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, curing, demoulding, and backfilling; the main problems existing in the existing pipe gallery are: the forming time of the pipe gallery is long, the process steps are cumbersome, and the construction cost is high. In earthquake-prone areas, it is very easy to cause structural damage

Abstract

The invention relates to a precast concrete pipe gallery with longitudinal bars, 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) the gallery body is cylindrical, and two ends of the gallery body are coaxially and fixedly provided with a bearing port and a plugging port respectively; and (2) N longitudinal bars are uniformly embedded in the pipe wall of the gallery body, and 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. The invention has simple integral structure and construction process, scientific and reasonable design, convenient lifting and transportation and lower manufacture cost and construction cost of the whole pipe gallery, 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 longitudinal reinforced 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 , Concrete pouring, maintenance, formwork removal, and backfilling; the main problems existing in the existing pipe gallery are: the long forming time of the pipe gallery, cumbersome process steps, high construction cost, and it i...
