2. Description of the Related Art In the past, when a large earthquake occurred, a highway collapsed with its pedestals, a building collapsed, and electricity, water, gas, and communication lines in daily life were disconnected, resulting in a great disaster. . In the conventional technology, since all of them are embedded and fixed underground, they are integrated with the ground shell and move together, so that like the Hyogo ken Nanbu Earthquake, the amplitude is 18 cm, vertical movement is 10 cm, and ground movement is 2 km / h. Destroy any sturdy design.

FIG. 1 shows a conventional example for comparison with the present invention,
Below the pedestal 3 of the highway 2 on which the vehicle 1 travels, there is a stake 5 struck on the surface 4 of the ground, which fixes the pedestal.
In the event of a big earthquake, the pedestal is 3'because of horizontal vibration 6 and vertical vibration 7.
The highway collapses like a 2'because it bends or bends.

Railroad rails are also fixed to the surface of the earth via sleepers, and water, gas, electricity, communication lines, etc. are buried underground,
Destroy as well in an earthquake.

[0005]

Since conventional structures such as roads, buildings, roads, railroads, gas, and water have underground foundations embedded therein, the structures are integrated with the surface of the earth during an earthquake and roll, Pitching, and thus the structure cannot withstand vibrations and its resonances, and breaks, falls, deforms, bends, or cuts. The present invention is to prevent these.

[0006]

Structures such as highway legs, roads, railroads, buildings, water, electric wires, gas and telephone lines are made independent of the movement of the ground. Specifically, between the structure and the ground surface, a part where the structure can move vertically and horizontally and a stopper that fixes this in normal times are provided. Alternatively, by making it relatively movable in the vertical direction, the structure can be protected from destruction even in the event of a large earthquake vibration without following it.
