Diagnosis of the depression amount of the back of the pipeline and filler injection device and diagnosis of the backside depression of the pipeline using the same and filling method

摘要

The present invention relates to an apparatus for diagnosing and filling a recess in the back of a pipeline and a method for diagnosing and filling a recess in the back of a pipeline using the same, in particular, a pipe-type frame disposed on a horizontal center line; A pair of side plates having a washer shape and fixed integrally in a state in which both ends of the pipe-shaped frame are respectively fitted in the center hole; A plurality of wheels respectively installed at end portions of the plurality of supports that are inclined and elastically installed on the outside of the side plates to roll along the inner surface of the pipe and allow the depression diagnosis and filling material injection device to be moved in the pipe; A traction line for moving the depression amount diagnosis and filling material injection device in any one direction in the pipeline corresponding to the operation direction of the winch or the winder installed on the ground in a state where one end portion is detachably installed on the outer surfaces of the side plates; A cylindrical hermetic tube in which both openings are fixed to outer surfaces of the side plates in a state of surrounding the pipe-shaped frame and the side plates; An air supply hose having one end coupled to an air inlet formed in one side plate of the side plates and injecting compressed air generated from an air pressure generator installed on the ground into the cylindrical hermetic tube; Equipped with a discharge air detection gauge and a vacuum pump, part of which is coupled to an air inlet formed from the center of the cylindrical sealed tube outward through one side plate to discharge the air in the depressions and loose ground parts to the outside An air exhaust hose; A camera having a light and installed on one side of the two side plates; Filler material having a pressure gauge and a filler injection pump, part of which is connected to a filler inlet formed outwardly from the center of the cylindrical hermetic tube through one side plate and supplied from the outside into the depression and the loose ground It characterized in that it comprises a; filling material supply hose. Therefore, it is possible to improve the safety according to the diagnosis and repair of the pipeline, to prevent unnecessary bumps on the ground around the pipeline, and to improve the constructability and the diagnosis and filling by increasing the rate of filling of the back of the pipeline and increasing the filling material filling speed. The quality of diagnosis and reinforcement can be greatly improved by improving accuracy.
