Background
In the projects such as side slope support, roadbed construction, foundation pit excavation, tunnel entrance and exit construction and the like, the slide-resistant pile is the most effective measure capable of transmitting the side thrust of a rock-soil body into a stable stratum below a sliding surface, resisting the side thrust and treating the projects and geological disasters. The slide-resistant piles are divided into rectangular section slide-resistant piles and circular section slide-resistant piles. The rectangular anti-skid pile has the advantages of high lateral rigidity, high single pile bearing capacity and the like, and can effectively enhance the anti-skid force and improve the anti-skid coefficient. Therefore, rectangular-section slide piles are widely used in various engineering fields.
The traditional rectangular section slide-resistant pile has a larger section and can not fully utilize the strength of rock-soil mass in front of the pile. For the anti-slide pile with the horizontal cantilever structure, the horizontal cantilever can fully utilize the strength of rock and soil mass in front of the pile, so that the anti-slide capacity of the anti-slide pile is improved, but the hole forming difficulty of a horizontal cantilever pile hole of the rectangular anti-slide pile with the horizontal cantilever is extremely high. The traditional rectangular section slide-resistant pile adopts a manual excavation and mechanical excavation mode, collapse caused by manual hole digging pile construction accounts for 65% of the total number of collapse accidents, and the traditional rectangular section slide-resistant pile is low in efficiency, high in cost, and safer and more efficient in mechanical excavation. For broken rock and soil bodies such as soft soil, broken stone, pebbles and piled bodies, measures such as mud wall protection are needed when pile holes are excavated, and hole collapse is prevented. Therefore, the mechanical drilling of pile holes with the horizontal cantilever rectangular anti-slide piles in soft soil and broken rock and soil layers has important significance for ensuring the safety of constructors and improving the efficiency.

The patent number CN 103244053A rectangular drilling machine mainly drives T-shaped cutter heads uniformly distributed at the lower parts of two steel frames to move in opposite directions and reciprocate through two cam bodies, and cuts soil into rectangular holes.

The patent No. CN 207715083U, a rectangular anti-slide pile hole-forming drilling machine, mainly sets a round drilling cylinder and a rectangular drilling cylinder at the bottom of a drill rod, the round drilling cylinder is screwed into a round pile hole, and then the rectangular pile hole is formed by cutting soil around the round pile hole through the rectangular drilling cylinder.
The patent No. CN 105951798A "rectangular drilling machine" mainly uses motor to drive four concave waist cylinders with reamer to cut soil body, and uses motor to drill rectangular pile hole.
The existing drilling machine mainly forms vertical rectangular pile holes in a rock-soil body, but has the following problems: (1) The rectangular anti-slide pile hole with the horizontal cantilever or the haunched horizontal cantilever structure cannot be drilled in the soil, and the drilling in the soil such as soft soil, broken stone, pebbles, piles and the like cannot be realized; (2) Other machines (grab buckets) or auxiliary measures (a mud positive circulation deslagging method) are adopted to clean the slag soil in the pile holes, and the integration level of drilling and deslagging equipment is low, the drilling construction efficiency is low and the cost is high.
