Abstract
Description
Technical Field
[0001] This utility model belongs to the field of geotechnical engineering technology, specifically relating to an integrated drilling and grouting device. Background Technology
[0002] In existing support construction, traditional tunneling systems typically only have a single drilling rig. Drilling and grouting cannot be carried out simultaneously, resulting in a linear workflow with significant intervals between drilling and grouting. To meet the timeliness requirements of support, additional grouting equipment and teams are often required on-site. This not only disperses equipment resources and occupies already limited construction space but also increases the complexity and coordination difficulties of process connections. It further exacerbates the difficulties in equipment layout, personnel operation, and construction organization within the limited space, ultimately hindering the improvement of overall support efficiency and making it difficult to meet the demands of efficient and continuous construction.
[0003] Therefore, there is an urgent need to provide an integrated device that combines drilling and grouting functions to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a multi-functional integrated device capable of drilling and grouting. This purpose is achieved through the following technical solution:
[0005] The first aspect of this utility model proposes an integrated drilling and grouting device, comprising:
[0006] A drill pipe having a first cavity extending through its axial direction;
[0007] A drilling power head includes a drilling connector and a drilling drive component. The drilling connector is used to connect with the drill pipe, and the drilling drive component is driven to the drilling connector and is used to drive the drilling connector to rotate.
[0008] The grouting power head includes a connecting shaft, a grouting pump, and a grouting connector. The connecting shaft has a second cavity. The inlet end of the connecting shaft is connected to the grouting pump, and the outlet end of the connecting shaft is connected to the grouting connector. The grouting connector is used to connect to the drill pipe, and the first cavity can communicate with the second cavity through the grouting connector. The grouting pump is used to deliver grout to the first cavity.
[0009] This technical solution proposes a composite drilling and grouting integrated device that combines drilling and grouting functions. It highly integrates the two major functional modules of drilling and grouting into a single machine, enabling rapid switching between drilling formation and grout injection. Specifically, its working principle is as follows: During support construction, the drill rod is first connected to the drilling connector. The drilling power head operates, and its drilling drive component drives the drilling connector, causing the hollow drill rod to rotate and perform the drilling task. The first cavity in the center of the drill rod provides a preset channel for subsequent grouting. After drilling to the predetermined depth, the drill rod and drilling power head are separated, and the grouting power head is connected to the drill rod. Grout is pumped in through the second cavity of the connecting shaft. The grout enters the first cavity of the drill rod through the grouting connector and finally overflows from the head of the drill rod, permeating and reinforcing the surrounding soil and rock.
[0010] First, this integrated drilling and grouting equipment allows for the parallel execution of drilling and grouting processes, consolidating what previously required two separate machines and two separate steps into one, significantly improving construction efficiency and shortening the total time for support operations. Second, it effectively reduces labor intensity and safety hazards. Operators no longer need to frequently switch equipment in confined spaces or perform dangerous high-altitude operations; they can complete all operations from a relatively safe location, significantly improving working conditions. Furthermore, replacing the original two sets of equipment (drilling rig and grouting machine) with a single machine reduces the space occupied during construction, simplifies on-site equipment management and scheduling, and facilitates support structure construction in low-ceilinged spaces.

[0038] Figure 1 A schematic diagram of the integrated drilling and grouting equipment according to an embodiment of the present invention is shown. Figure 2 for Figure 1 A magnified view of a portion of point A in the middle. (See image below.) Figure 1 and Figure 2As shown, this utility model proposes an integrated drilling and grouting device, which includes a drill rod 100, a drilling power head 200, and a grouting power head 300. The drill rod 100 has a first cavity extending through its axial direction. The drilling power head 200 includes a drilling connector 210 and a drilling drive 220. The drilling connector 210 is used to connect with the drill rod 100, and the drilling drive 220 is drively connected to the drilling connector 210 and used to drive the drilling connector 210. 0 rotation; the grouting power head 300 includes a connecting shaft 310, a grouting pump 320 and a grouting connector 330. The connecting shaft 310 has a second cavity 311. The inlet end of the connecting shaft 310 is connected to the grouting pump 320, and the outlet end of the connecting shaft 310 is connected to the grouting connector 330. The grouting connector 330 is used to connect with the drill rod 100, and the first cavity can be connected to the second cavity 311 through the grouting connector 330. The grouting pump 320 is used to deliver grout to the first cavity.
