Description

Technical Field

[0001] This utility model relates to the technical field of slope protection, and in particular to a combined guided flexible protection structure for steep slopes. Background Technology

[0002] Slope protection refers to a series of engineering measures and technical means to prevent rocks or soil on slopes from sliding, collapsing, or other phenomena caused by natural factors or human activities. These measures aim to improve slope stability, reduce the occurrence of geological disasters, and protect people's lives and property.

[0003] Slope protection systems are mainly divided into two categories: active protection and passive protection. Active protection systems typically use flexible nets such as wire rope nets, ordinary wire mesh, and TECCO high-strength wire mesh to cover the slope or rock that needs protection, in order to limit the weathering and erosion or damage of the slope rock and soil, as well as the collapse of dangerous rocks. Passive protection systems, on the other hand, use structures such as retaining walls and slope protection to control the possible rockfalls within a certain range and reduce their harm to the surrounding environment.

[0004] Traditional active protection nets mainly use single 4*4m steel wire rope woven nets, with anchor points set around the perimeter of each net. If a local collapse or rockfall occurs on the slope, the entire system will be damaged or "bulging" will occur.

[0005] Chinese utility model patent application number CN202421322043.7 discloses a safety protection device for dam slopes, comprising: anchor bolts for fixing to the slope; a protective net for laying on the slope; a first connecting mechanism for connecting the anchor bolts and the protective net, comprising: a connecting block fixedly mounted on the anchor bolts; a connecting rod fixedly mounted on the connecting block; a connecting ring fixedly mounted on the protective net, the connecting ring being sleeved on the connecting rod; and a first limiting component. This solution fixes the protective net with anchor bolts and sets the protective net as multiple independent protective units, thereby improving the overall protective effect of the system and preventing damage to the entire system should a localized collapse or rockfall occur on the slope. However, each protective net requires multiple anchor bolts for fixing, making construction cumbersome, costly, and time-consuming.

[0006] To address the aforementioned issues, this application provides a combined flexible slope protection structure for steep slopes. Utility Model Content

[0007] This utility model provides a combined flexible protection structure for steep slopes, which can leave a certain space for the rolling and sliding of falling rocks. When falling rocks roll and impact the mesh, the mesh can effectively suppress the bounce height of the falling rocks. During the rolling process, the falling rocks generate friction with the mesh and the slope, which continuously reduces the energy of the falling rocks. Finally, the falling rocks are intercepted or guided to a designated area at the foot of the slope, thus achieving the function of rockfall protection.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] This utility model discloses a combined guided flexible protection structure for steep slopes, comprising:

[0010] Multiple support ropes are installed along the slope, both longitudinally and transversely.

[0011] An anchor bolt is located at the end of the support rope and connected to the support rope, and the anchor bolt is anchored into the slope.

[0012] Twisted-pair netting is laid on the slope and connected to support ropes.

[0013] A ring network, which covers and connects to a twisted-pair network.

[0014] This utility model discloses a combined flexible protective structure for steep slopes, wherein the longitudinally and transversely arranged support ropes are connected at their intersections.

[0015] This utility model discloses a combined flexible protective structure for steep slopes, further comprising a buffer device at the end of the support rope arranged laterally.

[0016] This utility model discloses a combined flexible protective structure for steep slopes. Furthermore, the upper end of the longitudinally arranged support rope is connected to the anchor rod, and the lower end is connected to the outermost longitudinal support rope.

[0017] This utility model discloses a combined guided flexible protection structure for steep slopes. Furthermore, the spacing between the lower anchor rods arranged longitudinally is greater than the spacing between the upper anchor rods.

[0018] This utility model discloses a combined flexible protective structure for steep slopes. Further, the support rope includes a transverse main rope, a transverse secondary rope, a longitudinal main rope, and a longitudinal secondary rope. The diameter of the transverse main rope is larger than the diameter of the transverse secondary rope. The transverse main rope is located on the outermost side, and the transverse secondary rope is located between the transverse main ropes.

[0019] The diameter of the longitudinal main pull rope is larger than the diameter of the longitudinal secondary pull rope, and the longitudinal main pull rope and the longitudinal secondary pull rope are alternately arranged.

[0020] This utility model discloses a combined flexible protective structure for steep slopes. Furthermore, a pit is provided on the slope at the end of the anchor rod, and a collar is connected to the end of the anchor rod. Concrete is poured into the pit, and the connection between the collar and the anchor rod is sealed within the concrete. The support rope is connected to the collar.

