摘要： PROBLEM TO BE SOLVED: To prevent the reduction in stirring efficiency even when reducing a torque in a ground improving body creating device.
SOLUTION: A passage for high-pressure fluid is formed in an injection rod 11, and a high-pressure fluid is injected from injection nozzles 20 and 22 in ground improvement. Stirring blades 12 extending radially outward to the axis of the injection rod are provided on the circumference of the injection rod, and the stirring blades are rotated according to the rotation of the injection rod. The injection nozzles are arranged on the tip parts of the stirring nozzles and comprise nozzle ports opened toward the injection rod. In the area separated from the injection rod, considering that the ground is stirred by high-pressure jet, and the torque is proportional to the distance from the central part when the stirring blades are rotated, the torque acting on the vicinity of the tip parts of the stirring blades can be minimized.

摘要翻译：要解决的问题：即使当减少地面改善体产生装置中的扭矩时，也可以防止搅拌效率的降低。解决方案：在注射杆11中形成用于高压流体的通道，并且从注射喷嘴20和22注入高压流体进行地面改进。在注射杆的圆周上设置有径向向外延伸到注射杆的轴线的搅动叶片12，并且搅拌叶片根据注射杆的旋转而旋转。注射喷嘴设置在搅拌喷嘴的尖端部分上，并且包括朝向喷射杆打开的喷嘴口。在与注射棒分离的区域中，考虑到地面被高压喷射搅拌，并且当搅拌叶片旋转时扭矩与中心部分的距离成正比，作用在尖端附近的扭矩的搅拌叶片可以最小化。

摘要： PROBLEM TO BE SOLVED: To provide a supporting structure of a foundation pile capable of ensuring the effective load transfer to a foot protection section from a pile body and to the bearing ground to exhibit high bearing power and having the excellence in workability at a low cost and a steel pipe pile. SOLUTION: The supporting structure of the foundation pile is constituted of the steel pipe pile having a circular or a spiral projection 2 on the outer circumference of the front end section and the foot protection section 11 formed in a bearing layer in the ground or an area including the bearing layer, and it fulfills the following conditions. [p/h=8 to 15], [H≤S1+S2], [Dp×2≥Dg≥Dp+2×h]. Here, p is the pitch of the projection 2, H is the overall height of the foot protection section 11, Dp is the external diameter of the steel pipe pile 1, and Dg is the external diameter of the foot protection section 11. S1 is the anchorage length of the circumferential projection, S2 is the distance from the front end of the steel pipe pile to the bottom of the foot protection section, and it fulfills the following conditions. [1.75×Dg-2.45×Dp≤S1≤1.75×Dg-1.75×Dp], and [Dp×2≥S2≥(Dg-Dp)/(2×tanβ)]. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a soil improvement body creating equipment and its method capable of definitely creating the soil improvement body with specified size and material. SOLUTION: This equipment comprises an inlet rod 11 equipped with an inner pipe as a passage for a high pressure fluid, injection nozzles 20, 21 and agitating wings 12, and the soil improvement body is created by injecting a hardened material into ground while rotating and moving the injection rod back and forth. In this case, a diffusion prevention plates 14 for interrupting the scattering path for the hardened material injected under high pressure from the injection nozzles 20, 22 are attached to the tip of the agitating wings 12.
