Embodiment 1

[0036] see Figure 1-4 , a prefabricated barrel-shaped foundation for photovoltaic support in the shallow surface soil layer area, including a barrel-shaped foundation 1, the barrel-shaped foundation 1 is a hollow barrel-shaped foundation 1 with prefabricated steel bars 16 concrete, by adopting the barrel-shaped structure, With a small amount of concrete, the contact area between the foundation and the soil is enlarged to ensure that the foundation has sufficient bearing capacity.

[0037] The barrel-shaped foundation 1 specifically includes two parts: a barrel wall 11 and a barrel roof 12. The barrel wall 11 is arranged below the barrel roof 12; the barrel wall 11 and the barrel roof 12 are provided with steel bars 16 for reinforcement. Preferably, due to the barrel shape The force of the foundation 1 is mainly the overall force, and the reinforcement of the foundation is structural reinforcement. It is recommended to use φ10 for the 12 steel bars 16 of the barrel roof, and φ...

Embodiment 2

[0056] The second embodiment is the application of a prefabricated barrel-shaped construction method for the photovoltaic support 2 in the shallow surface soil layer in a certain ash field photovoltaic power station in Northwest China.

[0057] The thickness of the superficial filling layer of the ash yard is about 0.6m; using the barrel foundation 1, specifically, the diameter of the barrel foundation 1 is 0.5m, the depth of entry is 0.4m, and the thickness of the barrel roof 12 is 0.2m. The total height of the barrel foundation 1 is 0.6m.

Abstract

The invention discloses a shallow surface soil layer area photovoltaic support prefabricated barrel-shaped foundation and a design method. The prefabricated barrel-shaped foundation comprises a barrel wall and a barrel top plate, and the barrel wall is arranged below the barrel top plate; steel bars are arranged in the barrel wall and the barrel top plate; an embedded bolt and an air hole are arranged in the barrel top plate, the threaded section of the embedded bolt is higher than the upper surface of the barrel top plate, and the embedded bolt is connected with a photovoltaic support to realize the fixation of the photovoltaic support; and a boot plate is arranged below the barrel wall. The barrel-shaped foundation interacts with foundation soil to provide anti-pulling, anti-pressing and anti-horizontal bearing capabilities; the foundation is ensured to have enough bearing capacity, and the cost of foundation engineering is reduced; and through factory prefabrication and standardized batch production, the foundation quality is improved, the construction period is shortened, and the foundation is very suitable for shallow surface soil layer area photovoltaic power station engineering.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering and foundations, in particular to a prefabricated barrel-shaped foundation and a design method for a photovoltaic support in a shallow surface soil layer area. Background technique [0002] Photovoltaic power generation technology is an important part of new energy power generation technology and an important energy engineering technology for my country to achieve the goal of 3060 carbon peak and carbon neutrality. The principle is to use the photovoltaic effect of the semiconductor interface to directly convert light energy into electrical energy. Photovoltaic support is a structure that supports solar photovoltaic power generation components. Its foundation requires good load-bearing characteristics, and the construction is fast and convenient. [0003] Photovoltaic power station projects with shallow surface soil layers (photovoltaic power station projects on sites such as ash...
