Technical Field
The utility model relates to the technical field of anti-slide pile or retaining wall drilling machine equipment, in particular to a double-track drill for double-rotation horizontal cantilever and sawtooth anti-slide piles or retaining walls.
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 or retaining wall is the most effective measure capable of transmitting the lateral thrust of a rock-soil body into a stable stratum below a sliding surface, resisting the lateral thrust and treating the projects and geological disasters, and is widely applied to various engineering fields. When landslide thrust acts on the slide-resistant pile or the retaining wall, the acting direction of the residual downward sliding force is not the horizontal direction, but a certain included angle is formed between the residual downward sliding force and the horizontal direction, and the included angle of most landslide is 10-30 degrees. According to the residual sliding force vector analysis, horizontal component force and vertical component force exist, the commonly adopted anti-sliding pile or retaining wall only resists the horizontal component force, and the vertical component force only acts on the anti-sliding pile or retaining wall and is transmitted to the sliding bed, so that the anti-sliding pile or retaining wall has no direct effect on the common anti-sliding pile or retaining wall. For the retaining wall with the cantilever ends of the slide-resistant piles or the retaining wall provided with a plurality of rows of zigzag force-distributing blocks, the force-distributing blocks can exert the vertical force-distributing of the rest sliding force, provide the same horizontal force to generate reverse bending moment, improve the bending resistance of the slide-resistant piles or the retaining wall, but the hole-forming difficulty of the force-distributing blocks of the zigzag slide-resistant piles or the retaining wall is extremely high. The traditional rectangular section slide-resistant pile or retaining wall has larger section and cannot fully utilize the strength of the rock-soil body in front of the pile or the wall. For the anti-slide pile or the retaining wall with the horizontal cantilever structure, the horizontal cantilever can fully utilize the strength of the rock-soil body in front of the pile or the wall, so that the anti-slide capacity of the anti-slide pile or the retaining wall is improved, but the hole forming difficulty of the horizontal cantilever hole with the horizontal cantilever anti-slide pile or the retaining wall is extremely high. The traditional anti-slide piles or retaining wall holes are usually excavated manually and excavated mechanically, collapse caused by manual hole digging pile construction accounts for 65% of total collapse accidents, and the anti-slide pile or retaining wall is low in efficiency, high in cost, safe and efficient in mechanical excavation. Therefore, the adoption of the mechanically drilled saw tooth anti-slide piles or retaining wall holes in the rock and soil layers has important significance for ensuring the safety of constructors and improving the efficiency.
