Precast pile with pile cap and construction method of precast pile
The invention relates to a precast pile with a pile cap and a construction method of the precast pile. A precast pile with a pile cap comprises a pile body and the pile cap arranged at the top end of the pile body, a prestressed reinforcement cage and an anchoring reinforcement cage are embedded in the pile body, one end of the prestressed reinforcement cage is flush with the top end of the pile body, the anchoring reinforcement cage is connected to the prestressed reinforcement cage and extends out of the center of the top end of the pile body, and a through hole is formed in the pile cap. The pile cap is connected with the prestressed reinforcement cage through a bolt. The invention discloses a construction method of a precast pile with a pile cap. The construction method comprises the following steps: S1, manufacturing a prestressed reinforcement cage and an anchoring reinforcement cage; s2, the prestressed steel bar is tensioned; s3, a pile body is poured, and meanwhile a pile cap is manufactured; s4, the pile body and the pile cap are assembled into a finished product; s5, the pile body is detected and transported; s6, pile sinking construction is conducted; s7, earth excavation is conducted; and S8, the pile cap is dismantled. Under the condition that the anchoring effect of the precast pile and the bearing platform is guaranteed, the construction efficiency is improved, and the construction cost is reduced.
本申请涉及一种带桩帽的预制桩及该预制桩的施工方法。一种带桩帽的预制桩，其包括桩体和设置在桩体顶端的桩帽，桩体内部预埋有预应力钢筋笼和锚固钢筋笼，预应力钢筋笼一端与桩体的顶端齐平，锚固钢筋笼连接在预应力钢筋笼上，锚固钢筋笼延伸出桩体顶端中心位置，桩帽上开设有通孔，桩帽通过螺栓与预应力钢筋笼连接。一种带桩帽的预制桩施工方法，包括如下步骤：S1、制作预应力钢筋笼和锚固钢筋笼；S2、对预应力钢棒进行张拉；S3、浇筑桩体，同时制作桩帽；S4、将桩体和桩帽拼装成品；S5、对桩体进行检测、运输；S6、沉桩施工；S7、土方开挖；S8、拆除桩帽。本申请在保证预制桩和承台的锚固效果的情况下，提升施工效率，降低施工造价。
