Description
Technical Field
The invention relates to the technical field of pipe pile distribution, in particular to a pipe pile weight distribution on-line monitoring method, a device and application.
Background
The concrete pipe pile is formed by mixing and coagulating granular aggregates (also called aggregates) such as cementing materials, stones, sand and the like and other auxiliary agents. The strength of the pipe pile is determined by the distribution of the reinforcing steel bars and the aggregates, and the distribution of the reinforcing steel bars is fixed, so that the strength is high at the position with more aggregates and weak at the position with less aggregates. In the use process of the tubular pile, the strength grade of the tubular pile is based on the weakest strength of the tubular pile, so that the uniformity of distribution of each material in the tubular pile is important for the strength and quality of the final tubular pile.
The production process of the concrete pipe pile comprises the steps of formwork supporting, filling, mould closing, centrifugation and solidification forming. In the prior art, the uniformity of the mixed materials is improved mainly through 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 cementing materials such as cement is limited, and aggregates such as stones and sand can gradually move outwards along the radial direction in the centrifugation process due to heavier mass, the centrifugation time is too long, so that the center strength is insufficient, and the aggregates can move along the horizontal direction while being centrifuged, but the centrifugation is stopped because the aggregates are not completely uniform due to the limitation of the centrifugation time, so that the improvement of the uniformity of the mixed materials is limited only by a centrifugation process.
On the other hand, the centrifugal difficulty is reduced by controlling the distribution uniformity in the filling process, so that the aim of improving the uniformity of the tubular pile mixing is fulfilled. In the process of filling, a distributing car distributes concrete into a pipe die, and the following methods are generally used for controlling the weight of the distribution:
a. manually moving the material distribution flatcar, and placing concrete into a pipe die by manual visual observation and combining the weight of each material distribution car;
b. calculating the distribution amount by calculating the weight reduction amount of the concrete on the distributing vehicle through a weight sensor arranged on the distributing vehicle;
however, since the length of the pipe die is long, generally reaching several meters to twenty meters, the method only can know the added value of the weight of the material in the pipe die, but does not know the distribution of the added weight in the pipe die, so that uniform material distribution to each pipe section of the pipe die is difficult, and the situations of partial material shortage and partial material accumulation easily occur in actual production.
