Description

Technical Field

[0001] This invention belongs to the field of geological exploration technology, specifically relating to a segmented grouting detection device based on geological exploration and its usage method. Background Technology

[0002] Geological exploration involves sending signals underground using exploration instruments, receiving the reflected signals at different locations on the surface, processing the received signals to analyze the composition and structure of rock strata, and determining the content of various underground substances. Geological exploration is also conducted during mineral prospecting to discover industrially significant mineral deposits. It aims to ascertain the quality and quantity of minerals, as well as the technical conditions for their extraction and utilization, providing the mineral reserves and geological data necessary for mine construction and design. This involves investigating and studying the geological conditions of a specific area, including rocks, strata, structures, minerals, hydrology, and geomorphology.

[0003] Karst strata, also known as karst landforms, refer to various landforms formed by the dissolution, transportation, and deposition of soluble rocks by water, such as caves. Construction in these geological formations is inconvenient, requiring frequent exploration of underground caves and separate grouting of each cave. This exploration and construction method has several problems: First, when exploration instruments transmit signals underground, the high-frequency signals attenuate quickly due to the loose surface layer, with only low-frequency signals propagating to deeper layers, resulting in very low resolution of underground rock layer exploration. Currently, the only solution is to address the propagation of high-frequency signals to the shallow surface layer for fine exploration. Enabling deeper, more precise exploration remains a difficult problem. Second, the operational pattern of detection → drilling → rod withdrawal → grouting → rod advancement → drilling → rod withdrawal → grouting... is complex and inefficient. Third, recovering combustible gases from caves is inconvenient, wasting energy. Fourth, separate grouting is inconvenient to operate.

[0004] In conclusion, conducting research on existing geological exploration and grouting technologies is of great significance. Summary of the Invention

[0016] Secondly, the present invention provides a method for using the segmented grouting detection device based on geological exploration as described in the first aspect, comprising the following steps:

[0017] S1. The equipment is transported to the drilling location at the construction site and the operation begins. The drilling bit and the small multi-functional drill bit are connected together and work synchronously to form a borehole. The small multi-functional drill bit first enters the foundation, and the ultrasonic radar exploration module begins to work. The transmitter in the ultrasonic radar exploration module generates elastic incident waves to monitor and analyze whether there are karst caves and record the location information.

[0018] S2. Upon reaching the karst cave area, the first and second drive motors stop operating synchronously, bringing the shaft-blocking frame out of the small multi-functional drill bit and into the through-hole hollow shaft. The gas pump starts, and the gas in the karst cave is discharged through the small multi-functional drill bit, the through-hole hollow shaft, the through-hole large hollow shaft, the ventilation hole, and the gas collection pipe. The extracted gas is recycled and processed for utilization, reducing energy consumption. Furthermore, the pressure decreases as the gas in the karst cave is discharged.

[0019] S3. After the gas collection in the multi-cavity area is completed, it is connected to the external grouting equipment through the grouting pipe connection port to prepare for grouting operation;

[0020] S4. Start the grouting equipment and grout the karst cave through the first grouting pipe, the second grouting pipe and the grouting port. At the same time, the sleeve valve pipes in other karst caves are opened by the grout and grouting begins simultaneously. This achieves one-time grouting instead of multi-cavity step-by-step grouting, improving efficiency and reducing energy consumption.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention adopts geological exploration technology combining drill bit and ultrasonic radar. During the drilling process, the radar is brought underground to conduct predictive analysis of karst strata. The operation process is simplified from the original detection, drilling, rod withdrawal, grouting, rod advance, drilling, rod withdrawal, grouting and filling to detection, drilling, gas extraction, drilling, gas extraction, grouting and filling. This allows detection, drilling, gas extraction and grouting to be carried out in one integrated manner without rod withdrawal. At the same time, one-time grouting replaces multiple grouting, improving operation efficiency. Attached Figure Description

[0039] like Figures 1 to 6 and attached Figure 10 As shown, the buffer frame 3 includes a first buffer seat 31, a second buffer seat 32, and a third buffer seat 33 connected sequentially from front to back. A set of drilling slides 4 are respectively installed on the upper part of the first buffer seat 31 and the third buffer seat 33. A first mounting seat 311 is provided at the front of the first buffer seat 31. The first buffer seat 31 and the second buffer seat 32 are connected by a first buffer spring 322. A positioning ring hole 321 is provided in the middle of the second buffer seat 32. The drilling slide 4 is connected to the first mounting seat 311 by a first anti-vibration spring frame 13. The drilling slide 4 is connected to the second buffer seat 32 by a second anti-vibration spring frame 14.

[0040] like Figures 2 to 5 As shown, the second buffer seat 32 and the third buffer seat 33 are connected by a second buffer spring 323. The third buffer seat 33 is provided with a second mounting seat 331 at the rear. The second mounting seat 331 is provided with a counterweight. The drilling slide 4 is connected to the second mounting seat 331 by a first anti-vibration spring frame 13.

[0041] like Figures 1 to 4 As shown, the top of the drilling slide 4 is provided with a first drive motor 41, the output end of the first drive motor 41 is connected to a first lead screw 42, a first slide 43 is sleeved on the first lead screw 42, and a second drive motor 5 is connected to the front of the first slide 43; the output end of the second drive motor 5 is connected to a rotating rod 51, the bottom of the rotating rod 51 is provided with four sets of rotating frames 52, and the bottom of the rotating frames 52 is equipped with a drilling rotating rod 53; the top of the first grouting pipe 7 is provided with a grouting pipe connection port 71, which can be connected to external grouting equipment; the upper part of the vent 531 is provided with a gas sampling pump 6, and the upper part of the gas sampling pump 6 is provided with a gas sampling pipe 61.

