Abstract

PROBLEM TO BE SOLVED: To realize a foundation resistant to earthquake.SOLUTION: A mechanism for reducing a vibration by using a pile comprises driving piles into the soft ground and reducing the vibration by the bending of the piles.

Description

  The present invention relates to a foundation pile.

  At present, the seismic reduction mechanism is not suitable for soft ground, and is needed.

  However, although it is piled on the soft ground, there was a drawback of vibration along with the foundation, pile and ground.

  The problem to be solved is to separate the ground and foundation movement.

  In order to achieve the above object, the present invention provides a vibration-reducing pile characterized in that the movement of the foundation is reduced from the ground using the deflection of the pile as claimed in claim 1, The hole diameter is dug larger than the diameter, the lower part of the pile is fixed with concrete, etc., the middle part and the upper part space are filled with weak binding material such as lime, and the foundation and the pile are combined on it. Have

  In order to achieve the above object, according to the present invention, as an improvement measure of the present invention, in order to increase the deflection of the pile, the pile supporting the foundation on which the bottom surface of the foundation can slide is divided and provided in the deep underground. The head of the approximate pile and the upper pile are fitted, a large hole wall is provided around the approximate upper pile, and a space or a vibration reducing material is provided in the space. Anti-seismic pile driving mechanism with the foundation fixed and held by the upper pile head

  In order to achieve the above object, according to the present invention, as an improvement measure in claim 3, in order to increase the deflection of the pile, an uneven groove is provided in the peripheral wall of the pile supporting the foundation in the thread or ring. An anti-seismic pile mechanism.

When the ground moves due to an earthquake, the lower part of the pile co-seismics with the ground, and the upper part bends due to the inertial force of the foundation and structure, breaking the weak binding material and resisting the movement of the pile to suppress the vibration. In other words, it reduces the vibration.

The pile driving mechanism according to the present invention has an advantage that the upper part breaks the weak binding material, resists the movement of the pile, and suppresses the vibration. The space is filled with rubber and weak particles such as lime, and rubber and small particle material with gravel and sand, and the foundation and pile are joined together.
Rubber absorbs fine vibration and gravel, and sand has an effect of reducing vibration by slip resistance.

 In particular, the functional material filled in the upper portion may be molded as a single body or a composite, and rubber or the like is particularly possible.
