Geomembrane imagwiritsidwa ntchito makamaka pa ntchito zochotsa zinyalala zomwe sizingatuluke madzi, komanso zochotsa madzi amvula ndi zimbudzi.

Geomembrane, nembanemba yopangidwa ndi zinthu za polima, imagwiritsidwa ntchito m'magawo ambiri, makamaka ntchito zochotsera zinyalala zomwe sizingalowe m'madzi komanso zochotsa madzi amvula ndi zimbudzi, chifukwa cha kuletsa madzi kulowa m'madzi, kuletsa kutuluka kwa madzi, kuchotsa fungo loipa, kusonkhanitsa biogas, kukana dzimbiri komanso makhalidwe oletsa kukalamba.

一. Makhalidwe oyambira a geomembrane

Geomembrane ndi chinthu chotchinga chosalowa madzi chomwe chimachokera ku polima ya molekyulu yambiri, polyethylene yotsika kwambiri (LDPE) Geomembrane, polyethylene yotsika kwambiri (HDPE) Geomembrane ndi chinthu cha filimu chomwe chili ndi mphamvu zambiri, kukana dzimbiri kwambiri, kukana kukalamba kwambiri komanso magwiridwe antchito abwino oletsa kutayikira. Ubwino waukulu wa geomembrane uli mu magwiridwe ake abwino kwambiri oletsa kutayikira, omwe amatha kuletsa kulowa kwa madzi ndikuteteza madzi apansi panthaka ndi nthaka ku kuipitsidwa. Njira yomanga geomembrane ndi yosavuta komanso yosavuta kugwiritsa ntchito, zomwe zingafupikitse nthawi yomanga ndikuwonjezera magwiridwe antchito omanga. Imagwiritsidwa ntchito makamaka pochotsa zinyalala, malo osungiramo zinthu zakale, njira zoletsa kutayikira kwa madzi, madamu oletsa kutayikira kwa madzi ndi uinjiniya wa subway, ndi zina zotero.

Kugwiritsa ntchito geomembrane poletsa kutaya zinyalala

Mu mapulojekiti oteteza chilengedwe monga malo otayira zinyalala, ma geomembrane, monga zigawo zosalowa madzi, amachita gawo lofunika kwambiri. Chifukwa cha kufulumira kwa kukula kwa mizinda, kutaya zinyalala kwakhala gawo lofunika kwambiri pa kayendetsedwe ka mizinda. Njira zachikhalidwe zotayira zinyalala nthawi zambiri zimakhala ndi chiopsezo cha kutuluka kwa madzi m'madzi ndi nthaka, ndipo kugwiritsa ntchito ma geomembrane kumathetsa vutoli bwino.

1. Pewani kuipitsidwa ndi madzi otayidwa: Mwa kuyika ma geomembrane pansi ndi mozungulira malo otayidwa zinyalala, chotchinga cholimba choletsa madzi otayidwa zinyalala chimapangidwa, chomwe chimaletsa madzi otayidwa zinyalala kuti asalowe m'madzi apansi panthaka ndi m'nthaka ndikuteteza chitetezo cha chilengedwe chozungulira.
2. Kukonza kukhazikika kwa malo otayira zinyalala: Geomembrane sikuti imangokhala ndi ntchito yoletsa kutuluka kwa zinyalala, komanso imathandizira kukhazikika kwa malo otayira zinyalala ndikuletsa zoopsa zomwe zingachitike monga kukhazikika kwa maziko ndi kugwa kwa nthaka chifukwa cha kuchulukana kwa madzi otayira zinyalala.
3. Kuchepetsa ndalama zokonzera: Kugwiritsa ntchito ma geomembrane kumachepetsa kufunika kokonza madzi otayidwa ndi madzi ndipo kumachepetsa ndalama zokonzera zina pamene kukulitsa nthawi yogwiritsira ntchito malo otayira zinyalala.

Gawo lofunika la geomembrane m'mapulojekiti osinthira madzi amvula ndi zimbudzi

Kusamutsa madzi amvula ndi zimbudzi ndi njira yofunika kwambiri yomangira njira zotulutsira madzi m'mizinda, cholinga chake ndi kusonkhanitsa, kunyamula ndi kukonza madzi amvula ndi zimbudzi padera kuti apititse patsogolo kugwiritsa ntchito bwino madzi ndi malo abwino okhala ndi madzi. Geomembrane imagwiranso ntchito yofunika kwambiri pa ntchitoyi.

1. Kupeza kulekanitsa bwino madzi amvula ndi zimbudzi: Mwa kuyika ma geomembranes m'zigawo zofunika monga kuwongolera matanki, gawo lodzipatula pakati pa madzi amvula ndi zimbudzi limapangidwa kuti zitsimikizire kuti madzi amvula salowa m'zimbudzi ndikuchepetsa kuchuluka kwa ntchito zotsukira zimbudzi ndi ndalama zogwirira ntchito.
2. Kukweza ubwino wa madzi: Kugwira ntchito kwa geomembrane kosatulutsa madzi kumateteza bwino zinthu zoopsa zomwe zili m'zimbudzi kuti zisafalikire ku malo ozungulira, komanso kumateteza chitetezo cha madzi pamwamba ndi pansi pa nthaka.
3. Kukhazikika kwa dongosolo: Makhalidwe amphamvu kwambiri a geomembranes amawathandiza kupirira zovuta zachilengedwe ndi kusintha kwa nyengo, kuonetsetsa kuti madzi amvula ndi zimbudzi zikukhazikika komanso kudalirika.

Zochitika zamtsogolo pa chitukuko

Ndi kukulitsa chidziwitso cha chilengedwe komanso kupita patsogolo kwa ukadaulo, kugwiritsa ntchito ma geomembranes m'malo otayira zinyalala omwe salola madzi kulowa m'madzi komanso mapulojekiti ochotsa madzi amvula ndi zinyalala kudzakhala kwakukulu komanso kozama. M'tsogolomu, konzani kugwiritsa ntchito ma geomembranes m'magawo ambiri, monga ulimi wothirira, kubwezeretsa zachilengedwe, ndi zina zotero, kuti mulimbikitse chitukuko chake pamsika waukulu.

Mwachidule, ma geomembranes amagwira ntchito yofunika kwambiri m'mapulojekiti ochotsa zinyalala m'malo otayira zinyalala komanso ochotsa madzi amvula ndi zinyalala chifukwa cha ubwino wawo wapadera. Ndi kupita patsogolo kwa ukadaulo komanso kufalikira kwa ntchito, ma geomembranes adzachita gawo lofunika kwambiri pakuteteza chilengedwe mtsogolo ndikuthandizira kumanga malo obiriwira komanso okhazikika m'mizinda.
