Embodiment Construction

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0021] Such as Figure 1 to Figure 4 As shown, a hollow ground anchor cage foundation includes a foundation body 1 cast from concrete, a ground anchor cage 2 embedded in the concrete and a cushion 3, and the cushion 3 is arranged on the foundation body 1 and the bottom of the ground anchor cage 2; the ground anchor cage 2 is provided with a hollow cavity for placing support fillers, and the hollow cavity is located above the cushion layer 3; when the concrete is poured into the foundation body 1, the The support filler is embedded in the concrete, and when the anchor bolts of the ground anchor cage 2 are replaced, the hollow cavity that is convenient for people or tools to enter is formed after the support filler in...

Abstract

The invention relates to a hollow ground anchor cage base. The base comprises a base main body poured with concrete, a ground anchor cage and a cushion layer both embedded in the concrete, wherein the cushion layer is arranged below the base main body and the ground anchor cage; a hollow chamber used for placing a supporting filler is formed in the ground anchor cage; the hollow chamber is positioned above the cushion layer; when concrete is used for pouring the base main body, the supporting filler is embedded in the concrete; when the anchor bolts of the ground anchor cage are changed, the supporting filler in the concrete is dismantled, and the hollow chamber convenient for people or tools to enter is formed. According to the invention, the hollow ground anchor cage base is convenient to implement and low in cost; when the anchor bolts of the ground anchor cage need replacement due to fracture, rusting or the arrival of fatigue life, the concrete at the surface layer of the base main body center can be chiseled out, and hollow bricks inside are taken out, so that space for changing anchor bolts is formed, and the influence on the strength and whole stress of the base main body is avoided.

Description

technical field [0001] The invention relates to the technical field of foundation structures of wind power generation towers, in particular to a hollow ground anchor cage foundation. Background technique [0002] When the foundation ring is buried in the reinforced concrete foundation to connect the wind power generation tower and the foundation, the foundation ring isolates the inner and outer reinforced concrete, the combination of the two is weak, and the integrity of the force is poor. The ground anchor cage is used to connect the tower and the foundation. The foundation steel bars can be easily interspersed between the anchor bolts. The integrity of the combination of the anchor bolts and the foundation is good and the rigidity is uniform. The prestressing of the anchor bolts can improve the fatigue resistance of the concrete in the connection area. . [0003] In the current ground anchor foundation, if the ground anchor breaks or is severely corroded, the anchor bolt ...
