AI Technical Summary

Technical Problem

The existing steel pipe pile ice-breaking cone structure increases the waterline area during ice-free periods, leading to increased wave loads and affecting safety. Furthermore, the installation and dismantling operations are cumbersome, increasing the workload of workers.

Method used

An ice-breaking device was designed, comprising a sleeve, an ice-breaking structure, and an arc-shaped guide bar. The ice-breaking structure consists of multiple sets of vertically connected ice-breaking cones. It can be quickly adjusted and positioned through a positioning component and a rope system, reducing the volume of the cones and simplifying the installation process.

Benefits of technology

Without compromising ice-breaking efficiency, the cone volume was reduced, wave load was decreased, installation and disassembly processes were simplified, and work efficiency and safety were improved.
