Description

Technical Field

[0001] The utility model belongs to the technical field of slope protection, and particularly relates to a gabion retaining wall for protecting steep slopes of mine pits. Background Technique

[0002] A gabion retaining wall is a new type of flexible retaining technology. It is mainly a retaining and protecting structure formed by filling gabion cages with stones meeting the design requirements of particle size and laying them layer by layer. Gabion cages are usually mechanically woven from low-carbon steel wires or low-carbon steel wires wrapped with polyvinyl chloride on the outside, with a hexagonal double-twisted shape on the outside, having high corrosion resistance and strength. It is similar to the bamboo-strip stone cages used in ancient China. Its structural stability mainly relies on its own gravity, and it is essentially a gravity retaining wall. The formation of a mine pit is usually an excavation activity carried out by humans to obtain mineral resources. As the ore is mined, a mine pit is gradually formed. The existence of a mine pit generally forms a steep slope, and a gabion retaining wall needs to be set up to prevent landslides.

[0003] Before the existing gabion nets are laid, they are generally assembled into a grid pattern first. When applied to a steep slope, they are generally perpendicular to the steep slope. Due to being on an inclined surface, the gabion net is prone to being compressed and deformed after being filled with stones. Content of the Utility Model

[0004] To solve the problems raised in the above background technique, the utility model provides a gabion retaining wall for protecting steep slopes of mine pits, and solves the problem that it is generally perpendicular to the steep slope when applied to the steep slope.

[0005] To achieve the above object, the utility model provides the following technical solution: A gabion retaining wall for protecting steep slopes of mine pits, including a first gabion net, a base layer and a second gabion net. A support rod is fixedly connected to the bottom of the first gabion net. A connecting seat is movably installed on the upper surface of the base layer. Both ends of the support rod are inserted into the connecting seat. A connecting plate is fixedly connected to the surface of the first gabion net. A screw rod is inserted into the inside of the connecting plate, and a nut is threadedly installed on the surface of the screw rod.

[0006] Preferably, grid bars are fixedly connected to the lower surface of the base layer.

[0007] Preferably, a screw is threadedly connected to the inside of the connecting seat.

[0008] Preferably, every two nuts are in a group and are respectively located on both sides of the connecting plate.

[0009] Preferably, the connecting plates are symmetrically and vertically arranged in an array.

[0010] Preferably, the screw rod is perpendicular to the first gabion net.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The gabion retaining wall for protecting the steep slopes of mine pits can be fixed on the base layer through screws by means of the connecting seat. The support rod at the bottom of the first gabion net can be inserted into the connecting seat, which can not only prevent the first gabion net from moving, but also facilitate the adjustment of the angle of the first gabion net. The first gabion net can be adjusted to be perpendicular to the ground plane through the support rod, thus avoiding deformation caused by inclined pressure after filling with stones. Through the screw rod, it can pass through two connecting plates at the same height, and thus cooperate with the nut to improve the stability of the first gabion net.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4, the present utility model provides the following technical solution: A gabion retaining wall for protecting steep slopes in a mine pit, comprising a first gabion mesh 1, a base layer 2 and a second gabion mesh 3. A support rod 4 is fixedly connected to the bottom of the first gabion mesh 1. A connecting seat 5 is movably installed on the upper surface of the base layer 2. Both ends of the support rod 4 are inserted into the connecting seat 5. A connecting plate 6 is fixedly connected to the surface of the first gabion mesh 1. A screw rod 7 is inserted into the connecting plate 6. A nut 8 is threadedly installed on the surface of the screw rod 7.

[0021] In this embodiment, through the setting of the connecting seat 5, it can be fixed on the base layer 2 by the screw 10. The support rod 4 at the bottom of the first gabion mesh 1 can be inserted into the connecting seat 5, which can not only prevent the first gabion mesh 1 from moving, but also facilitate the adjustment of the angle of the first gabion mesh 1. The first gabion mesh 1 can adjust the angle to be perpendicular to the ground plane through the support rod 4, thereby avoiding deformation caused by inclined pressure after filling with stones. Through the screw rod 7, it can pass through two connecting plates 6 at the same height, so that cooperating with the nut 8 is beneficial to improving the stability of the first gabion mesh 1.

[0022] Specifically, a grid strip 9 is fixedly connected to the lower surface of the base layer 2. Through the setting of the grid strip 9, it is beneficial to improve the friction between the lower surface of the base layer 2 and the slope, thereby improving the anti-slip performance.

[0023] Specifically, a screw 10 is threadedly connected inside the connecting seat 5. The connecting seat 5 can be fixed by the screw 10. The bottom end of the screw 10 can be spirally inserted into the base layer 2, so that the connecting seat 5 can be fixed on the base layer 2.

[0024] Specifically, every two nuts 8 are in a group and are respectively located on both sides of the connecting plate 6. Through the setting of every two nuts 8 in a group, the screw rod 7 can be effectively fixed.

[0025] Specifically, the connecting plates 6 are symmetrically and vertically arranged in an array. Through the setting of the connecting plates 6, it is convenient for the screw rod 7 to pass through, so as to facilitate connecting each first gabion mesh 1.

[0026] Specifically, the screw rod 7 is perpendicular to the first gabion mesh 1, so that the screw rod 7 can be in a horizontal state, and thus the screw rod 7 can pull each first gabion mesh 1 and support and fix it.

[0027] Working principle or usage process of the utility model: When the utility model is in use, first lay the base layer 2 on the steep slope of the mine pit. The grid bars 9 can increase the friction between the lower surface of the base layer 2 and the slope, thereby improving the anti-slip property. Then fix the connecting seat 5 on the base layer 2 through the screw 10. When installing the connecting seat 5, the support rod 4 at the bottom of the first gabion net 1 needs to be inserted into the connecting seat 5, so as to prevent the first gabion net 1 from moving. Moreover, the first gabion net 1 can be adjusted in angle through the connecting seat 5. Then adjust the angle of the first gabion net 1 through the support rod 4 to be perpendicular to the ground plane. Next, pass the screw rod 7 through two connecting plates 6 at the same height, and then tighten each nut 8 to improve the stability of the first gabion net 1. Then insert the second gabion net 3, and the edge can be connected to the first gabion net 1 through wire. Then the gabion net can be filled with stones. Since the first gabion net 1 is perpendicular to the ground plane, no deformation will occur due to inclined pressure after filling with stones.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. This specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the relevant technical field can understand and utilize the present utility model well.
