Description

Technical Field

[0001] The utility model relates to a drainage pipe, in particular to a high-durability reinforced concrete drainage pipe, belonging to the technical field of underground drainage engineering. Background Art

[0002] In the prior art, for example, a utility model with application number 202220925062.3 discloses a reinforced concrete drainage pipe. By setting a pin shaft and a curing ring groove, when two adjacent pipe bodies are spliced, the pin shaft on one pipe body is inserted into the curing ring groove on the other pipe body, and then concrete is poured into the curing ring groove. After the concrete is cured, the adjacent pipe bodies can be relatively fixed. At this time, the concrete is filled on the inner side of the flared part, and the sealing effect is good. At this time, the pin shaft bears the pulling force between the adjacent pipe bodies. Therefore, the poured concrete will not be detached or cracked due to the misalignment of the two pipe bodies, thereby ensuring the sealing of the concrete casting.

[0003] Similar to the above application, there are still some shortcomings:

[0004] Both ends of the pipe body are made of cement. During the docking process, the pipe mouth will be squeezed, which is easy to cause damage to the cement at the pipe mouth, affecting the use effect and life. In the process of suspension, the outer side of the open end first contacts the concrete foundation at the bottom of the groove, which will be subject to a certain impact force, which is easy to cause damage to the concrete pipe. In addition, in order to ensure that the middle of the pipe body is smooth, the balance during suspension cannot be guaranteed. It is easy to slip during suspension, and the suspension safety is poor.

[0005] Therefore, a high-durability reinforced concrete drainage pipe is designed to optimize the above problems. Utility Model Content

[0006] The main purpose of the utility model is to provide a high-durability reinforced concrete drainage pipe. A first metal ring is provided on the inner side of the open end of the pipe body, and a second metal ring is provided on the outer side of the plug end, so that during the plugging process of the pipe body, the first metal ring fits with the second metal ring, effectively avoiding damage to the pipe body caused by excessive extrusion force, and improving the durability of the pipe body. The third limiting groove on the outer side of the open end of the pipe body and the buffer rubber ring inside it can make use of the buffer rubber ring to contact the concrete foundation at the bottom of the groove during suspension installation, effectively perform buffering, and reduce damage to the pipe body. The annular protrusion at the middle position of the pipe body can be arranged in the process of suspension. The suspension rope is located on both sides of the annular protrusion in the shape of an eight-shaped ring, which makes it more convenient to level the pipe body and avoids slipping during suspension, making it safer during installation.

[0007] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0016] The third limiting groove outside the open end of the pipe body and the buffer rubber ring inside the third limiting groove can effectively buffer the concrete foundation at the bottom of the groove during suspension installation, thereby reducing damage to the pipe body.

[0017] The setting of the annular protrusion on the outer side of the pipe body allows the suspension rope to be located on both sides of the annular protrusion in an eight-shaped ring during the suspension process, which makes it easier to level the pipe body and avoids slipping during the suspension process, making installation safer.
