Structural installation method for forming underground tunnels for easy intrusion of steel pipes and installation of waterproof steel plates in straight and curved sections

摘要

The present invention relates to a method for installing a structure for forming an underground tunnel in which it is easy to press-fit steel pipe for straight and curved sections and install waterproof iron plates. Of course, to make it easier In addition to this, in the sidewall forming method, a method using a pair of lead plates, which is completely different from the conventional sidewall forming method, is adopted, so that it is easy to propel a pair of lead plates in a shape corresponding to a steel pipe section press-fitted in a straight line and in particular a curve. Earth is prevented by a pair of lead plates so that the excavation of the soil inside the lead plate can be conveniently and quickly using excavation equipment rather than manual work. By making the waterproofing iron plate for formation very convenient and quick to install, and at the same time making it completely waterproof, As a result, it is possible to quickly and safely build a tunnel structure that is very simple, quick and stable to install while reducing material and transportation costs compared to the existing underground tunnel formation method, and is structurally very strong, robust and waterproof even after construction. .
