Description

Technical Field

[0001] This utility model relates to the field of ecological restoration technology, specifically to an ecological grid structure for rock slope restoration. Background Technology

[0002] Ecological grid structure is an engineering structure applied to rock slope restoration. It combines geosynthetic or natural materials with plant planting and soil improvement to form a composite system that has both slope stability and ecological restoration functions. Traditional grid structures usually have problems such as insufficient fixation effect, poor installation convenience and limited ecological adaptability.

[0003] The utility model patent with announcement number CN207484399U discloses an ecological grid structure for slope restoration, including a slope, a concrete revetment on the outer side of the slope, a capping on the top of the concrete revetment, a brick grid below the capping, a concrete seal between the brick grids, and an anchor cap on the left side of the concrete seal.

[0004] Although this utility model can connect the colluvial gravel, residual gravel, alluvial gravel, and sandy slate of the slope into a whole, and then add a protective net to prevent it from being washed away by rainwater, in complex rock terrain, its fixing components are difficult to penetrate into the rock mass to form a stable connection, which makes the grid structure susceptible to loosening due to slope soil displacement or external forces. Utility Model Content

[0005] The purpose of this invention is to provide an ecological grid structure for rock slope restoration, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An ecological grid structure for rock slope restoration includes four mounting blocks arranged in a matrix. A cylindrical block is fixed to the bottom surface of each mounting block. A connecting plate is fixed between adjacent mounting blocks, and a grid frame is fixed between the four connecting plates. A receiving cavity is formed in the center of each cylindrical block, and a reinforcement mechanism is installed within the receiving cavity to enhance the fixing effect. The reinforcement mechanism includes a turntable and several inserts. The turntable is rotatably connected to the receiving cavity, and the inserts are regularly arranged around the turntable. Connecting rods are hinged to the upper and lower surfaces of one end of each insert located within the receiving cavity, and the other end of each connecting rod is hinged to the turntable away from the edge.

[0007] Preferably, the cylindrical block is rotatably connected to a rotating shaft at the center of the bottom surface of the receiving cavity, and the rotating shaft is fixedly connected to the turntable.

[0008] Preferably, the top end of the rotating shaft extends above the mounting block, and a knob is fixed to the top end of the rotating shaft.

[0009] Preferably, a number of limiting cylinders are regularly fixed on the outer wall of the cylindrical block, and the limiting cylinders correspond one-to-one with the insert blocks, with the insert blocks slidably connected to the corresponding limiting cylinders.

[0010] These three settings ensure synchronous power transmission through the fixed connection between the shaft and the turntable. The exposed knob design facilitates quick operation by construction personnel using tools, improving installation efficiency. The sliding limit of the insert block by the limit cylinder reduces its shaking during the expansion process.

[0011] Preferably, a protective frame is fixed at the center of the top surface of the mounting block, the knob is located inside the protective frame, and a cover is fastened to the top of the protective frame.

[0012] This feature creates a sealed space to protect the knob through a protective frame and cover, extending its service life.

[0013] Preferably, a conical head is fixed to the bottom surface of the cylindrical block, and the side of the insert block away from the turntable is set in a conical shape.

[0014] This feature reduces resistance during insertion by using a conical head and a conical end of the insert, thus reducing the workload for construction workers.

[0015] Preferably, a number of ground nails are provided below the connecting plate, with the ground nails on the same side arranged at equal intervals.

[0016] Preferably, the connecting plate is threaded with a number of bolts, each bolt corresponding to a ground nail, and the top of each ground nail is fixedly connected to the corresponding bolt.

[0017] These two settings enhance adaptability to complex terrain by controlling the insertion depth of the ground stakes with bolts.

[0018] Compared with the prior art, the beneficial effects of this utility model are: In this utility model, the turntable in the reinforcement mechanism is linked to the knob via a rotating shaft. Rotating the knob can drive the turntable to rotate, and through the connecting rod, the insert block expands outward along the limiting cylinder and is inserted into the gap of the rock slope to form a multi-directional mechanical lock, which significantly enhances the connection strength between the grid structure and the slope and avoids displacement caused by slope deformation.

Detailed Implementation

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Please see Figure 1 and Figure 2 The present invention provides the following technical solution: An ecological grid structure for rock slope restoration includes four mounting blocks 100 arranged in a matrix. A cylindrical block 101 is fixed to the bottom surface of each mounting block 100. A connecting plate 200 is fixed between adjacent mounting blocks 100, and a grid frame 300 is fixed between the four connecting plates 200. A receiving cavity 1010 is formed in the middle of each cylindrical block 101. A reinforcing mechanism 500 is installed within the receiving cavity 1010 of each cylindrical block 101 to enhance the fixing effect. The reinforcing mechanism 500 includes a turntable 502 and several insert blocks 504. 502 is rotatably connected to the receiving cavity 1010. Several insert blocks 504 are regularly arranged around the turntable 502. The upper and lower surfaces of one end of the insert block 504 located in the receiving cavity 1010 are hinged with connecting rods 505. The other end of the connecting rod 505 is hinged to the turntable 502 away from the edge, so that the cylindrical block 101 can penetrate into the interior of the slope. The rotation of the turntable 502 drives the insert block 504 to expand along the connecting rod 505 and insert into the slope gap, forming a multi-directional mechanical lock, which significantly enhances the connection strength between the grid structure and the slope and avoids displacement caused by slope deformation.

