Structure of falling is prevented in steel shotcrete in SMW worker method stake envelope foundation ditch

The utility model relates to a structure of falling is prevented in steel shotcrete in SMW worker method stake envelope foundation ditch connects installation wire rope between the tip of steel shotcrete is rather than the hole for hoist of adjacent H shaped steel. The utility model discloses utilize SMW to be good at method H stake shaped steel up -pull and insert the hole for hoist that shaped steel was used, adopt wire rope to bind the steel shotcrete and suspend in midair, ensure that the steel shotcrete changes perhaps equipment collision is followed has wire rope after the support position drops secondary protection at the atress, can guarantee the safety of steel shotcrete. 本实用新型涉及种SMW工法桩围护结构基坑中钢支撑防坠落结构，在钢支撑的端部与其相邻的H型钢的吊装孔之间连接安装钢丝绳。本实用新型利用SMW工法H桩型钢上拔插型钢用的吊装孔，采用钢丝绳对钢支撑进行捆绑悬吊，确保钢支撑在受力变化或者设备碰撞从支座位置脱落后有钢丝绳的二次保护，能够保证钢支撑的安全。
