Description

Technical Field

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

[0002] At present, slope protection nets are often used in water conservancy construction projects to reinforce the surfaces of river embankments and dams to avoid soil erosion. Especially in water conservancy and hydropower projects, the soil on the slopes that are often washed by water is easily eroded, so artificial slope protection is required. In summer, when there is abundant rain, the river often carries a large amount of sediment, stones and other sundries, which will damage the slope protection net.

[0003] A water conservancy slope protection net with the publication number of CN221167654U achieves the effect of convenient installation and disassembly through a slope protection device assembled by a bottom plate, a frame and a slope protection net. At the same time, adjacent two slope protection devices can insert the fixing block into the inside of the sleeve block by manually pressing the convex block, and then release the convex block randomly. The convex block is clamped into the inside of the groove by the resilience of the torsion spring for clamping and fixing, completing the convenient assembly. When it is necessary to extract a single slope protection net structure, extract the plastic pressing block, and drive the slope protection net structure to extract from the through interface by the plastic cross bar, completing the convenient disassembly. However, the structure of this utility model is complex, and the slope protection net usually needs to be laid in a large area. Therefore, a water conservancy slope protection net with a simple structure and lower manufacturing cost that can be disassembled and assembled is provided. Content of the Utility Model

[0004] The purpose of the utility model is: to solve the problems in the above background technique, the utility model provides a water conservancy slope protection net with a simple structure and lower manufacturing cost that can be disassembled and assembled.

[0005] The utility model specifically adopts the following technical solutions to achieve the above purpose:

[0006] A water conservancy slope protection net includes a river embankment. A slope surface is provided on the side of the river embankment. A number of slope protection geotextile nets are arranged in an array and laid on the surface of the slope surface. The corners of the slope protection geotextile nets overlap with the corners of the other three adjacent slope protection geotextile nets. A clamping plate one is placed at the corner of the lowermost slope protection geotextile net, and a clamping plate two is placed at the corner of the uppermost slope protection geotextile net. Through holes are provided through the clamping plate one and the clamping plate two. Screws are provided below the clamping plate one. The screws pass through the through holes inside the clamping plate one and the clamping plate two and extend out of the clamping plate two. The part of the screw extending out of the clamping plate two is threadedly connected with a nut.

[0007] Further, the slope protection geotextile net is a rectangle with at least * meters * meters.

[0008] Further, a number of through holes are provided in the clamping plate one and the clamping plate two, and the array spacing of the number of through holes is the same as the spacing between the centers of the holes inside the slope protection geotextile net.

[0009] Furthermore, the through holes are provided as straight slots, the center spacing of the straight slots is the same as the center spacing of the holes inside the slope protection geonet, and the inclinations of the two ends of the straight slots extend outwards.

[0010] Furthermore, a protective cover is sleeved on the outer surface of the clamping plate 2, the bottom end of the protective cover wraps around the side surface of the clamping plate 2, a clamping block is fixedly connected at the center of the bottom edge of the protective cover, and the inner part of the clamping block extends to the bottom of the clamping plate 2.

[0011] Furthermore, the protective cover and the clamping block are made of iron or stainless steel.

[0012] Furthermore, the clamping plate 1, the clamping plate 2, the screw and the nut structure at the corners of some of the slope protection geonets are replaced with reinforcing nails, and the two ends of the reinforcing nails respectively pass through a hole of the slope protection geonet and extend downward, and the reinforcing nails are inserted vertically into the surface of the slope and fixedly connected to the slope.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0023] To make the objectives, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model.

[0024] A kind of water conservancy slope protection net provided by this embodiment is mainly used to solve the problems of complex structure and high construction cost in the comparative document, and provides the following technical solutions, which will be described in detail below in combination with Figures 1 - 5 Make a detailed description:

[0025] A kind of water conservancy slope protection net includes a river embankment 1. A slope surface 2 is provided on the side of the river embankment 1. A plurality of slope protection geonets 3 are arranged in an array and laid on the surface of the slope surface 2. The corners of the slope protection geonets 3 all overlap with the corners of the other three adjacent slope protection geonets 3. A clamping plate one 4 is placed at the corner of the lowermost slope protection geonet 3, and a clamping plate two 5 is placed at the corner of the uppermost slope protection geonet 3. A through hole 6 penetrates through the clamping plate one 4 and the clamping plate two 5. A screw 7 is provided below the clamping plate one 4. The screw 7 passes through the through hole 6 inside the clamping plate one 4 and the clamping plate two 5 and extends out of the clamping plate two 5. The part of the screw 7 extending out of the clamping plate two 5 is threadedly connected with a nut 8.

