Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge engineering construction, in particular to a support cushion stone safety protection operation trolley. Background Art

[0002] In the construction of the cap beam support pad stone, the construction of the cap beam pad stone requires construction workers to go up to the top of the cap beam to tie the pad stone steel bars and pour the concrete. Since the cap beam is a high-altitude operation and the surface area of ​​the cap beam is small, there are no edge protection measures around it, and the personnel are in an unprotected state. Since the top surface of the cap beam is small for construction workers to stand, it is dangerous and prone to safety accidents of falling from height. Later, in order to eliminate the risk of falling from height and ensure the safety of high-altitude workers during the construction process, construction guardrails are usually installed on the cap beam. However, the existing construction guardrails are fixed, and expansion bolts are inserted into the cap beam concrete for fixing. When disassembled, the expansion bolts will seriously damage the cap beam concrete, and the construction workers need to repair the concrete of the cap beam later. However, the fixed width of these construction guardrails cannot meet the construction requirements of different sizes of cap beam support pad stones, and they need to be disassembled and installed back and forth. At the same time, the existing construction guardrails are difficult to move after installation. During construction, multiple groups of construction guardrails are generally required to be built, which increases construction costs and transportation costs. The efficiency is low and is not conducive to batch construction. Therefore, in order to avoid the shortcomings of the prior art, it is necessary to improve the prior art. Utility Model Content
