[0037] As Figures 1 to 8As shown in the figure, a high-level event venue structure of the present invention includes a beam-slab structure 1 at the bottom layer. Above the beam-slab structure 1, there is a base layer 2, which is a sandy soil layer. A waterproof membrane is laid on the surface of the sandy soil layer, and the surface of the sandy soil layer is arranged in a wavy shape. A number of drainage pipes 6 are laid on the base layer 2. A number of drainage holes 9 are provided on the drainage pipes 6, and an anti-blocking structure 10 is provided on the drainage holes 9. A water-permeable layer 3 is covered on a number of drainage pipes 6. The water-permeable layer 3 is a gravel layer. Above the water-permeable layer 3, there is an isolation layer 4, which is a geotextile layer. Above the isolation layer 4, there is a surface layer, and the surface layer is a fiber sand surface layer 5;

[0038] A drainage pipe 7 and a water supply pipe 8 are also provided between the water-permeable layer 3 and the base layer 2. One end of the drainage pipe 6 is connected to the drainage pipe 7, and a on-off control structure 12 for controlling the communication state between the drainage pipe 6 and the drainage pipe 7 is provided at the connection between the drainage pipe 6 and the drainage pipe 7. Excess water in the fiber sand surface layer 5 penetrates into the drainage pipe 6, is discharged into the municipal drainage network through the drainage pipe 7. The other end of the drainage pipe 6 is connected to the water supply pipe 8, and the water supply pipe 8 injects water into the drainage pipe 6, and the water is discharged from the drainage pipe 6 and penetrates upward to maintain the humidity of the fiber sand surface layer 5.

[0039] The working principle of the above technical solution is as follows:

[0040] After rain, the water content in the fiber sand surface layer 5 is too high. At this time, the water penetrates downward through the geotextile layer and the gravel layer, enters the interior of the drainage pipe 6 from the drainage holes 9 of the 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 and the like should also be set 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 collection of water, such as a 1% drainage slope.

[0041] In high-temperature weather, the water content in the fiber sand surface layer 5 is small. At this time, it is not suitable to carry out horse racing activities. At this time, the water supply pipe 8 is opened to inject water into the drainage pipe 6, that is, the water is discharged from the drainage holes 9 and penetrates 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 in a suitable humidity and softness. It is not difficult to understand that a number of water content detection sensors are arranged in the fiber sand surface layer 5 to control the working state of the water supply pipe 8.

[0042] Meanwhile, it is not difficult to understand that the function of laying a whole waterproof membrane on the sandy soil layer is to prevent water from penetrating into the sandy soil layer and the beam and slab structure 1 of the underground structure, resulting in water leakage problems. At the same time, the whole waterproof membrane shell is customized and laid without seams, further avoiding water leakage problems. At the same time, the surface of the sandy soil layer is arranged in a wavy shape, which is beneficial for the water infiltrating downward through the fiber sand surface layer 5 to gather, and then quickly drain out from the drainage pipe 6 arranged at the lower part. The geotextile layer is set to prevent the fiber sand layer from moving downward, resulting in too much sand and gravel entering the gravel layer, and can avoid the problem of blockage of the drainage holes 9 to a certain extent.

[0043] In an implementable manner, the anti-blocking structure 10 includes a fixing seat 101. One end of the fixing seat 101 is fixed on the outer surface of the drainage hole 9. A through hole is provided in the middle of the fixing seat 101, and the through hole is communicated with the drainage hole 9. An installation pipe 102 is arranged in the through hole of the fixing seat 101. One end of the installation pipe 102 is detachably connected to the through hole of the fixing seat 101, and can be connected by threads. The other end of the installation pipe 102 is closed. A plurality of water guide holes 103 are provided on the surface of the installation pipe 102 close to the fixing seat 101. A piston block 105 is arranged between the water guide holes 103 and the closed end of the installation pipe 102. The piston block 105 is slidably connected in the installation pipe 102. A connecting spring 106 is arranged between the piston block 105 and the closed section of the installation pipe 102. One end of the connecting spring 106 is fixed on the closed end of the installation pipe 102, and the other end of the connecting spring 106 is fixed in the middle of the piston block 105. A screen cover 104 is arranged on the fixing seat 101. The installation pipe 102 is located inside the screen cover 104. A plurality of traction ropes 107 are arranged 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 surface of the screen cover 104.

