the first step is as follows: transverse bundling steel bars (42) and longitudinal bundling steel bars (43) in a prefabricated ground beam layer (4), prefabricating a reinforcing pile part (2) with a reinforcing groove (23), wherein the reinforcing groove (23) is matched with the longitudinal bundling steel bars (43), and prefabricating a foundation damping pipe network formed by vertically staggering transverse damping pipes (141) and longitudinal damping pipes (142) on a primary damping layer (3) and a secondary damping layer (9);
the second step is that: excavating a foundation layer (1), excavating to form a foundation pit, leveling the bottom of the foundation pit to form a leveling layer (7), burying the lower end of a prefabricated reinforcing pile piece (2) into the leveling layer (7), paving a layer of primary waterproof layer (6) on the top of the leveling layer (7), paving a prefabricated foundation damping pipe network on the primary waterproof layer (6), inversely inserting U-shaped reinforcing steel bars (15) at the staggered position of a transverse damping pipe (141) and a longitudinal damping pipe (142), and inserting reinforcing rods (16) into the leveling layer (7) through the primary waterproof layer (6) to form a primary damping layer (3) of the foundation;
the third step: fixedly paving pipelines on the top of the primary damping layer (3) to form a pipeline paving layer (13) of a foundation, backfilling excavated soil, paving a plain soil layer (5) on the top, and compacting the plain soil layer (5);
the fourth step: laying prefabricated transverse binding steel bars (42) and longitudinal binding steel bars (43) on a compacted plain soil layer (5), inserting the bottoms of the longitudinal binding steel bars (43) into a reinforcing groove (23) at the upper end of a reinforcing pile member (2), pouring concrete on the transverse binding steel bars (42) and the longitudinal binding steel bars (43) to form a beam layer (4) with a # -shaped structure, and backfilling the beam layer (4) to level the beam layer;
the fifth step: after the ground beam layer (4) is solidified, a geogrid layer (8) is laid on the top of the ground beam layer, a prefabricated foundation damping pipe network is laid on the geogrid layer (8), U-shaped reinforcing steel bars (15) are inversely inserted into the staggered positions of the transverse damping pipes (141) and the longitudinal damping pipes (142), and reinforcing rods (16) penetrate through a backfill layer (44) on the ground beam layer (4) to form a secondary damping layer (9) of the foundation;
and a sixth step: and a reinforcing layer (10) and a secondary waterproof layer (11) are sequentially paved on the top of the secondary damping layer (9), a steel bar woven mesh is paved on the top of the secondary waterproof layer (11), and concrete is poured on the top of the secondary waterproof layer (11) to form a concrete layer (12) of the foundation.
