Analysis of Combined Support Technology with U-Shaped Steel Bracket and Anchor Bolt

Abstract

This paper synthetically analyzed essential features of various support methods in engineering geological soft rock, proposed a scheme that organically combines active support (like anchor bolt support) with passive support (like U-shaped steel bracket support), analyzed fundamentals of this combined support scheme, and forecasted support effect of this support scheme. It provides roadway support design with fresh ideas. U-shaped steel bracket can be translated into special anchor plate with the help of a section of simple steel channel beam, so effect of anchor bolt can be ensured; U-shaped steel bracket , this extremely long curved beam ,will be divided into several sections of short beams, so its bearing ability will be several times improved. Cost of this combined support scheme is low, its process is simple and its application prospect is wide.
