Chivundikiro cha Manhole Chosapanga Chitsulo Chosapanga Chitsulo
Mbali Za Chivundikiro cha Manhole Chosapanga Chitsulo Chosapanga Chitsulo
Chivundikiro cha chimbudzi chosaoneka chachitsulo chosapanga dzimbiri chimapangidwa ndi mbale yachitsulo chosapanga dzimbiri yamphamvu kwambiri ngati maziko, ndipo chitsulo cha ngodya ya pansi chimalimbikitsidwa, kudulidwa, ndi kupindika, komanso ukadaulo wonse wa argon-fluorine welding welding. Ili ndi ubwino wokhala ndi mawonekedwe okongola komanso okongola, mphamvu yonyamulira katundu, moyo wautali, kapangidwe kake kamphamvu komanso magwiridwe antchito okhazikika.

Chivundikiro cha dzenje la madzi
1. Zophimba za maenje zimagwiritsidwa ntchito kuphimba zitsime zakuya m'misewu kapena m'nyumba kuti anthu kapena zinthu zisagwe. Kawirikawiri zimakhala zozungulira. Zingagwiritsidwe ntchito m'mabande obiriwira, m'misewu yoyenda anthu, m'misewu yamagalimoto, m'madoko, m'misewu ing'onoing'ono, ndi zina zotero.
2. Kugawa chivundikiro cha dzenje la m'chimbudzi
① Yagawidwa m'magulu malinga ndi zinthu
1) Zophimba zachitsulo: chitsulo chosungunuka, chitsulo chosungunuka, zophimba za mkuwa, ndi zina zotero.
2) Zophimba za simenti ya simenti yachitsulo champhamvu kwambiri (zipangizo zopangidwa ndi simenti).
3) Zophimba maenje a utomoni wobwezerezedwanso (zipangizo zophatikizika zopangidwa ndi utomoni wobwezerezedwanso).
4) Zophimba maenje okhala ndi zinthu zopangidwa ndi polima, ndi zina zotero.
② Yogawidwa m'magulu malinga ndi mawonekedwe
1) Zophimba zozungulira za dzenje lolowera madzi
2) Zophimba za chimbudzi chapakati
Ponena za kayendetsedwe ka misewu ya m'mizinda, zophimba maenje ozungulira nthawi zambiri zimagwiritsidwa ntchito chifukwa sizingapendekeke kwambiri ndipo zimatha kuteteza bwino chitetezo cha oyenda pansi ndi magalimoto.
M'madera akumidzi ndi m'zitsime za cable, nthawi zambiri zimagwiritsidwa ntchito za sikweya, zomwe zingalepheretse bwino kulowa kwa madzi amvula ndi zakumwa zina.
3. Kugawa magulu a chivundikiro cha dzenje
Malinga ndi Gawo 4 la GB/T23858-2009 "Ma Manhole Covers", ma Manhole covers amagawidwa m'magulu asanu ndi limodzi kutengera mphamvu yawo yonyamula katundu:
Gulu Loyamba: (Mtundu wocheperako wa giredi A15 uyenera kusankhidwa): Malamba obiriwira, misewu yoyenda pansi ndi madera ena komwe magalimoto saloledwa kulowa.
Gulu Lachiwiri: (Kusankha kochepa kwa mtundu wa B125): Malo oyenda pansi, njira zamagalimoto osagwiritsa ntchito injini, malo oimika magalimoto ang'onoang'ono ndi malo oimika magalimoto pansi pa nthaka.
Gulu Lachitatu: (Osachepera mtundu wa C250 wasankhidwa): Midzi yokhalamo, misewu yakumbuyo ndi zigwa, malo omwe magalimoto opepuka kapena magalimoto ang'onoang'ono okha ndi omwe amayenda, mkati mwa mamita 0.5 kuchokera ku miyala yopingasa mbali zonse ziwiri za msewu.
Gulu Lachinayi: (Kusankha kochepa kwa mtundu wa D400): Misewu ya m'mizinda, misewu ikuluikulu, misewu yapamwamba, misewu yothamanga ndi madera ena.
Gulu Lachisanu: (Mtundu wocheperako wa E600 uyenera kusankhidwa): Malo otumizira katundu, malo ofikirako katundu, mabwalo a ndege ndi madera ena.
Gulu 6: (Kusankha kochepa kwa mtundu wa F900): Malo ochitira maseŵera a pa eyapoti ndi madera ena.
