摘要:
A friction bolt including an elongated metal tube and a plurality of friction members. The metal tube includes interior and exterior surfaces, a tapered distal end portion, a proximal end portion, and a slit extending along a length of the elongated metal tube. The plurality of friction members extend outward from the exterior surface, and at least some of the friction members have an exposed planar portion to frictionally engage an inner surface of a bore within which the friction bolt is inserted.

In general, embodiments of the present invention relate to ground anchor assemblies. Specifically, the present invention provides a multi-stage extending ground anchor assembly including wing members that are coupled to a fixing member of the ground anchor assembly. The wing members are configured to make contact with an inner wall of a ground hole such that the earth anchor assembly can be used in surfaces of any consistency, including both bedrock and soft surfaces.

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 constant-resistance large-deformation anchor rod includes a rod body (6), a tray (3), a nut (2), and a constant-resistance device (4). The constant-resistance device (4) is formed into a cylindrical structure, and the inner surface of the constant-resistance device (4) and the outer surface of the rod body (6) are both formed with thread structures. The constant-resistance device (4) is sleeved at the tail of the rod body (6), and the tray (3) and the nut (2) are sequentially sleeved at the tail of the constant-resistance device (4). The nut (2) is in threaded connection with the constant-resistance device (4). The constant-resistance large-deformation anchor rod in the invention can be automatically stretched when the tunnel surrounding rock deforms largely, and keep the constant working resistance.
摘要:
An anchoring base for a delineating pole using the reconfiguration of protruding resilient mechanical members to facilitate insertion and resist the subsequent extraction force on the pole. The mechanical members extend outwards relative to the insertion rod longitudinal axis, and bend or configure upon insertion of the anchoring base, into a first position that facilitates insertion while impeding and resisting axial extraction forces, and upon subsequent rotation of the anchoring base, the mechanical members bend or reconfigure into a second position such that the extraction resistance force is significantly reduced. The anchoring base design may be used in conjunction with a spring cartridge having a plurality of interlocking members forming a rigid mechanical structure during rotation.
摘要:
An erosion control system for reducing erosion under effluent flow conditions. The system includes an erosion control mat anchored over an erosion susceptible area. The anchoring system uses an anchor positioned below the soil, connected to the mat by a flexible strap. Due to its high shear resistance, the system may be used in high effluent flow areas, such as drainage ditches and creeks.

The present invention provides an internal fixer for an anchor having a releasable tensioning steel wire. The internal fixer of the present invention includes a first outer body (10), which is provided with a tube coupling hole (11), a body seating hole (13) and a wedge receiving body support means; and a wedge receiving body (30), which is seated in the body seating hole (13) and has a conical wedge seating hole (31), into which separated wedge bodies (41) are seated. The internal fixer further includes a wedge unit (40), which is seated in the wedge seating hole (31) of the wedge receiving body (30) and comprises the three separated wedge bodies (41); and a second outer body (20), which supports and covers both the wedge receiving body (30), which is seated in the body seating hole (13), and the wedge unit (40), which is placed in the wedge seating hole (31).
摘要:
The present invention relates to an anchoring stake that includes an elongate member having a longitudinal axis extending along its longitudinal length, the elongate member having a lower portion which is insertable into a ground environment and an upper portion which in use projects above the ground environment, and at least one anchor member attached to the lower portion of the elongate member. The anchor member is movable between an insertion position in which the length of the at least one anchor member is generally aligned with the longitudinal axis of the elongate member and an anchoring position in which the length of the at least one anchor member extends at an angle away from longitudinal axis of the elongate member.

A conventionally available pile for civil engineering work is constructed such that the pile has in its inside a core body with wedges that stick into soil deep in the ground and function to prevent the pile from coming out of place. A problem exists with such a pile in that placing the core body at an appropriate position inside the pile is difficult. A pile for civil engineering work of this invention enables a core body to be placed at an appropriate position and labor required for the placement to be reduced. A pile (1) for civil engineering work is characterized in that, for example, a guide rail (4) that enables a core body (6) to be guided is provided inside a body of the pile (1), the core body (6) is guided through the guide rail (4), and wedges (6a, 6b) are appropriately guided to cut/pushed-in openings (2a, 2b, 3a, 3b).
摘要:
Anchoring devices for securing diverse types of structures to the earth or soil, or to rock walls and formations, such as are frequently employed for anchoring gas and petroleum-product pipelines, guy-supported towers, utility poles, large-sized retaining walls and building foundations, among numerous other types of application. In order to render each of the above-described anchoring devices more user-friendly and compatible with the environment, while facilitating the installation thereof in the applicable bore holes, drilled holes or earth trenches, while also reducing the production and assembling steps required in the manufacture of the various anchoring devices, a suitable retentive encompassing packaging structure tightly encases each of the anchoring devices which will maintain the components of the respective anchoring devices in their assembled pre-installed and retracted condition.
