CONSTRUCTION METHOD FOR CLOSED PARALLEL TUNNEL AND CLOSED PARALLEL TUNNEL USING THE SAME
The present invention provides an environmentally friendly construction method for a closest parallel tunnel, which can minimize a topographic loss and can reduce construction periods, and a closest parallel tunnel using the same. According to the present invention, the construction method for a closest parallel tunnel includes: an excavation groove construction step of excavating a first ground to be excavated and forming an excavation groove between a first tunnel and a second tunnel, wherein the closest parallel tunnel comprising a first tunnel and a second tunnel close to each other is constructed on the first ground to be excavated; a single wall construction step of continuously embedding multiple column support members in the excavation groove and placing and curing a curable fixing agent in the excavation groove to form a single wall with the column support member; a tunnel excavation step of excavating a second ground to be excavated in the longitudinal direction to form the first tunnel and the second tunnel; and a passage construction step of forming a frame in order for the passage of the first tunnel and the second tunnel to be constructed as a ceiling support member is connected to the column support member. The excavation step and the passage construction step are repeatedly constructed in the longitudinal direction of the first tunnel and the second tunnel in order.
