DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Reference Figures 1 to 6 As shown, the utility model provides a crushed gravel base pavement, including a road base 1, a gravel seepage layer is arranged on the top of the road base 1, a pavement layer 7 is arranged on the top of the gravel seepage layer, side baffles 8 are arranged at both ends of the road base 1, the gravel seepage layer and the pavement layer 7, the side baffles 8 are opened with water holes 9, and a self-adjusting water discharge mechanism is movably arranged inside the water hole 9, a water storage tank 20 is fixedly connected to the center position of the top of both ends of the gravel seepage layer, a grate 11 is arranged on the top of the water storage tank 20, and the water storage tank 20 corresponds to and adapts to the water hole 9.

[0025] The self-adjusting water discharge mechanism arranged in the water flow hole 9 can automatically adjust its own opening size according to the height of the water flow surface in the water storage tank 20. When the water flow in the water storage tank 20 is small, the opening of the self-adjusting water discharge mechanism is small, which can meet the drainage needs of the road surface and ensure that the road surface will not accumulate water. When the flow in the water storage tank 20 is large, the opening of the self-adjusting water discharge mechanism increases, thereby increasing the drainage volume of the water flow hole 9 and accelerating the discharge of accumulated water on the road surface. The gravel seepage layer can cooperate with the self-adjusting water discharge mechanism to drain the accumulated water on the road surface. The grate 11 can prevent solid garbage on the road surface from entering the water storage tank 20 and clogging the water flow hole 9.

[0026] A further optimized solution is provided, in which the self-adjusting water discharge mechanism comprises two sliding baffles 10, the two sliding baffles 10 are slidably arranged in the water flow hole 9, a gap is left between the two sliding baffles 10, the sides of the two sliding baffles 10 that are away from each other are fixedly connected to the inner wall of the water flow hole 9 by a plurality of springs 19, the tops of the sides of the two sliding baffles 10 that are close to each other are fixedly connected to one end of a rotating shaft 13, the other end of the rotating shaft 13 is fixedly connected to an anti-slip plate 14, and a buoyancy lifting part is rotatably connected to the two rotating shafts 13 together, and the buoyancy lifting part is located in the water storage tank 20.

[0027] A further optimized solution is that the buoyancy lifting part includes two connecting rods 15, the connecting rods 15 correspond to the rotating shaft 13 one by one, the top of the connecting rod 15 is rotatably connected to the rotating shaft 13, the bottom ends of the two connecting rods 15 are rotatably connected to a fixing frame 17, and the bottom end of the fixing frame 17 is fixedly connected to a floating ball 18.

[0028] The float 18 is affected by the height of the water flow level in the water tank 20 and adjusts the opening of the two sliding baffles 10. When the water flow level in the water tank 20 is low and does not contact the float 18, the two sliding baffles 10 are close to each other and have a smaller opening under the elastic force of a plurality of springs 19. The smaller opening can meet the drainage needs of the road surface and ensure that there is no water accumulation on the road surface; when the water flow level in the water tank 20 is high and generates buoyancy on the float 18, the float 18 automatically rises under the action of the buoyancy, and pushes the two sliding baffles 10 to both sides through two connecting rods 15, so that the sliding baffles 10 overcome the elastic force of the spring 19 and form a larger opening, thereby increasing the drainage volume of the water flow hole 9 and ensuring that there is no water accumulation on the road surface.

[0029] According to a further optimized solution, a limiting rod 16 is provided on one side of the two connecting rods 15 which are away from each other. The limiting rod 16 is fixedly connected to the sliding baffle 10 and is located below the rotating shaft 13 .

[0030] The limiting rod 16 limits the connection rod 15 to ensure that the floating ball 18 rises or falls between the two connection rods 15 .

[0031] A further optimization scheme is that the gravel seepage layer includes a large gravel layer 2, the large gravel layer 2 is arranged above the road base layer 1, a first seepage layer 3 is arranged above the large gravel layer 2, a medium gravel layer 4 is arranged above the first seepage layer 3, a second seepage layer 5 is arranged above the medium gravel layer 4, a small gravel layer 6 is arranged above the second seepage layer 5, and a pavement layer 7 is arranged above the small gravel layer 6.

[0032] According to a further optimization scheme, a plurality of confluence grooves 12 are provided at the top of the first water seepage layer 3 and the second water seepage layer 5, and the plurality of confluence grooves 12 are arranged at equal intervals.

[0033] The first water-permeable layer 3 and the second water-permeable layer 5 allow the accumulated water on the road surface to infiltrate smoothly. During the infiltration process, a part of the accumulated water flows into the confluence groove 12 for centralized discharge.

[0034] According to the further optimization scheme, the gravel particle size of the large gravel layer 2 is 70-80 mm, the gravel particle size of the medium gravel layer 4 is 50-60 mm, and the particle size of the small gravel layer 6 is 10-20 mm.
