Description

Technical Field

[0001] The utility model relates to the technical field of mine drilling, in particular to a rapid water plugging device for geological borehole water inrush. Background Technique

[0002] During geological exploration, mineral mining and underground engineering construction, drilling operations are often required. During or after the drilling process, situations where the groundwater level is relatively high or there are high-pressure aquifers may be encountered, resulting in water inrush in the borehole. Water inrush not only increases the construction difficulty and affects the project progress, but may also trigger geological disasters such as collapses and landslides, posing a threat to the safety of personnel and equipment.

[0003] Traditional water treatment methods include using cement slurry or other types of chemical grouting materials to plug the water inrush points. Although these methods can solve the problem to a certain extent, there are some deficiencies: the plugging speed is slow, the curing time of conventional grouting materials is relatively long, and the water inrush cannot be stopped immediately; the cost is high, the cost of special materials is high, and the overall cost increases when used in large quantities. In addition, traditional plugging methods are usually permanent plugging. After plugging, if the water inrush phenomenon at this place disappears or is solved, the borehole cannot be used anymore.

[0004] Regarding the problem of borehole water inrush, wooden wedges are mainly used for simple plugging in current mining areas. However, when the water pressure is relatively high, the wooden wedges may pop out, threatening safe production. Therefore, a safe and reliable borehole water inrush plugging device is needed. For this reason, we propose a rapid water plugging device for geological borehole water inrush. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a rapid water plugging device for geological borehole water inrush. The borehole is mainly plugged by a plugging block. The plugging block is inserted into the borehole with water inrush to achieve rapid plugging. The embedded column is fixed around the borehole by pouring concrete, and a safe and reliable plugging is formed in cooperation with the fixing frame, avoiding the problem that the plugging device is washed out by relatively high water pressure and threatening safe production, and can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a rapid water plugging device for geological borehole water inrush, including a plugging block. An airbag is arranged on the lower surface of the plugging block, and an air pump is arranged on the upper surface of the plugging block. The air outlet end of the air pump is connected to an air inlet pipe, and the air inlet pipe passes through the center of the plugging block and extends into the airbag; a plurality of connecting rods are uniformly arranged on the outer peripheral side surface of the upper part of the plugging block, a fixing frame is arranged at the end of the connecting rod, a plurality of extension plates are uniformly arranged on the inner surface of the fixing frame, screw holes are opened on the extension plates, installation screws are threadedly connected in the screw holes, and embedded columns are threadedly connected to the outer surface of the bottom end of the installation screws.

[0007] As a preferred technical solution of the present utility model, a plurality of through holes are evenly formed on the outer surface of the embedded column.

[0008] As a preferred technical solution of the present utility model, a conical head is fixedly arranged at the bottom end of the embedded column.

[0009] As a preferred technical solution of the present utility model, a feed pipe is communicated and arranged on the upper side of the air inlet pipe, and a valve is arranged at the connection between the feed pipe and the air inlet pipe.

[0010] As a preferred technical solution of the present utility model, a rubber pad is sleeved on the outer surface of the plugging block.

[0011] As a preferred technical solution of the present utility model, the plugging block includes a top, a reduced-diameter part and a bottom which are arranged in sequence from top to bottom. The diameter of the top is larger than that of the bottom. The reduced-diameter part is frustum-shaped, and the diameter of the upper end surface of the reduced-diameter part is equal to that of the top, and the diameter of the lower end surface of the reduced-diameter part is equal to that of the bottom.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: The drilling hole is mainly plugged by the plugging block. The plugging block is inserted into the drilling hole with water gushing to achieve rapid plugging. Then, the air pump is used to inflate the airbag to improve the plugging effect and prevent water from seeping out. After the plugging is completed, an external force is applied to temporarily fix the plugging block, such as using a heavy object or an excavator to press it tightly. Then, a pit is quickly dug around the drilling hole, and the embedded column is inserted into the pit. The position of the fixing frame is adjusted, and the installation screw is screwed into the screw hole on the extension plate and threadedly connected with the screw hole formed at the top end of the embedded column to fix the embedded column and the fixing frame. Then, concrete is poured into the pit and cured to form a shape. The embedded column is fixed around the drilling hole. Then, the external heavy object or excavator can be removed, forming a safe and reliable plugging, avoiding the problem that the plugging device is washed out by the large water pressure and threatening the safety production. At the same time, a large amount of special materials are not required, reducing the plugging cost. After the water gushing phenomenon disappears in the later stage, the installation screw can be removed, and then the plugging block and the fixing frame can be recycled and reused, and the drilling hole can still be put into use, further reducing the drilling cost.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1 - 3 , the present invention provides a technical solution: a rapid water plugging device for geological drilling water inrush, including a plugging block 1, mainly plugging the drilling hole through the plugging block 1, and inserting the plugging block 1 into the drilling hole with water inrush to achieve rapid plugging; an airbag 2 is arranged on the lower surface of the plugging block 1, an air pump 11 is arranged on the upper surface of the plugging block 1, the air outlet end of the air pump 11 is connected with an air inlet pipe 10, and the air inlet pipe 10 passes through the center of the plugging block 1 and extends into the airbag 2, and the air pump 11 is used to inflate the airbag 2 to improve the plugging effect and avoid water seepage outward.

