Description

Technical Field

[0001] The present application relates to the technical field of pipeline pressure resistance testing equipment, and in particular to a pipeline pressure resistance testing device. Background Art

[0002] When constructing a municipal drainage system, it is necessary to lay drainage pipes on the ground. The drainage pipes need to be tested for air tightness and impermeability. These tests are carried out inside the pipes and are easy to operate. When the drainage pipes are buried underground, the outer walls of the drainage pipes are squeezed by the surrounding soil. When the pressure exceeds the pressure limit of the pipes, the drainage pipes will be damaged. Therefore, it is necessary to conduct a pressure test on the drainage pipes to determine the pressure range of the drainage pipes.

[0003] The existing announcement number is CN209542290U, and the name is a device for pressure resistance test of concrete pipes, including a support platform for placing concrete pipes, including a gantry, a beam and a pressure rod spanning the support platform, the two vertical arms of the gantry are provided with a slide groove and a plurality of threaded holes, the threaded holes penetrate the slide groove, the beam and the slide groove are detachably connected, the pressure rod is slidably connected to the slide groove, a power device for driving the pressure rod to move is fixed on the beam, the output end of the power device is connected to the pressure rod, a pressure sensor is provided on the pressure rod, the pressure rod is driven to descend by a pressure source arranged on the gantry, pressure is provided to the outer wall of the concrete pipe, and the compressive strength of the concrete pipe is tested, and a pressure sensor is provided on the pressure rod to conveniently display the pressure value borne by the concrete pipe.

[0004] With respect to the above-mentioned related technologies, the inventors found that when the pipeline is squeezed, a power device is used to drive the pressure rod to move, squeeze the pipeline on the supporting platform, and a pressure sensor is used to transmit the pressing pressure. According to the degree of cracking of the pipeline, the pressure resistance range of the pipeline is judged. However, the outer end face of the pipeline is a circular structure. When the pipeline is squeezed, the circular structure pipeline will be offset on the supporting platform, resulting in uneven force on the pipeline and inaccurate pipeline pressure resistance detection.