[0039] This technical solution proposes a composite device integrating drilling and grouting functions, highly integrating the two major functional modules of drilling and grouting into one device, realizing rapid switching between drilling formation and grout injection. Specifically, its working principle is as follows: During support construction, the drill rod 100 is first connected to the drilling connector 210. The drilling power head 200 operates, and its drilling drive component 220 drives the drilling connector 210 and rotates the hollow drill rod 100 to perform the drilling task. The first cavity in the center of the drill rod 100 provides a preset channel for subsequent grouting. After drilling to the predetermined depth, the drill rod 100 and the drilling power head 200 are separated, and the grouting power head 300 is connected to the drill rod 100. Grout is pumped in through the second cavity 311 of the connecting shaft 310. The grout enters the first cavity of the drill rod 100 through the grouting connector 330 and finally overflows from the head of the drill rod 100, penetrating and reinforcing the surrounding rock and soil.
[0040] First, this integrated drilling and grouting equipment allows for the parallel execution of drilling and grouting processes, consolidating what previously required two separate machines and two separate steps into one, significantly improving construction efficiency and shortening the total time for support operations. Second, it effectively reduces labor intensity and safety hazards. Operators no longer need to frequently switch equipment in confined spaces or perform dangerous high-altitude operations; they can complete all operations from a relatively safe location, significantly improving working conditions. Furthermore, replacing the original two sets of equipment (drilling rig and grouting machine) with a single machine reduces the space occupied during construction, simplifies on-site equipment management and scheduling, and facilitates support structure construction in low-ceilinged spaces.
[0041] Furthermore, the integrated drilling and grouting equipment includes a mobile platform 400, a lifting mechanism 500, and a support platform 700. The lifting mechanism 500 is rotatably connected to the support platform 700. The drilling power head 200 and the grouting power head 300 are both connected to the mobile platform 400. The mobile platform 400 is movably connected to the lifting mechanism 500. The lifting mechanism 500 is used to control the mobile platform 400 to reciprocate along the length direction of the lifting mechanism 500.
[0042] The lifting mechanism 500 is rotatably connected to the support platform 700. This connection allows the lifting mechanism 500 to swing within a certain range to adapt to drilling requirements at different angles and positions. By controlling the stroke of the lifting mechanism 500, the stopping position of the moving platform 400 can be precisely controlled, thereby ultimately determining the height of the drilling power head 200 and the grouting power head 300 on the mounting plate 410. Furthermore, the drilling power head 200 and the grouting power head 300 are arranged side by side along the width direction of the integrated drilling and grouting equipment. After the drilling operation is completed, the integrated drilling and grouting equipment is controlled to move laterally, thereby aligning the grouting power head 300 and the drill rod 100. Optionally, the moving platform 400 includes a mounting plate 410 and a moving plate 420. The drilling power head 200 and the grouting power head 300 are connected to the top of the mounting plate 410, and the mounting plate 410 is connected to the lifting mechanism 500 through the moving plate 420.
[0043] Furthermore, the lifting mechanism 500 includes a transmission chain 510, a drive device, and a frame 520. The drive device includes a fixed end and an output end. The fixed end is connected to the frame 520, and the output end is connected to the transmission chain 510 for driving the transmission chain 510 to rotate. The movable plate 420 is connected to the transmission chain 510.
[0044] Chain drives have extremely high tensile strength and can withstand heavy loads. By cooperating with drive devices (such as servo motors or hydraulic motors with encoders) and setting positioning marks on the drive chain 510 or using high-precision sensors, precise control of the lifting position of the moving platform 400 can be achieved, meeting the positioning accuracy requirements of automated drilling.
[0045] Furthermore, a limit plate 600 is connected to the top of the frame 520. The limit plate 600 is provided with a clearance hole, which is set directly opposite the drilling connector 210 and is used to pass through the drill rod 100.
[0046] During the initial drilling and lowering of the drill rod 100, the clearance hole can serve as a guide channel to help the operator initially align the drill rod 100 with the predetermined drilling position, preventing damage to the drill bit or borehole due to excessive initial deviation.
[0047] Furthermore, the integrated drilling and grouting equipment also includes multiple support structures 800, which are connected to the support platform 700. Each support structure 800 includes liftable outriggers 810, the bottom of which is used to contact the ground.
