Cast-in-place pile casing device, cast-in-place pile and construction method
The invention relates to the technical field of pile foundations, and discloses a cast-in-place pile casing device, a cast-in-place pile and a construction method.The cast-in-place pile casing device comprises a plurality of casing units, a plurality of connecting rings and limiting snap springs, and each casing unit is provided with more than three arc plate bodies; the multiple arc plate bodies are connected end to end around the axis of the pile casing unit in the circumferential direction to form a cylinder in an enclosing mode, the limiting clamp springs are arranged to be clamped on the inner sides of the multiple arc plate bodies and used for keeping the multiple arc plate bodies to be cylindrical, and when the limiting clamp springs are disengaged from the inner sides of the arc plate bodies, the arc plate bodies can be dislocated and separated in the radial direction. The pile casing unit designed by the invention comprises a plurality of arc plate bodies which are circumferentially distributed and surround to form a cylinder, connecting rings are mounted at two ends of the arc plate bodies, and limiting clamp springs are mounted on the inner side of the arc plate bodies, so that the pile casing unit can be structurally and stably inserted into a soil layer, and after a hole is drilled, the limiting clamp springs can release the support of the arc plate bodies from the inner side, and the arc plate bodies move towards the inner side; and the arc plate body is separated from the soil layer and can be pulled out more easily.
本发明涉及桩基技术领域，公开一种灌注桩护筒装置、灌注桩及施工方法，该灌注桩护筒装置包括多个护筒单元、多个连接环和限位卡簧，护筒单元被设置包括三个以上的弧板体，多个弧板体绕所述护筒单元的轴线在周向方向首尾连接围护形成圆筒体，限位卡簧被设置卡装在多个弧板体的内侧，用于保持多个弧板体呈圆筒体，限位卡簧从弧板体内侧脱离时，弧板体之间能沿径向方向错位分离。本发明设计的护筒单元包括多个周向分布围绕呈筒的弧板体，其两端安装连接环以及内侧安装限位卡簧，可以保持护筒单元结构稳定的被插入土层中，在钻孔之后，可从内侧使限位卡簧解除对弧板体的支撑，将多个弧板体向内侧活动，使弧板体脱离土层，更容易被拔出。
