    • PROBLEM TO BE SOLVED: To provide a demolition method for a hollow tower-like structure which can prevent harmful substances from being scattered by a filling failure even if an inorganic curable fluid or the like is not sufficiently filled although a scattering covering layer with a moderate thickness for covering the harmful substances with the inorganic curable fluid such as mortar is formed.
      SOLUTION: A tubular form 3 is installed in the hollow tower-like structure (chimney) 1 wherein the harmful substances exist on an inner peripheral surface; the inorganic curable fluid 9 is filled into a space between the tubular form 3 and the hollow tower-like structure 1; and after the curing of the inorganic curable fluid 9, the hollow tower-like structure 1 including the tubular form 3 is cut in round slices in a circumferential direction. A plurality of injection holes 10 are formed in estimated cutting positions, respectively; a fire-resistant lining material 2 is impregnated with an immersion solidification agent 11 which is injected from the injection holes, and after the solidification of the immersion solidification agent, they are cut in round slices.

    • PROBLEM TO BE SOLVED: To provide a well structure for fracturing capable of generating a splitting, which occurs during high-pressure injection of a chemical into the ground, in a target direction.SOLUTION: A well structure comprises: a casing 6 that is vertically installed in a pit 4 in the ground and has a water passing part 6a at its lower part; a filter layer 30 that is formed between the casing and an inner peripheral surface of the pit; a flexible drill guide pipe 20 extending from a vertical pipe part 20a extending along an inner surface or an external surface of the casing pipe wall from the land surface to the vicinity of the water passing part, through a curved pipe part 20b, to a lateral pipe part 20c with its tip opening protruding laterally outward; and fracturing fluid injection means 10 with an opening of an inlet for the fracturing fluid in the vicinity of the water passing part. At least a tip part of the lateral pipe part is formed at a guide edge in a straight cylinder shape. An opening part of the guide edge is set at the depth comparable to that of the water passing part.
    • 要解决的问题:提供一种能够产生在目标方向上将化学物质高压注入地面期间发生的分裂的压裂井结构。解决方案:井结构包括:垂直的壳体6 安装在地下坑4中,并在其下部具有通水部分6a; 形成在所述壳体与所述凹坑的内周面之间的过滤层30; 弹性钻杆引导管20,其从沿管壳壁的内表面或外表面延伸的垂直管部分20a通过弯曲管部分20b从地面到水通过部分附近延伸到侧面 管部20c,其顶端开口横向向外突出; 以及压裂液注入装置10,其具有用于在通水部附近的压裂流体的入口的开口。 侧管部的至少顶端部形成为直筒状的引导边缘。 引导边缘的开口部分设置在与水通过部分相当的深度。
