Abstract

The invention relates to an assembled bridge pier foundation, which comprises: a pier main body; a protective part, which is installed on the front side of the main pier body along the water flow direction, the protective part has a top surface and a bottom surface oppositely arranged, and connects the The inner edge of the top surface is in contact with the inner surface of the inner edge of the bottom surface, and the inner surface is attached to the outer surface of the main body of the pier. The protective part also includes an outer surface for diffusing and weakening the submerged flow. The outer surface The side faces connect the outer edge of the top surface and the outer edge of the bottom surface, and the outer edge of the top surface is closer to the pier body than the outer edge of the bottom surface. The invention relates to an assembled bridge pier foundation, which can suppress the development of the horseshoe vortex system around the main body of the pier by diffusing and weakening the submerged flow, thereby reducing local scour; Partially prefabricated for protection against unscoured or scoured shallow pier bodies.

Description

technical field [0001] The invention relates to the technical field of partial scour protection of bridge foundations, in particular to an assembled bridge pier foundation. Background technique [0002] At present, when a bridge is built in a natural river, due to its water blocking effect, the local scour caused by the horseshoe vortex system formed around the bridge pier is related to the structural safety and normal operation of the bridge. As the main reason for the formation of the horseshoe vortex in front of the pier, the subsurface current is closely related to the local scour degree of the pier. Therefore, how to weaken or eliminate the submerged flow in front of the pier is one of the important means of pier protection. [0003] In related technologies, protective measures such as retaining ring and enlarged foundation all utilize the mechanism of weakening or eliminating the submerged flow in front of the pier to reduce local scour of the pier. For retainer prot...
