Description

Technical Field

[0001] The invention relates to the technical field of tunnel construction, and in particular to a tunnel radial drilling trolley and a use method thereof. Background Art

[0002] There are a lot of radial drilling work in the process of tunnel construction and maintenance, such as anchor drilling, drilling to release surrounding rock stress, etc. The existing construction method is mostly to use a hydraulic drill with less than three heads for drilling, and it can only be done in the same square in the tunnel, and the direction of the drill bit entering the hole is perpendicular to the tangent of the tunnel vault. In the prior art, there are two types of tunnel radial drilling construction methods: The first is manual drilling, which requires a dedicated manual operation trolley and a corresponding number of operators, resulting in high labor costs. In addition, manual drilling operations also require corresponding mechanical auxiliary mechanisms (such as manual operation trolleys) for drilling operations at the top of the tunnel. The variable space is small, the operation is complicated, the efficiency is low, and the construction management is difficult. After the construction is completed, the manual operation trolley needs to be moved to carry out subsequent work, which will interfere with other operations in the tunnel at this time. The second type is mechanized construction equipment. In this type of construction method, the construction machinery itself will occupy the central movement line of the tunnel during construction, affecting the construction of other equipment. To achieve simultaneous drilling construction in multiple locations, multiple devices are required to work at the same time. At this time, the equipment cannot be arranged in the narrow tunnel space. In addition, since individual construction equipment has no position positioning with each other, most of the time the drilling position accuracy and spatial angle cannot guarantee the drilling quality.

[0003] If the radial drill is used to quickly release the surrounding rock stress after drilling, the original manual or mechanical construction methods cannot achieve the purpose of quickly releasing the surrounding rock stress through multi-head drilling. Summary of the invention

[0023] See also Figures 1 to 6In order to solve the shortcomings of the prior art that manual or existing mechanical construction methods cannot achieve fast multi-head drilling to release the surrounding rock stress during tunnel construction, the present invention provides a tunnel radial drilling trolley in the first aspect of this embodiment, including a walking mechanism 1, a drilling mechanism 2 and a recovery mechanism 3. Among them, the walking mechanism 1 is used to drive the trolley to move in the tunnel, such as forward, backward, turning and other actions. Two mounting platforms 11 are arranged on the walking mechanism 1. The two mounting platforms 11 are fixedly connected to the walking mechanism 1 and are located on the side of the walking mechanism 1 away from the tunnel surrounding rock. The mounting platform 11 is used to install the recovery mechanism 3. The drilling mechanism 2 is arranged on the walking mechanism 1 and is used to perform drilling operations on the tunnel surrounding rock. The recovery mechanism 3 is arranged on the two mounting platforms 11 and is adapted to the drilling mechanism 2. The recovery mechanism 3 is used to collect sand and stone fragments dropped after the drilling mechanism 2 drills holes in the tunnel surrounding rock.

[0024] Specifically, the drilling mechanism 2 includes two support rails 21 and at least one drilling assembly 22. The two support rails 21 are both arched structures to adapt to the shape of the tunnel. The two rails are respectively arranged at the two ends of the walking mechanism 1. The two support rails 21 are fixedly connected to the walking mechanism 1 and are arranged vertically along the length direction of the walking mechanism 1, that is, when the walking mechanism 1 drives the support rails 21 to move, the two support rails 21 move in a manner parallel to the transverse direction of the tunnel surrounding rock. The two support rails 21 are I-shaped structures, usually composed of two upper and lower horizontal beams and a web connecting the two horizontal beams to form a groove-shaped structure on both sides. This structure enables the rail to have a higher load-bearing capacity and rigidity, and is suitable for occasions that need to bear a large load. The drilling assembly 22 is arranged between the two support rails 21, and the drilling assembly 22 is movably connected to the two support rails 21, so that the drilling assembly 22 moves along the path of the support rails 21 to drill holes at different points of the tunnel surrounding rock. In this embodiment, the traveling mechanism 1 drives the drilling mechanism 2 to move, and holes are drilled at different points in the radial direction of the tunnel surrounding rock. When the traveling mechanism 1 stops, the drilling assembly 22 moves along the path of the two supporting guide rails 21, and holes are drilled at different points in the cross-sectional direction of the tunnel surrounding rock. This solves the technical shortcoming of being unable to achieve rapid multi-head drilling to release surrounding rock stress during tunnel construction, and achieves the technical effect of accurate and efficient drilling at multiple points of the tunnel surrounding rock.

