Description

Technical Field

[0001] The present invention relates to the technical field of mining operations, and in particular to a device and method for drilling hole water sealing. Background Art

[0002] In soft rock tunnels, drill holes are inevitably drilled for various purposes. These holes are used to observe the lithology or to seal cracks with grouting. However, when the drill holes penetrate the surrounding rock aquifers, water flows into the tunnel through the drill holes. This water not only reacts with the surrounding rock to form mud, causing severe deformation and damage, but also significantly increases drainage work within the tunnel, seriously affecting efficient and safe production.

[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0025] The following describes a borehole water sealing device 100 according to an embodiment of the present invention with reference to the accompanying drawings.

[0026] like Figure 1 As shown, a device 100 for water sealing a borehole according to an embodiment of the present invention includes a sealing member 1 , a connecting member 2 and an inflatable member 3 .

[0027] The sealing member 1 is suitable for being arranged in a borehole and comprises an inflatable portion 11 and an expansion portion 12. The inflatable portion 11 is used for expanding with air to seal the borehole, and the expansion portion 12 is used for absorbing the liquid in the borehole to expand the expansion portion 12. Specifically, as Figure 1 As shown, the sealing member 1 can be set in the drilled hole of the tunnel, and the expansion part 12 is set on the outer peripheral surface of the inflatable part 11. Gas can be introduced into the inflatable part 11 to expand the inflatable part 11. The expansion part 12 can absorb the liquid (for example, water) in the tunnel and expand, so that the sealing member 1 can seal the drilled hole.

[0028] The connecting member 2 has an air filling hole running through the connecting member 2, the connecting member 2 is detachably connected to the sealing member 1, and the air filling hole is communicated with the air filling portion 11 so that the connecting member 2 can fill the air filling portion 11. Specifically, Figure 1 As shown, the connecting member 2 can be a connecting rod 21 and an inflation hole is provided on the connecting member 2 which passes through the connecting member 2. The outlet of the inflation hole is connected to the inlet of the inflatable member 3, so that the connecting member 2 inflates the inflatable part 11, causing the inflatable part 11 to expand, thereby driving the outer peripheral surface of the expansion part 12 to contact the inner peripheral surface of the drilled hole.

[0029] The inflatable member 3 is provided at one end of the connecting member 2 away from the sealing member 1 and is connected to the inflatable portion 11 through the inflatable hole, so that the inflatable member 3 inflates the inflatable portion 11 through the connecting member 2. Specifically, Figure 1As shown, the inflatable member 3 is provided at the other end of the connecting member 2 and is communicated with the inflatable portion 11 through the inflatable hole, so that the inflatable member 3 inflates the inflatable portion 11 .

[0030] The device 100 for water sealing a borehole in an embodiment of the present invention is provided with a sealing member 1, and gas can be introduced into the inflatable portion 11 for expansion, so that the inflatable portion 11 fills the tunnel to form a preliminary seal, and the expansion portion 12 absorbs water in the borehole and expands, so that the expansion portion 12 seals the borehole to form a secondary seal, thereby overcoming the problems of consuming manpower and material resources and having poor water sealing effects when dealing with water sealing problems in boreholes in soft rock tunnels in related technologies, thereby affecting safe and efficient production in the tunnel, improving the efficiency and safety of water sealing in boreholes in soft rock tunnels, and saving time and effort.

[0031] In some embodiments, the connecting member 2 includes a plurality of connecting rods 21, which are detachably connected in sequence. The connecting rods 21 are provided with a plurality of connecting rods 21 along their length direction (such as Figure 1 The plurality of through holes are connected in sequence to define the air filling hole. Figure 1 As shown, the connecting rod 21 is a vertical rod of high-strength aluminum alloy extending in the up-down direction. The connecting rod 21 is provided with a through hole passing through the connecting rod 21 in the up-down direction. A plurality of connecting rods 21 are detachably connected in sequence. According to the location and depth of the water leakage in the drilled hole, the connecting rod 21 is installed or removed to extend or shorten the connecting member 2, so that the connecting member 2 drives the sealing member 1 to the designated sealing position.

[0032] In some embodiments, the outer circumference of one end of the connecting rod 21 is provided with an external thread, and the inner circumference of the other end of the connecting rod 21 is provided with an internal thread, and two adjacent connecting rods 21 are threadedly matched with the internal thread and the external thread so that the two adjacent connecting rods 21 are detachably connected. Specifically, Figure 1 As shown, the upper end of the connecting rod 21 is provided with a first connecting portion, the outer peripheral surface of the first connecting portion is provided with an external thread, the lower end of the connecting rod 21 is provided with a second connecting portion, the second connecting portion is provided with a threaded hole passing through the second connecting portion in the up and down directions, the threaded hole is connected with the through hole of the connecting rod 21, the first connecting portion of the connecting rod 21 is passed through the threaded hole of the second connecting portion, the external thread of the first connecting portion and the threaded hole of the second connecting portion are threadedly connected, so that the two adjacent connecting rods 21 can be detachably connected.

