Precast concrete pipe gallery with reinforced steel cylinder

Abstract

The invention relates to a precast concrete pipe gallery with a reinforced steel cylinder, consisting of a gallery body and a gallery passage. The gallery passage is arranged in the gallery body, and the cross section of the gallery passage is square, wherein (1) two ends of the gallery body are coaxially and fixedly provided with a bearing port and a plugging port respectively; (2) the steel cylinder is coaxially embedded in the wall of the gallery body, and two ends of the steel cylinder are coaxially and fixedly mounted on the bearing port and the plugging port respectively; (3) N longitudinal bars are evenly embedded in the wall of the gallery body, N is more than or equal to 1 and less than or equal to 50, and two ends of the longitudinal bars are respectively and fixedly mounted on the bearing port and the plugging port; and (4) the gallery body is cylindrical. The invention has simple integral structure, scientific and reasonable design, convenient lifting and transportation, lower cost of raw materials and simple construction process, and is capable of effectively resisting uneven settlement.

Description

technical field [0001] The invention belongs to the field of pipe galleries, in particular to a prefabricated reinforced steel tube concrete pipe gallery. Background technique [0002] The main function of the pipe gallery is to gather gas pipes, water supply pipes, drainage pipes, reclaimed water pipes, heating pipes, and communication cables; its advantages are: excavation at one time, centralized construction, avoiding repeated excavation of the same road section. The current pipe gallery is all cast on site. The pipe gallery is a rectangular parallelepiped structure. The wall of the rectangular pipe gallery is embedded with a steel skeleton. The main construction steps include: slotting, support, precipitation, steel bar binding, and formwork , pouring concrete, maintenance, formwork removal, and backfilling; the main problems existing in the existing pipe gallery are: long forming time of the pipe gallery, cumbersome process steps, and high construction cost.

AI Technical Summary

Problems solved by technology

The current pipe gallery is all cast on site. The pipe gallery is a rectangular parallelepiped structure. The wall of the rectangular pipe gallery is embedded with a steel skeleton. The main construction steps include: slotting, support, precipitation, steel bar binding, and formwork , pouring concrete, maintenance, formwork removal, and backfilling; the main problems existing in the existing pipe gallery are: long forming time of the pipe gallery, cumbersome process steps, and high construction cost. In earthquake-prone areas, it is very easy to cause structural damage. One problem is that the current pipe gallery has poor impermeability, especially where the groundwater level is high, and it is easy to form a humid environment inside the pipe gallery, resulting in cable corrosion and short circuit of low-voltage power distribution equipment.