[0026] As Figures 1 - 5 shown, the slope protection geonet 3 is a rectangle with a size of at least 1 meter * 1 meter. Specifically, by limiting the minimum size of the slope protection geonet 3, it is avoided that its area is too small and greatly increases the laying difficulty of the slope protection geonet 3. During actual use, its area can be increased according to actual needs.

[0027] As Figures 1 - 5 shown, a plurality of through holes 6 are opened in the clamping plate one 4 and the clamping plate two 5. The array spacing of the plurality of through holes 6 is the same as the spacing between the centers of the holes inside the slope protection geonet 3. Specifically, by opening a plurality of through holes 6 and installing screws 7 and nuts 8, the connection points at the corners of the slope protection geonet 3 are increased, making it more firm after installation and less likely to be torn off. The spacing of the through holes 6 is set the same as the spacing of the slope protection geonet 3, so as to ensure that the slope protection geonet 3 will not block the penetration path of the screw 7 when installing the screw 7 and the nut 8.

[0028] As Figures 1 - 5As shown, the through hole 6 is opened as a straight slot, and the center distance of the straight slot is the same as the distance between the centers of the internal holes of the slope protection geogrid 3. The two ends of the straight slot extend outward at an angle of 45 degrees. Specifically, due to the straight slot provided, even if the position of the holes of the slope protection geogrid 3 is offset due to slight unevenness on the laying surface of the slope protection geogrid 3, it can still be effective.

[0029] As Figures 1 - 5 shown, a protective cover 9 is sleeved on the outer surface of the second clamping plate 5. The bottom end of the protective cover 9 wraps the side surface of the second clamping plate 5. At the center of the bottom edge of the protective cover 9, a clamping block 10 is fixedly connected. The inner part of the clamping block 10 extends below the second clamping plate 5. Specifically, by pressing down the protective cover 9, its edge expands slightly outward until the clamping block 10 slides below the second clamping plate 5 to fasten the second clamping plate 5, completing the installation of the protective cover 9, avoiding direct entanglement of sediment, waterweeds, etc. on the screws 7 and nuts 8, and significantly accelerating the rusting speed of the screws 7 and nuts 8 due to long-term rotting and erosion. Moreover, after covering the screws 7 and nuts 8, the aesthetic degree of the device is increased.

[0030] As Figures 1 - 5 shown, the protective cover 9 and the clamping block 10 are made of iron or stainless steel. Specifically, they are set to be made of iron or stainless steel, so that they are not easily damaged when impacted by stones in the water flow, thereby avoiding the situation where the screws 7 and nuts 8 are exposed due to easy damage.

[0031] As Figures 1 - 5 shown, the structures of the first clamping plate 4, the second clamping plate 5, the screws 7 and the nuts 8 at the corners of part of the slope protection geogrid 3 are replaced by reinforcing nails 11. The two ends of the reinforcing nails 11 respectively pass through a hole of the slope protection geogrid 3 and extend downward. The reinforcing nails 11 are vertically inserted into the surface of the slope 2 and fixedly connected to the slope 2. Specifically, the entire device is fixedly connected to the river embankment 1 by driving the installed reinforcing nails 11 into the inside of the slope 2.

[0032] The working process of the present utility model: First, lay the slope protection geogrid 3 at the edge and drive in the reinforcing nails 11. Then, lay the adjacent slope protection geogrid 3, and install structures such as the first clamping plate 4, the second clamping plate 5, the screws 7 and the nuts 8 at the overlapping corners to achieve mutual connection. When laying a certain distance, replace the structures such as the first clamping plate 4 with reinforcing nails 11 and drive them into the slope 2, and so on, to achieve large-area laying of the slope protection geogrid 3. And when a certain part of the slope protection geogrid 3 is damaged, remove the screws 7 and nuts 8 at its four corners or pull out the reinforcing nails 11 to replace it.

[0033] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
