Pressure plugging is a technique commonly used in engineering construction to prevent groundwater, geological gases, or other liquids from entering the construction site, as well as to control, regulate, and plug the pressure in a pipeline or wellbore. It is an effective stability protection measure that can protect construction personnel and equipment from the hazards of groundwater pressure, geological gases and other substances.

In all kinds of underground engineering, underground mining or pipeline construction, the technology of writing tape sealing is often applied. It can keep the relatively dry work site and reduce the impact of cement slurry and other substances on the construction. The successful application of sealing technology with pressure can improve the construction quality and efficiency, reduce the construction risk and ensure the stability of the project.

The basic principle of a pressure seal forms a closed water barrier by installing a rubber or similar material seal at a certain location. The seal can be a rubber plug, a rubber washer or an expansion rubber tube. When the construction needs to be expanded with pressure sealing, it is first necessary to select suitable seals and install them in the corresponding position of the pipeline or wellbore. Then, by injecting air or water pressure into the seal to expand it, creating an effective sealing effect.

Pressure plugging technology has a wide range of applications. It can be used to prevent groundwater from entering subways, tunnels, basements or underground engineering construction sites, thereby keeping the work area relatively dry. In the down-hole mining industry, tape sealing can be used to control the pressure in the wellbore and prevent the flow of geological gas or water out of the wellbore to ensure the stability of the downhole operator. In addition, pressure plugging can also be used for testing, maintenance and plugging in pipeline construction. Whether it is cement pipeline, oil pipeline or natural gas pipeline, the pressure and stability of the pipeline can be controlled and maintained through pressure sealing technology.

There are some key points to note when performing a pressure plug. First of all, it is very important to choose the right seal. The material, size and pressure bearing capacity of the seal directly affect the sealing effect. Secondly, construction personnel need to be familiar with the operating process and precautions to ensure stability and effectiveness during the plugging process. In addition, necessary inspections and inspections should be carried out before construction to ensure the integrity and stability of the pipeline or wellbore.

All in all, pressure plugging technology is an important technology, which plays an important role in underground engineering, underground mining and pipeline construction. It can protect the dryness and stability of the construction site and improve the quality and efficiency of the project. With the continuous development of science and technology, pressure sealing technology is also constantly innovative and improved, providing more reliable and efficient solutions for engineering construction.
