Description

Technical Field

[0001] The utility model relates to the field of supporting devices, in particular to a supporting device for a composite soil nail wall. Background Art

[0002] Composite soil nail wall is a high-strength wall structure made of composite materials, used for the load-bearing wall of a building. It is composed of reinforced concrete and the outer surface is covered with a layer of glass fiber reinforced composite material or carbon fiber reinforced composite material. The support device for the composite soil nail wall is a device specially used to support and protect the composite soil nail wall structure during the construction process, ensuring that the composite soil nail wall is stable and reliable during the construction process to prevent safety accidents such as tilting and collapse. In the existing support device, integrated steel pipes and steel beams are usually used for stable support during the support process. Due to the fixedness of steel pipes, when fixing soil nail walls of different heights, multiple groups of steel pipes are required to be combined with bundled supports. The combined bundled supports of multiple groups of steel pipes need to be installed and disassembled multiple times, and the construction process is relatively complicated. At the same time, multiple adjustments are required to ensure the stability of the support, increase material costs and construction costs, and reduce the installation efficiency of the support device. Therefore, we propose a support device for composite soil nail walls to solve the above-mentioned problems. Utility Model Content
