Description

Technical Field

[0001] This utility model relates to the field of highway technology, and in particular to a temporary retaining structure for the roadbed of a longitudinally elevated section of a highway. Background Technology

[0002] With the continuous improvement of transportation networks, the number of highway reconstruction and expansion projects is increasing. During the construction of longitudinal elevation sections, reliable temporary retaining structures are required due to the connection between the old and new roadbeds and the stability requirements during construction. Traditional temporary retaining structures have many shortcomings: poor stability of the fill pile, great influence of rainwater erosion, easy collapse, and easy rot and damage in humid environments. When carrying out longitudinal elevation construction of highways on soft soil foundations, these traditional retaining structures cannot effectively resist the deformation of the foundation and the lateral pressure of the soil, and cannot meet the engineering requirements.

[0003] A search revealed Chinese Patent Publication No. CN206721593U, which discloses a protective structure for the reconstruction of elevated highway subgrades. The structure includes a subgrade layer, a raised layer at the top of the subgrade layer, and protective plates on both the left and right sides of both the subgrade layer and the raised layer. Bearing seats are located on the upper and lower left sides of the left protective plate and the upper and lower right sides of the right protective plate. Support rods are connected to the left side of the left bearing seat and the right side of the right bearing seat. A stud is fitted onto the outer wall of the other end of each support rod. A strong support spring connects the open end to the bearing seat. Through the coordinated arrangement of the protective plate, bearing seat, support rod, stud, strong support spring, support block, vertical baffle, mounting base, inverted buckle, elastic steel plate and stop block, real-time protection can be provided for the raised floor. The protection effect is good, it is not easy to loosen, and it can be automatically adjusted, making it highly practical. However, this utility model does not take into account the situation where the equipment may have different sizes during operation. If the height and width of the equipment cannot be adjusted, the adaptability of the equipment will be weak, reducing the practicality and work efficiency of the equipment. Utility Model Content

[0029] 1. In this utility model, to adjust the height of the equipment, the telescopic rod is activated to push the first column upward along the inner wall of the hollow column. When adjusting the width, the second limiting ring is rotated to dislodge the outer wall of the second limiting column, and the second fixing block is pulled out to remove the second limiting column. The longitudinal column slides out from the inner wall of the hollow column. After adjusting to the required width, the second limiting column is reinserted and the second limiting ring is tightened. This allows for the adjustment of the equipment height and width, adapting to more work scenarios and improving the practicality and work efficiency of the equipment.

[0030] 2. In this utility model, when adjusting the length of the equipment, rotate the limiting ring one so that it rotates out from the outer wall of the limiting post one, pull the fixing block one together with the limiting post one out from the hollow post two, the transverse post loses its restriction and can move to both sides. After reaching the required length, reinsert the limiting post one and tighten the limiting ring one, so as to realize the adjustment of the length of the equipment and prevent the need to replace the equipment due to the length problem, thus prolonging the working time.

To adjust the width of the equipment, rotate the limiting ring 10, causing the limiting ring 10 to rotate out from the outer wall of the limiting column 9. Then pull the fixing block 11, which will cause the limiting column 9 to be pulled out from the inside of the hollow column 7. Then pull the longitudinal column 6 to both sides, and the longitudinal column 6 will gradually slide out from the inner wall of the hollow column 7. After adjusting to the specified width, insert the limiting column 9 and tighten the limiting ring 10. This will allow you to adjust the height and width of the equipment, adapting to more work scenarios and improving the practicality and work efficiency of the equipment.

[0048] When the length of the equipment needs to be adjusted, rotate the limiting ring 205 so that it rotates out of the outer wall of the limiting post 204. Then pull the fixing block 206, which will cause the limiting post 204 to be pulled out of the hollow post 202. As a result, the transverse post 201 is no longer restricted and is pulled to both sides. Under the action of the pulling force, the transverse post 201 will move to both sides along the inner wall of the hollow post 202. After reaching the specified length, insert the limiting post 204 and tighten the limiting ring 205. This will allow the length of the equipment to be adjusted, preventing the need to replace the equipment due to length issues and extending the working time.