[0048] Understandably, the outriggers 810 provide stable support for the integrated drilling and grouting equipment, preventing it from moving due to vibration or impact during drilling or grouting. Optionally, four sets of support structures 800 are provided, each located at one of the four corners of the support platform 700. Optionally, the outriggers 810 are hydraulically driven.
[0049] Figure 3 A schematic diagram of the grouting power head 300 according to an embodiment of the present invention is shown. Figure 4 yes Figure 3 A schematic diagram of the cross-section at BB. See also Figure 3 and Figure 4 Furthermore, the grouting power head 300 also includes a grouting drive 340. The cavity wall of the first cavity has an internal thread, and the grouting connector 330 has an external thread. The grouting drive 340 is connected to the connecting shaft 310 and is used to drive the connecting shaft 310 to rotate so that the grouting connector 330 is connected to the drill rod 100 through the external and internal threads.
[0050] In this embodiment, when connecting the grouting power head 300 and the drill rod 100, the grouting connector 330 is aligned with the first cavity of the drill rod 100. The grouting drive 340 controls the grouting connector 330 to rotate in reverse, causing the external thread of the grouting connector 330 to screw into the first cavity and connect with the internal thread on the cavity wall. When separating the grouting power head 300 and the drill rod 100, the grouting drive 340 controls the grouting connector 330 to rotate forward, causing the external thread of the grouting connector 330 to unscrew from the first cavity, thereby removing the drill rod 100. This connection method between the grouting power head 300 and the drill rod 100 allows for a simple and efficient loading and unloading process, which helps to speed up the overall operation. Furthermore, the connection is stable and reliable, ensuring that the grout can smoothly enter the first cavity from the second cavity 311, reducing the occurrence of leakage or jamming. Optionally, the grouting power head 300 can be a hydraulic motor or an electric motor.
[0051] Optionally, in some embodiments, two second cavities 311 can be provided, each independently configured to store different grouts. These grouts are pumped by a grouting pump 320, mixed at the front end of the grouting connector 330, and then injected into the first cavity of the drill pipe 100, thereby achieving dual-liquid grouting. In the case of dual-liquid grouting, the grouting pump 320 can be a dual-cylinder pump or a dual-liquid grouting machine, with the two grouts being delivered synchronously according to a preset ratio.
[0052] Furthermore, the grouting power head 300 also includes a grouting output shaft (not shown in the figure), the output end of the grouting drive 340 is connected to the grouting output shaft, and the grouting output shaft and the connecting shaft 310 are driven by gear meshing.
[0053] With this structural design, the grouting drive unit 340 can focus on providing efficient rotational power, while the gear transmission system undertakes the tasks of torque amplification, speed change, and reversal, resulting in a more rational overall power matching and more efficient system operation. This structure can effectively transmit the rotational power of the grouting drive unit 340 to the connecting shaft 310, reducing power loss and ensuring that the connecting shaft 310 and the drill rod 100 obtain stable and sufficient torque to overcome the resistance during the grouting process (such as the viscous resistance of the grout), ensuring the continuity and uniformity of the grouting process, and thus improving the grouting quality.
[0054] Furthermore, there are two grouting drive units 340, each of which is connected to a grouting output shaft, and the two grouting output shafts are located on both sides of the connecting shaft 310.
[0055] In this embodiment, the grouting power head 300 uses a dual-drive structure. During normal grouting, both drives are used simultaneously to achieve efficient connection between the grouting connector 330 and the drill rod 100. When disassembling the drill rod 100, it switches to single-drive operation to achieve low-speed, high-torque operation, ensuring smooth disassembly of the drill rod 100. In extreme cases, even if one drive fails unexpectedly, the other drive can still maintain the grouting power head 300 to continue working at reduced power instead of completely stopping, thereby improving the continuity and reliability of the overall operation and reducing construction interruptions and quality risks caused by sudden equipment failures.
[0056] Figure 5 A schematic diagram of the structure of a drilling power head 200 according to an embodiment of the present invention is shown. Figure 6 yes Figure 5 A schematic diagram of the cross-section at point AA. See also... Figure 5 and Figure 6 The drilling connector 210 also has external threads. The grouting connector 330 is rotated by the drilling drive 220, thus connecting the drilling connector 210 and the drill rod 100. Specifically, when connecting the drilling power head 200 and the drill rod 100, the drilling connector 210 is aligned with the first cavity of the drill rod 100. The drilling drive 220 controls the drilling connector 210 to rotate in reverse, causing the external thread of the drilling connector 210 to screw into the first cavity and connect with the internal threads on the cavity wall. When separating the drilling power head 200 and the drill rod 100, the drilling drive 220 controls the drilling connector 210 to rotate forward, causing the external thread of the drilling connector 210 to unscrew from the first cavity.
