Description

Technical Field

[0001] This utility model relates to the field of sealing and reinforcement technology, and in particular to a sealing and reinforcement structure for inclined butt-jointed reinforced concrete culverts. Background Technology

[0002] With the booming development of infrastructure construction, reinforced concrete culverts are widely used in underground drainage, water conveyance and channel projects. Among them, the beveled joint reinforced concrete culvert is favored for its advantages of convenient installation and good stress performance. It achieves the overlap between culverts through beveled design. Compared with flat culverts, it can better adapt to uneven settlement of the foundation and enhance the integrity of the pipeline system. However, the sealing and reinforcement of the beveled joint has always been a key issue in the project.

[0003] Sealing and reinforcement structures aim to prevent leakage and misalignment at culvert joints, ensuring the sealing and stability of the pipeline system. They consist of sealing materials and reinforcement components. Traditional sealing and reinforcement structures often use rubber ring seals combined with cement mortar tape. The rubber ring provides initial water-stopping, while the cement mortar further fills gaps and strengthens the connection. However, this method has many drawbacks. Rubber rings are susceptible to aging due to environmental factors, leading to seal failure. Cement mortar is prone to shrinkage cracks during hardening, making it difficult to accommodate small displacements between culverts, increasing the risk of leakage over long-term use. To address these issues, existing technologies employ a sealing and reinforcement method using elastic clamps in conjunction with rubber sealing rings. The elastic clamps apply radial pressure to ensure the rubber sealing ring fits tightly against the culvert joint, enhancing the sealing effect. However, this technology still has shortcomings. Elastic clamps require high installation precision; improper installation can lead to uneven stress, affecting the sealing and reinforcement effect. Furthermore, the long-term tightening force of the clamps decreases over time, making it difficult to maintain durable sealing and reinforcement performance. Additionally, installation is relatively complex, resulting in lower sealing effectiveness. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a sealing and reinforcement structure for inclined butt-jointed reinforced concrete culverts, aiming to improve the problem of the existing technology having difficulty in maintaining long-lasting sealing and reinforcement performance and low sealing effect.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a beveled butt joint reinforced concrete culvert sealing and reinforcement structure, comprising a pipe one, an insert pipe fixedly connected to the inner wall of the pipe one, a sealing ring fixedly connected to the right outer wall of the insert pipe, a receiving pipe fixedly connected to the outer wall of the insert pipe, an annular groove formed on the right side of the inner wall of the receiving pipe, a pipe two fixedly connected to the outer wall of the receiving pipe, an annular disc one fixedly connected to the outer wall of the pipe one, multiple wedge blocks fixedly connected to the right side of the annular disc one, an annular disc two fixedly connected to the outer wall of the pipe two, an installation groove formed on the inner wall of the annular disc two, and a reinforcement mechanism fixedly connected to the outer wall of the pipe two, the reinforcement mechanism being used for reinforcement.

[0006] As a further description of the above technical solution:

[0007] The reinforcement mechanism includes a clamp, with multiple square blocks fixedly connected to the left side of the clamp. Screws are threaded onto the inner wall of the square blocks. Multiple connecting columns are fixedly connected to the outer wall of the second pipe. An annular plate is fixedly connected to the outer wall of the connecting columns. A tie rod is fixedly connected to the bottom of the annular plate. A tapered column is fixedly connected to the bottom of the tie rod.

[0008] As a further description of the above technical solution:

[0009] The outer wall of the tapered column is fixedly connected to multiple reinforcing columns, and the left side of the annular plate is fixedly connected to multiple guide columns.

[0010] As a further description of the above technical solution:

[0011] A connecting ring is fixedly connected to the left side of the guide post, and multiple reinforcing ribs are fixedly connected to the inner wall of the connecting ring.

[0012] As a further description of the above technical solution:

[0013] An expansion seal strip is fixedly connected to the right side of the second pipe, and a lip ring is fixedly connected to the right side of the expansion seal strip.

[0014] As a further description of the above technical solution:

[0015] An L-shaped plate is fixedly connected to the top of the outer wall of the second pipe, and an installation hole is provided on the top of the L-shaped plate.

[0016] As a further description of the above technical solution:

[0017] A spiral iron strip is fixedly connected to the outer wall of the second pipe, and a protective pad is also fixedly connected to the outer wall of the second pipe.

[0018] As a further description of the above technical solution:

[0019] An I-shaped plate is fixedly connected to the bottom of the outer wall of the first pipe, and a support plate is fixedly connected to the bottom of the I-shaped plate.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the insertion pipe is inserted into the receiving pipe, and the sealing ring enters the annular groove at the same time. The sealing ring is squeezed between the insertion pipe and the receiving pipe, thereby achieving a seal. Under the squeezing action, the sealing ring is tightly fitted to the surface of the insertion pipe and the receiving pipe, preventing water from leaking from the interface. At the same time, the first annular disc and the second annular disc are moved closer to the interface, so that the wedge block enters the installation groove. The wedge block is wider on one side and narrower on the other side. During the embedding process, the gap at the interface is squeezed and compacted, which enhances the compressive strength. This achieves the functions of convenient installation and improved sealing effect, thus enhancing practicality.

[0022] 2. In this utility model, by installing a clamp on the outer wall of pipe one, inserting screws into the inside of the square block, and tightening the screws, the clamp tightly holds pipe one. The clamp generates radial pressure, which restricts the deformation of pipe one. It is connected to the annular plate through the connecting column, and driven into the foundation through the tie rod and the conical column. This can prevent pipe one from cracking due to excessive force, thus achieving the effect of reinforcing pipe one and pipe two, improving stability, and extending service life.
