PROBLEM TO BE SOLVED: To solve the problems of being large in improvement cost in a solidification method and of requiring large cost for industrial waste cost, though respective methods are selected, by taking into consideration whether or not to improve a sandy system or a viscous system from the water content, a layer thickness and an earth property, or which selection-combination of the method must be selected by a peat layer or respective layer thicknesses, by existing in a mutual layer stratification state of sandy soil, sandy silt, silt and viscous soil and a state of depositing the peat layer much on a Japanese coast.SOLUTION: This method is formed as means capable of uniformly mixing a solidification agent by fluidizing by adding vibration and water in viscous strength of a viscous soil layer of viscous soil and a peat layer or is formed as means capable of solidifying the peat layer of a large clearance while executing forced compression, by vibrating-compacting a sandy soil layer within a constant cost range, by improving a wide range simultaneously with compaction, the forced compression and solidification, by taking into consideration various elements being the problem in a mutual layer and the peat layer of the sandy soil and viscous soil, and is further formed as means capable of also reducing industrial waste disposal cost by this method.SELECTED DRAWING: Figure 1
【課題】砂質土、砂質シルト、シルト、粘性土の互層成層状態、ピート層が日本の沿岸には多く堆積した状態にあり、含水量、層厚、土性から砂質系か、粘性系の改良するか、ピート層か又は各層厚により、工法の選定、組み合わせを選定すべきかを考え、各工法を選定するが、固化工法は改良費が大きく、又産廃費用に大きい費用が掛かり課題であった、【解決手段】本工法は上記、砂質土、粘性土の互層、ピート層で課題である諸要素を考え、締固、強制圧縮、固化を同時に広範囲改良し、一定の費用の範囲内で砂質系土層は振動締固め、粘性土、ピート層の粘性系土層の粘性強度は振動と水を加え流動化させることにより固化剤が均一に混合出来る手段にした、又間隙の大きいピート層は強制圧縮を行いつつ、固化の出来る手段とした、尚本工法により産業廃棄物処理費用も軽減出来る手段とした。【選択図】図１
