Technical Field
[0001] This utility model relates to the field of highway engineering technology, specifically a roadbed planning model for highway engineering design. Background Technology
[0002] Highway engineering, a branch of civil engineering, focuses on the design, construction, maintenance, and improvement of roads. It encompasses all stages from initial planning and design to construction and material use, and finally to road maintenance and management. The main goal of highway engineering is to provide safe, efficient, and comfortable transportation facilities for vehicles and pedestrians. Highway engineering involves multiple aspects, including route design, pavement design, drainage design, traffic engineering, environmental engineering, construction management, and maintenance management. These components work together to ensure that roads provide high-quality transportation services throughout their expected service life while minimizing their impact on the environment and society. In short, highway engineering is a comprehensive project of road infrastructure construction and maintenance, aiming to provide people with good transportation conditions and promote economic development and social progress.
[0003] In the initial design phase of highway engineering, roadbed planning models are required. While traditional roadbed planning models have some display capabilities, they also have some shortcomings. For example, they are difficult to protect when not in use, making them susceptible to damage or impact from collisions or dust accumulation. Furthermore, their display effect is relatively limited, only providing cross-sectional structural displays and failing to provide comprehensive or cross-sectional structural displays as needed. Consequently, the display effect is not intuitive enough, significantly diminishing the overall display quality. Therefore, this paper proposes a roadbed planning model for highway engineering design to address these issues. Utility Model Content
[0004] The purpose of this utility model is to provide a roadbed planning model for highway engineering design, which can be protected when not in use, so it is not easily damaged or affected by collisions or dust. Moreover, its display effect is more comprehensive, not limited to providing cross-sectional structural display, but can provide full or cross-sectional structural display according to needs, so the display effect is more intuitive, thereby improving the overall display effect and solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A roadbed planning model for highway engineering design includes a base plate. A set of upper locking grooves are symmetrically formed at both ends of the top wall of the base plate, and a set of lower locking grooves are symmetrically formed at both ends of the bottom wall of the base plate.

[0021] Please see Figure 1-3 This utility model provides a technical solution:
[0022] A roadbed planning model for highway engineering design includes a base plate 1. A set of upper locking grooves 2 are symmetrically opened at both ends of the top wall of the base plate 1, and a set of lower locking grooves 3 are symmetrically opened at both ends of the bottom wall of the base plate 1. The upper locking grooves 2 and lower locking grooves 3 are positioned correspondingly and matched in specifications. A protective cover 4 is provided on the top of the base plate 1. A first half-mold 6 is fixedly connected to the rear side of the center of the top of the base plate 1, and a second half-mold 7 is provided to the front side of the center of the top of the base plate 1. A roadbed component 8 is provided in the inner cavity of the first half-mold 6, and adjustment components are symmetrically provided on both sides of the second half-mold 7.
[0023] The bottom of both sides of the protective cover 4 are symmetrically connected with snap-fit blocks 5. The snap-fit blocks 5 are positioned and matched with the upper snap-fit groove 2 and the lower snap-fit groove 3. When not in use for display, the protective cover 4 can provide protection for the first half mold 6 and the second half mold 7 by using the snap-fit blocks 5 at the bottom and the upper snap-fit groove 2. When in use for display, the snap-fit blocks 5 at the bottom and the lower snap-fit groove 3 can provide support for the base plate 1. The first half mold 6 and the second half mold 7 are of the same size, and the front wall of the first half mold 6 and the rear wall of the second half mold 7 are fitted together. The first half mold 6 and the second half mold 7 can form a complete roadbed, thereby providing a display effect for the roadbed as a whole. The adjustment component includes a drive motor 9 fixedly connected to both sides of the inner cavity of the base plate 1 and a drive motor 9 fixedly connected to both sides of the top wall of the base plate 1. The adjustment slot 10 corresponding to position 9 has a lead screw 11 on the output end of the drive motor 9. The top end of the lead screw 11 passes through the base plate 1 and the bottom wall of the adjustment slot 10 and extends into the inner cavity of the adjustment slot 10. This end is rotatably connected to the top wall of the inner cavity of the adjustment slot 10. A threaded seat 12 is threaded through and threadedly connected to the lead screw 11 and is slidably connected to the adjustment slot 10 in the longitudinal direction. A connecting rod 13 is fixedly connected to the side wall of the threaded seat 12 near the second half mold 7. The end of the connecting rod 13 away from the threaded seat 12 passes through the side wall of the adjustment slot 10 and is fixedly connected to the side wall of the second half mold 7. The adjustment component can provide the second half mold 7 with the ability to adjust its position, so that the first half mold 6 and the second half mold 7 are not limited to providing a single aspect of structural display, but can be fully or cross-sectionally displayed according to the needs. Therefore, the display effect is more intuitive, thereby improving the overall display effect.
[0024] Workflow: When not in use for display, the protective cover 4 can close the top of the substrate 1 by engaging the bottom latching block 5 with the upper latching slot 2, thus providing protection for the first half-mold 6 and the second half-mold 7. When in use for display, the bottom latching block 5 engages with the lower latching slot 3 to provide support for the substrate 1, exposing the top of the substrate 1. The first half-mold 6 and the second half-mold 7 are initially joined together to form a roadbed assembly, providing a visually appealing display. The adjustment component allows for positional adjustment of the second half-mold 7, enabling the first half-mold 6 and the second half-mold 7 to be flexible and not restricted. To provide a single-aspect structural display, when a cross-section needs to be displayed, the drive motor 9 is started. The drive motor 9 drives the lead screw 11 to rotate. As the lead screw 11 rotates, it drives the threaded seat 12 on the lead screw 11 to move. The threaded seat 12 drives the second half mold 7 to move upward through the connecting rod 13. After the second half mold 7 moves upward until its bottom is higher than the top of the first half mold 6, the drive motor 9 stops running. At this time, the roadbed component 8 in the first half mold 6 will be displayed. Therefore, this application can provide a full or cross-sectional structural display as needed, so the display effect is more intuitive, thereby improving the overall display effect.
