DETAILED DESCRIPTION

[0023] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by "up", "down", "left", "right", "inside", "outside", "top" and "bottom" are all based on the directions or positional relationships shown in the accompanying drawings. The purpose is only to facilitate the description of the present invention and simplify the description. It does not indicate or imply that the referred parts must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0025] Depend on Figures 1 to 8As shown, a multifunctional trail brick system with rapid infiltration and drainage includes a trail brick 1, and the trail brick 1 includes a body 11. The trail brick body 11 can be of two specifications: 400mm*400mm and 400mm*800mm. The thickness of the body is 250mm-300mm, and the body material should be non-slip, strong and wear-resistant. The body 11 is provided with a plurality of vertical drainage holes 13, and the drainage holes 13 are connected from top to bottom. Preferably, the drainage holes 13 are tapered holes with an upper diameter smaller than a lower diameter. The upper diameter can be Φ5mm, and the lower diameter can be Φ30mm. This can not only speed up the water infiltration speed, but also prevent the water at the bottom of the trail brick from splashing upward. There can be 4 drainage holes 13, which are evenly distributed along the plane of the body 11. The upper surface of the body 11 can be provided with a small water trough pattern, and the drainage holes 13 are arranged at the intersection of the water trough, which can play a role in water repellency. A vertical hoisting hole 12 is provided at the center of the main body 11. The hoisting hole 12 is a straight hole, which also penetrates from top to bottom. The diameter of the hoisting hole 12 can be Φ16mm. Semicircular threading grooves 15 are provided on the four side walls of the main body 11. After the walkway bricks are paved, a circular threading hole is formed between two adjacent walkway bricks, which can be used to pass through various lighting and monitoring cables, and to lay the wires reasonably to any position at will. The threading groove 15 divides the main body 11 into an upper main body and a lower main body. In order to ensure the strength of the walkway bricks, the diameter of the threading groove 15 is not greater than half of the thickness of the main body 11, and the thickness of the upper main body is greater than the thickness of the lower main body. When the thickness of the main body is 250mm, the diameter of the threading groove 15 can be set to 100mm, the thickness of the upper main body is 100mm, and the thickness of the lower main body is 50mm. The four side walls of the main body 11 are each provided with a fulcrum 14, and the fulcrum 14 is located on the upper side wall of the main body below the threading groove 15. Four fulcrums 14 are provided on each side, and the fulcrum positions of each surface are the same. In this way, when paving, it can be ensured that the fulcrums 14 of two adjacent walkway bricks are in contact, so that there is a gap between the two bricks, which helps the water on the surface to flow down.

[0026] When paving the walkway brick, a rubber pad 5 is used in conjunction with the rubber pad 5, the lower part of which is a cross and the top of the cross is a nail cap. When the walkway brick 1 is laid, the cross at the lower part of the rubber pad 5 is located between four adjacent bricks, and the nail cap is located on the surface of the four bricks, thereby supporting the four adjacent bricks to avoid collision.

[0027] The walkway brick system also includes a curbstone 2, which is L-shaped. A curbstone wire groove 21 with a semicircular cross section is opened on the inner side wall of the L-shaped vertical edge. When paving, the walkway brick 1 is located above the bottom edge of the L-shape, so that the threading groove 15 is opposite to the curbstone wire groove 21 in height, forming a cable duct with a circular cross section. A plurality of curbstone drainage holes 23 are opened between the outer side wall of the L-shaped vertical edge and the L-shaped bottom edge, and the curbstone wire groove 21 is connected to each curbstone drainage hole 23 through a wire groove drainage hole 22. In this way, the accumulated water on the road surface outside the curbstone 2 can be discharged to the bottom of the road surface through the curbstone drainage hole 23, and the accumulated water on the walkway brick 1 can be discharged to the curbstone drainage hole 23 through the cable duct and the wire groove drainage hole 22, and then discharged to the bottom of the road surface.

[0028] Preferably, the walkway brick system may further include a drainage ditch 3, the cross section of which is U-shaped and can be prefabricated in advance, and supports 31 are provided at both ends of the drainage ditch 3 to support the U shape to keep it stable. During paving, the opening of the U-shaped groove is located at the bottom of the roadside stone drainage hole 23, so that water on the road surface can be discharged into the drainage ditch 3.

[0029] When laying the walkway brick system, if the cable needs to pass through the road surface, the cable can pass through the threading groove 15 formed by the adjacent walkway bricks 1. When the cable needs to turn or change direction, a cable well 4 can be set at the turning point. The cable well 4 is a square frame structure, and its area occupies two walkway bricks 1. The cable well 4 can be placed after removing two walkway bricks at the turning point. A number of cable well threading holes 41 are opened on the side wall of the cable well 4 frame. The cable well threading holes 41 correspond to the positions of the threading groove 15 on the walkway bricks 1. A well cover is provided on the upper part of the cable well 4, and a mark is provided on the well cover. When the cable passes through the cable well 4, it passes through any cable well threading hole 41 on the cable well 4 according to the direction of the turn, so that the cable changes direction while avoiding cable bending.

[0030] The walkway brick system can be laid on the existing road surface with walkway bricks 1 alone to strengthen the drainage of the road surface, or it can be laid together with curbstones 2, drainage ditches 3, and cable wells 4 to achieve better drainage effect. When paving, the walkway brick system does not require a concrete cushion layer. It uses river sand with a thickness of not less than 250mm. After being compacted by water sinking, measuring the height and scraping it flat, it can be directly placed evenly to save costs. Since the walkway bricks 1 have drainage holes 13, drainage ditches 3 can be set under the road surface during paving, and connected to the rainwater collection system through a water pipeline. At the same time, curbstone drainage holes 23 are set at the curbstones 2 near the roadside, so that the water on the road surface can more conveniently enter the drainage ditch 3. The walkway brick has good stability and large bearing capacity. After the ground construction foundation is handled well, it is no problem to carry a small car. In addition, due to good drainage, it is not easy to produce the phenomenon of bulging after freezing in winter, making the road surface more durable. Since a complete threading hole is formed on the adjacent sides of the two bricks, various lighting and monitoring cables can be passed through. The introduction points are reasonably arranged, and any point can be reached at will. When laying pipelines, the bricks can be removed through the lifting holes on the bricks, and then the wire threading construction can be carried out without large-scale destruction and re-laying, which not only reduces the construction difficulty, but also saves the construction volume of secondary laying and the loss of bricks, saving costs and reducing resource waste. When high-voltage cables need to pass under the road surface, the high-voltage cable protection groove can be buried under the bricks in advance, thereby saving the overall paving time. Since this brick system adopts an assembly process without any bonding, it is more convenient to construct. If there is a collapse and it is necessary to work below, there will be no loss of materials, and the construction is convenient.
