DETAILED DESCRIPTION
[0020] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0021] like Figures 1 to 3 As shown, the utility model provides a roof sports field runway structure, including a runway, a concrete layer 1, a structural cover plate 2, a support member 3, a drainage layer 4, a support pad 5, a waterproof layer 6, a blind ditch 7 and a deformation joint assembly 8. The runway is arranged above the concrete layer 1 to provide a required load-bearing platform for the runway through the concrete layer 1. The structural cover plate 2 is arranged below the concrete layer 1 to protect the lower structure and prevent roof water from penetrating into the deformation joint assembly 8. The support member 3, the drainage layer 4 and the deformation joint assembly 8 are arranged below the concrete layer 1. The support member 3 includes a first support portion 31, a second support portion 32 and a base 33. The first support portion 31 and the second support portion 32 are arranged relative to each other. It is placed on both sides of the base 33, and a blind ditch 7 is formed between the first support part 31 and the second support part 32 to accelerate the removal of accumulated water and reduce the risk of leakage; the first support part 31 is connected to the edge of the structural cover plate 2 to support the structural cover plate 2 to ensure the stability of the structure; the second support part 32 is connected to the structural cover plate 2 through a support pad 5 to adapt to structural deformation and reduce stress concentration; drainage layers 4 are provided on both sides of the blind ditch 7 to collect and guide seepage water to drain the seepage water to the blind ditch 7 to prevent accumulated water from damaging the structure, and a waterproof layer 6 is provided on the side of the deformation joint assembly 8 facing the concrete layer 1, and is connected to the base 33 and the drainage layer 4 through the waterproof layer 6 to prevent moisture penetration.
[0022] Based on the above structure, this embodiment solves the leakage problem of the roof sports field caused by the deformation joint through a multi-layer waterproof and drainage structure. At the same time, the combination of the support member 3 and the drainage layer 4 solves the problem of water accumulation, while the waterproof layer 6 and the deformation joint assembly 8 ensure that a good sealing state can be maintained even when the structure is deformed, thereby protecting the lower structure from water damage.
[0023] It should be noted that the deformation joint assembly 8 of this embodiment is subjected to a plate lowering treatment, preferably by 1 meter, to reduce the impact of telescopic vibration on the runway and ensure the flatness of the runway surface.
[0024] The concrete layer 1 in this embodiment includes a 30 mm thick fine-grained stone asphalt concrete layer, a 50 mm thick medium-grained stone asphalt concrete layer and a 120 mm thick C25 plain concrete structure layer, which are laid in sequence from bottom to top, and are finally compacted by stone powder and 6% cement. It should be noted that the crushed stone particle size of the 30 mm thick fine-grained stone asphalt concrete layer is ≤10, and the crushed stone particle size of the 50 mm thick medium-grained stone asphalt concrete layer is ≤20.
[0025] In some embodiments, a guide pipe 34 is buried in the first support portion 31 and the second support portion 32 to guide the seepage water to the blind ditch 7, thereby reducing the time that the structure is immersed in the accumulated water and preventing water damage; the drainage layer 4 has a first drainage slope 41, and the first drainage slope 41 is inclined downward in the direction close to the blind ditch 7 to guide the water flow to move in a specified direction. The slope of the first drainage slope 41 is 5% to ensure that the water can flow smoothly without stagnation.
[0026] In some embodiments, the blind ditch 7 has a second drainage slope, forming a drainage path from top to bottom with a gentle slope, and the second drainage slope in the blind ditch 7 is more gentle, with a slope of 1%, which is used to ensure that the water flow in the blind ditch 7 flows stably and continuously toward the drainage outlet, avoiding water accumulation, reducing the risk of infiltration caused by increased hydrostatic pressure, and avoiding erosion or scouring of local areas due to excessively fast water flow.
[0027] In some embodiments, the connection between the first support part 31 and the structural cover plate 2 is filled with a sealing compound 35 to seal the small gap between the two parts and prevent water from seeping from the roof from penetrating into the structure through these gaps. In addition, by filling the sealing compound 35, the integrity of the connection between the first support part 31 and the structural cover plate 2 can be enhanced, and the gap expansion that may be caused by slight displacement caused by vibration or temperature difference can be reduced, thereby improving the stability and durability of the entire structure.
