AI Technical Summary

Technical Problem

Existing technologies cannot meet the high requirements for pile driving accuracy in the construction of steel pipe pile foundations for offshore bridge piers, especially in complex sea conditions, which makes it impossible to achieve precise and safe construction, leading to project stagnation.

Method used

The platform adopts a detachable base-type multi-pile guiding and positioning stabilizing platform, which includes a base support frame, positioning steel piles, a primary sliding bearing frame, a secondary sliding pile driving operation platform, and a suspension leveling device. Combined with a GPS antenna and a total station, it achieves three-level correction control. With modular design and an external lifting and lowering system, it enables rapid assembly and disassembly of the platform and high-precision pile driving.

Benefits of technology

It achieved high-precision control of the horizontal position deviation of steel pipe piles after pile driving to less than 33.75mm and the verticality to less than 2‰, which reduced construction costs, improved equipment utilization and construction efficiency, and eliminated quality risks.

Abstract

The invention discloses a detachable base type multi-pile guiding and positioning pile stabilizing platform and a pile sinking construction method thereof. The platform comprises a seat bottom supporting frame, and the seat bottom supporting frame is located on a seabed. The positioning steel pile is driven into a seabed and is connected and leveled with the support frame through a suspension device; the primary sliding frame can longitudinally slide along the support frame to rectify deviation; the secondary sliding operation platform is matched with the sliding rail of the primary frame through a guide rotating mechanism at the bottom of the secondary sliding operation platform, transverse sliding and azimuth angle rotation can be achieved, transverse and angle deviation correction can be conducted, and a guide hole and a pushing piece used for fine adjustment of a pile body are arranged on the secondary sliding operation platform. The invention further discloses a three-stage deviation rectification pile sinking method based on the platform. By means of the structure and the method, the problem that offshore pile group sinking precision is insufficient under the complex sea condition is effectively solved, centimeter-level high-precision pile sinking is achieved, the platform has the advantages of being detachable, extensible and reusable, and construction efficiency, safety and economical efficiency are remarkably improved.
