Description of the Related Art Along with traffic on railways and roads, vibrations propagate to surrounding houses and the like via the ground, and various kinds of damage caused by the vibrations have become a problem. As a countermeasure, a method using ballast mats or slab mats in the floor of a railway or the like has been adopted, but it is difficult to say that it is a sufficient countermeasure. Therefore, FIG.
As shown in (1), there has been proposed a method in which a vacant groove 4 is dug between a vibration source such as a railway and a place where a vibration occurs such as a house to cut off an edge thereof to interrupt the propagation of the vibration. A method of arranging a vibration absorbing material 41 having a laminated structure of a rubber plate or the like between the side walls of the vacant groove 4 and absorbing vibration by deformation of the vibration absorbing material 41 has also been considered.

ではない。In the case of the above-mentioned conventional method, when rainwater or groundwater or the like enters the vacant groove 4, the vibration is easily propagated because the water is an incompressible body. Therefore, it is necessary to always maintain a hollow state so that water does not infiltrate into the vacant groove 4, but it is not easy to manage water stoppage underground.

The vibration-absorbing sheet 11 is made of a rubber-based material, a plastic-based material, or a high-damping material such as chloroprene rubber whose hardness is adjusted. The air bag 12
A large number of press-fitted air bladders 12 joined into a sheet shape are used. Then, the vibration-absorbing sheet 11 and the sheet-shaped air bag 12 are superposed on each other in a plurality of layers to form the plate-shaped vibration-absorbing material 1. Further, as shown in FIG. 4, an integrated structure in which a number of air bubbles 13 are sealed in the vibration absorbing sheet 11 can be adopted. When the vibration-absorbing material 1 is set up in the groove, as shown in FIG. 2, a frame member 14 such as a steel material for setting up is attached to a peripheral portion of the vibration-absorbing material 1.

The bottom and both sides are held by concrete walls. Next, the vibration absorbing material 1 is set up in the groove 2. At this time, since the frame member 14 is attached to the peripheral portion of the vibration-absorbing material 1, the plate shape of the vibration-absorbing material 1 can be maintained at the time of setting up, and the setting can be easily performed. After setting up the vibration-absorbing material 1,
The backfill material 3 is filled around the vibration absorbing material 1 in the groove 2 without any gap. As the backfill material 3, soil or soil mixed with cement, concrete, or the like is used. Thus, the construction of the vibration reduction structure is completed.
