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.

The invention provides a blade measurement base preparation method. The preparation method comprises the following steps of A, providing a casting device which comprises a casting base, a fixed locating block and a movable locating block; B, casting a low-melting-point alloy, cooling and solidifying the low-melting-point alloy and taking out a blade; and C, providing a cutting device and cutting an alloy part wrapping a locking plate groove at the bottom of tenon teeth through an electric heating wire to complete preparation of the rectangular block. Through the blade measurement base preparation method provided by the invention, a standard base is prepared, the measurement period of blades can be greatly shortened, and meanwhile, the production cost and the maintenance cost can be reduced.

The invention discloses a manufacturing method for a pedestal used for blade measuring, and the pedestal is a rectangular block which is cast from a low-melting-point alloy, and surrounds tenon teeth.The manufacturing method comprises the following steps: step A, providing casting equipment and fixing blades; step B, pouring the low-melting-point alloy into the casting cavity, and taking out theblades with the rectangular block when the low-melting-point alloy is quickly condensed; and step C, providing cutting equipment, utilizing an electric heating wire to cut an alloy part which coats alocking sheet slot, thereby accomplishing manufacturing of the rectangular block. According to the manufacturing method for the pedestal used for blade measuring provided by the invention, the standard pedestal is manufactured, so that the measuring work-period of the blades can be greatly shortened; and meanwhile, production cost and maintenance cost can be reduced.

The invention discloses a method for manufacturing the blade casting measurement block. The method for manufacturing the blade casting measurement block comprises the following steps of A, providing acasting device, and fixing the blade; B, pouring a low-melting-point alloy in a casting cavity; and C, providing a dissolution shaping device, wherein the dissolution shaping device comprises a shaping base, the shaping base is provided with a working cavity, at least one hot oil nozzle pointing to the upper part in the working cavity is arranged on the side wall of the working cavity, so that the hot oil nozzle sprays hot oil with the temperature not lower than 180 DEG C to a rectangular block, and after the alloy to be covered with a lock sheet groove area is melted by hot oil, the preparation of the rectangular block is completed. According to the method for manufacturing the blade casting measuring block, the standardized measuring blocks are prepared in batches, so that the measurement period of the blade can be greatly shortened, meanwhile, the production cost and the maintenance cost can be reduced.

A blade casting measuring block manufacturing apparatus comprises a casting device for casting a blank of a rectangular block and a dissolution shaping device for shaping the blank of the rectangularblock. The blade casting measuring block manufacturing apparatus can greatly shorten the measuring period of the blade by manufacturing the standardized measuring blocks in batches, and can reduce theproduction cost and the maintenance cost.
