Description

Technical Field

[0001] The utility model relates to the field of slope protection, and specifically relates to a passive protection system applied to a dangerous rock slope. Background Technique

[0002] Dangerous rock slopes are extremely prone to geological disasters such as collapses and landslides. In order to reduce the probability of disasters and ensure the safety of roads, residential areas and other infrastructure, the protection of dangerous rock slopes is crucial.

[0003] At present, passive protection measures are usually adopted to protect dangerous rock slopes. After the existing passive protection net is anchored on the cast-in-place foundation, although it can play a certain passive protection role, due to the inability to evenly disperse the external impact force, the protection effect in some areas is poor.

[0004] Therefore, to solve the above problems, there is an urgent need for a new passive protection system applied to dangerous rock slopes, which can more evenly disperse and bear the external impact force and improve the overall protection effect. Content of the Utility Model

[0005] In view of this, the purpose of the utility model is to overcome the defects in the prior art and provide a passive protection system applied to dangerous rock slopes, which can more evenly disperse and bear the external impact force and improve the overall protection effect.

[0007] Furthermore, the unit protection net is fixed to the dangerous rock slope through anchor points; the anchor points are connected to the corresponding connection nodes of the unit protection net through connection ropes.

[0008] Furthermore, the six side edges of the unit protection net and the connection ropes are all made of steel wires; the steel wire includes a steel wire body and a plurality of barbs arranged on the steel wire body.

[0009] Furthermore, the connection node includes a plurality of elastic connectors; the elastic connectors are arranged at the ends of the steel wire body.

[0010] Furthermore, the elastic connector can be disconnected.

[0011] Furthermore, it further includes an early warning unit; the early warning unit includes a tension detector, a controller and an LED indicator light;

[0012] The tensile detector is arranged on the unit protection net, and its signal output end is connected to the controller, and the control output end of the controller is connected to the LED indicator light.

[0013] Furthermore, the early warning unit further includes a rainfall detector arranged on the dangerous rock slope; the signal output end of the rainfall detector is connected to the controller.

[0014] The beneficial effects of the present utility model are as follows: A passive protection system applied to a dangerous rock slope disclosed by the present utility model can effectively resist rock falling and slope deformation by adopting a protection net with a hexagonal honeycomb structure, and can disperse and bear external impact forces more evenly, thereby improving the overall protection effect. In addition, the hexagonal honeycomb structure also has good water permeability, which helps to maintain the natural drainage of the slope and reduce potential safety hazards caused by water accumulation.

[0021] The following further describes the present utility model in conjunction with the drawings of the specification, as shown in the figure:

[0022] The passive protection system applied to the dangerous rock slope of the present utility model includes a passive protection net arranged on the dangerous rock slope; the passive protection net includes a plurality of unit protection nets, and adjacent unit protection nets are connected through a connection node 4; the unit protection net is a hexagonal honeycomb structure.

[0023] The utility model adopts a unit protection net with a hexagonal honeycomb structure, which has excellent mechanical properties, can disperse and bear external impact forces more evenly, and improve the overall protection effect. In addition, the hexagonal structure has better flexibility and adaptability, can better fit the irregular slope terrain, and thus improve the adaptability and effectiveness of the protection system. The adjacent unit protection nets are connected through the connection nodes 4, making the protection net more integral, reducing the protection blind area, and effectively covering a wider range of slope areas. In addition, the hexagonal honeycomb structure also has good water permeability, which helps to maintain the natural drainage of the slope and reduce the potential safety hazards caused by water accumulation.

[0024] In this embodiment, as Figure 3 shown, the unit protection net is fixed to the dangerous rock slope through the anchor points 3; the anchor points 3 are connected to the corresponding connection nodes 4 of the unit protection net through connecting ropes. Among them, the anchor points 3 are respectively connected to the six connection nodes 4 belonging to the unit protection net through six connecting ropes.

[0025] Through the above settings, the passive protection net is stably set on the slope. In order to fix the protection net on the slope, appropriate anchoring positions need to be selected. These anchoring positions are usually located in areas where the rock is relatively intact and has high strength to ensure the stability and durability of the anchoring. In the case where suitable anchoring positions cannot be directly found, an anchoring agent can be used to fix the anchoring device on the rock to form artificial anchor points 3.

[0026] In this embodiment, the six side edges of the unit protection net and the connecting ropes are all made of steel wires; as Figure 2 shown, the steel wire includes a steel wire body 1 and a number of barbs 2 arranged on the steel wire body 1.

[0027] Through the above settings, these steel wires form the skeleton of the entire protection net. On the steel wires, there are also barbs 2 attached. These barbs 2 can increase the friction between the protection net and the dangerous rock, preventing the dangerous rock from slipping easily when being impacted. The connection method between the barbs 2 and the steel wire body can be welding or mechanical connection, ensuring the firmness and reliability of the connection.

[0028] In this embodiment, as Figure 4 shown, the connection node 4 includes a number of elastic connectors 41; the elastic connectors 41 are arranged at the ends of the steel wire bodies. Among them, one elastic connector 41 is arranged on each steel wire body.

[0029] By setting the elastic connecting member 41, when the protective net is impacted by rocks or landslides, it can absorb and relieve the impact force, reduce the damage to the anchoring points 3 and the overall structure, enhance the stability and impact resistance of the system, extend the service life of the system, and at the same time, prevent the connection points from cracking or falling off due to the instantaneous strong impact force, improving the reliability of the overall protection system.

[0030] In this embodiment, the elastic connecting member 41 can be disconnected. Among them, the elastic connecting member 41 can adopt an existing fusing protection device (which can be composed of alloy materials such as springs). When the force received by the elastic connecting member 41 is greater than its bearing capacity, the elastic member will break and curl back due to inertia to wrap the rock or stone, further improving the reliability of the protection system.

[0031] In this embodiment, the passive protection system of the present utility model further includes a warning unit; the warning unit includes a tensile force detector, a controller, and an LED indicator light;

[0032] The tensile force detector is arranged on the unit protective net, and its signal output end is connected to the controller, and the control output end of the controller is connected to the LED indicator light. Among them, the tensile force detector can adopt existing tensile force testers, tensile force measuring instruments, etc., for detecting the force received by the unit protective net; the controller can adopt an existing single-chip microcomputer controller for processing the tensile force signal and controlling the display of the LED indicator light.

[0033] Through the above settings, when there are more falling rocks, the alarm state can be displayed in time through the LED indicator light, thereby reminding passing vehicles or not allowing vehicles to pass during the current period, thus ensuring driving safety.

[0034] In this embodiment, the warning unit further includes a rainfall detector arranged on the dangerous rock slope; the signal output end of the rainfall detector is connected to the controller, and the control output end of the controller is connected to the LED indicator light.

[0035] Through the above settings, when the rainfall detector detects heavy rainfall in a short period of time, a control signal is also sent to the LED indicator light through the controller, and a reminder message is sent through the LED indicator light to remind passing vehicles to form a warning.

[0036] It should be noted that in order to ensure the continuous normal operation of the warning unit, a power supply module is further included, and the power supply module can adopt an existing solar panel. The solar panel is used to supply power to the LED indicator light, various detectors, etc.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
