摘要： PROBLEM TO BE SOLVED: To protrude a packer speedily and easily. SOLUTION: This packer device is provided with a pouring pipe part 8 including an internal pipe 6 having a diameter expansion part 6a having relatively a large diameter in a tip side part, an external pipe 7 which surrounds the internal pipe part more rearward than the diameter expansion part 6a with a clearance and can slide freely and forward and backward along the longitudinal direction of the internal pipe 6 for the internal pipe 6, and a flexible cylindrical packer member 5P surrounding the internal pipe part between a tip face of the external pipe 7 and a rear end face of the internal pipe diameter expansion part 6a and a single operation means 9 sliding the internal pipe 6 forward and backward for the external pipe 7. When the internal pipe 6 is slid and moved backward for the external pipe 7 by the single operation means 9, the flexible packer member 5P is nipped and compressed between the internal pipe diameter expansion part 6a and the tip face of the external pipe 7 to expand and protrude it sideways.

摘要： PURPOSE:To permit sloped ground to be repaired in a short time by a simplified method in which anchors are driven into cavities formed in a slope and fixed to natural ground, and a grout is injected under pressure into the cavities from the heads of anchors. CONSTITUTION:The positions of cavities 3 formed in a slope 1 are detected by the conventional method, and slit-like line are drawn on the slope. Holes are formed in the center of the cavity 3 by drill, etc., and anchors 10 are driven through sprayed concrete 2 into natural ground. The halved tip of the anchor is expanded through draw bolts and fixed to the ground. The draw bolts are then pulled out and a grout is injected under pressure from the heads of the anchors 10 to fill the cavities 3 with the grout through the halved body. In this case, the anchors 10 are left behind under the ground.

摘要： PURPOSE:To make easier the coupling and removal operatins of tension members and load proofers by a method in which a coupler is inserted into a load proofer set in an anchor hole and then attracted or departed by operating an electromagnet. CONSTITUTION:An assembly consisting of a bottomed pipe 3, a concrete pipe 4, and sheath as a load proofer is inserted into an anchor hole. Then, a groove 3a as a coupling step is formed on the inner face of the pipe 3, and a concaved portion 7a for housing purpose is formed on the circumferential part of the tip of a coupler 7 and housed with a coupling piece 8 of magnet. The coupling piece 8 is housed in the concaved portion 7a and inserted into the receiving hole 3b of the pipe 3, and then electricity is supplied to a coil 10 through a conductor 9 to generate a magnetic force. By this, the coupling piece 8 is projected from the concaved portion 7a and fitted into the groove 3a for coupling. Under the condition, tension members are tensed and fixed. In the removal of the tension members, the tension of tension members is released, a reverse current is flowed in the coil 10, and the coupling piece 8 is attracted and released from coupling.

摘要： PROBLEM TO BE SOLVED: To increase a strength of a pile and prevent the corrosion of a steel core material in the pile. SOLUTION: A pile installation ground is drilled to a specified depth, as necessary, using a casing 15 so as to form a pile installation hole (h). Next, a steel tube body 12 of tip sealed type user as a rust preventive case is inserted into the center of the pile installation hole (h), grout material (13) is filled between the steel tube body 12 and an installation hole wall (not penetrated from the hole wall into the ground), and the casing 15 is extracted. Then, a steel core material 1 is inserted from a base end opening into the steel tube body 12, and grout material 14 is filled between the outer surface of the inserted steel core material 1 and the inner surface of the steel tube body 12. A pile body is created by the hardening of these filled grout materials 13 and 14.

摘要： PURPOSE:To obtain the desired strength at anchored state and reduce the strength when unnecessary by a method wherein a hollow member, which is unable to bear by itself the load supposed to be withheld when it is anchored, is reinforced by the insertion thereinto reinforcing member. CONSTITUTION:An anchor hole 1 is drilled in the ground concerned. The said anchor hole is provided with vinyl chloride hollow member 2 into which are inserted reinforcements 5 including PC steel bars and tension members 3 made of stranded PC steel wire. Then the remaining space of the anchor hole 1 is filled with hardening material 4 such as mortar. The outside of the hollow member 2 is provided with hard rubber spacers 6 and bands 7. The tension members 3 are mounted on the outside of the spacers 6 and on the inside of the bands 7. When anchoring the said hollow member, an anchorage is provided on its bottom to strain the tension member 3. When removing the said hollow mem- ber, the reinforcements 5 is withdrawn to pull the tension member 3 in the arrowed direction so that it may be straightened to destroy the hollow member 2. The bonding strength of the tension member 3 and that of the material 4 is weakened to provide ease of withdrawing the tension member 3.
摘要翻译：目的：为了在锚定状态下获得所需的强度，并且当通过其中不能承受锚定时应该被扣留的载荷的中空构件不需要时，通过将其插入到加强构件中来加强，。构成：在有关地面钻出锚孔1。所述锚孔设置有氯乙烯中空构件2，其中插入有包括PC钢条的加强件5和由绞合的PC钢丝制成的张紧构件3。然后，锚固孔1的剩余空间填充有诸如砂浆的硬化材料4。中空构件2的外侧设置有硬橡胶隔离物6和带7.张紧构件3安装在间隔件6的外侧和带7的内侧。当锚固所述中空构件时，锚固件设置在其底部以应变张紧构件3.当移除所述中空构件时，将加强件5拉出以沿着箭头方向拉动张紧构件3，使得其可以被拉直以破坏中空构件2。张力构件3的强度和材料4的强度被削弱以提供拉伸构件3的容易性。

SOLUTION: A tubular anchor member 1 having a tip bit 1B and air discharge ports BH1-BH3 is provided. The natural ground BG on the back is bored by the tubular anchor member 1 through an existing lining object C1, and the tubular anchor member 1 is inserted into the natural ground BG except for its head section 1H through this bored hole. When the insertion through the bored hole is completed, the tubular anchor member 1 is left in the natural ground BG without being extracted, and the head section 1H is fixed to the surface of the existing lining object C1 to firmly integrate the natural ground BG and the existing lining object C1. A tubular body can be inserted easily and smoothly, and work efficiency can be improved.
