Description

Technical Field

[0001] The utility model relates to the technical field of subgrade engineering, and particularly relates to a subgrade pavement splicing structure for subgrade engineering. Background Technique

[0002] The subgrade is a structure that directly supports the track formed by filling or excavation, and is also called the lower structure of the line. The subgrade is connected with bridges and tunnels to jointly form the line. Depending on the terrain conditions, the subgrade has two basic forms: embankment and cutting, commonly known as filling and excavation. The role of the railway subgrade is to directly lay the track structure on the subgrade surface. Therefore, the subgrade is the foundation of the track. The subgrade load bears both the weight of the track structure, that is, the static load, and the dynamic load transmitted through the track when the train is running. The line structure jointly formed by the subgrade and the track is a relatively loosely connected structure form, and the ability to resist dynamic loads is weak. The materials used to build the subgrade, whether filled or excavated, are mainly earth-rock granular materials. Therefore, the subgrade is a geotechnical structure and is often invaded and damaged by changes in natural conditions such as geology, water, rainfall, climate, and earthquake. The resistance ability is poor. Therefore, the subgrade should have sufficient firmness, stability and durability. For high-speed railways, the subgrade should also have reasonable stiffness to ensure the smoothness and comfort of the train during high-speed driving.

[0003] When building subgrade engineering, a subgrade pavement splicing structure is required. For example, a Chinese patent discloses a subgrade pavement splicing structure for subgrade engineering, with the publication (announcement) number: CN117988179A, which includes a first subgrade, a second subgrade and a splicing plate. Connecting grooves are symmetrically opened on the outside of the splicing plate. An extension component for the first subgrade and the second subgrade is arranged on the outside of the splicing plate. The extension component includes an extension plate arranged on the splicing plate. Scale lines are symmetrically installed on the outside of the splicing plate. A plurality of sliding blocks are movably connected to the outside of the splicing plate. A first splicing rod is installed on the outside of the sliding block. A second splicing rod is movably connected to the outside of the first splicing rod. In the present invention, by setting an adjustment component, the height and horizontal position of the splicing head can be moved. At the same time, through the extension component, it is convenient to extend and contract the splicing plate. Thus, when the first subgrade and the second subgrade are stepped and lapped, it is convenient to adapt to use according to steps of different heights. The above patent is convenient to adapt to use according to steps of different heights during use, but it is not convenient for users to connect the subgrade pavement, resulting in inconvenience for users to connect the flat pavement during use and inconvenience for users to assemble, thus affecting the normal use of users.
