Description

Technical Field

[0001] The utility model relates to the technical field of pressure relief drainage boards, in particular to a pressure relief drainage board. Background Art

[0002] Pressure relief drainage board, also known as capillary drainage board, is made of HDPE high-density polymer material with good toughness. It can play a role in binding the soil when buried in the soil. The pressure relief drainage board adopts dense grooves, with a design of large inside and small outside. When buried, the groove faces downward, so that water flows from bottom to top and is sucked back into the capillary water pipe. In this way, soil particles naturally settle due to gravity and will not flow into the capillary water pipe with the water. At the same time, it will not cause siltation near the water inlet groove. However, the downward groove can both let in water and also cause In the aftermath of water leakage, the pressure relief and drainage board uses surface tension to create a sealing effect on the water in the groove to prevent it from leaking back. When water enters, the capillary phenomenon will naturally suck the water in the soil until it is full and discharge it outward by gravity. When the water reaches the outlet, it will produce a siphon effect due to the drop in height, further generating negative pressure inside the soil, greatly improving the drainage efficiency. The pressure relief and waterproof board is also used for tunnel drainage, diverting the tiny water droplets above the tunnel and the flowing water through the drainage trough to the drainage ditches on both sides.

[0003] During the installation of existing pressure relief drainage boards, due to factors such as overlying pressure and horizontal tension, there are problems such as insufficient pressure resistance, flattening of the capillary pore structure, and blockage of the capillary drainage board. Based on this, a pressure relief drainage board is provided. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figures 1 to 3In an embodiment of the present invention, a pressure relief drainage board includes a drainage board 1 consisting of a base plate 101 and a drainage groove 102. The drainage groove 102 is formed at the bottom of the base plate 101. A strip-shaped card groove 103 is opened on the top of the base plate 101. An anti-slip protrusion 104 is formed at the bottom of the base plate 101. The anti-slip protrusion 104 is staggered with the drainage groove 102. The strip-shaped card groove 103 is provided with a reinforcement component 2. The reinforcement component 2 is used to increase the compressive and tensile strength of the base plate 101.

[0019] The reinforcing component 2 includes a reinforcing rib 201, which is clamped to the inner side of the strip-shaped slot 103, and forms a reinforcing rib effect on the interior of the substrate 101 through the reinforcing rib 201;

[0020] A plurality of drainage grooves 102 and strip-shaped card slots 103 are provided along the transverse direction of the substrate 101, and the drainage grooves 102 and strip-shaped card slots 103 are staggered in the horizontal direction;

[0021] A plurality of anti-slip protrusions 104 are evenly arranged along the horizontal longitudinal direction of the substrate 101 .

[0022] In this embodiment, it should be noted that the material strength of the reinforcing component 2 is greater than that of the drain board 1. After the reinforcing component 2 and the drain board 1 are respectively produced and formed, the reinforcing component 2 and the drain board 1 are assembled and hot-melt-welded, and finally the reinforcing rib 201 is completely inserted into the inner side of the strip groove 103.

[0023] When the drainage board 1 is laid later, when the drainage board 1 is subjected to the upper extrusion force, the part of the anti-slip protrusion 104 protruding from the bottom of the base plate 101 will be inserted into the soil, thereby increasing the connection force between the base plate 101 and the ground, so that the base plate 101 will not shift. At the same time, through a number of reinforcing ribs 201 filled on the top of the base plate 101, the tensile and compressive strength of the base plate 101 can be further enhanced, thereby avoiding the drainage board 1 from being flattened, pulled and deformed due to factors such as overlying pressure and horizontal tension, and ensuring the stable drainage effect of the drainage ditch 102. In addition, the width of the reinforcing rib 201 is about 0.5 mm, and the distance between two adjacent reinforcing ribs 201 is 5 cm, which can also prevent slipping and increase friction.

[0024] Please refer to Figures 1 to 3 , hot melt convex edges 105 are integrally formed on both sides of the inner wall of the strip-shaped slot 103, and side slots 202 are formed on both sides of the outer wall of the reinforcing rib 201. The reinforcing rib 201 is clamped to the hot melt convex edge 105 through the side slots 202 to increase the hot melt connection area between the reinforcing rib 201 and the substrate 101;

[0025] The substrate 101 has two sides integrally formed with welding edges 106 , each of which has a width of 15 cm.

[0026] In this embodiment, the side slots 202 are engaged with the hot-melt convex edge 105 to increase the connection area between the reinforcing rib 201 and the base plate 101, thereby further improving the overall connection strength between the reinforcing rib 201 and the base plate 101, thereby maintaining a stable connection between the reinforcing assembly 2 and the drain board 1.

[0027] It should be further explained that the welding edge 106 is used for the hot-melt connection operation between the two substrates 101 .
