Abstract
The present invention relates to a shock absorber for a ground anchor, and more particularly, to prevent the collapse of the steel wire by installing a shock absorber to prevent the short circuit of the steel wire to absorb the shock impinged on the steel wire at the end of the steel wire. A shock absorber for ground anchors.
The conventional ground anchor is a structure in which all the pressures due to the shaking of the ground due to ground movement or explosive blasting due to an earthquake are transferred to the steel wire as it is. When the accident is generated, the present invention and the anchor body is fixed to one end of the steel wire; In the configuration of the anchor head which is coupled to the other end of the steel wire, by providing a shock absorber to prevent the short circuit of the steel wire to absorb the shock impinged on the steel wire at the end of the steel wire, the external impact is transmitted to the steel wire When the steel wire is stretched, the shock absorber installed at one end of the steel wire absorbs and absorbs the shock due to elongation, thereby preventing the collapse accident that may occur due to the short circuit of the steel wire.
Description
The present invention relates to a shock absorber for a ground anchor, and more particularly, to prevent the collapse of the steel wire by installing a shock absorber to prevent the short circuit of the steel wire to absorb the shock impinged on the steel wire at the end of the steel wire. A shock absorber for ground anchors.
Ground anchors are very useful for stabilizing slopes and reinforcing methods such as retaining walls or revetment structures, which have a high risk of collapse during ground excavation, site construction and road construction.
As is well known, the ground anchor secures the stability of the structure by applying a restraint force or a transverse load in the transverse or vertical direction to the structure through the frictional resistance or the pressure resistance between the structure and the ground by fixing it between the structure and the ground. Prestress minimizes the deformation of the surrounding ground.
These ground anchors are similar to the piles in that the structure is fixed to the ground through the tension member. However, the ground anchors are different from the simple support piles in that the ground anchors are fixed by applying tension in advance to reduce the displacement of the structure. There is this.
That is, the ground anchors form holes in the back ground of the retaining walls, insert the anchors connected to the steel wires, and inject concrete into the holes to allow the steel wires to support the retaining walls.
1 is a cross-sectional view showing a construction example of a general ground anchor.
As shown in FIG. 1, a hole 200 is formed in the bottom surface of the retaining wall 100, the anchor body 1 connected with the steel wire 3 is inserted into the hole 200, and then the hole 200 is formed. Inject the concrete 300 into the interior to cure.
When curing of the injected concrete 300 is completed, the barrier wall 100 can counteract the pressure of the soil by tensioning the steel wire 3 exposed to the outside of the barrier wall 100 and fixing it to the anchor head 4. It is.
The conventional ground anchor is a structure in which all pressures due to the shaking of the ground due to the ground movement or explosive blast caused by an earthquake are transferred to the steel wire as it is. Accident occurs.
The present invention relates to a shock absorber for a ground anchor, and more particularly, to prevent the collapse of the steel wire by installing a shock absorber to prevent the short circuit of the steel wire to absorb the shock impinged on the steel wire at the end of the steel wire. The object is to provide a shock absorber for the ground anchor.
The present invention in order to achieve the object as described above is anchored to one end of the steel wire is fixed; In the configuration of the anchor head coupled to the other end of the steel wire, the end of the steel wire is characterized in that the shock absorber to prevent the short circuit of the steel wire to absorb the shock impinged on the steel wire.
According to the present invention configured as described above, when an external shock is transmitted to the steel wire and the steel wire is stretched, the shock absorber installed at one end of the steel wire absorbs and absorbs the shock according to the elongation, thereby preventing the collapse of the steel wire. Will be done.
1 is a cross-sectional view showing a general ground anchor.
Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
As shown in the accompanying drawings, the present invention and the anchor body is fixed to one end of the steel wire; In the configuration of the anchor head to which the other end of the steel wire is coupled, the end of the steel wire is configured to install a shock absorber to prevent the short circuit of the steel wire to absorb the shock impinged on the steel wire.
The shock absorber may be composed of an elastic body coupled to the end of the steel wire.
In addition, the elastic body may be composed of a first elastic member and a second elastic member.
The first elastic member is composed of a high strength urethane, the second elastic member is composed of a compression spring.
The shock absorber is provided with a pressure plate having a through hole through which the steel wire penetrates on one side of the pipe, and installs a first buffer member and a second buffer member inside the pipe, and the first buffer member on the other side of the pipe. And a support plate for supporting the buffer members while the steel wire penetrates the second buffer member and a fixing clip coupled to the steel wire penetrating the support plate.
