FIELD: construction, particularly to erect cast-in-place piles during building erection in immediate proximity to existent buildings and building structures, particularly to form all-purpose foundations, including ones to be built in soft soil.
SUBSTANCE: cast-in-place pile erection method involves drilling hole in ground with the use of drilling tool; concreting the hole and creating ground-and-cement case by simultaneous drilling and cementing operations in direction transversal to drilling axis. Cementing is carried out with the use of distribution member provided with nozzles having (2-5)·10-3 m diameters. Hole cementing rate is determined from a given relation. Hole concretion is executed as drilling tool is moved in reverse direction. Distribution member nozzles have diameters of (10-20) 10-3 m and provide concreting rate determined from a given relation. The drilling tool is provided with auger.
EFFECT: possibility of foundation building in soft ground, decreased foundation erection time along with strength and load-bearing property retention.
