Abstract

It was considered necessary to produce simplified tables to provide pipeline designers with compatible documents for the loadings on buried rigid pipes. The present tables, intended principally for use with pipes of rigid materials, e.g. asbestos-cement, vitrified clay and concrete, are wholly metric and have been arranged to provide some degree of flexibility in the design assumptions. However, it must be stressed that these tables are 'simplified', the values being obtained by adopting global parameters throughout. The pipe loads given by the tables may be found to differ slightly from those given by previous tables being, for example, a little higher for large pipes at shallow depths. For convenience, the tables now give, in addition to the pipe loadings, the safe supporting strength of standard classes of pipe when laid on typical beddings, thereby affording a quick comparison between load and supporting strength, so as to facilitate the choice of a suitable pipe. A table has been added from which the effect of very heavy vehicles of the earth-moving type can be assessed, so that, where necessary, such loads may be taken into account in design. Although intended mainly for the design of rigid non-pressure pipes laid in trenches, the load tables can also be of use in determining the external loads on pressure pipes, or on individual pipes laid in a multi-pipe trench and in the design of pipes laid in an embankment.
