Document Type and Number:
WIPO Patent Application WO/2017/116017
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing an ultra-high strength steel pipe support using a boron steel, and a support assembly, and according to one embodiment of the present invention, a support provided for preventing the collapse of bedrock, an inclined plane, and the like is molded and manufactured as a steel pipe by a steel sheet to which boron is added, thereby being able to withstand a great load and being capable of remarkably lowering the possibility of damage. In addition, since the support is formed in a hollow structure, manufacturing and production costs can be reduced because of a reduction in weight, and there is an effect of enabling the support to be prevented from being deviated toward the outside from the inside of a perforation formed in bedrock or on an inclined plane, and the like. Moreover, since mortar is injected into the perforation through the support, workability can be improved.
