In the projects such as side slope support, roadbed construction, foundation pit excavation, tunnel entrance and exit construction and the like, the slide-resistant pile is the most effective measure capable of transmitting the side thrust of a rock-soil body into a stable stratum below a sliding surface, resisting the side thrust and treating the projects and geological disasters. The slide-resistant piles are divided into rectangular section slide-resistant piles and circular section slide-resistant piles. The rectangular anti-skid pile has the advantages of high lateral rigidity, high single pile bearing capacity and the like, and can effectively enhance the anti-skid force and improve the anti-skid coefficient. Therefore, rectangular-section slide piles are widely used in various engineering fields.
The traditional rectangular section slide-resistant pile has a larger section and can not fully utilize the strength of rock-soil mass in front of the pile. For the anti-slide pile with the horizontal cantilever structure, the horizontal cantilever can fully utilize the strength of rock and soil mass in front of the pile, so that the anti-slide capacity of the anti-slide pile is improved, but the hole forming difficulty of a horizontal cantilever pile hole of the rectangular anti-slide pile with the horizontal cantilever is extremely high. The traditional rectangular section slide-resistant pile adopts a manual excavation and mechanical excavation mode, collapse caused by manual hole digging pile construction accounts for 65% of the total number of collapse accidents, and the traditional rectangular section slide-resistant pile is low in efficiency, high in cost, and safer and more efficient in mechanical excavation. Therefore, the mechanical drilling of pile holes with the horizontal cantilever rectangular anti-slide piles in the rock and soil layers has important significance for ensuring the safety of constructors and improving the efficiency.

The patent number CN 103244053A rectangular drilling machine mainly drives T-shaped cutter heads uniformly distributed at the lower parts of two steel frames to move in opposite directions and reciprocate through two cam bodies, and cuts soil into rectangular holes.
The patent number CN 104533300A rectangular drilling machine is characterized in that a conical drill bit is arranged at the bottom of a rectangular transmission case, cross-shaped long cutters are arranged on four sides of the rectangular transmission case, the conical drill bit drills to form a circular pile hole, and then the circular pile hole is trimmed into the rectangular pile hole through rotary cutting of the cross-shaped long cutters.
The patent No. CN 207715083U, a rectangular anti-slide pile hole-forming drilling machine, mainly sets a round drilling cylinder and a rectangular drilling cylinder at the bottom of a drill rod, the round drilling cylinder is screwed into a round pile hole, and then the rectangular pile hole is formed by cutting soil around the round pile hole through the rectangular drilling cylinder.
The patent No. CN 105951798A 'rectangular drilling machine' mainly uses a motor to drive four concave waist cylinders with stirring blades to cut soil body, and drills rectangular pile holes.
The existing drilling machine mainly forms vertical rectangular pile holes in a rock-soil body, but has the following problems: (1) The rectangular anti-slide pile hole with the horizontal cantilever structure cannot be drilled in the soil body, and the drilling in rock bodies (broken stone, pebble, hard rock and other strata) cannot be realized; (2) The rectangular pile holes of the horizontal cantilever structure and the vertical pile body cannot be synchronously drilled in the rock body; (3) Other machines (grab buckets) or auxiliary measures (a mud positive circulation deslagging method) are adopted to clean the slag soil in the pile holes, and the integration level of drilling and deslagging equipment is low, the drilling construction efficiency is low and the cost is high.

Description of the embodiments
The features of the present invention and other related features are described in further detail below by way of example in conjunction with the following drawings, to facilitate understanding by those skilled in the art:
examples: as shown in fig. 1-17, the embodiment specifically relates to a synchronous rectangular deep hole drilling machine with a horizontal cantilever, which is suitable for a rock stratum, the rectangular deep hole drilling machine comprises a drill carriage 9 and a drilling machine hoisted by a cable 93 on the drill carriage 9, the drilling machine sequentially comprises a pipeline fixing frame 6, a rock slag processing mechanism, a sliding horizontal drilling assembly 2 and a vertical drilling device 1 from top to bottom, wherein the rock slag processing mechanism comprises a stirring device 3, a crushing device 4, a slag sucking system 5, a slag discharging system 7 and a grouting system 8.
