Problems solved by technology

Once the flood exceeds the standard, the water blocking effect of traditional gate piers or bridge piers will be greatly increased, which will intensify the flow around the pier and the scour around the pier. When the scour is severe, the foundation near the pier will be damaged, which may cause the project to lose stability. sex accident
Therefore, traditional gate piers or bridge piers cannot guarantee the actual safe operation of the project, and it is necessary to improve them

Abstract

The split gate or bridge pier provided by the present invention is an improvement on the basis of traditional gate piers or bridge piers, and is divided into three types: longitudinal split type, transverse split type and cross split type. The longitudinal slotted gate or bridge pier is composed of a pier body, which has a top surface, a bottom surface, an upstream end surface, a downstream end surface, a front side, and a rear side. The centerline of the top surface, the upstream end surface and the downstream end surface of the pier body coincides with the longitudinal centerline of the pier body. The difference between the transverse split type and cross split type pier or bridge pier structure and the longitudinal split type pier or bridge pier structure is that the splits set on the pier body are respectively transverse splits and cross splits. The split gate pier or bridge pier provided by the present invention can further reduce the resistance of water flow from the gate pier or bridge pier, increase the discharge capacity of the water-passing structure, and reduce the risk of engineering accidents.

Description

technical field [0001] The invention belongs to the field of flood discharge and energy dissipation facilities used in water conservancy and hydropower projects, and particularly relates to gate piers and bridge piers of water retaining structures which are used in low Floyd numbers and large single-width flow rates. Background technique [0002] The unreasonable design of gate piers or bridge piers will increase the resistance of the water-passing structures to the water flow, reduce the discharge capacity of the water-discharging structures, and even cause bad hydraulic phenomena such as stagnant water in front of the pier and water fins behind the pier. Exacerbating the erosion of the pier foundation may cause damage to the supporting foundation and lead to engineering wrecks. [0003] The traditional gate pier or bridge pier has a full solid structure. The upstream end of the pier body is usually semicircular or elliptical, and the downstream end is usually a streamline ...
