Description

Technical Field

[0001] The present invention relates to the technical field of slope engineering, and more specifically, to an anchoring support structure for slope engineering. Background Art

[0002] Slope engineering refers to the engineering of reinforcing and protecting slopes. It is mainly used in mountainous areas, hilly areas, river banks, lake banks and other sloping terrains. The main purpose of slope engineering is to improve the stability of slopes and prevent natural disasters such as landslides and collapses, thereby protecting people's lives and property. In actual engineering, slope engineering often intersects with multiple disciplines such as civil engineering, geological engineering, and environmental engineering, and needs to comprehensively consider geological conditions, environmental factors, engineering requirements and other factors.

[0003] According to the patent document: CN109469076A, a deformable slope anchoring structure disclosed belongs to the field of slope support engineering, and is used to solve the problem that the bending resistance of steel pipe piles is weak, resulting in limited reinforcement effect on the slope, easy bending and deformation of steel pipe piles, and even complete failure of the anchoring structure. The present invention provides anchors and connectors, connects the steel pipe piles to the anchors through the connectors, and provides tensile support for the steel pipe piles through the anchoring effect of the anchors; thereby, one end of each steel pipe pile inserted into the slope can be connected to the stable bedrock, and the end of the steel pipe pile passing through the slope surface is connected to the anchor through the connector, so that the bending resistance of the steel pipe pile can be effectively improved, thereby effectively controlling the further deformation of the slope.

[0004] In the process of slope reinforcement, engineers usually take a common method, which is to insert anchor rods into the inner wall of pre-drilled holes. Then, they will use concrete to pour to achieve the purpose of slope reinforcement. This method is widely used in practice because it can effectively improve the stability of the slope. However, there are some problems in the traditional anchor reinforcement technology that cannot be ignored. For example, the anchor rods may become loose due to various reasons, which will directly affect the stability of the reinforced structure. In addition, concrete is prone to cracking during use, which not only affects the reinforcement effect, but also may bring safety hazards. Therefore, although this method is widely used in slope reinforcement, its problems cannot be ignored, and technological innovation is needed to further improve the reinforcement effect.

The inner sides of the two inner plates 3214 are fixedly connected to the semicircular connecting plates 3215. The inner sides of the two semicircular connecting plates 3215 are provided with threads.

[0035] When reinforcing the slope, first insert the anchor rod 1 into the hole preset in the slope, then insert the inner rod body 21 into the inner wall of the anchor rod body 11, and further insert the anchor rod 1 into the soil behind the hole through the inner rod plug 23, and then continue to insert the plug body 31 into the inner wall of the inner rod body 21;

[0036] When the insertion rod body 31 is fully inserted into the inner wall of the inner rod body 21, the two sides of the rear side of the reinforcing plate 321 press the two pulleys 18 to rotate the two pressure rods 17, and the rotation of the two pressure rods 17 drives the two positioning rods 19 to slide backward on the inner walls of the two slide slot blocks 15. At this time, the two springs 112 are compressed, and the two positioning rods 19 slide backward to drive the two positioning rod plugs 111 to move backward until the two positioning rod plugs 111 are fully inserted into the soil on the slope surface to initially fix the overall anchor rod 1;

[0037] The push plate 325 is then pushed to drive the outer plug rod 311 to push the inner wall of the inner rod body 21 to the rear side. When the push plate 325 is in contact with the reinforcing plate 321, the outer plug rod 311 continues to move backward on the outer wall of the inner plug rod 312. The movement of the outer plug rod 311 drives the front hinge shaft 313 to move backward. The movement of the front hinge shaft 313 drives the hinge shaft push rod 314 to push the expansion plate 315 on the inner wall of the outer plug rod 311 to open outward. The expansion plate 315, through the fixed The position slot 24 is expanded and embedded in the soil to improve the overall stability. At this time, the anchor rod 1 is embedded in the soil through the positioning rod plug 111 and the multiple expansion plates 315, thereby completing the deep fixation of the slope. After the push plate 325 and the reinforcement plate 321 are fitted, they can be inserted into the soil on the surface of the slope again through the second insertion hole 3216 and the insertion hole 322 by rivets or threaded nails, while fixing the push plate 325 and the reinforcement plate 321, the overall stability is increased again.

[0038] The rotation of the second rotating rod 328 further pushes the push block 329 to move outward, and the movement of the push block 329 causes the sliding block 3210 to move on the inner side of the two rotating rods 3211 and push the two rotating rods 3211 and the arc rotating rod 3212 to rotate around the axial rod 3213. The rotation of the arc rotating rod 3212 causes the two inner retracting plates 3214 to slide inward until the two semicircular connecting plates 3215 fit together. Since the inner walls of the two semicircular connecting plates 3215 are provided with threads, other reinforcements that need to be connected, such as cross bars, can be connected through the two semicircular connecting plates 3215. While connecting other components, the positions of the two semicircular connecting plates 3215 are further stabilized, thereby strengthening the fixing effect of the anchor rod 1 on the slope.

[0039] Working principle of the present invention: When reinforcing a slope, first insert the anchor rod 1 into the preset hole of the slope, then insert the inner rod body 21 into the inner wall of the anchor rod body 11, and further insert the anchor rod 1 into the soil at the rear side of the hole through the inner rod plug 23, and then continue to insert the insertion rod body 31 into the inner wall of the inner rod body 21. When the insertion rod body 31 is completely inserted into the inner wall of the inner rod body 21, the two sides of the rear side of the reinforcement plate 321 press the two pulleys 18 to rotate the two pressure rods 17, and the rotation of the two pressure rods 17 drives the two positioning rods 19 to move backward on the inner wall of the two slide blocks 15. When the two springs 112 are compressed, the two positioning rods 19 slide backwards, driving the two positioning rod plugs 111 to move backwards, until the two positioning rod plugs 111 are fully inserted into the soil on the slope surface to initially fix the overall anchor rod 1. When the insertion rod body 31 is fully inserted into the inner wall of the inner rod body 21, the two sides of the rear side of the reinforcement plate 321 press the two pulleys 18 to rotate the two pressure rods 17. The rotation of the two pressure rods 17 drives the two positioning rods 19 to slide backwards on the inner walls of the two slide groove blocks 15. At this time, the two springs 112 are compressed. The two positioning rods 19 slide backward and drive the two positioning rod plugs 111 to move backward until the two positioning rod plugs 111 are completely inserted into the soil on the slope surface to initially fix the integral anchor rod 1. At the same time, the push of the push plate 325 also causes the two sets of push plate sliders 326 to slide backward on the inner walls of the two side slide groove rods 323. The sliding of the push plate sliders 326 drives the second rotating rod 328 to rotate. The rotation of the second rotating rod 328 further drives the push block 329 to move outward. The movement of the push block 329 causes the sliding block 3210 to slide inside the two rotating rods 3211. Move sideways and push the two rotating rods 3211 and the arc-shaped rotating rod 3212 to rotate with the axial rod 3213 as the axis. The rotation of the arc-shaped rotating rod 3212 causes the two inner retracting plates 3214 to slide inward until the two semicircular connecting plates 3215 fit together. Since the inner walls of the two semicircular connecting plates 3215 are provided with threads, other required reinforcements, such as cross bars, can be connected through the two semicircular connecting plates 3215. While connecting other components, the positions of the two semicircular connecting plates 3215 are further stabilized, thereby strengthening the fixing effect of the anchor rod 1 on the slope.
