The present invention provides an anchor pile and installation method for the same, which includes insertion hole portions and guide portions formed in the side surface of a hollow pipe. In a state where a resistance member formed of a material that can be elastically deformed is stored within the pipe, the anchor pile is driven into the ground. When an auxiliary tool is used to pull up the resistance member in a vertical direction within the pipe after the anchor pile is driven into the ground, the protrusion portions of the resistance member slide on the guide portions and are deformed so as to be opened and extended toward the insertion hole portions. The protrusion portions of the resistance member are protruded from the insertion hole portions toward the ground and function to provide the resistance force of the anchor pile in the ground.

An expandable stake assembly for securing a temporary structure to ground includes a stake that may be inserted into ground. An attachment is rotatably coupled to the stake and a securing line may be attached thereto for securing a structure to the ground. A sleeve is provided and the stake extends therethrough. The sleeve is expandable to extend outwardly from the stake when the stake is inserted into ground. Thus, the sleeve inhibits the stake from being removed from the ground.

The tie rod for structural projects for the protection of structures for earthquake and wind is comprised of a cast iron base (7) which has a bolt (4) passing through a hole, which is surrounded by threaded ring (5) with handles (6). A base plate (2) that sits on the bolt and turns with a ball bearing. A steel cable (9) passes through all; the one end of the cable is fixed to the base (2) with bolts (3). The other end leads to a member with blades around it (10), (12), (13), (14) which open and close around the member (17) with the help of bars (11) connected around the axis of the member with pins. To the other end, they are connected with pins to the blades. The rod presses the structure to the ground by a bolt connected to a cable which pulls a member (17) with blades which open against the sides of a hole drilled on the ground and pull the building towards the ground decreasing torque created by the forces of an earthquake or the wind. It is used on buildings with a frame, continuous building, wood frame houses with storm problems, cable bridges, loose ground slopes, etc.

A tool for an offshore wind power foundation pile includes a steel pipe pile, a pile core, a pile cap, and a pile shoe. A cutting shoe portion is arranged at a bottom of the steel pipe pile, and an outer diameter of the pile shoe is larger than an outer diameter of the cutting shoe portion; the pile cap is detachably connected to the top of the steel pipe pile; the pile core is located in the steel pipe pile, the pile core is detachably connected to the pile shoe, and a length of the pile core is larger than or equal to a length of the steel pipe pile; the pile cap is further provided with a pile core accommodating groove and a pile core limiting portion; the pile core limiting portion includes a pile core limiting block and a limiting hole.

A guy wire anchoring device is provided which can be used to hold a tower in place. The device features a container which has a plurality of solid side panels, which are connected to two adjacent side panels using a side hinge mechanism. As a result, the container can be reversably moved from an essentially flat, folded orientation, to an expanded empty container orientation when un-folded. The container also includes at least one base plate which is hingeably mounted to the lower edge of at least one side panel of the container, and which can be moved to a position wherein it at least partially closes the opening at the bottom of said empty container. The container is adapted to be filled with a suitable, local material such as sand, aggregate, or the like, in order to increase the weight of the guy wire anchoring device. The device includes a guy wire anchoring bracket to which guy wires can be attached. The device is easily stored, and can be easily transported to the tower location for use as a guy wire anchoring device.

The present invention relates to an earth retaining structure for reinforcing a slope, and more particularly, to an anchor including a fixing body at a pressure plate side for compressing a slope and a method for installing the anchor in the slope. The anchor including a fixing body at a pressure plate side for compressing a slope capable of preventing tension of the anchor from being lost by installing a friction type pressure plate fixing body in a steel pipe form that is integrated with the pressure plate at the pressure plate side of the anchor, installing a primary packer at a middle part of the anchor to conduct pressurized-grouting to fix a tip end side fixing body of the anchor, compressing a large pressure plate compressing the slope by introducing a tensile force to the tension member of the anchor together with the pressure plate side fixing body, expanding a secondary packer, and conducting secondary pressurized-grouting, is provided.

Provided is a ground reinforcement structure installed on a ground (10) in which a sandy soil layer (11) having a weak surface layer is provided and thus large-caliber excavation is difficult to be performed, the ground reinforcement structure including a ground reinforcement material (100) including: an expansion-type steel pipe (110) inserted to be installed in a small-caliber drilled portion (A) having a diameter of 51 mm to 61 mm and expanded by hydraulic pressure; and a settlement member (120) coupled to a rear end of the expansion-type steel pipe (110). Here, the expansion-type steel pipe (110) is inserted into the sandy soil layer (11), and the settlement member (120) is inserted into a rock layer (12). In this case, the settlement member (120) of the ground reinforcement structure according to the present invention is fixed to the rock layer (12), fixing force is excellent.

A ground anchor system configured for introducing into a borehole, and comprising a plurality of straps each having a length dimension extending along a central longitudinal axis of the ground anchor system. Each of said straps has a width dimension taken along a major axis and a thickness dimension taken along a minor axis. The major axis and the minor axis are disposed at a transverse plane of the ground anchor system and intersect at a middle point. The middle point of each of said straps is intersected by an imaginary line extending through the longitudinal axis at the transverse plane. The imaginary line forms an angle smaller than 90 with the major axis of the respective strap.
