Description

Technical Field

[0001] This utility model relates to the technical field of slope protection, and in particular to an anchoring structure for highway slope protection netting. Background Technology

[0002] In highway construction, slope stability is of paramount importance. To prevent geological disasters such as rockfalls and landslides, flexible protective netting systems are often used for protection. Anchor bolts are the foundation of the protective netting system, which anchor the protective netting inside the slope to bear and transfer the load.

[0003] Existing highway slope protection net anchoring structures, such as the slope protection structure based on active monitoring disclosed in utility model patent application number 202222033871.6, mainly include a protective net wrapped around the slope surface by an anchoring mechanism. The anchoring mechanism includes several prefabricated holes distributed on the slope surface for anchor rods to be inserted. The ends of the anchor rods have pull rings, which are connected to horizontal and vertical support ropes to divide the slope surface into several areas. In use, according to the specific conditions such as the slope structure, soil layers, and geographical location, tension sensors are connected to the anchor rods at different locations on the slope surface to form preset areas that sense changes in tension.

[0004] However, the slope soil is relatively loose, and most of the existing anchoring structures have poor fixing effect. When vehicles pass by, the vibration of the anchor rods can easily cause fatigue damage or fall off. Moreover, most of the existing anchoring structures can only fix the protective netting at points, with a small fixing range. A large number of anchoring structures are required, which makes construction troublesome. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a highway slope protection net anchoring structure that not only increases the fixed area of ​​a single anchoring structure by extending the structure, reducing the use of anchoring structures and facilitating construction, but also enhances the stability of the device by using an expansion mechanism to avoid structural fatigue damage or detachment caused by vibration.

[0006] This utility model discloses an anchoring structure for a highway slope protection net, including an anchor bolt mechanism; it also includes a driving structure, two sets of expansion structures, three sets of extension structures, and three sets of pressing mechanisms. The driving structure is installed on the anchor bolt mechanism and drives the two sets of expansion structures to expand. The two sets of expansion structures are installed on the driving structure and enhance the stability of the anchor bolt mechanism. The three sets of extension structures are installed on the anchor bolt mechanism and increase the fixing range. The three sets of pressing mechanisms are respectively installed on the three sets of extension structures and ensure fixing pressure. After the workers lay the protection net on the slope, they wed the anchor bolt mechanism into the slope, rotate the driving structure, and the driving structure supports the two sets of expansion structures, enhancing the stability of the anchor bolt mechanism and preventing it from falling off. The three sets of pressing mechanisms push the three sets of extension structures to fix the protection net, increasing the fixing area and reducing the use of anchoring structures.

[0007] Preferably, the anchor bolt mechanism includes a sleeve, a pressing plate, a top plate, a threaded section, and a guide head. The sleeve has a square groove inside. The pressing plate is installed on the sleeve, the top plate is installed on the top of the sleeve, the top of the threaded section is connected to the bottom of the sleeve, and the top of the guide head is connected to the bottom of the threaded section. Workers tap the top plate to wedge the sleeve into the slope. The guide head reduces the resistance when wedging into the soil, and the threaded section increases the friction between the sleeve and the soil to prevent it from falling off. The pressing plate presses down on the protective netting.

[0008] Preferably, the drive structure includes a knob, a lead screw, two sets of helical gears, a slider, and a telescopic sealing sleeve. The knob is rotatably mounted on the sleeve, and the lead screw is rotatably mounted in the square groove of the sleeve. The two sets of helical gears are respectively mounted on the knob and the lead screw and mesh to drive the transmission. The slider is slidably mounted in the square groove of the sleeve and is connected to the lead screw through threaded transmission. The telescopic sealing sleeve is fitted onto the lead screw. When the operator rotates the knob, the knob drives the lead screw to rotate through the meshing of the two sets of helical gears. The lead screw drives the slider to slide downward along the square groove. The telescopic sealing sleeve prevents soil from entering and affecting the transmission of the lead screw and slider.

[0009] Preferably, the expansion structure includes a first connecting shaft, a second connecting shaft, two sets of support plates, and a hinge. The first connecting shaft is mounted on the sleeve, the second connecting shaft is mounted on the slider, and the two sets of support plates are respectively mounted on the first and second connecting shafts. The hinge is installed between the two sets of support plates. The slider drives the two sets of second connecting shafts to descend, and the second connecting shafts descend closer to the first connecting shaft, thereby causing the two sets of support plates to fold outward and bulge, enhancing the stability of the sleeve.

[0010] Preferably, the support plate surface is engraved with a diamond pattern; by setting the diamond pattern, the resistance to sliding is increased, and part of the interface friction is transformed into mechanical interlocking, thereby reducing the impact of vibration on the structure.

[0011] Preferably, the extension structure includes a third connecting shaft, an extension plate, and multiple sets of pressing blocks. The third connecting shaft is rotatably mounted on the pressing plate, the extension plate is mounted on the third connecting shaft, and the multiple sets of pressing blocks are all mounted on the extension plate. The pressing mechanism pushes the extension plate to press the protective net, and the pressing area is increased by setting multiple sets of pressing blocks.

[0012] Preferably, the pressing mechanism includes a connecting plate, two sets of springs, and two sets of protective sleeves. The connecting plate is installed on the top plate, the two sets of springs are connected and installed between the connecting plate and the extension plate, and the two sets of protective sleeves are respectively fitted onto the two sets of springs. The two sets of springs push the extension plate to rotate, so that the multiple sets of pressing cross blocks are close to the protective net, ensuring the pressing and fixing effect on the protective net. By setting the protective sleeves along the service life of the springs, the springs are prevented from rusting and failing.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: After the workers lay the protective net on the slope, they wedge the anchor mechanism into the slope, rotate the drive structure, and the drive structure supports the two sets of expansion structures, which enhances the stability of the anchor mechanism and prevents it from falling off. The three sets of pressing mechanisms push the three sets of extension structures to fix the protective net, increase the fixed area, and reduce the use of anchoring structures.
