Description

Technical Field

[0001] The present application relates to the technical field of bridge deck drainage, and in particular to a highway bridge deck drainage facility. Background Art

[0002] At present, once water accumulates on the deck of a highway bridge on a rainy day, the tires of vehicles traveling at high speed on it will be affected by the accumulated water and cause them to slip and lose control, resulting in serious traffic accidents such as vehicle sliding or rollover. Therefore, drainage facilities must be installed on the deck of the highway bridge to quickly remove the water on the bridge.

[0003] With the development of social construction, on the basis of ensuring the quality of engineering construction, more and more attention is paid to the protection of the ecological environment. Therefore, more and more attention is paid to the drainage of bridges across important sensitive urban lakes with high water quality requirements. According to data, during the operation of highways or urban bridges, the pollutant composition of the initial rainwater runoff on the road surface is complex, and the bridge runoff generated by rainfall (especially the initial runoff) contains a certain amount of suspended particulate matter, organic matter, nutrients, heavy metals and other pollutants.

[0004] In the process of implementing this application, the inventors found that there are at least the following problems in this technology: normal runoff from the bridge deck will cause the water to carry pollutants such as organic matter, nutrients and heavy metals into rivers and lakes, causing water pollution. Summary of the invention

[0005] In order to reduce the pollution to water resources, the present application provides a highway bridge deck drainage facility.

[0006] The present application provides a highway bridge deck drainage facility, which adopts the following technical solution:

[0008] By adopting the above technical solution, in the early stage of bridge construction, the electromagnetic three-way valve can be switched to connect the vertical pipe with the first drain pipe. When it rains or waters, the bridge deck runoff carries suspended particles, heavy metal substances, etc. through the vertical pipe into the first drain pipe, and then enters the hazardous waste pool through the first drain pipe. When the liquid level in the hazardous waste pool is high, the bridge maintenance personnel can transport the hazardous waste liquid to other places for hazardous waste treatment, thereby reducing the discharge of pollutants into the environment and causing pollution to the environment. By setting up the diversion mechanism, the pollutants carried by the bridge deck runoff in the early stage of bridge deck construction are reduced, and the pollution to water resources caused by flowing into lakes and rivers is reduced.

[0009] Optionally, the diversion mechanism further includes an identification component, which is disposed at an end of the vertical pipe away from the first electromagnetic three-way valve, and the identification component is electrically connected to the first electromagnetic three-way valve and controls the switching of the first electromagnetic three-way valve channel.

[0010] By adopting the above technical scheme, when hazardous chemicals leak from a hazardous chemical transport vehicle passing on the bridge deck, the hazardous chemicals flow along the bridge deck into the drainage ditch, and then pass through the identification piece on the vertical pipe. The identification piece detects the signal of the hazardous chemicals and controls the switching of the electromagnetic three-way valve to connect the vertical pipe with the first drainage pipe. The hazardous chemicals then pass through the vertical pipe into the hazardous waste pool. The identification piece can be used to detect whether there are hazardous chemicals in the runoff from the bridge deck, thereby reducing the pollution of the water environment caused by hazardous chemicals flowing into lakes and rivers, and at the same time making full use of the hazardous waste pool.

[0012] By adopting the above technical scheme, when the leaked hazardous waste is a substance that is insoluble or slightly soluble in water, and the density of the substance is greater than 1, the collection pump can be started to generate suction, and the collection pump transports the hazardous waste on the water surface to the recovery pool through the collection head on the hose; through the set hazardous waste recovery component, a variety of water-soluble and water-insoluble hazardous chemicals can be separated, reducing the difficulty of handling hazardous chemicals and making the handling of hazardous chemicals more convenient.

[0013] Optionally, the recycling mechanism also includes a first waste removal component and a second waste removal component, the first waste removal component includes a first waste removal pump and a first waste removal pipe, the first waste removal pump is arranged on the hazardous waste pool, and the first waste removal pipe is connected to the hazardous waste pool through the first waste removal pump; the second waste removal component is arranged on the recycling pool and is used for recovering hazardous waste liquid in the recycling pool.

