Low slope landslide mass reinforcing structure

Abstract

The utility model relates to the technical field of slope reinforcement, in particular to a low slope landslide mass reinforcement structure which comprises geogrid units connected with each other. The adjacent geogrid units are connected through a plurality of connecting pieces, and the connecting pieces can deform under the stress stretching condition. The connecting piece is fixed on a slope body through an anchor rod; the protective step unit is positioned above the geogrid unit; the adjacent protection step units are clamped with each other; and a drainage ditch structure is clamped to the lowermost protection step unit. The multiple geogrid units are connected with each other and distributed on the surface of the slope body, every two adjacent geogrid units are connected with each other through the corresponding connecting piece, and reinforcement of the slope body can be enhanced by means of the anchor rods. Due to the fact that the connecting pieces are arranged in a local double-layer overlapping mode, when the slope body collapses or slides, the connecting pieces can be stressed and stretched to deform, and the adjacent geogrid units can buffer collapse of the low slope landslide body within a certain range under the action of the connecting pieces which deform into larger circles.

Description

Technical Field

[0001] The utility model relates to the technical field of slope reinforcement, and more specifically, to a low side slope landslide reinforcement structure. Background Art

[0002] Low slopes are widely used in civil engineering. For example, in the design of roadbeds in the fields of highways, railways, and construction, the design and stability analysis of low slopes are very important. Patent No. CN213978997U discloses a low slope landslide reinforcement structure. When the inner anchor head is fixed to the rock layer under the landslide, the prestressed anchor cable reinforces the landslide by tightening the geogrid. When it rains, rainwater seeps into the landslide and falls into the water channel, where it is collected by the water channel, thereby preventing the rainwater from continuing to seep. The rainwater in the water channel flows out of the landslide along the water channel. However, once a landslide occurs, the above-mentioned low slope landslide reinforcement structure will cause the broken slope, the geogrid on its surface, and the imported soil layer to collapse and slide together, causing the entire slope to collapse and slide. Therefore, it still does not play a good role in reinforcing the landslide. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings, the utility model aims to provide a low slope landslide reinforcement structure.

[0004] A low slope landslide reinforcement structure, comprising:

[0005] Interconnected geogrid units; the adjacent geogrid units are interconnected by a plurality of connectors, the connectors being deformable under tension; the connectors being fixed to the slope by anchor rods;

[0006] The protective step unit is located above the geogrid unit; adjacent protective step units are connected to each other; the protective step unit located at the bottom is connected to a drainage ditch structure; and a planting trough is arranged on each protective step unit.

[0007] Furthermore, the geogrid units are arranged adjacent to each other in sequence from top to bottom along the surface of the slope;

[0008] The adjacent edges of two adjacent geogrid units are sleeved with the connecting piece, and the connecting piece is a long fixed belt structure in the unfolded state, and its end connections are fixed to the slope through the anchor rods; the middle part of the connecting piece adopts fixing nails to form a local double-layer structure, which can be stretched when subjected to force and tension to restore the single-layer structure.

[0009] Furthermore, the protective step unit includes a top step unit and a plurality of middle step units.

[0010] Furthermore, a first plate is arranged below the top step unit.

[0011] The middle step unit is provided with a second plate body and a second trough body;

[0012] The first plate is embedded in the second slot, and the first plate can move within a preset distance along the second slot of the middle step unit adjacent to the top step unit;

[0013] The second plate can move within a preset distance along the second groove of the adjacent middle step unit; thereby forming mutual movement between the protective step units, which can buffer the collapse of the slope within a certain range.

[0014] Furthermore, a concrete layer is arranged between the top step unit and the slope surface, and a first movement space is reserved above the first plate;

[0015] A concrete layer is arranged between the middle step unit and the surface of the slope; and a second moving space is reserved above the second plate.

[0016] Furthermore, the middle step unit is also provided with a plurality of planting troughs.

[0017] Furthermore, the drainage ditch structure includes a third trough body, and the second plate body of the lowermost middle stepped unit is embedded in the third trough body and can move within a preset distance along the third trough body.

[0018] Furthermore, the drainage ditch structure is provided with an upward drainage groove.

[0019] Furthermore, the outer side wall of the drainage trough is provided with a plurality of drainage openings.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This low-slope landslide reinforcement structure features multiple interconnected geogrid units arranged on the slope surface. Adjacent geogrid units are connected via connectors. These multiple geogrid units are deployed on the low-slope landslide, and anchor rods are used to enhance the reinforcement of the low-slope landslide. Because the connectors are arranged in a partially overlapping double layer, when a slope collapses or landslide occurs, the connectors are stretched and deformed, forming a larger loop. Adjacent geogrid units, deformed into a larger loop, can cushion the collapse of the low-slope landslide within a certain range, preventing further collapse.

[0022] On multiple geogrid units, multiple protective step units are also arranged, which can move relative to each other to a certain extent. Through the sliding design between the first plate body and the second trough body, and the second plate body and the second trough body, the extension range of each step unit can be increased, which can effectively prevent the slope that has partially collapsed from collapsing again.

