  1. II. Sewer Networks and FacilitiesTopic II.3. Sewer Pipes: Kinds, Joints, Foundation.Sewer Network Design Sewer Pipes Profiles: • Normal (b/h  1) • Circular • Trapezoidal • Square • High (b/h < 1) • Egg-shaped • Ellipsoidal • Oval • Horseshoe • Low (b/h > 1) • Mouth-shaped • Rectangular • Combined

  2. Sewer Pipes Profiles: a - circular б - egg-shaped (inverted) b - egg-shaped г - mouth-shaped д - square e - trapezoidal Sewer Pipes

  3. Sewer Pipes Materials: Concrete, Reinforced concrete, Prestressed concrete Ceramics Asbestos cement Cast iron Steel Plastics - PVC, PE, PP, reinforced with fibre-glass Resins - epoxy resin, reinforced with fibre-glass Sewer Pipes
