TREATING METHOD FOR WATER, SEDIMENT AND MUD DISCHARGED IN CUTTING PROCESS FOR PAVEMENT SURFACE, TREATING APPARATUS THEREFOR, CUTTING WATER RECYCLING METHOD AND SEDIMENTATION TANK WITH SEDIMENT AND MUD TREATING FILTER

摘要

PROBLEM TO BE SOLVED: To solve the problem of the prior art that it takes long time as much as three hours or more to cause general precipitation of cutting chips such as sediment contained in water containing cutting chips such as sediment or the like, to supply a suitable quantity of quick setting cement to accelerate settling velocity, and to provide a sedimentation tank for separating water containing cutting chips such as sediment from the cutting chips such as sediment to deposit cutting chips such as sediment in the sedimentation tank. SOLUTION: This apparatus is formed of a cutting machine for a pavement surface, a water supply device, a drainage device and a sedimentation tank. The sedimentation tank is provided with a device for separating sediment and mud from muddy water. A method of the invention is a method for treating water, sediment and mud discharged in a cutting work process for the pavement surface. This treating method for water, sediment and mud discharged from the cutting process for the pavement surface is characterized in that in the process of cutting the pavement surface by a circular saw, water is supplied, water discharged with sediment and mud and sediment and mud discharged with the water are introduced into the sedimentation tank, the sediment and mud is filtered by a sediment and mud treating filter, and the water passed through the filter is reused as recycled water.