[0022] In this embodiment, please refer to Figure 1 and Figure 2 A rotating shaft 501 is rotatably connected to the cylindrical block 101 at the center of the bottom surface of the receiving cavity 1010. The rotating shaft 501 is fixedly connected to the turntable 502. The rotating shaft 501 can drive the turntable 502 to rotate by driving the rotating shaft 501, providing a power transmission path for the expansion of the insert block 504, making the operation of the reinforcement mechanism 500 more convenient and stable.

[0023] Specifically, the top of the rotating shaft 501 extends above the mounting block 100, and a knob 506 is fixed at the top of the rotating shaft 501. The knob 506 is exposed above the mounting block 100, which makes it easy for people to manually rotate the rotating shaft 501, thereby controlling the rotation of the turntable 502, realizing the expansion and contraction of the insertion block 504, and improving the convenience and controllability of operation.

[0024] Furthermore, several limiting cylinders 503 are regularly fixed on the outer wall of the cylindrical block 101. The limiting cylinders 503 and the insert blocks 504 correspond one to one. The insert blocks 504 are slidably connected in the corresponding limiting cylinders 503. The limiting cylinders 503 provide sliding tracks for the insert blocks 504 to ensure that the insert blocks 504 move in a fixed direction when expanding or contracting, and avoid deviation.

[0025] In this embodiment, please refer to Figure 1 and Figure 2 A protective frame 103 is fixed at the center of the top surface of the mounting block 100. The knob 506 is located inside the protective frame 103. A cover 104 is fastened to the top of the protective frame 103. The protective frame 103 and the cover 104 can protect the knob 506 from impacts or corrosion from external factors such as slope gravel and rainwater, prevent the knob 506 from rusting or being damaged, and ensure that the reinforcement mechanism 500 remains operable for a long time.

[0026] In this embodiment, please refer to Figure 1 and Figure 2 A conical head 102 is fixed on the bottom surface of the cylindrical block 101. The side of the insert block 504 away from the turntable 502 is set as conical. The conical head 102 can reduce the resistance when the cylindrical block 101 is inserted into the slope, making it easier to position and insert quickly. The conical end of the insert block 504 can more easily wedge into the slope gap, enhancing the firmness of the mechanical locking, while reducing the wear of the insert block 504 when it is inserted.

[0027] In this embodiment, please refer to Figure 1 Several ground nails 401 are installed below the connecting plate 200. Several ground nails 401 on the same side are arranged at equal intervals. The ground nails 401 are inserted into the slope soil or rock crevices to form additional fixing points with the connecting plate 200. Through multi-point mechanical anchoring, the horizontal stability of the grid structure is further enhanced, and the overall structure is prevented from sliding along the slope.

[0028] Specifically, the connecting plate 200 is threaded with several bolts 400, each bolt 400 corresponding to a ground nail 401. The top of the ground nail 401 is fixedly connected to the corresponding bolt 400. The bolt 400 and the ground nail 401 are fixedly connected. The insertion depth of the ground nail 401 can be adjusted through the threaded connection to adapt to the terrain of different rock slopes. At the same time, the tightening effect of the bolts 400 can ensure the connection strength between the ground nail 401 and the connecting plate 200 and prevent the ground nail 401 from loosening and falling off.

[0029] When using the ecological grid structure for rock slope restoration of this utility model, the installation block 100 is placed on the slope surface according to the marked position, so that the conical head 102 on the bottom surface of the cylindrical block 101 is aligned with the slope crack or weak rock layer. The cylindrical block 101 is initially inserted into the slope by hammering or mechanical pressure, and the tip of the conical head 102 is used to reduce the insertion resistance. Open the cover 104 at the top of the protective frame 103, manually rotate the knob 506, and drive the turntable 502 in the receiving cavity 1010 to rotate through the rotating shaft 501. When the turntable 502 rotates, it pushes the insert 504 outward along the limiting cylinder 503 through the connecting rod 505, so that the conical end of the insert 504 is wedged into the crack of the rock slope, forming a multi-directional mechanical lock. After confirming that the insert 504 is fully inserted and secured, stop rotating the knob 506 and fasten the cover 104 onto the protective frame 103 to prevent the knob 506 from being corroded by the outside or accidentally rotated. The top of the ground nail 401 is threaded to the connecting plate 200 by bolt 400. Tighten the bolt 400 to adjust the insertion depth of the ground nail 401, ensuring that the ground nail 401 and the connecting plate 200 form a stable anchor point, thereby enhancing the horizontal anti-slip capability of the grid structure. Fill the spaces enclosed by the grid frame 300 with soil suitable for plant growth, sow grass seeds or plant climbing plants, and use the supporting effect of the grid frame 300 to promote the integration of vegetation roots with the slope, so as to achieve the dual functions of slope stability and ecological restoration.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
