Geomembrane ya damu la m'madzi

Chithunzi Chojambulidwa cha Damu la Pool

Kufotokozera Kwachidule:

Ma geomembrane omwe amagwiritsidwa ntchito popangira madamu osungira madzi amapangidwa ndi zinthu zopangidwa ndi polima, makamaka polyethylene (PE), polyvinyl chloride (PVC), ndi zina zotero. Zinthuzi zimakhala ndi madzi ochepa kwambiri ndipo zimatha kuletsa madzi kulowa. Mwachitsanzo, polyethylene geomembrane imapangidwa kudzera mu polymerization reaction ya ethylene, ndipo kapangidwe kake ka molekyulu ndi kakang'ono kwambiri kotero kuti mamolekyu amadzi sangathe kudutsamo.

1.Makhalidwe Ogwira Ntchito

Kugwira Ntchito Koletsa Kutuluka kwa Madzi:
Iyi ndi ntchito yofunika kwambiri ya ma geomembranes pakugwiritsa ntchito madamu osungira madzi. Ma geomembranes abwino kwambiri amatha kukhala ndi mphamvu yolowera madzi yokwana 10⁻¹² - 10⁻¹³ cm/s, zomwe zimatseka madzi pang'ono. Poyerekeza ndi dongo lachikhalidwe loletsa madzi kutuluka, mphamvu yake yoletsa madzi kutuluka ndi yodabwitsa kwambiri. Mwachitsanzo, pansi pa kuthamanga komweko kwa mutu wa madzi, kuchuluka kwa madzi omwe amatuluka mu geomembrane ndi gawo laling'ono chabe la dongo loletsa madzi kutuluka.
Kugwira Ntchito Koletsa Kubowola:
Pakugwiritsa ntchito ma geomembranes pamadamu osungira madzi, amatha kubooledwa ndi zinthu zakuthwa monga miyala ndi nthambi mkati mwa thupi la damu. Ma geomembranes abwino amakhala ndi mphamvu yayikulu yoletsa kubooledwa. Mwachitsanzo, ma geomembranes ena okhala ndi ulusi wowonjezera mkati mwake amakhala ndi zigawo zolimbitsa ulusi zomwe zimatha kukana kubooledwa. Kawirikawiri, mphamvu yoletsa kubooledwa kwa ma geomembranes oyenerera imatha kufika 300 - 600N, kuonetsetsa kuti sadzawonongeka mosavuta m'malo ovuta a thupi la damu.
Kukana Ukalamba:
Popeza madamu osungira madzi amakhala ndi moyo wautali, ma geomembrane amafunika kukhala ndi mphamvu yolimbana ndi ukalamba. Zinthu zotsutsana ndi ukalamba zimawonjezedwa panthawi yopanga ma geomembrane, zomwe zimathandiza kuti azitha kugwira ntchito bwino kwa nthawi yayitali chifukwa cha zinthu zachilengedwe monga kuwala kwa ultraviolet ndi kusintha kwa kutentha. Mwachitsanzo, ma geomembrane okonzedwa ndi njira zapadera ndi njira zina amatha kukhala ndi moyo wautumiki wa zaka 30 - 50 panja.
Kusintha kwa Kusintha:
Damu lidzakumana ndi masinthidwe ena monga kukhazikika ndi kusuntha panthawi yosungira madzi. Ma geomembrane amatha kusintha masinthidwe otere popanda kusweka. Mwachitsanzo, amatha kutambasula ndi kupindika pang'ono pamodzi ndi kukhazikika kwa thupi la dam. Mphamvu yawo yokoka nthawi zambiri imatha kufika 10 - 30MPa, zomwe zimawathandiza kupirira kupsinjika komwe kumachitika chifukwa cha kusintha kwa thupi la dam.

Kulemera kwa geomembrane nthawi zambiri kumakhala pakati pa 0.3mm ndi 2.0mm.
- Kusalowa: Onetsetsani kuti geomembrane ili ndi kulowetsedwa bwino kuti madzi m'nthaka asalowe mu polojekitiyi.

2. Mfundo Zofunika Zokhudza Kapangidwe ka Nyumba

Chithandizo Chachikulu:
Musanayike ma geomembrane, maziko a damu ayenera kukhala athyathyathya komanso olimba. Zinthu zakuthwa, udzu, dothi lotayirira ndi miyala pamwamba pa maziko ziyenera kuchotsedwa. Mwachitsanzo, cholakwika cha kuthyathyathya kwa maziko nthawi zambiri chimayenera kulamulidwa mkati mwa ±2cm. Izi zitha kuletsa geomembrane kuti isakandane ndikuwonetsetsa kuti geomembrane ndi maziko ake zikugwirizana bwino kuti zisamatuluke madzi.
Njira Yoyikira:
Ma geomembrane nthawi zambiri amalumikizidwa pogwiritsa ntchito welding kapena bonding. Powelda, ndikofunikira kuonetsetsa kuti kutentha kwa welding, liwiro ndi kupanikizika ndizoyenera. Mwachitsanzo, pa ma geomembrane ovekedwa ndi kutentha, kutentha kwa welding nthawi zambiri kumakhala pakati pa 200 - 300 °C, liwiro la welding ndi pafupifupi 0.2 - 0.5m/min, ndipo kuthamanga kwa welding ndi pakati pa 0.1 - 0.3MPa kuti zitsimikizire kuti welding ndi yabwino komanso kupewa mavuto otuluka chifukwa cha welding yoipa.
Kulumikizana kwa Peripheral:
Kulumikizana kwa ma geomembrane ndi maziko a damu, mapiri mbali zonse ziwiri za damu, ndi zina zotero m'mphepete mwa damu ndikofunikira kwambiri. Kawirikawiri, mipanda yomangira, zipilala za konkire, ndi zina zotero zidzagwiritsidwa ntchito. Mwachitsanzo, ngalande yomangira yokhala ndi kuya kwa 30 - 50cm imayikidwa pa maziko a damu. Mphepete mwa geomembrane imayikidwa mu ngalande yomangira ndikukhazikika ndi zinthu zomangira nthaka kapena konkire kuti zitsimikizire kuti geomembrane ilumikizidwa bwino ndi zomangamanga zozungulira ndikuletsa kutuluka kwa madzi m'mbali mwake.

3. Kukonza ndi Kuyang'anira

Kusamalira Nthawi Zonse:
Ndikofunikira kuyang'ana nthawi zonse ngati pali kuwonongeka, kung'ambika, kubowoka, ndi zina zotero pamwamba pa geomembrane. Mwachitsanzo, panthawi yogwira ntchito ya damu, ogwira ntchito yokonza amatha kuchita kafukufuku kamodzi pamwezi, kuyang'ana kwambiri pakuwunika geomembrane m'malo omwe madzi amasintha pafupipafupi komanso madera omwe ali ndi mawonekedwe akuluakulu a thupi la damu.
Njira Zowunikira:
Njira zoyesera zosawononga zitha kugwiritsidwa ntchito, monga njira yoyesera spark. Mu njira iyi, magetsi enaake amagwiritsidwa ntchito pamwamba pa geomembrane. Pakawonongeka geomembrane, sparks zidzapangidwa, kuti mfundo zowonongeka zipezeke mwachangu. Kuphatikiza apo, palinso njira yoyesera vacuum. Malo otsekedwa amapangidwa pakati pa geomembrane ndi chipangizo choyesera, ndipo kukhalapo kwa kutuluka kwa spark mu geomembrane kumaweruzidwa powona kusintha kwa vacuum degree.
