Studying On Of Prestressed Pier Used Steel Reinforced Concrete Anchorage Of Radial Gate Support Structure

Gate is one of the most common hydraulic structures used to control water flow adjustment. Generally, the smaller span of the gate is often used in reinforced concrete pier, but for large span, retaining a high degree of high gate, its thrust greater use of ordinary reinforced concrete structure of radial gate support of the pier there Local pier difficult to control the tensile cracking, radial gate support bracket bulky, heavy structure, poor seismic performance of outstanding problems. Therefore, technology can be applied to large-scale prestressed concrete pier radial gate structure:the bearing and bearing joints and the local pier prestressed tension zone to offset the thrust generated by radial gate tensile stress, thus ensuring structure to meet the carrying capacity and the normal requirements.Prestressed concrete pier structures currently at home and abroad has been widely used, but there are also many disadvantages. In previous studies, based on the characteristics for LiuJia Controlling gate works, this study proposes a new structure -- steel reinforced concrete anchorage of radial gate support structure of prestressed pier. Transmission of the structure clear and good mechanical condition, solve the radial gate support and the binding site and the pier pier local tensile zone of concrete cracking problems, and has a small size, seismic performance, and effectively improve the flow conditions, steel box body can be industrially arc hinge bolt seat positioning accuracy, ease of installation, coaxial gate high, safe and reliable operation, convenient construction, short construction period, less investment.
