For almost all tower barrel reinforcement devices in the prior art, after retrieval, the utility model patent with the Chinese patent publication number CN217231916U discloses a land-based wind turbine tower barrel root foundation reinforcement device. As Figure 1 shown, it mainly includes a ring anchor a. There is a reinforcing rib plate b on the outside of the ring anchor a, a radial steel bar c is arranged on the outside of the ring anchor a, a vertical steel bar d is arranged on the outside of the radial steel bar c. The ring anchor a is arranged above the original foundation e and surrounds the outside of the tower barrel f. The vertical steel bar d is arranged on the outside of the original foundation, and then the pouring g of the foundation reinforcement part is carried out.

[0003] In the prior art, for a tower barrel foundation reinforcement device similar to the above technical solution, it is found that there are areas for improvement during actual implementation: directly pouring concrete outside the vertical steel bars. Since there is no external formwork, it is inconvenient to control the pouring shape. In addition, since there is no external formwork, when pouring, the concrete is prone to flow outward, resulting in the inside of the poured concrete not being solid enough, and the fastening effect of the pouring needs to be improved. Content of the Utility Model

[0004] In view of the deficiencies and defects existing in the prior art, the purpose of the utility model is to provide a tower barrel foundation reinforcement device, which solves the problems that the existing tower barrel foundation reinforcement device is inconvenient to control the pouring shape, and when pouring, the concrete is prone to flow outward, resulting in the inside of the poured concrete not being solid enough, and the fastening effect of the pouring needs to be improved.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme: A tower barrel foundation reinforcement device is arranged outside the original foundation, including an annular ring anchor plate. The ring anchor plate includes two semi-circular component plates. The ring anchor plate is sleeved outside the tower barrel and placed above the original foundation. The ring anchor plate is bolted to the original foundation, and there are a plurality of through-pouring holes on the ring anchor plate. Concrete is poured into the through-pouring holes. There is a gap between the ring anchor plate and the tower barrel, and concrete is poured into the gap. There is a wrapping member around the vertical surface of the original foundation. The wrapping member includes at least two detachably connected reinforcement sheets. There is an external formwork on the outside of the wrapping member. There are a plurality of rib plates between the external formwork and the wrapping member, and concrete is poured between the external formwork and the wrapping member.

[0006] As a further improvement of the present utility model, the outer mold includes two component templates. On one side where the two component templates are connected, two docking plates are fixed respectively, and the two pairs of docking plates are connected by bolts.

[0007] As a further improvement of the present utility model, both ends of the reinforcing piece are provided with connecting plates, and the butt - joint connecting plates are connected by bolts.

[0008] As a further improvement of the present utility model, an anti - corrosion layer is painted on the upper side surface of the ring anchor plate.

[0009] As a further improvement of the present utility model, an anti - corrosion layer is painted on the outer side surface of the outer mold.

[0010] Compared with the prior art, the present utility model has the following advantages:

[0011] 1. By providing a ring anchor plate, and the ring anchor plate is composed of two component plates, the two component plates can be naturally clamped on the outer side of the tower barrel. In addition, there is a gap between the ring anchor plate and the tower barrel, and concrete is poured into the gap. Therefore, the ring anchor plate and the tower barrel are directly and firmly connected through the concrete. In addition, the ring anchor plate is connected to the original foundation by bolts, and there are multiple through - pouring holes on the ring anchor plate, and concrete is poured into the through - pouring holes. Then the ring anchor plate is directly and firmly connected to the original foundation through the concrete, so that the ring anchor plate, the tower barrel, and the original foundation form a connected whole, and the connection tightness is very strong.

[0012] In addition, by providing a wrapping piece on the outer side of the vertical surface of the original foundation, and an outer mold is provided on the outer side of the wrapping piece, and concrete is poured between the outer mold and the wrapping piece, the original foundation can be integrally wrapped and reinforced from the periphery of the original foundation, preventing the original foundation from cracking or collapsing, and greatly improving the reinforcement effect on the original foundation. The setting of the outer mold facilitates the formation of a gap with the wrapping piece for pouring concrete. The outer mold is convenient for the external shaping of the concrete, and the extrusion between the outer mold and the wrapping piece makes the poured concrete between the two compacted, thereby improving the overall reinforcement effect.

[0013] 2. By painting an anti - corrosion layer on the upper side surface of the ring anchor plate and an anti - corrosion layer on the outer side surface of the outer mold, corrosion can be prevented and the overall service life can be improved. BRIEF DESCRIPTION OF THE DRAWINGS
