发明名称 Sanitary, storm and catch basin trap with filter insert
摘要 A temporary trap having baskets and optionally filters in the baskets used in conjunction with inlets for sewer systems to keep debris, oils or chemicals from being washed into the sewer during construction of roads and sewers. The trap is a box, typically rectangular, square or round, with baskets having a plurality of holes therein for allowing water to pass therethrough while trapping debris therein. The trap is inserted into a inlet by lifting the grate off the inlet frame, inserting the trap and then replacing the grating. After a rain the baskets and filters may be cleaned out and reused or replaced. When the construction project is finished the grate is lifted off the inlet frame and the trap removed. The trap has an overflow opening in case the trap becomes clogged.
