[0001] The utility model relates to the technical field of drainage pipes, in particular to a concrete drainage pipe with good sealing performance. Background Art

[0002] Concrete pipes are pipes made of concrete or reinforced concrete, used to transport fluids such as water, oil, and gas. They are divided into four categories: plain concrete pipes, ordinary reinforced concrete pipes, self-stressed reinforced concrete pipes, and prestressed concrete pipes.

[0003] For example, a Chinese patent discloses: an embedded steel cylinder reinforced concrete drainage pipe, announcement number: CN210661703U, which has high interface matching accuracy and structural strength, easy installation and alignment, good joint sealing performance, and forms an anti-seepage sealing structure through the steel cylinder and the socket and spigot steel rings to resist the water pressure inside and outside the drainage pipe, and can withstand the influence of foundation settlement and deformation within a certain range, thereby extending the service life.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems: there was a lack of cooperating devices during the connection and installation of the drainage pipes, and the installation of the drainage pipes usually relied only on observation and empirical judgment, which could easily lead to errors causing connection deviations and gaps causing water accumulation and reverse slopes.

During the connection process, the first connecting ring and the second connecting ring are aligned in parallel for matching, the drainage pipe body is rotated to make the first connecting ring rotate inside the second connecting ring, and the first connecting ring is limited by the spring to complete the connection, thereby improving the parallelism of the drainage pipe body during connection and making the sealing component fit more tightly, which is beneficial to improving the sealing performance and avoiding offset caused by the superposition of connection errors and gaps causing water accumulation and reverse slope. Example

[0032] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the technical solution in the embodiment of the present application is to effectively solve the problem of lack of matching devices during the connection and installation of the drainage pipe. The installation of the drainage pipe is usually carried out only by observation and experience judgment, which is prone to the technical problems of error superposition causing connection deviation and gap causing water accumulation and reverse slope. The overall idea is as follows: it includes a drainage pipe body 11, a socket 12 is opened on one side of the drainage pipe body 11, a rubber sealing ring 13 is sleeved on the outer surface of the socket 12, a water stop ring 14 is sleeved on the end of the outer surface of the socket 12 close to the rubber sealing ring 13, a socket steel ring 15 is sleeved on the outer surface of the socket 12, and a socket steel ring 15 is sleeved on the outer surface of the socket 12. The mouth steel ring 15 is sleeved on the outer surface of the socket 12 and the rubber sealing ring 13, and the outer surface of the drain pipe main body 11 is fixedly connected to one end of the socket 12, and the clamping mechanism includes a first connecting ring 16. The first connecting ring 16 is fixedly connected to one end of the outer surface of the drain pipe main body 11 close to the socket 12. The outer surface of the drain pipe main body 11 close to the first connecting ring 16 is provided with a lifting groove 17. Drainage is carried out by connecting multiple drain pipe main bodies 11. Before connection, the drain pipe main body 11 is lifted and transported through the lifting groove 17 opened on the outside of the drain pipe main body 11.

[0033] The drain pipe body 11 is provided with a socket 18 on the side away from the socket 12, and a second connecting ring 19 is fixedly connected inside the socket 18. The second connecting ring 19 cooperates with the first connecting ring 16, and a slide groove 21 is provided inside the second connecting ring 19. A spring 22 is sleeved inside the slide groove 21, and the spring 22 is fixedly connected to the inside of the drain pipe body 11. The inner surface of the spring 22 is sleeved with a limiting rod 23, and the limiting rod 23 is slidably connected to the inside of the slide groove 21. The drain pipe body 11 is connected by placing one end of the socket 18 into the inside of one end of the socket 18. When the socket 12 enters the inside of the socket 18, the first connecting ring 16 and the second connecting ring 19 are aligned parallel to each other for cooperation. After the cooperation is completed, the drain pipe body 11 is rotated to make the first connecting ring 16 rotate inside the second connecting ring 19. After rotating to the specified position, the spring 22 drives the limiting rod 23 to limit the first connecting ring 16 to complete the connection between the drain pipe bodies 11.

[0034] A grouting hole 24 is opened at one end of the drainage pipe body 11 close to the second connecting ring 19. The grouting hole 24 is connected to the socket 18. A polysulfide sealing paste 25 is sleeved inside the socket 18. The polysulfide sealing paste 25 and the grouting hole 24 are on the same vertical line. After the connection is completed, the rubber sealing ring 13 and the water stop ring 14 connected to the outer surface of the socket 12 play a sealing and fastening role in the interface, and the polysulfide sealing paste 25 is injected into the socket 18 through the grouting hole 24 to ensure that the drainage pipe body 11 maintains good air tightness and waterproofness under vibration and temperature changes.

[0035] In response to the problems existing in the prior art, the utility model provides a concrete drainage pipe with good sealing performance. During the connection process, the first connecting ring 16 and the second connecting ring 19 are aligned in parallel for cooperation. The drainage pipe body 11 is rotated to rotate the first connecting ring 16 inside the second connecting ring 19. The spring 22 drives the limiting rod 23 to limit the first connecting ring 16 to complete the connection, thereby improving the parallelism of the drainage pipe body 11 during connection, which is beneficial to improving the close fit of the sealing component, avoiding offset caused by the superposition of connection errors, and the appearance of gaps causing water accumulation and reverse slope.

[0036] Working principle:

[0037] The first step is to connect multiple drainage pipe bodies 11 to carry out drainage treatment. Before connection, the drainage pipe body 11 is lifted and carried by the lifting groove 17 opened on the outside of the drainage pipe body 11, and the drainage pipe body 11 is connected by placing one end of the socket 12 into one end of the plug 18. When the socket 12 enters the inside of the plug 18, the first connecting ring 16 and the second connecting ring 19 are aligned in parallel for matching. After the matching is completed, the drainage pipe body 11 is rotated to make the first connecting ring 16 rotate inside the second connecting ring 19. After rotating to the specified position, the spring 22 drives the limit rod 23 to limit the first connecting ring 16 to complete the connection between the drainage pipe bodies 11.

[0038] In the second step, after the connection is completed, the rubber sealing ring 13 and the water stop ring 14 connected to the outer surface of the socket 12 are used to seal and tighten the interface, and polysulfide sealing paste 25 is injected into the socket 18 through the grouting hole 24 to enable the drainage pipe body 11 to maintain good air tightness and waterproofness under vibration and temperature changes.

[0039] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
