Description

Technical Field

[0001] This utility model relates to the technical field of highway slope protection equipment, and in particular to a slope reinforcement device. Background Technology

[0002] Slope protection refers to the sides and embankments of highways. The support and protection of high highway slopes is a crucial aspect of road engineering, directly impacting the stability and safety of the road and its slopes. Its primary purpose is to prevent slopes or roadbeds from being eroded by continuous rainfall, earthquakes, or the impact of surrounding engineering projects, which could lead to landslides, collapses, spalling, and subsidence. Simultaneously, it enhances the ecological environment of the highway. By stabilizing the roadbed and absorbing natural forces such as rainfall, slope protection prevents erosion, landslides, and slope accumulation between the roadbed and steep slopes, thus ensuring the long-term safety of the highway. Furthermore, the construction of ecological vegetation along slopes can reduce environmental damage, protect ecological balance, improve environmental quality, optimize the traffic environment, and beautify highways.

[0003] Currently, existing slope protection reinforcement structures are constructed by building molds on the slope and pouring concrete into the molds for integral casting. The manual construction of molds is time-consuming and labor-intensive, and the integral concrete casting structure has poor stability. In the event of ground settlement, it will quickly break and collapse, and the slope debris will also sink, making the entire slope more susceptible to rainwater erosion. In addition, the existing precast slope protection reinforcement structures are expensive to manufacture and time-consuming and labor-intensive to assemble. In recent years, earthquakes have become more frequent and secondary disasters have increased. The existing slope protection reinforcement structures have weak earthquake resistance and are prone to safety hazards. Utility Model Content

[0004] This utility model provides a slope protection reinforcement device that solves the problems of traditional slope protection reinforcement structures, such as high construction difficulty, poor stability, weak seismic resistance, high manufacturing cost, and time-consuming and labor-intensive assembly.

[0005] This utility model provides a slope protection and reinforcement device, including a slope body. An inclined metal protective net is laid on the sloping surface of the slope body. The upper end of the metal protective net extends upward to the top of the slope body and is fixed to the top of the slope body by a pressure plate. A sand and gravel enclosure structure is set on the metal protective net. The sand and gravel enclosure structure includes multiple enclosure frames. Adjacent enclosure frames on the sloping side of the slope body are connected by connectors. A baffle is set at the foot of the slope body. The baffle is connected to the pressure plate at the top of the slope body by multiple steel wire ropes.

[0006] In the above technical solution, each of the enclosure frames is a regular hexagon, and the enclosure frames are arranged in a row on the slope surface of the main body of the slope. Each enclosure frame includes six enclosure frame plates and positioning pins. The six enclosure frame plates are connected end to end by the positioning pins.

[0007] In the above technical solution, the connecting member is a U-shaped plate, and the fence frame plates of two adjacent fence frames are snapped together by the U-shaped plate, and sand and gravel are set inside each fence frame.

[0008] In the above technical solution, the fence frame plate is further made of ultra-high performance concrete.

[0009] In the above technical solution, the pressure plate is further fixed to the top of the slope body by multiple anchor rods.

[0010] In the above technical solution, the baffle is further defined as an L-shaped plate, which includes a fixing plate and a limiting plate. The fixing plate is disposed on the slope surface of the main body of the slope. The lower end of the fixing plate is vertically connected to the limiting plate. The lower end of the wire rope is connected to the lug provided on the limiting plate. The upper end of the wire rope is fixedly connected to the pre-set lifting eye bolt on the pressure plate.

[0011] As can be seen from the above technical solutions, this utility model provides a slope protection and reinforcement device.

