The invention relates to a spiral pile capable of adjusting an eccentrically-installed vertical post, which is suitable to be used as a support system of a ground photovoltaic support in various geological environments. The spiral pile comprises a spiral pile anchor bolt (1), a big rubber gasket (2), a small rubber gasket (3) and a steel ring (4), wherein the top end of the spiral pile anchor bolt (1) is provided with a round tray; the big rubber gasket (2) and the small rubber gasket (3) are open eccentric round rings; the steel ring (4) is an open round ring; the big rubber gasket is arranged in the tray at the top end of the spiral pile anchor bolt; the small rubber gasket is arranged in the big rubber gasket; the steel ring is sleeved at the periphery of the big rubber gasket; and thesteel ring and the spiral pile anchor bolt are in locking connection by a bolt. The problem of the eccentrically-installed vertical post can be solved by matching the big rubber gasket with the smallrubber gasket, the assembly effect of the spiral pile is improved, and the stress and the stress concentration of the spiral pile under the action of large force can be reduced, so the spiral pile has a better safety function.
Description
technical field [0001] The invention relates to an eccentric adjustable spiral ground pile installed on a column, which is used for ground fixing and supporting of a solar energy system. Background technique [0002] With the increasingly tense energy supply and the deteriorating environment, the application field of solar photovoltaic power generation as a new type of energy is expanding day by day. As the supporting structure of the photovoltaic power generation system, the photovoltaic support system is an important part of the photovoltaic power generation system. Most of the solar photovoltaic supports are arranged continuously in a large area. Therefore, in addition to having sufficient strength and rigidity, the solar photovoltaic supports also need to have good installability. As a key component connecting the solar photovoltaic support system to the ground, the spiral ground pile plays a very important role in ensuring the stability and safety of the overall system...
