Description

A drilling sealing device and sealing method Technical Field

[0001] This invention relates to the field of geological exploration equipment technology, specifically to a drilling sealing device and sealing method. Background Technology

[0002] Geological exploration is the investigation and research activity that uses various means and methods to explore and detect geology, determine suitable bearing strata, determine the foundation type based on the bearing capacity of the bearing strata, and calculate foundation parameters. It involves investigating and researching the geological conditions of a specific area, including rocks, strata, structures, minerals, hydrology, and geomorphology, to ascertain the quality and quantity of minerals, as well as the technical conditions for mining and utilization, and to provide the necessary mineral reserves and geological data for mine construction design.

[0003] Currently, many engineering standards in China have corresponding requirements for borehole sealing technology. For example, the "Technical Specification for Geological Exploration and Sampling of Building Engineering" (JGJ / T87-2012) and the "Specification for Geotechnical Engineering Investigation of Tianjin Rail Transit" (DB / T29-253-2018) both require borehole sealing and backfilling after the exploration work is completed. However, borehole sealing and backfilling construction not only requires strict control of the weight ratio of the backfill material, but also requires mixing and other processes. Some borehole sealing methods (such as the sealing method) also require compaction during construction. The entire borehole sealing process is complex, and the weight ratio is difficult to control precisely, resulting in poor borehole sealing and backfilling quality and low efficiency. Summary of the Invention

[0004] To address the problems of complex procedures and difficulty in precisely controlling weight ratios in existing hole sealing processes, resulting in poor backfill quality and low efficiency, this invention provides a drilling hole sealing device, comprising:

[0005] Sealing control platform;

[0006] A backfill assembly is installed on the bottom surface of the sealing control platform. The backfill assembly is used to store or transport backfill material, and the backfill assembly is movable relative to the sealing control platform.

[0007] A weighing assembly is assembled on the sealing control platform, and a conveying assembly is provided on the weighing assembly. The conveying assembly is used to convey backfill material to the weighing assembly and to convey the backfill material in the weighing assembly to the backfilling assembly.

[0008] A sealing assembly is mounted on the top surface of the sealing control platform. The sealing assembly passes through the sealing control platform at least partially and extends into the backfill assembly to perform a mixing action.

[0009] In some embodiments, the sealing assembly includes:

[0010] A penetration box is assembled on the top surface of the sealing control platform, and the penetration box is provided with through holes;

[0011] A connecting rod is inserted into the through hole of the penetration box, and the bottom end of the connecting rod passes through the sealing control platform. The bottom end of the connecting rod is used to assemble a compaction head or a stirring head.

[0012] A rotating chuck is mounted on the top surface of the penetration box. The rotating chuck is used to engage with the connecting rod and drive the connecting rod to rotate.

[0013] In some embodiments, the sealing assembly further includes a lifting unit, which includes a first conveyor chain and a telescopic member. The first conveyor chain is installed inside the penetration box, and the telescopic member is connected to the first conveyor chain. The telescopic member engages with the connecting rod inside the through hole, and the first conveyor chain can drive the telescopic member to move so that the connecting rod moves along the length direction of the through hole.

[0014] In some embodiments, the lifting unit can drive the connecting rod equipped with the compaction head to extend into the borehole and compact the bottom of the borehole.

[0015] In some embodiments, the connecting rod includes at least two single rods, the ends of which are detachably connected.

[0016] In some embodiments, the backfill component includes:

[0017] A transmission unit is assembled on the bottom surface of the sealing control platform. The transmission unit is equipped with a funnel and is used to drive the funnel to move horizontally or vertically below the sealing control platform.

[0018] A conduit is disposed on the funnel and connected to the bottom opening of the funnel, and a sealing plate is provided inside the conduit.

[0019] In some embodiments, the conveying assembly includes:

[0020] A first conveyor belt, one end of which is connected to the weighing component, and the other end of which is provided with a digging shovel;

[0021] The second conveyor belt has one end connected to the weighing component and the other end used to dock with the backfilling component.

[0022] In some embodiments, the sealing control platform is equipped with tracks at its bottom.

[0023] In some embodiments, the sealing control platform is provided with multiple movable support rods, which have extended and retracted states. When the movable support rod is in the retracted state, the sealing control platform is supported on the bottom surface by the tracks. When the movable support rod is in the extended state, the movable support rod is supported on the ground, and the sealing control platform is supported on the movable support rod.

[0024] On the other hand, this application provides a sealing method using the above-mentioned drilling sealing equipment, which includes the following steps:

[0025] The sealing control platform is placed above the borehole, and the backfill assembly is aligned with the borehole.

