Summary:PROBLEM TO BE SOLVED: To provide a press-fitting device that can be installed even in a narrower lower space than a conventional press-fitting device.SOLUTION: A press-fitting device comprises: a reaction receiving member consisting of multiple reaction receiving blocks which are combined to obtain a little larger similar cross-sectional shape than a cross-sectional shape of a pole-shaped structure, and including multiple reaction receiving ribs with predetermined thickness formed at predetermined intervals in a circumferential direction of an outer periphery; multiple press-fitting jacks each including a piston and a cylinder accommodating the piston therein, and energizing a pressing force for press-fitting a steel sheet block under the ground; multiple upper brackets with each of which an engage groove to be engaged with the reaction receiving rib is formed, and which are engaged with the reaction receiving ribs by engaging at least a part of the reaction receiving ribs including a lower end face with the engage grooves and lock the cylinders in a state where the press-fitting jacks at one end side are projected at least partially; and a push ring which is connected with the other end side of the press-fitting jacks and abutted with an upper end face of the steel sheet block and energizes the pressing force of the press-fitting jacks to the steel sheet block.SELECTED DRAWING: Figure 1 【課題】従来の圧入装置に比べて狭い下部空間においても設置可能である圧入装置を提供すること。【解決手段】組み合わせることにより柱状構造物の断面形状より若干大きい相似形の断面形状となる複数の反力受けブロックで構成され、外周の周方向に所定間隔で形成された複数の所定厚の反力受けリブが設けられた反力受け部材と、ピストン及びピストンを収容するシリンダを有し、鋼板ブロックを地中へ圧入する押圧力を付勢する複数の圧入ジャッキと、反力受けリブと係合する係合溝が形成され、下端面を含む反力受けリブの少なくとも一部を係合溝に係合させることで各々の反力受けリブと係合するとともに、圧入ジャッキの一端側の少なくとも一部を突出させた状態でシリンダを係止する複数の上部ブラケットと、圧入ジャッキの他端側と連結され、鋼板ブロックの上端面と当接して圧入ジャッキによる押圧力を鋼板ブロックに付勢する押し輪とを備える。【選択図】図１
