There are many types of pipeline construction and dredging maintenance blocking in municipal engineering, such as underwater wall blocking, steel plate blocking, dry mix blocking, concrete mold bag blocking and so on. The principle of pipeline sealing is based on the actual pipeline conditions and the strength of the water flow in the pipe. In order to avoid the water pressure caused by the upstream water flow after the sealing time is too long, the water pressure generated by the upstream water flow is a certain threat to the downstream construction personnel, so the sealing distance is determined according to the actual situation, and the upstream water inlet and the intersection well are blocked first.

Technical characteristics and scope of application 1.1 Technical characteristics (1) Safety: good sealing performance, can effectively control the anti-seepage requirements of the pipeline, ensure the safety of the operation of the working surface personnel, and improve the construction quality. (2) Construction period: the construction speed is fast, regardless of the diameter of the pipeline, the installation is extremely convenient and fast, and the blocking of a pipe entrance only takes 2h, which greatly saves labor and construction costs. (3) Economy: simple operation, high work efficiency and controllable quality; Strong applicability, less manpower and material resources required, shorten the plugging time, and directly reduce the construction cost. (4) Environmental protection: the air bag does not deform, is not easy to age, can be reused many times, save construction cost, energy saving and environmental protection. 1.2 Scope of application The applicability of this technology is very wide, within the range of pressure allowed, the air bag can play a thorough section sealing effect on various materials, specifications and pipe diameters of the pipeline; It is also suitable for quickly blocking water flow in pipelines of different diameters, different planes and positions, and is an ideal tool for underground pipelines to carry out drainage and silt treatment.
