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-horizontal cantilever anti-sliding pile or retaining wall double crawler drill. Background Art

[0002] In projects such as 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 strata below the sliding surface, resist lateral thrust, and control engineering and geological disasters. Rectangular cross-section anti-slide piles are widely used in various engineering fields.

[0003] Traditional rectangular cross-section anti-slide piles or retaining walls have a large cross-section and cannot fully utilize the strength of the rock and soil in front of the pile or wall. For anti-slide 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 pile or wall and improve the anti-slide ability of the anti-slide pile or retaining wall, but it is extremely difficult to drill the horizontal cantilever holes of the anti-slide pile or retaining wall with horizontal cantilever. Traditional rectangular cross-section anti-slide piles or retaining walls usually use manual excavation and mechanical excavation methods. 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 digging of anti-slide piles or retaining wall holes with horizontal cantilevers in the rock and soil layer is of great significance to ensure the safety of construction workers and improve efficiency.

[0004] 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: the existing drilling machines mainly form vertical rectangular piles or wall holes in the rock and soil, but there are the following problems: (1) it is impossible to drill anti-slip piles or retaining wall holes with horizontal cantilever structures in the rock and soil; (2) the vertical piles or walls and horizontal cantilevers in the rock and soil cannot be drilled in one time, and the drilling construction efficiency is low and the cost is high. Summary of the invention

[0005] The purpose of the utility model is to provide a double-horizontal cantilever anti-slip pile or retaining wall double crawler drill in accordance with the above-mentioned deficiencies of the prior art, which drills vertical pile holes / vertical wall holes in the rock body through an orthogonal crawler drill assembly, and drills horizontal cantilever plate holes on both sides of the vertical pile holes / vertical wall holes through the orthogonal crawler drill assembly, and the horizontal cantilever plate can make full use of the strength of the rock and soil in front of the anti-slip pile or retaining wall to improve the anti-slip ability of the anti-slip pile or retaining wall; reduce the anchoring length of the anti-slip pile or retaining wall, and save construction costs; the drilling of the horizontal cantilever plate holes does not require the assistance of other mechanical equipment, which saves construction period and construction costs, improves work efficiency, and ensures project quality and the safety of construction personnel.

[0040] like Figures 1 to 5 As shown, the U-shaped steel frame 2 is composed of a left guard plate 21, a right guard plate 22, a front guard plate 23 and a rear guard plate 24, and a drill hole 25 is provided on each of the left guard plate 21 and the right guard plate 22 to allow the orthogonal crawler drill assembly 1 (orthogonal crawler drill 11) to pass through.

The translation motor 124 drives the translation screw 123 to rotate, so as to drive the sliding block 125 to move along the length direction of the translation screw 123 , thereby realizing the horizontal movement of the orthogonal crawler drill 11 .

[0043] like Figures 1 to 7As shown, in this embodiment, a double crawler drill a is used to drill a retaining wall hole in a rock formation b. The steps of the retaining wall hole construction method are as follows:

[0044] The horizontal directions of the two orthogonal crawler drills 11 are both located inside the U-shaped steel frame 2, and the orthogonal crawler drills 11 are controlled to drill the vertical borehole c1 downward until the designed depth of the vertical borehole c1 is reached. The double crawler drill a is lifted upward to move the orthogonal crawler drill assembly 1 to the designed depth of the horizontal cantilever plate hole c4, and the translation motor 124 of the translation assembly 12 is used to control the two orthogonal crawler drills 11 to drill the horizontal borehole c2 outward. After the drilling of the group of horizontal boreholes c2 is completed, the translation motor 124 of the translation assembly 12 drives the two orthogonal crawler drills 11 to retreat into the U-shaped steel frame 2.

[0045] like Figure 8 As shown, the retaining wall includes a vertical wall e and a horizontal cantilever plate h. The horizontal cantilever plates h are respectively arranged on both sides of the vertical wall e, namely the first horizontal cantilever plate and the second horizontal cantilever plate. The sliding force T of the rock formation b acts on the retaining wall, and the moment of the sliding force T is M T , using the strength of the rock mass under the first horizontal cantilever plate, the first horizontal cantilever plate and the embedded rock mass generate an upward vertical reaction force F, and the moment of the vertical reaction force F is M F Moment M with sliding force T T On the contrary, the deformation capacity of the retaining wall is improved; the rock and soil on the second horizontal cantilever plate exerts gravity G on the second horizontal cantilever plate, and the moment M of gravity G G Moment M with sliding force T T The same is used to improve the pull-out resistance of the retaining wall.

[0046] The beneficial technical effects of this embodiment are:

[0047] (1) Drilling horizontal cantilever plate holes in rock bodies using orthogonal crawler drill assemblies;

[0048] (2) The horizontal cantilever plate can make full use of the strength of the anti-slide piles or the rock and soil in the embedded section of the retaining wall to resist the deformation of the retaining wall caused by soil pressure;

[0049] (3) The horizontal cantilever plate 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;

[0050] (4) Reduce the anchorage length of anti-slide piles or retaining walls to save construction costs;

[0051] (5) Vertical piles or walls and horizontal cantilever plates in rock and soil bodies can be drilled at one time, which improves construction efficiency and saves construction and equipment costs.

[0052] 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.
