Lime pile foundation deviation rectifying structure and construction method thereof
The invention discloses a lime pile foundation deviation rectifying structure and a construction method thereof. The method comprises the steps that 1, pile placement is conducted, specifically, measurement hole placement is conducted on an existing building foundation; 2, drilling is conducted, specifically, a steel sleeve is used for drilling a replacing and filling hole to the designed depth; 3, replacement filling is conducted, specifically, after the replacement filling holes are formed, quick lime is used for backfilling, and an embedded water injection piece is embedded in the circle center of the pile hole in the backfilling process; 4, detecting the pile: detecting the pile by adopting a cutting ring sampling method, and measuring the dry soil density of the pile; 5, pressurizing and deviation rectifying are conducted, specifically, the pre-embedded water injection piece is connected with a pressurizing pump and an air adding pump through a pipe fitting connecting piece and a guide pipe, and the foundation is transversely and longitudinally rectified; according to the method, the construction process of the lime pile can be effectively optimized by designing the pre-embedded water injection piece and the pipe fitting connecting piece, meanwhile, the lime pile is used for repairing and correcting the deviation of the foundation, the construction cost is effectively reduced, the water injection efficiency is effectively improved, and the construction process is simplified; the method has the advantages of being good in deviation rectifying effect, simple in construction process, small in foundation disturbance and low in deviation rectifying cost.
本发明公开了一种石灰桩地基纠偏结构及其施工方法，所述方法包括步骤1.放桩位：在既有建筑物地基处进行测量放孔；步骤2.钻孔：利用钢套管钻换填孔至设计深度；步骤3.换填：换填孔成孔后，使用生石灰进行回填，并在回填的过程中在桩孔圆心处埋入预埋注水件；步骤4.检桩：采用环刀取样法进行检桩，测定其干土密度；步骤5.加压纠偏：将预埋注水件通过管件连接件和导管与加压泵和加气泵连接，对地基进行横向及纵向；本方法通过对预埋注水件和管件连接件进行设计，能够有效优化石灰桩的施工过程，同时利用石灰桩对地基进行修复纠偏，有效节省了施工成本和注水效率，简化了施工过程，具有纠偏效果好、施工过程简单、对地基扰动小和纠偏成本低的特点。
