Abstract

The invention provides a foundation pile for a photovoltaic bracket in a frozen soil area and a manufacturing method thereof, and belongs to the photovoltaic technical field. The manufacturing method comprises the following steps in sequence: (A) a prefabricated pile body is manufactured at the construction site; and a hole is drilled in the mounting area of the foundation pile; (B) the precast pile body is put in the hole; and (C) fine stone concrete is injected in a gap between the precast pile body and the hole wall for grouting and solidification. The quality is more reliable; the curing time after casting of a cast-in-place pile can be saved to accelerate the construction progress; the accident of breakage of a precast pile foundation caused by excessive hardness of frozen soil is prevented; the purpose of reducing damage to the precast pile body by the frost heaving force of the frozen soil is achieved; and the safety of the pile body is protected.

Description

Technical field

[0001] The invention belongs to the field of photovoltaic technology, and in particular relates to a foundation pile used for a photovoltaic support in frozen soil areas and a manufacturing method thereof. Background technique

[0002] With the rapid development of the photovoltaic market, affected by the construction period, winter construction has become an inevitable trend in the severely cold and cold areas in the northeast, northwest and other northern regions. These areas are almost all frozen soil or seasonal frozen soil areas. During winter construction, due to the high hardness of the frozen soil layer and the strong frost heaving force, which is affected by the frozen soil, what kind of foundation form the photovoltaic support foundation adopts also becomes a technical problem. The pile foundation in the photovoltaic support foundation has almost become a trend due to its direct force, simple structure, material saving, and fast construction speed. Comm...
