Embodiment 1

[0011] A method of repairing a sewer includes the steps of:

[0012] (1) Take the pipe collar or expansion joint and measure it on the repaired pipe, and mark with a pencil on the repaired pipe where the pipe is estimated to extend halfway into the pipe collar and expansion joint;

[0013] (2) Use a hacksaw blade to cut off the edge of the middle boundary along the inner wall of the pipe collar and expansion joint on the market, and polish it along the inner wall with sandpaper to make the pipe collar and expansion joint The internal diameter of the pipeline is larger than that of the pipeline being repaired;

[0014] (3) Then put the pipe clamp and expansion joint in step (2) on the repaired pipe respectively, apply glue, and move the pipe clamp and or expansion joint along the pipe, just to expose the mark made in advance, and wait for the glue to solidify .

Abstract

The invention belongs to the technical field of sewer repairing technology, particularly relates to a sewer repairing method and solves the problem that during pipeline repairing, the surface is divided unevenly since the contacting surface of a pipe fastener and an telescopic joint cannot be controlled. The method includes 1, comparing and measuring a pipe fastener or telescopic joint with a pipe to be repaired at first, estimating the position of half of the pipe extending into the pipe fastener or telescopic joint, and marking on the pipe to be repaired through a pencil; 2, sawing a rib dividing the pipe fastener or telescopic joint, existing in market, along the inner wall of the pipe fastener or telescopic joint, and polishing the inner wall through a piece of polishing paper to allow the inner diameter of the pipe fastener or telescopic joint to be larger than the pipe to be repaired; 3, sleeving the pipe to be repaired with the pipe fastener or telescopic joint after the step 2, coating with glue, moving the pipe fastener or telescopic joint along the pipe till exposing the made mark, and waiting for glue solidification.

Description

technical field [0001] The invention belongs to the technical field of sewer pipe repair, and in particular relates to a method for repairing a sewer. Background technique [0002] At present, PVC pipes are widely used in drainage facilities in the construction industry. This material is convenient and quick to install, but it is easy to damage. When the master worker installs a new sewer, there are ready-made pipes and pipe fittings on the market. When extending the pipe, pipe clamps or expansion joints are used. There is a dividing edge in the middle of this pipe clamp or expansion joint. It can ensure that the two contact surfaces of the connected pipe are inserted evenly, and there will be no phenomenon that one side is more and the other is less. This kind of pipe collar and expansion joint are better used when newly installing pipes. However, when repairing sewer pipes, such pipe collars and expansion joints are not easy to use. Because when repairing the sewer pipe,...
