A construction method of cylindrical coal shed net shell vertical gable starting with a transfer station crossing a hole

By dividing the vertical gable wall into six starting units, using double-layer guy ropes for layered anchoring, and employing auxiliary lifting equipment for temporary load-bearing closure, the construction difficulties caused by the top transfer station passing through the opening in a large-span bolted spherical reticulated shell structure were solved. This approach shortened the construction cycle, improved safety, and enhanced installation accuracy. It is suitable for columnar coal shed reticulated shells with transfer stations passing through openings and other large-span incomplete reticulated shell structures.

AI Technical Summary

Technical Problem

Existing technologies cannot effectively address the problems of structural discontinuity, long construction period, unstable hoisting, weak wind resistance, and low installation accuracy caused by the top transfer station crossing the opening, especially in the initial construction of the gable wall of a large-span bolted spherical shell structure.

Method used

The method employs a six-section vertical gable wall starting unit, with different attitudes for hoisting, double-layer guy ropes for layered anchoring, temporary support and closure of auxiliary hoisting equipment, and full-process precision control. This includes steps such as dividing the construction area with the structural expansion joint as the boundary, dividing the vertical gable wall starting unit into six sections and hoisting it with different attitudes, double-layer guy ropes for layered anchoring, temporary support and closure of auxiliary hoisting equipment, and deflection monitoring.

Benefits of technology

It significantly shortens the construction period, improves hoisting safety and structural stability, enhances wind resistance and installation accuracy, and is suitable for columnar coal shed reticulated shells with transfer stations passing through the openings on the top, as well as other large-span incomplete reticulated shell structures.
