Abstract

The utility model discloses an indoor open trench of a basement, and is characterized in that a fine aggregate concrete cushion layer is 80-100 mm in thickness; a polyurethane waterproof layer which is 30-50 mm in thickness is arranged on the fine aggregate concrete cushion layer; a basement baseboard is arranged on the polyurethane waterproof layer; the strength of concrete adopted by the basement baseboard is C 30 and the anti-permeability level of concrete adopted by the basement baseboard is P 6; a concrete slope-making layer is arranged on the basement baseplate; the gradient of the top surface of the concrete slope-making layer is 2 %; the concrete slope-making layer breaks at the position 250 mm away from the side wall of the basement and forms an open trench with the side wall of the basement; the open trench is 250 mm in width and 150 mm in depth; and a cement mortar screeding layer is arranged on the concrete slope-making layer. The indoor open trench of the basement is simple and practical.
