Description
【発明の詳細な説明】 イ．発明の目的 （産業上の利用分野） 建築工事における基礎工事，特にベタ基礎工事に対して
適用される。Detailed Description of the Invention a. Purpose of the invention (industrial application field) It is applied to foundation work in construction work, especially solid foundation work.
（従来の技術） ベタ基礎中空部を排土等で全体に埋め戻すことが行なわ
れていた。(Prior Art) The solid hollow portion of the foundation has been backfilled with soil or the like.
（発明が解決しようとする課題） 従来の工法では，ベタ基礎中空部を排土等で全体に埋め
戻すため，基礎全体が重くなり，地震に対しての剪断力
が大きくなるため，本願発明は，基礎全体を軽量化する
ことで地震に対しての剪断力を小さくすることを目的と
している。(Problems to be Solved by the Invention) In the conventional construction method, since the hollow portion of the solid foundation is backfilled with soil or the like, the entire foundation becomes heavy and the shearing force against an earthquake becomes large. , The purpose is to reduce the shear force against earthquakes by reducing the weight of the entire foundation.
ロ．発明の構成 （課題を解決するための手段） 本願発明は，上記課題を解決するために，ベタ基礎中空

め戻しを行うことを特徴とする軽量中空埋め戻し工法を
提供するものである。B. Configuration of the Invention (Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention is characterized in that the hollow portion of a solid foundation is made lighter, and backfilling is performed by a lightweight backfilling material. It provides a lightweight hollow backfilling method.
（作用） 従来埋め戻しに使用している土は，単位体積重量が1.8
〜2.0t/m3であり，これよりも軽量な塩ビパイプを使用
することにより，空胴が増え基礎全体が軽量化できる。(Function) The soil used for backfilling has a unit volume weight of 1.8
It is up to 2.0t / m 3 , and by using a lighter weight PVC pipe, the number of cavities increases and the weight of the entire foundation can be reduced.
そして，該パイプを連続して並べた後，空げき率の大き

えられるようにする。Then, after arranging the pipes in succession, backfilling the crushed concrete and pumice with a high void ratio makes the entire foundation lighter and more integrated so that it can withstand the compressive force.
ハ．発明の効果 基礎部が軽量化し，地震に対しての剪断力が軽減するた
め，地耐力のない軽弱地盤の液状化にも対応できる。C. Effects of the invention Since the foundation is lightened and the shearing force against earthquakes is reduced, it is possible to cope with the liquefaction of light and weak ground without bearing capacity.
