Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The first embodiment is as follows:

as shown in fig. 1, the present embodiment provides a bridge drainage system, including a drainage pipe 1 embedded in a bridge body, a water collecting hopper 2 is arranged at the top end of the drainage pipe 1, and a main water collecting pipe 7 is arranged at the top of the water collecting hopper 2; a plurality of water leakage grooves 6 are formed in the main water collecting pipe 7, and the water leakage grooves 6 are inclined downwards towards one side of the inner wall of the main water collecting pipe 7; the bottom of the water collecting hopper 2 is provided with a plurality of water collecting holes 12 communicated with the drain pipe 1, and the water collecting holes 12 incline downwards towards one side of the inner wall of the drain pipe 1; still be provided with second collector pipe 11 on the top lateral wall of drain pipe 1, the top of second collector pipe 11 sets up on the marginal inside wall of bridge.

In this embodiment, the diameter of the second water collecting pipe 11 is smaller than the diameter of the water discharging pipe 1. The lowest end of the water inlet of the second water collecting pipe 11 is flush with the upper surface of the bridge floor 5. The opening of the main water collecting pipe 7 is provided with a drainage grate 9. And a filter cup 8 is arranged in the main water collecting pipe 7. And a water filtering grille 10 is arranged at the water inlet of the second water collecting pipe 11. A plurality of second water collecting pipes 11 are arranged on the side wall of the top of the drain pipe 1, and the second water collecting pipes 11 are linearly arranged on two sides of the main water collecting pipe 7. The part of the second water collecting pipe 11 communicated with the water discharging pipe 1 is higher than the water collecting hole 12.

The bridge floor 5 is drained through the main water collecting pipe 7, after the filtering is carried out twice through the drainage grate 9 and the filtering cup 8, sewage flows into the drainage pipe 1, and sundries are accumulated on the drainage grate 9 and the filtering cup 8; when the drainage grate 9 or the filter cup 8 is blocked by the sundries, sewage mainly flows into the drainage pipe 1 through the second water collecting pipe 11, the pressure at the lower end of the second water collecting pipe 11 is smaller than that at the upper end due to the fact that the flow velocity is larger, so that the sundries blocking the main water collecting pipe 7 can be sucked to the second water collecting pipe 11, the smaller sundries pass through the water filtering grille 10 to enter the drainage pipe 1 to be discharged, the blockage of the main water collecting pipe 7 by the sundries is reduced, the diameter of the second water collecting pipe 11 is smaller than that of the drainage pipe 1, the drainage pipe 1 cannot be blocked by the sundries flowing into the drainage pipe 1 through the second water collecting pipe 11, the drainage efficiency is improved, and the water accumulated on the bridge floor 5 is greatly reduced; adsorb the inside rainwater of pontic through bridge floor 5, flow to drain pipe 1 through water leakage groove 6 and water collection hole 12, avoided the rainwater to waterproof layer 4's infiltration for a long time, avoided the rainwater to the damage of abutment 3.
