Drainage Section Detail With 40cm Channel And 60cm Depth Layout

This drainage section detail drawing shows the internal construction layout of a drainage channel system with clearly defined structural layers and dimensional references. The section illustrates a drainage channel with a minimum internal width of 40 cm designed for water flow through a concrete pipe outlet positioned at the base of the channel. The overall drainage pit depth is approximately 60 cm, with an additional structural base thickness of about 7 cm supporting the system. The drawing also presents the finished floor layer with concrete topping marked F C 150kg per cm and a cement mortar finish prepared with an arena proportion of 1 to 5. Reinforced concrete beam support and block wall cement construction are illustrated on both sides of the drainage channel to stabilize the structure and guide water flow toward the outlet pipe.
