Method for reinforcing existing building foundation through arch bridge type grouting
The invention relates to the technical field of existing building foundation reinforcement, and provides a method for reinforcing an existing building foundation through arch bridge type grouting, which comprises the following steps: positioning grouting hole points on the surface of a building raft; first vertical drilling grouting is conducted according to part of the grouting hole points, a plurality of pier type pile foundations are formed, and the pier type pile foundations are arranged on the edge of the surface of the building raft at intervals; second-time vertical drilling grouting is conducted according to the other part of grouting hole points, and an arch-shaped arch body foundation is formed between the pier type pile foundations; inclined reinforcing bodies for connecting the bridge pier type pile foundations and the arch body foundations are arranged between the bridge pier type pile foundations and the arch body foundations; pile foundation side face supporting bodies inserted into a hard soil layer are arranged on the side faces, away from the arch body foundation, of the pier type pile foundations; and the lower foundation of the building raft is reinforced. Foundation reinforcement can be conducted on the existing building on the soft foundation, after the building foundation is reinforced, the bearing capacity of the building foundation can be improved, and differential settlement of the foundation is prevented.
本发明涉及既有建筑物地基加固技术领域，提供一种拱桥式注浆加固既有建筑物地基的方法，包括：在建筑物筏板的表面上定位注浆孔点；根据部分注浆孔点进行第一次竖直钻孔注浆，形成多个桥墩式桩基，各桥墩式桩基间隔布置在建筑物筏板表面的边缘；根据另一部分注浆孔点进行第二次竖直钻孔注浆，在各桥墩式桩基之间形成拱形的拱身地基；在各桥墩式桩基和各拱身地基之间布置连接各桥墩式桩基和各拱身地基的斜向加固体；在各桥墩式桩基背离拱身地基的侧面布置插入硬土层的桩基侧面支撑体；完成加固建筑物筏板下地基。本发明能够对软弱地基上的既有建筑物进行地基加固，建筑物地基得到加固后，能够提高建筑物地基的承载能力，防止地基的不均匀沉降。