[0025] See also Fig.10As shown, in this embodiment, the number of the drilling assemblies 22 is not limited, but is at least one. For example, the number of the drilling assemblies 22 is two. Based on the positions of the two drilling assemblies 22 moving on the support rail 21, the drilling point range of each drilling assembly 22 on the tunnel surrounding rock is obtained with the support rail 21 as a reference, which is γ≤α+β+γ≤180°, wherein α is the angle at which one drilling assembly 22 moves on the support rail 21, β is the angle at which another drilling assembly 22 moves on the support rail 21, and γ is the angle between the two drilling assemblies 22.

[0026] In this embodiment, for the convenience of describing the drilling assembly 22, one drilling assembly 22 is used for description. The drilling assembly 22 includes a drilling beam 221, two driving modules 222, and a plurality of drilling modules 223. Specifically, the drilling beam 221 is arranged between the two support rails, the drilling beam 221 is in a strip-shaped structure as a whole, and is arranged vertically with the support rails, and the drilling beam 221 is used to provide support for installing the drilling module 223. The two driving modules 222 are respectively arranged on the two support rails 21 and are movably connected to the support rails 21. The two ends of the drilling beam 221 are respectively connected to the two driving modules 222. The two driving modules 222 are used to provide power for the movement of the drilling beam 221, so that the drilling beam 221 moves along the path of the support rails 21 driven by the two driving modules 222. Several of the drilling modules 223 are arranged on the drilling beam 221 and are movably connected to the drilling beam 221. Several of the drilling modules 223 can move along the drilling beam 221. Several of the drilling modules 223 are used to drill holes at different points on the same horizontal line on the tunnel surrounding rock.

[0027] See also Figures 5 and 6 As shown, in this embodiment, each drilling module 223 can be moved individually to adjust the distance between each drilling module 223 to adapt to different drilling requirements. For example, there are 6 drilling modules 223 arranged on the drilling rig beam 221, and the relationship between them is L0=L1+L2+L3+L4+L5, wherein L0 is the maximum stroke of a single drilling module 223 on the beam, and the stroke of L0 is fixed, L1, L2, L3, L4, L5 are the distances between each drilling module 223, and L1 to L5 can be equal or different.

[0028] In this embodiment, in order to facilitate the description of the driving module 222, one driving module 222 is used for description, and the driving module 222 includes a sliding guide sleeve 2221, a gear, a rack 2222 and a power source 2223. Specifically, the sliding guide sleeve 2221 is a sleeve structure with a sliding space inside, and the support rail 21 passes through the sliding space inside the sleeve so that it is sleeved on the support rail and is movably connected with the support rail 21, so that the sliding guide sleeve 2221 slides on the support rail 21, and one end of the drilling rig crossbeam 221 is connected to one side of the sliding guide sleeve 2221, that is, the two ends of the drilling rig crossbeam 221 are respectively connected to the sliding guide sleeves 2221 in the two driving modules 222, so that the drilling rig crossbeam 221 moves synchronously with the sliding guide sleeve 2221. The gear is arranged on the side of the sliding guide sleeve 2221 close to the support rail 21, and the gear is connected to the sliding guide sleeve 2221 in rotation, that is, the gear is connected to the sliding guide sleeve 2221 in rotation and is located in the groove of the support rail. The rack 2222 is fixedly arranged on the side of the support rail 21 close to the gear, and the rack 2222 is located in the groove of the support rail. The rack 2222 is an arched structure adapted to the support rail 21, so that the rack 2222 can fit the support rail, and the gear is meshed and connected with the rack 2222, so that the gear can realize the conversion of rotational motion into linear motion through the rack 2222, thereby effectively realizing mechanical transmission. The power source 2223 is fixedly arranged on the sliding guide sleeve 2221, and the power transmission part at the output end thereof is fixedly connected to the gear, so that the power source 2223 can drive the gear to rotate, that is, the gear is driven to rotate by the power source 2223, and under the action of the rack 2222, the sliding guide sleeve 2221 is driven to move on the supporting guide rail 21, so that the drilling rig crossbeam 221 moves on the supporting guide rail 21 with the sliding guide sleeve 2221. The power source 2223 can be other power providing structures such as an electric motor and a hydraulic motor.

