They were jetted down, no driving beingdone. The Chenoweth pile is reinforced with rods and wire mesh, therods are wired to the mesh, the concrete is then spread flat onthe mesh, and all are rolled together on a machine built forthe purpose. Piles up to 61 ft. in length can be made on thismachine. They are driven with a regular pile driving machine, 478 HANDBOOK OP CONSTRUCTION PLANT preferably, as is the case with all concrete piles, with a machinehaving a steam hammer. Mr. Gillette gives the cost of this pileas $ per lin. ft. in place. Another rolled pile is the Ripley Combination pile, in whichconcrete roinforced with wire mesh is rolled around a wooden. Fig. 213.

The concrete in this case is useful to strengthen the pileand, particularly, to protect it from the action of the teredo ormarine borer, for in docks having a concrete superstructureof girders and beama, the joint of the girder and wood and con-crete pile would be a difficulty, tending rather to the making of aweak joint at a critical point of the structure.
