Description

Technical Field

[0001] The present invention relates to the technical field of drilling construction reinforcement, and particularly relates to a new type of drilling and hole-forming construction equipment for anchor cable support reinforcement. Background Art

[0002] In the fields of geotechnical engineering and civil engineering, anchor cable support reinforcement is an important construction technology, which is widely used in the support of slopes, foundation pits, tunnels and other projects. However, when the existing traditional drilling and hole-forming process and the pipe-following drilling process are applied in complex strata, many challenges and problems are faced.

[0003] Specifically, the traditional process requires repeated operations such as grouting, hole cleaning, and casing installation in complex strata, and even requires the use of eccentric bits or reaming bits for pipe-following drilling and hole-forming. These operations not only increase the complexity and cost of construction, but also result in a low hole-forming rate, and there are also problems of low efficiency such as time-consuming, labor-consuming, fuel-consuming, and material-consuming. For example, repeated grouting and hole cleaning will increase the construction time, and the use of eccentric bits or reaming bits may lead to the complication of drilling and hole-forming, exacerbate the time consumption, increase the material consumption and equipment maintenance cost. In addition, the hole-forming success rate of the traditional process is not high during the drilling process in complex strata, and it is difficult to install the anchor cable into the hole according to the design, thus affecting the construction quality and safety.

[0004] These problems not only reduce the construction efficiency, but also may lead to unstable engineering quality, and even the phenomenon of cutting corners, bringing potential safety hazards to the project. Therefore, there is an urgent need for a new type of drilling and hole-forming construction equipment that can improve the construction efficiency, reduce the construction cost, and ensure the construction quality and safety.

Detailed Embodiments

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Example 1:

[0033] Please refer to Figures 1 - 5 as shown in the figure. The present invention is a new drilling and hole-forming construction equipment for anchor cable support and reinforcement, including

[0034] a sleeve 1, and a drill bit mounting hole communicating with the inner cavity of the sleeve 1 is formed on the outer wall of the sleeve 1;

[0035] a drill bit assembly, the drill bit assembly is movably connected to the sleeve 1 through the drill bit mounting hole, the drill bit assembly includes a limit disc 4 movably arranged inside the cavity of the sleeve 1, plug shafts 5 and connecting shafts 6 are respectively fixedly connected to both ends of the limit disc 4, and a drill bit body 7 is fixedly connected to one end of the connecting shaft 6;

[0036] a mounting cover 8, the mounting cover 8 is hermetically connected to the drill bit mounting hole;

[0037] an impactor 12, one end of the impactor 12 is inserted into the plug shaft 5;

[0038] a drill pipe 13, one end of the drill pipe 13 is fixedly connected to the end of the impactor 12 away from the plug shaft 5;

[0039] wherein, a cable anchor fixing hole is formed on one side wall of the sleeve 1, an extrusion sleeve 14 is fixedly installed inside the cable anchor fixing hole, and a cable anchor body 15 is fixedly connected inside the extrusion sleeve 14;

[0040] a wire laying assembly for laying a plurality of cable anchor bodies 15 and a grouting pipe.

[0041] As can be seen from the above, through the unique drill bit assembly and sleeve design of the present invention, before drilling, the staff first opens the mounting cover 8, connects the drill bit assembly to the sleeve 1 through the drill bit mounting hole, and then fixes the mounting cover 8 on the sleeve 1 with a countersunk head screw 11; then fixes the extrusion sleeve 14 at one end of the cable anchor body 15 and installs it into the cable anchor fixing hole, arranges the grouting pipe between the cable anchor bodies 15, and then uses the outer ring 17 and the inner ring 16 to lay the cable anchor bodies 15 and the grouting pipe, and fixes the outer ring 17 and the inner ring 16 by screwing the fixing bolts into the internal thread holes 20. Then, connect one end of the impactor 12 to the drill pipe 13 of the drill rig, and the other end to the plug shaft 5 of the drill bit assembly, start the drill rig, the impactor 12 drives the drill bit body 7 to drill a hole, and at the same time brings the cable anchor body 15 into the drill hole. After drilling to the designed hole depth, the cable anchor is completed, and then the drill pipe 13 and the impactor 12 are withdrawn to separate them from the drill bit body 7. Finally, grouting is carried out into the drill hole through the grouting pipe;

[0042] The technical solution of the present invention realizes the integrated operation of drilling and installing the anchor cable, greatly improving the construction efficiency and reducing the construction processes and time. It has improved the problems of time-consuming, labor-consuming, fuel-consuming, material-consuming and low efficiency existing in the application of traditional drilling and hole-forming processes and pipe-following drilling processes in complex strata, and can effectively control the project quality and prevent the occurrence of cutting corners

[0043] Specifically, the new drilling and hole-forming construction equipment of the present invention realizes the rapid installation and disassembly of the drill bit assembly through the cooperation of the sleeve 1, the drill bit assembly, the mounting cover 8, the impactor 12 and the drill pipe 13. At the same time, the extrusion sleeve 14 arranged in the anchor cable fixing hole can firmly fix the anchor cable body 15, ensuring the stability of the anchor cable during the drilling process and preventing it from loosening or falling off. In addition, the setting of the wire laying assembly facilitates the laying of the anchor cable body 15 and the grouting pipe, making the construction process more efficient and orderly.

