Squeezed branches and plates pile and DX squeezed pile are new types of pile developed from normal bored pile. Compared with normal bored pile, its ability to afford the load of individual vertically and unit consumption of concrete is apparently higher and its social and economical profit is obvious. First, It conducts a comparative study of two extruding devices (one-way extruding device and two-way extruding device), and concludes that the bearing capacity of branches and plates formed through two-way extruding device is much better than that of branches and plates formed through one-way extruding device. After analyzing the process of plates being formed through two kinds of equipments, a method is provided to draw the outline of two types of dishes respectively, and deduces the formula of dish volume which affords the load.
