Description

Technical Field

[0001] This invention belongs to the field of anti-slide pile drilling equipment, specifically relating to an asynchronous rectangular deep hole drilling rig with a haunch-type horizontal cantilever adapted to rock formations. Background Technology

[0002] In engineering projects such as slope protection, roadbed construction, foundation pit excavation, and tunnel entrance / exit construction, anti-slide piles are the most effective measure to transfer the lateral thrust of the soil and rock mass to the stable strata below the sliding surface, resisting lateral thrust and mitigating engineering and geological hazards. Anti-slide piles are divided into rectangular cross-section anti-slide piles and circular cross-section anti-slide piles. Rectangular anti-slide piles have advantages such as high lateral stiffness and high single pile bearing capacity, effectively enhancing anti-slide force and increasing the anti-slide coefficient. Therefore, rectangular cross-section anti-slide piles are widely used in various engineering fields.

[0003] Traditional rectangular cross-section anti-slide piles have large cross-sections and cannot fully utilize the strength of the soil and rock in front of the pile. For anti-slide piles with horizontal cantilever structures, the horizontal cantilever can fully utilize the strength of the soil and rock in front of the pile, improving the anti-slide capacity of the pile. However, drilling the horizontal cantilever pile holes for rectangular anti-slide piles with horizontal cantilever structures is extremely difficult. Traditional rectangular cross-section anti-slide piles are usually excavated manually or mechanically. Collapses caused by manual excavation account for 65% of all collapse accidents, and it is inefficient and costly. Mechanical excavation is safer and more efficient. Therefore, using mechanical drilling to excavate pile holes for rectangular anti-slide piles with horizontal cantilever structures within soil and rock layers is of great significance for ensuring the safety of construction personnel and improving efficiency.

[0004] Currently, there are various rectangular drilling rigs and excavation methods, such as:

[0005] Patent No. CN 106836354 A, "Mechanical Hole Forming Device for Rectangular Anti-slide Piles", uses multiple cutting blades to form a rectangular shovel head. The rear end of the shovel head is equipped with a counterweight or hydraulic propulsion device to realize the drilling of rectangular pile holes.

[0006] Patent No. CN 103244053 A "Rectangular Drilling Machine" mainly uses two cam bodies to drive two T-shaped cutter heads evenly distributed at the bottom of two steel frames to move towards each other and back and forth, cutting the soil into rectangular holes.

[0007] Patent No. CN 104533300 A, "Rectangular Drilling Machine", has a conical drill bit at the bottom of a rectangular transmission box and cross-shaped long cutters on the four sides. The conical drill bit drills in to form a circular pile hole, and then the cross-shaped long cutters rotate and cut to shape it into a rectangular pile hole.

[0008] The patent number CN 207715083 U, "A Rectangular Anti-slide Pile Drilling Rig", mainly involves setting a circular drill cylinder and a rectangular drill cylinder at the bottom of the drill rod. The circular drill cylinder is screwed in to form a circular pile hole, and then the rectangular drill cylinder cuts the soil around the circular pile hole to form a rectangular pile hole.

[0009] Patent No. CN 105951798 A, "A Rectangular Drilling Machine", mainly uses a motor to drive four concave cylindrical cutters with awls to cut the soil and drill rectangular pile holes.

[0010] Existing drilling rigs mainly form vertical rectangular pile holes in rock and soil, but they have the following problems:

[0011] (1) It is impossible to drill and excavate rectangular anti-slide pile holes with haunches and horizontal cantilever structures in the soil, and it is even more impossible to drill and excavate in rock masses (gravel, pebble, soft rock, hard rock and other strata);

[0012] (2) Other machinery (grab bucket) or auxiliary measures (slurry positive circulation slag removal method) are used to clean the slag in the pile hole. The integration of drilling and slag removal equipment is low, the drilling construction efficiency is low and the cost is high. Summary of the Invention

