The bridge deck is usually drained by combining drainage ditches and drainage pipes on both sides of the bridge deck.

In the prior art, the bridge deck drainage system now mostly adopts drainage pipes installed on the crash walls on both sides of the bridge cross section or under the sidewalk. After the rainwater flows out of the drainage pipe, it is either discharged directly to the ground, or connected to the bridge pier along the longitudinal drainage pipe of the beam body, and discharged into the ground ditch along the downward drainage pipe. Since the water on the bridge deck flows through the inclined surface, when the rainfall is large, it is difficult to discharge the water in time through the autonomous flow of water, and water accumulation is prone to occur. At the same time, the bridge deck contains a certain amount of dust and a small amount of gravel. The dust and gravel on the bridge deck enter the drainage pipe and easily block the drainage pipe, thereby causing a decrease in the drainage rate of the bridge deck.

Therefore, it is necessary to invent a bridge deck drainage pipe structure to solve the above problems.

The utility model provides a bridge deck drainage pipe structure as shown in Figures 1 to 3, including a bridge body 1, a bridge seat 2 is fixedly connected to the bottom of the bridge body 1, a plurality of bridge piers 3 are fixedly connected to the bottom of the bridge seat 2, and the plurality of bridge piers 3 are distributed in a linear array, and water storage tanks 4 are opened on both sides of the top of the bridge body 1, and filter plates 5 are fixedly connected to both sides of the inner wall of the water storage tank 4;

The bridge pier 3 plays a supporting role.

The bridge seat 2 plays a connecting role.

The filter plate 5 is made of metal and is used for preliminarily filtering larger stones to prevent the larger stones from entering the drainage pipe body 6 .

A drainage component is provided inside the water storage tank 4, and the drainage component includes a drainage pipe body 6. There are multiple drainage pipe bodies 6, and the multiple drainage pipe bodies 6 are distributed in a linear array. The multiple drainage pipe bodies 6 cooperate with each other to discharge the water in the water storage tank 14 at the same time. The drainage pipe body 6 is fixedly connected to the water storage tank 4, and a fixing ring 12 is fixedly connected to the inner wall of the drainage pipe body 6, and an air bag 11 is fixedly connected to the top of the fixing ring 12, and a support block 10 is fixedly connected to the top of the air bag 11. A plurality of drainage grooves 14 are opened at the outer circle of the drainage pipe body 6, and the plurality of drainage grooves 14 are distributed in a circular array. Air pumps 7 are fixedly connected to both sides of the bridge body 1, and a connecting hose 8 is fixedly connected to the side of the air pump 7 close to the drainage pipe body 6. The connecting hose 8 runs through the interior of the bridge body 1 and the drainage pipe body 6, and is fixedly connected to the interior of the air bag 11.

The air pump 7 provides gas to the interior of the airbag 11 .

The connecting hose 8 is made of rubber material and has a stretching effect.

The fixing ring 12 plays a supporting role and is used to support and fix the airbag 11 .

The airbag 11 is in a ring shape, and when the airbag 11 is inflated, the support block 10 can move vertically upward.

The support block 10 is in a circular ring shape, and a middle area of the support block 10 is provided for water to flow.

A plurality of drainage slots 14 are located at the bottom of the drainage pipe body 6 , and water at the bottom of the water storage tank 4 can directly enter the water outlet pipe 15 through the drainage slots 14 for discharge.

The utility model is provided with a drainage component, through which the air bag 11 can be inflated and expanded to make the support block 10 move vertically upward. At this time, the support block 10 is higher than the water surface. When the support block 10 moves downward, a vortex is generated at the position of the drainage pipe body 6, which can speed up the discharge of water in the water tank 4 and avoid the accumulation of water in the water tank 4.

When a vortex is generated at the position of the drainage pipe body 6, on the one hand, the flow of water is accelerated, and on the other hand, solid impurities floating on the water surface can be brought into the filter screen 9, which helps to collect the solid impurities and then clean them through the filter screen 9.

Furthermore, the drainage component can speed up the flow of water and avoid water accumulation. Specifically, the air pump 7 is electrically connected to the power supply first, and the air pump 7 delivers gas to the interior of the airbag 11 through the connecting hose 8, so that the airbag 11 is inflated and expanded, driving the support block 10 to move vertically upward.

A water outlet pipe 15 is fixedly connected to the bottom of the drainage pipe body 6 , and the water outlet pipe 15 runs through the interior of the bridge body 1 .

Considering that the stones on the bridge surface enter the drainage pipe body 6 through the water with a certain impact force, causing damage to the inner wall of the drainage pipe body 6, the filter screen 9 adopts a mesh design to reduce the impact force of the stones in the water.

The end of the filter screen 9 is manufactured and installed with magnetic block material, and the support block 10 is made of iron. Therefore, the end of the filter screen 9 can be adsorbed on the support block 10. During installation, the filter screen 9 can be used by directly placing it. During disassembly, the filter screen 9 can be disassembled and cleaned by an external force greater than the magnetic force of the magnetic block.
