Example 1

Referring to fig. 1-2, a novel energy-saving and environment-friendly stiffening core composite pile comprises an outer core 1 and an inner core 2 inserted into the outer core 1, wherein the outer core 1 is formed by pouring in a pile hole, the inner core 2 is prefabricated, when the composite pile is assembled, after the on-site punching and pouring are finished, the prefabricated inner core 2 is inserted into a pouring object in the pile hole, after the pouring object is solidified, the composite pile is formed, wherein the pouring object which is wrapped outside the inner core 2 and is solidified and formed is the outer core 1, the pouring object which forms the outer core 1 is mainly formed by cement and separated slag fly ash, the utilization of resources such as natural pebbles, broken stones and river sand is reduced, the environment-friendly effect is achieved, steel slag can be doped in the pouring object to improve the structural strength of the outer core 1, and the composition of the inner core 2 can comprise construction wastes such as coarse aggregates, concrete blocks and the like, and the composite pile belongs to secondary utilization, energy conservation and environment protection and cost saving.

In order to facilitate positioning of the inner core 2 inserted into the outer core 1, a pile cone 202 may be disposed at the bottom end of the inner core 2, the pile cone 202 is pointed downward, after the inner core 2 is inserted into place, the pile cone 202 is inserted into soil to realize preliminary positioning of the inner core 2, the outer core 1 and the inner core 2 are concentrically disposed, outer ribs 201 are disposed on the side wall of the inner core 2, the outer ribs 201 protrude outwards along the radial direction of the inner core 2, two groups of outer ribs 201 are disposed on opposite sides of the two groups of outer ribs 201, the two groups of outer ribs 201 are parallel to each other, each outer rib 201 extends along the axial direction of the inner core 2, the outer ribs 201 of each group are distributed in an annular array, the outer ribs 201 of each group are uniformly distributed at equal intervals, the outer ribs 201 of the shape can enable the outer core 1 to form an 'inner rib' (i.e. the part of the outer core 1 between the two outer ribs 201 of the groups), that is, the two outer ribs 201 of the groups form a mould for forming an 'inner rib', thus, the outer ribs 201 and the 'inner rib' are disposed in a cross manner, the inner rib 'is mutually and the inner rib's 2 is increased, the contact area of the inner core 1 is greatly increased, and the strength of the inner core 1 is greatly increased, and the outer core 1 is connected with the inner core 2.