[0028] In some embodiments, the waterproof layer 6 is connected to the structural cover plate 2 through the support pad 5, which can effectively isolate the upper and lower layers, prevent the structural cover plate 2 from directly pressing the waterproof layer 6, reduce the damage or rupture of the waterproof layer 6 caused by excessive pressure, and thus protect the lower waterproof layer 6 from physical damage. In addition, the support pad 5 allows a certain displacement space between the waterproof layer 6 and the structural cover plate 2 to adapt to these tiny deformations, maintain the continuity and sealing of the waterproof layer 6, prevent cracking and leakage, and facilitate air circulation and water evaporation, reduce moisture inside the structure, resist mold growth, and further enhance the waterproof effect.
[0029] It should be noted that the support pad 5 in this embodiment is an M5 cement mortar pad, and the structural cover plate 2 is divided into multiple areas, each area is 50*50mm, and 4-6 support pads 5 are arranged in each area.
[0030] like Figure 3 As shown, the waterproof layer 6 includes a top lining 61, a waterproof group 62 and a backing 63. The waterproof group 62 is arranged between the top lining 61 and the backing 63. The top lining 61 is used to protect the waterproof group 62. The waterproof group 62 is used to block moisture penetration. The backing 63 is connected to the deformation joint assembly 8 to prevent leakage points from forming around the deformation joint.
[0031] In some embodiments, the waterproof group 62 includes multiple layers of waterproof rolls stacked in sequence. In this embodiment, the overall barrier capacity of the waterproof layer 6 is improved by stacking multiple layers of rolls, effectively preventing water penetration. At the same time, the multi-layer stacking can provide redundant protection. Even if one layer is damaged, the other layers can still continue to function, ensuring the long-term effectiveness of the waterproof system.
[0032] In some embodiments, the expansion joint assembly 8 includes an expansion joint body 81, a seal 82, an insulation layer 83 and a drain pipe 84. The waterproof layer 6 is arranged around the side of the expansion joint body 81 facing the concrete layer 1. The expansion joint body 81 has a drain ditch. The insulation layer 83 is arranged at one end of the drain ditch facing the waterproof layer 6 to reduce heat transfer and prevent the adverse effects of thermal expansion and contraction caused by temperature difference on the structure. It can also serve as a transition between the waterproof layer 6 and the drain ditch to protect the waterproof layer 6 from extreme temperatures. A seal 82 is arranged on the side of the insulation layer 83 facing the waterproof layer 6 to fill the gap between the expansion joint body 81 and the insulation layer 83 to ensure airtightness and prevent moisture and air penetration. It can also adapt to slight movements of the structure and maintain a good sealing effect. The drain pipe 84 is connected to the end of the drain ditch away from the waterproof layer 6 to drain the collected rainwater or accumulated water inside the structure to prevent the accumulated water from damaging the building foundation or structure and keep the structure dry and stable.
[0033] In some embodiments, the drainage ditch has a third drainage slope, which extends downward and is inclined toward the axis of the drainage ditch, ensuring that the water flow can be discharged smoothly toward the downstream of the ditch to promote the accumulated water in the ditch to flow smoothly along the ditch. The slope of the third drainage slope is 5%, ensuring that the water flow will not cause erosion due to excessive flow rate, nor will the water flow be too slow to cause sediment accumulation.
[0034] In some embodiments, a fireproof belt 85 is provided on the side of the drainage ditch close to the drain pipe 84, and the fireproof belt 85 is located on the side of the insulation layer 83 away from the waterproof layer 6, so as to effectively prevent the fire from spreading further to a wider area through the drainage ditch.
[0035] In summary, the embodiment of the utility model provides a rooftop sports field runway structure, which solves the leakage problem caused by deformation joints in the rooftop sports field through a multi-layer waterproof and drainage structure. At the same time, the combination of the support member 3 and the drainage layer 4 solves the problem of water accumulation, while the waterproof layer 6 and the deformation joint assembly 8 ensure that a good sealing state can be maintained even when the structure is deformed, thereby protecting the lower structure from water damage.
[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
