摘要： PURPOSE:To maintain safety during work by drilling an intermediate vertical hole between vertical holes, inserting a steel pile with a joint and an intermediate steel pile with a joint into these holes, respectively, connecting both piles through joints and filling grout material between the piles and the wall of the vertical holes. CONSTITUTION:A number of vertical holes 2 are drilled at regular intervals on a circular line. A steel pile 3 with a joint is inserted into the vertical hole 2 and curing grout material 4 is filled between the wall of the vertical hole 2 and the steel pile 3 to build a cylindrical body 20. Next, an intermediate vertical hole 5, drilled partly into the vertical holes 2 adjacent to each other, is drilled. An intermediate steel pile 6 with a joint is inserted into the intermediate vertical hole 5 and T-shaped steel joints 16 on both sides of the steel pile 6 are inserted into the slit-pipe joints 10 on the steel pile 3. Then curing grout material 11 is filled between the wall of the intermediate vertical hole 5 and the intermediate steel pile 6 to build an intermediate cylindrical body 22.

摘要： PURPOSE:To reduce the manufacturing cost by use of a thin plate of a tank, by providing compressed air inlet and outlet and also replacing water inlet and outlet to connect to the groundlevel respectively and making the difference between the external pressure of the underground water pressure and the inner pressure of the stored compressed air to be a specified pressure. CONSTITUTION:An underground tank 1 for storage of compressed air is buried in a vertical shaft 4 of the excavated underground 3 bearing water 2. In this case, the underground tank 1 is closely sealed and the outlet and inlet 7 of compressed air 15 is connected to a compressor 9 on the ground through a pipe 8. A feed and discharge opening 13 of replacing water 12 is provided at the bottom thereof and connected to a replacing water tank 14 through a pipe 16. The compressor 9 is operated by making use of the excess electricity in the night time and the compressed air 15 is stored in the underground tank 1. In this time, the upper level of the underground tank 1 is made to be a specified depth D1 and the bottom level is made to be the depth D2 where the underground water pressure is almost equal to the maximum pressure of the stored compressed air. And the depth D1 at the upper level is made to be nearly 2/5-4/5 of the depth D2 of the bottom.

摘要： PURPOSE:To make it possible to facilitate removable of surplus produced during construction by preventing the collapse of a drilling hole, securing the safety of workers with ease and protecting underground water from contamination pollution. CONSTITUTION:A spray nozzle-built-in triple pipe rod 5 is inserted into a guide hole 4 drilled in a weak ground. The surrounding ground is forcibly broken down by injecting high speed steam jet into the subsoil while a grout material 14 is injected thereinto simultaneously. The triple pipe rod 5 is pulled up while it is rotated. The foundation improvement which builds up a column-shaped solid body 1 by curing the grout material is executed, corresponding to the scale of an underground vessel to be built, Drilling holes 15 for construction are installed on a simple substance of a column-shaped solid body or a set of or chains of column-shaped solid bodies, thereby building an underground vessel 3 in the drilled holes 15.
