Iindaba

I-Geomembrane yenziwe ngefilimu yeplastiki njenge-anti-seepage substrate kunye ne-non-loven fabric composite. Ukusebenza kwe-anti-seepage ye-geomembrane ikakhulu kuxhomekeke ekusebenzeni kwe-anti-seepage yefilimu yeplastiki. Iifilimu zeplastiki ezisetyenziselwa ukuchasana nokubona iphepha ngaphakathi nangaphandle ikakhulu ziquka i-polyvinyl chloride, i-polyethylene, kunye ne-ethylene/vinyl acetate copolymers. Yimathiriyeli yeekhemikhali yepolymer eguquguqukayo kunye nenxalenye encinci, i-ductility eyomeleleyo, ukuguquguquka okuqinileyo, ukumelana nokugqwala, ukumelana nobushushu obuphantsi, kunye nokuxhathisa okuhle kweqabaka. Okwesibini, imisebenzi ephambili kunye nokusetyenziswa kwefilimu yeplastiki yaziswa.
Imisebenzi ephambili
Nye. Idibanisa imisebenzi ye-anti-seepage kunye ne-drainage, kwaye inemisebenzi yodwa kunye nokuqiniswa.
2. Amandla aphezulu adityanisiweyo, amandla aphezulu e-peel, kunye nokumelana nokugqobhoza okuphezulu.
Ntathu. Umthamo oqinileyo wokukhupha amanzi, i-coefficient ephezulu yokukhuhlana, kunye ne-coefficient yokwandiswa komgca ophantsi.
4. Ukumelana nokuguga okuhle, uluhlu olubanzi lobushushu, kunye nomgangatho ozinzile.

I-composite geomembrane yimathiriyeli ye-geotextile anti-seepage eyenziwe ngefilimu yeplastiki njenge-anti-seepage substrate kunye nelaphu elingalukwanga. Ukusebenza kwayo okuchasene ne-seepage ikakhulu kuxhomekeke ekusebenzeni kwe-anti-seepage yefilimu yeplastiki. Iifilimu zeplastiki ezisetyenziselwa ukusetyenziswa kwe-anti-seepage izicelo zombini ngaphakathi nangaphandle ngokubanzi ziquka i-polyvinyl chloride (PVC), i-polyethylene (PE), kunye ne-ethylene / vinyl acetate copolymer (EVA). Ziluhlobo lwezinto eziguquguqukayo zeekhemikhali zepolymer ezinobunzima obuthile obuphantsi, ukolula olomeleleyo, ukuguquguquka okuphezulu kwi-deformation, ukumelana nokugqwala, ukumelana nobushushu obuphantsi, kunye nokuxhathisa okuhle kweqabaka.

Ubomi benkonzo ye-geomembranes edibeneyo inqunywe ngokukodwa ukuba ifilimu yeplastiki ilahlekelwa yi-anti-seepage kunye neendawo ezichasene namanzi. Ngokwemigangatho yelizwe laseSoviet, iifilimu ze-polyethylene ezinobunzima be-0.2m kunye nezizinzi ezisetyenziselwa ubunjineli bamanzi zingasebenza iminyaka engama-40-50 phantsi kweemeko zamanzi acacileyo kunye neminyaka engama-30-40 phantsi kweemeko zamanzi amdaka. Ngoko ke, ubomi benkonzo ye-geomembrane edibeneyo yanele ukuhlangabezana neemfuno ezichasene ne-seepage zedama.
Umda we-geomembrane
Idama lokuqala laliludonga olungundoqo, kodwa ngenxa yokudilika kwedama, indawo engaphezulu yodonga olungundoqo iye yaqhawulwa. Ukusombulula ingxaki ye-anti-seepage ephezulu, i-anti-seepage inclined wall yongezwa ekuqaleni. Ngokovavanyo lokhuseleko kunye nohlalutyo lwedama laseZhoutou Reservoir, ukuze kusonjululwe ukuvuza okubuthathaka komphezulu kunye nokuvuza kwesiseko sedama okubangelwa kukudilika komhlaba okuninzi kwedama, amanyathelo okuthintela ukutyhutyha okuthe nkqo okufana nokugrumba kwebhedi, ukugrunjwa komphezulu, ukugungxulwa kunye nokugungxulwa. umkhono wokubamba kakuhle umkhusane wokuzalisa umva, kunye nodonga lwepleyiti yokutshiza yoxinzelelo oluphezulu olwamkelwayo. Udonga oluphezulu oluthambekele lugqunywe nge-geomembrane ehlanganisiweyo ye-anti-seepage, kwaye iqhagamshelwe kudonga oluthe nkqo oluchasene ne-seepage ezantsi, lufikelela kumphakamo we-358.0m (0.97m ngaphezu komgangatho wesikhukula sokutshekisha)
umsebenzi omkhulu
1. Ukudibanisa imisebenzi ye-anti-seepage kunye ne-drainage, ngelixa ikwanemisebenzi efana nokuhlukaniswa kunye nokuqinisa.
2. Amandla aphezulu adityanisiweyo, amandla aphezulu e-peel, kunye nokumelana nokugqobhoza okuphezulu.
3. Umthamo oqinileyo wokukhupha amanzi, i-coefficient ephezulu ye-friction, kunye ne-coefficient yokwandisa umgca ophantsi.
4. Ukumelana nokuguga okuhle, ukuguquguquka okubanzi kuluhlu lobushushu bendalo, kunye nomgangatho ozinzile.
