[0018] like Figure 1 to Figure 8 As shown, a high-level competition venue structure of the present invention includes a beam-slab structure 1 located at the bottom layer, a base layer 2 is arranged above the beam-slab structure 1, the base layer 2 is a sand layer, a waterproof membrane is laid on the surface of the sand layer, and the surface of the sand layer is arranged in a wavy shape, a plurality of seepage drainage pipes 6 are laid on the base layer 2, a plurality of seepage drainage holes 9 are arranged on the seepage drainage pipes 6, an anti-blocking structure 10 is arranged on the seepage drainage holes 9, a plurality of seepage drainage pipes 6 are covered with a seepage layer 3, the seepage layer 3 is a gravel layer, an isolation layer 4 is arranged above the seepage layer 3, the isolation layer 4 is a geotextile layer, a surface layer is arranged above the isolation layer 4, and the surface layer is a fiber sand surface layer 5; A drainage pipe 7 and a water supply pipe 8 are also provided between the seepage layer 3 and the base layer 2. One end of the seepage drainage pipe 6 is connected to the drainage pipe 7, and a connection control structure 12 for controlling the connection state of the seepage drainage pipe 6 and the drainage pipe 7 is provided at the connection between the seepage drainage pipe 6 and the drainage pipe 7. The excess accumulated water in the fiber sand surface layer 5 penetrates into the seepage drainage pipe 6 and is discharged into the municipal drainage network through the drainage pipe 7. The other end of the seepage drainage pipe 6 is connected to the water supply pipe 8, and the water supply pipe 8 injects water into the seepage drainage pipe 6. The water is discharged from the seepage drainage pipe 6 and penetrates upward to maintain the humidity of the fiber sand surface layer 5.

[0019] The working principle of the above technical solution is: After the rain, the water content in the fiber sand surface layer 5 is too high. At this time, water penetrates downward from the top to the bottom through the geotextile layer and the gravel layer, enters the inside of the seepage drainage pipe 6 from the seepage drainage hole 9 of the seepage drainage pipe 6, and then flows into the drainage pipe 7, and then flows to the municipal drainage network, so as to achieve efficient drainage of the horse racing venue. Of course, it is not difficult to understand that drainage ditches should also be set up in the horse racing venue to achieve surface drainage of large amounts of water. At the same time, a drainage slope should be constructed during construction to facilitate the flow and convergence of water, such as a drainage slope of 1%.

[0020] In hot weather, the moisture content in the fiber sand surface layer 5 is relatively low, and it is not suitable for horse racing activities. At this time, the water supply pipe 8 is opened and water is injected into the seepage drainage pipe 6, that is, water is discharged from the seepage drainage hole 9 and passes upward through the gravel layer and the geotextile layer into the fiber sand surface layer 5, so that the fiber sand surface layer 5 is at a suitable humidity and softness. It is not difficult to understand that a plurality of moisture content detection sensors are arranged in the fiber sand surface layer 5 to control the working state of the water supply pipe 8.

[0021] At the same time, it is not difficult to understand that the role of laying the entire waterproof membrane on the sand layer is to prevent water from penetrating into the sand layer and the beam-slab structure 1 of the underground structure, causing water leakage. At the same time, the entire waterproof membrane shell is customized, and the entire paving has no joints, which further avoids water leakage. At the same time, the advantage of the wavy surface of the sand layer is that it is convenient for the water that penetrates downward from the fiber sand surface layer 5 to be collected and then quickly discharged from the seepage drainage pipe 6 set at a low position. The setting of the geotextile layer is to prevent the fiber sand layer from moving downward, causing too much sand and gravel to enter the gravel layer, which can avoid the problem of the seepage drainage hole 9 being blocked to a certain extent.