As shown in fig. 1, the drill carriage 9 includes a vehicle-mounted platform 911, a steel upright 97, a pull rod 910, a hinge shaft 99, a guide rail 98, a slide block 96, a steel cantilever beam 95, a cable bracket 94, a winch motor 91, a fixed shaft 92 and a cable 93, wherein the vehicle-mounted platform 911 is provided with a track wheel capable of running and is positioned on the ground, the steel upright 97 is vertically erected at the front end of the vehicle-mounted platform 911, the pull rod 910 forms a diagonal bracing reinforcement effect on the steel upright 97, and in particular, the upper end of the pull rod 910 is hinged with the upper end of the steel upright 97, and the lower end of the pull rod 910 is hinged with the hinge shaft 99 of the vehicle-mounted platform 911; the guide rail 98 is attached and fixed along the steel upright 97 to form a track in the vertical direction, and the sliding block 96 is slidably assembled on the guide rail 98 and can slide in the vertical direction under the drive of the power mechanism; the steel cantilever beam 95 is fixed on the sliding block 96, the cable support 94 is fixed on the bottom surface of the steel cantilever beam 95, the winch motor 91 is fixed on the steel cantilever beam 95 through the fixed shaft 92, and the winch motor 91 is used for driving the cable 93 and a drilling machine hoisted at the lower end of the cable 93 to do lifting motion. Moreover, the drilling machine can move downwards under the dead weight pressure of the drilling machine due to the fact that the dead weight of the drilling machine is large, the effect that a drill rod is required to be pressed downwards in the past is not needed, and the cable 93 has a sufficient length, so that the drilling requirement for a rectangular deep hole can be met.
As shown in fig. 1-9, the vertical drilling device 1 may be used for deep hole drilling of rectangular slide piles. The vertical drilling device 1 mainly comprises a plurality of cylindrical drilling assemblies 11 and a U-shaped fork plate 12 used as a mounting frame, wherein the U-shaped fork plate 12 mainly comprises a web 122 and wing plates 121 positioned on two sides of the web 122, and a steel support 123 is vertically welded in the middle of the web 122 based on the number of the cylindrical drilling assemblies 11. Each set of cylindrical drill assembly 11 is composed of two cylindrical drills, a motor 114 and a motor shaft 115, and in this embodiment, the number of cylindrical drills of the vertical drill device 1 is 4, and the cylindrical drills are distributed in a matrix to form rectangular cutting surfaces, and rectangular pile holes are formed in the downward cutting process. The cylindrical drill comprises a cylinder 111, a plurality of hob assemblies 113 distributed on the surface of the cylinder 111 at intervals, and a plurality of reamer assemblies 112 distributed between adjacent hob assemblies 113 on the surface of the cylinder 111 at intervals, a centrally arranged steel support 123 is welded or bolted with the shell of a motor 114, a motor rotating shaft 115 of the motor 114 drives the cylinders 111 on two sides to rotate, and the end parts of the motor rotating shaft 115 are supported in rotating shaft holes 124 of wing plates 121 on two sides. As shown in fig. 1-7, the height of the hob assembly 113 protruding above the cylinder 111 is higher than the reamer assembly 112, so that when cutting a rock mass, the hob 1132 on the hob assembly 113 first contacts the rock mass, i.e., the hob assembly 113 first breaks the rock face in its entirety into a plurality of large pieces of rock, and then further twists the large pieces of rock on the excavated face into small diameter rock pieces (or slag) by the reamer assembly 112; hob assembly 113 includes a hob base 1131 and a ring of hob 1132 secured to hob base 1131; the reamer assembly 112 includes a reamer base 1121 and a reamer 1122, and the reamer 1122 is in an inclined installation posture under the fixation of the reamer base 1121 to facilitate the reaming of a rock formation. For rock mass, if the hob 1132 is adopted to directly crush the rock mass of the excavated surface or the reamer 1122 is directly used for cutting, the strength, hardness and wear resistance of the hob and reamer materials are required to meet higher requirements, so that the development difficulty of the hob and reamer materials is increased, and the construction cost is increased. The hob 1132 and the reamer 1122 are combined, and the hob 1132 only fractures the rock mass of the excavated surface, so that the strength of the rock mass is reduced, the reamer 1122 is beneficial to cutting the rock mass more easily, the requirements on the strength, the hardness and the wear resistance of the hob and the reamer material can be correspondingly reduced, and the wear of the reamer and the hob can be reduced. Therefore, the method of combining the rock mass with the low strength after the hob 1132 is firstly used for fracturing the rock mass with the excavated face and then the reamer 1122 is used for cutting the rock mass with the low strength after the fracturing is adopted, so that the working efficiency can be improved, the cutter abrasion can be reduced, and the construction cost can be reduced.
