Description

Technical Field

[0001] This utility model relates to the field of highway expansion joint repair technology, specifically a highway expansion joint repair structure. Background Technology

[0002] An expansion joint is a structural joint installed at an appropriate location along the construction joint direction of a building or structure to prevent cracks or damage caused by changes in climate temperature (thermal expansion and contraction). An expansion joint divides a building component above the foundation, such as a wall, floor slab, or roof (except for wooden roofs), into two independent parts, allowing the building or structure to expand and contract horizontally along its length. In the construction of highways, expansion joints are installed on the road surface at regular intervals. A search revealed that the existing publicly available technology, publication number CN115323944B, describes a repair structure and construction method for expansion joint areas of highway concrete bridges, including a set of support seats and a processing box. A set of support seats is arranged on both sides of the processing box, and the support seats are connected to the processing box. The processing box is provided with a feed port. One of the support seats is provided with a controller. The repair structure also includes: two sets of moving components, each set of moving components is symmetrically arranged on the support seats, for moving the repair structure on the road and adjusting the height of the processing box; a repair component, arranged between the set of support seats, for repairing the damaged area of ​​the expansion joint area; and a mixing component, arranged on the processing box and connected to the repair component, for mixing concrete. No manual repair is required, reducing labor input while ensuring the flatness of the repaired area of ​​the expansion joint area and not affecting the driving of passing vehicles.

[0003] In summary: In the above cases, the expansion joints were repaired by mixing concrete with equipment. However, since the filling concrete needs a certain amount of time to dry and solidify, and highways are subject to frequent traffic, repairing expansion joints with concrete not only has the problem of long drying and solidification time, but also the possibility that the concrete that is not dry or partially solidified will be damaged by passing vehicles. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a highway expansion joint repair structure. This addresses the issue raised in the background section where concrete is mixed using equipment to repair expansion joints. However, since the filled concrete requires a certain amount of time to dry and solidify, and highways are subject to frequent traffic, repairing expansion joints with concrete not only presents the problem of long drying and solidification time but also the risk of the partially or not fully dried concrete being damaged by passing vehicles.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a highway expansion joint repair structure, comprising a highway structure, wherein a repair structure is provided above the interior of the highway structure;

[0006] The highway structure includes a highway body with expansion joints, and fixing holes are provided on both sides of the highway body.

[0007] The repair structure includes an extension plate with an injection hole and an installation hole, and a through-hole limiting plate is fixedly installed inside the installation hole. At the same time, a grouting cylinder with a cavity column is welded and fixedly installed at the bottom of the extension plate.

[0008] By adopting the above technical solution, the grouting cylinder is set up to achieve the purpose of injection, accumulation and diversion.

[0009] Preferably, a support plate is welded and fixedly installed at the bottom of the grouting cylinder, and the extension plate is fixedly installed to the highway body by fixing bolts. An expansion agent is injected into the fixing hole, and a rain cap is installed inside the fixing hole to protect the fixing bolts.

[0010] By adopting the above technical solution, an expansion agent is used to achieve expansion and fixation.

[0011] Preferably, ultra-high performance concrete is injected into the injection hole, and the ultra-high performance concrete is injected above the surface of the support plate through the cavity column.

[0012] By adopting the above technical solution, ultra-high performance concrete can achieve rapid solidification.

[0013] Preferably, four fixing holes are provided, and the fixing holes are provided on the surface of the highway body.

[0014] By adopting the above technical solution, the fixing holes are used to achieve installation and fixation.

[0015] Preferably, the extension plate is shaped like an inverted convex character.

[0016] By adopting the above technical solution, the extension plate is used to open and fix the installation.

[0017] Preferably, the cavity columns are fixedly installed at equal intervals on the surface of the grouting cylinder, and the grouting cylinder is set in an inclined manner.

[0018] By adopting the above technical solution, the hollow column is used to guide, transport, and inject concrete.

