Abstract
Description
Technical Field
[0001] The utility model relates to the field of tunnel engineering, in particular to a reinforcement structure for a shallow buried tunnel under a ditch. Background Art
[0002] The existing reinforcement structures of shallow tunnels under the ditches usually lack an integrated design and cannot effectively deal with the problem of ditch damage caused by loose foundation soil. Traditional reinforcement methods require frequent adjustments and supports during construction, which increases the difficulty and cost of construction. In addition, the existing reinforcement structures are prone to deformation and damage when subjected to long-term loads, making it difficult to ensure the long-term stability of the ditches. This not only affects the safe operation of the tunnel, but may also cause ditch leakage, threatening the safety of the surrounding environment and facilities. The existing ditch reinforcement structure has the following disadvantages:
[0003] 1. The existing reinforcement structure of the shallow tunnel under the ditch has limited effect in protecting the ditch. The traditional reinforcement method can only maintain the stability of the ditch to a certain extent, and cannot effectively protect the integrity of the ditch. Especially when the foundation soil is loose, the ditch may still be damaged. Therefore, there is an urgent need for a reinforcement structure that can fully protect the ditch through the ditch protection circular plate.
[0004] 2. The support of the reinforcement structure at the top of the ditch usually lacks effective design, which causes the circular plate of the ditch protection to be easily deformed or broken when subjected to top pressure, reducing the reliability of the entire reinforcement structure. Therefore, there is an urgent need for a reinforcement structure that can achieve top support through circular plate ribs.
[0005] 3. The existing reinforcement structure does not provide sufficient support at the bottom of the ditch. Especially when the foundation soil is loose, the bottom support of the circular plate often fails and cannot provide stable support force, thus affecting the reinforcement effect. Therefore, there is an urgent need for a reinforcement structure that can achieve bottom support through bottom pillars.
[0006] 4. The traditional reinforcement structure lacks an integrated design. When the foundation soil is loose, the reinforcement effects of each part cannot be coordinated, resulting in poor overall reinforcement effect. Therefore, there is an urgent need for an integrated reinforcement structure that can be achieved by reinforcing the bottom plate so that it can maintain stability under any circumstances and ensure the long-term safety of the ditch. Utility Model Content
[0007] The main purpose of the utility model is to provide a reinforcement structure for a shallow buried tunnel under a ditch, which can effectively solve the problems in the background technology.
[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0009] A reinforcement structure for a shallow tunnel under a ditch comprises a ditch, a ditch protection circular plate, a circular plate rib, a reinforcement vertical plate, a reinforcement bottom plate and a bottom support. The ditch protection circular plate is installed below the ditch to protect the ditch.
[0010] Preferably, the circular plate ribs are installed on both sides of the top of the channel protection circular plate.
[0011] Preferably, the bottom support is installed at the bottom of the channel protection circular plate.
[0012] Preferably, the reinforcement base plate is installed at the bottom of the entire reinforcement structure.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] 1. The utility model provides comprehensive protection for the ditch by installing the ditch protection circular plate. The ditch protection circular plate can effectively maintain the integrity of the ditch and prevent damage caused by loose foundation soil. This design ensures that the ditch remains stable during the tunnel underpass, avoids safety hazards caused by ditch damage, and improves the safety and reliability of tunnel construction.
[0015] 2. The utility model realizes the top support of the circular plate of the canal protection by installing the circular plate ribs. The circular plate ribs can enhance the bearing capacity of the circular plate of the canal protection and prevent it from deforming or breaking when subjected to the top pressure. This design improves the overall stability and durability of the reinforced structure and ensures the safety and reliability of the ditch in long-term use.
[0016] 3. The utility model realizes the bottom support of the canal protection circular plate by installing the bottom support. The bottom support can provide strong support force to prevent the canal protection circular plate from failing due to insufficient bottom support. This design enhances the overall strength and stability of the reinforcement structure, ensuring that the ditch can still be effectively protected when the foundation soil is loose.
[0017] 4. The utility model realizes the integration of the reinforcement structure by installing a reinforcement base plate. The reinforcement base plate can effectively connect the various parts of the reinforcement structure together to form a whole, and can maintain the stability of the reinforcement structure even when the soil below is loose. This design improves the overall reliability of the reinforcement structure, ensures the long-term stability and safety of the ditch, and significantly improves the safety and efficiency of tunnel construction and operation.

[0025] Example
[0026] See also Figure 1-3 , the utility model provides a technical solution:
[0027] A reinforcement structure for a shallow tunnel under a ditch comprises a ditch, a ditch protection circular plate, a circular plate rib, a reinforcement vertical plate, a reinforcement bottom plate and a bottom support. The ditch protection circular plate is installed below the ditch to protect the ditch.
[0028] Specifically, the circular plate ribs are installed on both sides of the top of the channel protection circular plate.

[0030] Specifically, the reinforcement base plate is installed at the bottom of the entire reinforcement structure.
[0031]
[0032]
[0033] By comparing the data in the above table, it can be seen that in terms of ditch protection, the ordinary reinforcement structure lacks effective protection, and the ditch is easily damaged. However, the reinforcement structure with the ditch protection circular plate effectively protects the integrity of the ditch and prevents damage by installing the ditch protection circular plate, which significantly improves the stability and safety of the ditch. In terms of top support, the support effect of the ordinary reinforcement structure is limited, and it is easy to deform, affecting the stability of the overall structure. The new reinforcement structure realizes the top support of the ditch protection circular plate by installing the circular plate ribs, enhances the stability and bearing capacity of the structure, and ensures safety during long-term use. In terms of bottom support, the support of the ordinary reinforcement structure is insufficient and easy to fail, especially when the foundation soil is loose, the reinforcement effect is difficult to guarantee. The new reinforcement structure realizes the bottom support of the ditch protection circular plate by installing the bottom pillar, enhances the bearing capacity, and can maintain the stability of the reinforcement structure even when the foundation soil is loose. In terms of integrated design, the ordinary reinforcement structure lacks integrated design, each part is independent, the integrity is poor, and it is easily affected by the external environment. The new reinforcement structure realizes the integrated design of the reinforcement structure by installing a reinforced base plate, ensuring the overall stability and reliability, and improving the service life and long-term safety.
