Because of the dense population of megalopolises the main share of construction is the share of construction of multystoried buildings at which the pile base acts as the load-bearing frame perceiving loading from the building and transferring her to the basis. Therefore the knowledge of a production cycle of immersion of a pile and nature of change of parameters of equipment for pile works that will allow to increase an efficiency of installation of the bases is very important. For this purpose in article dependence of efficiency of blow of a hammer on depth of immersion of a driven pile in a clay soil is studied.As the equipment for pile works the rod and tubular diesel hammers immersing a pile in a clay soil of various fluidity are chosen ( , , ), Schedules of change of the settlement resistance of a soil under the lower end of a pile and settlement resistance of the i-th layer of soil on the side of the base of the pile are calculated and represented. Besides, the bearing ability of a pile is determined by a soil. Distinctions between rod and tubular diesel hammers, namely, different values of efficiency of diesel hammers are designated. Considering these distinctions, calculation of change of efficiency of blow of a hammer for three indicators of fluidity of a clay soil is made. The revealed dependences allowed to draw conclusions on nature of change of settlement resistance of a soil, efficiency of blow of diesel hammers. Probe has dot character and can be used for deeper studying of change of efficiency of blow of pile hammers.
