Abstract

Technical Field
[0001] The utility model relates to the technical field of engineering construction, in particular to an ultra-deep two-stage energy dissipation well. Background Art
[0002] Energy dissipation wells are one of the important facilities in the municipal pipe network system. Their main function is to reduce the kinetic energy of water flow, dissipate the energy of incoming water at a higher elevation upstream, and then discharge it into the lower elevation downstream, thereby reducing damage to downstream pipes and structures.
[0003] Most energy dissipation wells drop water to the bottom of the well, and achieve the purpose of energy dissipation through direct collision between the water flow and the bottom of the well. This is only applicable to the case of a low drop height. If the drop is too deep, the hydraulic impact of this energy dissipation is too large, which is easy to cause scouring of the well wall and pipeline. If the kinetic energy of these water flows is not eliminated, it will cause harm to downstream facilities, affect the safe and reliable operation of the pipeline, and cause serious problems. Generally, ultra-deep energy dissipation wells refer to energy dissipation wells with a depth of 6.6 meters or more. Utility Model Content
