High-pressure jet grouting njira ndikubowola chitoliro chopukutira ndi nozzle pamalo okonzedweratu munthaka pogwiritsa ntchito makina obowola, ndikugwiritsa ntchito zida zopopera kwambiri kuti slurry kapena madzi kapena mpweya ukhale wothamanga kwambiri. 20 ~ 40MPa kuchokera pamphuno, kukhomerera, kusokoneza ndi kuwononga nthaka. Panthawi imodzimodziyo, chitoliro chobowolacho chimakwezedwa pang'onopang'ono pa liwiro linalake, ndipo slurry ndi dothi particles zimasakanikirana mokakamiza. slurry ikalimba, thupi lophatikizana la cylindrical (mwachitsanzo, mulu wa jet wozungulira) limapangidwa m'nthaka kuti likwaniritse cholinga cholimbitsa maziko kapena kusindikiza madzi ndi kupewa kutulutsa madzi.
Kuchuluka kwa ntchito
1. Itha kugwiritsidwa ntchito kwambiri mumatope, dothi lamatope, dothi lolumikizana, dongo la silty, silt (dothi la mchenga), dothi lamchenga, loess ndi dothi lochita kupanga m'nthaka yodzaza, ngakhale nthaka ya miyala ndi zigawo zina za nthaka.
2. Itha kugwiritsidwa ntchito ngati kulimbikitsa maziko a nyumba zomwe zilipo kale ndi nyumba zatsopano, ndipo ingagwiritsidwenso ntchito ngati maziko oletsa kuseweredwa; Angagwiritsidwe ntchito ngati miyeso kwakanthawi pomanga (monga zakuya dzenje dzenje mbali khoma kusunga nthaka kapena madzi, nsalu yotchinga madzi, etc.), Angagwiritsidwenso ntchito ngati okhazikika kumanga maziko chilimbikitso, anti-seepage mankhwala.
(3) Mukagwiritsidwa ntchito popangira maziko omwe nthaka ya peat kapena madzi apansi amawononga, pomwe madzi apansi panthaka ndi okwera kwambiri, kapena pomwe madzi akwera, kuyezetsa kuyenera kuchitidwa kuti adziwe momwe angagwiritsire ntchito.
Malinga ndi njira zosiyanasiyana za jet, zitha kugawidwa m'njira imodzi ya chubu, njira yamachubu awiri ndi njira yamachubu atatu
