The article discusses issues related to the construction of pile foundations of buildings and structures, including bridges and other transport facilities. The development of the construction industry contributes to the improvement of pile Foundation construction technology and a significant reduction in economic costs. Improving the design and technology of pile foundations is one of the main tasks in the field of transport construction. The effectiveness of pile foundations is due to the more complete use of the bearing capacity of the soil base and the strength of the Foundation elements. One of the disadvantages of the pile foundation is the low bearing capacity of the soil on the side surface of the pile. The proposed solution is based on the device along the longitudinal axis of the pile rigidly fixed, multi-pass continuous inclined edges having the shape of a plate, and faces adjacent to the side surface of the tubular steel barrel.

Studies of the piles bearing capacity after strengthening soil by cement mortar pressure injection were carried out to determine pile foundations bearing capacity increasing patterns in a result of soils cementation. Depending from the volume and cement mortar technological injection parameters, the soil stress state around the pile changes, additional pile-soil compression occurs and the friction along the lateral surface increase, as well as the soil resistance under the pile bottom end. Cementation effect on the pile bearing capacity for different injectors location and the number of piles in the foundation were determined by tests. The research results can be used in the pile foundations reinforcement design in conditions of reconstruction with increasing loads on the foundations.
