[0002] In the prior art, the permeable plastic playground is made of permeable materials from the surface layer to the base layer. However, this permeable plastic playground must not only ensure the good permeability of the venue, but also require the venue to have stable bearing capacity. In order to achieve the permeability of the venue, the venue needs to have good permeability from the surface layer to the base layer.

DETAILED DESCRIPTION
[0029] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. The utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
[0030] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.
[0031] See also Figures 1 to 5 The utility model provides a drainage system for a permeable plastic field 100 . The permeable plastic field 100 is usually arranged adjacent to a green space 200 , so that the permeable plastic field 100 has an edge 300 adjacent to the green space 200 .
[0032] For further information, see Figure 2 The drainage system of the permeable plastic field 100 includes a surface layer 20, a leveling layer 30, a base layer 10 and a drainage device 11. The surface layer 20 is made of a permeable plastic material, and the leveling layer 30 is arranged on the lower side of the surface layer 20 to play a role in finding the drainage slope. The base layer 10 is arranged on the lower side of the leveling layer 30, and its permeability is lower than that of the surface layer 20 and the leveling layer 30, and its rigidity is greater than that of the surface layer 20 and the leveling layer 30, thereby providing a stable support for the surface layer 20 and the leveling layer 30 of the upper layer, ensuring the bearing capacity and stability of the site. Generally speaking, the material of the leveling layer 30 is cement mortar, which has a certain permeability and is convenient for leveling and / or slope construction. And / or, the base layer 10 is a cast-in-place reinforced concrete slab, and preferably, a steel mesh is arranged in the base layer 10. In this way, the drainage device 11 and the steel mesh can be arranged first, and then concrete is poured on site, so that the base layer 10 is formed and the drainage device 11 is effectively fixed. At the same time, the steel mesh provides good crack resistance for the base layer 10 , thereby increasing the durability and reliability of the base layer 10 .
[0033] The drainage device 11 includes a floor drain 111 and a drainage pipe 112 pre-buried in the base 10. The water inlet end of the floor drain 111 is arranged on the upper surface of the base 10, and the water outlet end is connected to the drainage pipe 112 buried in the base 10. The drainage pipe 112 is used to connect to the rainwater pipe. Generally speaking, the water outlet end of the drainage pipe 112 can be connected to the municipal rainwater pipe. There are multiple floor drains 111 distributed at intervals on the upper surface of the base 10, so that multiple floor drains 111 drain water at the same time, improve drainage efficiency, and reduce the probability of water accumulation on the upper side of the base 10. Through this design, the utility model not only ensures the permeability of the site, but also improves the bearing capacity and stability of the site, avoiding the problem of insufficient stability and bearing capacity due to the inability to balance the permeability and strength of the base 10. At the same time, the design of the drainage device 11 buried in the stable base 10 effectively prevents the problem of damage to the drainage pipe due to deformation of the base 10, ensuring the long-term effectiveness of the drainage system.
[0034] The layout of the multiple floor drains 111 can be selected as needed. In this embodiment, the multiple floor drains 111 are laid out in a square array on the upper surface of the base 10, and the center distance between each two adjacent floor drains 111 is less than or equal to 5m. Through this design, the distribution of the floor drains 111 is more uniform, and the average drainage area of each floor drain 111 is approximately 25 square meters, so that rainwater on the site can be quickly drained to prevent the occurrence of water accumulation, further improving the drainage effect and service life of the permeable plastic site 100.
[0035] Based on the previous embodiment, please refer to Figures 3 to 5 Preferably, the drainage pipeline 112 includes a plurality of first drainage pipes 1121 extending in the horizontal direction and a plurality of second drainage pipes 1122 extending in the vertical direction. The first drainage pipes 1121 are arranged in a grid shape in the base layer 10 to form a water drop point at each intersection of two first drainage pipes 1121. A plurality of second drainage pipes 1122 are provided, and each second drainage pipe 1122 is connected to the corresponding first drainage pipe 1121, and extends upward from the water drop point. The upper end of each second drainage pipe 1122 is connected to each floor drain 111 above one by one. Through this design, rainwater discharged from each floor drain 111 can be discharged through the plurality of first drainage pipes 1121, and the drainage speed is faster. At the same time, when the drainage volume is too large, a large amount of rainwater can be stored in the first drainage pipes 1121 arranged in a grid shape, thereby improving the situation that when there is too much rainwater, it overflows from the floor drain 111, resulting in poor drainage of the site.
[0036] For further information, please refer to Figure 3 A crushed stone layer 40 and a pond residue cushion layer 50 are also arranged from top to bottom below the base layer 10. The crushed stone layer 40 is preferably graded crushed stone, which has good water permeability and bearing capacity, and the pond residue cushion layer 50 further improves the drainage performance of the site.
[0037] Based on the above embodiments, please refer to Figure 1 and Figure 2 The permeable plastic playground 100 also has an edge 300 adjacent to the green space 200, and the drainage system of the permeable plastic playground 100 also includes a gutter structure 60 extending along the edge 300. Preferably, a drainage slope toward the gutter structure 60 is set on the upper side of the surface layer 20. In this embodiment, a gutter structure 60 is set between the permeable plastic playground 100 and the green space 200. The gutter structure 60 can effectively collect and drain rainwater on the surface layer 20, thereby increasing the drainage speed, reducing the permeability burden of the surface layer 20 and the leveling layer 30, and can quickly drain water when the rainfall is large, thereby improving the water accumulation of the permeable plastic playground 100.
[0038] Optionally, see Figure 2 and 3 The upper side of the base layer 10 is provided with an open groove 12 extending along the edge 300, the bottom of the open groove 12 is connected to the drainage pipe 112, the side ditch structure 60 includes a drainage board 61, a trim strip 62 and a plurality of rainwater grates 63 arranged in the open groove 12, the cross section of the drainage board 61 is L-shaped, and has a long side 611 arranged above the base layer 10 and spaced from the base layer 10, and a short side 612 extending upward from one side of the long side 611, and the plurality of rainwater grates 63 are provided. The rainwater grates 63 are arranged at intervals along the edge 300 on the long side 611, and the short side 612 is arranged close to the green space 200. The edge strip 62 is close to the other side of the long side 611 opposite to the short side 612, and is extended along the edge 300. The edge strip 62 extends upward from the base layer 10, and the top is flush with the upper side of the surface layer 20. The edge strip 62 and the drainage board 61 together enclose a drainage ditch with an open upper side and extending along the edge 300. The edge strip 62 protects the edge of the surface layer 20 and the leveling layer 30 to prevent rainwater from seeping back. The rainwater collected in the drainage ditch flows into the bottom of the open groove 12 of the lower layer through the rainwater grates 63, and then flows into the drainage pipe 112. Through this design, the ditch structure 60 can effectively collect and drain rainwater.
[0039] Preferably, the rainwater grate 63 is made of a finished composite resin material, so that it has good corrosion resistance and durability, can effectively drain rainwater for a long time, and improves the reliability and service life of the ditch structure 60.
[0040] Preferably, the material of the drainage board 61 is granite; and / or the material of the edge strip 62 is stainless steel. It has good water-proof performance and good durability and beautiful visual effect.
[0041] Obviously, the above described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, ordinary technicians in this field can make other different forms of changes or modifications without creative work, which should fall within the scope of protection of the utility model.
