Description

TECHNICAL FIELD

[0001] This patent of invention application relates to a device to be used in mechanically enlarge of caisson bases, so that form a semi-spherical cavity at the base of caisson performed.

[0002] Currently, every soil excavating process for carrying out of base for caissons é performed manually, consisting of carrying out the same with a operator going down in the shank of caisson for enlarging the base, which process impose risks to the executor, incurring the possibility of soil landslip.

[0003] In this patent of invention application, the developed process has the purpose to remove the human figure of the process, avoiding burial risks and speeding up the base enlarging process, which is efficient in terms of reduction of execution time in the order of 80% or more.

[0004] Some features of purpose of invention are:

[0005] possibility of change in knives, which allows a opening of bases with different diameters;

[0006] creation of a collector system facilitating the removal of e...
