For egg shapea sewers use same size of expanded metal and thickness of concrete, the 

 diameter given in the table being the horizontal diameter. 



Under ordinary conditions these sewers may be used for any depth of fill and when required 

 to sustain a heavy live load, such as a road roller, the depth of fill should be not less than 3'0" for 

 the given size of reinforcement. When severe conditions of loading and bedding are encountered 

 it is preferable to use two layers of expanded metal, one near the inside and one near the outside. 

 A double reinforcement will generally provide for all contingencies. When using two layers of 

 " Steelcrete " reinforcement select the next size of mesh lighter than that shown in the table. 

 It is important to note that in placing ' ' Steelcrete " reinforcement in sewers and conduits 

 the long way of the diamond should lie in the direction of the circumference and the short way of 

 the diamond in the direction of the axis of the pipe. This will give the strongest method 

 of reinforcement. *
