A kind of pipeline emergency repair with pressure drainage sealer

Abstract

The invention discloses a pressure drainage sealer for pipeline emergency repair, which comprises a closed diversion box, a U-shaped support frame and a pipeline top pressure reinforcement plate, and is characterized in that: the closed diversion box is pressurized by the U-shaped support frame and the pipeline The reinforcement plate is fixed on the leaking pipeline, the airtight diversion box is provided with a diversion pipe, and a diversion valve is arranged on the diversion pipe, and the pipeline top pressure reinforcement plate is provided with a U-shaped support frame. The fixing hole is fixed by the fastening nut. Under the action of the top pressure structure, the drainage sealer is reinforced in the leakage water area. Through welding and diversion reinforcement measures, the drainage is decompressed to a weldable state under the action of diversion Next, the final seal is completed. The present invention is suitable for emergency repair and airtightness of steel pipes, cast iron pipes, glass steel pipes, and concrete pipes.

Description

technical field [0001] The invention belongs to the field of pipeline systems, in particular to a pressure drainage sealer for emergency repair of pipelines. Background technique [0002] my country's pressure pipeline engineering has a wide range of divisions, and pipelines are the main body of the project. From the perspective of the use of leakage water, due to the corrosion of steel pipes in different degrees, the corrosion of prestressed steel bars in concrete pipes, the aging of other pipes and other reasons, about 50% of my country's pipelines have been found to have leakage water in about 20 years of use. Hidden dangers seriously threaten the safe operation of the pipeline, and the operation management unit will often face emergency repair tasks. Once the water supply pressure pipeline leaks during the production process, it is difficult to repair it under dynamic conditions. Especially in the case of high medium pressure, it is generally necessary to close the uppe...

Problems solved by technology

This treatment method is time-consuming, expensive and affects normal production. If the external environment of pipeline maintenance is poor, such as external drainage is difficult, and emergency repair machinery (such as excavators, cranes, etc.) is difficult to enter, the repair cost will be even greater. The efficiency of emergency repair is low, and it takes a certain period of time to stop the water supply and pipeline operation. For continuous production of urban public pipelines and enterprises, leaks often occur. In the case of

More advanced processes, such as some methods of filling sealants, have a greater impact on the quality of the medium, and are difficult to operate when the medium is running, and the cost is high
