Description

Mud-blocking sand-blocking water-passing anti-floating device for water conveying pipeline Technical Field The utility model relates to the technical field of hydraulic engineering equipment, in particular to a mud-blocking, sand-blocking and water-passing anti-floating device for a water conveying pipeline, which is suitable for flood protection of the water conveying pipeline in a rainy region. Background The traditional pipeline protection measures mostly adopt a single gravity ballast or a simple filter screen structure, and have obvious defects when dealing with sediment inflow and buoyancy unbalance caused by high-intensity rainfall, on one hand, the conventional filter screen has a large aperture (usually more than 20 mm), can only intercept large-particle impurities, has insufficient retention rate on suspended sediment with the particle size of less than 0.1mm, and leads to the acceleration of the pipeline sedimentation rate, and on the other hand, the traditional weighting mode relies on a concrete balancing weight, so that the problems of long construction period, high cost, weak impact resistance and the like exist.
