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 drill with a horizontal boss. 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 drilling drill for anti-slip piles or retaining walls with horizontal bosses in accordance with the above-mentioned deficiencies of the prior art. The anti-slip pile holes or retaining wall holes are excavated in the rock and soil by the drilling drill. An orthogonal crawler drill assembly is provided on the drilling drill. Vertical holes and horizontal holes are drilled by the orthogonal crawler drill assembly to achieve drilling of vertical wall holes / vertical pile holes and horizontal boss holes in the rock and soil. The horizontal boss can make full use of the strength of the rock and soil in front of the anti-slip pile or retaining wall, thereby improving the anti-slip ability of the anti-slip pile or retaining wall; reducing the anchoring length of the anti-slip pile or retaining wall, thereby saving construction costs; the drilling of the horizontal boss does not require the assistance of other mechanical equipment, thereby saving construction period and construction costs, improving work efficiency, and ensuring project quality and the safety of construction personnel.

[0034] The following is a further detailed description of the features of the present invention and other related features through embodiments in conjunction with the accompanying drawings to facilitate understanding by technicians in the same industry:

[0035] Example: Figures 1 to 4 As shown, the present embodiment relates to a hole-forming drill for anti-slip piles or retaining walls with horizontal bosses, which mainly comprises a U-shaped steel frame 2, a lifting assembly 3 and an orthogonal crawler drill assembly 1, wherein the lifting assembly 3 is used for lifting the U-shaped steel frame 2, the orthogonal crawler drill assembly 1 is installed on the U-shaped steel frame 2, and the orthogonal crawler drill assembly 1 is horizontally arranged, with the bottom of the orthogonal crawler drill assembly 1 exposed outside the bottom of the U-shaped steel frame 2, and is used for drilling vertical wall holes or vertical pile holes in the rock and soil to form vertical walls or vertical piles, and 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 2, and is used for drilling horizontal boss holes in the rock and soil to form horizontal bosses.

[0036] like Figures 1 to 4As 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 the right guard plate 22 to allow the orthogonal crawler drill assembly 1 (orthogonal crawler drill 11) to pass through. The lifting assembly 3 includes a cable fixing frame 31, a hanging beam 32, a cable motor 33 and a cable 35. The cable fixing frame 31 is fixed to the bottom surface of the hanging beam 32, and the cable motor 33 is fixed to the hanging beam 32 via a cable motor shaft 34 thereon. The cable motor 33 is used to drive the cable 35 and the U-shaped steel frame 2 hoisted at its lower end to perform lifting and lowering movements to ensure the normal operation of the orthogonal crawler drill assembly 1. Among them, the cable 35 is respectively connected to the left guard plate 21 and the right guard plate 22 of the U-shaped steel frame 2.

[0037] like Figures 1 to 4 As shown, the orthogonal crawler drill assembly 1 includes an orthogonal crawler drill 11 and a translation assembly 12. The translation assembly 12 drives the orthogonal crawler drill 11 to move horizontally, that is, the translation assembly 12 drives the orthogonal crawler drill 11 to pass through the drill opening 25 and move outside the U-shaped steel frame 2 to drill a horizontal boss hole in the rock and soil. The orthogonal crawler drill 11 includes a rotating motor assembly 111, a crawler assembly 112 and a connecting plate 113. The rotating motor assembly 111 is composed of a rotating motor rotor 1111 and a gear ring 1113. Two gear rings 1113 are relatively arranged on the left and right, and the rotating motor rotor 1111 is fixed on the inner ring of the gear ring 1113. Two connecting plates 113 are relatively arranged on the front and back, and the two ends of the connecting plates 113 are respectively fixedly connected to the same end of the rotating motor fixed shaft 1112 of the two rotating motor rotors 1111. The connecting plate 113 is provided with an axial hole 122 corresponding to the rotating motor fixed shaft 1112, and the gear ring 1113 is provided with a plurality of teeth 1114 along the circumference of its outer ring. The track assembly 112 includes a track 1121 and a reamer assembly 1122. The track 1121 is annular and is provided with a plurality of teeth 114 along the circumference of the inner ring thereof. The teeth 114 on the track 1121 mesh with the teeth 114 on the outer ring of the gear ring 1113. The reamer assembly 1122 is evenly arranged along the circumference of the outer ring of the track 1121. The reamer assembly 1122 includes a reamer base 11221 and a reamer 11222 obliquely mounted on the reamer base 11221. The rotating motor rotor 1111 drives the gear ring 1113 to rotate, so as to drive the track 1121 to rotate, thereby driving the reamer 11222 of the reamer assembly 1122 to reamer the rock and soil. The oblique setting of the reamer 11222 is more conducive to reamer excavation of the rock and soil.

[0038] like Figures 1 to 4As shown, the translation assembly 12 includes a U-shaped driving frame 121, a translation motor 124, a sliding block 125 and a support seat 126. The support seat 126 and the translation motor 124 are respectively fixed on both sides of the U-shaped steel frame 2 (the left guard plate 21 and the right guard plate 22). The translation screw 123 on the translation motor 124 is rotatably connected to the support seat 126. The sliding block 125 cooperates with the translation screw 123 and is installed on the translation screw 123. The sliding block 125 is fixed on the middle part of the U-shaped driving frame 121. The two ends of the U-shaped driving frame 121 are respectively fixedly connected to the two ends of a rotating motor fixed shaft 1112. Both ends of the U-shaped driving frame 121 are provided with an axial hole 122 corresponding to the rotating motor fixed shaft 1112. 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.

[0039] like Figures 5 and 6 As shown, when constructing a retaining wall, a retaining wall hole is drilled in a rock formation b by a hole-forming drill a, and the hole-forming construction method includes the following steps:

[0040] A lifting assembly 3 and a U-shaped steel frame 2 are arranged on the hole drill a in sequence from top to bottom, and a horizontally arranged orthogonal crawler drill assembly 1 is installed in the U-shaped steel frame 2.

[0041] The horizontal direction of the orthogonal crawler drill 11 is located inside the U-shaped steel frame 2, and the orthogonal crawler drill 11 is controlled to drill the first vertical borehole c1 downward until the designed depth of the first vertical borehole c1 is reached. The hole-forming drill a is lifted upward, and the orthogonal crawler drill assembly 1 is moved to the designed depth of the horizontal boss hole c4. The translation motor 124 of the translation assembly 12 is used to control the orthogonal crawler drill 11 to drill the first horizontal borehole c2 outward; after the first horizontal borehole c2 is drilled, the orthogonal crawler drill 11 is retracted into the U-shaped steel frame 2 to drill the next vertical borehole c1 and horizontal borehole c2. This cycle is repeated until the last vertical borehole c1 and horizontal borehole c2 are drilled, thereby forming a vertical wall hole c3 and a horizontal boss hole c4, and completing the excavation of the retaining wall hole.

[0042] like Figure 7-8 As shown, when constructing anti-sliding piles, the hole construction method is the same as that of the retaining wall. The only difference is that a vertical pile hole c5 can be formed by drilling a vertical hole c1, and a horizontal boss hole c4 can be formed by drilling a horizontal hole c2, so it will not be described here.

[0043] The beneficial technical effects of this embodiment are:

[0044] (1) Drilling horizontal boss holes in rock and soil by using an orthogonal crawler drill assembly;

[0045] (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;

[0046] (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;

[0047] (4) Reduce the anchorage length of anti-slide piles or retaining walls to save construction costs;

[0048] (5) Vertical piles or walls and horizontal bosses in rock and soil bodies can be drilled at one time, which improves construction efficiency and saves construction and equipment costs.

[0049] 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.
