Specific features of sewer tunnel construction and rehabilitation in Saint-Petersburg
Summary
The basic facts about the construction of deep sewer tunnels in Saint-Petersburg are presented. The causes of gas corrosion in sewers and their structural components are considered. The methods of protecting sewer tunnels in the process of construction or rehabilitation from gas corrosion are suggested. At the stage of designing the construction of a new sewer or its rehabilitation the concentration of gases in the underroof space must be measured. On the basis of the calculation data the decision on the sewer design, elevation differences, gradient and other parameters that ensure trouble-free operation is made.
