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 a double-rotating horizontal cantilever and sawtooth anti-sliding pile or retaining wall double crawler drill. Background Art

[0002] In slope support, roadbed construction, foundation pit excavation, and tunnel entrance and exit construction, anti-slide piles or 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 the retaining wall with multiple rows of sawtooth force blocks at the cantilever end of the anti-sliding pile or retaining wall, the force blocks can exert the vertical force of the remaining sliding force, provide the same horizontal force to produce the opposite bending moment, and improve the bending resistance of the anti-sliding pile or retaining wall, but it is extremely difficult to make holes for the force blocks of the sawtooth anti-sliding pile or retaining wall. The traditional rectangular cross-section anti-sliding pile or retaining wall has a large cross-section and cannot fully utilize the strength of the rock and soil in front of the pile or wall. For the anti-sliding pile or retaining wall with a horizontal cantilever structure, the horizontal cantilever can fully utilize the strength of the rock and soil in front of the pile or wall to improve the anti-sliding ability of the anti-sliding pile or retaining wall, but it is extremely difficult to make holes for the horizontal cantilever of the anti-sliding pile or retaining wall with a horizontal cantilever. Traditional anti-sliding pile or retaining wall holes are usually excavated manually and mechanically. The collapse caused by the construction of manually excavated piles 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 digging sawtooth 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.

[0004] In terms of mechanical hole-making methods, for example, patent No. CN 108678661 A "Square anti-slip pile hole-making method and square drill bit for hole-making" uses a circular drill bit of a rotary drilling rig to drill at least one row of circular guide holes in sequence along the length direction of the cross-section of the square anti-slip pile hole, and each row of circular guide holes is connected, and the side walls of the square anti-slip pile holes are tangent to the edges of the adjacent circular guide holes. Then, a square drill bit is used to sweep the hole so that the square drill bit cuts the remaining soil downward along the contour line of the square anti-slip pile hole, and the cycle is repeated until the design requirements are met. Patent No. CN110593753 A "Mechanical rapid hole-forming construction method for rectangular anti-sliding piles" first uses a rotary drilling auger round drill bit to drill pilot holes at the four corners until the pilot holes are drilled to the designed pile bottom elevation; then the pilot holes are trimmed in three parts using a slotting machine, and the construction is carried out in three grabs: the first time, the pilot hole position along the long side of the anti-sliding pile is grabbed until the designed hole depth; the second time, the pilot hole position along the other long side of the anti-sliding pile is grabbed until the designed hole depth; the third time, the remaining part in the middle is grabbed until the designed hole depth. If encountering complex and hard strata such as hard ginger stone soil and calcareous cementation layer, the slotting machine stops grabbing the soil, and the hard layer is crushed with a long-arm breaker. Patent No. CN 110820733 A "An improved simple rectangular anti-sliding pile mechanical rapid hole-forming construction method" mainly uses two rotary excavations of circular pile holes, the circular pile holes are connected and over-excavated over the rectangular pile hole contour, and a rectangular steel cylinder is placed in the pile hole and the over-excavated part is cast to form a rectangular pile hole. Patent No. CN 110714460A "A Mechanical Hole Construction Method for Rectangular Anti-sliding Piles with Reduced Filling Coefficient" and Patent No. CN 113605387 "A Fully Mechanical Construction Method for Rectangular Anti-sliding Piles" are mainly to form rectangular pile holes by rotary excavating circular pile holes twice or more, the circular pile holes are connected or partially overlapped and tangent to the rectangular pile hole contour, and the rectangular pile holes are formed by mechanically removing slag and repairing holes around the pile holes. The existing slotting construction method, Patent No. CN 115288115 A, uses a slotting machine to grab and excavate the rock and soil in the slotted holes to form a continuous ground wall after excavating the vertical slots at intervals. Patent No. CN 115094915 A "A method for constructing a trench for underground continuous wall in slightly weathered volcanic rock" arranges the lead holes as required in the first opening unit and the closing unit, first drills the lead holes, then mills the rocks between the lead holes to achieve trenching, and during construction, multiple construction units are alternately constructed. After one construction unit completes the drilling of the lead holes, the rock between the adjacent lead holes of the construction unit is milled, and the lead holes of another construction unit are drilled at the same time, realizing a reasonable combination of drilling and milling and cyclic alternating trenching. Patent No. CN 114658050 A "Construction method for trenching of underground continuous wall containing medium-weathered rock formations" adjusts the drilling rig drilling hole spacing to 2 m, and then uses a double-wheel milling machine for trenching construction. When milling the trench, the two drums rotate at a low speed in opposite directions, and the milling teeth mill and crush the rock formation, and the rock slag and mud excavated by the drill are discharged to the ground mud station through the sand suction port in the middle of the milling wheel, and the cycle is repeated until the final hole is trenched.Patent No. CN 114687393A "A continuous wall construction equipment and construction method thereof" uses a rotary drill and a grab bucket to drill and dig a ground continuous wall groove in a combined cycle.

[0005] Although the existing anti-slip pile or retaining wall trenching machines have solved some hole-forming and trench-forming problems, the following problems still exist: (1) The existing drilling rigs mainly form vertical rectangular pile holes or wall trenches in the rock and soil, and cannot drill force block holes and horizontal cantilever structure holes in the rock and soil; (2) Other machinery or auxiliary measures are required to repair the holes, which results in low drilling efficiency and high cost, and it is impossible to drill trenches or holes in one go; (3) Anti-slip pile or retaining wall holes require auxiliary equipment to clean the debris in the pile holes or trenches, and the drilling and slag removal equipment has a low integration level, resulting in low drilling efficiency and high cost.