[0029] In some preferred embodiments, in order to further increase the drilling angle of the drilling module 223 into the tunnel surrounding rock, a rotator 22211 is also provided on the sliding guide sleeve 2221, and the drilling beam 221 is connected to the output end of the rotator 22211, so that the drilling beam 221 can rotate along its own axis, wherein the rotator 22211 can be a swing cylinder, which is also called a rotary cylinder or a swing cylinder, and is a prior art. For example, the structure of the swing cylinder generally includes a cylinder body, a piston, a sealing assembly and an end cover, wherein the piston can rotate around the center line of the cylinder body, and the working principle is to use the hydraulic oil in the hydraulic system to promote the rotation of the piston rod, so that the drilling beam 221 connected thereto rotates, thereby driving the drilling module 223 on the drilling beam 221 to adjust the angle along the lateral direction of the tunnel surrounding rock, thereby increasing the drilling angle of the drilling module 223 into the tunnel surrounding rock.

[0030] See also Figures 5 and 6 As shown, in this embodiment, in order to facilitate the detailed description of the drilling module 223, a drilling module 223 is used for description, and the drilling module 223 includes a lower base 2231, a propulsion beam 2232, and a drilling body 2233. Specifically, the lower base 2231 is a slide groove structure, that is, the lower base 2231 is a sliding channel in the shape of a groove, which is connected to the drilling beam 221, and the lower base 2231 is vertically arranged with the drilling beam 221 to maintain a vertical state with the tunnel surrounding rock. A push-pull rod is provided in the lower base 2231, and the push-pull rod is a hydraulic telescopic rod. The push beam 2232 is provided on the lower base 2231, and one end of the push-pull rod is fixedly connected to the lower base 2231, and the other end is fixedly connected to the push beam 2232. The push beam 2232 is movably connected to the lower base 2231 through the push-pull rod, so that the push beam 2232 can slide on the base under the extension and contraction of the push-pull rod. The drilling rig body 2233 is an auger drilling rig, which is a prior art. For example, the auger drilling rig is composed of a drill frame, a power head, an auger rod 4 and a drill bit 43, etc., and is used for drilling holes in tunnel surrounding rocks.

In this embodiment, the propulsion beam 2232 slides on the lower base 2231, so that the propulsion beam 2232 extends out of the lower base 2231, and the drilling rig body 2233 moves through the drilling rig base 22331, so that the spiral drill rod 4 of the drilling rig body 2233 further extends out of the propulsion beam 2232, so that the drilling depth of the spiral drill rod 4 into the tunnel surrounding rock is further improved.

[0031] In this embodiment, in order to further increase the drilling angle of the drilling rig body 2233 on the tunnel surrounding rock, the drilling rig module 223 also includes a rotating base 2234, and the rotating base 2234 is located between the lower base 2231 and the drilling rig beam 221.

One end of the rotating base 2234 is connected to the lower base 2231, and the other end is connected to the drilling rig beam 221. The drilling rig body 2233 moves on the drilling rig beam 221 through the rotating base 2234. Specifically, the rotating base 2234 includes a connecting base plate and a rotating shaft. The bottom end of the connecting base plate is movably connected to the drilling rig beam 221. The connecting base plate is a hydraulic sliding structure, which is a prior art. The hydraulic system arranged thereon is usually equipped with various valves, controllers and other components, which can control the oil flow and direction entering and flowing out of the hydraulic cylinder, so that the rotating base 2234 drives the lower base 2231 to move on the drilling rig beam 221, and then the drilling rig body 2233 moves on the drilling rig beam. The bottom end of the rotating shaft is fixedly connected to the connecting bottom plate, and the top end is fixedly connected to the lower base 2231. The rotating shaft moves on the drilling rig crossbeam 221 through the connecting bottom plate. The rotating shaft is used to drive the lower base 2231 to rotate. For example, the rotating shaft can be a pneumatic dividing plate, an electric dividing plate, or a hollow rotating platform. It is a prior art and will not be described in detail here. It is controlled to rotate by a controller, thereby driving the drilling rig body 2233 to swing at different angles, thereby increasing the radial drilling angle of the drilling rig body 2233 on the tunnel surrounding rock.

[0032] In this embodiment, the walking mechanism 1 includes two load-bearing beams 12, a plurality of driving wheels 13 and a plurality of telescopic legs 14. Specifically, the two support rails 21 are located at both ends of the two load-bearing beams 12, and the support rails 21 are vertically arranged with the load-bearing beams 12, and are used to support the weight of the entire trolley and transmit various forces and moments.

