| 2. | Jet grouting is a foundation treatment method that a high - velocity grout , which is forced under high pressure out of a nozzle , cuts into the soil to form a cylindrical soil - cement solidification , and with the result of that the bearing capacity of the foundation is enhanced and the settlement and the differential settlement are reduced . this process is widely used in constructional engineering , highway bridge , coal mine and railway bed 旋喷注浆法可在地层深处将水泥浆液等以高压旋转冲切土体,形成水泥土圆柱加固体,构成旋喷桩复合地基,以达到加固地基,提高承载力和减少建筑物的沉降和不均匀沉降的目的,在我国建筑工程、公路桥梁、煤矿和铁路路基等建设工程中应用极为广泛。 |
