Foundation reinforcement treatment method
The invention belongs to the technical field of project construction, and discloses a foundation reinforcement treatment method. The foundation reinforcement treatment method comprises the following steps of surveying a peripheral area of a foundation, and determining whether the foundation reinforcement property is ground reinforcement or underground reinforcement; determining a foundation weak area, and removing the foundation weak area; performing prepressing treatment on the geotechnical engineering foundation by a vacuum prepressing construction method; tamping the foundation by using a rammer, and compressing soil layer pores of the foundation in a rock-soil area; determining a reinforcement method; and performing hole drilling by a pile machine, inserting a grouting pipe with a nozzle into a preset position of a soil layer, and performing foundation reinforcement by a high-pressure jet grouting method. The foundation reinforcement treatment method provided by the invention has the advantages that the vacuum prepressing treatment method is reasonably used; pore water in the rock-soil body of the foundation is enabled to be rapidly discharged; the solidification time of the soil body is obviously shortened; the foundation reinforcement quality is enhanced; through the high-pressure jet grouting treatment, the bearing capacity of the geotechnical engineering foundation is enabled to be obviously improved; and the foundation reinforcing effect is better.
本发明属于项目施工技术领域，公开了一种地基加固处理方法，所述地基加固处理方法包括：进行地基周边区域的勘察，确定地基加固性质为地面加固或地下加固；确定地基软弱区域并进行地基软弱区域的清除；采用真空预压施工方法对岩土工程地基进行预压处理；利用夯锤对地基进行夯实，对岩土地区地基土层孔隙进行压缩；确定加固方法；利用桩机钻孔，把带有喷嘴的注浆管插至土层的预定位置，采用高压喷射注浆法进行地基加固。本发明提供的地基加固处理方法，合理运用真空预压处理方法，保证地基岩土体中的孔隙水快速排出，显著缩短土体的固结时间，强化地基加固质量；高压喷射注浆处理能够保证岩土工程地基承载力得到显著提升，地基加固效果更好。