[0014] By adopting the above technical solution, when hazardous waste leaks on the bridge deck, maintenance personnel can drive the hazardous waste collection vehicle to the front, and then start the first waste pump to collect the hazardous chemicals and water in the hazardous waste pool, and at the same time use another hazardous waste collection vehicle and the second waste collection component to collect the hazardous chemicals in the recovery pool; the first waste collection component and the second waste collection component are set up to facilitate the recycling of hazardous waste.

[0015] Optionally, a waste removal mechanism is provided on the second drainage pipe, and the waste removal mechanism includes a temporary storage tank and a flushing assembly. The temporary storage tank is placed on one side of the hazardous waste tank. The flushing assembly includes a pressurizing member, a connecting pipe, a flushing pipe and a flushing head. The connecting pipe is connected and communicated with the temporary storage tank. The flushing pipe is arranged along the length direction of the bridge deck and is connected to the connecting pipe.

The flushing head is communicated with the flushing pipe through the water outlet hole and faces the bridge deck. The pressurizing member is arranged on the connecting pipe.

[0016] By adopting the above technical scheme, when the bridge deck has normal runoff, the water flows into the second drain pipe through the first electromagnetic three-way valve on the vertical pipe, and then enters the temporary storage tank for storage through the second drain pipe. When hazardous chemicals leak on the bridge deck, the pressurizing component can be started to pump out the water in the temporary storage tank, and the water flows into the flushing pipe through the connecting pipe, and then is flushed through the flushing head on the flushing pipe, thereby reducing the retention of hazardous chemicals on the bridge deck and causing pollution to passing vehicles and air. The waste removal mechanism is set up, on the one hand, it is convenient to clean up hazardous chemicals on the bridge deck, and on the other hand, the water of normal runoff can be stored and recycled, thereby reducing the waste of water resources.

[0017] Optionally, the waste removal mechanism also includes a connecting ring, an atomizing nozzle, a monitoring device and a rotating assembly. A plurality of the connecting rings are arranged on the bridge deck, and a flushing hole and an atomizing hole are opened on the connecting ring, and the plurality of connecting rings are rotatably connected to the flushing pipe; the connecting ring and the flushing pipe rotate relative to each other to realize the connection between the flushing hole or the atomizing hole and the water outlet hole; the flushing head is arranged on the connecting ring and is connected with the flushing hole, and the atomizing nozzle is arranged on the connecting ring, and the atomizing nozzle is connected with the atomizing hole; the rotating assembly is arranged on the bridge deck, and the rotating assembly is connected to the flushing pipe and drives the flushing pipe to rotate; the monitoring device is arranged on the bridge deck to monitor the bridge deck temperature, and the monitoring device is used to control the start and stop of the rotating assembly.

[0018] By adopting the above technical scheme, when the temperature is high in summer, in order to reduce the softening of the asphalt pavement caused by the high temperature, heavy vehicles passing through the bridge deck will cause rutting on the bridge deck, or the concrete pavement will be cracked. The monitoring component detects the high temperature and controls the rotating assembly to drive the flushing pipe to rotate. The water outlet on the flushing pipe is connected to the atomizing hole on the connecting ring. The water in the flushing pipe passes through the atomizing nozzle to form water mist, which is sprayed on the road surface, so that the road surface temperature is reduced, the road surface is cooled, and the water source accumulated in normal runoff is reasonably utilized at the same time; when the hazardous chemicals leaked on the bridge deck are volatile liquids, the atomized water mist helps the volatile hazardous chemicals to form droplets that fall on the road surface, thereby reducing the pollution of the air by volatile hazardous chemicals.

[0019] Optionally, the rotating assembly includes a rotating motor, a first gear and a second gear. The rotating motor is arranged on the bridge deck, the first gear key is connected to the output shaft of the rotating motor, the second gear is arranged on the flushing pipe, the first gear is meshed with the second gear, and the monitoring device is electrically connected to the rotating motor and controls the start and stop of the rotating motor.

[0020] By adopting the above technical solution, the rotating motor is started, the rotating motor drives the first gear to rotate, the first gear drives the second gear to rotate, and the second gear drives the flushing pipe to rotate, thereby realizing the switching of the water outlet and the flushing hole or the atomization hole. The set rotating component has a simple structure and is easy to operate. At the same time, it is electrically connected to the monitoring component and does not require manual operation, thereby reducing manpower loss.

