[VI-617] Planning of Composite structure in starting shaft of large cross section shield tunnel (Part 2)
Keywords:Underground Structure, Starting shaft of Sheild Machine, Composite structure, High flow concrete, Fireproofing
In Chiba section of Tokyo Gaikan Expressway; the launch shaft on the H lamp shield had been demanded to complete immediately.
Therefore, we had been changed the method of structural form of the frame from the Cast-in-Place Concrete Structure (RC) to Composite Structure to shorten the process.
In the worksite, the piece of steel shell was erected by a large crane; and then after completion of the erection; high flow concrete was cast inside.
The construction plan and the technical scheme implemented in the field is reportedly written in this paper.