[0044] As Figures 1 - 2 can be seen, the drill bit mounting hole includes a shaft groove 2 opened on one side wall of the front end of the sleeve 1 and a placement groove 3 opened on the outer wall of the sleeve 1, and the shaft groove 2 is communicated with the placement groove 3.

[0045] The connecting shaft 6 is movably arranged in the shaft groove 2.

[0046] As can be seen from the above, this design of the drill bit mounting hole enables the drill bit assembly to be conveniently inserted into the interior of the sleeve 1, and the movable arrangement of the connecting shaft 6 in the shaft groove 2 provides sufficient space for the rotation and impact movement of the drill bit assembly, ensuring the flexibility and stability of the drill bit body 7 during the drilling process, thereby improving the drilling efficiency and hole-forming quality.

[0047] As Figure 2 can be seen, two mounting pieces 9 are symmetrically and fixedly connected to both sides of the mounting cover 8, through holes are formed through the mounting pieces 9, a plurality of screw holes 10 are symmetrically formed on the outer wall of the sleeve 1, countersunk head screws 11 are arranged in the through holes, and one end of the countersunk head screws 11 passes through the through holes and is rotationally matched with the screw holes 10.

[0048] As can be seen from the above, the mounting cover 8 is matched with the screw holes 10 of the sleeve 1 through the mounting pieces 9 and the countersunk head screws 11 to realize the reliable sealing and fixing of the drill bit mounting hole. This connection method not only has a simple structure and convenient operation, but also can ensure that the drill bit assembly will not loosen or fall off due to vibration or other reasons during the drilling process, thereby ensuring the safety and reliability of the construction.

[0049] As Figures 3 - 4 can be seen, the wire laying assembly includes an inner ring 16 and an outer ring 17 adapted to the inner ring 16. The outer ring 17 is sleeved on the outer wall of the inner ring 16, and a plurality of anchor cable holes 18 and grouting pipe holes 19 are formed through the inner ring 16 and the outer ring 17.

[0050] The outer wall of the outer ring 17 is penetrated with internal threaded holes 20, and the internal threaded holes 20 extend to the outer wall of the inner ring 16;

[0051] Among them, a number of first semi-circular holes for restraining the anchor cable and second semi-circular holes for restraining the grouting pipe are penetrated through the upper wall of the outer ring 17, and a number of third semi-circular holes for restraining the anchor cable and fourth semi-circular holes for restraining the grouting pipe are penetrated through the upper wall of the inner ring 16. When assembling the outer ring 17 and the inner ring 16, the first semi-circular holes and the third semi-circular holes are combined to form the anchor cable holes 18 to erect the anchor cable body 15. Similarly, the second semi-circular holes and the fourth semi-circular holes are combined to form the grouting pipe holes 19 to erect the grouting pipe;

[0052] As can be seen from the above, the cooperative design of the inner ring 16 and the outer ring 17 of the wiring assembly enables the anchor cable body 15 and the grouting pipe to be neatly arranged in the anchor cable holes 18 and the grouting pipe holes 19. By screwing the fixing bolts into the internal threaded holes 20, the outer ring 17 and the inner ring 16 can be tightly fixed together, thereby ensuring that the anchor cable body 15 and the grouting pipe will not be displaced or entangled during the drilling process, improving the construction efficiency and quality, and at the same time facilitating the management and operation of the anchor cable and the grouting pipe by the construction personnel.

Then, the staff fixes the extrusion sleeve 14 to one end of the anchor cable body 15 and fixes the extrusion sleeve 14 in the anchor cable fixing hole, and arranges the grouting pipe between a number of anchor cable bodies 15. After that, the staff erects a number of anchor cable bodies 15 and the grouting pipe through the outer ring 17 and the inner ring 16. When the outer ring 17 is assembled and sleeved on the outer wall of the inner ring 16, a number of fixing bolts are further screwed into the internal threaded holes 20 to fixedly connect the outer ring 17 and the inner ring 16;

[0056] S2. Drilling construction: Connect one end of the impactor 12 to the drill pipe 13 of the drill rig, and further insert the other end of the impactor 12 into the insertion shaft 5 in the drill bit assembly.

When drilling to the designed hole depth, the anchor cable body 15 is also carried to the designed hole depth by the drill bit body 7, completing the installation of the anchor cable. Subsequently, withdraw the drill pipe 13 and the impactor 12. The impactor 12 is separated from the drill bit body 7.