[0023] Furthermore, each stepped protective step unit is provided with a number of planting grooves, and green plants are planted in the planting grooves to further reinforce the slope. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] like Figures 1-6 As shown, this embodiment provides a low slope landslide reinforcement structure, comprising interconnected geogrid units 1 and protective step units located above the geogrid units 1. Adjacent geogrid units 1 are interconnected by a number of connectors 2, each of which can deform under tension, and some of the connectors 2 are fixed to the slope 4 by anchor rods 3. Adjacent protective step units are connected to each other, with the bottom protective step unit being connected to a drainage ditch structure 5, and each protective step unit is provided with a planting trough 6.

[0035] Specifically, if Figure 1 、 Figure 5 、 Figure 6 As shown, the geogrid units 1 are arranged adjacent to each other from top to bottom along the surface of the slope 4; the adjacent edges of two adjacent geogrid units 1 are sleeved with connectors 2. Figure 7 As shown, the connector 2, when deployed, is a long, strip-shaped fixing belt structure, connected end to end. Anchor rods 3 pass through the end-to-end connection and the middle of the fixing belt to secure the connector 2 to the slope 4. Furthermore, fixing pins 21 are used in the middle of the connector 2 to form a partially double-layered fixing belt structure. This structural design allows the fixing pins to be stretched and restored to a single-layer structure under tension. The fixing pins can be double-sided rivets, nylon rivets, or other structures that can partially overlap and secure the fixing belt structure.

[0036] In this embodiment, Figures 1-4 As shown, the protective step unit includes a top step unit 7 and several middle step units 8. A first plate 71 is arranged below the top step unit 7, and a second plate 81 and a second trough 82 are arranged below the middle step unit 8. The first plate 71 of the top step unit 7 is embedded in the second trough 82 of the adjacent middle step unit 8 below it. The first plate 71 can move within a preset distance along the second trough 82 of the middle step unit 8 adjacent to the top step unit 7, and the second plate 81 can move within a preset distance along the second trough 82 of the adjacent middle step unit 8; thus, mutual movement between the protective step units is formed, which can buffer slope collapse within a certain range.

[0037] Furthermore, a concrete layer 9 is arranged between the top step unit 7 and the surface of the slope 4 , and a first moving space 72 is reserved above the first plate 71 of the top step unit 7 to facilitate the movement of the first plate 71 in the second trough 82 .

[0038] A concrete layer 9 is arranged between the middle step unit 8 and the surface of the slope 4 . A second moving space 83 is reserved above the second plate 81 of the middle step unit 8 to facilitate the movement of the second plate 81 in the second trough 82 .

[0039] In this embodiment, the middle step unit 8 is further provided with a plurality of planting grooves 6, in which green plants are planted, so as to further reinforce the slope.

[0040] In this embodiment, the drainage ditch structure 5 includes a third trough 51. The second plate 81 of the lowermost middle stepped unit 8 is embedded in the third trough 51 and can move along the third trough 51 within a predetermined distance. The drainage ditch structure 5 defines an upward-facing drainage trough 52, and a plurality of drainage openings 53 are defined on the outer sidewall of the drainage trough 52.

[0041] The present embodiment provides a short slope landslide reinforcement structure, in which a plurality of geogrid units 1 are interconnected and arranged on the surface of the slope 4, and two adjacent geogrid units 1 are interconnected by connectors 2. Since the connectors 2 are arranged in a partially double-layer overlapping manner, when the slope 4 collapses or landslides, the connectors 2 can be stretched and deformed to form a larger circle of connectors 2. Adjacent geogrid units 1, under the action of the connectors 2 deformed into a larger circle, can buffer the collapse of the short slope landslide within a certain range, preventing the short slope landslide from collapsing further. The connectors 2 are also fixed to the slope 4 by anchor rods 3, which can further reinforce the short slope landslide. A plurality of geogrid units are arranged on the short slope landslide, and the anchor rods can be used to strengthen the reinforcement of the short slope landslide. In addition, multiple geogrid units are also arranged with multiple protective step units that can move relative to each other. Through the sliding design between the first plate body 71 and the second trough body 81, and the second plate body 82 and the second trough body 81, when the slope collapses, with the help of the sliding structure design of the first plate body 71 in the second trough body 81, the first plate body 71 of the top step unit 7 slides to and against the side of the second trough body 81 of the adjacent middle step unit 8, and the second plate body 81 of the middle step unit 8 slides in the second trough body 81 of the adjacent middle step unit and slides to and against the side of the second trough body 81. At this time, the extension range of each step unit can be increased, and the slope that has partially collapsed can be effectively prevented from collapsing again.

[0042] In addition, each step-shaped protective step unit is provided with a plurality of planting grooves 6, in which green plants are planted to further reinforce the slope. The edges of each planting groove 6 are concrete steps, which can facilitate the maintenance and conservation of green plants on the slope.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
