Title: Shield tunnel construction method and filler
Inventor: ASO TOSHIMITSU
IPC: E21D11/00
Filed: 2001-11-07
Abstract: PROBLEM TO BE SOLVED: To rationally hold the ground of an overbreak part in a shield tunnel construction method. SOLUTION: When performing an overbreak of a cross section larger than a normal cross section at a turning part of a shield driving machine or part of a tunnel at which its cross section is altered, the overbreak part A is excavated while holding the ground by filling the overbreak part A with the gel filler 5 having fluidity and non-permeability to the ground. After the shield driving machine 1 has passed the overbreak part, a back-fill material 3 is filled, the filler is recovered, and the back-fill material is cured. This method is similarly applied to a part of the tunnel at which its cross section is enlarged or contracted. The filler is obtained by mixing bentonite, water, and polyacryl-amide- based high-molecular coagulant so as to display gel properties. Their compounding ratios are each set within the ranges of 77.1-85.0 wt.%, 14.7-21.9 wt.%, and 0.1-1.4 wt.%.
