Description
Technical Field
The utility model relates to an environment-friendly protection shed, in particular to a shaped assembled environment-friendly protection shed, and belongs to the technical field of protection sheds.
Background
The foundation and foundation project are short in construction period, the temporary protection shed is generally adopted for processing and manufacturing reinforcing steel bars and using cement, lime and the like in the open air, namely the steel pipe scaffold is temporarily erected, and the color strip cloth and the plastic paper are covered. From each construction process contrast of company's undertaking project, the reinforced concrete bored concrete pile construction process is more big at the protection canopy and is set up the degree of difficulty, because need weld the steel reinforcement cage, the span of setting up of protection canopy is big, and under the prerequisite that does not influence steel reinforcement cage processing moreover, inside still need be equipped with the console mode welding smoke purifier smoke absorption device of a certain amount. Therefore, other processes can be adopted as long as the process is satisfied. In the implementation of the project of the pile foundation in the third period of China century city, the temporary protection shed designed by the project department is set up as an environmental protection inspection target in the jurisdiction by a comprehensive law enforcement team due to the set-up appearance and corresponding measures, but the temporary protection shed still has the following problems through the project practice:
1. structural stability:
