Rudzi rwepamusoro rwegumbeze rekudzivirira mvura ifirimu repamusoro-density polyethylene (HDPE) uye rezasi jira risiri rakarukwa. Iyo sodium bentonite isina mvura gumbeze ine nani isingapinde mvura inogadziriswa pakati pepamusoro-simba geotextiles uchishandisa yakakosha nzira yekubaya tsono uye wozoiswa pamucheka usina kurukwa. Mutsara wepamusoro-density polyethylene (HDPE) firimu inonamatira pairi. Bentonite isina mvura gumbeze ine simba rekudzivirira mvura uye rinopesana nepeji kupfuura rakajairwa bentonite isina mvura gumbeze. Nzira yekudzivirira mvura ndeyokuti bentonite particles inowedzera kana ichiiswa mumvura, ichigadzira yunifomu colloid system. Pasi pekudziviswa kwezvikamu zviviri zve geotextile, iyo bentonite inowedzera kubva pakusagadzikana kuenda kuhurongwa. Mhedzisiro yekuramba kunyura kwemvura uye kuwedzera ndeyekuita bentonite layer pachayo dense. , nokudaro kuva nesimba rekudzivirira mvura.
Mamiriro emuviri wegumbeze rakavharidzirwa risina mvura:
1. Iine unhu hwakanaka hwekudzivirira mvura uye hunopesana nekuona, iyo anti-seepage hydrostatic pressure inogona kusvika kupfuura 1.0MPa, uye chiyero chepermeability ndeye 5 × 10-9cm / s. Bentonite ndeye yakasikwa inorganic zvinhu izvo zvisingazoitike kuchembera uye zvine kunaka kusimba; uye hazvizoiti Chero kukanganisa kwakashata pane zvakatipoteredza chinhu chine hushamwari hwezvakatipoteredza
2. Iine maitiro ose ezvigadzirwa zve geotextile, zvakadai sekuparadzanisa, kusimbisa, kudzivirira, filtration, etc. Zviri nyore kuvaka uye hazvibvumirwi nekushisa kwemamiriro ekuvaka. Inogona zvakare kugadzirwa pazasi 0 ℃. Panguva yekuvaka, iwe unongoda kuisa GCL isina mvura gumbeze pasi pasi. Paunenge uchigadzira pafacade kana pamateru, gadzirisa nezvipikiri uye washer, uye uzviputire sezvinodiwa.
3. Easy kugadzirisa; kunyange mushure mekudzivirira kwemvura (seepage) kuvakwa kwapera, kana chivharo chekudzivirira mvura chikakuvadzwa netsaona, chero bedzi chikamu chakakanganisika chichingogadziriswa, kushanda kwakasimba kwekudzivirira mvura kunogona kuwanikwa zvakare.
4. Mutengo wekuita-mutengo wakanyanya kukwirira uye une huwandu hwakawanda hwekushandisa.
5. Iyo hupamhi hwechigadzirwa hunogona kusvika mamita matanhatu, iyo inofananidzwa nedzimwe nyika geotextile (membrane) tsanangudzo, inovandudza zvikuru kushanda kwekuvaka.
6. Inokodzera anti-seepage uye leakage kurapwa munzvimbo dzine yakakwirira yekudzivirira mvura uye anti-seepage zvinodiwa, senge tunnels, subways, dzimba dzepasi, pasi pevhu, zvivako zvakasiyana-siyana zvepasi pevhu uye mapurogiramu emvura ane hupfumi hwemvura yepasi.
