Kodi netiweki yotulutsira madzi ya magawo atatu ingalepheretse matope kulowa?

Ukonde wothira madzi wopangidwa ndi mbali zitatu ndi chinthu chomwe chimagwiritsidwa ntchito kwambiri pa ntchito zazikulu. Ndiye, kodi ungaletse matope kulowa?

I. Kapangidwe ka zinthu ndi njira yoletsa matope

Ukonde wothira madzi wa magawo atatu umapangidwa ndi ukonde wapulasitiki wa magawo atatu wokhala ndi geotextile yolumikizira mbali ziwiri, kotero kuti ntchito yake yothira madzi ndi yabwino kwambiri. Pakati pake ndi pakati pa geonet wa magawo atatu, womwe uli ndi nthiti yolimba yoyima ndi nthiti yopendekera pamwamba ndi pansi kuti apange njira yothira madzi yogwira ntchito bwino. Nthiti zolumikizidwa bwino sizimangowonjezera kukhazikika kwa kapangidwe kake, komanso zimalepheretsa geotextile kuti isalowe mu njira yothira madzi, ndikusunga ntchito yabwino yothira madzi ngakhale ikanyamula katundu wambiri.

Chifukwa chake, imatha kutulutsa madzi mwachangu panthawi yotulutsa madzi, komanso ingagwiritse ntchito mphamvu yoletsa kusefa ya geotextile kuti isalowe mu ngalande yotulutsira madzi, zomwe zingalepheretse kuti matope asalowe. Ukonde wotulutsira madzi wokhala ndi magawo atatu ulinso ndi kukana dzimbiri komanso kukana asidi ndi alkali, kotero nthawi yake yogwira ntchito ndi yayitali.

II. Zitsanzo za mfundo zogwirira ntchito ndi momwe zimagwiritsidwira ntchito

Mu ntchito yeniyeni, ukonde wothira madzi wa magawo atatu ukhoza kuthetsa mavuto a madzi otuluka m'misewu, m'mabwalo amisewu, m'matanthwe ndi mapulojekiti ena kudzera mu njira yake yapadera yothira madzi. Mwachitsanzo, m'mapulojekiti amisewu, kuuyika pansi pa msewu kumatha kutulutsa chinyezi mwachangu m'mapangidwe a msewu ndikuletsa chinyezi kulowa m'mabwalo amisewu, zomwe zimapangitsa kuti bedi lamisewu lifewe kapena kuwonongeka. Mphamvu yake yoletsa kusefa imathanso kuletsa tinthu ta dothi la m'mabwalo amisewu kulowa m'mabwalo amisewu ndikusunga njira yothira madzi kuti isatsekedwe.

Mu malo otayira zinyalala, sizingangokhala ngati malo otayira zinyalala pansi pa nthaka kuti zitulutse madzi apansi panthaka mwachangu m'malo otayira zinyalala, komanso ngati malo osonkhanitsira zinyalala ndi zinyalala kuti zisonkhanitse ndi kutulutsa zinyalala zomwe zimapangidwa panthawi yotayira zinyalala. Munjira imeneyi, kugwiritsa ntchito kwake kophatikizana ndi ma geotextiles osalukidwa kungathandize kuti zisamatseke, kuonetsetsa kuti zinyalala zimatulutsa bwino, komanso kupewa kuipitsa chilengedwe komwe kumachitika chifukwa cha kutsekeka.

Monga momwe taonera pamwambapa, ukonde wothira madzi wopangidwa ndi mbali zitatu umathandiza kupewa kutsekeka kwa madzi. Sikuti umangothetsa mavuto a madzi otuluka m'misewu, m'mabwalo amisewu, m'matanthwe a ngalande ndi mapulojekiti ena okha, komanso umagwira ntchito yofunika kwambiri m'malo apadera monga malo otayira zinyalala.