[0044] The working principle of the above technical solution is as follows:

[0045] When draining accumulated water, the accumulated water enters the water guide hole 103 from the screen cover 104, and then enters the drainage pipe 6 and is discharged outward. When it is necessary to inject water to increase humidity, the water supply pipe 8 injects water into the 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, there is water pressure in the water supply pipe 8. Therefore, the water pressure acts on the piston block 105, causing the piston block 105 to move upward, and then driving the traction rope 107 to move upward, and then pulling the screen cover 104, causing the screen cover 104 to undergo elastic deformation (preferably an elastic screen cover 104), and then dropping the sediment 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 sediment in the water pouring hole, thereby ensuring the smoothness of the screen cover 104 and the water guide hole 103, and further ensuring the drainage effect.

[0046] In an implementable manner, the towing rope 107 is an elastic towing rope 107. A number of columnar protrusions 109 are provided on the towing rope 107. The columnar protrusions 109 are fixed to the towing rope 107. A number of support springs 108 are provided between the screen cover 104 and the installation pipe 102. One end of the support spring 108 is fixed to the installation pipe 102, and the other end of the support spring 108 is in contact with the inner side surface of the screen cover 104.

[0047] The advantage of the elastic towing rope 107 is that when one towing rope 107 is interfered by sediment or stones and cannot move, the towing rope 107 is elastically arranged, so it will not affect the upward movement of the piston block 105. Furthermore, the piston block 105 can also drive the other towing ropes 107 to move upward, and thus the other water guide holes 103 can also be cleared. At the same time, with the arrangement of the columnar protrusions 109, when the towing rope 107 drives it to move in the water guide hole 103 and is blocked by sediment, it will push the sediment, thereby further improving the effect of removing sediment in the water guide hole 103. The arrangement of the support spring 108 can increase the distance between the screen cover 104 and the installation pipe 102, avoid improving the water flow effect, and also avoid the problem that the screen cover 104 is close to the installation pipe 102, resulting in the blockage of the water guide hole 103.

[0048] In an implementable manner, the on-off control structure 12 includes an inner pipe 121. An outer pipe 122 is provided on the outer side of the inner pipe 121. One end of the outer pipe 122 is fixedly connected to the outer side surface of the inner pipe 121 in a closed manner. A end plate is provided at the other end of the outer pipe 122. A water outlet hole 123 is provided in the middle of the end plate. A sliding block 125 is provided inside the inner pipe 121. The sliding block 125 is slidably connected to the inner wall of the inner pipe 121. A number of water discharge holes 124 are provided on the inner pipe 121 wall above the sliding block 125. A connecting rod 126 is provided on one side surface of the sliding block 125 facing the water outlet hole 123. One end of the connecting rod 126 is fixed to the sliding block 125, and a blocking plate 127 is provided at the other end of the connecting rod 126. The blocking plate 127 is fixed to the end of the connecting rod 126. The diameter of the blocking plate 127 is larger than the diameter of the water discharge hole 124. A number of sliding rods 1202 are provided at the edge of the blocking plate 127. One end of the sliding rod 1202 is fixed to the end plate, and a return spring 1203 is provided at the other end of the sliding rod 1202. One end of the return spring 1203 is fixed to the end of the sliding rod 1202, and the other end of the return spring 1203 is fixed to the blocking plate 127.

