Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] refer to figure 1 , is a reinforcement component of a deep-water bridge pile foundation disclosed by the present invention, including a locking ring sleeved on the side wall of the pile foundation 1, a fixing ring 2 located below the locking ring, and a plurality of anchor rods 25, and the fixing ring 2 is arranged horizontally , a plurality of anchor rods 25 are evenly welded to the bottom surface of the fixing ring 2 circumferentially along the vertical direction. Simultaneously, the end of the anchor rod 25 inserted into the foundation is conical, and the side wall of the anchor rod 25 is fixedly provided with several barbs 26 in the circumferential direction. sloping on one side. The J-shaped barb 26 is conducive to enhancing the prestress applied on the anchor rod 25. The barb 26 is hooked inside the foundation, so that the anchor rod 25 is not ...

Abstract

The invention relates to the technical field of bridge construction, in particular to a bridge deepwater pile foundation reinforcing component. The bridge deepwater pile foundation reinforcing component is technically characterized by comprising a locking ring, a fixing ring and anchor rods, wherein the locking ring is formed by splicing two U-shaped blocks, the top face of the fixing ring is connected with two abutting rod sets, the two U-shaped blocks and the two abutting rod sets are arranged in a one-to-one correspondence mode, each abutting rod set comprises two abutting rods distributedat an interval, one end of each abutting rod is hinged to the top face of the fixing ring, elastic pieces are fixedly connected between each U-shaped block and the free ends of the corresponding two abutting rods, the free end of each abutting rod is fixedly provided with an abutting block and a triggering block, the abutting blocks abut against the side wall of the pile foundation, two triggeringrods corresponding to the corresponding two abutting blocks movably penetrate through each U-shaped block, the triggering rods move up and down to abut against the triggering blocks, and each U-shaped block is provided with a driving assembly. The component can play a good role in supporting and fixing the pile foundation, and therefore the overall stability of the pile foundation is improved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, and more specifically, the invention relates to a reinforcing component of a deep-water pile foundation of a bridge. Background technique [0002] The bridge foundation is the lowest part of the bridge structure directly in contact with the foundation, and is an important part of the bridge substructure. The part of the formation that bears the load from the foundation is called the foundation. After the foundation and foundation are subjected to various loads, they will produce stress and deformation. In order to ensure the normal use and safety of the bridge, the foundation and foundation must have sufficient strength and stability, and the deformation should also be within the allowable range. With the development of the economy and transportation, highway bridges are constantly being built. The pile foundation of the highway bridge is the foundation of the entire highway bridge. ...
