Description

Technical Field

[0001] This invention relates to the field of geotechnical engineering protection technology, specifically a slope fixing and protection device. Background Technology

[0002] Steep slopes, due to their poor geological stability, are prone to rockfall hazards. The combination of anchor bolts and wire mesh is a commonly used passive protection method in engineering. This system uses anchor bolts to fix the wire mesh, forming a protective net to intercept or restrain falling rocks. However, in practical applications, the inherent defects of rigid connection design often lead to a decrease in protective effectiveness. The core problem of rigid connections is insufficient terrain adaptability. Steep slopes are often accompanied by weathering of rock strata and the development of joints, forming numerous protrusions, depressions, or slope bends, creating complex terrain. The rigid connection between anchor bolts and wire mesh cannot flexibly deform with the terrain undulations. During installation, the mesh is easily suspended in depressions and over-tensioned in protrusions, resulting in gaps of varying sizes. These gaps become entry points for falling rocks to penetrate the protection system, especially failing to intercept small to medium-sized rocks. Traffic hazards caused by rocks leaking through these gaps have occurred multiple times in mountain highway slope protection projects.

[0003] Insufficient flexural strength at the connection points is also a significant issue. During rockfall impacts, the impact force is transmitted through the wire mesh to the anchor joints. The rigid connection cannot buffer the energy, causing stress concentration at the joints. If the kinetic energy of the falling rock is high, or if there is continuous micro-vibration on the slope, the welded joints and snap-fit ​​connections between the anchors and the mesh are prone to brittle fracture. Furthermore, long-term weathering leads to anchor corrosion and mesh fatigue, further reducing connection strength. In extreme cases, this may cause localized failure of the protective system or even expand the slope instability area.

[0004] Traditional metal components for slope protection generally have the following structural problems: steep slopes are prone to rockfalls, and the rocks are fixed with anchors and wire mesh. The anchors and wire mesh are mostly rigidly connected, which is difficult to adapt to complex and undulating slope terrain and easily creates protective gaps. The anchors are easily bent during installation and cannot be replaced, resulting in a reduction of fixing points for the wire mesh. Summary of the Invention

[0005] This invention aims to solve the problem that the fixing points of wire mesh and rivets cannot be flexibly adjusted, and to solve the problem that when workers use hammers to drive nails into the cracks of rock walls on slopes, some rivets bend and cannot be flexibly replaced due to the traditional rigid welding of wire mesh and fixing rivets.

[0006] A slope fixing and protection device includes a wire mesh, on which multiple rivets are fastened. Each rivet has a disc handle at the top and a nail post fixedly connected to the bottom of the disc handle. A hook lock is fixedly connected to the other side wall of the nail post. A fixed shaft is fixedly connected to one end of the lock frame of the hook lock. The other end of the lock frame is attached to the inclined side wall of one end of the lock post. One end of the lock post is provided with a rotating shaft, which is rotatably connected to the fixed shaft.

[0007] Multiple support nails are fixedly connected to one side of the nail post, and the bottom end of each support nail is a sharp needle tip.

[0008] The intersections of the wire mesh are fastened to the hook locks of each rivet.

[0009] The wire mesh is fixed to the slope by multiple rivets.

[0010] A spring is also fixedly connected to the inner side wall of one end of the lock frame.

[0011] The other end of the spring is fixedly connected to the inner wall of the lock pin.

[0012] The locking pin is a permanent magnet.

[0013] The lock frame is a permanent magnet.

[0014] The spring is made of copper.

[0015] The outer wall of the rivet is coated with a layer of anti-corrosion paint.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The rivets in this device can be removed from the wire mesh and flexibly fixed at various positions on the wire mesh according to the size of the slope rock. The rivets have needle points, which, together with the rivets, form an auxiliary support frame structure, which is beneficial to the stability of the connection between the wire mesh and the slope.
