TWO ARCH TUNNEL GIRDER CONSTRUCTION METHOD FOR CONSIDERING SECURING CONSTRUCTION SPACE AND REINFORCING ROD REINFORCEMENT

摘要

PURPOSE: A two-arch tunnel girder construction method for considering securing construction space and reinforcing rod reinforcement is provided to simplify the processing and assembly of steel reinforcement and to ensure excellent application property and profitability.;CONSTITUTION: A two-arch tunnel girder construction method for considering securing construction space and reinforcing rod reinforcement constructs an inner post and a upper girder at the upper side of the inner post in a longitudinal direction while constructing a central tunnel. The lining end part is supported at both sides of the top girder. The top girder is formed with a trapezoid shaped lower sphere and a square section shaped upper sphere.;COPYRIGHT KIPO 2010