In addition, a universal joint is also provided at one end of the telescopic leg 14 that contacts the ground. By adjusting the universal joint, the telescopic leg 14 fits more closely to the ground and the stability of the trolley is improved.

[0033] In this embodiment, the recovery mechanism 3 includes two collecting components 31, which are respectively arranged on the two mounting platforms 11 and are detachably connected to the mounting platforms 11. The collecting components 31 are used to recover the sand and stone fragments dropped when drilling holes in the tunnel surrounding rock. To facilitate the description of the collecting components 31, one collecting component 31 is used for explanation.

The other end is bent upward to make it higher than the position of the transport conveyor 312 to adapt to the loading position of the transport vehicle cargo box. The lifting conveyor 313 and the transport conveyor 312 work together to transport the sand and stone fragments to the transport vehicle for transfer. Preferably, the transport conveyor 312 and the lifting conveyor 313 are both common conveyor belt structures, which are prior art and are composed of components such as a driving device, a transmission roller and a conveyor belt, and are used to transport items.

[0034] See also Figure 4 As shown, in some preferred embodiments, in order to increase the scope of use of the drilling module 223, for example, when it is necessary to drill the tunnel ground, the receiving module 311 and the load-bearing beam 12 are detachably connected, that is, when drilling the tunnel surrounding rock, the receiving module 311 is installed on the load-bearing beam 12 to receive the sand and stone fragments drilled out of the tunnel surrounding rock. When it is necessary to drill the ground, the rotation space of the drilling module 223 can be reserved, so that the rotation space of the drilling module 223 is larger, and drilling operations are performed on the ground.

[0035] In some preferred embodiments, the recovery mechanism 3 also includes a protective shell 32, which is fixedly arranged on the two mounting platforms 11, and the protective shell 32 is adapted to the support rail 21, that is, the protective shell 32 is composed of a plurality of arch supports and protective plates arranged on the plurality of arch supports, so that the protective shell 32 as a whole presents an arch structure adapted to the support rail 21, so as to leave a central channel to facilitate the normal construction of other tunnels, and a connecting piece is arranged between the support rail 21 and the protective shell 32, and the support rail 21 is fixedly connected to the protective shell 32 through the connecting piece to provide more support points for the support rail 21 and improve the overall structural stability.

[0036] In some preferred embodiments, the transport conveyor 312 is located below the protective shell 32, the transport conveyor 312 is connected to the arch support, and the transport conveyor 312 is located below the protective shell 32, so that sand and gravel fragments from the protective shell 32 can be slid onto the transport conveyor 312 for transfer.

[0037] In some preferred embodiments, a plurality of maintenance ladders are also provided on the protective shell 32. The maintenance ladders are fixedly connected to the protective shell 32 and are located on a side of the protective shell 32 close to the tunnel surrounding rock for workers to climb in order to maintain and replace the equipment.

[0038] In this embodiment, the receiving module 311 includes a bottom plate 3111, a side recovery plate 3112 and a plurality of telescopic support rods 3113. Specifically, the bottom plate 3111 is a flat plate structure, which ensures that the equipment runs stably on a horizontal plane and avoids the tilting problem caused by the uneven bottom plate 3111. It is fixedly arranged on the load-bearing beam 12 and is located between the two guide rails. The bottom plate 3111 is a thick bottom plate 3111, which plays a role in reducing vibration and increasing the installation height of components. The side recovery plate 3112 is arranged on the bottom plate 3111 and is hingedly connected to the bottom plate 3111, so that the side recovery plate 3112 rotates around the hinge between the side recovery plate 3112 and the bottom plate 3111. After receiving the sand and gravel fragments, the side recovery plate 3112 is tilted to make the sand and gravel fragments fall completely onto the transport conveyor 312. One end of the side recovery plate 3112 is located above the transport conveyor 312, so that the side recovery plate 3112 covers the area of ​​the sand and gravel fragments received, thereby preventing the sand and gravel fragments from scattering and improving the collection efficiency of the side recovery plate 3112. A plurality of telescopic support rods 3113 are arranged between the base plate 3111 and the side recovery plate 3112, one end of the telescopic support rod 3113 is hingedly connected to the base plate 3111, and the other end is hingedly connected to the side recovery plate 3112, and the telescopic support rod 3113 is used to drive the side recovery plate 3112 to swing around the hinge between the telescopic support rod 3113 and the base plate 3111. Optionally, the telescopic support rod 3113 is an electric hydraulic telescopic support rod 3113, which is a prior art and includes control elements, hydraulic cylinders, pistons and other components, and can be controlled to extend or contract by a controller. For example, after the side recovery plate 3112 collects sand and gravel fragments, the telescopic support rod 3113 is controlled to extend, so that the side recovery plate 3112 rotates around the hinge between it and the bottom plate 3111, and the side recovery plate 3112 is lifted up. Under the action of gravity, the side recovery plate 3112 slides from one end of the side recovery plate 3112 close to the transport conveyor 312 to the transport conveyor 312, and all the sand and gravel generated by the drilling rig are transported.

