Description

Technical Field

[0001] The utility model relates to the technical field of retaining wall slotting machine equipment, in particular to a double-rotating horizontal cantilever retaining wall multi-crawler drill. Background Art

[0002] In slope support, roadbed construction and other projects, 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 the lateral thrust, and control engineering and geological disasters. They are widely used in various engineering fields. The cross-section of traditional retaining walls is large, and the strength of the rock and soil in front of the retaining wall cannot be fully utilized. For retaining walls with horizontal cantilever plate structures, the horizontal cantilever plate can fully utilize the strength of the rock and soil in front of the retaining wall and improve the anti-sliding ability of the retaining wall. However, it is extremely difficult to make holes in the horizontal cantilever plate of the retaining wall with horizontal cantilever plate. Traditional 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 of retaining wall holes with horizontal cantilever plates in the rock and soil layer is of great significance to ensure the safety of construction personnel and improve efficiency.

[0003] Existing slotting technologies mainly include bucket type and milling wheel type. Patent No. CN 114687393A "A continuous wall construction equipment and construction method" uses a rotary drill and grab bucket to circulate and drill underground continuous wall grooves. Patent No. CN 110258693A "A hydraulic grab bucket and underground continuous wall construction equipment" uses active buckles and connectors to switch between hydraulic grab buckets and double-wheel milling, achieving multiple uses of one machine to drill underground continuous wall grooves. In order to realize the construction of ground-connected walls 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 modules, slurry extraction modules, winding modules and accessory reel modules, and connects them from front to back and lays them on the track; patent number CN115070953A "A slotting equipment for underground continuous wall construction in construction projects" installs the synchronous milling and hydraulic cutting equipment between two carrying vehicles through a frame to prevent the slot hole caused by the carrying vehicle from collapsing due to lateral pressure, thereby improving the slotting quality and slot hole stability. Patent No. CN 216108696 U "A Truss Chain Milling and Mixing Ground Wall Machine" and Patent No. CN 115897551 A "A Continuous Wall Construction Equipment and Construction Method Based on TRD Drilling Rig" both set a chain with multiple milling heads evenly distributed on the trusses with active and passive drive mechanisms at both ends, and drive the chain with milling heads to drill the ground wall slots through the active drive mechanism. Although the existing ground wall slotting machine has solved some ground wall slotting problems, the following problems still exist: (1) The soil pressure on the inner side of the retaining wall will cause the contact position between the retaining wall and the embedded section to bulge; (2) The strength of the rock and soil of the embedded section of the retaining wall cannot be fully utilized to resist the deformation of the retaining wall caused by the soil pressure; (3) The anchoring depth of the retaining wall is too large, resulting in excessively high construction costs; (4) It is impossible to realize the construction of horizontal cantilever plate structure holes in the rock and soil. Summary of the invention

[0004] The purpose of the utility model is to provide a double-rotating horizontal cantilever retaining wall multi-track drill based on the above-mentioned deficiencies of the prior art, which is composed of a rotating orthogonal track drill assembly and a cross-cutting track drill. Vertical wall holes are drilled in the rock and soil by rotating the orthogonal track drill assembly and the cross-cutting track drill, and horizontal cantilever plate holes are drilled on both sides of the vertical wall holes by rotating the orthogonal track drill assembly; the horizontal cantilever plate can make full use of the strength of the rock and soil in front of the retaining wall to improve the anti-slip ability of the retaining wall; reduce the anchoring length of the 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.

[0036] like Figures 1 to 5As shown, the U-shaped steel frame 3 is composed of a left guard plate 31, a right guard plate 32 and a front guard plate 33, and a drill hole 34 is provided on each of the left guard plate 31 and the right guard plate 32 to allow the rotating orthogonal crawler drill assembly 1 (rotating orthogonal crawler drill 11) to pass through. The lifting assembly 4 includes a cable fixing frame 41, a hanging beam 42, a cable motor 43 and a cable 45. The cable fixing frame 41 is fixed to the bottom surface of the hanging beam 42, and the cable motor 43 is fixed to the hanging beam 42 via the cable motor shaft 44 thereon.

The steps of the construction method of the retaining wall hole are as follows:

[0041] The horizontal directions of the two rotating orthogonal crawler drills 11 are both located in the U-shaped steel frame 3. At this time, the rotating motor fixed axis 1112 of the rotating orthogonal crawler drill 11 is set horizontally, and the rotating orthogonal crawler drill 11 and the cross-cutting crawler drill 2 are controlled to drill the vertical bore hole c1 downward until the designed depth of the vertical bore hole c1, and the vertical bore hole c1 is drilled horizontally by the cross-cutting crawler drill 2 (along the length direction of the vertical wall hole c3) to obtain the vertical wall hole c3. The multi-track drill a is lifted upward to move the rotating orthogonal track drill assembly 1 to the designed depth of the horizontal cantilever plate hole c4. The two rotating motors 129 respectively drive the two rotating orthogonal track drills 11 to rotate 90 degrees. At this time, the rotating motor fixed axis 1112 of the rotating orthogonal track drill 11 is vertically arranged.
