Grease Inspection Box Detail 60x60 cm Concrete Chamber Section

This drawing presents a grease inspection box detail with a 60x60 cm chamber prepared in AutoCAD files for drainage and wastewater system construction. The plan view shows the inspection chamber layout with internal pipe alignment and structural wall thickness. The grease box chamber measures 0.60 m by 0.60 m internally and is constructed using concrete or fired brick masonry walls. The drawing illustrates inlet and outlet sanitary pipe connections of 100 mm diameter that allow wastewater to flow through the grease trap chamber. Structural dimensions, including the chamber base width of 0.90 m and side wall thickness of 0.15 m, are clearly shown to guide accurate chamber construction.
