AI Technical Summary

Technical Problem

Existing technologies for concrete pouring methods used in bridge structures for steel-concrete composite gable columns are difficult to apply to substation frames, and suffer from problems such as complex construction, high cost, and insufficient stability.

Method used

A jacking device suitable for steel-concrete composite gable column structures was designed. It uses a concrete pump truck and a delivery pipe with a one-way valve, combined with an overflow/vent hole pipe. The construction is simplified by bolting, the welding process is reduced, and the one-way valve controls the concrete pumping process.

Benefits of technology

It improves the construction stability and economy of the substation A-frame structure, simplifies the construction process, reduces material waste and labor costs, and shortens the construction period.
