Pile casing and device for static root drilling planting pile and construction method
The invention relates to the technical field of pile foundation construction, in particular to a pile casing, device and construction method.The pile casing for static root drilling pile planting comprises a rigid cylinder body and a plurality of grouting pipes, the rigid cylinder body is used for being arranged outside a precast pile in a sleeving mode, and the inner diameter of the rigid cylinder body is larger than the outer diameter of the precast pile; a plurality of grouting pipes are arranged on the rigid cylinder body, so that a grouting gap can be formed between the rigid cylinder body and the precast pile, the grouting pipes are connected to the rigid cylinder body, extend from the top end of the rigid cylinder body to the bottom end of the rigid cylinder body and are arranged at intervals in the circumferential direction of the rigid cylinder body, and each grouting pipe is connected with a plurality of grouting branch pipes; the multiple grouting branch pipes are arranged at intervals in the axial direction of the grouting pipe, one ends of the grouting branch pipes communicate with the grouting pipe, and the other ends of the grouting branch pipes are located in the grouting gaps. The static drilling rooted pile has the advantages that the construction cost is low, a gap is not prone to being generated between the precast pile and a cement soil layer, and the horizontal bearing capacity and the vertical bearing capacity of the static drilling rooted pile are further improved.
本申请涉及桩基施工的技术领域，尤其涉及一种用于静钻根植桩的护筒、装置及施工方法，用于静钻根植桩的护筒包括刚性筒体和多个注浆管，刚性筒体用于套在预制桩外，且刚性筒体的内径大于预制桩的外径，以使刚性筒体与预制桩之间可形成注浆间隙，多个注浆管均连接于刚性筒体上，注浆管从刚性筒体的顶端朝向刚性筒体的底端延伸，多个注浆管沿刚性筒体的周向间隔设置，每个注浆管上均连接有多个注浆支管，多个注浆支管沿注浆管的轴向间隔设置，注浆支管的一端与注浆管连通，注浆支管的另一端位于注浆间隙内。本申请具有施工成本低，不易使预制桩与水泥土层间产生间隙，进一步提高静钻根植桩的水平承载力和竖向承载力的效果。
