摘要： PURPOSE:To raise the mixing effect of soil by a method in which slits are formed in many mixing blades projected from the peripheries of plural rotary shafts in such a way as to permit crushing and mixing to perform in parallel during the passage of soil and sand. CONSTITUTION:A driver is attached to the upper part of plural rotary shafts 2 having excavating bits 1 on their lower parts, and connecting bands 4 are provided to the lower parts of the shafts 2. Many mixing blades 3 are projectionally provided to the periphery of the shaft 2 and slits 5 are provided for the blades 3 to minimize the contact area with soil. The blade 3 consists of a rectangular stiff frame 31 and traversal materials 32 between which slit 5 is formed. The shafts 2 are turned to excavate the ground, the soil blocks are contacted with the blades 3 within the rotating locus of the blades 3 and passed through the slits 5 to finely divide the soil lump by the stiff frame 31 and the traversal materials 32. The deterioration of the quality of structure after mixing and stirring can be prevented.

摘要： PURPOSE:To facilitate the excavation on the concave section side of the steel pile having a cross-section of H-shape or the like preventing the solidification of the concrete within the concave section by covering the section with a water shielding sheet. CONSTITUTION:A steel pile 4 has two pertition pieces 2 fastened between two horizontal side pieces 1 to form a hollow section 11 surrounded by the side pieces 1 and the pertition pieces 2 while two concave sections 3 are formed opening there-outside in the opposite direction. The concave section 3 is covered with a compound sheet 6 composed of a net sheet 8 and a water shielding sheet 9. The net sheet 8 is provided to maintain own shape of the section against external force to a certain extent while the water shielding sheet 9 is required to stop the mortar component of the concrete. The existence of the compound sheet 6 facilitates the excavation of the concave section to connect the underground wall to the section 3 without solidification of the concrete therewithin.
