[0002] Setting up temporary widening zones on narrow road sections can effectively solve the problem of difficult passing, especially on rural roads or old urban roads. It can provide a safe and stable temporary passage space for two-way vehicles, avoiding collisions caused by avoidance. The widened area uses a structural design to bear the wheel load, preventing vehicles from getting stuck, bumping, or damaging the roadbed when driving onto the soft shoulder. This significantly improves driving safety and passenger comfort. At the same time, widening the road helps to optimize traffic organization, rationally divert vehicles, reduce congestion points, and improve regional traffic.

[0003] In existing technologies, road widening structures mostly adopt on-site monolithic concrete casting, which involves complex construction procedures, requiring formwork and curing, with a cycle of several days or even longer, severely impacting traffic efficiency. This method relies on heavy machinery, making it difficult to implement quickly on narrow road sections, and once cast, it cannot be dismantled or reused, lacking flexibility. Demolition also leaves behind a large amount of construction waste. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides an embodiment of a widening structure for a municipal road, including a filling plate 1 as a widening base layer. The upper surface of the filling plate 1 is provided with a downwardly recessed receiving groove 10, which is filled with a layer of rubber particles cured by an adhesive. The bottom of the receiving groove 10 is provided with crisscrossing reinforcing plates 11, which are fixedly connected to the filling plate 1 to enhance the overall rigidity and deformation resistance of the widening structure. The bottom of the filling plate 1 is connected to a connecting component, which includes a connecting post 21 inserted into the ground. The outer wall of the connecting post 21 is provided with a cone 211 for increasing friction. An expansion component is provided inside the connecting post 21, which includes a pull block 31 for offsetting the outer wall of the connecting post 21 outward. The surfaces of the filling plate 1, the connecting component, and the expansion component are coated with anti-rust paint. The combination of filler plate 1 and rubber granule layer facilitates rapid installation and can also cope with a certain degree of thermal expansion and contraction. Reinforcing plate 11 improves the compressive and bending resistance. The cooperation between connecting column 21 and expansion component achieves firm anchoring with the foundation, significantly improving the anti-slip ability of the widened structure. Surface anti-rust treatment effectively extends the service life of the structure in humid environments and reduces rust problems.

[0024] Please see Figure 1-5 A further embodiment of this solution is as follows: The connecting column 21 and the filling plate 1 are provided with through holes 210. The bottom of the connecting column 21 has a ring array of upwardly extending crack grooves 213. The maximum outer diameter of the pull block 31 is larger than the diameter of the through hole 210. The through hole 210 provides a channel for the installation and adjustment of the expansion assembly, while the crack grooves 213 enable the bottom of the connecting column 21 to have radial expansion capability. When the pull block 31 is pulled upward, its design, with an outer diameter larger than the through hole 210, can forcibly compress the hole wall, causing the bottom of the connecting column 21 to open outward, greatly enhancing the interlocking force with the surrounding soil and significantly improving the pull-out resistance.

[0025] Please see Figure 1-4 A further solution based on this embodiment is: the top edge of the pull block 31 is provided with an inclined surface 311 for fitting the through hole 210. The inclined surface 311 allows the pull block 31 to smoothly contact the edge of the through hole 210 during the upward pulling process and guides it to enter smoothly, reducing the risk of jamming.

[0026] Please see Figure 1-4 A further embodiment of this solution is as follows: A pull post 32 is provided at the top of the pull block 31. A threaded surface 322 is machined on the radial surface of the pull post 32. A baffle 212 is provided inside the through hole 210, and a threaded hole corresponding to the threaded surface 322 is provided on the baffle 212. Through the threaded engagement between the pull post 32 and the threaded hole of the baffle 212, precise and controllable movement of the pull block 31 is achieved, making operation simple. The threaded connection has self-locking properties, which can maintain a stable position to a certain extent after expansion to the desired position.

[0027] Please see Figure 2-5 A further solution based on this embodiment is that the pull column 32 is provided with a hexagonal hole 320 for inserting a hexagonal wrench. The hexagonal hole 320 facilitates the use of a standard hexagonal wrench for rotational operation, making the tool highly versatile and construction convenient; assembly and adjustment can be completed in a confined space, improving on-site construction efficiency and reducing reliance on large equipment.

[0028] Please see Figure 2-5 A further embodiment of this solution is as follows: the radial surface of the pull post 32 is arrayed with wing plates 321. The wing plates 321 not only increase the contact area between the pull post 32 and the subsequent filling material, improving the connection strength and effectively preventing the pull post 32 from rotating and loosening during use, ensuring long-term stability of the expansion state, but also allow for manual adjustment of the pull post 32 due to the presence of the wing plates 321.

[0029] Please see Figure 2-5 A further solution based on this embodiment is as follows: the connecting column 21 is welded to the bottom of the filling plate 1, and the area corresponding to the top of the filling plate 1 and the bottom of the receiving groove 10 in the perforation 210 is filled with cement mortar containing stones. The cement mortar containing stones can improve the strength and crack resistance of the mortar, reduce the possibility of the large torsional rotation of the flange 321 damaging the mortar, and improve the shear resistance and durability.

[0030] Please see Figure 2-5 A further solution based on this embodiment is as follows: cement mortar containing stones is placed in the gaps between different flanges 321 to prevent the tie column 32 from rotating after the position of the tie block 31 is determined. After the tie column 32 is adjusted, the gaps between the flanges 321 are filled with cement mortar to form a physical barrier, completely locking the position of the tie column 32 and preventing the threads from loosening or rotating due to vehicle vibration or soil creep. This ensures the long-term effective operation of the expansion assembly and greatly improves the long-term stability and safety of the entire widening structure.

[0031] Working Principle: This structure is used for temporary widening of narrow municipal roads, aiming to provide temporary passing space for cars weighing less than two tons, preventing vehicle tires from running over the roadside soil and causing sinking or bumpy driving due to height differences. During construction, the filling plate 1 is laid on the shoulder or edge area to be widened, and the connecting post 21 at its bottom is inserted into the soil below. Then, a hexagonal wrench is inserted into the hexagonal hole 320 of the tie post 32 and rotated, driving the tie post 32 to move upward along the screw hole axis of the baffle 212, causing the pull block 31 to gradually enter the through hole 210 of the connecting post 21. Since the maximum outer diameter of the pull block 31 is larger than the diameter of the through hole 210 and has an inclined surface 311 at the top, it will strongly squeeze the hole wall during its upward movement, forcing the bottom of the connecting post 21 to expand outward along the crack groove 213. At the same time, the insert cone 211 is embedded in the soil layer, forming a firm anchoring structure. After expansion, cement mortar containing stones is filled into the upper part of the perforation 210 and the gap in the wing plate 321. After curing, it can lock the position of the tie post 32 and enhance the overall integrity. Then, the receiving groove 10 is filled with a layer of rubber granules cured with a binder. The filling plate 1 and the composite base layer above it, consisting of the rubber granule layer and the reinforcing plate 11, can withstand the load of the car vehicle, prevent the wheels from sinking into the mud, and improve driving stability and safety. This structure is easy to install and can be quickly deployed. It is suitable for temporary passing in space-constrained road sections. The tie block 31 and the tie post 32 are interlocking, and the interlocking part is coated with thread-locking adhesive.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
