Precast prestressed concrete pipe gallery with longitudinal bar

Abstract

The invention relates to a precast prestressed concrete pipe gallery with a longitudinal bar, 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; (2) N longitudinal bars are evenly and coaxially 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; and (3) the outer pipe wall of the gallery body is fixedly provided with a protecting layer, and prestressed wires are winded on the outer pipe wall of the gallery body in the protecting layer. The invention has simple integral structure, scientific and reasonable design, convenient lifting and transportation, simple construction process and lower cost of raw materials and construction, 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 prestressed longitudinal reinforced concrete pipe gallery. Background technique [0002] The current pipe gallery is all cast on site. The pipe gallery is a cuboid structure. The wall of the rectangular pipe gallery is embedded with a steel skeleton. Due to the large external pressure load, the wall of the pipe gallery is relatively thick. 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 main construction and production steps of the pipe gallery include: slotting, support, precipitation, steel bar binding, formwork, concrete pouring, maintenance, formwork removal, and backfilling. The main problems existing in the existing pipe ...

AI Technical Summary

Problems solved by technology

The main problems existing in the existing pipe gallery are: the forming time of the pipe gallery is long, the process steps are cumbersome, the construction cost is high, and it is very easy to cause structural damage in earthquake-prone areas, and the overall weight of the pipe gallery is relatively large. , transportation and construction are very inconvenient
