Njira yomangira khoma la pansi pa nthaka pogwiritsa ntchito diaphragm: Njira yomangira ya SMW, njira yomangira ya TRD, njira yomangira ya CSM

Khoma losalekeza la SMW (Soil Mixing Wall) linayambitsidwa ku Japan mu 1976. Njira yomangira SMW ndi kuboola mpaka kuzama kwina m'munda pogwiritsa ntchito chosakanizira cha multi-axis. Nthawi yomweyo, cholimbitsa simenti chimapopedwa pa chobowolacho ndikusakanikirana ndi nthaka ya maziko mobwerezabwereza. Kapangidwe kolumikizana ndi kolumikizana kamagwiritsidwa ntchito pakati pa gawo lililonse lomanga. Limapanga khoma losalekeza komanso lokwanira, lopanda malumikizano pansi pa nthaka lokhala ndi mphamvu ndi kuuma kwina.

Njira yomangira TRD: Kudula ngalande Kusakanizanso khoma lakuya (Kudulanso ngalande Kusakanizanso khoma lakuya) Makinawa amagwiritsa ntchito bokosi lodulira lokhala ndi mutu wodulira unyolo ndi chitoliro cholumikizira pansi kuti adule mozama komanso mopingasa, ndipo amachita kayendedwe kokwera ndi kutsika kuti asunthe mokwanira, pomwe akulowetsa simenti coagulant. Pambuyo pokonza, khoma lofanana la simenti ndi nthaka limapangidwa. Ngati zinthu zapakati monga chitsulo chooneka ngati H zilowetsedwa mu ndondomekoyi, khoma lopitirira likhoza kukhala njira yatsopano yomangira madzi ndi ukadaulo womangira nyumba woletsa kusefukira womwe umagwiritsidwa ntchito pakhoma losunga nthaka komanso loletsa kusefukira kapena khoma lonyamula katundu mu ntchito yofukula.

Njira ya CSM: (Kusakaniza Dothi Lodula) Ukadaulo wosakaniza mozama: Ndi zida zatsopano zomangira khoma la pansi pa nthaka pogwiritsa ntchito zida zoyambira za makina odulira hydraulic groove ndi ukadaulo wosakaniza mozama, kuphatikiza ndi mawonekedwe aukadaulo a zida zodulira hydraulic groove ndi gawo logwiritsira ntchito ukadaulo wosakaniza mozama, zidazi zimagwiritsidwa ntchito pazinthu zovuta kwambiri za geological, komanso posakaniza dothi lokhazikika ndi simenti pamalo omangira. Kupanga khoma loletsa kusefukira, khoma losungira, kulimbitsa maziko ndi mapulojekiti ena.
