Current procedures and problems in underground construction were evaluated in the areas, of cut and cover methods, deep shafts, tunneling, ground water control, security and survivability, costs, and energy savings. 1.2 OBJECTIVE The test mandrel is sized to be smaller than the inside diameter of the duct so that some deflection of the ducts is allowable. These facilities are often quite old, and the set of requirements on which they were designed and built differ from those considered important today. Accordingly, it is necessary to check for duct deflection before any cable installation. You can list yourself here by submitting civil engineering related topics to us.
