Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hydraulic engineering, in particular to a fabricated steel gate for hydraulic engineering and a design method thereof. BACKGROUND

[0002] The steel gate for hydraulic engineering is an important flow regulating device in the water conservancy and hydropower engineering, and plays an important role in flood control, power generation, navigation and water resource allocation. The safety and stability of the steel gate for hydraulic engineering largely determine the safety and benefit of the entire water conservancy and hydropower engineering, and the safety of the life and property of the people downstream. Therefore, it is very important and necessary to ensure the safety and stability of the steel gate for hydraulic engineering.

[0003] The commonly used steel gate for hydraulic engineering in the water conservancy and hydropower engineering mainly includes an arc-shaped steel gate, a plane steel gate and a miter gate. At present, different types of gates are formed by welding and bolt connection of plates, beams and columns (for the arc-shaped steel gate), plates and beams (for the plane steel gate and the miter gate). The welding is the most commonly used connection method in the steel structure for hydraulic engineering, and has the advantages of not weakening the cross section of the steel member, not needing splicing plates, simple structure, convenient manufacturing and processing, and good sealing performance. However, the welding has the disadvantages of high temperature in the local area during the welding, which causes the reduction and uneven shrinkage of the material performance in the heat affected zone, and easily leads to the residual stress and residual deformation of the welded structure, and the welding quality is not easy to check, which often leads to cracks, and the small cracks often lead to brittle failure or fatigue failure in the operation of the steel gate for hydraulic engineering. The bolt connection has the advantages of simple operation, convenient disassembly, easy checking and guaranteeing of the connection quality, but has the obvious disadvantage of needing to drill holes on the connecting members, which destroys the integrity of the members and easily leads to stress concentration and finally leads to fatigue failure of the members. In view of the above problems existing in the prior art, it is urgent to provide a fabricated steel gate for hydraulic engineering and a design method thereof which avoid welding and bolt connection.
