The steel pipe tubular pile is composed of a steel pipe, a tongue and groove groove, and a groove and groove pin. The left end of the steel pipe diameter is vertically connected to the groove groove. The cross section of the groove groove is a square shape with one side open. Reinforced ribs are provided on the side of the steel pipe. On the right-end pipe wall of the diameter of the steel pipe, there is a tongue-and-groove pin vertically connected to the radius.
When the utility model is used in the cofferdam, the steel pipe tubular piles overlap with each other in an arc shape or a round shape. Can play the role of water, soil, sand and so on. The utility model has a novel design, simple structure, easy to use, easy to overlap, and good sealing. It includes non-circular cross-sectional contours, equal wall thickness, variable wall thickness, variable diameter and variable wall thickness along the length direction, symmetrical and asymmetrical cross sections. Such as square, rectangular, tapered, trapezoidal, spiral tube, etc.
Special-shaped steel pipe tubular piles are more suitable for the particularity of the use conditions, saving metals and improving the labor productivity of parts manufacturing. It is widely used in aviation, automobile, shipbuilding, mining machinery, agricultural machinery, construction, textile and boiler manufacturing. The methods for producing special-shaped pipes include cold drawing, electric welding, extrusion, hot rolling, etc. Among them, the cold drawing method is widely used.
Steel pipe tubular pile is a foundation suitable for the construction of docks and ports, and its diameter range is generally between 400-2000mm, and the most commonly used is 1800mm. url:http://www.chinasteelengineering.com |
