Foundation treatment method for replacing deep backfill gravel soil lower sludge layer through high-pressure steam
The invention belongs to the field of civil engineering foundation treatment, and particularly relates to a foundation treatment method for replacing a deep backfill gravel soil lower sludge layer through high-pressure steam. In a site where sludge is accumulated, under the conditions that the thickness of an overlying gravel soil layer is 10-20m and the thickness of a lower sludge layer is 3-5m,high-pressure steam equipment is used for injecting the high-pressure steam into the sludge layer, the sludge is cut, stirred and diluted through the high-pressure steam and sprayed out of the groundsurface along a guide pipe under high pressure, and therefore deep sludge is replaced and removed. According to the method, on the premise that the overlying soil layer is not treated, the sludge layer with the thickness being 10-20m or below of the deep overlying gravel soil layer is directly replaced, and the method has the advantages of being obvious in treatment effect, simple in process, lowin cost, short in construction period, capable of saving materials, environmentally friendly and the like.
本发明属于土木工程地基处理领域，具体是一种高压水气置换深厚回填碎石土下淤泥层的地基处理方法。在堆积淤泥的场地，已上覆碎石土层厚度10‑20m以及下伏淤泥层3‑5m厚的情况下，用高压水气设备将高压水气注入淤泥层，通过高压水气将淤泥切割搅拌稀释，并在高压下沿导管喷出地表，从而达到深层淤泥被置换清除。本发明可在不处理上覆土层的前提下，直接对深厚上覆碎石土层10‑20m以下的淤泥层进行直接置换处理，具有处理效果明显、工艺简单、费用较低、工期短、节材环保等优点。
