Abstract

A kind of bridge expanssion joint guarded drainage device, including tapping pipe, drain tank, reducing tee, storm sewer, securing member, connector, drain tank is connected with tapping pipe, and reducing tee is connected with drain tank, reducing tee is connected with connector, and storm sewer is fixed on the side of pontic A by securing member；Both sides pontic A is equipped with reserved drain line C near one end of expansion joint B, described a kind of bridge expanssion joint guarded drainage device is fixed in the B of expansion joint by the anchor bar D of the drain line C of B both sides, expansion joint, is provided with for sealing the rubber sealing ring E of tapping pipe and being connected to the tapping pipe of this drain tank in described drain tank.This utility model is quickly emitted into accumulating in the rainwater at bridge expanssion joint under bridge, and the scene preventing bridge floor from leaking occurs, avoids rainwater to beam body, the corrosion function of pier, it is ensured that the durability of bridge simultaneously, is applied in traffic engineering technical field.

Description

A kind of bridge expanssion joint guarded drainage device

Technical field

This utility model relates to a kind of bridge expanssion joint guarded drainage device in traffic engineering technical field.

Background technology

At present, along with the fast development of China's economy, along with Modern Urban Development is increasingly faster, science of bridge building bridge deck drainage System now more to be taked to be located at cross-section of bridge west side anti-collision wall or footpath bottom drain pipe ejectment water, and rainwater is flowed out by drain pipe After, or it is directly discharged to ground, or draws along beam body longitudinal drainage pipe and receive bridge Dun Chu, drain into ground along downward drain pipe In ditch.Bridge beam body expansion joint be in order to avoid bridge variations in temperature when due to expand with heat and contract with cold produce temperature stress Destroying a bridge and reserved a kind of movement joint, be mostly provided with retractor device in flexible knot, retractor device is typically provided waterstop, Rainwater is stoped to leak under expansion joint by the sealing effect of waterstop, and excessive to bridge floor in the case of amassing completely, pass through bridge floor Arrange outside drainage system.But, it is limited by the feature of waterstop structure and uses the impact of environment, waterstop easily wear and rupture, Rainwater is still trickled to beam body side by expansion joint or space, two ends, expansion joint, and trickles downwards to Bridge Pier along bridge pad On, the trickling of bridge long-term rain beam body side surface not only causes bridge floor to leak, and also beam body, pier is had certain corrosion function.Cause This, research and develop the new problem that a kind of bridge expanssion joint guarded drainage device is always badly in need of solving.

Summary of the invention

The purpose of this utility model is to provide a kind of bridge expanssion joint guarded drainage device, this utility model can quickly by Accumulate in the rainwater at bridge expanssion joint to be emitted under bridge, and the scene preventing bridge floor from leaking occurs, avoids rainwater to beam simultaneously Body, the corrosion function of pier, ensure the durability of bridge.

The purpose of this utility model is achieved in that a kind of bridge expanssion joint guarded drainage device, a kind of bridge expanssion joint Guarded drainage device, including tapping pipe, drain tank, reducing tee, storm sewer, securing member, connector, water leg, anchor bar, Rubber sealing ring, is fixed on water leg on pontic A by anchor bar, and water leg is connected with rubber sealing ring and tapping pipe, Drain tank is connected with tapping pipe, and reducing tee is connected with drain tank, and reducing tee is connected with connector, by securing member by rainwater Pipeline is fixed on the side of pontic A；

Described drain tank 2 uses cast iron to make, and tapping pipe and reducing tee are made up of pvc pipe；

Described drain tank becomes funnel type, described tapping pipe to be pipe；

Described reducing tee is connected to realize socket joint with tapping pipe and storm sewer form-fit.

The structure being characterized by it of the present utility model.Its operation principle is, in pontic A, the hydrops of expansion joint B is by collection Tank enters tapping pipe, then discharges through drain tank, reducing tee, storm sewer.Bridge expanssion joint B functional in organized water drainage device can Quickly to drain rainwater in the B of expansion joint, to reduce sediment deposition, improve deck drainage system, guide bridge floor rainwater organized Discharge, makes that bridge expanssion joint B is more efficient, reasonably works, and can effectively prevent from bridge floor from leaking simultaneously avoiding rainwater to beam Body, the corrosion of bridge pier, it is ensured that the durability of bridge.

A kind of bridge expanssion joint guarded drainage device compared with prior art, has and quickly can will accumulate in bridge expanssion joint The rainwater at place is emitted under bridge, and the scene preventing bridge floor from leaking occurs, avoids rainwater to make the erosion of beam body, pier simultaneously With, it is ensured that the advantages such as the durability of bridge, will be widely used in traffic engineering technical field.

Detailed description of the invention

Referring to the drawings, a kind of bridge expanssion joint guarded drainage device, including tapping pipe 1, drain tank 2, reducing tee 3, rainwater Pipeline 4, securing member 5, connector 6, water leg 7, anchor bar 8, rubber sealing ring 9, by anchor bar 8 by solid for water leg 7 On pontic A, water leg 7 is connected with rubber sealing ring 9 and tapping pipe 1, and drain tank 2 is connected with tapping pipe 1, reducing tee 3 Being connected with drain tank 2, reducing tee 3 is connected with connector 6, and storm sewer 4 is fixed on the side of pontic A by securing member 5.

Described drain tank 2 becomes funnel type, and described tapping pipe 1 is pipe.

Described reducing tee 3 is connected to realize socket joint with tapping pipe 1 and storm sewer 4 form-fit.

The operation principle of a kind of bridge expanssion joint guarded drainage device is, in pontic A, the hydrops of expansion joint B passes through water leg 7 Enter tapping pipe 1, then discharge through drain tank 2, reducing tee 3, storm sewer 4.Bridge expanssion joint B functional in organized water drainage device can Quickly to drain rainwater in the B of expansion joint, to reduce sediment deposition, improve deck drainage system, guide bridge floor rainwater organized Discharge, makes that bridge expanssion joint B is more efficient, reasonably works, and can effectively prevent from bridge floor from leaking simultaneously avoiding rainwater to beam Body, the corrosion of bridge pier, it is ensured that the durability of bridge.
