Technical Field

[0001] This application relates to the technical field of slope treatment, and more specifically, to a reinforcement grid for highway slope treatment. Background Technique

[0002] Due to the soil quality and geological settlement factors of highway geotechnical slopes, it is easy for the soil and stones on the slope surface to fall off, resulting in obstacles to the smooth driving of the highway, and the aesthetics of the geotechnical slopes is poor. Therefore, a grid structure is needed to beautify, intercept and protect the geotechnical slopes, and improve the environment of highway geotechnical slopes.

[0003] The prior art document with the publication (announcement) number CN216379474U provides a geogrid connection structure. In the related technology of this device, U-shaped nails are staggered and inserted into the cut and overlapped geogrid strips. After closing the ends of the U-shaped nails, ultrasonic power welding is used and an anti-corrosion coating is applied. The connection process is simple in operation and low in cost.

[0004] Although the above prior art solution can achieve the relevant beneficial effects through the existing technology structure, there are still the following defects: The U-shaped steel nails are used to reinforce and connect the joints of the grid sheets. Not only does it require welding one by one, wasting time, but also the stability of the connection between the geogrid belt and the geotechnical slope cannot be guaranteed.

[0005] In view of this, we propose a reinforcement grid for highway slope treatment. Utility Model Content

[0032] The present application is further described in detail below in conjunction with the accompanying drawings.

[0033] Reference Figures 1-3, a reinforcement grid for highway slope treatment described in the embodiments of the present application, includes: a geocell belt body 1 and a positioning fixing pin 2;

[0034] The positioning fixing pin 2 includes a strip sleeve 21, an insertion rod 22, a closing plate 23 and a tapered column 24;

[0035] The insertion rod 22 is slidably connected between the strip sleeve 21 and the closing plate 23, and is elastically limited to the strip sleeve 21 by a spring member sleeved on its outer part;

[0036] The closing plate 23 is in plug-in fit with the strip sleeve 21;

[0037] The tapered column 24 is fixedly connected to one side of the strip sleeve 21.

[0038] For the reinforcement grid for highway slope treatment, by using the connection between the strip sleeve 21 and the closing plate 23 under the action of the insertion rod 22, the function of outward pulling and sliding turning of the closing plate 23 is realized, so that the connection part of the geocell belt body 1 clamped into the strip sleeve 21 can be pressed and fixed and reinforced, improving the stability of the geocell belt body 1 under tension. And the strip sleeve 21 is connected and limited by the tapered column 24, so that the positioning fixing pin 2 can be inserted into the slope surface of the rock and soil slope for stable connection, improving the stability of the laying, protection and beautification of the geocell belt body 1.

[0039] Refer to Figure 3 and Figure 2 , in the reinforcement grid for highway slope treatment described in the embodiments of the present application, the strip sleeve 21 is arranged in a U-shaped structure, and a compensation column block 25 capable of being in plug-in fit with the closing plate 23 is fixedly connected to one side of the strip sleeve 21.

[0040] For the reinforcement grid for highway slope treatment, by using the strip sleeve 21 arranged in a U-shaped structure, the connection part of the geocell belt body 1 can be sleeved, protecting the stability of the reinforcement of the connection part of the geocell belt body 1. And the compensation column block 25 can not only abut and limit the closing plate 23 that is elastically stretched and plugged and closed with the strip sleeve 21, but also realize the turning of the outward pulled strip sleeve 21, so as to facilitate the positioning fixing pin 2 to be clamped at the connection part of the geocell belt body 1 for reinforcement connection and protection.

[0041] Refer to Figure 4 and Figure 3 , in the reinforcement grid for highway slope treatment described in the embodiments of the present application, the insertion rod 22 includes a U-shaped rod 26. One end of the U-shaped rod 26 is inserted and installed with a screw rod 27, and the other end of the U-shaped rod 26 is sleeved with a positioning ring 28. The positioning ring 28 and the U-shaped rod 26 are connected and limited by a pin 29.

[0042] The reinforcement grid for highway slope treatment forms an insert rod 22 component that can be disassembled and replaced through the cooperation of a U-rod 26, a screw rod 27, a positioning ring 28, and a plug pin 29, facilitating the self-rotation operation of each part of the positioning fixing pin 2.

[0043] Referring to Figure 5 and Figure 3 In the reinforcement grid for highway slope treatment described in the embodiment of the present application, the conical column 24 includes a ring cylinder 3 fixedly installed on one side of the strip sleeve 21. A screw conical column 32 is threadedly fitted inside the ring cylinder 3. A column cylinder 33 is sleeved outside the screw conical column 32. The column cylinder 33 is slidably fitted with the strip sleeve 21 and is also slidably fitted with a plurality of inclined column bars 31 fixedly installed inside the ring cylinder 3. A plurality of annular grooves in an inverted hook structure are formed outside the column cylinder 33.

[0044] In the reinforcement grid for highway slope treatment, by threadedly connecting the screw conical column 32 with the ring cylinder 3, the column cylinder 33 is driven to slide and be limited by a plurality of inclined column bars 31 fixedly installed inside the ring cylinder 3, exposing the inclined column bars 31 installed obliquely, thereby improving the connection stability between the conical column 24 and the rock and soil slope surface. The annular grooves outside the column cylinder 33 can increase the frictional force between the column cylinder 33 and the rock and soil slope surface.

[0045] Working principle: When the positioning fixing pin 2 is fixedly clamped and installed at the connection of the geogrid belt body 1 for reinforcement and protection, the operator manually pulls the closing plate 23 outwards. The outwardly moved closing plate 23 drives the U-rod 26 sleeved with a spring member to extend outwards in a limited manner and compresses the spring member to store energy.

[0046] When the closing plate 23 is disengaged from the clamping limit with the strip sleeve 21, the closing plate 23 is turned outwards to expose the groove of the strip sleeve 21. The unfolded positioning fixing pin 2 is clamped at the connection of the geogrid belt body 1. Then, the reset and flipped closing plate 23 is re-inserted and limitedly fixed with the strip sleeve 21, and the clamping reinforcement between the positioning fixing pin 2 and the connection of the geogrid belt body 1 can be completed.

[0047] Finally, the screw conical column 32 is rotated to be threadedly connected with the ring cylinder 3, driving the column cylinder 33 to slide and be limited by a plurality of inclined column bars 31 fixedly installed inside the ring cylinder 3. After the inclined column bars 31 installed obliquely are exposed, the positioning fixing pin 2 is fixed in the soil layer of the rock and soil slope surface.
