Description

Technical Field

[0001] The invention relates to the technical field of highway slope reinforcement, and in particular to a highway slope protection device. Background Art

[0002] In recent years, with the increase in the intensity of infrastructure construction in my country, the scale of highway construction has become larger and larger. However, some highways did not take into account the local geological conditions well in the early stages of construction. In addition, geological disasters have occurred frequently in recent years, which has led to safety risks on the slopes of some highways.

[0003] It can be understood that the highway slope refers to the slope with a certain slope made on both sides of the roadbed to ensure the stability of the roadbed. According to the cause of formation, it can be divided into artificial slopes and natural slopes; according to the lithology, it can be divided into soil slopes and rock slopes; according to the rock structure, it can be divided into layered structure slopes, block structure slopes, and mesh structure slopes; according to the relationship between the inclination of the rock layer and the slope direction, it can be divided into forward slopes, reverse slopes and vertical slopes; according to the service life, it can be divided into permanent slopes and temporary slopes.

[0004] In the prior art, the highway slope structure is usually a slope, with a layer of tiles laid on the slope surface, and some green plants installed in the gaps of the tiles to prevent soil loss on the slope. Such a slope structure is simple and easy to construct. However, for mountain highways, due to the high mountains on both sides of the highway, the inclined slope can only be a part of the lower end. The existing slope structure is not strong enough and lacks protective components, making it difficult to ensure the safety of pedestrians on the highway. At the same time, the existing slope structure lacks an early warning system, and cannot warn pedestrians and vehicles on the highway when the slope is abnormal, resulting in low safety of the slope. Summary of the invention

[0005] In response to the problems in the prior art, the highway slope protection device provided by the present invention can prevent falling foreign objects from directly hitting the highway, effectively ensure the safety of vehicles and pedestrians on the highway, and warn pedestrians on the highway when abnormalities occur on the slope, thereby improving the safety of the slope.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] The present invention provides a highway slope protection device, comprising:

[0008] Slope protection mechanisms are installed on the slopes at the bottom of the mountains on both sides of the highway;

[0009] A mountain protection mechanism is arranged at the upper end of the mountain slope and is located above the slope protection mechanism; a preset angle with the vertex facing downward is formed between the mountain protection mechanism and the mountain, and a retractable opening is formed between the bottom of the mountain protection mechanism and the mountain;

[0010] The early warning mechanism is used to monitor the mountain humidity in real time and issue an early warning when the mountain humidity exceeds a preset threshold.

[0011] In one embodiment, the mountain protection mechanism includes:

[0012] At least two mounting beams fixed to the mountain;

[0013] at least two mounting rods fixed to the top of the mounting beam;

[0014] at least two telescopic assemblies disposed at the bottom of the mounting beam;

[0015] The wire mesh has an upper portion fixedly connected to the mounting rod, and a lower portion fixedly connected to the telescopic assembly; the telescopic assembly can be telescoped in a horizontal direction.

[0016] In one embodiment, the telescopic assembly includes:

[0017] A sliding sleeve, arranged inside the mounting beam;

[0018] A sliding rod, disposed in the sliding sleeve;

[0019] The spring is sleeved on the slide bar.

[0020] In one embodiment, a blocking piece is provided at one end of the sliding rod located at the sliding sleeve, and cooperates with the sliding opening of the sliding sleeve to limit the spring.

[0021] In one embodiment, the slope protection mechanism comprises:

[0022] A concrete layer, laid on the bottom surface of the mountain;

[0023] A fixed rib is arranged on the surface of the concrete layer;

[0024] A water tank is arranged on the surface of the concrete layer.

[0025] In one embodiment, the fixing rib is triangular in shape and is spaced apart from the water tank on the surface of the concrete layer;

[0026] The slope protection mechanism also includes:

[0027] A circular flower bed is arranged in the fixing rib.

[0028] In one embodiment, the early warning mechanism includes:

[0029] A humidity sensor, whose probe is set inside the mountain, is used to monitor the humidity inside the mountain in real time;

[0030] A PLC controller is used to receive the internal humidity of the mountain sent by the humidity sensor and issue an alarm instruction according to the internal humidity of the mountain;

[0031] The alarm is used to receive the alarm instruction sent by the PLC controller and issue an early warning.

[0032] In one embodiment, the highway slope protection device further comprises:

[0033] The drainage ditch is arranged between the slope protection mechanism and the highway.

[0034] In one embodiment, the highway slope protection device further comprises:

[0035] A protective strip is arranged along the drainage ditch to prevent vehicles from leaving the road.

[0036] In one embodiment, the alarm is arranged on the protection belt.

