Netiweki yotulutsira madzi

一. Kapangidwe ka zinthu ndi mawonekedwe ake

1, ukonde wothira madzi:

Ukonde wothira madzi umapangidwa ndi pulasitiki yosagwira dzimbiri ndipo uli ndi mawonekedwe a maukonde amitundu itatu. Chifukwa chake, uli ndi mphamvu zabwino kwambiri zolowera madzi komanso kusefa. Pakati pa ukonde wothira madzi pali nthiti zokhuthala zoyimirira ndi nthiti yopingasa pamwamba ndi pansi, zomwe zimatha kupanga kapangidwe ka magawo atatu, komwe kumatha kutulutsa madzi apansi mwachangu kuchokera mumsewu ndikutseka madzi a capillary. Uli ndi geotextile yosaluka yobowoledwa ndi singano yolumikizidwa mbali zonse ziwiri kuti iwonjezere kusefa ndi kutulutsa madzi.

2, Geogrid:

Geogrid ndi chotchingira cha gridi cha magawo awiri kapena cha magawo atatu chopangidwa ndi ma polima okhala ndi ma molecular ambiri monga polypropylene ndi polyvinyl chloride kudzera mu thermoplastic kapena molding. Chingagawidwe m'magulu anayi: pulasitiki grille, chitsulo-pulasitiki grille, fiberglass grille ndi polyester warp-knitted polyester grille. Zipangizozi zimakonzedwa ndi njira zapadera ndipo zimakhala ndi mphamvu zambiri, kutalika kochepa komanso kukana dzimbiri. Ndi kapangidwe ka gridi, kotero imatha kutseka tinthu ta nthaka ndikukweza kukhazikika konse ndi mphamvu yonyamula katundu ya nthaka.

二. Ntchito ntchito

1, ukonde wothira madzi:

Ntchito yaikulu ya ukonde wothira madzi ndi kutulutsa madzi ndi kusefa. Umatha kutulutsa madzi omwe asonkhana pakati pa maziko ndi pansi, kutseka madzi a capillary, ndipo ukhoza kuphatikizidwa mu dongosolo la madzi othira madzi m'mphepete. Umathanso kuchita gawo lodzipatula komanso lolimbitsa maziko, kuletsa zinthu zazing'ono za subbase kuti zisalowe pansi, kuchepetsa kuyenda kwa mbali ya gawo loyambira, ndikuwonjezera mphamvu yothandizira maziko. M'nyengo yakumpoto, kuyika maukonde othira madzi kumatha kuchepetsa zotsatira za chisanu.

2, Geogrid:

Geogrid imatha kulimbitsa mphamvu ndi kukhazikika kwa nthaka. Imatha kupanga kapangidwe kolumikizana bwino ndi tinthu ta nthaka, ndikukweza umphumphu ndi mphamvu yonyamula nthaka. Ilinso ndi makhalidwe a kukana kusinthasintha kwamphamvu komanso kutalika pang'ono pakagwa kuphulika, ndipo imatha kusunga magwiridwe antchito okhazikika pansi pa katundu wa nthawi yayitali. Ikhozanso kukulitsa mphamvu yonyamula katundu ya chisakanizo cha phula ndikukweza magwiridwe antchito otumizira katundu pamsewu.

Chimodzi. Zochitika zogwiritsira ntchito

1, ukonde wothira madzi:

Maukonde otulutsira madzi angagwiritsidwe ntchito m'malo otayira zinyalala, m'malo otsetsereka, m'makoma amkati mwa ngalande ndi mapulojekiti ena omwe amafunikira kutulutsira madzi ndi kulimbitsa. Angathe kuthetsa mavuto a nthaka yosalimba komanso kutayira madzi kosakwanira, ndikukweza chitetezo ndi moyo wa ntchito ya pulojekitiyi.

2, Geogrid:

Geogrid ingagwiritsidwe ntchito m'madamu, kulimbitsa pansi pa nthaka, kuteteza malo otsetsereka, kulimbitsa makoma a ngalande ndi mapulojekiti ena. Ikhoza kupititsa patsogolo mphamvu ya nthaka yonyamula katundu komanso kukhazikika kwa nthaka, ndikuletsa kukokoloka kwa nthaka ndi kugwa kwa nthaka. Ingagwiritsidwenso ntchito pothandizira migodi ya malasha pansi pa nthaka, kuyika miyala ya nthaka ndi mapulojekiti ena.
