Device for solving hole collapse of loose soil and sand layer and construction method
The invention discloses a device for solving hole collapse of a loose soil and sand layer and a construction method, and relates to the technical field of building construction.The device comprises a plurality of gravity blocks which are spliced to form a cone frustum, a hanging rod used for controlling the gravity blocks to move downwards in a pile hole to a hole collapse area, and an extrusion head used for diffusing the gravity blocks downwards; the inner side faces of the gravity blocks are obliquely arranged from top to bottom, the extrusion head is arranged in a cone frustum shape and can be exactly inserted into the cone frustum formed by the gravity blocks, and when the extrusion head is inserted between the gravity blocks, the extrusion head moves downwards to conduct downward diffusion on the gravity blocks. According to the method, collapsed sandy soil in a pile hole can be more efficiently diffused, meanwhile, the construction cost is lower, meanwhile, due to the fact that the precast blocks are arranged, the construction time is shorter, downward construction can be continued without waiting time after construction, and the total construction period is almost not affected.
本发明公开了一种解决松散土砂层塌孔的装置及施工方法，涉及建筑施工技术领域，包括多块拼接形成圆锥台的重力块、用于控制重力块在桩孔内向下移动至塌孔区域的吊杆和用于将重力块向下扩压的挤压头，所述重力块的内侧面由上向下呈倾斜设置，所述挤压头呈圆锥台设置且刚好能够插入重力块形成的圆锥台内，所述挤压头插入重力块之间时向下移动将重力块向下扩压；本发明能够更加高效的将桩孔内坍塌的沙土进行扩压，同时施工成本更低，同时因为是预制块，施工时间更短，且施工后不需要等待时间即可继续向下施工，对总工期几乎无影响。