[0033] In some embodiments, the inflatable portion 11 is a balloon rod with a valve needle joint. Thus, the inflatable portion 11 is expanded in the drilled hole and the balloon rod is prevented from leaking by the valve needle, thereby making the inflatable portion 11 more reasonably arranged.

[0034] In some embodiments, the inflatable member 3 includes an inflatable tube 31 and an inflatable pump 32. The inflatable tube 31 is provided in the inflatable hole and both ends of the inflatable tube 31 are connected to the inflatable portion 11 and the inflatable pump 32, respectively, so that the inflatable pump 32 inflates the inflatable portion 11 through the inflatable tube 31. Specifically, Figure 1 As shown, the inflation tube 31 is an inflation hose, which is passed through the inflation hole, and the two ends of the inflation tube 31 are respectively connected to the joints of the inflation pump 32 and the valve needle of the inflation part 11, so that the inflation part 11 is inflated through the inflation pump 32.

[0035] In some embodiments, the expansion portion 12 includes an expansion bag and an expansion medium. The expansion bag is provided on the outer peripheral surface of the inflatable portion 11. The expansion medium is filled between the expansion bag and the inflatable portion 11. The expansion medium is used to absorb water in the borehole so that the expansion medium expands. Specifically, Figure 1 As shown, the expansion bag is sleeved on the outer circumference of the inflatable part 11 and the expansion medium is located between the expansion belt and the inflatable part 11. The expansion bag is water-permeable and expandable. The expansion medium absorbs water and expands, so that the expansion part 12 seals the drill hole to prevent water leakage.

[0036] In some embodiments, the expansion bag is a permeable mesh, and the expansion medium is dried soybeans or dried kelp. Specifically, the permeable mesh can be a polyester fiber woven mesh, which is placed around the outer periphery of the inflatable portion 11, thereby ensuring that water in the borehole flows through the permeable mesh. Since dried soybeans or dried kelp have high water absorption, expansion, and biodegradability, using dried soybeans or dried kelp as the expansion medium ensures the expansion performance of the expansion medium, thereby reducing the cost of the borehole water blocking device 100.

[0037] In some embodiments, the borehole water sealing device 100 further includes a monitoring component (not shown in the figure), which is in communication with the inflatable portion 11 and is used to monitor the pressure within the sealing component 1. Specifically, the monitoring component is a pressure sensor, which can be disposed between the inflatable component 3 and the connector 2, so that the monitoring component can monitor the pressure within the sealing component 1 through the connector 2. When gas is introduced into the sealing component 1, the monitoring component prevents insufficient pressure in the sealing component 1 from causing sealing failure.

[0038] The borehole plugging method according to an embodiment of the present invention comprises steps S1 to S3 using the borehole water plugging device 100 according to any one of the above embodiments.

[0039] S1: Select the borehole to be plugged and determine the location and depth of the aquifer within the borehole. Specifically, select the borehole in the soft rock tunnel that needs to be plugged with borehole water, and determine the depth and location of the aquifer within the borehole by peering into the surrounding rock.

[0040] S2: Use the connector 2 of the borehole water sealing device 100 to transport the sealing member 1 of the borehole water sealing device 100 to the aquifer. Specifically, the inflation tube 31 is passed through the connector 2 to connect with the inflation part 11 (balloon rod valve needle joint), and the sealing member 1 is transported to the aquifer using the connector 2.

[0041] S3: Utilize the inflatable element 3 of the borehole water sealing device 100 to inflate the sealing element 1, causing the inflatable portion 11 of the sealing element 1 to expand. This causes the expansion portion 12 of the inflatable portion 11 to absorb water and expand, thereby sealing the borehole. Specifically, connect the other end of the inflatable tube 31 to a manual air pump 32. Press the manual air pump 32 to inflate the inflatable portion 11. With the inflatable portion 11 in the borehole, remove the detachable connecting rod 21 and the inflatable tube 31 by rotating them. Wait for the expansion element to expand to seal the borehole water.

[0042] The borehole water plugging device 100 according to the embodiment of the present invention has the advantages of simple steps and high plugging efficiency.

[0043] In step S3, there are multiple sealing members 1 in the borehole, and the multiple sealing members 1 are spaced apart along the length of the borehole. Thus, the borehole is sealed by multiple sealing members 1, thereby improving the sealing efficiency of the borehole water sealing device 100.