[0019] The air pump 11 is powered by an external power supply and is provided with a switch; the air pump 11 is a commonly used electronic component in the prior art, and its specific structure, working principle, circuit connection, etc. are all well-known technologies and will not be elaborated here.

[0020] A plurality of connecting rods 4 are uniformly arranged on the outer peripheral side surface of the upper part of the plugging block 1, a fixing bracket 5 is arranged at the end of the connecting rod 4, a plurality of extension plates are uniformly arranged on the inner surface of the fixing bracket 5, screw holes are opened on the extension plates, mounting screws 6 are threadedly connected in the screw holes, the outer surface of the bottom end of the mounting screw 6 is threadedly connected with an embedded column 7, and after plugging, the plugging block 1 is temporarily fixed by applying an external force, such as pressing with a heavy object or an excavator, etc., and then quickly dig a pit around the drilling hole, insert the embedded column 7 into the pit, adjust the position of the fixing bracket 5, screw the mounting screw 6 into the screw hole on the extension plate and threadedly connect it with the screw hole opened at the top end of the embedded column 7 to fix the embedded column 7 and the fixing bracket 5, then pour concrete into the pit and cure it into shape, the embedded column 7 is fixed around the drilling hole, and then the external heavy object or excavator, etc. can be removed, forming a safe and reliable plugging, avoiding the problem that the plugging device is washed out by large water pressure and threatening production safety, and at the same time, a large amount of special materials do not need to be used, reducing the plugging cost. After the water inrush phenomenon disappears later, the mounting screw 6 can be removed, and then the plugging block 1 and the fixing bracket 5, etc. can be recycled, and the drilling hole can still be put into use, further reducing the drilling cost.

[0021] In a preferred technical solution, a plurality of through holes 8 are evenly formed on the outer surface of the embedded column 7. Reinforcing bars or the like can penetrate through the through holes 8 horizontally to improve the connection strength with the concrete, thereby further enhancing the reliability of the plugging.

[0022] In a further preferred technical solution, a tapered head 9 is fixedly arranged at the bottom end of the embedded column 7. The bottom of the tapered head 9 is a tip, which can make it more convenient for the embedded column 7 to be inserted into the ground.

[0023] Optionally, when the geology around the drilling hole is relatively hard rock, the embedded column 7 can be replaced with an expansion bolt or the like. A method of first drilling a small hole and then driving the expansion bolt and connecting it to the installation screw 6 can be adopted.

[0024] In a preferred technical solution, a feed pipe 12 is communicated and arranged on the upper side of the air inlet pipe 10. When it is determined that the drilling hole is no longer in use and long-term plugging is required, concrete or other materials can be put into the airbag 2 through the feed pipe 12 to fill it up, so as to avoid the risk that the plugging block 1 is washed out due to excessive pressure in the later stage. After the airbag 2 is filled, devices such as the air pump 11 and the fixing frame 5 can be removed and recycled.

[0025] Further preferably, a valve 13 is arranged at the connection between the feed pipe 12 and the air inlet pipe 10. The valve 13 is a three-way valve for controlling the on-off of the feed pipe 12 and the air inlet pipe 10. When the feed pipe 12 is communicated with the air inlet pipe 10, the connection between the air inlet pipe 10 and the air outlet end of the air pump 11 is closed; conversely, the connection between the air inlet pipe 10 and the air outlet end of the air pump 11 is communicated.

[0026] In a preferred technical solution, a rubber pad 3 is sleeved on the outer surface of the plugging block 1. The rubber pad 3 is used to improve the sealing performance between the plugging block 1 and the inner wall of the drilling hole during the initial rapid plugging, and to avoid the influence of water seepage on the fixation of the embedded column 7 and so on.

[0027] In a preferred technical solution, the plugging block 1 includes a top portion 14, a reduced-diameter portion 15 and a bottom portion 16 which are arranged in sequence from top to bottom. The diameter of the top portion 14 is larger than the diameter of the bottom portion 16. The reduced-diameter portion 15 is frustum-shaped, and the diameter of the upper end surface of the reduced-diameter portion 15 is equal to the diameter of the top portion 14, and the diameter of the lower end surface of the reduced-diameter portion 15 is equal to the diameter of the bottom portion 16, so that the plugging block 1 can be applicable to plugging of drilling holes with different diameters, greatly improving the universality of the device and making it more valuable for recycling. The rubber pad 3 is also divided into three corresponding parts like the plugging block 1, and the diameter of the airbag 2 after inflation is slightly larger than the diameter of the top portion 14 to ensure its plugging effect.

[0028] The parts not disclosed in the present utility model are all prior arts, and their specific structures, materials and working principles will not be elaborated herein. Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
