摘要： PROBLEM TO BE SOLVED: To prevent a mounted structure from being settled unevenly, by remaining a perpendicular degree of a pile even when liquefaction occurs.SOLUTION: According to an underground reinforcement construction method, a number of piles are installed in the ground around an existent structure. The method includes a penetration step, a tilting step and a connecting step. In the penetration step, pile members 10 and steel members 12 are installed in the ground as an integrated body by using the perpendicular pile members 10 which are installed at predetermined intervals around the existent structure as piles and one or more orthogonal steel members 12 which are connected to lower portions of the pile members 10 in such a manner that the lower end side thereof is rotatable via a support shaft, and disposed along side portions of the pile members. In the tilting step, the steel member 12 installed together with the pile member 10 in the penetration step is rotated while directing the upper portion side of that steel member toward an upper portion of an adjacent pile member which is installed separately, with a support shaft 14 as a fulcrum. In the connecting step, the upper side of the steel member 12 tilted at a predetermined angle in the tilting step is connected to the upper portion of the adjacent pile member 10.
摘要翻译：要解决的问题：为了防止安装结构不均匀，即使在发生液化时也保持垂直桩的垂直度。解决方案：根据地下加固施工方法，在现有的地面周围安装了多个桩结构体。该方法包括穿透步骤，倾斜步骤和连接步骤。在穿透步骤中，桩构件10和钢构件12通过使用以预定间隔围绕现有结构安装的垂直桩构件10作为一体体安装在地面中，并且一个或多个正交钢构件12 连接到桩构件10的下部，使得其下端侧能够经由支撑轴旋转，并且沿桩构件的侧部配置。在倾斜步骤中，与穿孔步骤中的绒头构件10一起安装的钢构件12旋转，同时将钢构件的上部侧朝着与单独安装的相邻桩构件的上部一起引导，支撑轴 14为支点。在连接步骤中，在倾斜步骤中以预定角度倾斜的钢构件12的上侧连接到相邻的桩构件10的上部。

摘要： PROBLEM TO BE SOLVED: To provide a material for a sand compaction pile construction method having a consolidation characteristic of using steel slag, and a preparation method of a sand compaction pile using its material.
SOLUTION: This material for the sand compaction pile construction method is formed by setting the mass mixing ratio of the steel slag and blast furnace annealing slag to 7:3 to 0.5:9.5. The material for the sand compaction pile construction method is formed by setting the mass mixing ratio of the steel slag, the blast furnace annealing slag and blast furnace water granulation slag to 8.5:1.5 to 0.5:9.5. In respective cases, the material for the sand compaction pile construction method is formed by mixing the blast furnace annealing slag of setting the fine grain content mixing ratio F
c % by compaction particle crushing. A pile is prepared by a casing pipe 1 by simultaneously using rotational press-in and driving-back, by using any material for the sand compaction pile construction method.

摘要： PROBLEM TO BE SOLVED: To reduce displacement of the ground during construction while executing soil improvement in the ground near a quay wall or a revetment on a beach, at a river mouth or in a lake subject to a water level change due to the tide and thereby preventing a target structure such as the quay wall or the revetment from being adversely affected.SOLUTION: When executing soil improvement of the ground near a quay wall or a revetment on a beach, at a river mouth or in a lake subject to a water level change due to a tide, a soil improvement method with reduced displacement executes construction: at a site away from the sea so as to prevent a target structure 1 such as the quay wall or the revetment from being adversely affected by an excess pore water pressure which occurs during the construction at low tide; and at the site close to the sea at high tide. Thus, the soil improvement method with the reduced displacement reduces displacement of the ground during the construction by changing the construction site in accordance with a water level change due to the tide and thereby preventing the target structure 1 such as the quay wall or the revetment from being adversely affected.
