Description

Technical Field

[0001] The invention belongs to the field of pipeline emergency repair projects, and in particular relates to a repair and rescue device and an emergency repair method for a liner repair pipe. Background Art

[0002] The rapid development of society has led to a rapid increase in various urban pipelines. Common pipelines can be used to transport media such as water, gas, oil, and natural gas. During the long-term operation of the pipeline network, the pipelines will gradually age or corrode, resulting in a decrease in the pipeline's transmission capacity and even leakage, blockage, collapse, explosion, etc., which requires pipeline replacement and repair. The latest repair technology currently uses lined hoses for repair. This is simple and fast to construct, highly adaptable, and has good repair effects. However, once the lining is damaged after repair, it cannot be repaired and can only be reconnected using a joint. Therefore, it is urgent to invent a professional device to repair and rescue such repaired pipelines and seal the media in the pipeline. Summary of the Invention

[0003] To solve the above problems, the present invention discloses a repair and rescue device and a repair method for a liner repair pipe, which can quickly seal leakage points, reduce construction costs, shorten construction period, and improve construction efficiency.

[0004] To achieve the above object, the technical solution of the present invention is as follows:

[0005] A repair and rescue device for lined pipes includes a plug, a PU rubber part, a bushing, an elastic conical block, a clamp, a nut, a screw, a steel sheet, and a steel pipe clamp. The lower end of the plug is connected to the steel sheet, on which the PU rubber part is mounted. The PU rubber part and the steel sheet are mounted within the steel pipe. The bushing wraps around the outside of the plug, with its upper portion positioned above the steel pipe. The lower portion of the bushing is surrounded by an elastic conical block, which is mounted within the upper plane of the PU rubber part. A nut is fixed to the top of the plug.

[0006] As an improvement of the present invention, the horizontal line where the height of the steel sheet is located is consistent with the axis of the outer steel pipe.

[0007] As an improvement of the present invention, the clamp is a split clamp.

[0008] As an improvement of the present invention, a thread is provided on the plug.

[0009] The above-mentioned emergency repair method of the repair and rescue device for the liner repair pipe comprises the following steps:

[0010] (1) Open the leaking point of the outer steel pipe, connect the lower end of the plug to the steel sheet through a thread, place the PU rubber piece on the steel sheet, insert the plug into the hole of the leaking point, and make the PU rubber piece enter the lining repair pipe until the horizontal line of the steel sheet height is consistent with the axis of the outer steel pipe;

[0011] (2) Wrap the bushing around the outside of the plug, fix the clamp on the outside of the bushing, and embed the elastic conical block in the lower half of the bushing into the upper plane of the rubber part;

[0012] (3) Rotate the nut on the plug to press the bushing down, so that the outer circle of the PU rubber part expands and the elastic conical block presses the leakage point upward;

[0013] (4) Remove the nut and bushing, pass the plug screw through the hole on the upper side of the clamp, and secure the clamp;

[0014] (5) Tighten the nut on the plug and perform a pressure test at a pressure of 2.5 MPa to observe whether the medium is leaking.

[0015] The beneficial effects of the present invention are:

[0016] The repair and rescue device and repair method of the liner repair pipe described in the present invention can quickly seal the leakage point by tightening the nut from the top to make the elastic conical block press upward against the leakage point, thereby reducing construction costs, shortening construction period, and improving construction efficiency.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inward" and "outward" refer to directions toward or away from the geometric center of a particular component, respectively.

[0021] As shown in the figure, a circular hole is opened at the leakage point of the outer steel pipe 1, the lower end of the plug 2 is connected to the steel sheet 5 through a thread, the PU rubber part 6 is placed on the steel sheet 5, the plug 2 is inserted into the hole at the leakage point, and the PU rubber part enters the lining repair pipe until the horizontal line where the steel sheet height is consistent with the axis of the outer steel pipe; the bushing 3 is wrapped around the outside of the plug 2, the hoop 4 is fixed to the outside of the bushing 3, and the outer periphery of the lower half of the bushing 3 is wrapped with an elastic conical block 7, and the elastic conical block 7 is set in the upper plane of the rubber part 6; the rubber part 6 is set inside the outer steel pipe 1 , the rubber part 6 is placed on the steel sheet 5. The steel sheet is elastic and has an anti-corrosion layer on its surface; rotate the nut 8 on the plug 2, press the bushing 3 down, expand the outer circle of the PU rubber part 6, and the elastic conical block 7 presses the leakage point upward; remove the nut and bushing, pass the plug screw through the hole on the upper surface of the clamp 4, and fix the clamp; tighten the nut 8 on the plug 2, pull the steel sheet up to make the elastic conical block 7 press the leakage point upward; finally, perform a pressure test at a pressure of 2.5Mpa to observe whether the medium is leaking.
