Description

Technical Field

[0001] This utility model relates to the field of cement culvert production technology, and in particular to a side ditch structure for a semi-circular cement culvert. Background Technology

[0002] Cement culverts refer to cement pipes buried underground or used in projects such as culverts. They are mainly used for infrastructure construction such as drainage and water conveyance. They are widely used in urban rainwater and sewage discharge pipelines, which can effectively transport rainwater and sewage to treatment sites and ensure the normal operation of urban drainage systems. They can also be used as water conveyance pipelines for farmland irrigation, delivering water to farmland to meet the irrigation needs of crops. Both ends of cement culverts are equipped with side ditch structures. Existing side ditch structures include semi-circular cement culvert side ditch structures, U-shaped cement culvert side ditch structures, rectangular cement culvert side ditch structures, and trapezoidal cement culvert side ditch structures. Regardless of the type of side ditch structure used, gaps will appear at the joints of the cement culverts, resulting in water leakage and waste of water resources. Summary of the Invention

[0007] Preferably, the outer wall of the annular card block is wrapped with an annular sealing gasket, and the annular sealing gasket is made of flexible rubber material.

[0008] Preferably, both the annular card block and the arc-shaped card slot have trapezoidal cross-sections.

[0009] Preferably, the fastener includes a clamping plate symmetrically arranged on the outer wall of the second connector. The clamping plate has a circular hole. The cement culvert body has a symmetrically arranged mounting groove on one side that cooperates with the clamping plate. The mounting groove is located at one end of the first connector. A threaded sleeve is pre-embedded in the mounting groove. A locking bolt that cooperates with the threaded sleeve is provided in the circular hole.

[0010] Preferably, both connector one and connector two are made of steel plate.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0012] This utility model facilitates the connection of cement culvert bodies by using connector one, connector two, and fasteners. The operation is simple and convenient, improving the efficiency of cement culvert body installation. The interplay of the annular locking block and the arc-shaped groove increases the contact area between connector one and connector two, thereby improving the stability of the cement culvert body connection. The use of an annular sealing gasket enhances the sealing performance between the annular locking block and the arc-shaped groove, preventing water leakage between cement culvert bodies and avoiding water waste.

[0021] A side ditch structure for a semi-circular cement culvert includes a cement culvert body 1. A connector 2 is provided on the outer side of one end face of the cement culvert body 1, and a connector 3 is provided on the inner side of the other end face. Both connector 2 and connector 3 are made of steel plate, which facilitates the connection of each cement culvert body 1 together. A fixing component is provided on connector 3. The use of the fixing component facilitates the connection of connector 2 and connector 3 together to realize the connection of the cement culvert body 1. The operation is simple and convenient, and improves the installation efficiency of the cement culvert body 1.

[0022] Multiple arc-shaped grooves 4 are evenly provided on the inner wall of connector 12, and multiple annular blocks 10 that cooperate with the arc-shaped grooves 4 are evenly provided on the outer wall of connector 23. Through the mutual cooperation of the annular blocks 10 and the arc-shaped grooves 4, the contact area between connector 12 and connector 23 can be increased, thereby improving the stability of the connection of the cement culvert body 1.
