Technical Field

The invention belongs to the field of pipeline emergency repair engineering, and particularly relates to a maintenance emergency device and an emergency method for a lining repair pipe.

Background

The rapid development of the society leads the rapid growth of various urban conveying pipelines, and common conveying pipelines can be used for conveying media such as water, coal gas, petroleum, natural gas and the like. In the long-term operation process of a pipe network, pipelines are gradually aged or corroded, so that the conveying capacity of the pipelines is reduced, and even leakage, blockage, collapse, explosion and other conditions occur, so that the pipelines need to be replaced and repaired. At present, the latest repair process adopts a lining hose for repair, the construction is simple and quick, the adaptability is strong, and the repair effect is good, but once the lining is damaged after the repair, the repair cannot be carried out, and the reconnection can only be carried out in a joint mode. Therefore, a professional device is invented to repair and rescue the repaired pipeline, so that the medium in the pipeline is blocked urgently.

The first-aid repair method of the repair and emergency device for the lining repair pipe comprises the following steps:

(1) opening a leakage point of the outer steel pipe, connecting a steel sheet to the lower end of the plug through threads, placing a PU rubber piece on the steel sheet, plugging the plug into a hole of the leakage point, and enabling the PU rubber piece to enter the lining repair pipe until the horizontal line of the steel sheet is consistent with the axial line of the outer steel pipe;

(2) wrapping the bushing outside the plug, fixing the anchor ear at the periphery of the bushing, and embedding the elastic conical block at the lower half part of the bushing into the upper plane of the rubber part;

(3) rotating a nut on the plug, pressing the bushing downwards to expand the outer circle of the PU rubber part, and enabling the elastic conical block to upwards press a leakage point;

(4) removing the nut and the bush, penetrating the plug screw through the upper hole of the hoop, and fixing the hoop;

(5) and screwing the nut on the plug, performing a compression test under the pressure of 2.5Mpa, and observing whether the medium leaks.

The invention has the beneficial effects that:

according to the maintenance and emergency repair device and the maintenance and emergency repair method for the lining repair pipe, the elastic conical block upwards presses the leakage point by screwing the nut above, so that the leakage point can be quickly plugged, the construction cost is reduced, the construction period is shortened, and the construction efficiency is improved.
