Construction of sealing for municipal sewage pipeline network, with a diameter of 1000MM; no leakage is required. During the sealing period, Party A agrees to cooperate and suspend pumping from the pump station

1. Ensure that the water flow in the pipeline is in a static state during construction;

2. Block the entrance and exit by no less than 800mm (ensuring basic access for construction personnel);

3. On site equipment is sufficient to provide the necessary materials for sealing (including red bricks, high-grade cement, non dispersing agents for concrete, auxiliary tools, etc.).

Main construction plans and measures for the project:

Based on the above situation, our company has arranged underwater sealing construction for this project, with targeted construction. In the short term, airbag sealing (within a water depth of 3 meters; convenient for short-term construction and low pressure bearing) and brick sealing (240mm wall within a water depth of 5 meters) are generally used for sealing; 370MM wall at a depth of 8 meters; 500mm wall beyond a depth of 10 meters; It has safety and reliability! ）According to your company's requirements and the on-site situation, we will adopt a brick reinforced sealing construction plan (500MM wall sealing construction).

Provide underwater engineering services such as plugging, salvaging, installation, cutting, dismantling, plugging, welding, dredging, filming, testing, and exploration. Since its establishment, the company has undertaken many difficult projects, with a rigorous safety organization, quality assurance system, and strict safety measures. It has gained the trust of many property owners and enterprises for its high quality, fast speed, and reputation.

Airbag underwater sealing: Without water flow, there is no incoming water in the upstream of the pipeline, and the water level does not change after sealing. Airbag sealing can be used due to its construction characteristics, fast speed, and easy removal. It is recommended to use temporary sealing within 5 hours.

Steel plate underwater sealing: It can be used when the water flow in the pipeline is fast. Steel plate sealing can be installed underwater. Steel plate sealing needs to be customized with steel plate modules according to the actual situation under the well chamber. The reliability of steel plate sealing is the same as that of wall sealing, and it also needs to be dismantled by frogmen underwater. After steel plate sealing, there will be a small amount of water leakage.

Underwater wall sealing: There is incoming water upstream of the pipeline, and the water level will continue to rise after sealing. The service life of pipeline sealing is relatively long, and underwater wall sealing can be used. The construction characteristics are that the construction period is longer than that of airbag sealing, requiring a 12 hour solidification period. Demolition requires frogmen to break it underwater. The advantage of sealing is high reliability, which ensures the safety of underground personnel operations and is the preferred long-term sealing method.
