Description

Technical Field

[0001] The utility model relates to the technical field of three-dimensional vegetation nets, in particular to a three-dimensional vegetation net structure for slope protection. Background Art

[0002] Three-dimensional vegetation net slope protection refers to the use of active plants combined with engineering materials such as geosynthetics to build a protection system with self-growth ability on the slope surface. It is a new technology to reinforce the slope through the growth of plants. The three-dimensional vegetation net slope protection technology combines the advantages of geonet and plant slope protection, and can effectively solve the protection problems of rock slopes and high and steep slopes.

[0003] The three-dimensional vegetation net is also called three-dimensional net, plastic three-dimensional net, etc. It is generally composed of flat net, stretched net, foamed net. If there are special tensile requirements, a layer of fiberglass grid can be added to increase the tensile force. It is degradable and will not pollute the environment. It is a three-dimensional structured loofah network-like net mat used for planting grass and consolidating soil in the three-dimensional vegetation net slope protection. Its main function is to resist erosion and promote the germination of grass seeds to form a green composite protective layer.

[0004] During construction, the three-dimensional vegetation net is generally laid on the slope from top to bottom, with two adjacent three-dimensional vegetation nets overlapping and then fixed at the overlapping parts by U-shaped nails. Finally, improved soil is backfilled or hydraulic seeding is carried out on the upper part of the three-dimensional vegetation net. Due to the slope, the three-dimensional vegetation net has a tendency to slide down when backfilling improved soil and hydraulic seeding is carried out, resulting in a large tensile force on the upper three-dimensional vegetation net. In the later use process, it is easy to slide down due to the gravity of the filler, the sliding force and the erosion of wind and rain. Based on this, a three-dimensional vegetation net structure for slope protection is provided. Utility Model Content

[0027] 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.

[0028] See also Figures 1 to 3 In an embodiment of the utility model, a three-dimensional vegetation net structure for slope protection includes a three-dimensional vegetation net 1, and a pressing component 2 is pressed on the upper surface of the three-dimensional vegetation net 1. The pressing component 2 is used to fix the three-dimensional vegetation net 1 to the slope surface and fix the overlap of two three-dimensional vegetation nets 1 at the same time;

[0029] The pressing assembly 2 includes a fixing unit and a reinforcement unit. The fixing unit is used to fix the three-dimensional vegetation net 1 to the slope surface and to fix two three-dimensional vegetation nets 1 to each other. The reinforcement unit is used to increase the fixed connection force between the three-dimensional vegetation net 1 and the slope surface.

[0030] The fixing unit includes an inclined pressing plate 201, a through hole 202, and a U-shaped nail 203;

[0031] A plurality of inclined pressing plates 201 are arranged in sequence in a "W" shape along the longitudinal direction of the paving of the three-dimensional vegetation net 1, and the joint of two adjacent inclined pressing plates 201 is aligned with the center line of the three-dimensional vegetation net 1, and a single inclined pressing plate 201 contacts two three-dimensional vegetation nets 1 at the same time;

[0032] The through holes 202 are grouped in pairs and are evenly distributed along the long side direction of the inclined pressing plate 201;

[0033] The U-shaped nails 203 penetrate a group of through holes 202 from above the inclined pressure plate 201 and penetrate the three-dimensional vegetation net 1 and are inserted into the soil on the slope to fix the three-dimensional vegetation net 1 to the slope. The insertion of multiple U-shaped nails 203 can fix two three-dimensional vegetation nets 1.