[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0030] Example 1:

[0031] See Figure 1-6A slope protection and reinforcement device includes a slope body 1. A layer of metal protective netting 2 is laid on the slope surface of the slope body 1 and adhered to the slope surface. The surface of the metal protective netting 2 is covered with mesh to intercept the sand and gravel laid on the slope surface of the slope body 1, preventing the sand and gravel from passing through the metal protective netting 2 and keeping the sand and gravel on the slope surface of the slope body 1. This protects the sand and soil inside the slope body 1 and prevents rainwater from directly contacting the soil layer and causing erosion of the slope body 1. The metal protective netting 2 is spliced ​​from multiple individual protective nets. The upper end of the metal protective netting 2 extends upward to the top of the slope body 1 and stretches into a horizontal state. Then, it is horizontally pressed onto the metal protective netting 2 by a pressure plate 3, and fixed by an anchor rod 7 penetrating the pressure plate 3 and inserting the metal protective netting 2 into the interior of the slope body 1. A sand and gravel enclosure structure 4 is set on the upper surface of the metal protective netting 2. The sand and gravel enclosure structure 4 includes multiple enclosure frames 41. The shape of the enclosure frames 41 can be a regular polygon, such as a regular square or a regular hexagon. The use of a regular polygon structure has good stability and facilitates the enclosure of each frame. The assembly of the frame 41 reduces the labor intensity of construction workers. Simultaneously, it clarifies the force direction of the frame 41. Adjacent frames 41 on the slope of the main body 1 are fixedly connected by connectors 42. Since each frame 41 is prone to moving downwards along the slope of the main body 1, the connectors 42 securely connect adjacent frames 41 together, allowing the frames 41 to enclose and stabilize the sand and gravel, preventing downward movement. A baffle is installed at the toe of the slope of the main body 1. 5. The baffle 5 is fixedly connected to the pressure plate 3 on the top of the slope body 1 by multiple steel wire ropes 6. By installing metal protective net 2 and enclosure frame 41 on the slope surface of the slope body 1, and filling the enclosure frame 41 with sand and gravel, the slope soil of the slope body 1 is protected by filling with sand and gravel, preventing rainwater from directly impacting the slope soil and causing soil erosion. The metal protective net 2 and enclosure frame 41 are easy to install, the labor intensity of construction personnel is low, and the sand and gravel enclosure structure 4 has high stability, strong earthquake resistance, and low production cost.

[0032] As a preferred embodiment of this example, see Figure 4 , 56. Each enclosure frame 41 is a regular hexagon, and the enclosure frames 41 are arranged in a row on the slope surface of the main body of the slope 1. Each enclosure frame 41 includes six enclosure frame plates 411 and positioning pins 412. The six enclosure frame plates 411 are connected end to end by the positioning pins 412. Specifically, the enclosure frame plates 411 of the enclosure frame 41 are long strips. The thickness of the two ends of the enclosure frame plates 411 is processed to half the overall thickness, and hinge holes are processed at both ends of the enclosure frame plates 411. The corresponding hinge holes of two pre-assembled enclosure frame plates 411 are hinged together by the positioning pins 412. The assembly is convenient. It can be assembled in the prefabrication workshop and then transported to the installation site for installation, or individual enclosure frame plates 411 can be transported to the installation site for assembly. The installation is convenient and also facilitates later maintenance and replacement.

[0033] In this embodiment, see Figure 5 The connector 42 is an inverted U-shaped plate, which is formed by bending a steel plate into a U-shape. The fence frame plates 411 of two adjacent fence frames 41 are connected together by the U-shaped plate to prevent the fence frame plates 411 of two adjacent fence frames 41 from separating. The U-shaped plate makes it easy and fast to assemble the fence frame 41, allowing construction workers to work quickly. It is not affected by the season and can be constructed all year round. Each fence frame 41 is filled with sand and gravel to protect the slope soil of the main slope 1 and prevent rainwater from directly impacting the slope soil and causing soil erosion. Each enclosure frame 41 encloses sand and gravel, forming an independent area for the sand and gravel within each frame 41. This facilitates the observation of the amount of sand and gravel in each area. When a certain area of ​​the ground subsides, the amount of sand and gravel enclosed in the corresponding enclosure frame 41 will decrease. Since sand can pass through the mesh covering the surface of the metal protective net 2 and sink with the subsided soil, the pebbles in the sand and gravel will be trapped inside the enclosure frame 41. However, the overall amount of sand and gravel inside the enclosure frame 41 will decrease, and the height will be reduced, making it easier to observe through detection equipment and carry out further maintenance in a timely manner.

