Abstract: PROBLEM TO BE SOLVED: To totally generate no residual soil, to exhibit large water-permeability and to individually clean contaminated underground water in respective aquifers by one cleaning body without making underground water flowing in one aquifer flow to the other aquifer through the cleaning body.
SOLUTION: The underground cleaning body 10 has a hardly water-permeating layer 23 between the aquifer 22 and the aquifer 24 is made on a contaminated ground 30 existed with two or more of aquifers. The cleaning body divisions 11, 13, 15 positioned on the aquifer are formed by a mixture body including at least a cleaning material, a bioerodible polymer and original ground soil. Hardly water-permeating division layers 12, 14 for shutting off mutual communication of underground water flowing in aquifers at both vertical sides clamping a hardly water-permeating layer are arranged in the cleaning body division positioned in the hardly water-permeating layers 12, 14.

Abstract: PROBLEM TO BE SOLVED: To maintain air-tightness inside a casing pipe, and to prevent an intrusion of soil and water into a lock mechanism part.
SOLUTION: In this extendable casing 10 for sand pile placing, an inflatable ring 71 to be expanded by filling air to abut on an inner casing 20 is provided at the predetermined position of an outer casing 40, in which a lower part of the inner casing 20 is positioned in the shrinking condition. The inner casing 20 is provided with a seal rubber 83 energized downward by a spring 85 at a position over the seal position of the inflatable ring 71. The outer casing 40 is provided with a projecting part 72 projected inside the pipe so that the seal rubber 83 pushed from over thereof abuts on the projecting part 72.

Abstract: PROBLEM TO BE SOLVED: To provide a soil improving method which is applicable to a soft ground under the water surface, carried out on a stable scaffolding without an influence of meteorological conditions, tide level, wave force, or the like, and makes effective use of floating matter generated in bulk at the time of soil improvement.
SOLUTION: The soil improving method is comprised of the following steps. In the first step, a container structure (e.g. a caisson 1) is set on the ground (G) under the water surface, and vertical boring is carried out in an area below the container structure (1) on the ground (G) under the water surface, by using soil improving devices (4, 5), followed by inserting a hardener jetting means (7) from the soil improving devices (4, 5). In the following step, the hardener jetting means (7) functions to horizontally jet a hardener while being rotated, and then the hardener jetting means (7) is drawn upward to thereby carry out the soil improvement. According to the soil improving method, waste matter (e.g. slime S) which is a mixture of the hardener and the soil of the ground (G) under the water surface generated during execution of the hardener jetting step, is housed in the container structure (1).

Abstract: PROBLEM TO BE SOLVED: To provide a concrete placing form with a heat insulating material excellent in handling and workability and an outside heat insulation method making use thereof preventing a heat insulating material or a venting layer from being crushed when a concrete is placed, preventing a separator from passing through the heat insulating material and preventing the heat insulating material from falling down in the case of bar arrangement or in the case the concrete is placed.
SOLUTION: The concrete placing form 10 laminates an exterior finishing plate 11 used for an outside plate of a building, the heat insulating material 12 and a concrete thin plate 13 embedding a reinforced bar arrangement 14 in due order, and the reinforced bar arrangement 14 is partially exposed from the surface of the concrete thin plate 13.