[0034] In this embodiment, when paving the three-dimensional vegetation net 1, the three-dimensional vegetation net 1 is laid on the slope from top to bottom in sequence, and two adjacent three-dimensional vegetation nets 1 are overlapped, and then the three-dimensional vegetation net 1 is fixed by using the clamping component 2, and the operation steps are as follows:

[0035] First, an inclined pressing plate 201 is taken out and pressed on the overlapping area of ​​the two three-dimensional vegetation nets 1, and the two ends of the inclined pressing plate 201 are respectively located at the midline of the two three-dimensional vegetation nets 1 (it should be noted that: the midline position does not need to be too precise, it only needs to be roughly aligned), and then the U-shaped nail 203 is hammered by an external tool (for example: a hammer) to make it penetrate the through hole 202, the three-dimensional vegetation net 1 and the inside of the slope soil. The insertion of multiple U-shaped nails 203 can realize the fixation of the three-dimensional vegetation net 1 and the slope, and at the same time realize the mutual fixation of the two three-dimensional vegetation nets 1;

[0036] Then take out the second inclined pressure plate 201 and make it in the opposite state with the first inclined pressure plate 201, and then splice the second inclined pressure plate 201 to one side of the first inclined pressure plate 201. This inclined pressure plate 201 will be pressed between the second three-dimensional vegetation net 1 and the third three-dimensional vegetation net 1, and then fixed with U-shaped nails 203. In this way, the three-dimensional vegetation net 1 can be completely fixed.

[0037] Please refer to Figures 1 to 3 , the reinforcement unit includes a middle-shaped slide groove 204 and a double cone head 205;

[0038] The Chinese character chute 204 is opened inside the inclined pressure plate 201 and passes through the upper and lower ends of the U-shaped nail 203. The double cone head 205 vertical slide is connected to the inner side of the Chinese character chute 204 and protrudes from the upper and lower ends of the inclined pressure plate 201. The double cone head 205 passes through the three-dimensional vegetation net 1 and is inserted into the soil on the slope to increase the fixed connection force between the three-dimensional vegetation net 1 and the slope.

[0039] The reinforcement unit also includes a limiting ring 206;

[0040] The limiting ring 206 is fixed to the outer side of the middle part of the double cone head 205 and is slidably connected to the inner notch of the middle part of the middle-shaped slide groove 204. The limiting sliding of the limiting ring 206 and the middle-shaped slide groove 204 is used to provide telescopic movement guidance and limitation for the double cone head 205;

[0041] Through the two symmetrical cone head structures of the double cone head 205 and the moving function of the double cone head 205, both the front and back sides of the inclined pressing plate 201 can be used normally, so as to realize that multiple inclined pressing plates 201 are overlapped in a "W" shape;

[0042] The Chinese-shaped chute 204, the double cone head 205, and the limit ring 206 are symmetrically arranged in two groups with the distribution track of the through hole 202 as the center line. The two groups of Chinese-shaped chute 204, the double cone head 205, and the limit ring 206 include a plurality of Chinese-shaped chute 204, the double cone head 205, and the limit ring 206 uniformly distributed along the long side track of the inclined pressure plate 201;

[0043] A plurality of pressing components 2 are arranged along the slope inclination direction, so as to separate the three-dimensional vegetation net 1 into a plurality of separate stress-bearing areas along the slope inclination direction.

[0044] In this embodiment: after the inclined pressure plate 201 is fixed by the U-shaped nail 203, the top of the double cone head 205 protruding from the inclined pressure plate 201 can be hammered by an external tool (for example, a hammer) to move the double cone head 205 downward, and the bottom of the double cone head 205 passes through the three-dimensional vegetation net 1 and is inserted into the slope soil (it should be noted that the depth of the double cone head 205 inserted into the soil is shallower than that of the U-shaped nail 203), and the top of the double cone head 205 is stored inside the inclined pressure plate 201. After hammering multiple double cone heads 205, the connection force between the double cone head 205 and the slope can be effectively increased, and the three-dimensional vegetation net 1 can be divided into multiple areas by multiple groups of crimping components 2. Different from the traditional structure that is fixed only by U-shaped nails at the overlap, the forces in multiple areas of the three-dimensional vegetation net 1 are independent of each other, avoiding the situation where the three-dimensional vegetation net 1 close to the top of the slope is subjected to excessive tension and affects the stability of subsequent use, thereby effectively improving the paving stability of the three-dimensional vegetation net 1.
