Description

Technical Field

[0001] The invention relates to the technical field of hydrogeological deep hole well construction, in particular to a gravel filling device and method for hydrogeological deep hole well construction in sandstone-type uranium mines. Background Art

[0002] Hydrogeological deep hole construction in sandstone-type uranium deposits refers to deep hole construction technology, which is one of the key steps in the uranium exploration process. This technology involves drilling a vertical or inclined hole deep underground to facilitate subsequent geological understanding and hydrogeological research. Since sandstone-type uranium deposits are usually located in deeper strata, deep hole construction technology is particularly important in the exploration and mining of sandstone-type uranium deposits. The gravel filling method involved in the present invention is intended to solve the technical difficulties encountered in the hydrogeological deep hole construction process in sandstone-type uranium deposits, improve the efficiency and quality of well construction, and ensure the stability and safety of the mine.

[0003] Patent document CN1228494A discloses a vacuum deep-well reinforcement method for thick soft soil foundations. The method involves drilling a hole through the soft soil layer to create a deep well; placing a well pipe with a filter layer into the deep well; lowering a deep-well pump to the bottom of the well; sealing the wellhead; and evacuating the deep well with a vacuum pump, allowing pore water in the soil layer to drain into the deep well. When the water level in the deep well reaches a predetermined upper limit, the deep-well pump automatically pumps water; when it reaches a lower limit, the pump automatically stops. This method achieves a relatively uniform reinforcement effect across the entire soft soil layer, regardless of the depth or area being reinforced. It is widely used in projects such as roadbeds, docks, plazas, and buildings.

[0004] Gravel filling in a well is usually done by pumping mud into a gravel filling booster tank through a mud pump. The gravel in the tank is pressurized by air compression and the slurry is stored in the tank. Then, a gravel-dropping pipe is used to accurately fill the gravel to the designated target layer. However, the mud is relatively viscous and can easily cause blockage when passing through a thin gravel-dropping pipe, affecting the efficiency and quality of the gravel filling. In addition, when the mud in the gravel filling booster tank is filled into the designated target layer through the gravel-dropping pipe, the mud in the booster tank is reduced, which will cause the pressure inside the booster tank to decrease, which may cause the booster tank to be unstable, thereby affecting the continuity and uniformity of the gravel filling.

In addition, when the mud in the gravel-filling boosting tank is passed through the gravel-dropping tank to fill the gravel to the designated target layer, the mud in the boosting pipe is reduced, thereby causing the pressure inside the boosting tank to decrease, which may cause the boosting tank to be unstable, thereby affecting the continuity and uniformity of the gravel filling.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The present invention provides a gravel filling booster tank, so that the mixture of gravel and mud is fully stirred and mixed in the booster tank, thereby improving the uniformity and continuity of the gravel filling.

When the mud falls into the inner wall of the gravel-filling booster tank 1, the shaking of the dividing rod 699 makes the mud falling on the dividing rod 699 evenly dispersed, avoiding local accumulation of mud on the inner wall of the gravel-filling booster tank 1, and achieving uniform spreading of the mud. After the gravel material is poured in, the shaking of multiple dividing rods 699 makes the mud float and evenly blend with the gravel material. Through this mechanical movement, the mud can be evenly distributed on the inner wall of the gravel-filling booster tank 1, avoiding the problems of mud accumulation and uneven mixing, and ensuring the efficiency and quality of the gravel filling operation.

[0049] Working principle: When discharging mud and gravel, the motor 514 should be started first. The start of the motor 514 will drive the transmission worm 515 to rotate, and then the outer ring gear 525 will engage with it, driving the discharge pipe connecting plate 524, the barrel-shaped discharge pipe 523, the barrel-shaped discharge pipe inlet pipe 527 and the bottom ring gear 526 to rotate synchronously. As the barrel-shaped discharge pipe inlet pipe 527 rotates, the arc-shaped connecting rod 528 and the auger rod 529 also rotate. The rotation of the auger rod 529 will pull the mud and gravel into the slurry. The gravel is discharged from the cylindrical discharge pipe 523. The function of the auger rod 529 is to effectively prevent the mud and gravel from being blocked during the discharge process. When the mud and gravel are discharged, the motor 514 should be started first. The start of the motor 514 will drive the transmission worm 515 to rotate, and then the outer gear ring 525 will engage with it, driving the discharge pipe connecting plate 524, the cylindrical discharge pipe 523, the cylindrical discharge pipe inlet pipe 527 and the bottom gear ring 526 to rotate synchronously. As the material pipe 527 rotates, the arc-shaped connecting rod 528 and the auger rod 529 also rotate accordingly. The rotation of the auger rod 529 discharges the mud and gravel from the cylindrical discharge pipe 523. The function of the auger rod 529 is to effectively prevent the mud and gravel from being blocked during the discharge process. At the same time, the rotation of the bottom gear ring 526 will cause the gears 518 on both sides to engage and rotate, thereby driving the gear rotating rod 517 and the conical gear 519 to rotate synchronously. The rotation of the two conical gears 519 will rotate with the second conical gear 520. The screw rod 522 is meshed with each other, thereby driving the screw rod 522 to rotate. The rotation of the screw rod 522 will mesh with the inner wall of the connecting pipe 532, so that the connecting pipe 532 is axially lifted through the outer wall of the screw rod 522, thereby pushing the lifting plate body 531 to slide upward along the outer wall of the cylindrical discharge pipe and feed pipe 527. This action will change the size of the space on the inner wall of the gravel filling booster tank 1, ensuring that the pressure inside the gravel filling booster tank 1 will not drop due to the reduction of mud, thereby maintaining the stability of the booster tank and ensuring the continuity and uniformity of the gravel filling operation.