[0013] The purpose of this invention is to address the shortcomings of the prior art by providing an asynchronous rectangular deep-hole drilling rig with a haunched horizontal cantilever adapted to rock formations. This rig is hoisted using cables on a drilling rig to accommodate the required length of the deep hole, and utilizes its own weight to generate pressure for downward drilling. The rig asynchronously constructs rectangular deep-hole anti-slide piles with a haunched horizontal cantilever by controlling the haunched drilling assembly, the horizontal drilling assembly, and the vertical drilling device. Specifically, the vertical drilling device excavates the vertical rectangular pile hole using cylindrical drilling assemblies arranged in a matrix, and then the vertical rectangular pile hole is excavated to the level of the haunched horizontal cantilever. After reaching the designed depth, the vertical drilling device stops working. The axle drill assembly is then used to drill outwards to form the axle section. Then, the horizontal drilling device is driven by the horizontal hydraulic cylinder in the horizontal drilling assembly to extend laterally to drill a horizontal cantilever structure pile hole in the rock mass, thus forming a horizontal cantilever rectangular pile hole with axle. After that, the axle drill assembly is rotated back and the horizontal drilling assembly is retracted. Finally, the vertical drilling device continues to drill the rectangular pile hole to the designed depth. In addition, when the axle drill assembly, horizontal drilling assembly and vertical drilling device are twisting the rock strata, mud is injected into the pile hole through the grouting system to facilitate the suction of rock blocks mixed with mud.

[0066] The features and other related features of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments, so as to facilitate understanding by those skilled in the art:

[0067] Example: Figure 1-19 As shown, this embodiment specifically relates to an asynchronous rectangular deep hole drilling rig with a haunched horizontal cantilever adapted to rock formations. The rectangular deep hole drilling rig includes a drilling rig 10 and a drilling machine hoisted by a cable 103 on the drilling rig 10. The drilling machine includes a pipe fixing frame 7, a mud treatment mechanism, a haunched drilling assembly 3, a horizontal drilling assembly 2, and a vertical drilling device 1 connected sequentially from top to bottom. The mud treatment mechanism includes a mixing device 4, a crushing device 5, a slag suction system 6, a slag discharge system 8, and a grouting system 9.

[0068] like Figure 1As shown, the drilling rig 10 includes a vehicle-mounted platform 1011, a steel column 107, a tie rod 1010, a hinge shaft 109, a guide rail 108, a slider 106, a steel cantilever beam 105, a cable support 104, a winch motor 101, a fixed shaft 102, and a cable 103. The vehicle-mounted platform 1011 has tracked wheels and is located on the ground. The steel column 107 is vertically mounted at the front end of the vehicle-mounted platform 1011. The tie rod 1010 provides diagonal bracing reinforcement to the steel column 107. Specifically, the upper end of the tie rod 1010 is hinged to the upper end of the steel column 107. The lower end is hinged to the hinge shaft 109 of the vehicle platform 1011; the guide rail 108 is fixed along the steel column 107 to form a vertical track, and the slider 106 is slidably mounted on the guide rail 108 and can slide vertically under the drive of the power mechanism; the steel cantilever beam 105 is fixed on the slider 106, the cable bracket 104 is fixed on the bottom surface of the steel cantilever beam 105, and the winch motor 101 is fixed on the steel cantilever beam 105 via the fixed shaft 102. The winch motor 101 is used to drive the cable 103 and the drilling rig suspended at its lower end to perform lifting and lowering movements. It should be noted that, due to the large self-weight of the drilling rig, the drilling rig can move downward under its own weight without the need for the drill rod to press down as before, and the cable 103 has sufficient length to meet the drilling requirements of rectangular deep holes.

