Reinforcing and lifting method for building on expansive soil foundation
The invention relates to a method for reinforcing and lifting a building on an expansive soil foundation. The method comprises the steps that a curtain wall is formed, holes are drilled downwards in the periphery of a building foundation bottom plate, the holes are drilled into a non-expansive soil layer, a plurality of spaced curtain holes are formed, grouting is conducted on the curtain holes, the grouting ranges of every two adjacent curtain holes are meshed and overlapped, and the enclosed curtain wall is formed; a shallow reinforcing body is formed, a hole is drilled downwards in the top of the raft to form a reinforcing grouting hole, the shallow expansive soil foundation is subjected to grouting reinforcement, and the shallow reinforcing body is formed; horizontal lap joint reinforcement bodies are formed, and in the expansive soil layer, the multiple horizontal lap joint reinforcement bodies extending in the horizontal direction are arranged between the curtain walls on the two opposite sides; vertical pile foundation reinforcement bodies are formed, the multiple vertical pile foundation reinforcement bodies extending in the vertical direction are arranged in an array mode, and the vertical pile foundation reinforcement bodies are connected with the corresponding horizontal lap joint reinforcement bodies on the path; and lifting grouting is conducted, specifically, lifting holes are formed in the curtain wall, pressure grouting is conducted on the bottoms of the lifting holes from bottom to top, and building lifting is achieved.
本发明涉及一种膨胀土地基上建筑物加固抬升方法，包括：形成帷幕墙，在建筑物基础底板四周向下钻孔，钻至非膨胀土层中，形成多个间隔的帷幕孔，向帷幕孔内注浆，相邻两个帷幕孔的注浆范围相互咬合重叠，形成围闭的帷幕墙；形成浅层加固体，在筏板顶向下钻孔形成加固注浆孔，对浅层膨胀土地基注浆加固，形成浅层加固体；形成水平搭接增强体，在膨胀土层中，在相对的两侧的帷幕墙之间布置多个沿着水平方向延伸的水平搭接增强体；形成竖向桩基增强体，阵列布置多个沿着竖直方向延伸的竖向桩基增强体，竖向桩基增强体分别与路径上对应的水平搭接增强体交接；抬升注浆，在帷幕墙中布置抬升孔，向抬升孔底部进行自下而上的压力注浆，实现建筑物抬升。
