Abstract

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.

Description

technical field [0001] The invention relates to the technical field of rail transit inspection pits, in particular to a prefabricated inspection pit column and its installation method. Background technique [0002] Urban rail transit parking lots and depots have the function of parking and maintenance, and the pillar inspection pit is the main place for train parking and inspection. The train load acts on the track and is transmitted to the ground beams through the columns. [0003] The current inspection pit columns are usually cast-in-place concrete columns. During on-site construction, the steel bars reserved for the ground beams are connected with the column reinforcement cages, and the surrounding formwork is cast-in-place concrete. Due to the need for on-site pouring, the on-site construction period of the columns is long, which is not conducive to multi-disciplinary construction cooperation on site, and the poor construction accuracy of on-site pouring is not conduci...
