Squeezing and expanding structure for compaction reaming type cast-in-situ bored pile construction and construction method of squeezing and expanding structure
The invention relates to an extruding and expanding structure for compaction reaming type cast-in-situ bored pile construction, and belongs to the technical field of pile hole extruding and expanding. The extruding and expanding structure comprises a shell, a plurality of extruding and expanding plates are arranged in the shell, and through holes allowing the extruding and expanding plates to stretch out of the shell are formed in the shell; a pushing assembly used for driving the squeezing and expanding plate to stretch out of the shell and squeeze the hole wall is arranged in the shell, and the shell is connected with a rotating assembly used for driving the squeezing and expanding plate and the rotating assembly to rotate. The cast-in-place pile has the effects of improving the occlusal force of the cast-in-place pile and soil and improving the bearing capacity of the pile body.
本申请涉及一种挤密扩孔式钻孔灌注桩施工用挤扩结构，属于桩孔挤扩技术领域，其包括壳体，所述壳体内设置有若干挤扩板，所述壳体开设有供所述挤扩板伸出所述壳体的通孔，所述壳体内设置有用于带动所述挤扩板伸出壳体并挤压孔壁的推动组件，所述壳体连接有用于带动所述挤扩板和自身转动的旋转组件。本申请具有提高灌注桩与土的咬合力，提高桩身的承载力的效果。
