Description

Technical Field

[0001] The utility model relates to the technical field of urban roads, in particular to a non-excavation reinforcement structure for collapsible loess roadbed of an urban road. Background Art

[0002] Collapsible loess has the characteristics of porous structure and large internal pores. When it comes into contact with water, its internal structure is easily destroyed and its strength is reduced, causing collapse and deformation. Collapsible loess is a bad geological condition. Roads built in collapsible loess areas are prone to roadbed subsidence and deformation after being soaked in water, which seriously affects the quality and service life of the road.

[0003] For example, a trenchless reinforcement structure for collapsible loess roadbed on an urban road with authorization announcement number "CN219951578U" has solved the problem of existing trenchless reinforcement structures for collapsible loess roadbeds on urban roads. Chemical grouting can well fill and reinforce local defects such as collapsible loess collapses and holes. The above-mentioned structure is improved by adding cement, water reducers, retarders, etc., and is used for anti-seepage curtain construction. An anti-seepage curtain is formed under the curb to separate the green belt from the carriageway, eliminating the infiltration of greening irrigation water into the roadbed from the source. Considering the existing trenchless reinforcement structure for collapsible loess roadbed on urban roads, it is necessary to improve the addition of cement, water reducers, retarders, etc., and the internal structure of the collapsible loess road needs to be changed, which makes it more difficult to construct the urban road again, resulting in the inability to achieve the effect of internal trenchless reinforcement. Summary of the invention

[0004] The utility model aims to solve the problems existing in the above-mentioned prior art and provides a trenchless reinforcement structure for collapsible loess roadbed of urban roads, which again increases the difficulty in the construction of urban roads and makes it impossible to achieve the effect of internal trenchless reinforcement.

[0005] The utility model adopts a technical solution to solve its technical problems: a non-excavation reinforcement structure for collapsible loess roadbed of an urban road, comprising a loess ground surface and a curbstone, a reinforcement mechanism being provided at the upper end of the loess ground surface, the reinforcement mechanism comprising a reinforcement plate, the lower end of the reinforcement plate being in contact with the loess ground surface, the lower end of the reinforcement plate being fixedly connected to a powder spray column reinforcement body, a groove being installed on the surface of the reinforcement plate, the outer wall of the groove being connected to a long groove, a long groove being installed on the surface of the reinforcement plate, and the outer wall of the reinforcement plate being fixedly connected to a rubber strip.

[0006] For further improvement, a supporting mechanism is provided at the lower end of the curbstone, and the supporting mechanism includes an anti-seepage curtain, the upper end of the anti-seepage curtain is tightly pressed against the curbstone, the outer wall of the anti-seepage curtain is fixedly connected to the square bar, and the outer wall of the square bar is fixedly connected to the supporting block.

[0007] For further improvement, the surface of the reinforcement plate is provided with a lane wheel track line.

[0008] For further improvement, the lower end of the reinforcement plate is fixedly connected to the reinforcement rod, and the lower end of the reinforcement rod is fixedly connected to the trapezoidal bar.

[0009] For further improvement, the surface of the loess ground is fitted with the square frame, the inner wall of the square frame is pressed against the rubber strip, the lower end of the square frame is fixedly connected to the ground cone, and the outer wall of the ground cone is pressed against the loess ground of the square frame.

[0010] For further improvement, a text warning sign is installed on the upper end of the curb.

[0011] The beneficial effect of the utility model is as follows: the utility model places a square frame on the surface of the loess ground, inserts the ground cone at the lower end of the square frame into the ground, and sequentially inserts the powder spray column reinforcement body at the lower end of the reinforcement plate into the interior of the loess ground, until the rubber strip on the outer wall of the reinforcement plate is tightly pressed against the inner wall of the square frame, and the square frame, the reinforcement plate and the collapsible loess ground form buoyancy, thereby ensuring the stability of vehicles driving on the reinforcement plate, without the need to excavate the collapsible loess roadbed of the urban road, and achieving the effect of forming a complete road surface on the surface.

[0023] A supporting mechanism 4 is provided at the lower end of the curbstone 2. The contact area with the collapsible loess ground surface 1 is increased through the square bars 402 and the supporting blocks 403 on the anti-seepage curtain 401, so that the inner wall of the anti-seepage curtain 401 and the loess ground surface 1 can achieve a supporting effect.

[0026] Working Principle: Installation Phase:

[0027] According to the width between the loess ground 1 and the square frame 9, the square frame 9 is placed on the surface of the loess ground 1, and the ground cone 10 at the lower end of the square frame 9 is inserted into the ground, so that the ground cone 10 generates a supporting force for the upper end of the square frame 9 to ensure the stability of the square frame 9 without external force.
