Description

TECHNICAL FIELD [0001] The present invention relates to a soundproof tunnel and a construction method thereof,

The present invention relates to a soundproof tunnel and a method of constructing the same. More particularly, the present invention relates to a soundproof tunnel and a method of constructing the same. More particularly, the present invention relates to a soundproof tunnel, The present invention relates to a soundproof tunnel and a method of constructing the same, which can reduce a construction cost and a maintenance cost and can safely perform a worker's maintenance for maintenance and repair work of a mining panel, thereby preventing a fall accident.

Generally, a tunnel-type soundproofing facility is installed on a road or a highway passing through a large-scale apartment complex or a large-scale residential complex complex, and this is generally called a soundproof tunnel.

Such a soundproof tunnel is an arched structure, and has a complete tunnel-like soundproof tunnel in which the whole is completely sealed and a half-tunnel type soundproof tunnel in which a part of the upper part is opened.

The soundproof tunnels are installed on the road by providing a plurality of straight struts and arched frames with the whole shape close to a semicircular or arcuate shape with a frame which traverses the road at regular intervals in the direction of the road and a sound absorber or reflector on the outside of the frame It is relatively perfectly blocked from propagating to the outside.

Korean Unexamined Patent Publication No. 10-2009-0042893 (published on April 5, 2009) discloses a soundproof tunnel having a soundproof wall so as to have good workability, aesthetic appeal, light weight construction, and reduction in construction cost and maintenance cost .

However, since such a conventional sound-proofing tunnel is formed on the straight strut and has the same cross-sectional structure as the continuous connection structure between the arched frame forming the upper ceiling and the end of the straight strut, the burden due to the vertical load acting on the central frame is large There was a problem to be overcome.

That is, the straight strut vertically raised on the foundation concrete provided on both sides of the road is constructed of a steel material having a wide cross-sectional area in consideration of rigidity while sufficiently supporting the arched frame structure as the ceiling structure.

In this case, in order to form the ceiling of the soundproof tunnel, the arc-shaped frame is continuously connected to the end of the straight strut to form the arc-shaped ceiling, so that the arched frame without considering the rigidity is also constructed with the steel material having the same section as the straight strut.

As a result, the vertical load acting on the central frame part formed by the arched support is increased, and the overall weight of the arched frame is increased as the width of the road is widened. As a result, There was a limit in reducing the construction cost.

In addition, when the span between the two straight stanchions increases as the width of the road becomes wider, the foundation concrete works on the floor of the central part of the road so as to securely support the arc-shaped ceiling, The total amount of steel material used during the construction of the soundproof tunnel is increased and the foundation work must be separately performed at the center floor of the road so that the overall construction cost is increased and the construction period is lengthened .

There was a risk of secondary accidents caused by the collision of the vehicle with the central support in the event of an accident in a soundproof tunnel, with the central landmark installed at the center of the road.
