Pile column type concrete hollow pile pier structure

Abstract

The invention relates to a pile column type concrete hollow pile pier structure. The pile column type concrete hollow pile pier structure is characterized by comprising a concrete hollow pile pier, a bridge support, a pier cover beam and a base bearing platform, a flange disc is arranged at the lower end of the concrete hollow pile pier, a reserved bolt hole is formed in the flange disc, the flange disc is connected with the base bearing platform, the flange disc and the base bearing platform are arranged in cast-in-place concrete, an upper bridge support steel plate is arranged at the upper surface of the bridge support while a lower bridge support steel plate is arranged at the lower surface of the bridge support, a flange disc is arranged at the upper end of the concrete hollow pile pier and connected with the lower bridge support steel plate, and the upper bridge support steel plate is connected with the pier cover beam. The pile column type concrete hollow pile pier structure has beneficial effects that the concrete hollow pile pier can be prefabricated in a factory, the pier length can be controlled precisely, the bearing ability of the pier is improved, the concrete hollow pile pier is connected with the base bearing platform through using the flange discs and an insert core reinforcing cage and casting concrete in place, the connecting intensity of the pier can be guaranteed, and the stability thereof is improved.

Description

technical field [0001] The invention belongs to bridge pier structures, in particular to a pile-column concrete hollow pile bridge pier structure. Background technique [0002] Bridges are buildings erected on rivers, lakes, seas, valleys or traffic routes to allow vehicles and pedestrians to pass smoothly. A bridge is generally composed of a superstructure, a substructure and ancillary structures. The superstructure includes a bridge span structure and a bearing system. The substructure includes abutments, piers and foundations. [0003] The pier structure is mainly composed of three parts: pier cap, pier body and foundation. According to different construction methods, it can be divided into two categories: gravity pier and light pier. Light pier can be divided into hollow pier, frame pier, thin-walled pier and pile Pillar piers [0004] Gravity bridge piers: Generally, they are solid structures made of concrete or stone masonry, which are characterized by making full us...
