The present invention relates to an anchor that binds a tension member of an anchor system installed in civil engineering or building structure construction and is anchored in the ground. In particular, a tension member removal type capable of separating a tension member from an anchor by removing a binding force that binds the tension member. It is about anchors.

First, the construction method of the conventional anchor system is briefly described.

An anchor system is a fixing device installed in civil engineering or construction building construction and is installed to support the earth wall and to install the earth wall for the construction of underground structures or to prevent surrounding settlement during the excavation.

However, when removing the tension member, a separate drawing equipment is required and a lubricant is required to smoothly pull out the tension member. Do.

However, the lubricant has a problem that damages the environment by polluting the soil and ground water.

In particular, the tension member removal anchor using the repulsive force generated when the tension member is removed can maintain the binding force of the tension member and secure mechanical stability before mounting the anchor by using a spring that is not compressed below a predetermined action force, but the support force of the spring Due to this strong relationship, if the repulsive force is not formed as much as desired, the spring is not compressed, and thus the binding force for binding the tension member is maintained, so that the tension member is not removed, and in particular, the tension member is connected to the earth wall or other equipment. Since the steel wire of the tension material consisting of a plurality of steel wires are removed by strands without removing all of the tension material at the same time, the repulsive force weakens frequently, so that the binding of the anchor does not loosen, and thus the binding from the anchor is not released. If not a predetermined device ie hammer There is a problem to remove the binding of the anchor by using a hammer.

The present invention has been made in order to solve the above problems to form a groove according to the combination of the cylinder and the cap forming the appearance of the anchor to the anchor provided by the towing unit fixed to the groove by an external impact, etc. To prevent separation of the tension member, and after tensioning of the tension member, the tensioning plate decreases when tensioning the tension member, and the towing part is moved to remove the fixing ring to separate the tension member. have.
