Description

Synchronous rectangular deep hole drilling machine with haunched horizontal cantilever and adapted to rock stratum Technical Field The invention relates to the field of anti-slide pile drilling machine equipment, in particular to a synchronous rectangular deep hole drilling machine with a haunched horizontal cantilever, which is suitable for rock strata. 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. Therefore, the mechanical drilling of pile holes with the horizontal cantilever rectangular anti-slide piles in the rock and soil layers has important significance for ensuring the safety of constructors and improving the efficiency. At present, rectangular drilling equipment and excavation modes are various, for example: The patent number CN 106836354A 'rectangular anti-slide pile mechanical pore-forming device' is characterized in that a rectangular shovel head is formed by a plurality of cutting blades, and a counterweight or a hydraulic propulsion device is arranged at the rear end of the shovel head to drill rectangular pile holes. 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 number CN 104533300A rectangular drilling machine is characterized in that a conical drill bit is arranged at the bottom of a rectangular transmission case, cross-shaped long cutters are arranged on four sides of the rectangular transmission case, the conical drill bit drills to form a circular pile hole, and then the circular pile hole is trimmed into a rectangular pile hole through rotary cutting of the cross-shaped long cutters. 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 soil around the round pile hole is cut through the rectangular drilling cylinder to form a rectangular pile hole. The patent No. CN 105951798A, a rectangular drilling machine, mainly uses a motor to drive four concave waist cylinders with stirring blades to cut soil body, and drills rectangular pile holes. 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 holes with the horizontal cantilever and the haunched horizontal cantilever structure cannot be drilled in the soil body, and the drilling in rock bodies (broken stone, pebble, hard rock and other strata) cannot be realized; (2) The rectangular pile holes of the horizontal cantilever structure and the vertical pile body cannot be synchronously drilled in the rock body; (3) 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.
