Bridge pile foundation structure and construction method thereof

Abstract

The invention discloses a bridge pile foundation structure. The bridge pile foundation structure comprises a riverbed, a bridge pile foundation and a reinforcing structure, wherein the bridge pile foundation is vertically arranged on the riverbed; a fixing base plate is of an annular structure; the circle center of the fixing base plate is located in the center of the bridge pile foundation; eightsets of second fixing plates are arranged on the top face of the fixing base plate; the reinforcing structure is arranged on the outer wall of the bridge pile foundation, and the bridge pile foundation is connected with the second fixing plates on the fixing base plate through the reinforcing structure; a first fixing semi-ring is connected with a second fixing semi-ring through a telescopic plate; two sets of first telescopic rods are symmetrically arranged on the arc-shaped outer wall of the first fixing semi-ring and movably connected with one ends of the first telescopic rods; and two sets of second telescopic rods are symmetrically arranged on the arc-shaped outer wall of the second fixing semi-ring and movably connected with one ends of the second telescopic rods. According to the bridge pile foundation structure, the fixing and reinforcing position can be adjusted according to the height of the bridge pile foundation, the optimal fixing position is selected, operation is convenient, and firmness is good.

Description

technical field [0001] The invention belongs to the technical field of bridges, and relates to a bridge pile foundation structure, in particular to a bridge pile foundation structure and a construction method thereof. Background technique [0002] With the development of economic construction, there are more and more deep-water bridge projects. As the most important foundation type in bridge engineering, bridge pile foundation is widely used. [0003] In the prior art, the reinforcing device usually fixes the fixed and reinforced positions of the bridge pile foundations and is not easy to adjust, resulting in the problems that it is not suitable for reinforcing different bridge pile foundations and cannot find the best reinforcement position; During the installation process of the reinforcement structure, many groups of bolts need to be matched for work, and the fastening work of these bolts consumes a lot of manpower and material resources; in addition, the setting of the r...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that in the prior art, the reinforcing device usually fixes the fixed and reinforced positions of the bridge pile foundations, and it is not easy to adjust, so it is not suitable for reinforcing different bridge pile foundations and cannot be found. The problem of the best reinforcement position; during the installation process of the reinforcement structure, many groups of bolts need to be matched for work, and the fastening work of these bolts is a problem that consumes manpower and material resources extremely; in addition, the reinforcement structure in the present invention The setting solves the problem that in the prior art, due to the influence of water flow near the bridge pile foundation, the hydrodynamic characteristics near the pile foundation are complex, and the scouring effect of the water flow on the bridge pile foundation is formed. The stability of the action is reduced, which in turn destroys the structure of the bridge pile foundation, causing potential safety hazards for the entire bridge. There are two main types of common bridge pile foundation diseases. In order to solve the problem of insufficient pile section strength caused by defects, a bridge pile foundation structure and its construction method are proposed
