High-strength reinforced concrete pipe piece pouring and compacting method based on directional vibration

Abstract

The invention relates to the technical field of automatic control of concrete construction, in particular to a high-strength reinforced concrete duct piece pouring and compacting method based on directional vibration, which comprises the following steps: step 1, region division: according to the distribution density and structural complexity of reinforcing steel bars in an inner cavity of a duct piece mold, constructing a duct piece mold; the main reinforcing mesh area, the embedded part dense area, the chamfering area and the mold corner area are divided into at least two of the main reinforcing mesh area, the embedded part dense area, the chamfering area and the mold corner area; a plurality of attached vibrorammer bodies are installed on the outer side wall of the duct piece mold, each vibrorammer body is arranged corresponding to one area, and the installation position of each vibrorammer body is determined through vibration force field simulation; according to the method, the main reinforcing mesh area, the embedded part dense area, the chamfering area and the corner area are scientifically divided, finite element analysis software is combined to simulate a vibration force field, the arrangement position of a vibrator is optimized, it is ensured that vibration energy covers 90% or above of the size of a target area, and vibration blind areas are remarkably reduced.
