In the construction of wind power equipment, the foundation structure is the top priority to ensure the overall quality of the project. The existing publication number is CN212561601U, which is a new and expanded wind power foundation on a shallow overburden layer of a weak foundation and a construction method thereof. The method is to set a ring pile group in the shallow overburden layer of a weak foundation, or in the shallow overburden layer of a weak foundation and around the original wind power foundation, set a ring beam on the ring pile group, set a foundation top plate inside the ring beam, or surround the wind power foundation. The original wind power foundation base inside the ring beam is reused, a platform column is set on the foundation top plate or foundation base, a reinforcing member for supporting the platform column and transferring the platform column load is set between the ring beam and the platform column, and a foundation ring for tower installation and fixation is fixed on the platform column to complete the new construction and expansion of wind power foundations, meeting the actual needs of new construction and expansion of wind farms on shallow cover layers of soft foundations. Its advantages are that the large bending moment load generated during the operation of the wind turbine is resisted by using the pressure of the extended foundation top cover and the active and passive earth pressure of the side wall barrel foundation, which makes full use of land resources, improves bearing capacity, reduces costs, and improves efficiency.

[0004] 2. The reinforcement method is too simple, there is a lack of auxiliary support structure between the tower body and the foundation, and the tower body lacks lateral tensile strength in strong wind weather;

[0005] There may already be technical means to solve the above problems in the prior art, but this case intends to provide an alternative or replacement technical solution. Utility Model Content

[0015] Beneficial Effects

[0016] The utility model provides a foundation structure with good stability for wind power civil engineering projects. Compared with the prior art, when the geological vibration occurs, the kinetic energy generated by the vibration will be transmitted upward from the base to the base, and the base will then transmit the force upward through the support column. At this time, the support column will deform and shrink, and the spring on the outer wall of the support column will reduce part of the vibration force, reduce the impact on the upper base, and thus protect the wind power building. In strong wind weather, the shaking of the tower body is very likely to affect the upper base. By arranging a tension spring and a telescopic rod, the upper base is auxiliary supported, and the shaking force transmitted by the base is converted into the workmanship of the tension spring to be consumed, so as to reduce the shaking and avoid the base being affected, thereby solving the problem of the prior art equipment:

[0017] 1. When encountering geological vibrations, it cannot effectively buffer the impact of vibrations on the tower body;

[0018] 2. The reinforcement method is too simple, there is a lack of auxiliary support structure between the tower body and the foundation, and the tower body lacks lateral tensile resistance in strong wind weather. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0024] Example: See Figure 1-3 ,The main components of this case are: base 1, a buffer structure is installed on the base 1, and an auxiliary support structure is installed on the base 1;

[0025] The buffer structure includes: a bottom tube 2, a base 3, a stabilizing plate 4, a support column 5, a spring 6 and an upper base 7;

[0026] The bottom tube 2 is installed at the center of the upper end of the base 1, the base 3 is installed at the inner center of the bottom tube 2, the stabilizing plate 4 is installed around the outer wall of the bottom tube 2, the support column 5 is installed at the upper end of the base 3, the spring 6 is wound around the outer wall of the support column 5, and the upper base 7 is installed at the upper end of the support column 5. Multiple support columns 5 are evenly distributed between the base 3 and the upper base 7, and the upper base 7 and the bottom tube 2 are clearance-matched.

[0027] It should be noted that when geological vibration occurs, the kinetic energy generated by the vibration will be transmitted upward from the base 1 to the base 3, and the base 3 will then transmit the force upward through the support column 5. At this time, the support column 5 will deform and shrink, and the spring 6 on the outer wall of the support column 5 will reduce part of the vibration force, reducing the impact on the upper base 7, thereby protecting the wind power building.

[0028] In the specific implementation process, further, the auxiliary support structure includes: a rotating seat 8, a sleeve 9, a telescopic cavity 10, a limiting column 11, a telescopic rod 12 and a tension spring 13;

[0029] The rotating seat 8 is respectively installed on both sides of the upper end of the base 1 and on both sides of the outer wall of the upper base 7, the sleeve 9 is installed on the upper end of the lower rotating seat 8, the telescopic cavity 10 is opened inside the sleeve 9, the limit column 11 is located at the center of the telescopic cavity 10, the telescopic rod 12 is installed on the upper end of the limit column 11, the upper end of the telescopic rod 12 is connected to the upper rotating seat 8, the two ends of the tension spring 13 are respectively installed on the lower end of the limit column 11 and the bottom end of the telescopic cavity 10, a sliding structure is formed between the sleeve 9 and the limit column 11, and the left and right sleeves 9 are symmetrical with each other along the vertical center of the base 1.

[0030] It should be noted that in strong wind weather, the shaking of the tower body can easily affect the upper base 7. By setting the tension spring 13 and the telescopic rod 12, the upper base 7 is auxiliary supported, and the shaking force transmitted by the upper base 7 is converted into the workmanship of the tension spring 13 for consumption, thereby reducing the shaking, avoiding the base 1 from being affected, and making the base more stable.
