Dimple ngalande bolodi akhoza mwamsanga ndi mogwira katundu madzi a mvula, kuchepetsa kapena kuthetsa malo amodzi madzi kuthamanga kwa madzi wosanjikiza wosanjikiza, mwa mfundo imeneyi yogwira madzi conduction angakwaniritse zotsatira yogwira madzi.
Kuchita kwamadzi: Polyethylene (HDPE) dimple drainage board material palokha ndi yabwino kwambiri yopanda madzi.Gulu lopanda madzi ndi ngalande limakhala chinthu chabwino chothandizira madzi potengera njira yolumikizira yodalirika.

1. Zomangamanga: zobiriwira pamwamba pa garaja, dimba la padenga, bwalo la mpira, gofu, polojekiti yam'mphepete mwa nyanja.
2. Mainjiniya a Municipal: misewu, njira yapansi panthaka, ngalande, malo otayirapo.
3. Zomangamanga: kumtunda kapena pansi kwa maziko a nyumba, khoma lapansi, kusefera zogona ndi kutsekereza kutentha.
4. Kukonza magalimoto: msewu waukulu, chipinda chapansi pa njanji, damu ndi malo otsetsereka.
1. Tsukani zinyalala ndi kuyika simenti pamalo oyikapo, kuti pasapezeke kugundana koonekeratu pamalopo, ndi 2-5 ‰ otsetsereka pamafunika padenga la garaja ndi dimba la denga.
2. Ikhoza kutulutsa madzi otengedwa kuchokera ku ngalande kupita kumtsinje wapafupi kapena ngalande yapafupi ya mzinda.
3 chapansi pansi odana seepage madzi, mu maziko pamwamba pa pansi, ndiye kuti, pamaso kuchita pansi kuchita wosanjikiza wa dimple ngalande bolodi, ndi dimples kukhudza maziko, kusiya dzenje akhungu, kuti madzi apansi asabwere, seepage. mwachibadwa kudzera mu danga la dimple ngalande bolodi mu ozungulira dzenje akhungu, ndiye kudzera mu dzenje akhungu kulowa sump.
4. Madzi oletsa kutuluka m'chipinda chapansi mkati mwa khoma lamkati, bolodi la dimple litha kuyikidwa pakhoma lalikulu la nyumbayo, ndipo ma dimples amayang'ana khoma lalikulu.The dimpled ngalande bolodi amatetezedwa ndi wosanjikiza wa khoma limodzi kapena wosanjikiza zitsulo waya mauna simenti, kotero kuti danga seepage bolodi kunja kwa khoma umayenda molunjika mu dzenje akhungu ndi mwachindunji amatsogolera ku sump.
5. Mukamayala matabwa pamalo aliwonse, muyenera kuyang'anitsitsa: musalole nthaka, simenti, mchenga wachikasu ndi zinyalala zina kulowa kutsogolo kwa ngalande kuti malo a ngalande azikhala bwino.
6. Pamene dimple drainage board iikidwa, njira zodzitetezera ziyenera kuchitidwa momwe zingathere, ndipo kubwezera kumbuyo kuyenera kuchitika mwamsanga pamene bolodi la drainage likuyikidwa pamtunda kapena mu garaja yakunja, kuti muteteze kumtunda. mphepo yowomba mopanda dongosolo la ngalandezi ndi kusokoneza kuyala bwino.Pansi ndi mkati khoma madzi posachedwapa kuchita ntchito yabwino yoteteza wosanjikiza, kuteteza ngalande bolodi kuonongeka ndi anthu kapena zinthu.
7. Nthaka yobwerera kumbuyo ndi dothi lowoneka bwino, ndipo ndi bwino kufalitsa mchenga wachikasu wa 3-5 masentimita pa geotextile, yomwe imathandizira kusefa kwamadzi kwa geotextile;Ngati backfill ndi mtundu wa dothi lopatsa thanzi kapena dothi lopepuka, palibe chifukwa choyika mchenga wachikasu, nthakayo imakhala yotayirira komanso yosavuta kusefa madzi.
8. Bolodi la ngalande likayalidwa, limatha kupindika ndi mbali yakumanja ya ngalandeyo pamagawo 1-2 a fulcrum otsatirawa.Itha kukutidwanso ndi mbale ziwiri zapansi pamodzi ndi geotextile.
