Problems solved by technology

In order to improve the bearing capacity of anti-slide piles, square piles are usually used instead of round piles. Common construction methods include the combination of drill holes and manual excavation, and direct excavation with milling cutters. The former excavation speed is slow and the efficiency is low. The construction cost is high, and at the same time, there are great labor risks. The torque and impact carried by the milling cutter in the latter are too large, resulting in slow excavation efficiency and rapid damage to the milling cutter

Abstract

The invention discloses anti-slide pile drilling machine equipment and a drill bit. The drill bit comprises a square frame, a Lelo triangular base body, a guide Lelo triangular block, a cutting tooth assembly and a scraper. The guiding Lelo triangular block is arranged in the square frame and used for being connected with a transmission mechanism, the guiding Lelo triangular block is fixedly connected with the Lelo triangular base body, and the cutting tooth assembly is arranged on the end face, away from the guiding Lelo triangular block, of the Lelo triangular base body in a protruding mode. The scraper is arranged on the periphery of the Lelo triangular base body and used for scraping a pile hole. The drill bit can rapidly excavate square holes in rock-soil layer geology, and is high in tunneling efficiency and long in service life.

Description

technical field [0001] The present application relates to the field of pile construction machinery, in particular to an anti-sliding pile drilling rig equipment and a drill bit. Background technique [0002] Slope stability construction is often required for infrastructure construction in hilly areas. By driving anti-sliding piles into the slope area, the flexural and shear resistance of rock and soil layers can be improved to ensure slope stability. Anti-sliding piles are suitable for For shallow and medium-deep landslides, it can effectively prevent the slope from sliding. In order to improve the bearing capacity of the anti-sliding piles, square piles are usually used instead of round piles. Common construction methods include the combination of drilling rigs and manual digging, and direct excavation by milling cutters. The former excavation is slow and inefficient. The construction cost is high, and at the same time, there is a great risk of labor. The torque and impact...
