Deep grouting reinforcing and lifting method for piled raft foundation of building structure
The invention discloses a deep grouting reinforcement lifting method for a piled raft foundation of a building, and relates to the technical field of reinforcement of the foundation of the building, comprising the following steps: acquiring settlement information of a target piled raft foundation and depth information of a stratum where a soft soil layer is located; grouting is conducted on the lower portion of a raft plate of the target piled raft foundation so that the thickness of the raft plate can be increased; connecting steel bars are arranged on the raft plate so that the raft plate can be widened along the outside, and reserved grouting holes are formed in the widened portion of the raft plate; the side, with large settlement, of the target piled raft foundation is determined on the basis of the settlement information, and building structure deviation rectification is conducted through a grouting method on the basis of the reserved grouting holes; and an original pile foundation is reinforced through a grouting method, and a pile end bearing layer is reinforced. According to the method, the differential settlement of the piled raft foundation of the building can be rectified and reinforced.
本发明公开了一种建构筑物桩筏基础深层注浆加固抬升方法，涉及建构筑物地基加固技术领域，包括：获取所述目标桩筏基础的沉降信息和软弱土层所在的地层深度信息；在所述目标桩筏基础的筏板下面注浆，以增补所述筏板的厚度；在所述筏板上设置连接钢筋，以使所述筏板沿外部进行拓宽，并在所述筏板的拓宽部位设置预留注浆孔；基于所述沉降信息确定所述目标桩筏基础的沉降较大的一侧，并基于所述预留注浆孔采用注浆的方法进行建构筑物纠偏；通过注浆方法加固原有桩基，并加固桩端持力层。本发明能够对建构筑物桩筏基础的不均匀沉降进行纠偏和加固。
