Description
Technical Field
The invention relates to the technical field of tubular pile material distribution, in particular to a tubular pile weight distribution online monitoring method, a tubular pile weight distribution online monitoring device and application.
Background
The concrete pipe pile is formed by mixing and coagulating cementing materials, granular aggregates (also called as aggregates) such as stones, sands and the like and other auxiliary agents. The strength of the tubular pile is determined by the distribution of the reinforcing steel bars and the aggregates, and the strength is high in a place with more aggregates and is weak in a place with less aggregates because the distribution of the reinforcing steel bars is fixed. In the using process of the tubular pile, the strength grade of the tubular pile is based on the weakest strength of the tubular pile, so the uniformity of the distribution of materials in the tubular pile is very important for the strength and the quality of the final tubular pile.
The production process of the concrete pipe pile comprises the steps of formwork supporting, filling, die assembly, centrifugation and solidification forming. In the prior art, the uniformity of mixed materials is improved mainly by a centrifugal process. However, although the uniformity of material distribution can be improved by prolonging the centrifugation time, the centrifugation time is not suitable to be too long because the setting time of the cementing material such as cement is limited, and meanwhile, aggregates such as stones and sands are gradually moved outwards in the radial direction in the centrifugation process due to the heavy weight, the central strength is insufficient due to the too long centrifugation time, and although the aggregates are moved in the horizontal direction in the centrifugation process, the centrifugation needs to be stopped because the aggregates are not completely uniform due to the limited centrifugation time, so that the improvement of the uniformity of mixed materials by only the centrifugation process is very limited.
On the other hand, the degree of difficulty of centrifugation is reduced through controlling the cloth degree of consistency in the filling process, so that the purpose of improving the degree of consistency of the mixed material of the tubular pile is achieved. In the filling process, the distributor truck distributes concrete into the pipe die, and the weight of the distributed concrete is generally controlled by the following methods:
a. manually moving the distributing flat car, and placing concrete into the pipe die by manually observing and combining the weight of each car of the distributing car;
b. calculating the material distribution amount by calculating the weight reduction amount of concrete on the material distribution vehicle through a weight sensor arranged on the material distribution vehicle;
however, because the length of the pipe die is long, and generally reaches several meters to twenty meters, the method can only know the weight increase value of the cloth in the pipe die, but does not know the distribution of the increased weight in the pipe die, so that the cloth is difficult to be uniformly distributed to each pipe section of the pipe die, and the situations of local material shortage and local material accumulation are easy to occur in the actual production.
