Background
Under the current situation, the embedded bars in the national standard and the process method require the original concrete base surface to be dry, and the national standard has clear requirements on the water content of the concrete, but in actual construction, the embedded bars are often required in a humid environment.
The existing bar planting process comprises the following steps: and (3) bar planting: and (3) drilling holes on the concrete base material by using an electric drill, and implanting the reinforcing steel bars with the new structure into the original concrete for connecting the new and old concrete structures. Hole cleaning: after the concrete base material is drilled, dust in the hole, loose aggregate caused by drilling and the like need to be cleaned. Injecting glue: structural glue is injected into the holes.
As a new reinforcing technology, bar planting is widely used in reconstruction and reinforcement of industrial and civil buildings, and at present, the bar planting in a dry environment has mature theory and practical experience, but when the concrete is wet and has water, the concrete water content treatment can be firstly carried out and then the bar planting can be carried out.
However, in the basement of the tail building of some projects, underground open water is abundant, drainage is not easy, but ribs must be planted in a humid environment due to shortage of construction period. Although the market has a structural adhesive applicable to a humid environment, the structural adhesive has no related construction method and standard guidance construction, and the normal construction process is not applicable, so a new construction bar planting construction method is needed to guide construction in a humid or open water environment.
