Description

Technical Field

[0001] The utility model relates to the technical field of concrete pipeline detection, in particular to a reinforced concrete pipeline detection device. Background Art

[0002] Pipeline pressure test is an important part of pipeline engineering and an effective method to check whether the pipeline manufacturing and installation quality are qualified or not. Pipeline pressure test usually adopts water pressure test. According to the pipe inspection and test requirements stipulated in the current national standards GB / T11836-2009 "Concrete and reinforced concrete drainage pipes" and GB / T16752-2006 "Concrete and reinforced concrete drainage pipe test methods", the single pipe section is filled with water to test the anti-seepage of the pipe body and the water sealing performance of the pipe interface. This can no longer reflect the water sealing performance of the pipe body interface, and cannot simulate the actual working conditions of the pipe socket connection during the pipeline jacking construction process.

[0003] The utility model patent with patent number CN212059253U discloses an internal pressure detection device for concrete pipes, including a seal for sealing two ports in the length direction of the concrete pipe, one port of the concrete pipe is connected with an inlet pipe and an outlet pipe, the inlet pipe is connected with an inlet valve, and the outlet pipe is connected with an outlet valve. When the concrete pipe needs to be tested for internal pressure, the concrete pipe is first placed in the groove, and the first sealing plate and the second sealing plate are slid, and the first rubber plug and the second rubber plug are respectively inserted into the two ports in the length direction of the concrete pipe. Then the first rubber ring and the second rubber ring are fixed by a fixing ring, and the first sealing plate and the second sealing plate are fixed to the two ends of the concrete pipe by a fixing nut. At this time, the inlet valve can be opened to pass water into the inlet pipe, and the water will flow into the concrete pipe. It can be observed whether there is water leaking from the outer wall of the concrete pipe. Finally, the outlet valve can be opened to discharge the water in the concrete pipe through the outlet pipe; in the patent, the first sealing plate is provided with a round cake-shaped first rubber plug on the side close to the concrete pipe, and the second sealing plate is provided with a round cake-shaped second rubber plug on the side close to the concrete pipe. The first rubber plug is inserted into one port of the concrete pipe with an interference fit, and the second rubber plug is inserted into the other port of the concrete pipe with an interference fit, and the concrete pipe is supported by a support frame. Since concrete pipes have different specifications and inner diameters are different, when the concrete pipe is supported by the support frame, due to the fixed height of the support, it is difficult to make the centers of concrete pipes with different inner diameters placed on the support frame easily offset from the first rubber plug and the second rubber plug, thereby causing the problem of difficulty in sealing both ends of the concrete pipe; at the same time, when testing the airtightness of the interface of the two concrete pipes, the two concrete pipes need to be plugged in. In this patent, since the position of the support is fixed, when plugging the two concrete pipes in, it is necessary to push the two concrete pipes to move on the support frame. Due to the large friction between the outer wall of the concrete pipe and the support frame and the large weight of the concrete pipe, it is difficult to move the concrete pipe to plug the two concrete pipes in and then test the sealing at the interface.
