A flexible support and reinforcement component for highway subgrade

Abstract

The invention belongs to the technical field of road construction, and discloses a flexible support and reinforcement assembly for road subgrades, including a fixing base, a fixing sleeve is arranged on the top of the fixing base, and a supporting component is movably installed inside the fixing sleeve. Both left and right ends of the fixing base are movably installed with fixing parts. In the present invention, by arranging the first bolt and the notch, when the first bolt is rotated into the foundation by rotating the second rotating block, the second bolt moves upward relative to the first bolt by rotating the third rotating block, and due to the second The movement of the bolt will drive the connecting rod to move upward, and then the connecting rod will drive the fixed rod to move upward, and because the other end of the fixed rod is movably connected to the notch, when the fixed rod moves upward, it will be in the action of the notch. The top of the fixing rod is inserted into the foundation around the first bolt, thereby improving the fixing strength of the device to the foundation.

Description

technical field [0001] The invention belongs to the technical field of road construction, in particular to a flexible support and reinforcement assembly for road subgrades. Background technique [0002] In the process of highway subgrade construction, due to the loose structure of the subgrade and slope protection filler in the natural state, the strength and stability are poor, and some road sections are on soft soil foundations, making it difficult for the road subgrade to meet the road traffic load and natural conditions. Requirements of environmental effects, this will inevitably require manual recompaction of the roadbed or slope protection, that is, necessary reinforcement treatment works, to ensure that the strength and stability indicators of the roadbed meet the design and specification requirements to maintain the stability of the roadbed and slope protection. [0003] In a roadbed slope protection device whose patent number is CN210127478U, the outer wall of the c...

Problems solved by technology

[0003] In a roadbed slope protection device whose patent number is CN210127478U, the outer wall of the concrete layer is plugged with a diagonal rod, which is perpendicular to the roadbed slope, and the diagonal rod plays the role of reinforcing the roadbed slope, and the outer wall of the diagonal rod is socketed There is a connecting plate, the outer wall of the concrete layer is attached with a slanted plate, the outer wall of the slanted plate is screwed with a screw rod, the bottom of the slanted plate is attached with a horizontal plate, the slanted plate is screwed with the horizontal plate and the inclined rod through the screw rod, and through The mutual cooperation of the inclined rod and the screw rod completes the reinforcement and protection of the roadbed slope, but the threaded connection of the screw rod and the inclined rod is easy to loose after long-term use, which reduces the fixing effect and the protective effect on the roadbed slope protection; the patent number is In CN206706784U, in a kind of highway embankment slope protection device, by setting the outer cylinder slope protection assembly and the inner cylinder slope protection assembly, there are many flexible gripping strips with different inclination angles and different lengths welded on the outer side of the outer cylinder of the outer cylinder slope protection assembly. Improve the fixing strength of the outer cylinder slope protection components; and after completing the fixing of the outer cylinder slope protection components, nest the inner slope protection components into the outer cylinder slope protection components to complete the fixing of the device; among them, although the flexible grab bar is combined with the concrete Finally, the fixing strength of the slope protection components of the outer cylinder can be improved, but due to its flexible nature and welding fixation, the fixing strength is limited and the fixing angle of the flexible grab strip cannot be adjusted, resulting in a general fixing effect
