Introduction

The purpose of the course project is to design cold water supply and sewerage systems for the attached building.

Course work is performed on an individual assignment.

The work consists of a graphic part (A1 sheet) and a calculation explanatory note (1015 sheets of text).

The graphic part contains 6 drawings: plot plan (M 1:500), plan of the 1st floor (M 1:100), basement plan (M 1:100), axonometric diagram of cold water supply (M 1:200), axonometric diagram of internal drainage (M 1:200) and longitudinal profile of the yard drainage network (Mvert 1:200, Mg.

The calculation and explanatory note includes sections: "Design of the cold water supply system of the building," "Design of the indoor and yard water disposal system." The note contains data on hydraulic calculation of water supply and drainage networks in the form of tables, as well as text material and figures explaining and justifying the adoption of technical decisions.

Design of in-house and yard sewage system

3.1. Solution of the object drainage scheme.

General Plan (M 1:500).

The plot plan shows the gravity drainage network, which includes sewage outlets from the building, a yard network of ceramic pipes with a diameter of 150 mm, inspection wells KK11, KK1-2, KK13 and KK14, a rotary well KP, control KK2 and a city sewage well KGK. Yard drainage network with wells installed on it shall be laid at a distance of at least 3 m from the building foundation and other parallel communications. The control well is installed 2 m from the red building line on the side of the courtyard.

Ground floor plan.

The first floor plan shows projections of 100 mm diameter drainage risers with their numbering (St K11, St K12, etc.) and discharge pipelines (50 mm diameter).

The basement plan shows projections of drainage risers, exhaust pipelines with brushes near the external walls of the building. The outlet diameter is assumed to be equal to the riser diameter (100 mm) if the outlet serves one riser. With two or more risers, the diameter of the outlet is taken to be 150 mm.