[0021] This utility model discloses a combined flexible protective structure for steep slopes, wherein the elevation of the collar is lower than the elevation of the slope surface.

[0022] Compared with the prior art, this utility model has the following advantages:

[0023] This application uses anchor bolts around the perimeter and support ropes arranged longitudinally and transversely to form a frame. A twisted-pair net and a ring net are then placed over the slope requiring protection, creating an energy-dissipating and guiding net. The system's own weight applies a pressure perpendicular to the slope surface, while simultaneously allowing space for the rolling and sliding of falling rocks. As rocks roll and impact the net, the net effectively inhibits the bounce height of the rocks. During the rolling process, friction between the rocks and the net and the slope surface continuously reduces the energy of the falling rocks, ultimately intercepting or guiding them to a designated area at the foot of the slope, thus achieving rockfall protection. Compared to traditional active protection nets, this application's active energy-dissipating net uses a ring net as the main net with a more flexible twisted-pair net underneath. The entire system has no anchor bolts in the middle, effectively guiding and protecting against dangerous rocks falling from the slope.

[0024] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

[0029] like Figs. 1-2As shown, this utility model discloses a combined flexible protection structure for steep slopes, including support ropes 1, anchor rods 2, twisted nets 3, and ring nets 4. In this embodiment, the support ropes 1 are steel wire ropes 6, arranged in multiple rows along the slope 5. The intersections of the longitudinally and transversely arranged support ropes 1 are connected by cross rope clamps. In this embodiment, the anchor rods 2 are prestressed anchor rods 2, arranged along the longitudinal and transverse directions at the ends of the support ropes 1, and anchored into the slope 5. The twisted nets 3 cover the slope surface requiring protection and are connected to the support ropes 1 via steel wires 6. The ring nets 4 cover the twisted nets 3 and are connected to the twisted nets 3.

[0030] This application uses four anchor bolts 2 and longitudinally and transversely arranged support ropes 1 to form a frame, covering the slope surface to be protected with twisted net 3 and ring net 4, forming an energy dissipation and guiding net. The system's own weight applies a pressure perpendicular to the slope surface, while leaving a certain space for the rolling and sliding of falling rocks. When falling rocks roll and impact the net, the net can effectively suppress the bounce height of the falling rocks. During the rolling process, the falling rocks generate friction with the net and the slope surface, continuously reducing the energy of the falling rocks, and finally intercepting or guiding the falling rocks to a designated area at the foot of the slope, thus achieving the function of rockfall protection. Compared with traditional active protection nets, the active energy dissipation net of this application uses a ring net 4 as the main net, with a twisted net 3 underneath, which is more flexible. The entire system does not have anchor bolts 2 in the middle, which can effectively guide and protect dangerous rocks within the slope.

[0031] Furthermore, a buffer device 7 is installed at the end of the support rope 1 arranged in the transverse direction. The buffer device 7 can be a hydraulic buffer or a spring buffer, which can buffer the support rope 1 when rockfall occurs and prevent the support rope 1 from being damaged. The upper end of the support rope 1 arranged in the longitudinal direction is connected to the anchor rod 2, and the lower end is connected to the outermost support rope 1 in the vertical direction. The spacing of the lower anchor rods 2 arranged in the longitudinal direction is greater than the spacing of the upper anchor rods 2. Through the above arrangement, a buffering effect is achieved on the longitudinal support rope 1, making the energy dissipation guide net more flexible and the energy dissipation effect better.

[0032] In addition, to ensure the protective and energy dissipation effects of the support rope 1, the support rope 1 includes a transverse main guy rope 1.1, a transverse secondary guy rope 1.2, a longitudinal main guy rope 1.3, and a longitudinal secondary guy rope 1.4. The diameter of the transverse main guy rope 1.1 is larger than the diameter of the transverse secondary guy rope 1.2, and the transverse main guy rope 1.1 is located on the outermost side, while the transverse secondary guy rope 1.2 is located between the transverse main guy ropes 1.1. The diameter of the longitudinal main guy rope 1.3 is larger than the diameter of the longitudinal secondary guy rope 1.4, and the longitudinal main guy rope 1.3 and the longitudinal secondary guy rope 1.4 are arranged alternately.

[0033] A pit is provided on the slope 5 at the end of the anchor rod 2. A collar is connected to the end of the anchor rod 2. The elevation of the collar is lower than the ground elevation of the slope 5. Concrete is poured into the pit. The connection between the collar and the anchor rod 2 is sealed in the concrete. The support rope 1 is connected to the collar to ensure the restraining effect of the support rope 1 on the protective net.

[0034] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