[0034] In this embodiment, see Figure 3 The fence frame plate 411 is made of ultra-high performance concrete (UHPC). UHPC has extremely high mechanical properties, excellent durability, and resistance to blasting and impact. Compared with ordinary concrete, it has made a qualitative breakthrough in various properties and has broad application prospects in fields such as long-span bridges, super high-rise buildings, marine engineering, and military protection engineering. The fence frame 411, which is integrally cast with UHPC, has high strength and can prevent damage during slope settlement or rain erosion. The fence frame plate 411 is not easy to break and can fix the position of the sand and gravel inside the fence frame 41. It covers the slope of the main body 1 and provides external protection and reinforcement to the slope.

[0035] In this embodiment, see Figure 2 , 3 The baffle 5 is an L-shaped plate, which includes a fixing plate 51 and a limiting plate 52. The fixing plate 51 is fixed to the slope surface of the slope body 1. The fixing plate 51 has a pre-drilled positioning hole. An anchor rod passes through the positioning hole and is inserted into the slope body 1 to fix the fixing plate 51 to the slope body 1. The lower end of the fixing plate 51 is fixedly connected to the limiting plate 52 vertically. The fixing plate 51 is made of concrete. The lower end of the wire rope 6 is connected to the ear seat 53 fixedly installed on the limiting plate 52. The ear seat 53 is partially cast inside the limiting plate 52 for fixation. The upper end of the wire rope 6 is fixedly connected to the pre-set lifting eye bolt 54 on the pressure plate 3. The lifting eye bolt 54 is partially cast inside the pressure plate 3 for fixation.

[0036] As can be seen from the above technical solution, during use, firstly, the slope surface of the main body of the slope 1 is leveled, and then construction is carried out from the bottom of the slope body 1 upwards. The baffle 5 is placed at the foot of the slope body 1, and the fixing plate 51 is fixed obliquely on the slope surface of the main body of the slope 1. The lower end of the fixing plate 51 is vertically connected to the limiting plate 52. Then, a metal protective net 2 is laid on the slope surface of the main body of the slope 1. The upper end of the metal protective net 2 extends upwards to the top of the main body of the slope 1 and stretches into a horizontal state. Then, the pressure plate 3 is pressed horizontally on the metal protective net 2 and fixed to the top of the main body of the slope 1. The upper surface of the metal protective net 2 is equipped with a regular hexagonal enclosure frame 41 in an array. The six enclosure frame plates 411 of the regular hexagonal enclosure frame 41 are connected end to end by the positioning pins 412. During installation, ensure that the... The top and bottom frame plates 411 of the hexagonal enclosure frame 41 are kept horizontal. The frame plates 411 of two adjacent enclosure frames 41 are snapped together by U-shaped plates. The lower end of the wire rope 6 is connected to the ear seat 53 installed on the limiting plate 52, and the upper end of the wire rope 6 is fixedly connected to the pre-set lifting eye bolt 54 on the pressure plate 3. Then, the enclosure frame 41 at the top of the slope body 1 is tied and fixed to the wire rope seat fixed on the pressure plate 3 by wire, so that the enclosure frames 41 on the slope surface of the slope body 1 are fixed together longitudinally, and the whole is fixed on the slope surface of the slope body 1 by connecting and fixing it to the pressure plate 3. Each enclosure frame 41 is fixedly connected to the wire rope 6 by wire rope 6 to prevent the enclosure frame 41 from sinking during the ground settlement process.
