Description

Technical Field

[0001] The invention relates to the technical field of slope reinforcement, and in particular to a roadbed rock slope stability reinforcement structure and method. Background Art

[0002] The roadbed rock slope refers to the roadbed slope whose entire slope is composed of rock mass. This type of slope can be divided into hard rock slope, soft rock slope and weathered rock slope according to the strength of the rock mass. The rock slope plays an important role in the roadbed project, and its stability has a direct impact on the overall stability of the roadbed.

[0003] The characteristics of rock slopes are that they are made of hard rock, so they can withstand greater pressure and loads. At the same time, due to the characteristics of their rock, rock slopes show good durability and stability in long-term use. However, the maintenance and repair costs of rock slopes can be relatively high, especially when large-scale rock excavation or reinforcement work is required.

[0004] For example, the application number 202321894420.X provides basic reinforcement of the edge of the slope by setting a reinforcement bracket to provide support for the internal reinforcement of the slope; further reinforces the middle of the slope by setting a fixed screw to ensure the stability of the slope; prevents a large amount of water from entering the soil of the slope by setting a waterproof layer to avoid landslides, ensure stability and the safety of the surrounding environment; and further strengthens the stability of the slope by setting a fixed layer, while improving the beauty of the slope. However, the device still has certain defects;

[0005] When reinforcing the slope, multiple workers are needed to arrange and lay the fixed layer on the slope surface, which makes the laying difficult. At the same time, when the slope needs to be trimmed, it is not convenient to store the fixed layer.

[0006] Therefore, we proposed the roadbed rock slope stability reinforcement structure and method to solve the above problems. Summary of the invention

When the protective net is used, the protective net can be directly pulled out, thereby reducing the difficulty of installing the protective net.

The method for reinforcing the stability of a roadbed rock slope according to claim 1, characterized in that: The reinforcement method of the roadbed rock slope stability reinforcement structure specifically comprises the following steps: S1. Conducting a field test on the rock slope body (1), and processing a protective frame (2) of suitable size according to the position and size of the rock slope body (1), burying a drainage pipe (16) inside the left side of the rock slope body (1), and installing a filter screen (17) on the drainage pipe (16), installing the protective frame (2) on the left side of the rock slope body (1), and draining part of the water inside the rock slope body (1) through the drainage pipe (16), and guiding the water into the protective frame (2), and then draining it into the ditch through the drainage pipe (26) on the protective frame (2), thereby preventing the rock slope body (1) from collapsing due to excessive water inside the rock slope body (1), and the filter screen (17) can prevent mud residue from entering the protective frame (2) and making it inconvenient to clean; S2, pull the top plate (19) upward, the top plate (19) drives the protective plate (20) to move upward, at this time, the telescopic spring (18) is in a stretched state, and at the same time, the positioning strip (21) on the top plate (19) moves upward, and the positioning strip (21) can guide the top plate (19) and the protective plate (20) to move up and down more stably, so that the top plate (19) drives the protective plate (20) to move up and down more stably, and at this time, the connecting shaft (22) is rotated, and the connecting shaft (22) drives the limiting plate (23) to rotate in the opposite direction to the positioning strip (21), and when the limiting plate (23) rotates to be located directly below the positioning strip (21), the connecting shaft (22) and the top plate (19) are released, and at this time, the positioning strip (21) below the top plate (19) abuts against the limiting plate (23), thereby limiting the top plate (19), thereby limiting the protective plate (20) on the top plate (19); S3, pulling out the rolled-up protective net (4) on the rotating shaft mechanism (3), so that the upper surface of the protective net (4) can abut against the guide roller (25) when being pulled, and guiding the protective net (4) through the guide roller (25) until one end of the protective net (4) is pulled to the end of the inclined surface of the rock slope body (1), and then burying the first fixing rod (7) into the interior of the rock slope body (1) through the first fixing pressure plate (5) and the second fixing pressure plate (6), thereby completing the pressing and fixing of the protective net (4) through the first fixing pressure plate (5) and the second fixing pressure plate (6); S4, pull the first steel wire rope (8) and the second steel wire rope (9) on the first fixed pressure plate (5) and the second fixed pressure plate (6) closer to each other, so that the first connecting block (10) and the second connecting block (11) on the first steel wire rope (8) and the second steel wire rope (9) are closer to each other, so that the protrusion (13) on the first connecting block (10) is engaged with the built-in groove (12) on the second connecting block (11), and then install the second fixing rod (15) on the first connecting block (10) and the second connecting block (11), and the second fixing rod (15) is installed on the first connecting block (10) and the second connecting block (11). The fixed rod (15) can pass through the positioning hole (14) on the protrusion (13), so that the second fixed rod (15) is buried inside the rock slope body (1) after passing through the first connecting block (10) and the second connecting block (11), so that the protection net (4) is pressed and fixed by the first steel wire rope (8) and the second steel wire rope (9), the first connecting block (10) and the second connecting block (11), thereby improving the fit between the protection net (4) and the surface of the rock slope body (1), thereby providing more stable protection for the rock slope body (1); S5. Finally, the top plate (19) is pulled upward, and the top plate (19) drives the positioning bar (21) to move upward away from the limiting plate (23), and then the connecting shaft (22) is rotated to reset the limiting plate (23), and then the top plate (19) is released, and the top plate (19) moves downward and resets under the action of the rebound force of the telescopic spring (18), thereby driving the protective plate (20) to move downward, so that the protective plate (20) closes the rectangular groove (24).
