem tiv thaiv thiab impermeable los ntawm kev puas tsuaj.Txhawm rau txo cov hluav taws xob ultraviolet thiab ua kom muaj kev ua tau zoo, nws yog ib qho tsim nyog yuav tau txais cov txheej txheem embedding rau nteg.
Thaum lub sij hawm tsim kho, thawj zaug siv xuab zeb los yog av nplaum nrog ib lub cheeb ntawm cov khoom me me mus rau theem ntawm lub hauv paus nto, thiab ces nteg lub geomembrane.Lub geomembrane yuav tsum tsis txhob ncav nruj heev, nrog rau ob qho kawg faus rau hauv av nyob rau hauv ib tug corrugated zoo.Thaum kawg, siv cov xuab zeb zoo los yog av nplaum rau nteg ib txheej 10cm hloov pauv ntawm cov paved geomembrane.Tsim 20-30cm thaiv pob zeb (los yog precast qhob blocks) ua txheej tiv thaiv kev yaig.Thaum lub sij hawm tsim kho, kev siv zog yuav tsum tau ua los tiv thaiv pob zeb los ntawm kev tsis ncaj ncees los tsoo lub geomembrane, zoo dua txwv tsis pub siv cov ntaub thaiv npog thaum tso cov membrane.Kev sib txuas ntawm cov khoom sib xyaw geomembrane thiab cov qauv nyob ib puag ncig yuav tsum tau muab khi los ntawm cov hlua khi thiab cov hlaws hlau, thiab cov sib koom ua ke yuav tsum tau coated nrog emulsified asphalt (2 hli tuab) rau kev sib txuas kom tiv thaiv kom tsis txhob tawm.
Kev tsim kho xwm txheej
(1) Hom faus yuav tsum tau muab coj los siv: lub npog tuab yuav tsum tsis pub tsawg dua 30cm.
(2) Cov txheej txheem kho dua tshiab yuav tsum muaj cov cushion, anti-seepage txheej, hloov txheej, thiab cov ntaub thaiv npog.
(3) Cov av yuav tsum mos kom tiv thaiv kev sib haum xeeb tsis sib xws thiab tawg, thiab cov turf thiab tsob ntoo hauv paus hauv qhov tsis zoo yuav tsum raug tshem tawm.Muab cov xuab zeb los yog av nplaum nrog me me particle loj ua ib txheej tiv thaiv ntawm qhov chaw tiv thaiv daim nyias nyias.
(4) Thaum tso, lub geomembrane yuav tsum tsis txhob rub nruj heev.Nws yog qhov zoo dua rau embed ob qhov kawg hauv cov av hauv ib qho duab corrugated.Tsis tas li ntawd, thaum anchoring nrog cov ntaub ntawv nruj, qee qhov kev nthuav dav thiab kev cog lus yuav tsum tau tseg.
(5) Thaum lub sij hawm tsim kho, nws yog ib qho tsim nyog los tiv thaiv cov pob zeb thiab cov khoom hnyav los ntawm kev cuam tshuam ncaj qha rau ntawm geomembrane, kev tsim kho thaum tso cov membrane, thiab npog cov txheej txheem tiv thaiv.
