Embodiment 1

[0036] Such as Figure 1-Figure 3 As shown, this embodiment provides a pile-type adjustable fan foundation of the present disclosure, including a fan foundation 1, a plurality of supporting structures arranged around the bottom of the fan foundation 1, and the supporting structure includes piles 7, caps 5 and columns 3, Pouring in the order of pile 7, cap 5, and column 3 to form a whole, and column 3 is in free contact with fan foundation 1;

[0037] The number of supporting structures is determined by checking the bearing capacity. In this embodiment, 8 supporting structures are used, which are symmetrically arranged around the bottom of the fan foundation 1 . The support structure is poured into a whole in the order of pile 7, cap 5, and column 3, which can bear the upper load transmitted from the base of the fan foundation 1. Due to the support structure, the probability of settlement and inclination of the fan foundation 1 is reduced.

[0038] The pile 7 is preferably a c...

Embodiment 2

[0052] This embodiment provides a construction method for a pile-type adjustable fan foundation according to Embodiment 1, which is characterized in that it includes the following steps:

[0053] Step 1, sequentially construct pile 7, cap 5, and column 3 to form an integral pouring support structure. The specific steps are to first set out the line on site during the construction process, locate the position of pile 7, use the post-grouting process for construction, and process the pile head; At the top of each pile 7, after the earthwork excavation elevation and flatness meet the requirements, build the formwork construction cap 5 to ensure that the top of the pile 7 enters the bottom of the cap 5 by at least 100mm, and the longitudinal main reinforcement at the top of the pile 7 is anchored into the length of the cap 5 It should not be less than 35 times the diameter of the longitudinally stressed main reinforcement. When the poured concrete reaches the design threshold, the ...

Abstract

The invention relates to a foundation, and particularly relates to a pile type adjustable fan foundation. The pile type adjustable fan foundation comprises a fan foundation body, a plurality of supporting structures, jacking devices and filling structures; the supporting structures are arranged on the periphery of the bottom of the fan foundation body; each supporting structure comprises a pile, a bearing platform and a column, wherein the pile, the bearing platform and the column are poured into a whole in sequence, and the column makes free contact with the fan foundation body; the jacking devices are arranged on the tops of the bearing platforms, the tops of the bearing platforms serve as datum planes, and the jacking height of the jacking devices is larger than the height of the columns; the tops of the filling structures make contact with the bottom of the fan foundation body, and the bottoms of the filling structures extend downwards to a soil layer with the set depth; and each filling structure comprises a slurry containing layer, and gaps formed after the fan foundation body is jacked are filled by injecting solidifiable slurry into the slurry containing layers. The supporting structures, the filling structures and the like are all completed before construction of the fan foundation body, deviation rectification or jacking can be achieved without later excavation, and an original fan foundation structure is prevented from being damaged.

Description

technical field [0001] The disclosure relates to a foundation, in particular to a pile-type adjustable fan foundation. Background technique [0002] The statements herein merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] In order to promote the development of wind energy industry, wind turbines are built in desert areas, mining subsidence areas and dumps to achieve the purpose of saving and intensive land use and promoting desertification land control. However, the key engineering problem involved in the construction of wind turbine projects in these areas is that the soil quality is poor, which leads to the risk of settlement or inclination of the wind turbine foundation built in the later stage. [0004] The solutions in the prior art are divided into pre-processing and post-processing. (1) The pre-processing usually uses foundation treatment to improve the strength of the foundation soil, or uses...
