The second half uses clean water to wash and rinse the car, constituting a primary water wash. After washing, the water flows into a primary collection tank. The water entering the primary collection tank contains a high amount of floating grease and sand. Therefore, water from the middle is taken and flows through a water pipe into a sedimentation tank within a water circulation pool. After entering the sedimentation tank, floating grease is filtered out by a grease filter. The water then enters the middle pool where sand and gravel are filtered out by a sand and gravel baffle, resulting in secondary water entering the clean water tank. Since the water pump is located in the clean water tank, it supplies water for the first half of the car wash. This utility model achieves water recycling, saving water consumption and reducing car washing costs. Attached Figure Description

[0016] The present invention provides a water-saving foundation structure for a tunnel car wash machine, as shown in the following figure. Figure 1 as well as Figure 3 As shown, the structure includes a foundation surface 5, on which a secondary washing pool 1 and a primary washing pool 2 are connected. A sedimentation tank 3 is located on the surface of the foundation surface 5 and on one side of the secondary washing pool 1, and the sedimentation tank 3 is connected to the secondary washing pool 1. The slope of the secondary washing pool 1 from the inside to the sedimentation tank 3 is 1.7 degrees. A drain pipe 11 is installed on the surface of the sedimentation tank 3 and is connected to the municipal sewer system. The drain pipe 11 is a DN100 PVC pipe buried 500mm deep.
[0017] During implementation, the first half of the car wash utilizes a secondary water wash. After the water wash, the car enters the secondary water wash tank 1, then flows into the sedimentation tank 3, and finally flows into the municipal sewer through the drain pipe 11.
[0018] Furthermore, such as Figure 2 as well as Figure 3 As shown, a primary water collection tank 4 is provided on the surface of the foundation surface 5 and on one side of the primary washing tank 2, and the primary water collection tank 4 is connected to the primary washing tank 2. A conveyor mounting plane 51 is placed on the surface of the foundation surface 5. The conveyor mounting plane 51 is used for the transportation of vehicles, and the conveyor mounting plane 51 is located directly above the secondary washing tank 1, the primary washing tank 2, the sedimentation tank 3 and the primary water collection tank 4. The slope of the primary washing tank 2 from the inside to the primary water collection tank 4 is 1.7 degrees.
[0019] During implementation, the second half of the car wash is a single water wash. After the water wash, the water flows into the primary water collection tank 4 through the primary water washing tank 2. The water entering the primary water collection tank 4 has a lot of grease floating on the surface and a lot of sand and gravel at the bottom.
[0020] Furthermore, such as Figure 1 as well as Figure 2As shown, a water circulation tank 13 is provided on one side of the primary water collection tank 4. A grease filter screen 9 and a sand and gravel baffle 10 are installed on the inner wall of the water circulation tank 13. The depth of both the sedimentation tank 3 and the primary water collection tank 4 is 1000mm. A 170mm thick C20 plain concrete pad is laid on the inner surface of the water circulation tank 13. The vertical distance from the bottom of the grease filter screen 9 to the pad in the water circulation tank 13 is 300mm. The interior of the water circulation tank 13 is separated by the grease filter screen 9 and the sand and gravel baffle 10 into a sedimentation tank 6 and a clear water tank 8. The primary water collection tank 4 and the sedimentation tank 6 inside the water circulation tank 13 are connected to each other by a water supply pipe 12, which is a DN110 PVC pipe buried 700mm deep. A water pump 81 is installed inside the clear water tank 8. The water pump 81 is used to supply water for washing the front half of the car.
[0021] During implementation, intermediate water is taken from the water pipe 12 and flows into the sedimentation tank 6 in the water circulation pool 13. After entering the sedimentation tank 6, the floating grease is filtered out by the grease filter screen 9. The water then enters the intermediate pool 7 and is filtered out by the sand and gravel baffle 10. The water then enters the clear water pool 8 to obtain secondary water. Since the water pump 81 is placed in the clear water pool 8, the water pump 81 is used to supply water for the first half of the car washing.
[0022] Working principle: When washing cars in a tunnel, the front half of the car is relatively dirty at the beginning of the wash, so this utility model uses a second water wash. After the rear half of the car is washed, it is rinsed with clean water.
[0023] Specifically, the first half of the car wash utilizes a secondary water wash. After the water wash, the car enters the secondary water wash tank 1, then flows into the sedimentation tank 3, and finally flows into the municipal sewer through the drain pipe 11.
[0024] The second half of the car wash is done with clean water. The second half of the car wash is a single water wash. After the water wash, the water flows into the first water collection tank 4 through the first water washing tank 2. There is a lot of grease floating on the surface and a lot of sand and gravel at the bottom of the water entering the first water collection tank 4. Therefore, the middle water is taken and flows into the sedimentation tank 6 in the water circulation tank 13 through the water supply pipe 12. After entering the sedimentation tank 6, the floating grease is filtered out by the grease filter screen 9. The water then enters the middle tank 7 and is filtered out by the sand and gravel baffle 10. The water then enters the clean water tank 8 to obtain secondary water. Since the water pump 81 is placed in the clean water tank 8, the water pump 81 is used to supply water for the first half of the car wash.
