Construction method of spiral steel pipe pile in photovoltaic power station

Abstract

The invention relates to the field of construction of photovoltaic power stations, and discloses a photovoltaic power station spiral steel pipe pile construction method. The construction method uses a total station for calibrating and adjusting pile positions on main axles after using GPS measuring equipment for quickly measuring and setting the pile positions, so that the positioning precision of the pile positions is guaranteed; a domestic general outdoor down-hole drill is refitted, so that the cost is low, the performance is reliable, and the safety is high; the propelling and rotating functions of the drill are used; and a self-made driving shaft is added at the front end of a revolving speed reducing box output shaft of the drill, so that a drill output shaft and a spiral steel pipe pile can be connected and disassembled more conveniently, the drilling construction requirements of the spiral steel pipe pile are satisfied, and the construction efficiency, reliability, safety and economy are greatly improved. The method is suitable for flat floors or mountains with slopes of not higher than 30 degrees, and is suitable for construction of the spiral steel pipe pile under the condition that the thickness of a remolded place soil layer is not smaller than a designed drilling depth.

Description

technical field [0001] The invention relates to the construction field of a photovoltaic power station, in particular to a construction method for a spiral steel pipe pile of a photovoltaic power station. Background technique [0002] In the construction of photovoltaic power stations, spiral steel pipe piles have been widely used as the basic components of photovoltaic supports and components. Taking a 10MW photovoltaic power station as an example, the number of spiral steel pipe piles is more than 18,000. [0003] In terms of measurement, traditional methods such as total stations, theodolites with range finders, etc., can no longer meet such a large number of measurement points in a short period of time (about half a month). High, but its positioning deviation is mostly as high as about 20mm, which cannot meet the requirements of the axis positioning of the pile foundation, and will inevitably cause thousands of upper photovoltaic brackets and components to be difficult ...

Problems solved by technology

If you use imported full hydraulic down-the-hole drilling rigs, or drilling rigs modified from medium and small excavators, you will pay high costs, and because the site of mountain photovoltaics has a large slope and complex terrain, the use of the above equipment is bound to be limited by the site; if The use of domestic open-air down-the-hole drilling rigs, although the cost is low and the requirements for the site are low, but so far, it cannot be directly used for the construction of on-site photovoltaic spiral steel pipe piles.
