TEMPORARY TRAPPING UNIT

PROBLEM TO BE SOLVED: To provide a temporary trapping unit which can temporarily be installed in a construction worksite unequipped with full drainage facility to achieve drainage treatment of any discharged water containing impurities without spending time and effort. SOLUTION: This temporary trapping unit comprises a trapping container, and a pan mounted on an opening over top of the trapping container. It is characterized by the fact that the pan has a vent for allowing drainage to flow into the trapping container, while the trapping container externally-discharges the drainage flowed into it from the pan after trapping impurities contained in the drainage.
