Description

Technical Field

[0001] The utility model relates to the technical field of anti-slip pile or retaining wall groove forming machine equipment, in particular to an anti-slip pile or retaining wall double crawler drill with a horizontal boss and a variable sawtooth angle. 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. The collapse caused by manual bored pile construction accounts for 65% of the total collapse accidents, and the efficiency is low and the cost is high. Mechanical excavation is safer and more efficient. Therefore, the use of mechanical drilling and excavation with horizontal cantilever and variable sawtooth angle anti-sliding piles or retaining wall holes in the rock and soil layer is of great significance to ensure the safety of construction personnel 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 walls in low clearance, patent number CN 114086618A "A modular milling groove device for underground ground-connected wall construction" modularizes the functional components of the ground-connected wall groove forming equipment into milling and cutting modules, slurry extraction modules, winding and hanging 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 mixing 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 and stirring heads evenly distributed on a truss with active and passive driving mechanisms at both ends, and the chain with milling and stirring heads is driven by the active driving mechanism to drill the ground-connected wall grooves. Although existing anti-slip pile or retaining wall trenching machines have solved some hole-making and trench-making problems, the following problems still exist: (1) Existing drilling rigs mainly form vertical rectangular pile holes or wall trenches in the rock and soil, and are unable to drill force block holes and horizontal cantilever structure holes in the rock and soil; (2) The residual sliding force of different slopes has different angles with the horizontal, and it is impossible to drill force block holes with the optimal vertical force component angle with the residual sliding force; (3) Other machinery or auxiliary measures are required to repair the holes, the drilling construction efficiency is low and the cost is high, and it is impossible to drill trenches or holes in one go; (4) Anti-slip pile or retaining wall holes require auxiliary equipment to clean the debris in the pile holes or trenches, the drilling and slag removal equipment has a low integration level, and the drilling construction efficiency is low and the cost is high.

The vertical component of the remaining sliding force provides a bending moment in the opposite direction of the horizontal force, and according to the direction of the remaining sliding force of different slopes, the force block hole with the optimal angle to the vertical component of the remaining sliding force is drilled; at the same time, the horizontal boss can make full use of the strength of the rock and soil in front of the anti-sliding pile or retaining wall, improve the bending and sliding resistance of the anti-sliding pile or retaining wall; reduce the anchoring length of the anti-sliding pile or retaining wall, and save construction costs; the drilling and slag discharge equipment is highly integrated, saving construction time and construction costs, improving work efficiency, and ensuring project quality and the safety of construction personnel.

The orthogonal crawler drill assembly 1 can be moved horizontally, that is, the horizontal direction of the orthogonal crawler drill assembly 1 can be moved outside the U-shaped steel frame 4 to drill horizontal boss holes in the rock and soil to form horizontal bosses. The conical drill assembly 3 is used to drill force-dividing block holes to form force-dividing blocks, and the horizontal angle of the conical drill assembly 3 is adjustable. The horizontal angle of the conical drill assembly 3 here refers to the horizontal angle between the conical drill 31 of the conical drill assembly 3 and the conical drill U-shaped steel frame 32 of the conical drill assembly 3. The slag removal system 33 is used to remove soil slag generated when drilling the rock and soil.

[0051] like Figures 1 to 7 As shown, the U-shaped steel frame 4 is composed of a left drill guard plate 41, a right drill guard plate 42 and a front drill guard plate 43, and a drill hole 44 is provided on the right drill guard plate 42 to allow the orthogonal crawler drill assembly 1 (orthogonal crawler drill 11) to pass through.
