Bridge floor transverse drainage structure and drainage system thereof

Abstract

The invention discloses a bridge floor transverse drainage structure and a drainage system thereof and relates to the technical field of bridge construction. By means of the drainage structure and thedrainage system, the problem of water seepage discharging of bridge floor pavement is solved. According to the key points of the technical scheme, the bridge floor transverse drainage structure comprises a levelling layer on cast main girders, multiple transverse drainage leaking pipes, a waterproof layer and an asphalt concrete pavement layer. The multiple transverse drainage leaking pipes are transversely and sequentially laid on the levelling layer in the direction perpendicular to the length direction of the bridge. The multiple transverse drainage leaking pipes are connected with each other and arranged on the sides of longitudinal slope high points beside bridge expansion joints. Each transverse drainage leaking pipe is provided with a drainage channel and multiple drainage holes. The waterproof layer is arranged on the sides, away from the bridge expansion joints, of the transverse drainage leaking pipes, and the plane of the waterproof layer is arranged parallel with the bridge floor. The asphalt concrete pavement layer is laid on the transverse drainage leaking pipes and the waterproof layer after pavement of the transverse drainage leaking pipes and the waterproof layeris completed and used as the bridge floor. The bridge floor transverse drainage structure has the advantages that the drainage property is good and installation is convenient.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a bridge deck lateral drainage structure and a drainage system thereof. Background technique [0002] At present, the problem of bridge deck drainage needs to be considered in the construction of bridges. Poor drainage of bridge decks not only easily causes wheel slippage and reduces the traffic capacity of the bridge, but also may cause a series of water damage to the bridge, reducing driving safety and the service life of the bridge. . Therefore, it is necessary to set up a drainage structure. Generally, a "herringbone" cross slope is used for drainage, which can discharge rainwater and sewage on the road surface into the outfall on the outside of the bridge in time to achieve the purpose of bridge deck drainage. However, the water seepage inside the asphalt concrete pavement of the bridge deck cannot be well treated. The seepage water cannot be drained, and it sta...

AI Technical Summary

Problems solved by technology

However, the water seepage inside the asphalt concrete pavement of the bridge deck cannot be well treated. The seepage water cannot be drained, and it stays behind the expansion joint before the concrete platform is poured, and cannot be discharged effectively and in time. Under the repeated load of the vehicle, The water-soaked asphalt concrete pavement is severely damaged, affecting driving safety
