Description

Technical Field

[0001] This utility model relates to the technical field of municipal road surface repair devices, specifically a rapid repair device for municipal road surfaces. Background Technology

[0002] Traditional road repair requires manual breaking of damaged road slabs one by one, and then placing new road slabs in pre-drilled trenches in the road. At the same time, the new road slabs must be able to fit and adhere to the surrounding road slabs. When there are too many damaged road slabs, all the road slabs need to be broken and the broken pieces dug out manually. The entire repair process is inefficient and greatly delays the repair time, resulting in traffic disruption. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a rapid repair device for municipal road surfaces, which solves the problem of low efficiency in repairing damaged municipal road slabs.

[0004] To achieve the above objectives, this utility model provides a rapid road surface repair device for municipal roads, including a base plate for insertion into a pre-drilled trench in an external road. The base plate has several placement slots along its height direction, and the placement slots are evenly distributed along the length direction of the base plate. A road panel is placed in each placement slot, and the bottom edge of each road panel is stacked on the edge of the end face of the base plate. A limiting structure is provided between the road panel and the corresponding placement slot to allow for rapid placement of the road panel and to limit its position. A loading member is provided on the road panel to work in conjunction with the limiting structure to improve the load-bearing capacity of the road panel. A connecting member is provided on the bottom wall of the base plate to improve the connection strength between the base plate and the bottom wall of the pre-drilled trench in the external road.

[0005] The advantages of adopting the above technical solution are: when paving municipal roads, the base plate can be directly placed in the pre-drilled trench, and then the road panels can be placed sequentially in the installation slots to achieve the installation of several road panels. By placing a large number of base plates, the municipal road surface can be laid quickly. However, when the road panels are placed in the installation slots, the limiting structure restricts their movement, making it difficult for them to wobble or loosen, thus avoiding any impact on paving efficiency and subsequent traffic flow. Furthermore, if a single road panel on the base plate is damaged, repair personnel can break the damaged panel, remove the broken pieces, and replace them with new ones. The road slabs themselves are easily accessible. The placement grooves prevent broken slabs from becoming embedded in the trenches or colliding with or being crushed by surrounding slabs, thus avoiding damage to surrounding road slabs. Furthermore, compared to traditional methods where broken road slab fragments become stuck in the trenches and are difficult to clean, this technology allows repair personnel to easily retrieve the fragments, improving repair efficiency. The limiting structure also eliminates the need for repair personnel to adapt and fit the new road slab to surrounding slabs after placement, further enhancing repair efficiency. When multiple road slabs on the base plate are damaged, repair personnel can break the damaged slabs at the front or rear of the base plate. The road surface was damaged into fragments, exposing the underlying slab. Repair personnel then grasped the slab and lifted it at an angle to the surrounding municipal road. Several road panels on the slab rose simultaneously. A soft pad or collection bag used to collect fragments was placed on one side of the slab. The repair personnel then laterally swung the slab, causing it to tip over, allowing the damaged road panels to fall onto the pad or bag. This completed the one-time collection and cleaning of the damaged road panels, eliminating the need for repair personnel to pick up each fragment individually. The slab was then repositioned and new road panels installed. The aforementioned technology improves repair efficiency, saves repair personnel's physical strength, reduces labor intensity, reduces manual operation, lowers labor costs, and reduces environmental impact. The loading components in the aforementioned technology improve the load-bearing capacity of the road slab, thereby improving the road slab's utilization efficiency, indirectly reducing the repair frequency, and thus indirectly improving repair efficiency. The connecting components in the aforementioned technology improve the connection strength between the base plate and the bottom wall of the external trench after placement. The pre-set trench mentioned in the aforementioned technology is a process in the existing paving method, that is, digging trenches or channels on the ground to place road slabs, so that several road slabs are kept on the same horizontal plane.