[0026] The backfill material is conveyed to the weighing assembly through the conveying assembly, and the weight ratio of the backfill material is determined by the weighing assembly.

[0028] The sealing assembly is controlled to agitate the backfill material in the backfill assembly;

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Addressing the problems of complex procedures and difficulty in precisely controlling weight ratios in the existing sealing process, resulting in poor sealing and backfill quality and low efficiency, as shown in Figures 1 and 2, the present invention provides a drilling sealing device, comprising: a sealing control platform 1, a backfilling component 2, a weighing component 3, and a sealing component 5; wherein,

[0041] A backfill assembly 2 is assembled on the bottom surface of the sealing control platform 1. The backfill assembly 2 is used to store or transport backfill material, and it is movable relative to the sealing control platform 1. A weighing assembly 3 is assembled on the sealing control platform 1, and a conveying assembly 4 is provided on the weighing assembly 3. The conveying assembly 4 is used to transport backfill material to the weighing assembly 3, or to transport backfill material from the weighing assembly 3 to the backfill assembly 2. A sealing assembly 5 is assembled on the top surface of the sealing control platform 1. The sealing assembly 5 at least partially passes through the sealing control platform 1, extends into the backfill assembly 2 to perform a stirring action, and extends into the borehole 6 to compact the bottom of the borehole 6. Optionally, the weighing assembly 3 includes an electronic scale for weighing the fill material.

[0042] It should be noted that substandard borehole sealing quality can lead to the following hazards: 1. Contaminated surface water can easily enter groundwater bodies, causing groundwater pollution. 2. In some geological conditions with confined water, poorly sealed boreholes may form hydraulic channels, inducing engineering accidents such as sudden surges. 3. In shield tunnel projects, it may cause grout leakage during synchronous or secondary grouting, or loss of shield pressure control. 4. In drill-and-blast tunnel projects in mountainous areas, the shock wave generated by drilling and blasting can cause instability at the tunnel face and form water inflow channels, increasing construction difficulties and affecting construction quality. 5. For projects involving water conservancy and river embankments, it may lead to piping, which can cause dam failure under long-term hydraulic action. Therefore, borehole sealing, as one of the most important aspects of drilling engineering quality, deserves attention and importance. One of the key factors affecting sealing quality is the weight ratio of the components of the sealing material. In this application, the sealing control platform 1 is equipped with a weighing component 3. The weighing component 3 can directly weigh and record the sealing material, and can accurately measure the amount of cement mortar and the required amount of clay balls. All of these materials are then filled into the hole through the conveying component 4 and the backfilling component 2, saving materials and achieving optimal sealing.

[0043] Preferably, the power systems of all modules of the drilling and sealing equipment are located below the sealing control platform 1, and the entire device is powered by a battery pack. The sealing control platform 1 has a circular hole for alignment with the borehole, through which the sealing assembly 5 passes. The diameter of the circular hole is larger than the diameter of the borehole but smaller than the diameter of the supporting part of the backfill assembly 2 below. A rectangular hole is also provided inside the location of the weighing assembly 3 for the transfer of raw materials.

[0044] In some specific embodiments, the sealing assembly 5 includes: a penetration box 51, a connecting rod 52, and a rotating chuck 53; wherein,

[0045] A penetration chamber 51 is assembled on the top surface of the sealing control platform 1, and a through hole 511 is provided inside the penetration chamber 51. A connecting rod 52 passes through the through hole 511 of the penetration chamber 51, and the bottom end of the connecting rod 52 passes through the sealing control platform 1. The bottom end of the connecting rod 52 is used to assemble a compaction head 521 or a stirring head 522. A rotary chuck 53 is assembled on the top surface of the penetration chamber 51. The rotary chuck 53 is used to engage with the connecting rod 52 and drive the connecting rod 52 to rotate.

[0046] Optionally, the connecting rod 52 may also be equipped with a counterweight to work with the connecting rod to compact the sealing material inside the hole and mix the cement mortar.

[0047] Understandably, the sealing assembly 5 has two functions: first, to mix the sealing material prepared by the counterweight in the backfill assembly 2; and second, to compact the drilled hole. Operators can achieve different functions by disassembling and replacing the end of the connecting rod 52.

[0048] Optionally, the rotary chuck 53 can be an electronic three-jaw chuck, which can fix the connecting rod 52 and control the rotation of the connecting rod 52 to complete the stirring function.

[0049] Furthermore, the sealing assembly 5 also includes a lifting unit 54, which includes a first conveyor chain 541 and a telescopic device 542; wherein,

[0050] The first conveyor chain 541 is installed inside the penetration box 51. The telescopic device 542 is connected to the first conveyor chain 541. The telescopic device 542 is engaged with the connecting rod 52 in the through hole 511. The first conveyor chain 541 can drive the telescopic device 542 to move so that the connecting rod 52 moves along the length direction of the through hole 511.

