More Information
Summary:In the present invention are disclosed a hollow steel pile (1) having an open extremity end with a helical projection (2,3) composed of a round rod or rectangular rod of its height less than 20 mm arranged at an outer circumference of the pile or at both outer circumference of the pile and inner circumference of the pile at a length part less than ten times of diameter of the pile, a method for fixing the inner circumferential projection and a pile execution method using such a pile as above. This hollow steel pile may preferably be used as a friction pile and a supporting pile, no vibration and noise are found during its execution of work, a better workability is assured, a cost of execution of work is less expensive and this process is suitable for performing in a narrow site.
