Description

Production process and production equipment of environment-friendly reinforced concrete pipe
Technical Field
The invention relates to the technical field of concrete pipe processing, in particular to a production process and production equipment of an environment-friendly reinforced concrete pipe.
Background
The cement concrete is the most widely applied engineering material, a large amount of natural resources are consumed in cement production, and the popularization of the green high-performance concrete is an important way for realizing sustainable development. The main raw material in the tubular pile industry is also cement concrete, and aiming at the characteristics of the tubular pile industry, the development of green concrete is started from the following aspects: research and utilization of industrial waste residue fine admixture to reduce cement consumption; reasonably selecting an additive; the variety, the using amount and the doping amount of the reinforced fiber are reasonably selected, so that the environment-friendly effect is realized;
in the process of producing concrete pipes at the present stage, the conventional production modes mainly include a centrifugal method, a vibration method, a rolling method, a vacuum operation method and a method of combined action of rolling, centrifugation and vibration. Prestressed concrete pressure pipes are being developed more in china and many other countries in order to improve the service properties of concrete pipes. The pipe is provided with longitudinal and circumferential prestressed reinforcements, so that the pipe has high crack resistance and impermeability. In the 80 s, China and other countries developed self-stressed reinforced concrete pipes, which were mainly characterized by the fact that the expansion of self-stressed cement (special cement) during the hardening process was used to generate prestress, simplifying the manufacturing process. Compared with steel pipes, the concrete pipe can save a large amount of steel, prolongs the service life, has low factory building investment and convenient laying and installation, and is widely applied to factories, mines, oil fields, ports, urban construction and farmland hydraulic engineering;
in addition, in order to improve the performance of the concrete pipe, some materials are added in the processing process of the concrete pipe to improve the comprehensive performance of the concrete pipe, for example, 1, the concrete pipe applied in a cold place needs to be added with anti-freezing gel, so that the moisture of the concrete is kept from freezing under certain stability, and the coagulation and hardening of the concrete are promoted; 2. a proper amount of sodium chloride and potassium carbonate is added into the concrete slurry to reduce the freezing point;
at present, the loading method generally adopted in the enterprise production is to weigh the raw materials in advance by a weighing tool such as a weighbridge or an electronic scale, manually adjust the weight by increasing or decreasing a certain material, and after the adjustment is completed, sequentially convey the raw materials to a stirrer by a transport tool such as a forklift to stir and mix the raw materials.
However, there are several problems with such an approach:
firstly, manual ratio adjustment is carried out, so that the efficiency is low and the precision is low;
secondly, during transportation by a forklift, raw materials are easily leaked, which causes inaccurate proportioning and
the examination environment of the workshop is polluted, and the health of workers is harmed;
thirdly, the raw materials need to be transported in sequence, and the layering phenomenon appears in the stirrer, so that the raw materials cannot be completely and uniformly mixed by virtue of the stirrer, and the production quality is affected.