[0019] Compared with the prior art, the beneficial effects of this utility model are: this highway expansion joint repair structure,

[0020] (1) This case solves the problem of repairing expansion joints by mixing concrete with equipment in the above case. However, the concrete needs a certain amount of time to dry and solidify. However, since highways need to be frequently used, repairing expansion joints with concrete not only has the problem of long drying and solidification time, but also the problem of the concrete not being dried or partially solidified being crushed by passing vehicles. When the expansion joints of the highway body need to be repaired, the operator places the extension plate carrying the grouting cylinder, cavity column and support plate inside the expansion joint. After the extension plate is initially fixed with the fixing bolts, the expansion agent is injected into the fixing hole to wrap and limit the fixing bolts, which further increases the fixing and anti-displacement effect of the extension plate. Then, ultra-high performance concrete is injected into the grouting cylinder and the injection hole, so that the ultra-high performance concrete overflows from the cavity column to the outside of the grouting cylinder, which increases the secondary fixing of the extension plate and the extension plate is easily vibrated and displaced.

[0021] (2) By setting up a rain cap, fixing hole, mounting hole, through hole limit plate and through hole limit plate, the problem of fixing bolts being easily exposed to the outside for a long time and easily developing rust and protrusion is solved. When the fixing nut is installed in a concealed manner by using fixing hole, mounting hole and through hole limit plate, not only is the concealment of the installation improved, but also the safety of the fixing nut after installation is increased and the protrusion of the fixing nut is reduced in the later stage. At the same time, the setting up a rain cap avoids the problem of the fixing nut being over-soaked and shortening its service life. Attached Figure Description

Detailed Implementation

[0027] 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.

[0028] Please see Figure 1-4 This utility model provides a technical solution: a highway expansion joint repair structure, such as... Figure 1 and Figure 2 As shown, the highway structure 1 includes a highway body 101 with an expansion joint 102. The highway body 101 has four fixing holes 103 on both sides. The fixing holes 103 are located on the surface of the highway body 101. The presence of four fixing holes not only demonstrates the insertability of the structure but also its filling capability. Furthermore, the presence of four fixing holes demonstrates the practicality and concealed installation capability of the structure.

[0029] like Figure 3 and Figure 4 As shown, a repair structure 2 is provided above the interior of the highway structure 1. The repair structure 2 includes an extension plate 201 with an injection hole 203 and an installation hole 202. The extension plate 201 has an overall "inverted convex" shape. This "inverted convex" shape not only reflects the compatibility of the component installation but also its practicality and secure connection. Furthermore, it demonstrates the axial symmetry of the component installation. A through-hole limiting plate 204 is fixedly installed inside the installation hole 202. Meanwhile, the extension plate 201... A grouting cylinder 205 with a hollow column 206 is welded and fixed at the bottom. The hollow column 206 is fixedly installed at equal intervals on the surface of the grouting cylinder 205, and the grouting cylinder 205 is set at an angle. When the above-mentioned components are set at equal intervals on the surface of the grouting cylinder 205, the aesthetics of the equal-interval setting of the above-mentioned components are reflected, as well as the distribution of the equal-interval installation of the above-mentioned components and the synchronous flow guidance and injection of the casting on both sides are reflected. Furthermore, when the grouting cylinder 205 is set at an angle, it is convenient for the ultra-high performance concrete 2011 to be injected and submerge the hollow column 206 to provide downward tension for the extension plate 201, thus avoiding the displacement or warping of the extension plate 201 in the later stage.

[0030] Furthermore, in the above scheme, a support plate 207 is welded and fixedly installed at the bottom of the grouting cylinder 205, and the extension plate 201 is fixedly installed to the highway body 101 by fixing bolts 208. An expansion agent 209 is injected into the fixing hole 103 through the installation hole 202. At the same time, a rain cap 2010 is installed inside the installation hole 202 to protect the fixing bolts 208. Ultra-high performance concrete 2011 is injected into the injection hole 203, and the ultra-high performance concrete 2011 is injected above the surface of the support plate 207 through the cavity column 206.

[0031] In the above scheme, when the expansion joint 102 of the highway body 101 needs to be repaired, the operator places the extension plate 201 carrying the grouting cylinder 205, the cavity column 206 and the support plate 207 inside the expansion joint 102. After the extension plate 201 is initially fixed with the fixing bolts 208, the expansion agent 209 is injected into the fixing hole 103 to wrap and limit the fixing bolts 208. Then, ultra-high performance concrete 2011 is injected into the grouting cylinder 205 and the injection hole 203, so that the ultra-high performance concrete 2011 overflows from the outside of the grouting cylinder 205 through the cavity column 206, increasing the secondary fixation of the extension plate 201 and preventing the extension plate 201 from being easily displaced by vibration.
