Mulu wotalikirapo wozungulira

Kubowola kozungulira kotalikirako kumapopa ukadaulo wapamwamba kwambiri wa konkriti kumbuyo kwa khola lopangidwa ndi njira yaukadaulo yaku Japan CIP, ndi yosiyana ndi mulu wamba wobowola, imatengera kubowola kwapadera kwautali wozungulira mpaka kuya komwe kudakonzedweratu, kudzera mu dzenje, mpaka pamwamba pa mulu, ndiyeno amaika analimbitsa khola ndi mapangidwe mulu, ndi mtundu watsopano wa mulu maziko kumanga njira. Super madzimadzi konkire kuponyedwa-in-malo mulu amagwiritsidwa ntchito kwambiri, osati malire ndi mlingo wa madzi pansi, liquidity konkire ndi wamphamvu, aggregate kubalalitsidwa bwino, wononga kubowola akhoza kubowola ndi kusindikiza konkire, ntchito yosavuta, konkire kuthira liwiro mofulumira, zabwino. mulu khalidwe, kuchepetsa mtengo. Ndi imodzi mwa matekinoloje khumi apamwamba omwe akulimbikitsidwa ndi Unduna wa Zomangamanga mu 2005.
2 Makhalidwe a malamulo ogwira ntchito
2.1 Super madzimadzi konkire liquidity ndi zabwino, miyala akhoza kuyimitsidwa mu konkire popanda kumira, sangabweretse tsankho, zosavuta kuika mu khola zitsulo;
2.2 Palibe dothi lopanda kanthu pansonga ya mulu, zomwe zimalepheretsa zovuta zomangamanga monga mulu wosweka, shrinkage m'mimba mwake ndi kugwa kwa dzenje, ndipo khalidwe la zomangamanga limatsimikiziridwa mosavuta;
2.3 Kutha kwamphamvu kuvala wosanjikiza nthaka yolimba, mphamvu yonyamula katundu wa mulu umodzi, ntchito yomanga yomanga komanso kugwira ntchito kosavuta;
2.4 Phokoso lochepa, osasokoneza anthu, osafunikira chitetezo chamatope, osataya zimbudzi, kufinya dothi, malo otukuka;
2.5 Kupindula kwakukulu, ndipo mtengo wa polojekitiyo ndi wotsika kwambiri poyerekeza ndi mitundu ina ya milu.
2.6 Njira yopangira mulu wobowola wowuma-bowo imatengedwa, ndipo ndondomeko yowerengera mawerengedwe a mulu wobowola wowuma (mtengo wamtengo wapatali ndi waukulu kuposa wa mulu wamatope wobowoledwa ndi wocheperapo kuposa mulu wa precast. ).
3 Kuchuluka kwa ntchito
Njira imeneyi ndi ntchito yomanga (kapangidwe) maziko mulu ndi maziko dzenje, mozama bwino kuthandiza mulu, ntchito kudzaza nthaka wosanjikiza, silt nthaka wosanjikiza, mchenga wosanjikiza nthaka ndi nsangalabwi wosanjikiza, komanso ntchito mitundu yonse ya nthaka wosanjikiza ndi madzi apansi, ukhoza kuwunjika pansi pa mikhalidwe yoyipa ya nthaka monga wosanjikiza wa nthaka yofewa ndi mchenga wa quicksand. Kutalika kwa mulu nthawi zambiri kumakhala 500mm ~ 800mm.
4 Mfundo ya ndondomeko
Mulu wa konkriti wamadzimadzi wapamwamba kwambiri umabowoleredwa ndi chobowolera chomangira chakutali mpaka pamalo okwera. Pambuyo pobowola, dzenje la konkire lomwe limayikidwa mu kubowola kwa chitoliro chamkati limakanikizidwa kuti mudzaze konkriti yapamwamba kwambiri yamadzimadzi pamtunda wapamwamba wa mulu wa mapangidwe, ndikuchotsa chitoliro chobowola kukanikizira khola lachitsulo mu muluwo. Pamene konkire yapanikizidwa pamwamba pa mulu, konkire yotsanuliridwa iyenera kukhala 50cm pamwamba pa mulu kuti zitsimikizire mphamvu ya konkire pamwamba pa mulu.
