At present, different gate types are formed by plates, beams and columns (arc steel gates), and the plates and the beams (plane steel gates and herringbone gates) are connected through welding and bolts. Welding is the most common connecting method applied to hydraulic steel structures, and has the main advantages that the section of a steel member is not weakened, and splicing plates are not needed; the welded structure has simple structure, convenient manufacture and processing and good sealing performance; the main defects are that high temperature is generated locally during welding, the material performance of a heat affected zone is reduced and the material is not shrunk uniformly, the residual stress and the residual deformation of a welding structure are easy to cause, the welding quality is not easy to check, cracks are prone to being generated, and the tiny cracks often cause brittle failure or fatigue failure in the working process of a hydraulic steel gate. The bolt connection has the advantages of simple operation, convenient disassembly and easy inspection and guarantee of connection quality, but has the obvious defects that holes need to be drilled in the connecting components, the drilled holes damage the integrity of the components, stress concentration is easy to cause, and finally the fatigue failure of the components is caused.
