Description

Technical Field

[0001] The utility model relates to the field of concrete drain pipe construction, and particularly relates to a butt joint sealing structure for concrete drain pipes. Background Technique

[0002] A concrete drain pipe is a pipe made of concrete, mainly used for discharging sewage, rainwater or farmland irrigation and drainage, etc. This kind of pipe has high corrosion resistance and strong bearing pressure. During construction, multiple pipe bodies need to be butted to meet the required drainage construction requirements. This solution specifically relates to a butt joint sealing structure for concrete drain pipes;

[0003] When the existing butt joint sealing structure of concrete drain pipes is in use, the pipe body is made of concrete. Since there are gaps at the butt joint of the pipe body, it is easy to leak, which is not convenient for quick butt joint sealing. It is necessary to pour concrete at the butt joint or use sealing water for sealing, which is not convenient for later disassembly and maintenance. And the butt joint of the two pipe bodies is easy to shift after a long time, which is not convenient for connection and fixation. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a butt joint sealing structure for concrete drain pipes, which can effectively solve the technical problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A butt joint sealing structure for concrete drain pipes includes a pipe body. A connecting component is installed at the butt joint of the pipe body. The connecting component includes a groove and a convex ring. The groove is opened at the front end of the pipe body, and the convex ring is cast at the rear end of the pipe body. A first sealing ring is filled in the inner circle of the groove, and a second sealing ring is sleeved on the outer circle of the convex ring. A connecting sleeve is installed at the butt joint of the pipe body. A first connecting groove is opened at the outer periphery of the connecting sleeve near the rear end, and a second connecting groove is opened at the inner circle of the connecting sleeve near the front end.

[0007] As a further scheme of the utility model, the inner diameters of the front end and the rear end of the pipe body are equal, and the inner diameter of the groove is equal to the outer diameter of the convex ring.

[0008] As a further scheme of the utility model, clamping rings are arranged on the inner circle of the first sealing ring and the outer circle of the second sealing ring, and clamping grooves are arranged on the outer wall of the first connecting groove and the inner wall of the second connecting groove.

[0009] As a further scheme of the utility model, the first sealing ring is sleeved in the first connecting groove and is arranged in a clamping connection, and the second sealing ring is filled in the second connecting groove and is arranged in a clamping connection.

[0010] As a further solution of the present utility model, a positioning component is installed on the outside of the pipe body. The positioning component includes two fixing sleeves, and the two fixing sleeves are respectively cast at both ends of the outside of the pipe body. A plurality of bolt grooves are respectively formed at the front and rear ends of the two fixing sleeves, and a plurality of screw holes are formed through the front and rear parts of the connecting sleeve. Connecting bolts are connected and installed through the bolt grooves and the screw holes.

[0011] As a further solution of the present utility model, the two fixing sleeves are symmetrically arranged, and the outer diameter of the fixing sleeve is equal to the outer diameter of the connecting sleeve.

[0012] As a further solution of the present utility model, a plurality of the screw holes and the connecting bolts are arranged in a surrounding manner, and the connecting bolts are threadedly connected through the screw holes.

[0013] The beneficial effects of the present utility model are as follows:

[0014] By setting the connecting component, the first sealing ring is placed in the groove, and the second sealing ring is sleeved on the convex ring. Through the connection of the connecting sleeve, the quick docking of the two pipe bodies is facilitated. Through the clamping between the clamping rings of the first sealing ring and the second sealing ring and the clamping grooves of the first connecting groove and the second connecting groove, the docking parts of the two pipe bodies can be closely fitted, improving the sealing between the two pipe bodies and reducing the use of concrete pouring and sealing glue;
