The invention relates to the related technical field of drilling machinery, and discloses a large-diameter forward and reverse drilling machine which comprises a rack, a propelling device used for propelling is arranged on the rack, a hydraulic motor is fixedly arranged on the propelling device, and a spiral drilling rod is fixedly installed on an output shaft of the hydraulic motor. The mud guards which are connected end to end are arranged on the inner side wall and the outer side wall of the auger of the spiral drill rod, and meanwhile the mud guards are fixedly arranged on the guide frame which is arranged on the spiral drill rod and slides from the surface of the auger, so that in the soil conveying process, the mud guards can be conveyed through continuous rotation of the spiral drill rod; according to the invention, the mud scraper is arranged on the spiral drill rod, so that the mud pushes the mud scraper to enable the mud baffle to slide on the spiral drill rod, meanwhile, the mud, attached to the auger, on the spiral drill rod can be scraped through the mud scraper, and the mud scraper is connected to the inner and outer side walls of the auger of the spiral drill rod in an end-to-end manner, so that the mud scraper circularly scrapes on the auger on the spiral drill rod; and finally, the adhered soil is scraped.
Description
technical field [0001] The invention relates to the related technical field of drilling machinery, in particular to a large-diameter forward and reverse drilling machine. Background technique [0002] The construction of large-scale pumped storage power stations mainly relies on the height difference characteristics of the upper and lower reservoirs in mountainous terrain to convert water into gravitational potential energy or electrical energy. The structures of a pumped storage power station generally include upper and lower reservoirs and pressure pipelines. Among them, the upper reservoir is built in the upper part of the mountain; the lower reservoir is arranged in the lower part of the mountain, using the existing or building a new reservoir; the pressure pipeline is built inside the mountain. At the same time, there are underground powerhouses for installing generators, surge chambers for power transmission and transformation, and tail water channels for power genera...
