Iyo yepamusoro yegumbeze-yakavharwa-yakavharwa mvura yegumbeze ifirimu repamusoro-density polyethylene (HDPE), uye rezasi jira risiri rakarukwa. Imwe firimu repamusoro-density polyethylene (HDPE) inonamirwa pairi. Bentonite isina mvura gumbeze ine simba risingapinde mvura uye rinopesana nepeji kugona kupfuura rakajairwa bentonite isina mvura gumbeze. Nzira yekudzivirira mvura ndeyokuti bentonite particles inoputika nemvura kuti iite yunifomu colloidal system. Pasi pekudziviswa kwezvikamu zviviri zve geotextiles, iyo bentonite inowedzera kubva pakusagadzikana kuenda kuhurongwa. Mhedzisiro yekuramba kunyura kwemvura uye kuwedzera ndeyekuita bentonite layer pachayo dense. , kuitira kuti isapinda mvura.
Mamiriro emuviri webhaisikopo rakavharwa negumbeze remvura:
1. Iyo ine yakanakisa kusapinda kwemvura uye inopesana-seepage performance, iyo anti-seepage hydrostatic pressure inogona kusvika kupfuura 1.0MPa, uye permeability coefficient ndeye 5 × 10-9cm / s. Bentonite ndeye yakasikwa inorganic material, iyo isingazoiti kuchembera maitiro uye ine yakanaka durability; Chero kukanganisa kwakashata pane zvakatipoteredza chinhu chinochengetedza zvakatipoteredza
2. Iine maitiro ose ezvigadzirwa zve geotextile, zvakadai sekuparadzanisa, kusimbisa, kudzivirira, filtration, nezvimwewo. Kuvaka kuri nyore uye hakurevi nekupisa kwemamiriro ekuvaka, uye inogonawo kuvakwa pasi pe0 ° C. Panguva yekuvaka, ingoisa GCL jira risingapindi mvura pasi, gadzirisa nezvipikiri uye washer paunenge uchigadzira pafacade kana pamateru, uye woiputira sezvinodiwa.
3. Easy kugadzirisa; kunyange mushure mekuvhara kwemvura (seepage) kuvakwa kwapera, kana jira rekudzivirira mvura rakakuvadzwa netsaona, chero bedzi chikamu chakakanganisika chichingogadziriswa, kushanda kwemvura kunogona kuwanikwa zvakare sezvazvaive.
4. Mutengo wekuita-mutengo wakanyanya kukwirira, uye kushandiswa kwakakura kwazvo.
5. Upamhi hwechigadzirwa hunogona kusvika mamita matanhatu, iyo inofananidzwa nemirairo yepasi rose geotextile (membrane), iyo inovandudza zvikuru kubudirira kwekuvaka.
6. Inokodzera kupikisa-seepage uye anti-seepage kurapwa muminda yepamusoro-soro yemvura uye inopesana-seepage zvinodiwa, zvakadai se: tunnels, subways, dzimba dzepasi, nzira dzepasi pevhu, zvivako zvakasiyana-siyana zvepasi pevhu uye mapurojekiti emvura ane mvura yakawanda yepasi.