[0049] It is not difficult to understand that when the water supply pipe 8 supplies water, the other end of the infiltration drainage pipe 6 should be closed to prevent a large amount of water from flowing into the municipal drainage pipe network and avoid wasting water resources. Therefore, when the water supply pipe 8 is working, under the action of water pressure (the water volume is large, and in order to achieve water supply, a relatively large water pressure is required to push), the sliding block 125 in the inner pipe 121 will be pushed, and then the connecting rod 126 will be driven to move downward, and then the plugging plate 127 will block the water discharge hole 124, thus preventing a large amount of water from being discharged from the water discharge hole 124. After the water supply is completed, the water pressure in the infiltration drainage pipe 6 gradually disappears, and then under the action of the return spring 1203, the plugging plate 127 will lift, and then the water discharge hole 124 will be exposed, facilitating drainage on rainy days. It should be noted that the accumulated water infiltrating into the infiltration drainage pipe 6 does not have its own water pressure. Therefore, under the action of the return spring 1203, the plugging plate 127 is separated from the water discharge hole 124. Therefore, the infiltrated water can flow into the outer pipe 122 through the water outlet hole 123 and then be discharged from the water discharge hole 124 provided on the outer pipe 122.

[0050] In an implementable manner, a support plate 1205 is provided at one end of the inner pipe 121 located inside the outer pipe 122. 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 setting of the auxiliary spring 128 can further improve the reset effect of the sliding block 125 and the separation effect between the plugging plate 127 and the water discharge hole 124.

[0051] In an implementable manner, a number of hollow through holes are provided on the support plate 1205. The connecting rod 126 is slidably arranged in the middle of the support plate 1205. The setting of the hollow through holes on the support plate 1205 is to prevent water from accumulating between the sliding block 125 and the end of the inner pipe 121, resulting in the problem that when the water pressure acts on the sliding block 125, the sliding block 125 cannot squeeze the water and cannot move downward.

[0052] In an implementable manner, a retaining ring 129 is provided on the inner wall of the inner pipe 121 above the sliding block 125. The retaining ring 129 is slidably connected to the inner side surface of the inner pipe 121. A number 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.

[0053] When the sliding block 125 moves downward, it drives the retaining ring 129 to move downward. The downward-moving retaining ring 129 blocks all the water outlet holes 123, so that the water outlet holes 123 cannot drain water, and further reduces the waste of the water flow supplied into the water supply pipe 8. At the same time, it is not difficult to understand that this design also has additional technical effects in this technical solution. When the water pressure gradually increases and decreases, the retaining ring 129 will gradually move downward and gradually move upward, which can change the aperture of the water outlet holes 123 (from large to small and from small to large). When the aperture becomes smaller, the pressure and shooting speed of the water flow ejected can be increased, which can impact the sediment in the drain hole and discharge the adhered sediment, and also has the effect of clearing the hole.

[0054] In an implementable manner, mounting flanges 1204 are provided at the ends of the inner pipe 121 and the outer pipe 122. The mounting flanges 1204 are used to connect to the ends of the infiltration drain pipe 6 and the drain pipe 7, and a filter screen 11 can be provided on the side of the mounting flange 1204 close to the water inlet.

[0055] A construction method for a high-level competition venue structure includes the following steps:

[0056] S1. Lay a layer of sandy soil layer on the construction area of the basement beam-slab structure 1, and lay the surface of the sandy soil layer in a wavy shape;

[0057] S2. Lay a whole waterproof membrane on the surface of the wavy sandy soil layer, and lay the surface of the waterproof membrane flat;

[0058] S3. Lay another layer of sandy soil layer on the surface of the waterproof membrane to completely cover the waterproof membrane;

[0059] S4. Construct the infiltration drain pipe 6, the drain pipe 7 and the water supply pipe 8 on the sandy soil layer on the surface of the waterproof membrane;

[0060] S5. Lay a layer of gravel layer on the constructed infiltration drain pipe 6, drain pipe 7 and water supply pipe 8;

[0061] S6. Construct a layer of geotextile layer on the gravel layer to completely cover the gravel layer;

[0062] S7. Lay a layer of fiber sand surface layer 5 flat above the geotextile layer.

[0063] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
