GROUND IMPROVEMENT METHOD AND IMPROVEMENT BODY
To provide a ground improvement method excellent in global environmental property and an improvement body formed by the method, contributing to realization of carbon neutral, by effectively using carbon dioxide (CO2) contained in exhaust gas, specifically, by fixing the exhaust gas generated from a compressor etc. of a plant facility or an improvement machine and by effectively using CO2 contained in the exhaust gas for formation of the soil improvement body.SOLUTION: A ground improvement method forms an improvement body K by using a solidification material 1 absorbing carbon dioxide (CO2) and solidifying by contact with CO2. An exhaust gas exhausting part 13 of a heavy machine 3, a plant machine, etc. is connected to a compressor, to form a constitution of feeding compressed exhaust gas 2 from the compressor to a rod 5 of an improvement machine. The solidification material 1 is injected from an injection hole 15 of the rod 5 together with the exhaust gas 2, CO2 contained in the exhaust gas 2 is absorbed in the solidification material 1 to accelerate a carbonation reaction to solidify, and the improvement body K is formed.SELECTED DRAWING: Figure 1
【課題】排気ガスに含まれる二酸化酸素（ＣＯ２）を有効利用すること、具体的には、コンプレッサー等のプラント施設や改良機から発生する排気ガスを固定し、かつ、排気ガスに含まれるＣＯ２を改良体の造成に有効利用することによりカーボンニュートラルの実現に寄与する、地球環境性に優れた地盤改良工法および同工法により造成される改良体を提供する。【解決手段】二酸化酸素（ＣＯ２）と接触するとＣＯ２を吸収して固化する固化材１を用いて改良体Ｋを造成する地盤改良工法であって、重機３、プラント機械等の排気ガス排出部１３とコンプレッサーとを連結して前記コンプレッサーから圧縮された排気ガス２を、改良機のロッド５へ送り出す構成とし、前記ロッド５の噴射孔１５から前記排気ガス２と共に前記固化材１を噴射し、前記固化材１が前記排気ガス２に含まれるＣＯ２を吸収して炭酸化反応を促進させて固化することで改良体Ｋを造成する。【選択図】図１