[0057] Furthermore, the drilling power head 200 also includes a drilling output shaft (not shown in the figure) and an intermediate shaft 230. The output end of the drilling drive 220 is connected to the drilling output shaft. The drilling output shaft and the intermediate shaft 230 are driven by gear meshing. The drilling connector 210 is connected to the intermediate shaft 230.
[0058] This configuration achieves efficient and stable power transmission through gear meshing. The drilling drive unit 220 can focus on outputting optimal speed and power, while the gear transmission system undertakes the tasks of torque amplification and speed change, making the power output more compatible with the drilling load requirements. Secondly, the high rigidity and precision of the gear transmission ensure that the drilling connector 210 and drill rod 100 receive smooth and strong rotational torque, effectively reducing vibration and slippage, and improving drilling efficiency and quality. Finally, this structure enhances the system's load-bearing capacity and durability, can adapt to impact loads in complex formations, and has a compact layout that facilitates maintenance, thus improving the overall reliability and adaptability of drilling.
[0059] Furthermore, there are two drilling drive units 220, each of which is connected to a drilling output shaft, and the two drilling output shafts are located on both sides of the intermediate shaft 230.
[0060] In this embodiment, the drilling power head 200 uses a dual-drive structure. During normal drilling, both drives are used simultaneously to achieve efficient drilling and rapid slag removal. When disassembling the drill rod 100, it switches to single-drive operation to achieve low-speed, high-torque operation, ensuring smooth disassembly of the drill rod 100. In extreme cases, even if one drive fails unexpectedly, the other drive can still maintain the drilling power head 200 to continue operating at reduced power instead of completely stopping, thereby improving the continuity and reliability of the overall operation and reducing construction interruptions and quality risks caused by sudden equipment failures.
[0061] Optionally, the integrated drilling and grouting equipment is equipped with a control assembly. Both the drilling drive unit 220 and the grouting drive unit 340 are electrically connected to the control assembly to control the drilling and grouting processes. The configuration and control method of the control assembly are mature existing technologies in this field and will not be described in detail here.
[0062] The process of constructing a support structure using the integrated drilling and grouting equipment provided in this technical solution mainly includes the following steps:
[0063] S1. Measurement and layout: Measure and layout according to the spacing, row spacing and elevation provided in the design.
[0064] S2. Equipment positioning: The drilling and grouting integrated equipment is moved to the designated position by the control assembly, and the outriggers 810 located around the support platform 700 are extended to stabilize the drilling and grouting integrated equipment.
[0065] S3. Drilling: After the integrated drilling and grouting equipment is in place, align the drill rod 100 with the drilling connector 210. Control the drilling drive 220 through the control assembly to drive the drilling connector 210 to rotate in reverse and screw into the drill rod 100, completing the threaded connection. After the connection is completed, adjust the drilling connector 210, the drill rod 100, and the center of the hole to coincide. After ensuring that the verticality of the drill rod 100 meets the requirements, start the drilling drive 220 to drill. Stop drilling after reaching the designed depth. After stopping drilling, control the drilling drive 220 through the control assembly to drive the drilling connector 210 to rotate forward, completing the separation of the drilling connector 210 and the drill rod 100. Then, manually pull out the drill rod 100 to complete the disassembly of the drill rod 100.
[0066] S4. Grouting: The control assembly controls the movement of the integrated drilling and grouting equipment to align the grouting connector 330 and the drill rod 100. The control assembly is then manipulated to reverse the grouting drive component 340, thereby connecting the grouting connector 330 and the drill rod 100 via threads. After the connection is completed, the grouting pump 320 is started to perform grouting.
[0067] S5. After grouting is completed, control the moving plate 420 to move upward along the frame 520, thereby lifting the drill rod 100. Control the grouting drive component 340 through the control assembly to drive the grouting connector 330 to rotate forward, so that the drill rod 100 is separated from the grouting connector 330. Then, manually pull out the drill rod 100 to complete the disassembly of the drill rod 100.
[0068] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
