Mati otulutsa madzi opangidwa ndi mafunde opangidwa ndi ma composite ndi zinthu zomwe zimagwiritsidwa ntchito kwambiri mu uinjiniya. Ndiye ntchito zawo ndi ziti?
1. Kapangidwe ndi makhalidwe a mphasa yothira madzi ya mafunde ophatikizika
Pedi yolumikizira madzi ya mafunde ophatikizika ndi kapangidwe kake kamene kali ndi njira yokhazikika yolumikizidwa ndi njira yosungunula. Chifukwa chake, pedi yolumikizira madzi imakhala ndi kukana kwabwino kwambiri kwa kupanikizika, kutseguka kwakukulu, komanso ntchito zosonkhanitsa madzi m'njira zambiri komanso zopingasa. Mapedi ena olumikizira madzi a mafunde ophatikizika amaphatikizanso mapedi a polypropylene mesh okhala ndi magawo atatu ndi ma geotextiles osalukidwa. Kudzera mu mgwirizano wa kutentha, imatha kupanga kapangidwe ka madzi amitundu itatu komwe kamasefa mozungulira, kutulutsa madzi ndi kuteteza. Kapangidwe kameneka sikuti kamangowonjezera mphamvu ndi kulimba kwa pedi yolumikizira madzi, komanso kumawonjezera magwiridwe antchito ake otulutsa madzi komanso momwe amagwiritsidwira ntchito.
2. Ntchito yaikulu ya composite wave drainage pad
1. Kutulutsa madzi bwino
Kapangidwe ka mafunde a composite wave drainage pad kangathe kuwonjezera kugwedezeka kwa njira yoyendera madzi, kuchepetsa liwiro la madzi, ndikuwonjezera magwiridwe antchito a madzi. Njira yoyendetsera madzi mkati mwake idapangidwa kuti itenge ndikutulutsa madzi apansi panthaka kapena amvula mwachangu, kuchepetsa chinyezi m'nthaka ndikuletsa kusefukira kwa madzi. Chifukwa chake, ingagwiritsidwe ntchito pamapulojekiti osamalira madzi, kumanga misewu, kuletsa madzi kulowa pansi panthaka ndi minda ina.
2. Limbikitsani kukhazikika kwa kapangidwe kake
Kapangidwe kake kakhoza kuwonjezera malo olumikizirana pakati pa payipi yotulutsira madzi ndi nthaka yozungulira, kuwonjezera kukangana, ndikuwonjezera kukhazikika kwa kapangidwe kake konse. Kudzera mu ngalande, chinyezi cha nthaka chikhoza kuchepetsedwa, ndipo kukhazikika kwa maziko ndi malo otsetsereka kumatha kulumikizidwa. Poteteza malo otsetsereka a misewu yayikulu ndi njanji ndi mizere ina ya magalimoto, kugwiritsa ntchito matiresi otulutsira madzi a mafunde ophatikizika kungalepheretse kugwa kwa malo otsetsereka ndi kukokoloka kwa nthaka ndikuwonetsetsa kuti kuyendetsa bwino.
3. Kudzipatula ndi kuteteza
Chopopera madzi cha mafunde chophatikizika chingathe kugwira ntchito ngati chopatulira pakati pa zinthu zosiyanasiyana kuti chipewe kusakanikirana ndi kuipitsidwa pakati pa zinthu zosiyanasiyana. Mu uinjiniya wapansi panthaka, chingathe kugwira ntchito ngati chopopera madzi kuti chiteteze kapangidwe ka pansi panthaka kuti kasawonongeke ndi chinyezi. Chopopera madzi chingathenso kufalikira ndikuchepetsa kupanikizika pa maziko ndi katundu wapamwamba ndikukweza mphamvu ya maziko.
4. Kuteteza chilengedwe ndi kubwezeretsa chilengedwe
Mu mapulojekiti oteteza chilengedwe monga kubwezeretsa zachilengedwe ndi malo otayira zinyalala, mapeti ophatikizana amadzi otulutsa madzi angagwiritsidwe ntchito kupatula zinthu zodetsa ndikulimbikitsa kubwezeretsa zachilengedwe. Kukana kwake asidi ndi alkali komanso kukana dzimbiri kumatha kusunga magwiridwe antchito okhazikika a mapeti otulutsa madzi m'malo ovuta, kupereka chithandizo cha madzi otulutsa madzi kwa nthawi yayitali komanso chodalirika pa ntchito zobwezeretsa zachilengedwe.
III. Kugwiritsa Ntchito
1. Mu mapulojekiti osamalira madzi monga malo osungira madzi, makoma a mitsinje, ndi kasamalidwe ka mitsinje, kugwiritsa ntchito mphasa zotulutsira madzi kungalepheretse kusefukira kwa madzi, kuteteza makoma a mitsinje, komanso kulimbitsa madera a mitsinje.
2. Pomanga misewu ikuluikulu, njanji ndi zomangamanga zina zoyendera, mphasa zotulutsira madzi zimatha kupititsa patsogolo kukhazikika ndi chitetezo cha malo otsetsereka.
3. Mu ntchito zoteteza madzi ndi zotulutsira madzi m'nyumba zapansi panthaka monga zipinda zapansi panthaka ndi magaraji apansi panthaka, mapeti otulutsira madzi a mafunde amitundu yosiyanasiyana angagwiritsidwenso ntchito.
