The present invention relates to a prefabricated arch tunnel using a tunnel member having a reinforcing rib and a construction method thereof, and in particular, a concrete structure of a specific type for building an arch tunnel is manufactured in advance in a factory using several unit members, and transported to a site by a unit. By assembling the member, and then finishing the joint portion, the present invention relates to a prefabricated arch tunnel using a tunnel member having a reinforcing rib capable of rapid tunnel construction, economical and beautiful scenery, and a construction method thereof.

In general, arch structure is a structural form that has been used in civil engineering structures and buildings for a long time.

Since the arch structure is easy to dissipate stress against external earth pressure or through load, it is economical because the member section can be made thinner than other cross-sectional shapes under the same stress condition, and in particular, the arch structure is in harmony with the surrounding landscape. Although possible, the construction site was constructed in a box structure using conventional cast-in-place concrete.

According to this conventional construction method, since the construction site installs copper bars and formwork, reinforces steel bars, reinforces and cures concrete, and dismantles formwork, a large number of people are added to the construction site. As it is divided into three stages of construction, slab, etc., it takes a long time to construct, and it is difficult to prevent the settling crack of the slab.In particular, under the condition that the same stress is applied to the structure, the thickness of the concrete increases, so the weight of the structure increases and the ground subsidence is increased. In addition to poor stability, concrete quality control is required.

In addition, when constructing the box structure, careful installation is required for the support, many skilled workers are required, and the tunnel shaft has a problem that damages the tunnel landscape because a triangular wing wall is separately formed.

Particularly, large-sided concrete is costly due to cracks and settlement cracks due to hydration heat during concrete casting, and life-saving accidents occur frequently due to the collapse of the structure due to carelessness of workers during the installation of jibo. There is a lot of problems, such as not being able to fill the area around the structure until the construction period is prolonged, causing inconveniences in the traffic, such as restricting the passage of vehicles, to be the subject of a complaint.
