As the necessary fluidness of a mass of gravel, pebbles, or solid clay cannot be attained by the application of a water-jet under ordinary pressure, it is in sandy soil having fine particles easily transported under slight pressure, or in loamy soils which on water being forced into them quickly become liquid mud, that the water-jet system is particularly successful. The nozzles of the discharging jet should be properly formed in accordance with the most approved shape, and it is important that the pumps have ample power and capacity to fully and continuously feed the jets. CHAPTER XVIII. The Well System Of Foundations For Bridge-piers, Abutments, Quays, And Dock-walls, Etc. The well system is particularly adapted for loose sand, mud, and silt, but practice shows it is not suitable for soil harder than ordinary sand, unless under exceptional circumstances. It is an especially good method, if the mud is sufficiently watertight, for the well to be pumped dry, so that the excavation can be executed without dredging machinery. It has many important advantages over a timber pile foundation in sand, silt, or mud, and in warm climates should be preferred. Brick walls have been sunk through clay, boulder sand, and solid beds of shingle. If boulders or debris are expected to be encountered in sinking, masonry, concrete, or brick cylinders should...
