By providing a plurality of the drain pipes 110 on the bridge floor, wherein the plurality of the drain pipes 110 are provided at equal intervals at the low side of the bridge floor cross slope of the bridge, the gate cover 120 covers the opening of the drain pipe 110, and the diameter of the opening of the drain pipe 110 is less than or equal to 200 mm. The diameter of the drain pipe 110 in the bridge drain system 100 can be obviously reduced, the use amount of pipe hanging materials is reduced, the cost is saved, and meanwhile, the influence on the integral attractiveness of the bridge is reduced due to the reduction of the pipe diameter.

Specifically, referring to fig. 1, in a possible implementation manner, the drain pipe 110 includes a collecting section 111 and a straight pipe section 112, the collecting section 111 is funnel-shaped, an opening of the drain pipe 110 is a water inlet of the collecting section 111, and a diameter of the opening of the drain pipe 110 is 180 mm. The straight pipe section 112 is fixedly connected with the collecting section 111, and the collected sewage is discharged into the straight pipe section 112, wherein the diameter of the straight pipe section 112 ranges from 90mm to 110 mm. Preferably, the diameter of the straight pipe section 112 is 90mm, the pipe wall thickness is 2mm, the straight pipe section 112 with a small pipe diameter and the water inlet with a small diameter are arranged, so that the pipe hanging difficulty is reduced, meanwhile, the pipe hanging cost is reduced, and the attractiveness is not influenced. In addition, the collecting section 111 and the straight pipe section 112 of the drain pipe 110 can be an integrally formed structure. The integrally formed structure makes the drain pipe 110 more robust and less prone to water leakage.

Further, in another possible implementation manner, the straight pipe section 112 of the drain pipe 110 and the collecting section 111 may be connected in an adhesion manner, wherein the straight pipe section 112 is sleeved at the water outlet of the collecting section 111, and the collecting section 111 and the straight pipe section 112 are sealed by using a building sealant.

It should be noted that the interval between the drain pipes 110 is set according to the rainfall at the place where the bridge is located, and the drain pipes 110 can be arranged densely in the area with much rainfall (the annual rainfall is 800mm or more), so as to increase the drainage. If the rainfall in the area is small (annual rainfall is 400mm or less), the interval between the drain pipes 110 is set to be large.

Further, referring to fig. 1, in a possible implementation manner, the pipe diameter of the joint of the collecting section 111 and the straight pipe section 112 is equal to the hole diameter of the hanging hole formed in the bridge, so that the drain pipe 110 can be clamped in the hanging hole. The anti-corrosion agent is arranged at the position where the drain pipe 110 is attached to the hanging part 130, so that the anti-corrosion agent can protect acidic, alkaline and other corrosive liquids in rainwater, and the polysulfide building sealant is coated around the upper opening of the drain pipe 110 to improve the sealing property at the interface of the drain pipe 110.
