[0002] Urban drainage pipes refer to pipes used to collect and discharge domestic sewage, industrial wastewater and precipitation generated in urban areas.

[0003] When using pipes to discharge sewage during the urban sewage treatment process, in order to facilitate the recording of the discharge volume of sewage and rainwater inside the pipe, a water flow sensor is usually installed at the outlet of the pipe to record the discharge volume of water inside the pipe in real time. When the pipe body is installed, it is usually used under the road surface to facilitate the discharge of sewage and rainwater, which causes the surface of the pipe body to be squeezed all the time. After a long period of use, it is easy to cause cracks and collapse on the surface of the pipe body, thereby affecting the discharge effect of sewage and rainwater. Utility Model Content

At this time, the clamping block is pulled to slide outward on the inner wall of the reinforcement rod to a certain position, driving the first spring to be stretched, so that one end of the reinforcement rod is clamped into the mounting hole to a certain position, and then clamped into the clamping groove, fixing the inserted reinforcement rod in the inner wall of the pipeline body, supporting and reinforcing the inner wall, improving the overall pressure resistance of the pipeline body, and making it less likely to crack and collapse when it is installed under the road surface for use later, thereby improving the service life and facilitating use.

When the pipe body is inserted to a certain position, one end of the clamping rod will be stuck in the circular hole under the resetting action of the second spring, limiting the two adjacent pipe bodies, facilitating the subsequent fixing of the bolts, facilitating its installation, and improving the adaptability of the pipe body.

[0017] Preferably, one end of the clamping rod is fixedly connected to a pull block, and the cross section of the pull block is arc-shaped.

[0018] The effect achieved by the above components is that by providing the pulling block, the contact area of ​​one end of the clamping rod can be increased, making it easier to manually hold and pull it.

[0019] Preferably, a plurality of second limiting blocks are symmetrically and fixedly connected to the outer surface of one end of the pipe body, and the circular hole frame is inserted between two opposite second limiting blocks.

[0020] The effect achieved by the above components is that by setting the second limit blocks, when the circular hole frame is inserted between two opposite second limit blocks, the clamping rod can be quickly aligned with the circular hole, so as to facilitate its limited and fixed position.
