The invention discloses a hollow hole-digging foundation with a major diameter. The hollow hole-digging foundation with the major diameter comprises a basic main post and a basic wide bottom; the basic main post comprises a basic outcrop and a basic burial depth section, and the basic burial depth section is internally provided with a main post cavity; the basic wide bottom comprises a round table and a bottom cylinder, and the round table is internally provided with a bottom cavity; the main post cavity and the bottom cavity are filled with spoil; main post main reinforcements are connected with cylinder main reinforcements through round table main reinforcements, external stirrups are arranged on the outer sides of the main post main reinforcements, the round table main reinforcements and the cylinder main reinforcements, and erection stirrups are arranged on the inner sides of the main post main reinforcements, the round table main reinforcements and the cylinder main reinforcements. The invention further discloses a manufacture method of the hollow hole-digging foundation with the major diameter. The method comprises the following steps that 1, hole-digging foundation size parameters are initially set; 2, bending moment, shearing force, displacement and corner of the hole-digging foundation are calculated; 3, section size is checked; 4, normal section bearing capacity is calculated; 5, site construction is conducted. According to the hollow hole-digging foundation with the major diameter and the manufacture method thereof, use of foundation concrete and amount of the spoil are effectively reduced, the environment is protected, and the hollow hole-digging foundation with the major diameter can be widely applied to the technical field of electric power engineering.
