Abstract

The invention discloses a concave-convex friction pile. A concave-convex structure is arranged on the outer surface of a pile body of the friction pile in the length direction of the pile body. The concave-convex structure is transverse or longitudinal. The concave-convex friction pile has the advantages that the concave-convex structure is particularly suitable for water stop of a port, a pier and a deep foundation pit, the frictional resistance of the pile is greatly increased through the concave-convex structure, the bearing capacity of the pile is increased, and the anti-floating effect and the anti-seismic effect are good.

Description

technical field [0001] The invention relates to the field of building construction, and mainly refers to a concave-convex friction pile. Background technique [0002] With the rapid development of offshore engineering and port engineering, the existing prestressed concrete piles are difficult to meet the engineering needs due to their limited friction and low bearing capacity of single piles. Therefore, the construction cost is relatively high, a large amount of concrete and steel bars are required, and there are major problems in both economic and environmental benefits. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides the following technical solutions: [0004] A concave-convex friction pile, the external surface of the friction pile is provided with a concave-convex structure along the pile body and pile length; the concave-convex structure is horizontal or vertical. [0005] In the present invention, th...
