Perforated pile embankment with a three-branch self-locking structure.

Abstract

The useful solution “Three-branch self-locking perforated pile dike” includes: perforated pile dike components with a three-branch cross-section in the form of a curved structure with radius R, in which these pile dike components can be divided into many different components (9) and connected through driven piles (6) with concrete infill (7) in the hollow part of the dike (1), the pile dike is designed in one layer, or multiple layers, the dike layers are also naturally and tightly connected to each other. The pile dike has 03 branches (2) with perforations (3), the perforations are outside the overlapping position between the pile dikes, the piles are connected to each other by interlocking (4) and (5), between the pile dikes are connected to each other by the arrangement of contact between the branches and the indentation of the pile body. The pile dike can use one line or multiple lines, the dike lines are also connected to each other by natural contact interlocking through the curved surface with the same radius R.When constructing the dikes, the pile grid (8) and the pile driving position (6) will be positioned. After the piles are driven, the pile dike components (9) will be assembled together. Each pile will be positioned and assembled, then the contact angle between the pile dike will be adjusted so that the outer surface of the branch (2) contacts the concave part in the center of the adjacent pile dike. Temporarily fix the pile dikes and then pour concrete to fix the pile dikes. The connection between the piles will be complete, and the more layers of pile dikes there are, the tighter the connection structure will be.