[0037] From the above description, it can be seen that the highway slope protection device provided by the embodiment of the present invention includes: a slope protection mechanism, which is arranged on the bottom slope of the mountain on both sides of the highway; a mountain protection mechanism, which is arranged at the upper end of the mountain slope and is located on the upper part of the slope protection mechanism; a preset angle with the vertex facing downward is formed between the mountain protection mechanism and the mountain, and the bottom of the mountain protection mechanism forms a retractable opening with the mountain; an early warning mechanism is used to monitor the humidity of the mountain in real time, and when the humidity of the mountain exceeds the preset threshold, an early warning is issued. Specifically, the highway slope protection device provided by the embodiment of the present invention has the following beneficial effects:

The gutter facilitates the rapid discharge of rainwater. The expansion rod can ensure that the concrete layer is tightly fixed to the slope. A variety of slope reinforcement components are provided to improve the strength of the highway slope.

[0039] 2. When foreign objects fall from the top of the mountain, the foreign objects fall between the wire mesh and the mountain under the action of the wire mesh, and then slide down along the wire mesh. The lower end of the wire mesh is deformed by gravity. At the same time, the lower end of the wire mesh pulls the slide bar to slide outward along the slide sleeve, and the spring is compressed to open the opening between the lower end of the wire mesh and the mountain, so that the foreign objects slide along the concrete layer, thereby preventing foreign objects from falling directly from a high altitude onto the road. A protective component with an upper opening is provided, which can change the trajectory of foreign objects falling from the mountain, prevent falling foreign objects from directly hitting the road, and effectively ensure the safety of pedestrians on the road.

[0040] 3. The humidity sensor detects the humidity of the mountain in real time and transmits the detected data to the PLC controller. The PLC controller integrates and judges the received data. When the humidity of the mountain is greater than the value set inside the PLC controller, it means that there is serious water seepage inside the mountain and landslides may occur. At this time, the PLC controller controls the alarm to work, and the alarm sounds an alarm to remind pedestrians on the road that there is a risk of landslide on the road ahead. It provides an automatic early warning device that can monitor the mountain slope in real time and warn pedestrians on the road when the slope is abnormal, thereby improving the safety of the slope.

[0074] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0075] The embodiment of the present invention provides a specific implementation of a highway slope protection device, see Figure 1 as well as Figure 4 The slope protection device of the highway specifically includes the following contents:

[0076] The slope protection mechanism 6 is arranged on the bottom slope 2 of the mountain 1 on both sides of the highway 3;

[0077] The mountain protection mechanism 8 is arranged at the upper end of the mountain slope and is located above the slope protection mechanism 6; a preset angle with the vertex facing downward is formed between the mountain protection mechanism 8 and the mountain 1, and a retractable opening is formed between the bottom of the mountain protection mechanism 6 and the mountain 1;

[0078] It can be understood that when foreign objects fall from the top of the mountain 1, the V-shaped structure of the mountain protection mechanism 8 can effectively intercept them (conveniently catching foreign objects falling from the top of the mountain 1). When there are too many foreign objects (the weight exceeds the interception threshold of the telescopic opening), the foreign objects can fall from the telescopic opening and slowly slide into the road surface along the slope protection mechanism 6. It will not cause harm to vehicles and pedestrians on the highway 3, nor will it cause damage to the mountain protection mechanism 8 due to too many foreign objects. Specifically, when a foreign object falls from the top of the mountain 1, the foreign object falls between the wire mesh 82 and the mountain 1 under the action of the wire mesh 82, and then slides down along the wire mesh 82. The lower end of the wire mesh 82 is deformed by gravity. At the same time, the lower end of the wire mesh 82 pulls the sliding rod 83 to slide outward along the sliding sleeve 84, and the spring 85 is compressed to open the opening between the lower end of the wire mesh 82 and the mountain 1, so that the foreign object slides along the concrete layer 61, thereby preventing the foreign object from falling directly from a high altitude onto the highway 3.

[0079] The early warning mechanism 9 is used to monitor the humidity of the mountain 1 in real time, and issue an early warning when the humidity of the mountain 1 exceeds a preset threshold.

[0080] See also Figure 3 The early warning agency 9 detects the humidity of the mountain 1 in real time and sends the detected data to the PLC controller 93. The PLC controller 93 integrates and judges the received data. When the humidity of the mountain 1 is greater than the value set inside the PLC controller 93, it means that there is serious water seepage inside the mountain 1 and landslides may occur. At this time, the PLC controller 93 controls the alarm 94 to work, and the alarm 94 sounds an alarm to remind pedestrians on the highway 3 that there is a risk of landslide on the road ahead.