[0039] See also Figures 7 and 8As shown, in view of the different hardness of hard rock and soft rock, a spiral drill rod 4 is also provided in the present application to facilitate drilling of soft rock. The spiral drill rod 4 is assembled on the drilling rig body 2233. Specifically, the drill rod includes a center rod 41, a cutting edge 42 and a drill bit 43. Among them, one end of the center rod 41 is provided with a connector for connecting to the rotation source of the drilling rig body 2233. It can be understood that the rotation source is a driving structure in the drilling rig body 2233 for driving the drill rod to rotate. The cutting edge 42 is a spiral structure wound around the center rod 41. When drilling soft rock, the spiral cutting edge 42 can increase the drilling diameter. Among them, the cutting edge 42 can increase or decrease the spiral diameter according to the actual hardness of the soft rock. For example, when the hardness of the soft rock is small, a cutting edge 42 with a larger spiral diameter can be used to increase the cutting area of ​​the rock and improve the drilling efficiency. The drill bit 43 is a conical structure and is disposed on an end of the center rod 41 away from the connector. The design of the conical drill bit 43 makes it easier for its cutting edge to cut into soft rock, thereby increasing the cutting speed for the soft rock.

[0040] As shown in the figure, in some preferred embodiments, in order to further extend the drilling depth, the central rod 41 is divided into a drilling portion 411 and a connecting portion 412. Specifically, the drilling portion 411 is the portion of the central rod 41 connected to the drill bit 43. The end of the drilling portion 411 away from the drill bit 43 is provided with a connecting hole, and the connecting hole is provided with an internal thread. The connecting portion 412 is the portion of the central rod 41 connected to the connector. The end of the connecting portion 412 away from the connector is provided with a connecting column matching the connecting hole. The connecting column is provided with an external thread matching the internal thread. Through the external thread and the internal thread, the connecting column is threadedly connected to the connecting hole, so that the drilling portion 411 is connected to the connecting portion 412. In actual application, different lengths of the drilling portion 411 or the connecting portion 412 can be selected according to different drilling depths to connect the rods, so that the length of the entire central rod 41 is increased or shortened to adapt to different drilling depths.

[0041] See also Fig. 9 As shown, the present invention further provides a method for using a tunnel radial drilling trolley in a second aspect. The method adopts a tunnel radial drilling trolley provided in the first aspect. To facilitate the description of how a tunnel radial drilling trolley performs drilling, a tunnel with a common elliptical cross-section is used as an example. Specifically, the method further includes: S1: According to the number of holes that need to be drilled by multiple drilling heads in the surrounding rock of the tunnel, a corresponding number of the drilling assemblies 22 are installed on the two supporting rails 21; In this step, multiple points of drilling are performed on different axes of the tunnel surrounding rock, and the drilling assemblies 22 corresponding to different axes are installed on the two support rails 21. For example, if it is necessary to drill both sides of the tunnel surrounding rock and the arch at the same time, three drilling assemblies 22 are installed on the support rails 21; S2: Determine the drilling position of the tunnel surrounding rock, and use the travel mechanism 1 to make the trolley move to the corresponding drilling position in the tunnel and stop; In this step, according to the on-site construction arrangement, the trolley is moved to the corresponding drilling position in the tunnel and stops through the traveling mechanism 1, that is, the drilling mechanism 2 and the recovery mechanism 3 are driven to move to the corresponding drilling position through the traveling mechanism 1, and the telescopic legs 14 in the traveling mechanism are extended to lift the trolley to disperse the pressure generated by the trolley during work, reduce the pressure on the ground, and prevent the ground from collapsing or being damaged due to excessive pressure.

