Abstract

The utility model relates to the technical field of composite geomembrane processing, in particular to a multi-dimensional hole structure of a composite geomembrane, which comprises a composite geomembrane body, reinforcing layers and fixing holes. A fixing hole is formed in the reinforcing layer; the side surface of the fixing hole is connected with a buffer layer; when water impacts the composite geomembrane body, the composite geomembrane body deforms, at the moment, the fixing holes stretch, so that impact energy of the water is converted into compression energy of the fixing springs, the buffer layer moves along with stretching of the fixing holes, and the buffer layer restores to the original position when the water flow impacts the buffer layer. And therefore, the impact force is weakened by using the spring and the buffer layer, and the composite geomembrane body is prevented from being damaged.

Description

Technical Field

[0001] The utility model relates to the technical field of composite geomembrane processing, in particular to a composite geomembrane multi-dimensional pore structure. Background Art

[0002] Composite geomembranes are widely used in channel anti-seepage projects. In recent years, the extensive application and effectiveness of geosynthetics in civil engineering, especially in flood control and rescue projects, have attracted great attention from engineering and technical personnel. However, when general composite geomembranes are used, when they are subjected to large impact forces, the composite geomembranes are prone to tearing after deformation due to the lack of multi-dimensional pore structures on their surfaces, which is not conducive to the continuous use of composite geomembranes. Summary of the invention

[0003] The utility model aims to provide a composite geomembrane with a multi-dimensional pore structure to solve the problems raised in the above-mentioned background technology.

[0004] A composite geomembrane multi-dimensional pore structure comprises a composite geomembrane body, a reinforcement layer and fixing holes: a circular reinforcement layer is arranged at the corners and the center of the composite geomembrane body, a fixing hole is arranged inside the reinforcement layer, and a buffer layer is connected to the side of the fixing hole.

[0005] When the device is in use, the composite geomembrane body is fixed at the corners of the composite geomembrane body, so that the composite geomembrane body can be used. During use, the fixing holes at different positions of the composite geomembrane body form a multi-dimensional hole structure, thereby protecting the composite geomembrane body.

[0006] Preferably, the fixing hole is vertical.

[0007] When the device is in use, since the fixing holes are vertical, when water impacts the composite geomembrane body, the fixing holes will open, thereby giving the composite geomembrane body a larger deformation space, thereby preventing the composite geomembrane body from being damaged by water impact.

[0008] Preferably, the buffer layer is arc-shaped and has elasticity.

[0009] When the composite geomembrane body is impacted, the fixed holes will open, allowing water to enter the buffer layer. At this time, the fixed holes will expand, and when the fixed holes expand, the buffer layer will be stretched, thereby reducing the curvature of the buffer layer. When the water flow impacts the buffer layer, the curvature of the buffer layer will increase, causing the composite geomembrane body and the fixed holes to return to their original positions, thereby weakening the impact force.

[0010] Preferably, a fixing bolt is embedded in the reinforcement layer at the center of the side of the fixing hole, the embedded end of the fixing bolt is in a straight line shape, the other end of the fixing bolt is conical, and reinforcing rods are equidistantly arranged outside the conical end of the fixing bolt.

[0011] When the device is in use, the fixing bolt is embedded in the reinforcing layer, and the reinforcing rod can prevent the fixing bolt from moving outward, and the fixing bolt and the reinforcing layer are connected and fixed by an adhesive.

[0012] Preferably, a connecting rod is connected to the side of the fixing bolt, a fixing head is slidably provided inside the connecting rod, a supporting rod is connected to the outside of the fixing head, a fixing spring is provided on the outside of the supporting rod, and the fixing spring is provided inside the connecting rod.

[0013] When the device is in use, the fixing bolt will move with the fixing hole. When the fixing bolt moves outward, the connecting rod will also move with it. At this time, the fixing head will slide inside the connecting rod, and the fixing spring will be squeezed and contracted, thereby converting the impact force on the composite geomembrane body into compression energy of the fixing spring, making it easier for the device to return to its original position, and at the same time using the fixing spring to restore the connecting rod to its original position.

[0014] The beneficial effects of the utility model are:

[0015] 1. When water impacts the composite geomembrane body, the composite geomembrane body will be deformed. At this time, the fixed holes will open, thereby converting the impact energy of the water into the compression energy of the fixed spring, and the buffer layer will also move with the opening of the fixed holes. When the water flow impacts the buffer layer, it will return to its original position, thereby using the spring and buffer layer to weaken the impact force and avoid damage to the composite geomembrane body.

[0021] 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.

[0022] When implementing: Figure 1-3 As shown, a composite geomembrane multi-dimensional pore structure includes a composite geomembrane body 1, a reinforcement layer 2 and fixing holes 3: a circular reinforcement layer 2 is arranged at the corners and center of the composite geomembrane body 1, and a fixing hole 3 is arranged inside the reinforcement layer 2, and a buffer layer 10 is connected to the side of the fixing hole 3.

[0023] When the device is in use, the composite geomembrane body 1 is fixed at the corners of the composite geomembrane body 1, so that the composite geomembrane body 1 is used. During use, the fixing holes 3 at different positions of the composite geomembrane body 1 form a multi-dimensional hole structure, thereby protecting the composite geomembrane body 1.

[0024] The fixing hole 3 is vertical.

[0025] When the device is in use, since the fixing holes 3 are vertical, when water impacts the composite geomembrane body 1, the fixing holes 3 will open, thereby giving the composite geomembrane body 1 a larger deformation space, thereby preventing the composite geomembrane body 1 from being damaged by the impact of water flow.

[0026] The buffer layer 10 is arc-shaped and has elasticity.

[0027] When the composite geomembrane body 1 is impacted, the fixing holes 3 will open, allowing water to enter the buffer layer 10. At this time, the fixing holes 3 will expand, and when the fixing holes 3 expand, the buffer layer 10 will be stretched, thereby reducing the curvature of the buffer layer 10. When the water flow impacts the buffer layer 10, the curvature of the buffer layer 10 will increase, thereby causing the composite geomembrane body 1 and the fixing holes 3 to return to their original positions, thereby weakening the impact force.

[0028] A fixing bolt 5 is embedded in the center of the side of the fixing hole 3 inside the reinforcement layer 2. The embedded end of the fixing bolt 5 is in a straight line shape, and the other end of the fixing bolt 5 is conical. Reinforcing rods 6 are equidistantly arranged outside the conical end of the fixing bolt 5.

[0029] When the device is in use, the fixing bolt 5 is embedded in the reinforcing layer 2, and the reinforcing rod 6 can prevent the fixing bolt 5 from moving outward, and the fixing bolt 5 and the reinforcing layer 2 are connected and fixed by an adhesive.

[0030] The side of the fixing bolt 5 is connected to a connecting rod 4 , a fixing head 7 is slidably provided inside the connecting rod 4 , the outer side of the fixing head 7 is connected to a supporting rod 8 , a fixing spring 9 is provided outside the supporting rod 8 , and the fixing spring 9 is provided inside the connecting rod 4 .

[0031] When the device is in use, the fixing bolt 5 will move with the fixing hole 3. When the fixing bolt 5 moves outward, the connecting rod 4 will also move with it. At this time, the fixing head 7 will slide inside the connecting rod 4, and the fixing spring 9 will be squeezed and contracted, thereby converting the impact force on the composite geomembrane body 1 into compression energy of the fixing spring 9, which is convenient for the device to return to its original position, and at the same time, the fixing spring 9 is used to restore the connecting rod 4 to its original position.