[0022] In an operative manner, the anti-blocking structure 10 comprises a fixing seat 101, one end of which is fixed on the outer surface of the seepage and drainage hole 9, a through hole is provided in the middle of the fixing seat 101, the through hole is communicated with the seepage and drainage hole 9, a mounting tube 102 is provided in the through hole of the fixing seat 101, one end of the mounting tube 102 is detachably connected to the through hole of the fixing seat 101, and can be connected by thread, the other end of the mounting tube 102 is closed, a plurality of water guide holes 103 are provided on the surface of the mounting tube 102 close to the fixing seat 101, a piston block 105 is provided between the water guide hole 103 and the closed end of the mounting tube 102, and the piston The block 105 is slidably connected in the mounting tube 102, a connecting spring 106 is provided between the piston block 105 and the closed section of the mounting tube 102, one end of the connecting spring 106 is fixed on the closed end of the mounting tube 102, the other end of the connecting spring 106 is fixed to the middle of the piston block 105, a screen cover 104 is provided on the fixing seat 101, the mounting tube 102 is located inside the screen cover 104, a plurality of traction ropes 107 are provided in the middle of the piston block 105, one end of the traction rope 107 is fixed on the piston block 105, and the other end of the traction rope 107 passes through the water guide hole 103 and is fixed on the inner side of the screen cover 104.

[0023] The working principle of the above technical solution is: When draining the accumulated water, the accumulated water enters the water guide hole 103 from the screen cover 104, and then enters the seepage and drainage pipe 6 and is discharged outward. When water injection is needed to increase the humidity, the water supply pipe 8 injects water into the seepage and drainage pipe 6. Since the diameter of the water guide hole 103 is relatively small and the water supply pressure of the water supply pipe 8 is relatively large, and there is water pressure in the water supply pipe 8, the water pressure acts on the piston block 105, causing the piston block 105 to move upward, thereby driving the traction rope 107 to move upward, thereby pulling the screen cover 104, causing the screen cover 104 to undergo elastic deformation (preferably an elastic screen cover 104), thereby dropping the mud and sand adhered to the screen cover 104. At the same time, the sliding of the traction rope 107 in the water guide hole 103 can also clean the mud and sand in the pouring hole, thereby ensuring the smooth flow of the screen cover 104 and the water guide hole 103, thereby ensuring the seepage and drainage effect.

[0024] In one feasible embodiment, the traction rope 107 is an elastic traction rope 107, and a plurality of columnar protrusions 109 are provided on the traction rope 107, and the columnar protrusions 109 are fixed on the traction rope 107. A plurality of support springs 108 are provided between the screen cover 104 and the mounting tube 102, and one end of the support spring 108 is fixed on the mounting tube 102, and the other end of the support spring 108 is arranged in contact with the inner side surface of the screen cover 104.

[0025] The advantage of the elastic traction rope 107 is that when one traction rope 107 is blocked by mud or stones and cannot move, the traction rope 107 is elastically set, so it will not affect the upward movement of the piston block 105, and the piston block 105 can also drive the remaining traction ropes 107 to move upward, and can also clean the remaining water guide holes 103. At the same time, the setting of the columnar protrusion 109, when the traction rope 107 drives it to move in the water guide hole 103, it is blocked by mud and sand, and will push the mud and sand, thereby further improving the effect of removing the mud and sand in the water guide hole 103. The setting of the support spring 108 can expand the distance between the screen cover 104 and the installation pipe 102 to avoid improving the flow effect of water, and can also avoid the problem that the screen cover 104 is close to the installation pipe 102, resulting in the water guide hole 103 being blocked.

[0026] In an practicable manner, the on-off control structure 12 includes an inner tube 121, an outer tube 122 is provided on the outer side of the inner tube 121, one end of the outer tube 122 is closed and fixedly connected to the outer side surface of the inner tube 121, an end plate is provided on the other end of the outer tube 122, a water outlet hole 123 is provided in the middle of the end plate, a sliding block 125 is provided inside the inner tube 121, the sliding block 125 is slidably connected to the inner wall of the inner tube 121, a plurality of drainage holes 124 are provided on the wall of the inner tube 121 above the sliding block 125, and a connecting rod 125 is provided on one side of the sliding block 125 facing the water outlet hole 123. 26. One end of the connecting rod 126 is fixed on the sliding block 125, and a blocking plate 127 is provided on the other end of the connecting rod 126. The blocking plate 127 is fixed on the end of the connecting rod 126. The diameter of the blocking plate 127 is larger than the diameter of the drain hole 124. A plurality of sliding rods 1202 are provided on the edge of the blocking plate 127. One end of the sliding rod 1202 is fixed on the end plate, and a return spring 1203 is provided on the other end of the sliding rod 1202. One end of the return spring 1203 is fixed on the end of the sliding rod 1202, and the other end of the return spring 1203 is fixed on the blocking plate 127.

