Method for breaking underground obstacle pile
The invention provides a method for breaking an underground obstacle pile. The method comprises the following steps that a foundation pit is dug, and the foundation pit is dug around the upper end ofthe obstacle pile; a pile head is chiseled away, and the pile head of the obstacle pile is chiseled away; a pile core is broken, the pile core of the obstacle pile is broken, and the pile side wall ofthe obstacle pile is reserved; the pile side wall is broken, and the pile side wall is broken; pile backfilling is carried out, and the pile core is filled; and the foundation pit is backfilled, andthe foundation pit is filled. The method is suitable for tunnel obstacle piles, other pile foundation engineering, municipal engineering and the like. The method has the advantages of an existing manual hole digging pile breaking technology, the defect that a supporting structure is newly added in an existing manual hole digging breaking scheme is overcome, and the breaking engineering amount is reduced; the construction procedures in the prior art are optimized, transverse channel horse head breaking construction is avoided, and the construction risk is reduced; and when the method is appliedto breaking the tunnel obstacle pile, shield tunneling is not affected by breaking the obstacle pile before shield construction, and the requirement for a construction site is low.
本发明提供一种破除地下障碍桩的方法，所述方法包括如下步骤：挖设基坑，在所述障碍桩上端的周围挖设所述基坑；凿除桩头，将所述障碍桩的桩头凿除；破除桩芯，破除所述障碍桩的桩芯，保留所述障碍桩的桩侧壁；破除桩侧壁，破除所述桩侧壁；桩回填，对所述桩芯进行填充；回填基坑，对所述基坑进行填充。该方法适用于隧道障碍桩、其他桩基工程、市政工程等。该方法具备现有人工挖孔桩破除技术的优点，解决现有人工挖孔破除方案新增支护结构的缺陷，减小破除工程量；优化了现有技术的施工工序，避免横通道破马头门施工，降低了施工风险；在应用于破除隧道障碍桩时，盾构施工前破除障碍桩不影响盾构掘进，且对施工场地要求较小。
