High-pressure jet grouting nzira ndeyekuboora pombi yegrouting ine nozzle munzvimbo yakafanotemerwa muvhu redhiri uchishandisa muchina wekudhiraivha, uye kushandisa yakakwirira-kumanikidza midziyo kuita slurry kana mvura kana mhepo ive yakakwira-pressure jet ye. 20 ~ 40MPa kubva pamuromo, kurova, kushungurudza uye kuparadza ivhu. Panguva imwecheteyo, pombi yekuchera inosimudzwa zvishoma nezvishoma pane imwe kukurumidza, uye slurry uye zvimedu zvevhu zvinosanganiswa nesimba. Mushure mokunge slurry yaoma, cylindrical consolidated body (kureva, rotary jet pile) inoumbwa muvhu kuti iwane chinangwa chekusimbisa nheyo kana kuvhara kwemvura nekudzivirira kwekudzivirira.
Chikamu chekushandisa
1. Inogona kushandiswa zvakanyanya muvhu, mucky ivhu, yakabatana ivhu, silty ivhu, silt (sub-jecha ivhu), jecha ivhu, loess uye artificial ivhu mubani rakazara ivhu, kunyange marara ivhu uye mamwe matanda ivhu.
2. Inogona kushandiswa senheyo kusimbiswa kwezvivakwa zviripo uye zvivakwa zvitsva, uye inogona kushandiswa senheyo yekudzivirira kudzivirira; Inogona kushandiswa seyenguva nhanho mukuvaka (seyakadzika nheyo gomba padivi madziro anochengetedza ivhu kana mvura, isina mvura keteni, nezvimwewo), inogona zvakare kushandiswa sechigarire chivakwa chekusimbisa nheyo, anti-seepage kurapwa.
(3) Kana ichishandiswa kurapa mapurojekiti enheyo apo ivhu repeat kana mvura yepasi iri kuita ngura, uko kuyerera kwemvura yepasi kwakakwira zvakanyanya, kana pakakwirisa mvura, bvunzo dzinofanirwa kuitwa kuti dzione kushanda kwayo.
Zvinoenderana neakasiyana nzira dzejeti, inogona kukamurwa kuita imwechete chubhu nzira, kaviri chubhu nzira uye katatu chubhu nzira
