Self-elevating drilling platform pile leg
The invention discloses a self-elevating drilling platform pile leg which comprises a plurality of vertically overlapped pitch units. Each pitch unit is of a truss structure, three rectangular side faces enclose the truss structure, the outer edge of the cross section of the truss structure is an equilateral triangle, each pitch unit comprises three leg chord units, the three rectangular side faces sequentially include a first rectangular side face, a second rectangular side face and a third rectangular side face, and each rectangular side face comprises a main diagonal bar and an auxiliary diagonal bar which are positioned on diagonal lines of the rectangular side face respectively. The pitch unit positioned at the top end of the pile leg is a top end pitch unit, the pitch unit positioned at the bottom end of the pile leg is a bottom end pitch unit, and the top end pitch unit further comprises a horizontal stay bar and a vertical stay bar. Compared with the prior art, the pile leg with an X-shaped structure has the advantages that materials of the pile leg are saved on the premise of ensuring important technical indexes such as bearing capacity, and manufacturing cost is reduced.
