Description

Technical Field

[0001] The present invention relates to the technical field of port engineering, and particularly to a rain and sewage collection system applied to wharves and approach bridges. More specifically, it is a structure of a wharf, approach bridge and drainage ditch that can reduce project investment and workload when collecting rain and sewage on the wharf and approach bridge. Background Art

[0002] During the operation of the wharf, a large amount of polluting gases such as acidic gases, vehicle exhaust gases, and factory waste gases will be generated. In the initial stage of rainfall, rainwater will dissolve a large amount of polluting gases in the air. After falling to the ground, due to the washing of the roof and road surface, the pollution degree of the early-stage rainwater in the wharf area is relatively high. If the early-stage rainwater is directly drained into the natural receiving water body, it will cause obvious pollution to the environment. Therefore, it is necessary to collect the rain and sewage in the wharf area.

[0003] In the traditional rain and sewage collection system, drainage open ditches are usually set on the wharf and approach bridge surfaces, sewage collection pools are set at certain intervals, and lift pumps are set in the sewage collection pools. The rain and sewage are transported to the land area for treatment by the water pump under pressure flow. However, in the traditional rain and sewage collection system, the settings of drainage ditches, sewage collection pools, water pumps, and pressure-flow sewage pipes will cause the drainage ditches, sewage collection pools, and sewage pipes to be blocked by sediment such as coal and ore after the rainy season, and a large amount of manual cleaning is required. The cleaning is difficult and affects the drainage capacity.

[0004] Chinese Utility Model Patent CN214530987U discloses a rainwater collection system for a wharf surface. This utility model drains through the drainage ditches of the wharf platform and the approach bridge set, realizes the collection and utilization of the rainwater and flushing water on the wharf surface, improves the strength and durability of the overall structure of the wharf surface, and avoids the accumulation of rainwater in the track groove at the same time.

[0005] Chinese Utility Model Patent CN215715880U discloses an automatic collection system for the initial rainwater in the port area. This utility model system includes: open ditches, pipe networks, valve wells, solenoid valves, later-stage rainwater discharge channels, catch basins, grids, later-stage rainwater discharge pipelines, water storage tanks, and sewage pipe networks, effectively collecting the initial rainwater in the port area and preventing the environmental pollution of the natural water body by the initial rainwater.

[0006] Chinese Utility Model Patent CN218027473U discloses a rain and sewage collection system for an existing high-pile beam-slab wharf. By setting drainage grooves on the surface layer of the wharf platform, installing a drainage ditch component between the rear edge of the wharf platform and the approach bridge, and setting eaves gutters, sewage collection pools, and sewage risers on the wharf platform, the problem of rain and sewage collection in the wharf reconstruction is effectively solved.

[0007] The above-mentioned technology has, to a certain extent, solved the problem of rain and sewage collection in the wharf area by proposing a rain and sewage collection system, but it has not provided a complete rain and sewage collection system applicable to wharves and approach bridges. It has not solved the problem of the drainage ditch passing through the wave wall, nor has it solved the problems of blockage and poor drainage of the drainage system after the rainy season, resulting in a large amount of cleaning and maintenance work.
