Chifukwa chakuchita bwino kwambiri kwa anti-seepage komanso mphamvu zamakina apamwamba kwambiri, polyethylene (PE) imagwiritsidwa ntchito kwambiri m'magawo ambiri. Pazinthu zomangira, polyethylene yapamwamba kwambiri (HDPE) geomembrane, monga mtundu watsopano wa zinthu za geotechnical, imagwiritsidwa ntchito kwambiri mu uinjiniya monga kusungirako madzi, kuteteza chilengedwe, ndi malo otayirapo. Nkhaniyi ipereka chidziwitso chatsatanetsatane, kugwiritsa ntchito, komanso ubwino wa polyethylene geomembrane wochuluka kwambiri.

1, Chiyambi cha polyethylene geomembrane wochuluka kwambiri

High kachulukidwe polyethylene geomembrane ndi mtundu wa zinthu geosynthetic opangidwa makamaka mkulu-kachulukidwe polyethylene (HDPE), amene ali mkulu mawotchi mphamvu ndi kukana dzimbiri. Poyerekeza ndi zida zachikhalidwe zosalowa madzi, polyethylene geomembrane yolimba kwambiri imakhala ndi magwiridwe antchito abwino kwambiri otsutsana ndi seepage komanso moyo wautali wautumiki. Mafotokozedwe ake nthawi zambiri amakhala 6 mita m'lifupi ndi 0.2 mpaka 2.0 mamilimita mu makulidwe. Malinga ndi malo osiyanasiyana ogwiritsira ntchito, mtundu wa polyethylene geotextile wochuluka kwambiri ukhoza kugawidwa kukhala wakuda ndi woyera.

2. Kugwiritsa ntchito kwambiri kachulukidwe polyethylenegeombrane

1. Madzi osungira madzi: High kachulukidwe polyethylene geomembrane imagwiritsidwa ntchito kwambiri muumisiri wosungira madzi, monga malo osungiramo madzi, mizati, kasamalidwe ka mtsinje, ndi zina zotero. kuteteza bwino kulowa m'madzi ndi kukokoloka, ndikuwongolera chitetezo ndi kukhazikika kwaukadaulo wama hydraulic.

2. Zomangamanga za chilengedwe: Mu zomangamanga zachilengedwe, polyethylene geomembrane ya polyethylene yamtengo wapatali imagwiritsidwa ntchito makamaka potsutsa-seepage ndi kudzipatula m'malo monga malo otayira ndi zimbudzi. Chifukwa cha anti-seepage ndi kukana kwa dzimbiri, polyethylene geomembrane ya polyethylene yapamwamba imatha kuteteza bwino kutayikira kwa zinyalala ndi zinyalala, kuteteza madzi apansi ndi nthaka.

3. Umisiri wa zomangamanga: Pa zomangamanga, polyethylene geomembrane yolimba kwambiri imagwiritsidwa ntchito makamaka poletsa madzi komanso kudzipatula m'zipinda zapansi, tunnel, subways, ndi malo ena. Poyerekeza ndi zida zachikale zopanda madzi, polyethylene geomembrane yokhala ndi kachulukidwe yapamwamba imakhala ndi magwiridwe antchito abwino kwambiri otsutsana ndi seepage komanso moyo wautali wautumiki, womwe ungapangitse chitetezo ndi bata la nyumba.

3. Ubwino wa polyethylene geomembrane yapamwamba kwambiri

1. Kuchita bwino kwa anti-seepage: High density polyethylene geomembrane ili ndi ntchito yabwino kwambiri yotsutsa-seepage, yomwe ingalepheretse bwino kulowetsa madzi ndi kukokoloka kwa madzi, komanso kupititsa patsogolo chitetezo ndi kukhazikika kwa ntchito zosungira madzi.

2. Kukana kwamphamvu kwa dzimbiri: High kachulukidwe polyethylene geomembrane ali ndi mphamvu dzimbiri kukana ndipo akhoza kukana kukokoloka kwa mankhwala osiyanasiyana, mogwira kuteteza zimbudzi ndi zinyalala kutayikira.

3. Moyo wautali wautumiki: Moyo wautumiki wa polyethylene geomembrane wochuluka kwambiri nthawi zambiri ndi zaka 20, zomwe zingathe kuchepetsa bwino ndalama zokonza uinjiniya.

4. Kumanga kosavuta: Kumanga kwa polyethylene yapamwamba kwambirigeombranendi yosavuta, ndipo imatha kulumikizidwa ndi kuwotcherera kapena kulumikiza. Kuthamanga kwa zomangamanga kumathamanga, komwe kungathe kuchepetsa nthawi ya polojekitiyo.

5. Chitetezo cha chilengedwe: Kuchuluka kwa polyethylene geomembrane ya polyethylene geomembrane ndi yopanda poizoni komanso yopanda fungo, sikutulutsa zinthu zovulaza, sikuvulaza chilengedwe, ndipo kumakwaniritsa zofunikira za chilengedwe. Pakadali pano, chifukwa chakuchita bwino kwa anti-seepage, imatha kuletsa kutulutsa kwazinthu zovulaza ndikuwonetsetsa chitetezo cha miyoyo ya anthu ndi katundu.
4, Mapeto
Mwachidule, polyethylene geomembrane yapamwamba kwambiri, monga mtundu watsopano wa zinthu za geotechnical, ili ndi ubwino monga ntchito yabwino yotsutsa-seepage, kukana dzimbiri, moyo wautali wautumiki, zomangamanga zosavuta, kuteteza chilengedwe ndi chitetezo. Choncho, amagwiritsidwa ntchito kwambiri m'madera monga kusungirako madzi, kuteteza chilengedwe, ndi zomangamanga. Ndi chitukuko chosalekeza cha teknoloji, ntchito ndi kugwiritsa ntchito kwa polyethylene geomembrane ya polyethylene geomembrane idzakulitsidwa ndi kukonzedwa bwino, ndikupereka ntchito zabwino zopangira anthu ndi moyo.