[0069] like Figure 1-8 As shown, the vertical drilling device 1 is used for drilling rectangular deep holes. It mainly includes several cylindrical drill assemblies 11 and a U-shaped fork plate 12 serving as a mounting frame. The U-shaped fork plate 12 mainly includes a web plate 122 and wing plates 121 located on both sides of the web plate 122. Based on the number of cylindrical drill assemblies 11, a steel support 123 is vertically welded to the middle position of the web plate 122. The cylindrical drill assembly 11 consists of two cylindrical drills, a motor 113, and a motor shaft 114. In this embodiment, there are four cylindrical drills arranged in a matrix to form a rectangular cutting surface. During the downward cutting process, a rectangular pile hole is formed. The matrix distribution here refers to the arrangement of cylindrical drills on both sides of the steel support 123. The cylindrical drill includes a cylinder 111, a plurality of hobbing cutter assemblies 113 spaced apart on the surface of the cylinder 111, and a plurality of reamer assemblies 112 spaced apart between adjacent hobbing cutter assemblies 113 on the surface of the cylinder 111. A centrally located steel support 123 is welded or bolted to the housing of a motor 114. The motor shaft 115 of the motor 114 drives the cylinders 111 on both sides to rotate, and the end of the motor shaft 115 is supported in the shaft holes 124 of the side flanges 121. Figure 5-8As shown, the height of the roller cutter assembly 113 protruding from the cylinder 111 is higher than that of the auger assembly 112. Therefore, when cutting the rock, the roller cutter 1132 on the roller cutter assembly 113 contacts the rock first. That is, the roller cutter assembly 113 first crushes the rock surface into several large rock blocks, and then the auger assembly 112 further cuts the large rock blocks on the excavation surface into small-diameter rock blocks (or rock debris). The roller cutter assembly 113 includes a roller cutter base 1131 and a ring of roller cutters 1132 fixed on the roller cutter base 1131. The auger assembly 112 includes an auger base 1121 and an auger 1122. The auger 1122 is installed at an angle under the fixation of the auger base 1121 to facilitate the excavation of rock strata. For rock masses, if the roller cutter 1132 directly crushes the rock mass at the excavation face or the auger 1122 directly excavates it, the strength, hardness, and wear resistance of the roller cutter and auger materials need to meet high requirements. This not only increases the difficulty of developing the roller cutter and auger materials but also increases construction costs. By combining the roller cutter 1132 and the auger 1122, the roller cutter 1132 only crushes the rock mass at the excavation face, reducing its strength. This makes it easier for the auger 1122 to cut the rock mass, thus reducing the requirements for the strength, hardness, and wear resistance of the roller cutter and auger materials, and also reducing wear on the cutter and auger. Therefore, the method of first crushing the rock mass at the excavation face with the roller cutter 1132, followed by cutting the crushed low-strength rock mass with the auger 1122, not only improves work efficiency but also reduces tool wear and lowers construction costs.

[0070] In addition, multiple vertical slag suction branch pipe through holes 125 and vertical grouting branch pipe through holes 126 are provided on the web plate 122. The vertical slag suction branch pipe through holes 125 facilitate the extension of the suction head 66 of the vertical slag suction branch pipe 62 in the slag suction system 6 into the U-shaped fork plate 12 to suck up the excavated rock slag. The vertical grouting branch pipe through holes 126 facilitate the vertical grouting branch pipe 93 of the grouting system 9 to pass through and extend into the U-shaped fork plate 12 for supplementary grouting, so as to mix with the cut and crushed rock slag to form mud fluid for easy suction by the vertical slag suction branch pipe 62.

[0071] like Figure 1-3As shown in Figures 9-11, the horizontal drilling assembly 2 is used for excavating horizontal cantilever pile holes, and mainly includes a horizontal drilling reaction frame 23, a horizontal hydraulic cylinder 22, and a horizontal drilling device 21. The horizontal drilling reaction frame 23 has a side-opening box-shaped structure, including a horizontal hydraulic reaction plate 234, a horizontal hydraulic upper side plate 232 installed above the horizontal hydraulic reaction plate 234, a horizontal hydraulic lower side plate 233 installed below the horizontal hydraulic reaction plate 234, and horizontal hydraulic side guard plates 231 installed on both sides of the horizontal hydraulic reaction plate 234, to form the aforementioned open box-shaped structure. The number of horizontal hydraulic cylinders 22 should ensure that they can stably push or retract the horizontal drilling device 21. In this embodiment, the horizontal drilling device 21 is provided with two sets, upper and lower, to realize the drilling of horizontal cantilever rectangular pile holes. Based on this, the number of horizontal hydraulic cylinders 22 is also set to two sets, upper and lower. The rear end of the cylinder of the horizontal hydraulic cylinder 22 is fixed on the horizontal hydraulic reaction plate 234. The front end of the piston rod of the horizontal hydraulic cylinder 22 is connected to the mounting frame of the horizontal drilling device 21 to drive it to move laterally horizontally in the open direction. Under the reaction force support provided by the horizontal drilling reaction frame 23, the horizontal hydraulic cylinder 22 drives the horizontal drilling device 21 forward to cut and excavate the rock mass to form a horizontal cantilever pile hole. After the horizontal cantilever rectangular pile hole is excavated, the horizontal hydraulic cylinder 22 drives the horizontal drilling device 21 to retract into the box-shaped space of the horizontal drilling reaction frame 23. It should be noted that the structure adopted by the horizontal drilling device 21 is the same as that adopted by the cylindrical drilling assembly 11, and it also uses a roller cutter assembly and a reamer assembly to adapt to rock formations. In addition, a slag suction main pipe through hole 235 is opened on the upper side plate 232 of the horizontal hydraulic system, and a horizontal slag suction branch pipe through hole 211 and a horizontal grouting branch pipe through hole 212 are opened on the mounting bracket partition of the horizontal drilling device 21. The slag suction main pipe 61 in the slag suction system 6 extends into the horizontal drilling reaction frame through the slag suction main pipe through hole 235. Within the box-shaped space of 23, the horizontal suction pipe 63 branching off from the main suction pipe 61 extends its suction head 66 into the horizontal drilling device 21 through the horizontal suction pipe through hole 211 to suck up the excavated mud (a mixture of rock debris and mud slurry); the horizontal grouting pipe 94 branching off from the main grouting pipe 91 extends to a location near the horizontal drilling device 21 through the horizontal grouting pipe through hole 212 to perform supplementary grouting, so as to mix with the cut and crushed rock debris to form mud slurry fluid, which is convenient for the horizontal suction pipe 63 to suck up.

