Prefabricated inspection pit stand column and construction method thereof
The invention discloses a prefabricated inspection pit stand column and a construction method thereof, and relates to the technical field of rail traffic inspection pits. The prefabricated inspectionpit stand column comprises a prefabricated column body, wherein the middle of the prefabricated column body is provided with a central through hole which penetrates through two ends of the prefabricated column body; the bottom end of the prefabricated column body is supported on a ground beam; the ground beam is provided with a spacing boss by corresponding to the position of the central through hole; the central through hole is clamped to the spacing boss; the reserved reinforcing steel bar of the ground beam extends into the central through hole from the bottom end of the central through hole; and in addition, the central through hole is filled with concrete mortar to enable the prefabricated column body to be fixedly connected with the ground beam. The prefabricated inspection pit standcolumn does not require on-site pouring, has a short on-site construction period and high construction accuracy.
本发明公开一种预制式检查坑立柱及其施工方法，涉及轨道交通检查坑技术领域，预制式检查坑立柱，包括预制柱体，预制柱体的中部设置有贯穿其两端的中心通孔，预制主体的底端支撑于地梁上，地梁对应于中心通孔的位置设置有限位凸台，中心通孔卡接于限位凸台上，地梁的预留钢筋自中心通孔底端伸入中心通孔内，且中心通孔内灌有混凝土砂浆，以使预制柱体与地梁固定连接的。该预制式检查坑立柱不需要现场浇筑，现场施工周期短，且施工精度高。
