SonLa水电站超大型潜孔弧形闸门布置形式研究
Research on the Layout Pattern of the Super Scale Submerged Orifice Radial Gate of SonLa Hydropower Station
摘要
Abstract
SonLa hydropower station is by far the largest hydropower station in Vietnam, also in Southeast Asia. Its spillway submerged orifice radial gate belongs to the range of the super ones, whose design, manufacture and installation are with difficulty. Based on the research of domestic and international super radial gate data, through comparative analysis of the key technical indicators and parame-ters of the project, including the orifice size, the maximum head pressure, main frame structure section, and hinge load, etc. , accord-ing to the operation requirements and previous problems occurring to submerged orifice radial gate, a new type of layout is applied to this gate and hoist. The new welding form used refreshes the relevant domestic record on sealing installation measures to improve the accuracy requirements. To ensure the installation accuracy, research analysis and engineering practice were carried out by using new construction technology and new material on the installation of embedded parts of the hinge, unconventional hanging point support and anti-jamming measures form according to the engineering characteristics of super wide. We analyzed and evaluated the structure layout by using three-dimensional finite element analysis software ANSYS and the analytical method. We also verified the rationality of the structure layout by comparing five kinds of load combination conditions to determine the retaining water and lifting door as the working condition of control and obtain the stress and deflection of each component being less than the standard value,which provides new de-sign ideas and accumulates experiences for the selection of China's super scale submerged orifice radial gate layout.关键词
