In some places, the weathered dolomitic limestone in the rock layer is buried shallowly or exposed, and the drilling difficulty is relatively large. At present, the foundation of mountain photovoltaic brackets usually adopts the "micro-hole cast-in-place pile" foundation, and the "micro-hole cast-in-place pile" foundation is suitable for mountain foundations where the buried depth of the rock layer is greater than 0.7 m.

[0003] In the patented document with the authorized publication number of CN216948411U, a rock foundation structure of a photovoltaic bracket is disclosed, which includes a tensioning rope, a casing with an axis extending in the vertical direction, and a pile body embedded in the rock. There are at least three pile bodies, and the pile bodies are arranged around the casing. The pile body is a cable anchor or an anchor bar. The top of the pile body exposes the top surface of the rock. One end of the tensioning rope is fixedly connected to the pile body, and the other end of the tensioning rope is connected to the casing; the casing is arranged on the rock or in the space of karst collapse; when the casing is arranged on the rock, the bottom surface of the casing contacts the top surface of the rock, and the tensioning rope is used to keep the axis of the casing in the vertical direction; when the casing is in the space of karst collapse, the tensioning rope is used to keep the axis of the casing in the vertical direction, and the tensioning rope is used to bear the force applied by the casing. In addition to being applicable to rock foundations, it is also applicable to terrain conditions with karst collapse, and the damage to the geomorphic environment is relatively small.

[0004] In the above device and the traditional rock foundation structure of photovoltaic brackets, generally, concrete precast piers are embedded underground, so that multiple piers with the same level support the photovoltaic brackets. However, when the ground moves, it may cause a level difference in the multiple pre-embedded horizontal piers, and then cause a height difference at different positions of the photovoltaic brackets, resulting in the situation of pulling the brackets deformed.