[0050] When the slurry is fed to the inner wall of the gravel-filled booster tank 1, in order to prevent the slurry from piling up in one area on the inner wall of the gravel-filled booster tank 1 and not being evenly spread on the inner wall of the gravel-filled booster tank 1, and the gravel material is not evenly mixed after being poured in, at this time, the second motor 64 is started, and the second outer gear ring 68 is driven by the second worm 65, thereby rotating the rotating disk 66. The rotation of the rotating disk 66 drives the top gear ring 67 to rotate, and the top gear ring 67 is engaged with the second gear 693 on the turntable rotating rod 692, so that the turntable 694 rotates. The rotation of the turntable 694 drives the rotating block 695 to slide in the elliptical slide block 696, thereby pushing the push-pull rod 697 to move up and down. , the push-pull rod 697 is transmitted to the push-pull plate 698, and the dividing rod 699 on the push-pull plate 698 rises and falls and shakes back and forth. When the mud falls into the inner wall of the gravel-filling booster tank 1, the shaking of the dividing rod 699 makes the mud falling on the dividing rod 699 evenly dispersed, avoiding local accumulation of mud on the inner wall of the gravel-filling booster tank 1, and achieving uniform spreading of the mud. After the gravel material is poured in, the shaking of multiple dividing rods 699 makes the mud float and evenly blend with the gravel material. Through this mechanical movement, the mud can be evenly distributed on the inner wall of the gravel-filling booster tank 1, avoiding the problems of mud accumulation and uneven mixing, and ensuring the efficiency and quality of the gravel filling operation.

[0051] The gravel filling method for deep hole construction in hydrogeological sandstone uranium deposits in the embodiment of the present invention comprises the following steps:

[0052] Step 1: Secure the gravel-filled booster tank 1 firmly at a predetermined position via the booster tank support frame 2 to ensure its stability and safety;

[0053] Step 2: Start the mud pump 10 and inject mud into the gravel filling booster tank 1 through the mud pipe 7 and the slurry inlet 3;

[0054] Step 3: After injecting mud into the inner wall of the gravel-filled booster tank 1, gravel is filled into the inner wall through the top of the gravel-filled booster tank 1. During the process of filling the gravel, if the pressure on the inner wall of the gravel-filled booster tank 1 is too high, part of the mud is pumped back into the mud tank 11 through the mud pump 10 and the mud return pipe 8;

[0055] Step 4: Using the air compression function inside the gravel filling booster tank 1, the gravel and mud are injected into the drilling rig derrick 15, and the gravel is accurately placed into the designated target layer.

[0056] Specifically, the process of securing the gravel-filled booster tank involves: selecting a location: determining the installation location of the gravel-filled booster tank based on geological survey data and design requirements; installing the support frame: installing the booster tank support frame in the predetermined location to ensure its stability and load-bearing capacity; and securing the booster tank: placing the gravel-filled booster tank on the support frame and securely securing it with a fixture to prevent movement or tilting during operation.

[0057] Mud injection includes: Equipment inspection: Before starting the mud pump, check that the mud pipe and slurry inlet are securely connected to ensure there are no leaks; Starting the mud pump: Start the mud pump, pump mud from the mud tank through the mud pipe, and inject it into the gravel filling booster tank through the slurry inlet. Monitoring mud flow: During the mud injection process, monitor the mud flow and pressure in real time to ensure it meets design requirements.

[0058] Gravel filling includes: Slurry injection: Injecting slurry into the inner wall of the gravel filling booster tank; Gravel filling: Filling gravel into the inner wall of the gravel filling booster tank from the top. Gravel filling should be evenly distributed during the filling process to avoid local accumulation; Pressure monitoring: During the gravel filling process, the pressure on the inner wall of the gravel filling booster tank is monitored in real time. If the pressure is too high, some of the mud is pumped back into the mud tank through the mud pump and mud return pipe to reduce the pressure.

[0059] Injecting gravel and mud includes: starting the air compression function: using the air compression function inside the gravel filling booster tank to mix and pressurize the gravel and mud; injecting into the drilling rig derrick: injecting the pressurized gravel and mud under the drilling rig derrick through the pipeline to ensure that the injection process is smooth and leak-free; precise delivery: according to geological exploration data and design requirements, the gravel is accurately delivered to the designated target layer to ensure that the gravel is evenly distributed and meets the design requirements.
