Existing wall foundation reinforcing method
The invention discloses an existing wall foundation reinforcing method which comprises the steps that a row of high-pressure jet grouting piles are constructed in soil bodies on the two opposite sides of a foundation structure of an existing wall correspondingly, and gaps are formed between the two rows of high-pressure jet grouting piles and the two opposite sides of the foundation structure correspondingly; digging one side, close to the foundation structure, of the gap to form a fertilizer groove; a cushion layer connected to the bottom of the foundation structure is poured at the groove bottom of the fat groove; a newly-added foundation is poured on the cushion layer, and a steel bar structure of the newly-added foundation is connected to the foundation structure through embedded steel bars; and backfilling the soil body in the fertilizer groove and compacting the soil body. The problem that when foundation reinforcement is conducted on long-term buildings, the building foundations are prone to being disturbed is solved.
本发明公开了一种既有墙体基础加固方法，包括：于既有墙体的基础结构的相对两侧的土体中分别施工一排高压旋喷桩，两排高压旋喷桩与所述基础结构的相对两侧之间分别形成间隙；于所述间隙的靠近所述基础结构的一侧开挖形成肥槽；于所述肥槽的槽底浇筑连接于所述基础结构的底部的垫层；于所述垫层上浇筑新增基础，所述新增基础的钢筋结构通过植筋连接于所述基础结构；于所述肥槽中回填土体并压实。本发明解决了在对于年代长远的建筑物进行基础加固时，易扰动建筑物地基的问题。
