Description

Dry and wet agitation apparatus {An agitation apparatus for mixing}

       The present invention relates to dry and wet agitation apparatus, and more particularly, various soils or loess on granules having a small particle size including sand and gravel, asphalt, cement, which are general construction materials used for road pavement, various civil works, and construction building construction. It relates to dry and wet stirrer that can safely mix and stir evenly.

       In general, there is a great demand for general construction materials and framing in large-scale civil engineering works, including the construction, extension and restoration of roads. Among them, cement concrete and asphalt aggregates, and eco-friendly soil pavement, among other things, it is important to quantitatively mix the materials used and put them into the construction site in a timely manner, which is important to the construction quality, air and construction completeness, and various costs and costs. It is meant to be directly related.

      Recently, global warming is accelerating due to the increase of carbon dioxide, which causes disturbance and destruction of natural ecosystems.

      In fact, when looking at the concrete pavement state of the highway, high-pass section, bridge section, there are many traces of repair construction. Although concrete roads have a relatively long lifespan, maintenance costs are reduced, but they are acidified by deterioration with sodium chloride, which is a winter snow remover. As it continues to degrade, the interior below the road surface can become voided. In fact, the places repaired by squares around the concrete roads are repaired with super hard bore material due to the weakened strength due to the deterioration of concrete. Asphalt roads have relatively good riding comfort and easy maintenance, but require frequent maintenance, resulting in excessive maintenance costs and low economical efficiency.

      On the other hand, eco-friendly soil pavement has the advantage of creating a pleasant environment by reducing the queue around the pavement by blocking solar radiant heat emitted from existing roads. Maintains anti-slip function and has strong durability and abrasion by inherent elasticity of soil. Soil pavement is neutralized pavement and does not deteriorate like concrete pavement. Waste is generated because it is used as soil material during repair and reconstruction. Has the advantage of being reduced to nature.

      Various problems of concrete asphalt roads have been reported in many studies and cases, and there have been studies to replace them with earth or agitated soil, which are environmentally friendly materials. Representatively, 'environmentally friendly granite block road structure' of Korean Utility Model Publication No. 364569, 'Road paving method using wet mixed stirring soil' of Korean Patent No. 392706, and 'Road construction of Korean Patent No. 901004 Composition '.

      On the other hand, there is a demand for various road pavement materials, and improved technologies are known to obtain better mixing performance. Basically, the dry and wet stirring device is to stir the contents of the main body by arranging the main body, the rotatable rotating shaft, the twisted arm of the screw-like arrangement, and the tip on the main body to rotate the rotating shaft so that the arm and the tip rotate along. But the tip did not reach evenly mixed.
