Step type drainage tunnel and energy dissipation method
The invention relates to the technical field of water conservancy and hydropower engineering, in particular to a stepped drainage tunnel and an energy dissipation method. The step type drainage tunnel comprises a tunnel body and an energy dissipation building, the energy dissipation building comprises multiple stages of energy dissipation steps which are continuously connected, each energy dissipation step comprises a first step surface and a first slope surface, and the first slope surface of the upper-stage energy dissipation step and the first step surface of the lower-stage energy dissipation step are connected and form a first scouring concave angle larger than 90 degrees. Water flow can be gradually decelerated when passing through the multi-stage energy dissipation steps, carried particles such as silt are guided through the first slope face, the situation that the particles such as the silt are permanently deposited between every two adjacent energy dissipation steps can be prevented through the first scouring concave angle, and therefore the energy dissipation effect is achieved while the energy dissipation effect is achieved. Sediment is prevented from being deposited on the energy dissipation step, the collision and abrasion degree of sediment particles to the energy dissipation step is reduced, the service life of a building is prolonged, and the maintenance cost is reduced.
本发明涉及水利与水电工程技术领域，具体涉及一种台阶式泄水隧洞及消能方法。台阶式泄水隧洞包括洞体和消能建筑物，消能建筑物包括连续衔接的多级消能台阶，消能台阶包括第一台阶面和第一斜坡面，上一级消能台阶的第一斜坡面和下一级消能台阶的第一台阶面衔接并形成角度大于90°的第一冲刷凹角。本发明利用多级消能台阶使水流通过时能够逐渐减速，并利用第一斜坡面对携带的泥沙等颗粒物进行导流，通过第一冲刷凹角可以防止相邻的两个消能台阶之间存在泥沙等颗粒物永久淤积的凹角，从而在满足消能作用的同时，防止泥沙在消能台阶上淤积，减轻了泥沙颗粒对消能台阶的碰撞和磨损程度，以增长建筑物的使用寿命，降低维护成本。
