The basic requirement of the ring active protective net project is that the design shape, size and position of each part of the concrete structure and protective net should be correct.
The ring active protective net should have enough strength, stiffness and stability to withstand various construction loads and ensure the deformation within the allowable range. The surface of the panel should be smooth and smooth, with tight seam and no leakage.
Installation and disassembly are convenient and safe, and can be used many times. Standardization and serialization should be achieved as far as possible, and the selection of circular protective net should be suitable to the characteristics of concrete structure and protective net, construction conditions and pouring methods.
The quality of annular protective mesh materials should meet the current national standards and industry standards: when using steel, it is appropriate to use Q235 steel, its quality should comply with the GPS2 active network cost budget is how much the relevant provisions.
