Description

Technical Field

[0001] The utility model relates to the technical field of anti-sliding pile or retaining wall drilling machine equipment, in particular to an anti-sliding pile or retaining wall hole-forming double crawler drill with horizontal bosses and saw teeth. Background Art

[0002] In slope support, roadbed construction and other projects, anti-slide piles / retaining walls are the most effective measures to transfer the lateral thrust of rock and soil to the stable stratum below the sliding surface, resist lateral thrust, and control engineering and geological disasters. They are widely used in various engineering fields. When the landslide thrust acts on the anti-slide piles or retaining walls, the direction of the residual sliding force is usually not horizontal, but at a certain angle to the horizontal direction. The angle of most landslides is between 10 and 30°. According to the residual sliding force vector analysis, there are horizontal and vertical components. The commonly used anti-slide piles or retaining walls only resist the horizontal component, and the vertical component only acts on the anti-slide piles or retaining walls to transfer to the sliding bed, and has no direct effect on ordinary anti-slide piles or retaining walls. For retaining walls with multiple rows of sawtooth force blocks at the cantilever end of the anti-slide piles or retaining walls, the force blocks can exert the vertical component of the residual sliding force, provide a bending moment in the opposite direction of the horizontal force, and improve the bending resistance of the anti-slide piles or retaining walls. However, it is extremely difficult to drill holes for the force blocks of sawtooth anti-sliding piles or retaining walls. The cross-section of traditional anti-sliding piles or retaining walls is large, and the strength of the rock and soil in front of the anti-sliding piles or retaining walls cannot be fully utilized. For anti-sliding piles or retaining walls with horizontal cantilever structures, the horizontal cantilever can fully utilize the strength of the rock and soil in front of the anti-sliding piles or retaining walls, and improve the anti-sliding ability of the anti-sliding piles or retaining walls. However, it is extremely difficult to drill holes for the horizontal cantilever of anti-sliding piles or retaining walls with horizontal cantilever structures. Traditional anti-sliding pile or retaining wall holes are usually excavated manually and mechanically. Collapses caused by manual bored pile construction account for 65% of the total collapse accidents, and are inefficient and costly. Mechanical excavation is safer and more efficient. Therefore, the use of mechanical drilling and digging of sawtooth anti-sliding piles or retaining wall holes in the rock and soil layer is of great significance to ensure the safety of construction workers and improve efficiency.

[0003] At present, there are various drilling equipment and mechanical excavation methods. For example, the existing anti-slip pile drilling machinery has patent number CN103244053 A "Rectangular Drilling Machine", which mainly drives two T-shaped cutters evenly distributed at the bottom of the two steel frames to move toward each other and reciprocate through two cam bodies to cut the soil into a rectangular hole. Patent number CN 104533300 A "Rectangular Drilling Machine" sets a conical drill bit at the bottom of the rectangular transmission box and a cross-shaped long knife on the four sides. The conical drill bit drills into a circular pile hole, and then the cross-shaped long knife is rotated and cut to trim it into a rectangular pile hole. Patent number CN 105951798 A "A Rectangular Drilling Machine" mainly drives four concave waist cylinders with stirring knives to cut the soil through a motor to drill into a rectangular pile hole. Existing retaining wall slotting technologies mainly include bucket type and milling wheel type. Patent number CN 114687393A "A Continuous Wall Construction Equipment and Construction Method" uses a rotary drill and a grab bucket to circulate and drill the ground-connected wall slot. Patent No. CN 110258693A "A hydraulic grab and underground continuous wall construction equipment" realizes the switching between the hydraulic grab and the double-wheel milling machine through movable buckles and connecting parts, achieving multiple uses of one machine for drilling and digging underground continuous wall trenches. In order to realize the construction of ground-connected wall in low clearance, patent number CN 114086618A "A modular milling slot device for underground ground-connected wall construction" modularizes the functional components of the ground-connected wall slotting equipment into milling and cutting modules, slurry extraction modules, coiling modules and accessory reel modules, and connects them from front to back and lays them on the track; patent number CN 216108696 U "A truss chain milling and stirring ground-connected wall machine" and patent number CN 115897551 A "A continuous wall construction equipment and construction method based on TRD drilling rig" are both equipped with a chain with multiple milling heads evenly distributed on the truss with active and passive drive mechanisms at both ends, and the chain with milling heads is driven by the active drive mechanism to drill the ground-connected wall slot. Although the existing anti-slip pile or retaining wall slotting machine has solved some hole and slotting problems. However, the following problems still exist: (1) Existing drilling rigs mainly form vertical rectangular pile holes or wall grooves in the rock and soil, and are unable to drill force block holes and horizontal cantilever structure holes in the rock and soil; (2) Other mechanical or auxiliary measures are required to repair the holes, resulting in low drilling efficiency and high cost, and it is impossible to drill a groove or hole in one go; (3) Anti-slip piles or retaining wall holes require auxiliary equipment to clean the debris in the pile holes or grooves, the drilling and slag removal equipment has a low integration level, and the drilling efficiency is low and the cost is high.

The sliding force T of the rock slope b acts on the retaining wall, and the sliding force T is decomposed into the vertical component force T of the sliding force. v and the horizontal component of the sliding force T h , the moment of the sliding force T is M T , the vertical wall e is used to block the horizontal component of the sliding force T h , the force block d is used to convert the vertical component of the sliding force T v Converted into torque M Tv , and the moment M Tv With torque M TOn the contrary, the bending resistance of the retaining wall is improved; by utilizing the strength of the rock and soil under the horizontal boss h, the horizontal boss h and the embedded rock and soil generate an upward vertical reaction force F, and the moment M of the vertical reaction force F F Moment M with sliding force T T On the contrary, the deformation capacity of the retaining wall is further improved.

[0059] The beneficial technical effects of this embodiment are:

[0060] (1) Through the conical drill assembly and the orthogonal crawler drill assembly, force block holes and horizontal boss holes can be drilled in the rock and soil to improve the bending and sliding resistance of anti-sliding piles or retaining walls;

[0061] (2) The horizontal boss can make full use of the strength of the rock and soil of the anti-sliding pile or the retaining wall embedded section to resist the deformation of the anti-sliding pile or retaining wall caused by soil pressure;

[0062] (3) The horizontal boss can eliminate the soil pressure inside the anti-sliding pile or retaining wall, which causes the anti-sliding pile or retaining wall to bulge at the contact point with the embedded section;

[0063] (4) Reduce the anchorage length of anti-slide piles or retaining walls to save construction costs;

[0064] (5) Vertical piles or walls, force blocks and horizontal bosses in the rock and soil body can be drilled at one time;

[0065] (6) The drilling and slag removal equipment is highly integrated, achieving the goal of improving construction efficiency and saving construction and equipment costs.

[0066] Although the above embodiments have described the concepts and embodiments of the purpose of the utility model in detail with reference to the accompanying drawings, ordinary technicians in this field can recognize that various improvements and modifications can still be made to the utility model without departing from the scope of the claims, so they are not described one by one here.
