Claims (1)
- 既設のトンネル等の中空地下構造物の上方で前記中空地下構造物と直交する方向の近接位置に地下構造物を構築する地下構造物の構築方法において、既設の中空地下構造物の側部両側に発進立坑と到達立坑とを築造し、既設の中空地下構造物上方には、少なくともこの中空地下構造物が浮力により浮上することを防止できるだけの高さの土砂を残して土砂を掘削し、新設する地下構造物を、発進立坑から到達立坑に向けて水平に移動しながら、当該箇所の残された土砂を徐々に取除き、既設の中空地下構造物には必要な荷重が絶えず作用するよう、この土砂と置換させながら新設の地下構造物を既設の中空地下構造物の上方に設置することで、前記既設の中空地下構造物上方に残された土砂による既設の中空地下構造物への浮力による浮上防止に必要な荷重を新設する地下構造物に徐々に置き換えて行くことを特徴とする地下構造物の構築方法。
