Abstract

The utility model discloses a take bridge floor ponding prevention water drainage system of anticollision wall, including the drain pipe that distributes on anticollision wall, bridge deck pavement, girder and the anticollision wall, the water inlet setting of drain pipe is in bridge deck pavement's top. The utility model discloses a set up the wash port on the anticollision wall, not carry out the over-design to current bridge drainage system, avoid the emergence of the large amount of ponding circumstances of bridge floor to the water inlet of drain pipe is higher than the delivery port, and the difference in height that forms from this is favorable to ponding to discharge fast, and the direction of delivery port is outside towards the girder simultaneously, avoids ponding discharge back to wash the roof beam body.

Description

Take bridge floor ponding prevention water drainage system of crashproof wall

Technical Field

The utility model relates to a bridge engineering technical field especially relates to a take bridge floor ponding prevention water drainage system of anticollision wall.

Background

Urban bridge usually adopts and sets up the sump pit in bridge both sides, arranges to ground drainage system's drainage mode through the drain pipe, however this kind of mode drainage ability is limited, and when heavy rain, torrential rain come temporarily, urban overhead often has the bridge floor ponding phenomenon to take place, easily makes the vehicle in traveling skid, can cause the threat to vehicle and passenger's safety.

The drainage system of the urban bridge has higher requirements, not only needs to meet the drainage requirement at ordinary times, but also ensures that no water is accumulated on the bridge floor when heavy rain and heavy rain come.

The person skilled in the art is dedicated to solving the above technical drawbacks.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned defect of prior art, the technical purpose of the utility model is to solve the poor problem of current bridge floor drainage system drainage ability.

In order to achieve the technical purpose, the utility model provides a water drainage system for preventing accumulated water on a bridge deck with an anti-collision wall, which comprises the anti-collision wall, a bridge deck pavement, a main beam and drainage pipes distributed on the anti-collision wall, wherein a water inlet of the drainage pipes is arranged above the bridge deck pavement; the water inlet of the drain pipe is higher than the water outlet.

Preferably, a plurality of the drainage pipes are arranged along the bridge direction.

Preferably, the water outlet is located outside the main beam.

The utility model has the advantages that:

the utility model discloses because above-mentioned structural design, through set up the wash port on the anticollision wall, not carry out the excessive design to current bridge drainage system, avoid the emergence of the large amount of ponding circumstances of bridge floor to the water inlet of drain pipe is higher than the delivery port, and the difference in height that forms from this is favorable to ponding to discharge fast, and the direction of delivery port is outside towards the girder simultaneously, avoids ponding discharge back to wash out the roof beam body.

Drawings

FIG. 1 is a schematic structural view of a longitudinal bridge profile of the present invention;

fig. 2 is a schematic three-dimensional structure of the present invention.

In the figure: 1 crashproof wall, 2 drain pipes, 3 bridge deck pavement, 4 girder, 5 water inlets, 6 delivery ports.

Detailed Description

The conception, the specific structure and the technical effects of the present invention will be further described with reference to the accompanying drawings, so as to fully understand the objects, the features and the effects of the present invention.

Example (b):

as shown in figures 1-2, a water drainage system for preventing accumulated water on a bridge deck with an anti-collision wall comprises the anti-collision wall 1, a bridge deck pavement 3, a main beam 4 and drainage pipes 2 distributed on the anti-collision wall 1, wherein water inlets 5 of the drainage pipes 2 are arranged above the bridge deck pavement 3.

Specifically, a plurality of water discharge pipes 2 are provided along the bridge direction.

Specifically, the water inlet 5 of the water discharge pipe 2 is higher than the water outlet 6

Specifically, the water outlet 6 is located outside the main beam 4.

Through set up the wash port on the anticollision wall, carry out the over-design to current bridge drainage system, avoid the emergence of the bridge floor a large amount of ponding circumstances to the water inlet of drain pipe is higher than the delivery port, and the difference in height that forms from this is favorable to ponding to discharge fast, and the direction of delivery port is outside towards the girder simultaneously, avoids ponding discharge back to wash out the roof beam body.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.

Claims

1. The utility model provides a take ponding water drainage system is prevented to bridge floor of anticollision wall, includes drain pipe (2) that distribute on anticollision wall (1), bridge deck pavement (3), girder (4) and anticollision wall (1), its characterized in that: the water inlet (5) of the drain pipe (2) is arranged above the bridge deck pavement (3); the water inlet (5) of the water discharge pipe (2) is higher than the water outlet (6); a plurality of water discharge pipes (2) are arranged along the bridge direction; the water outlet (6) is positioned outside the main beam (4); the lower end of the water inlet (5) is higher than the upper surface of the bridge deck pavement (3).
