Description

Technical Field

[0001] The utility model relates to the technical field of buried drainage pipes, in particular to a square buried drainage pipe structure. Background Art

[0002] A square drain pipe is a drainage pipe with a rectangular cross section, while a round pipe is a drainage pipe with a circular cross section. In comparison, a square drain pipe is more robust and can withstand greater water flow and sediment mass, making it suitable for use in situations with large water flows, such as rapids or peak drainage systems. Compared to round pipes, square drain pipes are more complicated to install. Due to the variety of connection and fixing methods for square drain pipes, more on-site construction and processing are required during installation.

[0003] When installing the square buried drainage pipe, the two drainage pipes are directly fixedly connected using a connecting structure. However, after the connection, due to the buried reason, there are too many factors that affect the stability of the drainage pipe, such as land subsidence, which leads to poor stability of the connection and even fracture. Due to the influence of the buried ground, the maintenance process is more complicated, so a square buried drainage pipe structure with a protective function is needed. Utility Model Content

[0004] The technical problem to be solved by the utility model is that a square buried pipe is directly connected under the soil layer. When in use, the connection is very likely to break due to the sinking of the soil layer, thus affecting the use. A square buried drainage pipe structure with a protective function is provided.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is: a square buried drainage pipe structure, including a first square tube, a second square tube and a protective mechanism, the first square tube is matched with the second square tube, the protective mechanism includes a fixed bottom plate, the top surface of the fixed bottom plate is evenly provided with a plurality of steel bar load-bearing columns, the tops of the steel bar load-bearing columns are commonly connected with a load-bearing top plate, a first sleeve matching the first square tube is connected between the steel bar load-bearing columns, a second sleeve matching the second square tube is connected between the steel bar load-bearing columns, the first square tube extends to the bottom end of the load-bearing bottom plate through the first sleeve, the second square tube extends to the bottom end of the load-bearing bottom plate through the second sleeve, the first sleeve and the second sleeve are symmetrically arranged, and the first sleeve and the second sleeve are both provided with a plurality of bolts connected to the first square tube and the second square tube.

[0006] As an improvement, a limiting plate located at the bottom ends of the first square tube and the second square tube is connected between the steel bar load-bearing columns to facilitate pre-embedded limiting of the protective mechanism.

[0007] As an improvement, an injection cavity is provided between the fixed bottom plate and the limiting plate, and a reinforced concrete layer is provided in the injection cavity. By injecting reinforced concrete into the injection cavity to connect with the adjacent foundation, the stability of the embedded part can be improved.

[0008] As an improvement, an anti-collision pad is provided on the bottom surface of the load-bearing top plate. The provision of the anti-collision pad can protect the water pipe structure when the load-bearing top plate is pressed down and tilted, thereby reducing the risk of damage.

[0009] As an improvement, a flange is provided between the first square tube and the second square tube, and the flange is located in the center of the protective mechanism. The connection operation between the first square tube and the second square tube is achieved through the flange, the connection is stable, and the protective mechanism protects the flange.

[0010] The advantages of the utility model compared with the prior art are: first, the protective mechanism is fixed under the foundation, then the first square tube and the second square tube are placed through the protective mechanism, and then the square tube is fixedly connected to the protective mechanism with bolts, so that the connection between the square tubes is stable, and the load-bearing top plate on the protective mechanism can support and protect the connection position, reducing the risk of crushing.
