High-pressure jet grouting method is to drill a grouting pipe with a nozzle in a predetermined position in the soil layer by using a drill machine, and hoʻohana i nā mea hana kiʻekiʻe e hana i ka slurry a i ʻole ka wai a i ʻole ka ea i lilo i kiʻekiʻe-press jet o 20 ~ 40MPa mai ka nozzle, kuʻi, hoʻopilikia a luku i ka lepo. I ka manawa like, hoʻokiʻekiʻe ʻia ka paipu drill i kahi wikiwiki, a hui pū ʻia ka slurry a me nā ʻāpana lepo. Ma hope o ka paʻa ʻana o ka slurry, hoʻokumu ʻia kahi kino cylindrical consolidated (ʻo ia hoʻi, rotary jet pile) i loko o ka lepo e hoʻokō ai i ke kumu o ka hoʻoikaika ʻana i ke kumu a i ʻole ka hoʻopaʻa ʻana i ka wai a me ka pale ʻana.
Ka laulā o ka noi
1. Hiki ke hoʻohana nui ʻia i loko o ka ʻōpala, lepo lepo lepo, lepo cohesive, silty clay, silt (sub-sandy soil), one one, loess and artificial soil in the plain filled soil, even gravel soil and other soil layers.
2. Hiki ke ho'ohana 'ia e like me ka ho'oikaika 'ana i ke kahua o nā hale e noho nei a me nā hale hou, a hiki ke ho'ohana 'ia e like me ka pale 'ana i ke kahua; Hiki ke hoʻohana ʻia ma ke ʻano he hana pōkole i ke kūkulu ʻana (e like me ka pā hohonu o ka lua ʻaoʻao e mālama ana i ka lepo a i ʻole ka wai, ka pale wai ʻole, a me nā mea ʻē aʻe), hiki ke hoʻohana ʻia ma ke ʻano he hoʻoikaika paʻa hale paʻa, anti-seepage treatment.
(3) Ke hoʻohana ʻia no ka mālama ʻana i nā papahana kumu kahi e ʻino ai ka lepo peat a i ʻole ka wai lepo, kahi kiʻekiʻe o ke kahe o ka wai o ka honua, a i ʻole kahi i piʻi ai ka wai, pono e hana ʻia nā hoʻokolohua e hoʻoholo ai i kona kūpono.
E like me nā ʻano jet ʻokoʻa, hiki ke hoʻokaʻawale ʻia i ke ʻano o ka paipu hoʻokahi, ke ʻano o ka paipu pālua a me ke ʻano ʻo triple tube