[0051] Specifically, a first conveyor chain 541, inserted into the box 51, is installed on both sides of the connecting rod 52, and the first conveyor chains 541 on both sides rotate synchronously. Each side is equipped with an expansion joint 542, which can be used to engage with the connecting rod 52 and drive it to move with the first conveyor chain 541. The first conveyor chain 541 is powered by a motor, which can control its forward and reverse rotation, providing power for lowering the connecting rod 52 into the borehole 6 and performing compaction and tamping actions.

[0052] Preferably, as shown in Figures 4 and 5, the connecting rod 52 includes at least two single rods 523, the ends of which are detachably connected.

[0053] Optionally, one end of a single rod 523 is provided with an internal thread and the other end is provided with an external thread, and two single rods 523 can be threaded together as one unit.

[0054] Understandably, for ease of transportation and use, the connecting rod 52 adopts a multi-segment splicing design. In specific use, firstly, a single rod 523 is fully inserted into the insertion box 51 and fixedly clamped with the expansion joint 542. Then, a second single rod 523 is fully inserted into the insertion box 51 and connected with the first single rod 523. Finally, the rotating chuck 53 is used to twist the second single rod 523 to tighten both single rods 523.

[0055] Preferably, as shown in Figure 6, the telescopic device 542 includes a spring 543 and a telescopic rod 544. The power system can drive the telescopic rods 544 on both sides to clamp the connecting rod 52 through the spring 543. Of course, the telescopic device 542 can also adopt other structural forms to achieve the snap-fit ​​function.

[0056] In some specific embodiments, as shown in FIG3, the backfill assembly 2 includes: a transmission part 21, a funnel 22, and a conduit 23; wherein,

[0057] A transmission unit 21 is mounted on the bottom surface of the sealing control platform 1. A funnel 22 is mounted on the transmission unit 21, and the transmission unit 21 is used to drive the funnel 22 to move horizontally or vertically below the sealing control platform 1. A guide tube 23 is mounted on the funnel 22 and connected to the bottom opening of the funnel 22. A sealing plate 24 is provided inside the guide tube 23.

[0058] Optionally, a closing plate 24 is movably installed in the funnel 22, allowing the operator to open or close the opening of the funnel 22 by operating the closing plate 24. The guide tube 23 is a flexible hose used to inject cement mortar into a designated location within the hole. The drive unit 21 can be a conveyor belt, driving the funnel 22 to move and align it with the borehole.

[0059] In some preferred embodiments, the conveying assembly 4 includes: a first conveyor belt 41 and a second conveyor belt 42; wherein,

[0060] One end of the first conveyor belt 41 is connected to the weighing component 3, and the other end is provided with a digging shovel part 43. One end of the second conveyor belt 42 is connected to the weighing component 3, and the other end is used to dock with the backfilling component 2.

[0061] It is worth noting that both the output and input backfill material of the weighing assembly 3 are conveyed by the conveying assembly 4. The excavator 43 is connected to the power system signal.

[0062] Preferably, to facilitate the movement of the sealing control platform 1, the bottom of the sealing control platform 1 is provided with tracks 11. The tracks 11 are also driven and controlled by the power system, and the operator can adjust the position of the sealing control platform 1 to align with the borehole as needed.

[0063] In some preferred embodiments, as shown in FIG1, the sealing control platform 1 is provided with a plurality of movable support rods 12. The movable support rods 12 include an extended state and a retracted state. When the movable support rods 12 are in the retracted state, the sealing control platform 1 is supported on the bottom surface by the track 11. When the movable support rods 12 are in the extended state, the movable support rods 12 are supported on the ground, and the sealing control platform 1 is supported on the movable support rods 12.

[0064] Preferably, in order to better support and improve the stability of the sealing construction, the sealing control platform 1 is roughly rectangular, with a movable support rod 12 near each of the four corners of its bottom.

[0065] In some specific embodiments, the sealing control platform 1 is equipped with a control panel 7, which is signal-connected to the backfill component 2, the weighing component 3, and the sealing component 5. The control panel 7 drives the aforementioned components to perform their respective actions via a power system.

[0066] It is understandable that the power system and the control of each component module in this application are all electronically controlled, which has less noise and less negative impact on the environment compared to other drive methods.

[0067] Furthermore, as shown in Figure 1, the control panel 7 is located on the top surface of the sealing control platform 1. The sealing control platform 1 is also equipped with a seat for the operator to sit on, so as to facilitate the operation of various components through the control panel 7 in real time. As shown in Figure 2, the battery pack of the power system is also located on the bottom surface of the sealing control platform 1.