[0072] like Figure 1-3As shown in Figures 12-15, the axle drill assembly 3 includes an axle drill device 31, a rotary hydraulic cylinder 32, a crank hydraulic cylinder 33, and an axle drill reaction frame 34; wherein: the axle drill reaction frame 34 includes an axle hydraulic reaction plate 344, axle hydraulic side guard plates 341 arranged on both sides of the axle hydraulic reaction plate 344, an axle hydraulic upper side plate 342 arranged on the top of the axle hydraulic reaction plate 344, and an axle hydraulic lower side plate 343 arranged at the bottom of the axle hydraulic reaction plate 344, so that the axle drill reaction frame 34 forms a box-shaped structure with a side opening. The axle drill assembly 31 is arranged within the box-shaped structure of the axle drill reaction frame 34 and located at its open portion. It includes axle drill wing plates 312, axle drill web plate 313, a U-shaped connector 311, and several axle drill assemblies. The axle drill wing plates 312 are arranged on both sides of the axle drill web plate 313 to form the mounting frame for each axle drill assembly. Each axle drill assembly is spaced apart on the vertical and top surfaces. The structure of the axle drill assemblies used here is the same as that used in the cylindrical drill assembly 11, and it also employs a cutter assembly and a reamer assembly to adapt to rock formations. The U-shaped connector 311 is located at the bottom of the axle drill web plate 313 and is used to hinge with the lower swing plate 345 on the axle hydraulic lower side plate 343. The U-shaped connector 311 includes a base plate 3111 and an upper swing plate 3112 welded to both sides of the base plate 3111. The base plate 3111 is fixedly connected to the bottom of the underarm drill web plate 313 and the bottom of the underarm drill wing plate 312. The upper swing plate 3112 is semi-circular and is hinged to the lower swing plate 345 via a connecting shaft 3114.

Since the rectangular deep hole drilling rig in this embodiment is applied to rock formations, the cut material is rock debris. The granular pure solid is difficult to pump and transport. Therefore, the main function of the grouting system 9 is to pump the supplemented mud to the cutting site, so that the rock debris and mud can be mixed for easy pumping. The grouting pump 92 is responsible for the pumping operation. Grouting pipe 91 extends from the ground into the axle drilling grouting 3, the horizontal drilling assembly 2, and the vertical drilling device 1.

[0080] like Figure 20 As shown in this embodiment, the construction method for asynchronous drilling of horizontal cantilever rectangular anti-slide pile deep holes with haunches using a rectangular deep-hole drilling rig in rock strata includes the following steps:

[0081] (S1) In the rock stratum a, the vertical drilling device 1 on the drilling rig b is used to drill vertical rectangular pile holes to form free section pile holes c, until the design depth of the horizontal cantilever pile hole e is reached.

