The operation process of the sewage well plugging construction team
1. Preparations.
1.Understand the site situation: After the construction team arrives at the site, they must first have a detailed understanding of the location, shape, size, depth and surrounding environment of the sewage well, so as to prepare for the subsequent construction.
2.Equipment preparation: According to the site conditions and construction requirements, prepare the corresponding plugging equipment and materials, such as submersible pumps, submersible plugging devices, airbags, etc.
2. Blocking operation.
1.Wellhead plugging: put the airbag into the wellhead, inject gas to compact the airbag, and then use cement to wipe the surface to plug. Pay attention to leave a vent to ensure the safety of construction.
2.Underground operation: connect the submersible pump and the pumping pipe, put the sewage pump into the downhole, start the pump to discharge the underground sewage, and at the same time the construction personnel enter the underground for plugging operations.
3.Pipeline plugging: seal at the pipe interface, use a submersible pump and pumping tape for drainage, and pay attention to maintaining the normal operation of the pumping equipment.
3. Demolition operation.
1.Construction sequence: first carry out the uphole operation, and then carry out the downhole operation. Drainage treatment is carried out first, and then demolition work is carried out.
2.Demolition method: Use a cutting machine to cut the plugging material into small pieces, and then use lifting equipment to lift it out of the well for processing. Pay attention to ensure the safety of the construction site and avoid accidents.
4. Precautions.
1.The construction personnel must be professionally trained and familiar with the construction process and safe operation procedures.
2.The construction site must be well ventilated to avoid poisoning and suffocation accidents.
3.The equipment must be inspected and maintained before construction to ensure the normal operation of the equipment.
4.When carrying out plugging and demolition operations, it is necessary to pay attention to the impact of the surrounding environment and residents' lives, and comply with relevant regulations and requirements.
In short, the sewage well plugging construction is an important construction project, which requires the construction team to carry out the construction in strict accordance with the operation process and precautions to ensure the quality and safety of the construction. At the same time, it is also necessary to pay attention to protecting the environment and reducing the impact on the surrounding residents.
