Continuous duct is predominantly installed using ‘no dig’ methods which require the duct to be pulled through the ground. This requires a pulling load to be applied to the duct in order to draw it forward and the load requirement will be influenced by; the length and straightness of the run,
the friction between the pipe, and the surrounding ground and diameter of the pipe
Where possible, the minimum towing load to achieve the installation should be used and in no case should the loads in the following table be exceeded. Exceeding these loads may result in a reduction of the diameter and wall thickness of the duct.
When slip lining it is recommended that for long strings, a pipe relaxation period of at least 24 hours is allowed before grouting or making permanent tie-in joints.
Where a pipe of a greater wall thickness (lower SDR) is being used to those shown in the table then he same guidelines can safely be used.
