Bridge drainage system

Abstract

The invention discloses a bridge drainage system. The bridge drainage system comprises a bridge floor with a certain gradient, a water inlet and a drainage pipe, the water inlet is arranged at a low-lying position of the bridge floor, and the drainage pipe communicated with the water inlet is arranged inside a bridge and provided with a plurality of inspection holes. In the bridge drainage system, rainwater is converged into the water inlet by the aid of the bridge floor with the gradient and then is led out by the aid of the drainage pipe arranged inside the bridge. The drainage pipe arranged inside the bridge is good in durability, the problem that the drainage pipe is stolen easily is solved, and overall appearance of the bridge is improved. The inspection holes on the drainage pipe facilitate inspection, maintenance and cleaning of the internal drainage pipe. The bridge drainage system is reasonable in design and can be widely used for the field of bridge engineering.

Description

technical field [0001] The invention is used in the field of bridge engineering, and in particular relates to a bridge drainage system. Background technique [0002] For municipal and highway bridges, in order to ensure safe and unobstructed driving and prevent the bridge deck structure from being eroded by precipitation to affect the durability of the bridge, a complete bridge deck drainage system should be set up in accordance with the requirements of relevant national regulations. The design of the bridge deck drainage system is mainly Vertical and horizontal slope drainage is set on the bridge, and after the precipitation is collected, it is connected to the drainage pipe pre-buried in the beam body and pier column through the bridge deck water inlet at the low slope and introduced into the ground drainage system. In the past, due to the limited construction quality and maintenance management level, bridge drainage pipes generally adopt the method of laying exposed pipes...

AI Technical Summary

Problems solved by technology

[0003] To sum up, there are many deficiencies and shortcomings in the current bridge drainage system: the pipes of the external drainage pipes are exposed on the surface of the bridge, which affects the overall appearance of the bridge; the built-in drainage pipes have poor adaptability to the relative displacement of the upper and lower structures of the bridge , Daily maintenance and dredging are difficult, and it is inconvenient to replace when silted up
