Broken pile treatment construction method for engineering pile in soft soil area
The invention belongs to the technical field of broken pile treatment, and relates to a soft soil area engineering pile broken pile treatment construction method which comprises the following steps: construction preparation, site leveling and hole digging center measurement; a first section of hole is dug, if encountering a pile body, the first section of hole is broken and transported out along with earthwork, and a first section of steel casing is placed after hole forming; the next section of hole continues to be explored and excavated, the next section of steel casing is placed after the hole is formed, and the diameter of the next section of steel casing is smaller than that of the previous section of steel casing; downwards probing to a pile fracture part step by step to form a complete pile hole; concrete sleeves are placed in the pile hole section by section, one section of corresponding steel casing is lifted out every time one section of concrete sleeve is placed, and pushing is sequentially carried out till all the steel casing is pulled out; placing a reinforcement cage, and pouring pile body concrete. The broken pile treatment construction method for the engineering pile in the soft soil area is low in cost, simple, convenient, feasible, safe and reliable.
本发明属于断桩处理的技术领域，涉及一种软土地区工程桩断桩处理施工工法，所述工法包括以下步骤：施工准备，场地平整，测出挖孔中心；挖第一节孔，如遇桩身则破碎，随土方运出，成孔后放置第一节钢护筒；继续下探挖下一节孔，成孔后放置下一节钢护筒，下一节钢护筒的直径小于上一节钢护筒的直径；逐级下探至桩断裂处，使完整的桩孔形成；于桩孔中逐节放置砼套筒，每放入一节砼套筒，即吊出一节相应的钢护筒，依次递推至钢护筒全部拔出；安放钢筋笼，浇筑桩身砼。本发明提供的软土地区工程桩断桩处理施工工法，其成本低廉，简便易行、安全可靠。