[0006] The present invention further includes the following: the limiting structure includes several limiting blocks coaxially stacked on the bottom wall of the road panel, the radial cross-sectional area of ​​the limiting blocks gradually decreases from the top opening of the mounting groove toward the bottom wall of the mounting groove, a limiting edge is provided on the inner peripheral wall of the mounting groove corresponding to the position of each limiting block, and the outer peripheral wall of each limiting block is in contact with the inner peripheral wall of its corresponding limiting edge.

[0007] The advantages of adopting the above technical solution are: when the road slab is placed in the installation groove, several limiting blocks are simultaneously placed into the installation groove, and the outer peripheral wall of each limiting block abuts against the inner peripheral wall of its corresponding limiting edge, thereby achieving the limiting effect of the limiting block, thus preventing the limiting block from shaking or loosening and affecting subsequent traffic. At the same time, when the limiting block is subjected to radial load, the above technology can transmit part of the load to the limiting edge, part of the load is then transmitted to the base plate through the limiting edge, and part of the load is then transmitted to the external trench through the base plate, thereby achieving load distribution, improving the load-bearing capacity of the limiting block, and thus improving the service life of the limiting block.

[0008] The present invention is further configured such that: the limiting block is arranged in a disc shape; a plurality of the limiting blocks are integrally formed with the road panel and the plurality of limiting blocks are combined to form a limiting platform; the inner peripheral walls of the plurality of limiting edges are combined to form a limiting step surface; and the outer peripheral wall of the limiting platform is in contact with the inner peripheral wall of the limiting step surface.

[0009] The advantages of adopting the above technical solution are: the limiting block is disc-shaped and the outer peripheral wall of the limiting platform is always in contact with the inner peripheral wall of the limiting step surface, thereby increasing the contact area and the force-bearing area, thus avoiding stress concentration. At the same time, compared with square or rectangular limiting blocks, the disc-shaped limiting block does not have sharp edges, so that no collision will occur during torque transmission, thus avoiding damage to the limiting block.

[0010] The present invention further includes the following configuration: the loading member includes a first loading rib embedded in the limiting ladder platform, the radial section of the first loading rib is arranged in an arc shape and the raised part of the first loading rib is arranged facing the opening of the mounting groove, and several limiting blocks of each road panel are connected by the corresponding first loading rib.

[0011] The advantages of adopting the above technical solution are: the setting of the first loading rib in the above technology improves the connection strength between several limiting blocks, and at the same time improves the connection strength between the limiting blocks and the road panel. When the road panel is under load, part of the load is applied to the first loading rib, thereby improving the load resistance of the road panel. At the same time, the first loading rib is made of steel bars, which further improves the load resistance of the limiting blocks, so that the first loading rib can disperse and transmit high loads, thereby avoiding stress concentration.

[0012] The present invention further includes: the loading member further includes a second loading rib embedded in the limiting ladder platform, the radial section of the second loading rib is arranged in an arc shape and the raised part of the second loading rib is arranged facing the opening of the mounting groove, and several limiting blocks of each road panel are connected by corresponding second loading ribs, and the first loading rib and the second loading rib are arranged in an interlaced manner.

[0013] The advantages of adopting the above technical solution are: the setting of the second loading rib in the above technology improves the connection strength between several limiting blocks, and at the same time improves the connection strength between the limiting blocks and the road panel. When the road panel is under load, part of the load is applied to the second loading rib, thereby improving the load resistance of the road panel. At the same time, the second loading rib is made of steel bars, which further improves the load resistance of the limiting blocks, so that the second loading rib can disperse and transmit high loads, thereby avoiding stress concentration. Meanwhile, the first loading rib and the second loading rib are staggered to improve the torque transmission and dispersion ability, while avoiding stress concentration.

[0014] The present invention further comprises: the connector includes several connecting protrusions evenly distributed circumferentially on the bottom wall of the base, and the connecting protrusions are arranged in a conical shape.

[0015] The advantage of adopting the above technical solution is that the connecting protrusion is set in a conical shape to improve the grip of the base and prevent the base from shaking or shifting. Attached Figure Description
