PROBLEM TO BE SOLVED: To provide a termite prevention execution method and a tool used therefor allowing treatment with a termite prevention agent even in a narrow underfloor space in a foundation heat-insulating structure of a building. SOLUTION: A tunnel-like space 12 surrounded by heat insulating materials 14, 16 is formed along a corner part (a portion of a corner 11) where an inside surface 13a of a continuous footing 13 (an erected part) and an upper face 15a of moisture-proof concrete 15 (a horizontally installed section) join with each other. A long-sized termite-preventing treatment tool 30 is inserted from an opening 12a at the side of the tunnel-like space 12 (an arrow mark D) and inserted into the inner part of the tunnel-like space 12 to sprinkle the liquid termite-preventing agent into the space 12.

PROBLEM TO BE SOLVED: To provide a termite prevention system capable of properly supplying a termite prevention agent over the whole length of a joint part of concrete structural bodies. SOLUTION: This termite prevention system is provided with a plurality of pipe members 12 for supplying the termite prevention agent into the joint part 106 of the concrete structural bodies 102, 104 to prevent termite from intruding into an indoor part through the joint part. The pipe member includes a first pipe member 14 and a second pipe member 16. The first pipe member is positioned on the upstream side of the pipe member, and a filling port for pouring the termite prevention agent into the pipe member is formed at its upstream side end. A second pipe part is extended from a downstream side end of a first pipe part and is positioned on the downstream side of the pipe member. An opening part 30 for letting the termite prevention agent pass through it to make it flow to the outside of the pipe member is formed on its pipe wall. A second pipe part is arranged along the joint part and near the joint part, and a plurality of the second pipe parts having the predetermined length are continuously arranged over the whole length of the joint part to supply the termite prevention agent over the whole length of the joint part.

PROBLEM TO BE SOLVED: To provide a chemical liquid impregnation system capable of impregnating wood with a predetermined amount of a chemical liquid and capable of reducing the irregularity of the quality of the treated wood. SOLUTION: The chemical liquid impregnation system 1 comprises a hermetically closable tank 10, a chemical liquid storage tank 20, the pressure pump P2 for introducing the chemical liquid into the tank 10 from the chemical liquid storage tank 20 through an introducing passage 30, a pressure adjusting valve 45 for adjusting the pressure in the tank 10, a liquid level sensor 52 for detecting the filling time when the tank 10, in which wood is housed, is filled with the chemical liquid, an introduced chemical liquid amount detector for detecting the amount of the chemical liquid introduced into the tank 10 from the chemical liquid storage tank 20, and an impregnated chemical liquid amount control means which detects the impregnation amount of the chemical liquid on the basis of the introducing amount of the chemical liquid on and after the filling time on the basis of the detection due to the liquid level sensor 52 and the detection due to the introduced chemical liquid amount detector and controls the drive of the pressure pump P2 at the point of time when the impregnation amount of the chemical liquid reaches a predetermined value to stop the introduction of the chemical liquid.

PROBLEM TO BE SOLVED: To prevent the collapse of a stone by effectively utilizing lumber such as thinned wood. SOLUTION: The horizontal lumbers 11 and 13 extended in the horizontal direction are arranged on the surface 2 of a slope of a levee 1 or the like at specified intervals, and the vertical lumbers 12 extended in the vertical direction are arranged at the specified intervals. A wooden frame body 10 in which the horizontal lumbers 11 and 13 and the vertical lumbers 12 are superposed in a latticed shape and connected to one another is installed, and sheet-shaped bodies 16 grounded to the face 2 of the slope are mounted while straddling the horizontal lumbers 11 of the wooden frame body 10. The stones 18 for slope protection and for a sheet-shaped material weight are juxtaposed in lattice openings 17 formed among the horizontal lumbers 11 and 13 and the vertical lumbers 12.