[0021] Optionally, the waste removal mechanism also includes a water intake component, which includes a liquid level gauge, a second electromagnetic three-way valve, a first water intake pipe and a second water intake pipe, the second electromagnetic three-way valve is arranged on the connecting pipe, the first water intake pipe and the second water intake pipe are both arranged on the second electromagnetic three-way valve, the first water intake pipe is connected to the temporary storage tank, and the second water intake pipe is connected to a water source; the liquid level gauge is arranged on the temporary storage tank, the liquid level gauge is electrically connected to the second electromagnetic three-way valve and controls the switching of the second electromagnetic three-way valve.

[0022] By adopting the above technical solution, when the frequency of road surface cooling increases in summer and the water level in the temporary storage tank is too low, the level meter detects a signal of too low water level and controls the switching of the second electromagnetic three-way valve to connect the connecting pipe with the second water intake pipe, and then the pressurizing component starts normally. The pressurizing component transports water from lakes and rivers to the flushing pipe through the second water intake pipe, and sprays the bridge deck for cooling through the atomizing nozzle at the atomizing hole. By setting up the water intake component, the frequent road surface cooling in summer and the shortage of water caused by it are reduced, so that the cooling effect of the road surface can be maintained, and there is no need to temporarily store water in the temporary storage tank, which reduces the energy loss caused by the excessive water in the temporary storage tank being discharged from the temporary storage tank again when it rains and high temperatures alternate.

[0023] Optionally, an overflow assembly is provided on the temporary storage tank, including a buoyancy ball, a flap gate and an overflow pipe. The overflow pipe is provided on the temporary storage tank, the flap gate is rotatably provided on the overflow pipe and is located in the temporary storage tank, the buoyancy ball is provided on the flap gate, and when the liquid level drives the buoyancy ball to float up, the flap gate opens to connect the overflow pipe with the temporary storage tank.

[0024] By adopting the above technical solution, when it rains a lot in the season, rainwater enters the temporary storage tank through the bridge deck runoff, and the water level in the temporary storage tank rises. When the liquid level in the temporary storage tank is higher than the flap gate, the buoyancy ball rises and drives the flap gate to rotate. The flap gate opens the connection between the overflow pipe and the temporary storage tank, and water enters the overflow pipe and is discharged into rivers and lakes through the overflow pipe. As the liquid level drops, the buoyancy ball slowly drops, and the flap gate cuts off the connection between the overflow pipe and the temporary storage tank again. By setting up the overflow component, the probability of water accumulation on the road surface caused by the water level in the temporary storage tank being too high is reduced.

[0025] Optionally, a waste discharge mechanism is provided on the hazardous waste pool, and the waste discharge mechanism includes a guide plate, a first waste flushing component and a second waste flushing component.

[0026] By adopting the above technical solution, when removing hazardous chemicals from hazardous waste pools and recycling pools, after the hazardous chemicals in the hazardous waste pools and recycling pools are discharged, the booster pump is started, and the booster pump drives the water flow to impact the hazardous chemicals adhering to the guide plate, and the second waste flushing component is used to impact the hazardous chemicals adhering to the guide plate, thereby reducing the retention of hazardous chemicals and mixing with the hazardous chemicals in subsequent hazardous chemical leaks.

[0027] In summary, this application includes the following beneficial technical effects:

[0028] 1. In the early stage of bridge construction, the electromagnetic three-way valve can be switched to connect the vertical pipe with the first drainage pipe. When it rains or sprinkles water, the bridge runoff carries suspended particles, heavy metal substances, etc. through the vertical pipe into the first drainage pipe, and then enters the hazardous waste pool through the first drainage pipe. When the liquid level in the hazardous waste pool is high, the bridge maintenance personnel can transport the hazardous waste liquid to other places for hazardous waste treatment, reducing the discharge of pollutants into the environment and causing pollution to the environment. Through the diversion mechanism set up, the pollutants carried by the bridge runoff in the early stage of bridge construction are reduced, and the pollution of water resources caused by flowing into lakes and rivers is reduced;

[0029] 2. When hazardous chemicals leak from a hazardous chemical transport vehicle passing on the bridge deck, the hazardous chemicals flow along the bridge deck into the drainage ditch, and then pass through the identification piece on the vertical pipe. The identification piece detects the signal of the hazardous chemicals and controls the switching of the electromagnetic three-way valve to connect the vertical pipe with the first drainage pipe. The hazardous chemicals then pass through the vertical pipe into the hazardous waste pool. The identification piece can detect whether there are hazardous chemicals in the runoff from the bridge deck, thereby reducing the pollution of the water environment caused by hazardous chemicals flowing into lakes and rivers, and making full use of the hazardous waste pool.

