Problems solved by technology

Existing energy dissipators often only consider the energy dissipation of water flow, while ignoring the deposition of suspended solids in the energy dissipation section. Stilling well energy dissipators often require high-frequency manual or manual work in transportation systems with high sediment content. Mechanical dredging, otherwise the energy dissipation effect will be lost due to the deposition of suspended solids; although the stilling sill type energy dissipation device can play an energy dissipation effect, the ga

Abstract

The invention discloses an energy dissipater in wading engineering, comprising an upstream water delivery structure, a hydraulic drop structure, a flow control structure and a downstream water delivery structure. The upstream water delivery structure is connected with the downstream water delivery structure through the hydraulic drop structure; the protruding flow control structure is arranged at a downstream end of a connection section of the hydraulic drop structure and the downstream water delivery structure, and a number of limber holes are arranged on the flow control structure. The energy dissipater in the wading engineering provided by the invention is the energy dissipater which can realize a good energy dissipating effect and can avoid sediments silting up in a working section and enable gas mixed in water to smoothly overflow.

Description

technical field [0001] The invention relates to the technical field of energy dissipation facilities in water-wading engineering, in particular to an energy-dissipating device in water-wading engineering. Background technique [0002] In urban drainage and waterlogging prevention, water conservancy projects and related engineering fields, it is often necessary to carry out long-distance water delivery with large drops. It has a strong impact on the downstream structures. Therefore, in related projects, different forms of energy dissipators are used to dissipate the energy of the upstream water, so as to reduce the impact and damage of the downstream structures due to the impact of water flow. [0003] The existing types of energy dissipators include: bottom flow energy dissipator, deflecting flow energy dissipator, surface flow energy dissipator, bucket energy dissipator, along-way energy dissipator, free-fall energy dissipator, wide tail pier energy dissipator And the ener...
