The surface of the railroad gravel is present with foreign matter (stone, earth) on it.

In this case, when the gravel is excavated and reused, the function of the surface is significantly lowered, and after the excavation, the gravel is reused through the sieve. At this time, the foreign matter on the surface lowers the function of the surface, The foreign matter of the product should be cleaned.

Also, re-excavated gravel is used as aggregate of concrete, and surface cleaning is also required to improve adhesion with cement.

For this purpose, a cleaning device for recycling the on-road gravel has not been available, and the cleaning has been carried out in a large water washing plant installed in the construction base, in order to secure the performance of the brine used mainly in the fresh construction.

The cleaning method applied to this method has a very large amount of water used as a natural descent method using hydrostatic pressure, and a device for treating contaminated water is not separately attached.

Especially, when the construction is completed, the plant is also dismantled, which makes it economically burdensome to use during the construction period of the short term.

In addition, when the gravel is washed through the plant-type washing and treating apparatus and the contaminated water containing foreign substances such as stones is discharged to the river, serious water pollution occurs and collective death occurs due to the contaminated water There has been a problem that it seriously affects environmental pollution.

In addition, in the process of cleaning the gravel through the plant type water washing treatment apparatus, when the chemicals are mixed with the washing water to remove the foreign substances on the surface of the gravel, it is necessary to increase the acidity of the water quality, There has been a problem that water pollution is accelerated by causing eutrophication.
