Abstract

The invention discloses a device for detecting repair compressive strength of a CIPP pipeline. The device comprises a connecting block, wherein a supporting box is fixed on the connecting block; a baffle is fixed in the supporting box; springs are arranged on both sides of the baffle; a sliding block is arranged at one end of the springs; a roller wheel is rotatably arranged at the end of the sliding block; an installation box is fixed at one end of the supporting box; a servo motor is fixed in the installation box; a first bevel gear is fixed on an output shaft of the servo motor; a second bevel gear is in transmission connection with the first bevel gear; a first screw rod is in transmission connection with the second bevel gear; a first transmission nut is in transmission connection with the first screw rod; a first connection frame is in transmission connection with the first transmission nut; a first top block is fixed at the end of the first connecting frame; a pressure sensor isarranged between the first top block and the first connecting frame; a supporting mechanism is arranged at one end of the installation box. By adopting the structure, the detection of the compressivestrength is realized, the structure is simple, and the operation is easy.

Description

technical field [0001] The invention belongs to the technical field of pipeline detection, and in particular relates to a CIPP pipeline repair compressive strength detection device, and at the same time, the invention also provides a CIPP pipeline repair compressive strength detection method. Background technique [0002] The CIPP pipeline repair method, since the 1980s, has been widely used in the renovation of pipelines in the fields of drainage, gas and petrochemical industries all over the world. Its working principle is: the outer layer of a non-woven lining pipe is coated with There are polymer coatings (PU or PE), first impregnated with polyester resin or epoxy resin, and then flipped into the sewer or sewage pipe by water gravity or compressed air pressure. Once the liner is fully installed in the main pipe, the resin is heated by water or steam to cause a chemical reaction to cure the resin. After the liner is cured, a new structural pipe will be formed in the origi...
