Njira yayikulu yomangira khoma la diaphragm: Njira yomangira ya SMW, njira yomangira ya TRD, njira yomanga ya CSM

Khoma losalekeza la SMW(Soil Mixing Wall) linayambitsidwa ku Japan mu 1976. Njira yomangira ya SMW ndikubowolera mozama m'munda ndi chosakanizira chobowola chamitundu yambiri. Panthawi imodzimodziyo, kulimbikitsa simenti kumapopera pobowola ndikusakaniza ndi nthaka ya maziko mobwerezabwereza. Zomangamanga zophatikizika ndi zopindika zimatengedwa pakati pa gawo lililonse lomanga. Zimapanga khoma losalekeza komanso lokwanira, lopanda mgwirizano pansi pa nthaka ndi mphamvu zina ndi kuuma.

Njira yomangira ya TRD: Kudula ngalande Kusakanizanso njira ya khoma lakuya (Kudula ngalande kusakanizanso njira yothira khoma) Makinawa amagwiritsa ntchito bokosi lodulira lomwe lili ndi mutu wodulira unyolo ndi chitoliro cholowera pansi kuti adulire mozama komanso kudula modutsa. , ndipo imayenda mmwamba ndi pansi kuti igwedezeke, ndikubaya simenti coagulant. Pambuyo pochiritsa, khoma lofanana la simenti-dothi limapangidwa. Ngati zida zapakati monga chitsulo chooneka ngati H chayikidwapo, khoma lopitilira litha kukhala malo atsopano oyimitsa madzi komanso ukadaulo wopangira ma anti-seepage omwe amagwiritsidwa ntchito posunga dothi komanso khoma loletsa-seepage kapena khoma lonyamula katundu mkati. ntchito yofukula pansi.

Njira ya CSM: (Cutter Soil Mixing) Ukadaulo wosanganikirana wakuya: Ndi njira yopangira zida zapansi panthaka za diaphragm kapena zida zomangira khoma zophatikiza zida zoyambira zamakina a hydraulic groove mphero ndi ukadaulo wosanganikirana wakuya, wophatikizidwa ndiukadaulo wa zida zamakina a hydraulic groove. ndi gawo logwiritsira ntchito luso losanganikirana kwambiri, zidazo zimagwiritsidwa ntchito pazinthu zovuta kwambiri za geological, komanso kusakaniza dothi la in-situ ndi simenti. matope pamalo omanga. Kupanga khoma la anti-seepage, khoma losungira, kulimbikitsa maziko ndi ntchito zina.
