Cast-in-place pile constructed at underground reinforced concrete structure and construction method of cast-in-place pile
The invention belongs to the technical field of underground engineering, and particularly relates to a cast-in-place pile constructed at an underground reinforced concrete structure and a constructionmethod of the cast-in-place pile. The cast-in-place pile constructed at the underground reinforced concrete structure comprises a manual dug hole, a plurality of manual dug hole protection walls arepoured in the manual dug hole, and a mechanical formed hole is formed in the lower side of the manual dug hole; and a reinforcement cage is further included, the reinforcement cage is arranged in themanual dug hole and the mechanical formed hole, and concrete is poured in the manual dug hole and the mechanical formed hole. The construction method of the cast-in-place pile constructed at the underground reinforced concrete structure comprises the following steps that S1, a site is leveled, and pile position paying-off is conducted; S2, a section of pile hole earthwork is excavated, and the manual hole digging protection walls are poured; S3, the step S2 is sequentially carried out downwards for multiple times; S4, mechanical drilling is adopted to reach the designed pile bottom elevation;and S5, the reinforcement cage is lowered, and concrete is poured. According to the cast-in-place pile constructed at the underground reinforced concrete structure and the construction method of the cast-in-place pile, the occupied construction site is small, and the more economical efficiency is achieved.
本发明属于地下工程技术领域，具体涉及一种地下钢筋混凝土结构处施作的灌注桩及其施工方法。一种地下钢筋混凝土结构处施作的灌注桩，包括人工挖孔，人工挖孔内浇筑有若干人工挖孔护壁，人工挖孔下侧设置有机械成孔；还包括钢筋笼，钢筋笼设置于人工挖孔和机械成孔内，人工挖孔和机械成孔内浇筑有混凝土。一种地下钢筋混凝土结构处施作的灌注桩的施工方法，包括如下步骤：S1：场地整平，桩位放线；S2：开挖一节桩孔土方，浇筑人工挖孔护壁；S3：依次向下进行若干次步骤S2；S4：采用机械钻孔至设计桩底标高；S5：下放钢筋笼，并浇筑混凝土。本发明提供了一种占用施工场地小且更加经济的地下钢筋混凝土结构处施作的灌注桩及其施工方法。
