FIELD: construction.
SUBSTANCE: shell pipe is made of hollow metal or reinforced concrete cylinders joined by means of electric welding or bolt joints. In order to increase bearing capacity and improve process capabilities, there is a diaphragm installed into inner cavity of pile, providing for formation of compacted zone of soil under spike, controlling depth of its submersion and specified bearing capacity. Diaphragm is made in the form of truncated cone oriented towards pile head and with hole in its upper part.
EFFECT: increased bearing capacity, reduction in material consumption and labour costs.