[0082] During this process, the nozzle 96 on the vertical grouting branch pipe 93 is continuously opened through the vertical grouting valve 97 to inject mud, and the nozzle 96 on the horizontal grouting branch pipe 94 is closed through the horizontal grouting valve 98, and the nozzle 96 on the haunch grouting branch pipe 95 is closed through the haunch grouting valve 99.

[0083] At the same time, the suction head 66 of the vertical suction branch pipe 62 continues to suction slag, while the suction heads 66 of the horizontal suction branch pipe 63 and the axle suction branch pipe 64 are closed.

[0084] (S2) After reaching the design elevation of the horizontal cantilever pile hole e, stop the drilling work of the vertical drilling device 1; start the axle drill assembly 3, and under the drive of the rotating hydraulic cylinder 32 and the crank hydraulic cylinder 33, the axle drill device 31 gradually rotates outward around the connecting shaft 3114 and simultaneously performs rolling cutting of the rock stratum a until the axle drill device 31 rotates from the vertical state to the horizontal state, with a cumulative rotation of 90 degrees to form the axle hole d;

[0085] During this process, the nozzle 96 on the grouting branch pipe 95 is continuously opened through the grouting valve 99 to inject mud, and the nozzle 96 on the horizontal grouting branch pipe 94 is closed through the horizontal grouting valve 98, and the nozzle 96 on the vertical grouting branch pipe 93 is closed through the vertical grouting valve 97.

[0086] At the same time, the suction head 66 of the axle suction branch pipe 64 continues to suction slag, while the suction heads 66 of the horizontal suction branch pipe 63 and the vertical suction branch pipe 62 are closed.

[0087] (S3) After that, the horizontal drilling assembly 2 is turned on, and the horizontal hydraulic cylinder 22 drives the horizontal drilling device 21 to drill outward horizontally to the designed length position to form a horizontal cantilever pile hole e.

[0088] During this process, the nozzle 96 on the horizontal grouting branch pipe 94 is continuously opened through the horizontal grouting valve 98 to inject mud, and the nozzle 96 on the haunch grouting branch pipe 95 is closed through the haunch grouting valve 99, and the nozzle 96 on the vertical grouting branch pipe 93 is closed through the vertical grouting valve 97.

[0089] At the same time, the suction head 66 of the horizontal suction branch pipe 63 continues to suction slag, while the suction heads 66 of the axle suction branch pipe 64 and the vertical suction branch pipe 62 are closed.

[0090] (S4) After the construction of the axle hole d and the horizontal cantilever pile hole e is completed, the horizontal hydraulic cylinder 22 drives the horizontal drilling device 21 to retract inward to the minimum stroke, and the rotating hydraulic cylinder 32 and the crank hydraulic cylinder 33 drive the axle drilling device 31 to rotate back to the vertical state; then the vertical drilling device 1 continues to drill to the design depth to form the embedded section pile hole f. During this process, mud is continuously injected through the nozzle 96 of the vertical grouting branch pipe 93, and the nozzles 96 on the axle grouting branch pipe 95 and the horizontal grouting branch pipe 94 are closed; at the same time, the suction head 66 of the vertical slag suction branch pipe 62 continues to suction slag, while the suction heads 66 of the horizontal slag suction branch pipe 63 and the axle slag suction branch pipe 64 are closed.

[0091] The beneficial effects of this embodiment are:

[0092] (1) By using cables and retractable horizontal cylindrical drills with spaced cutters and rollers, and rotatable haunched cylindrical drills, rectangular pile holes with horizontal cantilever and haunched structures can be drilled in deep rock masses.

[0093] (2) The pile holes of the haunches, horizontal cantilever and vertical pile body can be formed in one go without other mechanical assistance, so as to improve construction efficiency and save construction and equipment costs;

[0094] (3) The rock is crushed twice by the crushing box, which can better discharge it from the pile hole and prevent the slag discharge pipe from being blocked;

[0095] (4) It has both drilling and slag removal functions, and the drilling rig has a high degree of integration, which realizes the uninterrupted synchronous operation of drilling and slag removal, reduces construction procedures, saves construction costs, and improves drilling efficiency.

[0096] Although the above embodiments have described the concept and embodiments of the present invention in detail with reference to the accompanying drawings, those skilled in the art will recognize that various improvements and modifications can still be made to the present invention without departing from the scope of the claims, and therefore will not be elaborated here.
