Precast prestressed concrete pipe gallery with plastic lining

Abstract

The invention relates to a precast prestressed concrete pipe gallery with a plastic lining, 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) the inner pipe wall of the gallery body is fixedly provided with the plastic lining, and the end of the bearing port and the end of the plugging port are coaxially and fixedly provided with one plastic plug respectively; 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, lower cost of raw materials and higher impermeability, 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 plastic-lined concrete pipe gallery. Background technique [0002] The current pipe gallery is all cast on site. The concrete pipe gallery is embedded with a steel skeleton. Although it can withstand external pressure loads well, its impermeability is poor, making the internal environment of the pipe gallery quite humid. Communication cables and low-voltage power distribution devices are very unfavorable, and it is easy to cause short circuits. Moreover, the on-site pipe gallery requires a long forming time, cumbersome process steps, and high construction costs. In earthquake-prone areas, it is very easy to cause structural damage. Moreover, the overall weight of the pipe gallery is relatively large. As a prefabricated component, it is very inconvenient to hoist, transport and construct.
