Mambure emvura akagadzirwa necomposite zvinhu zvinowanzoshandiswa mumarara, migwagwa, madziro emukati memugero nemamwe mapurojekiti. Saka, ndezvipi zvikamu zvemambure emvura akagadzirwa necomposite?
Mambure ekudhonza mvura akagadzirwa nesimbi yepurasitiki ine mativi matatu uye geotextile inopindika ine mativi maviri. Musanganiswa uyu haungopi chete simba rakasimba rekudhonza mvura, asiwo unoita kuti ive nezvakanaka zvekusimba kwakanyanya kwekudhonza, kuramba ngura uye kugara kwenguva refu.
1. Chitubu chepurasitiki ndicho chinhu chikuru chemumbure wekudhonza mvura wakabatana. Chakagadzirwa nepolyethylene ine density yakakwira (HDPE) uye chinogadziriswa nenzira yekuumba mvura yakasarudzika. Chitubu ichi chepurasitiki chine chimiro chakasarudzika chine mativi matatu. Mbabvu dzepakati dzakasimba uye dzakarongwa kwenguva refu kuti dzigadzire mugero wekudhonza mvura; mbabvu dzakarongwa dzichikwira nekudzika dzinoumba rutsigiro rwekudzivirira geotextile kuti isapinzwe mugero wekudhonza mvura. Kunyangwe kana paine mitoro yakawanda, chitubu chepurasitiki chinogona kuchengetedza kushanda kwakakwirira kwekudhonza mvura. Simba rekudhonza uye rekutenderera repakati pepurasitiki rakakwirira, izvo zvinogona kuve nechokwadi chekugadzikana uye kuvimbika kwemumbure wekudhonza mvura wakabatana panguva yekushandiswa kwenguva refu.
2. Geotextile inoyerera mvura chimwe chinhu chakakosha checomposite drainage net. Inowanzo shandisa zvinhu zvakaita sejira repolyester filament, jira repolyester staple fiber kana jira repolypropylene staple fiber. Basa guru regeotextile nderekusefa tsvina, kuona kuti core yenet inofamba zvakanaka, uye kubvisa mvura nenguva. Geotextile inogonawo kusungirirwa zvakasimba necore yepurasitiki kuti igadzire chimiro chedrainage chakabatanidzwa, izvo zvinogona kuvandudza mashandiro edrainage nehupenyu hwebasa recomposite drainage net.
3. Kuwedzera kune zvikamu zviviri zvikuru zvataurwa pamusoro apa, mambure ekudhonza mvura akagadzirwa necomposite anogonawo kugadziriswa zvichienderana nezvinodiwa nevatengi panguva yekugadzira. Semuenzaniso, geotextile yakasanganiswa kumativi ese inogona kunge iri jira refilament, jira pfupi refilament, jira regirini kana jira dema. Kuchinjika uku kunobvumira mambure ekudhonza mvura akagadzirwa necomposite kuti agadzirise zviri nani zvinodiwa nemapurojekiti akasiyana uye kuvandudza mashandiro ese uye mabhenefiti epurojekiti.
Mambure ekudhonza mvura akabatanidzwa anogona kushandiswa munzvimbo dzakawanda dzakadai senzvimbo dzekurasira marara, mipata yemigwagwa, uye madziro emukati memugero. Haangogoni chete kudhonza mvura yakaungana pakati pehwaro nepasi pevhu, kuvhara mvura ye capillary, asiwo kuvandudza simba rekutsigira hwaro uye kuwedzera hupenyu hwebasa remugwagwa. Uyezve, ine zvakanakira zvekuvaka zviri nyore, nguva pfupi yekuvaka uye kuderedzwa kwemari.
Sezvatinoona kubva pamusoro apa, mambure ekudhonza mvura akagadzirwa nezvinhu zviviri: simbi yepurasitiki ine mativi matatu uye geotextile inopindika ine mativi maviri. Saka, mashandiro ayo ekudhonza mvura akanaka kwazvo uye anogona kushandiswa mumapurojekiti makuru.
