Grouting reinforcement method for preventing foundation liquefaction
The invention discloses a grouting reinforcement method for preventing foundation liquefaction, which relates to the technical field of foundation reinforcement, and comprises the following steps: drilling a to-be-reinforced foundation according to a matrix arrangement mode to obtain a plurality of grouting holes; a grouting iron pipe is inserted into the ecological bag, and the two ends of the ecological bag are tightened to form an integrated grouting structure; the integrated grouting structures are inserted into the multiple grouting holes correspondingly; and a grouting pipe in the integrated grouting structure communicates with a grouting pump, and grouting is conducted on the multiple grouting holes according to the preset grouting sequence. The grouting reinforcement method provided by the invention combines the common advantages of piling and reinforcement, is simple in construction, has a good treatment effect on prevention of foundation soil liquefaction, and relieves the technical problem of low soil body strength of a traditional reinforcement method.
本发明公开了一种预防地基液化的注浆加固方法，涉及地基加固技术领域，包括：在待加固地基上按照矩阵排布方式进行钻孔，得到多个注浆孔；将注浆铁管插入生态袋内，并在生态袋两端扎紧形成一体化注浆结构；将一体化注浆结构分别插入多个注浆孔内；将一体化注浆结构内的注浆管与注浆泵连通，并以预设注浆顺序对多个注浆孔进行注浆。本发明提供的注浆加固方法结合了打桩及加筋的共同优点，施工简单，对预防地基土液化具有良好的治理效果，缓解了传统的通过加筋方式进行加固的方法土体强度低的技术问题。