[0030] 3. When the bridge deck is in normal runoff, the water flows into the second drain pipe through the first electromagnetic three-way valve on the vertical pipe, and then enters the temporary storage tank for storage through the second drain pipe. When hazardous chemicals leak on the bridge deck, the pressurizing component can be activated to pump out the water in the temporary storage tank, and the water flows into the flushing pipe through the connecting pipe, and then flushes through the flushing head on the flushing pipe, thereby reducing the retention of hazardous chemicals on the bridge deck and causing pollution to passing vehicles and air. The waste removal mechanism is set up to facilitate the cleaning of hazardous chemicals on the bridge deck on the one hand, and on the other hand, the water of normal runoff can be stored and recycled, reducing the waste of water resources;

[0031] 4. When the temperature is high in summer, in order to reduce the softening of the asphalt pavement caused by high temperature, heavy vehicles passing through the bridge deck will cause ruts on the bridge deck, or the concrete pavement will crack. The monitoring component detects the high temperature and controls the rotating assembly to drive the flushing pipe to rotate. The water outlet on the flushing pipe is connected to the atomizing hole on the connecting ring. The water in the flushing pipe passes through the atomizing nozzle to form water mist, which is sprayed on the road surface, thereby reducing the road surface temperature and achieving road surface cooling. At the same time, the water source accumulated in normal runoff is reasonably utilized; when the hazardous chemicals leaked from the bridge deck are volatile liquids, the atomized water mist helps the volatile hazardous chemicals to form droplets that fall on the road surface, thereby reducing the pollution of the air by volatile hazardous chemicals.

Then the identification member 260 controls the pressurizing member 421 to start, and controls the rotating motor 441 to start at the same time. The rotating motor 441 drives the flushing pipe 423 to rotate, so that the water outlet is first connected to the atomizing hole, and the water flow forms water mist and sprays toward the sky above the bridge deck, so that the hazardous chemicals volatilized into the air fall back to the bridge deck with the water mist, and then flow along the bridge deck into the hazardous waste pool 250; then the rotating motor 441 continues to rotate, so that the water outlet is connected to the flushing hole, and the water in the flushing pipe 423 is flushed on the bridge deck along the flushing head 424, so that some of the hazardous chemicals adhering to the bridge deck flow into the hazardous waste pool 250.

[0054] When the hazardous chemicals in the hazardous waste pool 250 are insoluble or difficult to dissolve in water, the collection pump 314 is started and drives the hazardous chemicals along the collection head 313 into the recovery pool 315; when hazardous chemicals leak on the bridge deck, the maintenance personnel drive the hazardous chemical collection vehicle to the bridge deck, and then start the first waste pump 321 and the second waste pump 331 to collect and transport the hazardous chemicals to other places for treatment.

[0055] When the temperature is high in summer, in order to reduce the damage caused by heating of the bridge deck, the monitoring component 430 monitors the temperature signal and controls the rotating motor 441 to start. The rotating motor 441 drives the first gear 442 and the second gear 443 to rotate, and the second gear 443 drives the flushing pipe 423 to rotate. The water outlet on the flushing pipe 423 is connected with the atomizing hole and sprays toward the bridge deck, so that the temperature of the bridge deck can be reduced. When there is less precipitation and the liquid level in the temporary storage tank 410 is too low, the liquid level meter controls the second electromagnetic three-way valve 451 to switch to the second water intake pipe 453 to connect with the connecting pipe, and the pressurizing component 421 leads the second water intake pipe 453 to take water into the flushing pipe 423 to complete the cooling of the bridge deck.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
