Sewage pipeline plugging system suitable for high-water-level operation and use method

Abstract

The invention relates to a sewage pipeline plugging system suitable for high-water-level operation and a use method. According to the technical scheme, the system comprises a desilting device used for cleaning an inlet of a sewage pipeline, an air bag plugging device and an air bag mounting device. The air bag plugging device is provided with an air bag and used for plugging a sewage pipeline inlet cleaned by the desilting device through the air bag; the air bag mounting device is used for remotely mounting the air bag to the part of the sewage pipeline inlet; and the air bag mounting device is provided with a vertical telescopic mechanism, the lower end of the vertical telescopic mechanism is connected with two parallel transverse rods perpendicular to the axial direction of the vertical telescopic mechanism, the distance between the two transverse rods is matched with the diameter of a sewage pipeline, a pulley I is mounted at the outer end of each transverse rod, and a pulley II is mounted at the inner end of each transverse rod. The air bag is arranged between the two transverse rods of the air bag mounting device and connected with two traction ropes, and the two traction ropes are sequentially wound around the pulleys I and the pulleys II on the transverse rods on the two sides respectively and then extend upwards along the vertical telescopic mechanism to be connected with a traction mechanism. The plugging system is suitable for the technical field of municipal sewage pipeline plugging.

Description

technical field [0001] The invention relates to a sewage pipeline plugging system suitable for high water level operation and a usage method. The utility model is applicable to the technical field of municipal sewage pipe plugging. Background technique [0002] During the long-term operation of urban sewage pipelines, a large amount of garbage floating matter and silt may accumulate in the pipelines, which will affect the normal operation of the pipelines, and even structural defects may occur in the pipelines due to the long-term corrosion of sewage in the pipelines. When the above situation occurs, the pipeline needs to be desilted or repaired, and the preparatory work for the above project needs to be blocked upstream of the pipeline, and the sewage is pumped to the second sewage inspection well downstream. [0003] At present, there are two ways to block sewage pipes: the first is to use bricks, and cement bricks are used to block the mouth of the sewage pipes; the seco...

Problems solved by technology

[0004] There are defects in the above two existing methods: (1) bricks cannot be used for secondary use when bricks are used for plugging, and the removal is difficult and may not be completely removed, resulting in re-silting in the pipeline; (2) bricks Block plugging is more difficult when the water level is high, and the cement is difficult to solidify quickly, resulting in incomplete plugging; (3) Although the air bag plugging can realize secondary utilization, the air bag requires people to enter the inspection well and insert it into the sewage pipe , In actual operation, there have been safety accidents in which the air bag was stunned during the high-pressure inflation process; (4) The water level in the sewage main pipe is relatively high, and no matter whether the air bag or brick is used to block it, people need to enter the inspection well. , there are many toxic substances in the sewage, and there may be a large amount of hydrogen sulfide gas in the well, which poses a serious threat to personal safety
