Measures to absorb the impact of anchor head protrusion in the event of anchor breakage due to aging or other factors. Maximum protrusion energy up to 64 kJ.
This construction method absorbs the impact of anchor head protrusion in the event of breakage due to forces exceeding expectations or aging, ensuring the safety of social infrastructure such as human life and road traffic. By covering the ABOXX main body with the anchor head, protrusion is prevented. The capture performance of the anchor head has been verified through full-scale experiments and numerical analyses based on these experiments, capable of handling a maximum protrusion energy of 64 kJ. 【Applications】 ● Measures against protrusion of existing anchors that may be aging or at risk of ground deformation. 【Features】 ● The ABOXX main body is pre-assembled and lightweight, making installation easy. ● It can be constructed in a short period without the need for skilled workers. ● As it absorbs energy while deforming, it can reduce the force acting on the frame anchor for shock-absorbing components (spring brakes). ● Four types of combinations with different component configurations are available according to the design energy.

Company information
Since its establishment, our company has played a role in national construction, primarily focusing on the "ground improvement field" with our unique grouting method. Subsequently, in response to the changes in social infrastructure development, we have refined our technologies to adapt to the needs of the times and, at times, acquired new ones to expand our business scope. As a result, we have now established three main pillars: "ground improvement business," "slope disaster prevention business," and "pipeline business."
