Ntchito ya mphasa yotulutsira madzi ya mafunde ophatikizika

Kapangidwe ndi makhalidwe a mphasa yotulutsa madzi ya mafunde yophatikizika

Mpando wothira madzi wopangidwa ndi corrugated drainage umapangidwa ndi ulusi wa polima (monga polypropylene, ndi zina zotero) womwe umalukidwa ndi kusungunuka ndi kuyala, kupanga kapangidwe kake ndi njira zokhazikika zothira madzi. Chifukwa chake, mpando wothira madzi uli ndi mphamvu yabwino kwambiri yolimbana ndi kupanikizika, kutseguka kwakukulu, kusonkhanitsa madzi mbali zambiri komanso ntchito zothira madzi mopingasa. Mpando wina wothira madzi wopangidwa ndi corrugated drainage umaphatikizanso ma mesh a polypropylene okhala ndi mbali zitatu ndi ma geotextiles osalukidwa, omwe amatha kupanga kapangidwe ka drainage ka magawo atatu kotsutsana ndi kusefa, kutulutsa madzi ndi kuteteza kudzera mu mgwirizano wa kutentha. Kapangidwe kameneka ka corrugated sikungowonjezera mphamvu ndi kulimba kwa mpando wothira madzi, komanso kumawonjezera magwiridwe antchito ake othira madzi komanso kuchuluka kwa momwe amagwiritsidwira ntchito.

二. Ntchito yaikulu ya mphasa yotulutsa madzi ya composite wave

1, Kutulutsa madzi bwino

Kapangidwe ka mafunde a mphasa yolumikizira mafunde ingawonjezere kugwedezeka kwa njira yoyendera madzi, kuchepetsa liwiro la kuyenda kwa madzi ndikuwonjezera magwiridwe antchito a njira yoyendetsera madzi. Kapangidwe ka njira yoyendetsera madzi mkati mwake kamatha kusonkhanitsa ndikutulutsa madzi apansi panthaka kapena amvula mwachangu, kuchepetsa chinyezi m'nthaka ndikuletsa kusefukira kwa madzi. Chifukwa chake, ingagwiritsidwe ntchito pa ntchito zosamalira madzi, kumanga misewu, kuletsa madzi kulowa pansi panthaka ndi minda ina.

2, Kulimbitsa bata la kapangidwe

Kapangidwe kake kakhoza kuwonjezera malo olumikizirana pakati pa mphasa yotulutsira madzi ndi nthaka yozungulira, kukweza mphamvu yokangana ndikuwonjezera kukhazikika kwa nyumbayo. Kudzera mu ngalande, kuchuluka kwa madzi m'nthaka kumatha kuchepetsedwa, ndipo kukhazikika kwa maziko ndi malo otsetsereka kumatha kulumikizidwa. Poteteza misewu ikuluikulu, njanji ndi mizere ina ya magalimoto, kugwiritsa ntchito mphasa yotulutsira madzi ya mafunde ophatikizika kumatha kuletsa kugwa kwa malo otsetsereka ndi kukokoloka kwa nthaka, ndikuwonetsetsa kuti kuyendetsa bwino.

3. Kudzipatula ndi chitetezo

Mpando wothira madzi wa mafunde ophatikizika ungagwiritsidwe ntchito ngati gawo lolekanitsa pakati pa zipangizo zosiyanasiyana kuti upewe kusakanikirana ndi kuipitsidwa pakati pa zinthu zosiyanasiyana. Mu uinjiniya wa pansi pa nthaka, umagwira ntchito ngati gawo losalowa madzi kuti uteteze nyumba za pansi pa nthaka ku chinyezi. Mpando wothira madzi ukhozanso kufalikira ndikuchepetsa kupanikizika kwa katundu wapamwamba pa maziko, ndikukweza mphamvu yonyamula madzi ya maziko.

4. Kuteteza chilengedwe ndi kubwezeretsa chilengedwe

Mu mapulojekiti oteteza chilengedwe monga kubwezeretsa zachilengedwe ndi malo otayira zinyalala, mphasa yothira madzi ya mafunde ophatikizika ingagwiritsidwe ntchito kupatula zinthu zodetsa ndikulimbikitsa kubwezeretsa zachilengedwe. Mphamvu zake zotsutsana ndi asidi ndi alkali komanso zotsutsana ndi dzimbiri zimathandiza mphasa yothira madzi kukhalabe ndi ntchito yokhazikika m'malo ovuta, zomwe zimapereka chithandizo cha nthawi yayitali komanso chodalirika cha madzi othira madzi pa ntchito zobwezeretsa zachilengedwe.

三. Kugwiritsa ntchito

1. Mu mapulojekiti osamalira madzi monga malo osungiramo madzi, makoma osungira madzi ndi malamulo a mitsinje, kugwiritsa ntchito mphasa zotulutsira madzi kungalepheretse kusefukira kwa madzi, kuteteza makoma osungira madzi ndi kukhazikika m'mitsinje.

2, Pomanga zomangamanga zoyendera monga msewu waukulu ndi sitima, mphasa yotulutsira madzi ingathandize 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, mati otulutsira madzi a m'nyanja angagwiritsidwenso ntchito.