[0068] On the other hand, this application also provides a sealing method using the above-mentioned drilling sealing equipment, which includes the following steps:

[0069] S1. Place the sealing control platform above the borehole 6 and control the backfilling component 2 to align with the borehole 6.

[0070] Specifically, after the drilling rig completes drilling and coring and moves, the sealing control platform 1 enters the site to position and seal the borehole. When the sealing control platform 1 moves to the vicinity of the borehole position via motor drive, it tries to align the hole in the middle of the sealing control platform 1 (the hole through which the sealing assembly 5 passes) with the drilling borehole position. Then, the transmission unit 21 is operated by the control panel 7 to move the funnel 22 in the horizontal and vertical directions, ensuring that the guide tube 23 is lowered into the borehole and that the funnel 22 is positioned exactly at the borehole opening.

[0071] Subsequently, the movable support rods 12 at the four corners of the sealing platform are activated to support the entire platform and ensure its stability.

[0072] S2. The backfill material is conveyed to the weighing component 3 through the conveying component 4, and the weight ratio of the backfill material is adjusted using the weighing component 3.

[0073] Specifically, before weighing, ensure that the sealing plate 24 is open and filled with clean water. After confirming that the conduit 23 is unobstructed, close the sealing plate 24 of the funnel. Then, turn on the electronic scale of the weighing component 3 through the control panel 7, operate the digging shovel 43 to shovel the nearby sealing materials cement and sand onto the first conveyor belt 41, and transfer them to the weighing component 3 for weighing. The weighing value is calculated based on the mix ratio.

[0074] S3. The backfill material after proportioning in the weighing component 3 is conveyed to the backfill component 2 through the conveying component 4.

[0075] Specifically, the cement and sand obtained from the final weighing are mixed into the funnel 22 as backfill material via the second conveyor belt 42.

[0076] S3. Control the sealing assembly 5 to stir the backfill material in the backfill assembly 2.

[0077] Specifically, after adding an appropriate amount of water to the funnel 22, the infeed box 51 is moved to the middle position via the slide rail and fixed. Then, the stirring head 522 and the connecting rod 52 are connected and passed through the hole in the infeed box 51 above. The control panel 7 is operated to control the telescopic device 542 to lock the first single rod 523. Then, the second single rod 523 is placed in and locked by the electronic three-jaw chuck of the rotating chuck 53. After rotation, it is tightened with the first single rod 523. Then, the first conveyor chain 541 is rotated to lower the connecting rod 52. The stirring head 522 is lowered into the funnel 22 in this way. The electronic three-jaw chuck is rotated again to drive the connecting rod 52 to rotate to complete the stirring work.

[0078] S4. Control the backfilling assembly 2 to deliver backfill material to the borehole 6.

[0079] In some specific embodiments, after the mixing is completed, the funnel 22 is moved up and down again so that the guide tube 23 is placed 0.3 to 0.5 m from the bottom of the hole. The sealing plate 24 is opened and cement mortar is poured down. When the sealing section is less than 2.0 m, the guide tube 23 is not raised arbitrarily during the cement mortar conveying process. When the sealing section is greater than 2.0 m, the guide tube 23 should be raised through the transmission part 21 while the cement mortar is being poured. The guide tube 23 should not be raised above the surface of the cement mortar.

[0080] S5. Control the sealing assembly 5 to compact the drilled hole 6.

[0081] It should be noted that when using the clay ball sealing method, the thick mud in the hole must be replaced with clean water beforehand until the clay balls can sink smoothly to the predetermined position. When filling the clay balls, the amount of clay balls to be used must be determined in advance based on the thickness of a single layer of sealing, and then weighed using the weighing component 3 before being put into the hole.

[0082] Furthermore, after the corresponding clay balls are inserted, the compaction head 521, counterweight, and connecting rod 52 are connected and passed through the upper penetration hole. The control panel 7 is then operated to assemble the connecting rod 52. The conveyor chain is then rotated to lower the connecting rod 52, creating downward pressure that pushes the clay balls to the bottom, thus completing the compaction process. After multiple injections of cement mortar and compaction of the clay balls, the sealing of one borehole is finally completed. The sealing equipment is then moved to seal the next borehole.

[0083] In summary, this application integrates the weighing and sealing backfilling components, which not only facilitates operation but also improves efficiency. The weighing device can directly weigh and record the sealing materials, accurately measure the amount of cement mortar and required clay balls, and fill them all into the holes via conveyor belt and funnel, saving consumables and achieving optimal sealing. Therefore, this invention has the advantages of electronic installation of connecting rods, automated compaction, precise sealing, and integrated operation.
