Description

Technical Field

[0001] This application relates to the technical field of subgrade reinforcement, and particularly relates to a subgrade reinforcement structure. Background Art

[0002] The subgrade is the foundation of the track or road surface, and is a geotechnical structure formed by excavation or filling. The main function of the subgrade is to provide necessary conditions for the laying of the track or road surface and the operation of trains or vehicles, and to bear the static and dynamic loads of the track and rolling stock or the road surface and traffic loads, and at the same time transfer and disperse the loads deep into the foundation. In the longitudinal section, the subgrade must ensure the elevation required by the line: in the plane, the subgrade is connected with bridges and tunnels to form a complete and through line. In civil engineering, the subgrade occupies an important position in terms of construction quantity, floor area and investment. The subgrade body includes embankments filled with natural soil and rock and cuttings excavated in natural strata. It directly supports the track and bears the train loads passing through the track, and is the main body of the subgrade. According to different geological conditions and filling materials, the subgrade body can be further divided into six basic forms: embankment, cutting, half-embankment, half-cutting, half-embankment and half-cutting, and non-fill and non-excavation subgrade.

[0003] A patent document with the publication number of CN219342718U discloses a subgrade reinforcement structure, belonging to the field of subgrade reinforcement construction. The subgrade is successively paved with an asphalt layer, a cement mortar layer, a concrete layer, a thick sand and gravel layer and a paving base layer from top to bottom. Loose soil is piled up on the left and right sides of the subgrade, and a pressing module for locking it on the side of the subgrade is provided on the loose soil. The pressing module includes a soil-locking pressing plate attached to the outside of the loose soil. The lower end of the soil-locking pressing plate is fixedly connected to a horizontal plate flush with the ground. A number of through holes are evenly opened on the horizontal plate, and hook-shaped ground nails are embedded in the through holes. A barb-structured embedding plate is fixedly connected to the middle of the side of the soil-locking pressing plate close to the loose soil, and the embedding plate is embedded into the loose soil. Through a subgrade reinforcement structure designed by the utility model, the side loose soil of the subgrade is effectively protected in the form of a sticker plate, avoiding the corrosion of the subgrade caused by soil erosion, increasing the service life of the subgrade, and having available value in the field of subgrade construction.

[0004] However, in actual application, in the above-mentioned patent document, when using the soil-locking pressing plate to squeeze and block the loose soil on the side of the subgrade, due to the hook-shaped ground nails fixing the soil-locking pressing plate, over time, the moisture in the soil will cause them to gradually rust and break, and finally the stability of the soil-locking pressing plate is reduced and cannot meet the use requirements. Therefore, it is not conducive to popularization and use.

[0005] Therefore, those skilled in the art have provided a subgrade reinforcement structure to solve the problems raised in the above background art. Summary of the Utility Model

[0018] Next, the technical solutions of the present utility model will be described clearly and completely in conjunction with the attached Figures 1 - 3 drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] An embodiment of the present application discloses a subgrade reinforcement structure. Referring to Figures 1 - 3 , it includes a bearing plate 1. A sloping plate 2 is fixedly connected to the top side of the bearing plate 1. A hinge sleeve 3 is fixedly connected to the right side of the sloping plate 2. A hinge shaft 4 is rotatably connected to the inner wall of the hinge sleeve 3. A support plate 5 is fixedly connected to the outer side of the hinge shaft 4. By providing the bearing plate 1 and the support plate 5, the bearing plate 1 is buried below the ground, and the subgrade is directly poured on the top side of the bearing plate 1. Moreover, the inclination angle of the support plate 5 is adjusted according to the inclination angle of the side slope of the subgrade until the support plate 5 fits with the soil on the side of the subgrade. After the poured subgrade solidifies, its own weight will directly act on the surface of the bearing plate 1. At this time, the greater the pressure received by the bearing plate 1, the higher the stability of the support of the support plate 5 on the side of the soil. Compared with the method of fixing with ground hooks in the comparative document, it can effectively avoid the situation that the stability of subgrade reinforcement is reduced due to the influence of external factors, so as to meet the subgrade reinforcement requirements in different situations and is conducive to popularization and use.

[0020] In the present application, a plurality of first limiting holes are opened on the front and rear sides of the sloping plate 2. Second limiting holes are opened on both the front and rear sides of the support plate 5. The inner walls of two of the plurality of first limiting holes are inserted with U-shaped bolts 6. The two U-shaped bolts 6 are respectively fixedly inserted into the inner walls of the two second limiting holes. By providing the U-shaped bolts 6, after the turning angle of the support plate 5 is adjusted, the two ends of the U-shaped bolts 6 are respectively inserted into the first limiting hole and the second limiting hole. At this time, the U-shaped bolts 6 can be used to limit and fix the turned support plate 5.

[0021] In this application, an angle measurement disk 7 is fixedly connected to the front end of the hinge sleeve 3. The angle measurement disk 7 is sleeved on the outside of the hinge shaft 4, and a pointer 8 is fixedly connected to the outside of the hinge shaft 4. By providing the angle measurement disk 7, when the support plate 5 is flipped, the angle measurement disk 7 and the pointer 8 are observed, so as to judge whether the current flipping angle of the support plate 5 meets the usage requirements, thereby improving the convenience.

[0022] In this application, a plurality of gripping plates 9 are fixedly connected to the top side of the bearing plate 1 and the right side of the support plate 5. The plurality of gripping plates 9 are arranged in a matrix distribution. By providing the gripping plates 9, when the roadbed is poured on the bearing plate 1, the plurality of gripping plates 9 can be used to improve the gripping force between the bearing plate 1 and the roadbed, thereby further improving the connection stability between the bearing plate 1 and the roadbed.

[0023] The standard parts used in this utility model can all be purchased from the market. The special-shaped parts can be customized according to the descriptions in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art. In addition, the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here.

[0024] The implementation principle of the roadbed reinforcement structure in the embodiment of this application is as follows: During use, the bearing plate 1 is buried below the ground, and the roadbed is directly poured on the top side of the bearing plate 1. Moreover, the inclination angle of the support plate 5 is adjusted according to the inclination angle of the soil slope on the side of the roadbed until the support plate 5 fits the soil on the side of the roadbed. After the poured roadbed solidifies, its own weight will directly act on the surface of the bearing plate 1. At this time, the greater the pressure received by the bearing plate 1, the higher the stability of the support plate 5 in supporting the soil side. Compared with the method of using ground hooks to fix in the comparative document, it can effectively avoid the situation that the stability of the roadbed reinforcement is reduced due to the influence of external factors, thereby meeting the roadbed reinforcement requirements in different situations and being conducive to popularization and use. After the flipping angle of the support plate 5 is adjusted, the two ends of the U-shaped bolt 6 are respectively inserted into the first limit hole and the second limit hole. At this time, the U-shaped bolt 6 can be used to limit and fix the flipped support plate 5. When the support plate 5 is flipped, the angle measurement disk 7 and the pointer 8 are observed, so as to judge whether the current flipping angle of the support plate 5 meets the usage requirements, thereby improving the convenience. When the roadbed is poured on the bearing plate 1, the plurality of gripping plates 9 can be used to improve the gripping force between the bearing plate 1 and the roadbed, thereby further improving the connection stability between the bearing plate 1 and the roadbed.
