The fetter technology with pressure sealing is a common technical means in engineering construction, which is used for temporary sealing in pipelines, shafts and other facilities. The sealing and control of the pipeline can be realized effectively through the injection of the fetter material and the regulation of the pressure.

The structure of bonding technology mainly includes the following aspects: bonding materials, bonding equipment, construction technology, construction steps and stability measures.

1. Binding materials:

The bond material is the key to the sealing. Common bonding materials are cement, cement, adhesive, adhesive paste, epoxy resin and so on. Different projects need to choose suitable bonding materials to ensure the sealing effect.

2. Attachment equipment:

The holding equipment includes grouting equipment, pressure device, pipe connection, control system, etc. The grouting equipment is mainly used to inject the bond material into the pipeline or wellbore, the pressure device is used to control the injected pressure, the pipeline connector is used to connect the bond material and the pipeline, and the control system is used to monitor and control the entire construction process.

3. Construction technology:

Construction technology refers to the process and steps of the whole bonding process. It generally includes preparation work, pretreatment, grouting construction, curing process, etc. Preparation work includes checking equipment and materials for integrity, cleaning work areas, etc. Pretreatment is to improve the sealing effect, the common pretreatment methods include cleaning pipes, repairing damaged parts and so on. Grouting construction is to use grouting equipment to inject the bond material into the pipeline or shaft, and control the injection pressure. The curing process is to wait for the holding material to solidify into a hard sealer in the pipe.

4. Construction steps:

The specific construction steps vary according to different projects, but generally include the following steps: preparation, pretreatment, grouting construction, curing inspection and follow-up treatment. In the preparation work, it is necessary to check and prepare the required materials and equipment; Pretreatment includes cleaning pipes and repairing damaged parts; Grouting construction is to inject the binding material into the pipe or shaft; Solidification test is to wait for the binding material to solidify, and test to confirm the sealing effect; Follow-up treatment includes cleaning the construction area and equipment, as well as recording and reporting on the construction.

5. Safety measures:

In the construction of the bonding process, stability is of Paramount importance. It is necessary to formulate a construction plan, clarify the construction process and operating procedures, equip technical personnel to carry out construction, and take corresponding stabilization measures, such as wearing personal protective equipment, setting warning signs, maintaining ventilation, etc.

In short, the binding process with pressure sealing is a complex and important construction technology, which plays an important role in the construction and maintenance of pipeline, wellbore and other facilities. The blockage and control of the pipeline can be realized effectively by mastering the structure and construction steps of the fetter process, selecting the fetter materials and equipment reasonably, and taking the necessary stabilization measures to ensure the stability and quality of the construction.
