Full-blade spiral drilling machine and PHC tubular pile foundation construction method

The invention discloses a full-blade spiral drilling machine and a PHC tubular pile foundation construction method, which relates to the technical field of fishing light complementary photovoltaic. .The PHC tubular pile foundation construction method is characterized by comprising the following steps: step S1, rechecking and protecting an original control network; step S2, measuring and distributing lines; step S3, determining a basic pile foundation; step S4, improving a drilling machine; step S5, boring a pile foundation; and step S6, carrying out the detection and acceptance. According to the invention, a novel full-blade spiral drilling machine is used to complete a task of drilling holes in a fishpond; when the holes are drilled in an underwater hard calcified layer, holes are formedwhile drilling, the drilling speed is gradually increased, and the hole forming time is reduced to 3 minutes per one foundation; and a novel drill bit has the advantages that the requirement for the skills of the operation pe
