AI Technical Summary

Technical Problem

In traditional bridge construction, the increased number of steel pipe piles leads to higher construction costs, greater complexity, and longer construction periods, making it difficult to efficiently transfer loads and ensure structural stability.

Method used

The design adopts a combination of primary and secondary connecting piers, and optimizes the load distribution through structures such as transfer beams, connecting steel pipes, horizontal bracing and crossbeams, thereby reducing the number of steel pipe piles driven into the ground and improving the bearing capacity and torsional rigidity.

Benefits of technology

It achieves efficient load transfer and distribution, reduces construction costs, improves construction efficiency and structural safety and reliability, and enhances torsional rigidity and load-bearing capacity under complex working conditions.

Abstract

The utility model relates to a bridge pushing buttress linking device. The bridge pushing buttress linking device comprises a first-stage linking buttress and a second-stage linking buttress. The first-level chaining buttress is provided with two sets of first-level steel pipe piles buried into soil, one set of first-level steel pipe piles comprises at least three first-level steel pipe piles, every two adjacent first-level steel pipe piles are connected in a parallel connection mode, transfer beams are arranged at the tops of one set of first-level steel pipe piles, and a connecting steel pipe is arranged between every two transfer beams. The second-level linkage buttress is arranged above the first-level linkage buttress, two sets of second-level steel pipe piles corresponding to the two transfer beams and arranged on the corresponding transfer beams are arranged, one set of second-level steel pipe piles comprises at least two second-level steel pipe piles, parallel connection is arranged between every two adjacent second-level steel pipe piles, and a cross beam is arranged at the top of one set of second-level steel pipe piles. Through the up-and-down combination design of the first-stage chaining buttress and the second-stage chaining buttress, efficient transmission and distribution of loads are achieved, the number of buried steel pipe piles is reduced, and the construction cost is reduced.
