Description
Technical Field
[0001] This utility model relates to the field of culvert engineering technology, and in particular to a reinforcement structure for a high-fill arch culvert. Background Technology
[0002] Traditional high-fill arch culvert reinforcement design requires on-site formwork erection and on-site pouring, which has drawbacks such as large workload and long construction period, and has a significant impact on the construction site environment, thus limiting the reinforcement environment. Utility Model Content
[0003] The present invention aims to at least improve one of the technical problems existing in the prior art. To this end, the present invention proposes a reinforcement structure for high-fill arch culverts.
[0004] The technical solution of this utility model is as follows:
[0005] A reinforcement structure for a high-fill arch culvert, applied to a high-fill arch culvert, wherein the reinforcement structure is assembled and fitted to the inner wall of the high-fill arch culvert, and the reinforcement structure includes:
[0006] Reinforced concrete, wherein the reinforced concrete has multiple confining grooves;
[0007] The reinforced vault includes an intermediate vault and
[0008] Two side arches are located on either side of the central arch. The central arch is mortised and tenoned with the side arches. Multiple limiting blocks are distributed on the side walls of the side arches away from the central arch. The limiting blocks are adapted and fixed to the limiting groove.
[0009] In one possible technical solution, the arch crown is further reinforced to have an outer curved surface that faces away from the high-fill arch culvert.
[0010] The reinforcing structure also includes multiple dovetail tenons, which are embedded in the outer curved surface to fix the central arch and the side arch.
[0011] In one possible technical solution, the dovetail tenon is further made of high-strength steel plate.
[0012] In one possible technical solution, a plurality of first trapezoidal grooves are further provided on the side arch far from the limiting block, and the first trapezoidal grooves are in communication with the outer curved surface.
[0013] Multiple second trapezoidal grooves are provided on both sides of the central arch to accommodate dovetail tenons.
[0014] In one possible technical solution, the thickness of the reinforced arch is further uniform, and the depths of the first trapezoidal groove and the second trapezoidal groove are equal and smaller than the thickness of the reinforced arch.
[0015] In one possible technical solution, the reinforcement structure is further defined as a double-layer steel plate structure, meaning that both the inner and outer surfaces of the reinforcement structure are steel plates, with a high-strength concrete layer between the steel plates.
[0016] In one possible technical solution, the overall thickness of the reinforced structure ranges from 25cm to 30cm.
[0017] In one possible technical solution, the reinforced structure is further defined as a high-strength reinforced concrete structure with a thickness ranging from 25cm to 30cm.
[0018] The high-strength reinforced concrete structure includes a reinforced arch 22 composed of a high-strength reinforced concrete curved slab and a reinforced concrete structure composed of a high-strength reinforced concrete straight slab.
[0019] According to this utility model, the reinforcement structure for high-fill arch culverts allows for rapid on-site installation through a splicing assembly method of the arch top, eliminating the need for on-site pouring and resulting in high work efficiency. Utilizing a mortise and tenon structure to reinforce the arch top enhances its connection strength, increases stress resistance, and reduces assembly errors. This utility model can reinforce existing high-fill arch culverts, and its good integration with the inner wall of the culvert prevents the continued development of cracks in the original culvert, thereby reducing the internal forces and deformation of the original culvert structure.
[0020] This invention simplifies the construction process, shortens the construction period, and increases work efficiency. It also makes full use of the existing arch culvert, ensuring the combined load-bearing strength of the old arch culvert and the reinforced structure.
[0021] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

The high-fill arch culvert 1 includes an arch culvert base 11, an arch culvert sidewall 12, and an arch crown 13. The reinforcement structure 2 is assembled and fitted to the inner walls of the arch culvert sidewall 12 and the arch crown 13. The reinforcement structure 2 includes:
[0035] Reinforcing concrete 21, wherein the reinforcing concrete 21 has multiple limiting grooves;
[0036] The reinforced dome 22 includes an intermediate dome 221 and
[0037] Two side arches 222 are respectively located on both sides of the middle arch 221. The middle arch 221 and the side arches 222 are mortised and tenoned together. Multiple limiting blocks 2220 are distributed on the side walls of the side arches 222 away from the middle arch 221. The limiting blocks 2220 are adapted and fixed to the limiting groove.
[0038] It should be noted that the reinforced arch 22 has an outer curved surface that faces away from the high embankment arch culvert 1.
[0039] The reinforcing structure 2 also includes a plurality of dovetail tenons 223, which are embedded in the outer curved surface and are used to fix the intermediate arch 221 and the side arch 222.
[0040] In this embodiment, each reinforcing structure 2 is equipped with four dovetail tenons 223, which are respectively located at the connection between the side arch 222 and the middle arch 221. The positions of the four dovetail tenons 223 include, but are not limited to, being symmetrical about the central axis of the middle arch 221, which reduces assembly errors while improving the stress bearing capacity of the arch.
[0041] It should be noted that the dovetail tenon 223 is made of high-strength steel plate, which is used to overcome the influence of the stress on the top of the roadbed on the original arch culvert.
[0042] It should be noted that a plurality of first trapezoidal grooves 2221 are provided on the side of the side arch 222 away from the limiting block 2220, and the first trapezoidal grooves 2221 are in communication with the outer curved surface.
[0043] The middle arch 221 has multiple second trapezoidal grooves on both sides, corresponding to the first trapezoidal groove 2221. The openings of the second trapezoidal grooves match the openings of the first trapezoidal groove 2221, and are used to fit the dovetail tenon 223.
[0044] It should be noted that the thickness of the reinforced arch 22 is uniform, and the depths of the first trapezoidal groove 2221 and the second trapezoidal groove are equal and smaller than the thickness of the reinforced arch 22.
[0045] In actual construction, the reinforced concrete 21 includes, but is not limited to, assembled structures, depending on the actual arch culvert and its surrounding environment.
[0046] The reinforcement structure for high-fill arch culverts according to this utility model embodiment allows for rapid on-site installation via a spliced assembly method for the arch top, eliminating the need for on-site pouring and resulting in high work efficiency. Utilizing mortise and tenon joints to reinforce the arch top enhances its connection strength, increases stress resistance, and reduces assembly errors. This utility model can reinforce existing high-fill arch culverts, and its good integration with the inner wall of the arch culvert prevents the continued development of cracks in the original arch culvert, thereby reducing the internal forces and deformation of the original arch culvert structure.
[0047] This invention simplifies the construction process and shortens the construction period, resulting in high work efficiency. It also makes full use of the existing arch culvert, ensuring the combined load-bearing strength of the old arch culvert and the reinforced structure.