[0027] It is not difficult to understand that when the water supply pipe 8 supplies water, the other end of the seepage drainage pipe 6 should be closed to prevent a large amount of water from flowing into the municipal drainage network and to avoid wasting water resources. Therefore, when the water supply pipe 8 is working, under the action of water pressure (the amount of water is large, and in order to achieve water supply, a large water pressure is required to push), the sliding block 125 in the inner tube 121 will be pushed, and then the connecting rod 126 will be driven downward, and then the blocking plate 127 will block the water leakage hole 124, thereby preventing a large amount of water from being discharged from the water leakage hole 124. After the water supply is completed, the water pressure in the seepage drainage pipe 6 gradually disappears, and then under the action of the reset spring 1203, the blocking plate 127 will be lifted, and then the water leakage hole 124 will leak out, which is convenient for drainage on rainy days. It should be noted that the accumulated water that has penetrated into the seepage drainage pipe 6 does not have water pressure itself. Therefore, under the action of the reset spring 1203, the sealing plate 127 is separated from the drainage hole 124. Therefore, the infiltrated water can flow into the outer tube 122 from the water outlet 123, and then be discharged from the drainage hole 124 set on the outer tube 122.

[0028] In one feasible manner, a support plate 1205 is provided on one end of the inner tube 121 located inside the outer tube 122, and an auxiliary spring 128 is provided on the support plate 1205. One end of the auxiliary spring 128 is fixed to the sliding block 125, and the other end of the auxiliary spring 128 is fixed to the support plate 1205. The provision of the auxiliary spring 128 can further enhance the resetting effect of the sliding block 125, and enhance the separation effect of the sealing plate 127 and the drain hole 124.

[0029] In one feasible manner, a plurality of hollow through holes are provided on the support plate 1205, and the connecting rod 126 is slidably arranged in the middle of the support plate 1205. The hollow through holes of the support plate 1205 are arranged to avoid water accumulation between the sliding block 125 and the end of the inner tube 121, resulting in the problem that when water pressure acts on the sliding block 125, the sliding block 125 cannot squeeze out the water, resulting in the problem that the sliding block 125 cannot move downward.

[0030] In one feasible manner, a retaining ring 129 is provided on the inner wall of the inner tube 121 above the sliding block 125, and the retaining ring 129 is slidably connected to the inner side surface of the inner tube 121. A plurality of fixing rods 1201 are provided on the retaining ring 129, one end of the fixing rod 1201 is fixed to the inner wall of the retaining ring 129, and the other end of the fixing rod 1201 is fixed to the sliding block 125.

[0031] When the sliding block 125 moves downward, the retaining ring 129 is driven to move downward, and the retaining ring 129 that moves downward blocks all the water outlet holes 123, so that the water outlet holes 123 cannot drain water, and the water flow supplied in the water supply pipe 8 can further reduce the waste of discharge. At the same time, it is not difficult to understand that this design also has additional technical effects in the present technical solution. When the water pressure gradually increases and decreases, the retaining ring 129 will gradually move downward and upward, which can change the aperture of the water outlet hole 123 (from large to small and from small to large). When the aperture becomes smaller, the pressure and speed of the water flow jet can be increased, and the sediment in the drainage hole can be impacted, and the bonded sediment can be discharged, which also has the effect of clearing the hole.

[0032] In one practicable manner, mounting flanges 1204 are provided on the ends of the inner tube 121 and the outer tube 122, and the mounting flanges 1204 are used to connect to the ends of the seepage drainage pipe 6 and the ends of the drainage pipe 7, and a filter screen 11 can be provided on the side of the mounting flange 1204 close to the water inlet.

[0033] A construction method for a high-level competition venue structure comprises the following steps: S1. Lay a layer of sand in the construction area of ​​the basement beam-slab structure 1, and lay the surface of the sand in a wavy shape; S2. Lay a whole waterproof membrane on the surface of the wavy sand layer and lay the surface of the waterproof membrane flat; S3. Lay another layer of sand on the surface of the waterproof membrane to fully cover the waterproof membrane; S4, constructing a seepage drainage pipe 6, a drainage pipe 7 and a water supply pipe 8 on the sand layer on the surface of the waterproof membrane; S5, laying a layer of gravel on the completed seepage drainage pipe 6, drainage pipe 7 and water supply pipe 8; S6. construct a geotextile layer on the gravel layer, and the geotextile layer completely covers the gravel layer; S7.

[0034] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it.
