A pile-breaking module for assembling concrete pile-breaking equipment relates to pile-breaking equipment. At present, the conventional pile-breaking equipment is integrated and is inflexible for use, great in investment and difficult for arrangement. The pile-breaking module is characterized by comprising a fixed body, an impact oil cylinder, cylindrical drill rods and a hanging ring, wherein the impact oil cylinder is arranged on the fixed body; the cylindrical drill rods are connected with the impact oil cylinder; the handing ring is arranged on the top surface of the fixed body and used for allowing the hanging ring to penetrate through; the heads of the drill rods are conical; a first connection end and a second connection end are arranged on the left side and the right side of the fixed body respectively; the pile breaking module is detachably connected with a second connection end of another pile breaking module through the first connection end of the fixed body; and a plurality of pile-breaking modules are connected end to end, so that the annular concrete pile-breaking equipment with radially distributed drill rods is formed. According to the technical scheme, pile-breaking equipment with different inner diameters are formed through splicing, so that piles with different diameters are adapted, pile-breaking is more efficient, the equipment is low in cost and convenient and flexible for use, and the occupied space is small after disassembly of the equipment.
