Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of construction support, in particular to a wind farm construction support pile and high slope retaining wall reinforcing structure. BACKGROUND

[0002] Wind power is renewable, pollution-free, energy, and has a broad prospect. More and more large-scale wind farms are being built. Wind power, as the name implies, needs strong wind to blow the fan blades to generate electricity. Therefore, when building a wind farm, it is necessary to use an ultra-high support to support the fan blades to a high altitude to ensure sufficient wind power.

[0003] During the construction of a wind farm, the base support of the wind power is particularly important, and a super-stable foundation needs to be built. During the construction of the foundation, large-scale excavation is certainly required. In order to avoid the collapse of the foundation hole, support and reinforcement are needed.

[0004] The current reinforcement method generally drills a deep inclined hole in the slope, inserts an anchor rod after cleaning the hole, and then grouts to connect the support rod on the surface of the slope for reinforcement. In order to ensure the reinforcement effect, the anchor rod needs to be located in the middle position of the inclined hole after drilling, which generally needs to be supported. The existing support directly uses a support with a diameter similar to that of the inclined hole. Due to the similar diameters, on the one hand, it is not convenient to insert the anchor rod deeply into the inclined hole, and on the other hand, it will collide with the internal soil of the inclined hole and fall into the inclined hole, which will adversely affect the subsequent grouting and solidification.
