Abstract

The invention relates to the technical field of bridge substructure construction, in particular to a jacket positioning device, which includes: a guide frame, at least one lock female head, a lock male head, a vertical anti-collision bracket and a frontal anti-collision mechanism. Among them, the guide frame is set on one side of the jacket; at least one locking female head is arranged on the other side of the guide frame; each locking female head matches a locking male head, and the locking female head is arranged on the jacket to be connected One side; each lock female head is correspondingly provided with a vertical anti-collision bracket. The jacket collides with the female end of the lock from above; each female end of the lock is correspondingly equipped with a frontal anti-collision mechanism, which is sleeved on the outside of the female end of the lock and connected with the guide frame to prevent the jacket to be connected Hit the female end of the lock from the horizontal direction. It can effectively solve the problem in the prior art that the lowering of the jacket easily causes collision damage during the lowering process.

Description

technical field [0001] The invention relates to the technical field of bridge substructure construction, in particular to a jacket positioning device. Background technique [0002] When constructing the substructure of a bridge in a marine environment, the supporting piles of the drilling platform are usually inserted directly by a piling barge. This scheme requires that the supporting piles can be self-stabilized under the action of waves and surges. [0003] In the prior art, for deep-water areas with no overburden or shallow overburden, when directly inserting support piles cannot be self-stabilized, the platform solution of jacket + support columns is often used. The jacket is manufactured in several units in the factory and assembled into a whole. After the assembly is completed, it is disassembled and transported to the site, and then separately hoisted and lowered by a floating crane. When lowering, it is necessary to install prisms on the four corner piles of each u...
