DETAILED DESCRIPTION
[0018] 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.
[0019] See also Figure 1 - Figure 3 The utility model provides a technical solution: a park dry creek drainage structure, including a waterproof layer 1, a water storage tank 2 and a filter plate 5. The waterproof layer 1 is a multi-layer structure. The first layer is paved with a flexible waterproof layer, which can be a coating or a coiled material. The second layer is paved with a rigid waterproof layer. The construction is carried out two days after the first flexible waterproof layer is completed. The basic materials are mainly high-grade fatty acid mortar waterproofing agents. The design of the waterproof layer 1 is very important. It not only protects the structure from being invaded by corrosive media, but also prevents external pressure water from penetrating into the structure. The upper surface of the waterproof layer 1 is a curved surface, and the waterproof layer 1 is The center is sunken inward, and a water storage tank 2 is arranged at the center of the waterproof layer 1. The water storage tank 2 is made of cement material and has waterproof performance. It plays the role of collecting and guiding rainwater. A filter plate 5 is arranged on the top of the water storage tank 2. The filter plate 5 is made of stainless steel material and can intercept larger debris carried in rainwater, ensure the cleanliness of water flow, and avoid clogging of the water storage tank 2. Two sets of guide rails 6 are arranged at the bottom of the filter plate 5. The guide rails 6 are long strip components made of metal materials. The guide rails 6 provide a path for the float 7 to move up and down, so as to maintain long-term stability and corrosion resistance.
[0020] A floating ball 7 is connected in the middle of the two sets of guide rails 6 through a connecting ring 14. The floating ball 7 includes a shell 12, a sealing gasket 13, a connecting ring 14 and a composite foam buoyancy material 16. The shell 12 is a hemispherical stainless steel structure. Two sets of shells 12 are provided, and the two sets of shells 12 can be connected into a sphere by bolts. A sealing gasket 13 is provided on the connecting surface of the shell 12. The sealing gasket 13 is made of rubber material and can ensure that the internal space will not be flooded. Connecting rings 14 are provided on both sides of the shell 12. The connecting ring 14 is a metal ring structure. The hole in the center can pass through the guide rail 6. Four sets of rollers 15 are evenly arranged on the inner wall of the connecting ring 14. The roller 15 is a stainless steel ball embedded in the connecting ring 14, which can reduce the friction of the float 7 on the guide rail 6 and improve the sensitivity and accuracy of movement. The interior of the outer shell 12 is filled with a composite foam buoyancy material 16, which is a lightweight synthetic composite foam buoyancy material. This material further reduces the density. By adding large-diameter high-strength fiber synthetic hollow balls and a combination of hollow glass microspheres and epoxy resin to the composite foam material, a so-called three-phase composite foam material is formed, which allows the outer shell 12 to generate huge buoyancy in the water while maintaining sufficient mechanical strength and pressure resistance.
[0021] A No. 1 drainage pipe 4 is arranged on both sides of the water storage tank 2. The No. 1 drainage pipe 4 is a pipe body made of plastic material, buried in the compacted layer 3 below the waterproof layer 1, and laid along the horizontal direction of the compacted layer 3, so that the water in the water storage tank 2 can be drained and irrigated to the plant soil on both sides, ensuring the water demand of the landscape plants and realizing the effective use of rainwater. A No. 2 drainage pipe 8 is arranged at the bottom center of the water storage tank 2. The height of the No. 2 drainage pipe 8 is higher than the bottom half of the height of the water storage tank 2, so that the water storage tank 2 can store rainwater during daily time. When the rainfall surges in the rainy season, the excess rainwater can be discharged through the combination of the float and the No. 2 drainage pipe 8. The water storage tank 2 prevents a large amount of water accumulation while ensuring that rainwater is retained in the water storage tank 2. A gravel filter layer 9 is arranged on the top of the filter plate 5. The gravel filter layer 9 is paved with tiny gravel, which can further increase the infiltration capacity of the water flow. Its larger porosity makes it easier for water to pass through while intercepting smaller particulate impurities. A moss layer 10 is laid above the gravel filter layer 9. The moss layer 10 allows moss plants to be planted on the gravel filter layer 9, which not only increases the aesthetics of the dry creek stone landscape, but also utilizes the natural filtering function of plants to help remove nutrients and other chemicals in the water. A stone landscape layer 11 is arranged on the moss layer 10.
[0022] Working principle: When using a park dry creek drainage structure, first compact the land to form a compacted layer 3, bury two groups of No. 1 drainage pipes 4 in the compacted layer 3, drain and irrigate the plant soil on both sides to ensure the water demand of the landscape plants, and set a water storage tank 2 at the center of the compacted layer 3. The water storage tank 2 is located at the center of the waterproof layer 1, and the waterproof layer 1 is set on the compacted layer 3. The curved surface design of the upper surface of the waterproof layer 1 and the water storage tank 2 in the center help to effectively collect and guide rainwater. At the same time, the curved surface design is conducive to the flow and concentration of rainwater. The water storage tank 2 is provided with a guide rail 6, a float 7 and a No. 2 drainage pipe 8. The top of the water storage tank 2 is provided with a filter plate 5, which can intercept larger debris, ensure the cleanliness of the water flow, and avoid clogging of the drainage system. A gravel filter layer 9 is laid above the filter plate 5. In order to further increase the infiltration capacity of water flow, its larger porosity makes it easier for water to pass through, while intercepting smaller particulate impurities. A moss layer 10 is sown on the gravel filter layer 9. The application of moss plants in the dry creek stone landscape not only increases the aesthetics, but also utilizes the natural filtering function of plants to help remove nutrients and other chemicals in the water. Then a stone landscape layer 11 is laid on the moss layer 10. When rainwater falls, it is filtered by the moss layer 10 and the gravel filter layer 9, and then filtered again through the filter plate 5 into the water storage tank 2. When the rainfall increases sharply and the water level in the water storage tank 2 rises, the float 7 on the guide rail 6 will also rise with the water level, thereby opening the top of the No. 2 drain pipe 8, so that the accumulated water in the water storage tank 2 can be discharged into the sewer, preventing the accumulated water from affecting the park environment.
