[0002] With the continuous exploitation of mine resources, geological exploration work and mining activities are gradually developing towards deeper underground depths, and the difficulty of exploration and mining has become more difficult.

[0003] During the process of underground geological exploration boreholes, the situation of borehole water inrush often occurs. Without control measures, groundwater may quickly pour into the borehole and surrounding tunnels, affecting normal construction and posing certain construction safety risks. Therefore, it is necessary to set up a certain orifice device to quickly block the orifice when water inrush occurs, control the groundwater pouring into the tunnel when sudden water inrush occurs in the borehole, avoid groundwater from entering the tunnel, ensure the safety of the construction site, and guarantee the safety of drilling construction.

[0004] Currently, the commonly used method is to fix the orifice device at the orifice by configuring cement slurry. However, for the orifice device fixed with cement slurry, it will be affected by the vibration during the borehole construction process, resulting in cracks and gaps. When the borehole encounters water inrush, there is a situation of water seepage in the cracks and gaps around the configured borehole orifice device, which cannot meet the requirement of controlling groundwater and cannot effectively guarantee construction efficiency and construction safety.

[0031] During the process of underground geological exploration drilling, it is common to encounter the situation of water gushing out of the drill hole. Without control measures, groundwater may quickly pour into the drill hole and the surrounding tunnels, affecting normal construction and posing certain construction safety risks. Therefore, it is necessary to set up a certain orifice device to quickly seal the orifice when water gushing occurs, control the groundwater pouring into the tunnel when sudden water gushing occurs in the drill hole, avoid groundwater from entering the tunnel, ensure the safety of the construction site, and guarantee the safety of drilling construction.

[0032] Currently, the commonly used method is to fix the orifice device at the orifice by configuring cement slurry. However, for the orifice device fixed with cement slurry, it will be affected by the vibration during the drilling construction process, resulting in cracks and gaps. When water gushing occurs in the drill hole, there is a situation of water seepage through the cracks and gaps around the configured drill hole orifice device, which cannot meet the requirements of controlling groundwater and cannot effectively guarantee construction efficiency and construction safety.

[0033] In view of the above problems, the embodiment of the present application provides an orifice device for underground geological exploration drilling, which can effectively avoid the problem of water seepage after water gushing in the drill hole and guarantee construction efficiency and construction safety.

[0034] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0035] Figure 1 It is a cross-sectional schematic diagram of the overall structure of the orifice device for underground geological exploration drilling in the embodiment of the present application.

[0036] See Figure 1 , an orifice device for underground geological exploration drilling, is arranged and installed in the drill hole 7 for controlling water gushing in the drill hole, and includes: a first geological pipe 1, a first sealing pipe 2, a plug ring 3, a pressure ring 4, a first double-headed joint 5 and a second geological pipe 6.

[0037] The first geological pipe 1 is nested and installed inside the first sealing pipe 2, and the length of the first geological pipe 1 is longer than that of the first sealing pipe 2.

[0038] The first sealing pipe 2 is a single first sealing pipe 2.

[0039] The plug ring 3 is arranged and installed at the front end of the first geological pipe 1 and is threadedly connected to the first geological pipe 1; specifically: a chamfer is provided at the front end of the plug ring 3.

[0040] In this embodiment, by setting the chamfer, it is convenient for the tunneling and installation of the first geological pipe 1 and improves work efficiency.

[0041] The pressure ring 4 is nested and installed outside the first sealing pipe 2, at the rear end of the nesting of the first geological pipe 1; specifically: the pressure ring 4 is a sliding sleeve, and the material is steel or aluminum alloy.

[0042] The first double-headed joint 5 is installed at the rear end of the first geological pipe 1 and is threadedly connected to the first geological pipe 1, located at the rear end of the pressing ring 4. The first double-headed joint 5 is a stepped threaded joint.

[0043] The second geological pipe 6 is fixedly connected to the rear end of the first double-headed joint 5 by threading.

[0044] Specifically: A first fixed joint 601 is provided on the side wall at the rear end of the second geological pipe 6.

[0045] In this embodiment, the first fixed joint 601 is a hexagonal bolt, and the first double-headed joint 5 is fixed to the second geological pipe 6 by welding. By providing the first fixed joint 601, the second geological pipe 6 can be conveniently rotated, improving work efficiency.

[0046] Specifically: The first geological pipe 1, the first sealing pipe 2, the plugging ring 3, the first double-headed joint 5, and the second geological pipe 6 are all made of metal, specifically steel.

[0047] The specific installation and use process of the orifice device in the embodiment of the present application is as follows:

[0048] Installation process: Drill a borehole with a depth and diameter matching the second geological pipe 6 and clean it with clean water; install the plugging ring 3 on the front-end thread of the first geological pipe 1 and place the first geological pipe 1 at the bottom of the borehole; sequentially place and sleeve the first sealing pipe 2 and the pressing ring 4 outside the first geological pipe 1; install the first double-headed joint 5 on the rear-end thread of the first geological pipe 1, and then install the second geological pipe 6 on the rear-end thread of the first double-headed joint 5.

[0049] Use process: After installation, rotate the second geological pipe 6 to move forward, so that the pressing ring 4 moves forward synchronously. The distance between the pressing ring 4 and the plugging ring 3 is reduced, causing the first sealing pipe 2 to be compressed and deformed. The outer wall of the deformed first sealing pipe 2 closely adheres to the surrounding rock of the borehole wall, and the inner wall of the first sealing pipe 2 closely adheres to the outer wall of the first geological pipe 1, forming no gap among the first geological pipe 1, the first sealing pipe 2, and the surrounding rock of the borehole wall, ensuring that all the water gushing out of the borehole gushes out from inside the first geological pipe 1, achieving that the set water control orifice device does not generate cracks and interstitial water seepage after the vibration during the deep construction of the borehole, and realizing controllability when the borehole gushes water.

[0050] The technical solution provided by the embodiment of the present application includes the following beneficial effects:

[0051] In this application, by rotating the second geological pipe 6 to move forward, the first sealing pipe 2 is compressed and deformed. After deformation, the outer wall of the first sealing pipe 2 closely adheres to the surrounding rock of the borehole wall, and the inner wall of the first sealing pipe 2 closely adheres to the outer wall of the first geological pipe 1, forming no gap among the first geological pipe 1, the first sealing pipe 2, and the surrounding rock of the borehole wall. This can ensure that all the water gushing out from the borehole gushes out from inside the first geological pipe 1, achieving that the set water control orifice device does not generate cracks and interstitial water seepage after the vibration during the deep construction of the borehole, realizing controllability during borehole water gushing, effectively avoiding the water seepage problem after borehole water gushing, and ensuring construction efficiency and construction safety.
