Cross connection structure of concrete pipe gallery and steel pipe gallery and construction method

Abstract

The invention discloses a cross connection structure of a concrete pipe gallery and a steel pipe gallery and a construction method, and aims to solve the technical problem of cross connection between the concrete pipe gallery and the steel pipe gallery. Holes are reserved or punched in the pipe wall of the concrete pipe gallery, the holes are reinforced through U-shaped hoop plates, the concrete pipe gallery, the replaceable steel-concrete combined pipe sections and the corrugated steel pipe gallery are tightly connected through bolt connecting pieces, and a cross connection structure of the concrete pipe gallery and the steel pipe gallery is formed. The outer-layer steel-concrete combined pipe section and the concrete pipe gallery are tightly connected through the bolt connecting piece, an isolating ring layer at a cross connecting port is formed, underground water can be effectively prevented from permeating, and it is guaranteed that the replaceable steel-concrete combined pipe section can be replaced in the pipe gallery. The structure is simple, reliable in force transmission and high in construction efficiency, standard and industrial production can be achieved, and wide-range application and popularization can be achieved.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a cross connection structure and construction method of a concrete pipe gallery and a steel pipe gallery. Background technique [0002] With the concentrated growth of my country's urban population and the continuous deepening of urban construction, the demand for underground pipelines is also growing. The traditional pipeline laying adopts the direct burial method. When it is necessary to change, repair or add new pipelines, it needs to be excavated, laid and backfilled in the already constructed urban area. The traditional direct-buried construction occupies a large area, which is easy to affect the traffic, and the original pipeline is easy to be damaged during the construction process. After backfilling, the ground needs to be restored, but the effect is often unsatisfactory, which affects the appearance of the city. Direct burial construction costs a lot and is likely ...

AI Technical Summary

Problems solved by technology

The traditional direct-buried construction occupies a large area, which is easy to affect the traffic, and the construction process is also easy to damage the original pipeline. After backfilling, the ground needs to be restored, but the effect is often not ideal, which affects the appearance of the city

Direct burial construction costs a lot and is likely to cause environmental pollution and waste of resources