[0042] S3: Control the drilling module 223 to move along the path of the support rail 21 under the drive of the driving module 222, control the rotating base 2234 to move on the drilling beam 221, and move the drilling body 2233 in the drilling module 223 to the corresponding drilling position, so that the drilling range of the drilling body 2233 on the tunnel surrounding rock forms an arc surface; By controlling the rotator 22211 to drive the drilling rig crossbeam 221 to rotate, and then controlling the rotation of the rotating base 2234 itself, the drilling angle of the drilling rig body 2233 in the drilling rig module 223 to the tunnel surrounding rock is adjusted; In this step, the drill module 223 rotates the rotating base 2234, thereby causing the drill body 2233 in the drill module 223 to swing along the axial direction of the rotating base 2234 to achieve rotation in one direction, and the drill module 223 rotates the drill beam 221, thereby causing the drill body 2233 in the drill module 223 to rotate in a second direction along the axial direction of the drill beam 221. Since the axial direction of the rotating base 2234 is perpendicular to the axial direction of the drill beam 221, the drill body 2233 can achieve a conical range of drilling angles into the tunnel surrounding rock.

[0043] By controlling the movement of the driving module 222, the drilling rig crossbeam 221 is driven to move along the path of the supporting guide rail 21, thereby driving the several drilling rig modules 223 on the drilling rig crossbeam 221 to move to the corresponding drilling positions. According to the on-site construction requirements, the drilling angles of the tunnel surrounding rock are different. Then, by controlling the rotator 22211, the drilling rig crossbeam 221 is driven to rotate along its own axis, and the orientation of the drilling rig module 223 relative to the tunnel surrounding rock is driven, thereby adjusting the drilling angle of the drilling rig body 2233 in one direction of the drilling rig module 223. Then, by the rotation of the rotating base 2234 in the drilling rig module 223, the drilling angle of the drilling rig body 2233 in the second direction of the drilling rig module 223 is adjusted, so as to realize multi-dimensional drilling of the tunnel surrounding rock to meet the construction requirements. S4: Determine the drilling depth of the tunnel surrounding rock, move the drilling rig body 2233 on the advancing beam 2232, and move the advancing beam 2232 on the lower base 2231, and gradually advance the drilling rig body 2233 to drill the tunnel surrounding rock; In this step, according to the on-site construction requirements, the drilling depth of the tunnel surrounding rock is different, and the drilling rig body 2233 moves on the advancing beam 2232, so that the drill rod is continuously drilled into the tunnel surrounding rock. When the drill rod is insufficient in length, the advancing beam 2232 is controlled to move on the lower base 2231 to increase the drilling depth of the drill rod in the drilling rig body 2233 to meet the construction requirements; S5: controlling the inclination angle of the side recovery plate 3112 in the receiving module 311 through the telescopic support rod 3113 so that the side recovery plate 3112 is located below the drilling position; In this step, the inclination angle of the side recovery plate 3112 is controlled by controlling the extension or shortening of the telescopic support rod 3113. When the telescopic support rod 3113 is shortened, the side recovery plate 3112 rotates toward the side close to the bottom plate 3111, so that the side recovery plate 3112 is located below the drilling position, shielding the space below the drilling position to prevent sand and stone fragments from scattering, thereby collecting the sand and stone fragments on the side recovery plate 1332; S6: The side recovery plate 3112 is tilted again by controlling the telescopic support rod 3113, so that the sand and gravel fragments on the side recovery plate 3112 slide onto the transport conveyor 312, and the sand and gravel fragments on the transport conveyor 312 are transported to the lifting conveyor 313 for transfer.

[0044] In this step, by controlling the extension of the telescopic support rod 3113, the end of the side recovery plate 3112 close to the tunnel surrounding rock is tilted toward the side away from the bottom plate 3111, so that the sand and stone fragments on the side recovery plate 3112 fall onto the transport conveyor 312 due to their own gravity, and then the transport conveyor 312 transports the sand and stone fragments to the lifting conveyor 313, and finally the lifting conveyor 313 transfers the sand and stone fragments.

[0045] This control method can more conveniently control the drilling rig body 2233 to perform multi-point precise drilling on the tunnel surrounding rock to meet on-site construction requirements, quickly release the stress of the tunnel surrounding rock, and collect and transport sand and stone fragments to avoid the falling of sand and stone fragments affecting subsequent construction, thereby improving construction efficiency.

[0046] It should be noted that the above-mentioned usage method is not limited to construction tunnels with elliptical cross-sections, but can also be tunnels with various cross-sectional shapes and sizes, such as tunnels with perfect circular and elliptical cross-sectional shapes, two-lane highway tunnels, four-lane highway tunnels, etc.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
