Description

Technical Field

[0001] The utility model relates to the technical field of slope protection nets, in particular to a slope protection net for water conservancy projects. Background Technique

[0002] The water conservancy slope protection net is a mesh structure material used for slope protection in water conservancy projects. Common ones include gabion nets, geocells, three-dimensional vegetation nets, etc.

[0003] The three-dimensional vegetation net, also known as the three-dimensional net, plastic three-dimensional net, etc., is generally composed of a flat net, a stretched net, and a foamed net. For those with special tensile requirements, a layer of fiberglass grille can be added to increase the tensile force. It is degradable and does not pollute the environment. It is a three-dimensional structure like a loofah network mat used for grass planting and soil fixation in the three-dimensional vegetation net slope protection. Its main functions are to resist scouring, promote the germination of grass seeds, and form a green composite protection layer.

[0004] When constructing the three-dimensional vegetation net, it is generally laid on the slope from top to bottom along the slope surface. The adjacent two three-dimensional vegetation nets overlap and lap, and then the lap is fixed by U-shaped nails. Finally, improved soil is backfilled or hydraulic spraying is carried out on the upper part of the three-dimensional vegetation net. When carrying out U-shaped nail reinforcement, in order to ensure the uniform fixation of the three-dimensional vegetation net, it is necessary to arrange the U-shaped nails evenly. In this process, it is necessary to carry out positioning and setting out or arrange them depending on the experience of the construction personnel themselves. The positioning and setting out increase the construction workload, while arranging them depending on the experience of the construction personnel themselves is prone to uneven distribution. Based on this, a slope protection net for water conservancy projects is provided. Content of the Utility Model

[0005] The purpose of the utility model is to provide a slope protection net for water conservancy projects in order to solve the problems in the above background.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A slope protection net for water conservancy projects, including a three-dimensional vegetation net. A plurality of groups of through holes are evenly opened at the two side edges and the middle part of the three-dimensional vegetation net. Each group of through holes includes two through holes. The three-dimensional vegetation net is press-fitted with positioning components through the through holes. The positioning components are used to provide positioning for the installation of the reinforcement components and at the same time increase the compressive strength of the three-dimensional vegetation net.

[0007] The positioning components include positioning cylinder columns and annular pressing sheets.

[0008] The positioning cylinder columns penetrate through the through holes. The annular pressing sheets are symmetrically fixed on the outer sides of the upper and lower ends of the positioning cylinder columns and are closely attached to the upper and lower end faces of the three-dimensional vegetation net.

[0009] Two positioning cylinder columns are used to provide insertion holes for the reinforcement components, and the uniform installation of the reinforcement components is realized through the uniformly distributed positioning components.

[0010] As a further solution of the utility model: The reinforcement component includes a several-shaped bending part and a plugging nail;

[0011] There are two plugging nails, and the two plugging nails are vertically distributed with the several-shaped bending part and are fixed at the bottom of two end corners of the several-shaped bending part;

[0012] The plugging nail penetrates through the positioning cylinder column and inserts into the slope soil layer, and the several-shaped bending part is pressed against the upper surfaces of the annular pressing sheet and the three-dimensional vegetation net to realize the reinforcement and fixation of the three-dimensional vegetation net.

[0013] As a further solution of the utility model: The several-shaped bending part and the plugging nail are integrally formed by a steel bar bending process, and the distance between the two horizontal cross arms of the several-shaped bending part is smaller than the outer diameter of the daily construction hammer.

[0014] As a further solution of the utility model: The through hole is integrally formed on the surface of the three-dimensional vegetation net by a plastic punching process, and the positioning cylinder column is sleeved inside the through hole and the annular pressing sheet is integrally formed by a plastic hot riveting process.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] By setting the reinforcement component, the several-shaped bending part can provide a hammering part for external tools. Compared with the straight structure at the top of the traditional U-shaped nail, the external tool can better hammer the several-shaped bending part, avoiding the situation of missed hammering, further improving the construction convenience. At the same time, the "U" part of the several-shaped bending part is pressed against the surface of the three-dimensional vegetation net, and its pressing area is larger than that of the traditional U-shaped nail. The annular pressing sheet can bear greater tensile force, thereby further improving the stability of the three-dimensional vegetation net.