[0042] Furthermore, the equipment is transported to the drilling location at the construction site. During use, the two sets of first drive motors 41 start synchronously. The first drive motor 41 drives the first lead screw 42 to rotate, the first lead screw 42 drives the first slide block 43 to move downward, and the first slide block 43 drives the second drive motor 5 to move downward. During the drilling process of moving downward, a drill channel 19 is formed, and the first anti-vibration spring frame 13 on both sides and the second anti-vibration spring frame 14 on the inner side dampen the pile driving slide block 4 to prevent the drill from deviating from the position.

[0043] Furthermore, the drilling bit 8 and the small multi-functional drill bit 11 are connected together and operate synchronously. During drilling, the shaft blocking frame 113 is located at the bottom of the small multi-functional drill bit 11 to block the small multi-functional drill bit 11 and the grouting port 121. The small multi-functional drill bit 11 enters the ground first, and the ultrasonic radar exploration module 10 starts to operate to determine whether there is a karst cave 20.

[0044] Furthermore, by utilizing the propagation and reflection characteristics of ultrasound in a medium, an ultrasonic pulse is emitted through the transmitter 101, and the waveform and time of its reflection are measured by the receiver 102. The topographic features of the underground cave 20 are then determined by the analyzer 103. Example 2:

[0045] like Figures 3 to 8 As shown, in one embodiment of the present invention, a segmented grouting detection device based on geological exploration, based on embodiment 1, is provided with a base frame 111 at the bottom of the small multi-functional drill bit 11, and a base shaft frame 112 is provided on both sides of the base frame 111. The bottom of the second grouting pipe 12 is connected to the base frame 111, and grouting ports 121 are provided on both sides of the bottom of the second grouting pipe 12.

[0046] like Figures 6 to 9 As shown, the small multi-functional drill bit 11 is provided with a shaft-blocking frame 113 inside. The shaft-blocking frame 113 is slidably sleeved on the outside of the second grouting pipe 12. The shaft-blocking frame 113 can block the grouting port 121.

[0047] like Figures 6 to 14 As shown, miniature slides 91 are installed on both sides of the bottom of the through-hole shaft 96. A third drive motor 92 is provided on the upper part of the miniature slide 91. The output end of the third drive motor 92 is connected to a second lead screw 93. A second slide 94 is sleeved on the second lead screw 93. A connecting frame 95 is provided at the front end of the second slide 94. The bottom of the connecting frame 95 is connected to the shaft blocking frame 113.

[0048] Furthermore, when the small multi-functional drill bit 11 drills into the karst cave, the first drive motor 41 and the second drive motor 5 stop working simultaneously, the third drive motor 92 starts, and the second slide block 94 moves upward along the second lead screw 93 to bring the shaft block 113 out of the small multi-functional drill bit 11 and into the through small hollow shaft 96. Then, the gas pump 6 starts to discharge the gas in the karst cave through the small multi-functional drill bit 11, the through small hollow shaft 96, the through large hollow shaft 54, the vent hole 531 and the gas collection pipe 61. The extracted gas is recycled and processed for utilization, reducing energy consumption. Moreover, the gas in the karst cave 20 is discharged, and the pressure decreases.

[0049] Furthermore, after the gas is discharged, it is connected to the external grouting equipment through the grouting pipe connection port 71. The grouting equipment is started, and grouting is performed on the karst cave 20 through the first grouting pipe 7, the second grouting pipe 12 and the grouting port 121. At the same time, the sleeve valve pipes 16 in each other karst cave 20 are pushed open by the grout, and grouting begins simultaneously.

[0050] Working principle:

[0051] The equipment is transported to the drilling location at the construction site. During use, the two sets of first drive motors 41 start synchronously. The first drive motor 41 drives the first lead screw 42 to rotate, the first lead screw 42 drives the first slide block 43 to move downward, and the first slide block 43 drives the second drive motor 5 to move downward. During the drilling process, a drill channel 19 is formed, and the first anti-vibration spring frame 13 on both sides and the second anti-vibration spring frame 14 on the inner side dampen the pile driving slide block 4 to prevent the drill from deviating from its position.

[0052] During operation, the drilling bit 8 and the small multi-functional drill bit 11 are connected together and work synchronously. During drilling, the shaft blocking frame 113 is located at the bottom of the small multi-functional drill bit 11, sealing the small multi-functional drill bit 11 and the grouting port 121. The small multi-functional drill bit 11 enters the ground first, and the ultrasonic radar exploration module 10 starts to work. The transmitter 101 in the ultrasonic radar exploration module 10 generates elastic incident ultrasonic waves. The receiver 102 detects the reflected waves formed by the geological structure of the soil layer by the elastic incident ultrasonic waves and transmits the information to the analyzer 103 for analysis to determine whether there is a karst cave 20. In this way, the geological exploration technology of using the small multi-functional drill bit 11 in combination with the ultrasonic radar exploration module 10 is realized. During the drilling process, the ultrasonic radar exploration module 10 is brought underground to conduct predictive analysis of karst strata.

[0053] When the small multi-functional drill bit 11 drills into the karst cave, the first drive motor 41 and the second drive motor 5 stop working simultaneously, the third drive motor 92 starts, and the second slide block 94 moves upward along the second lead screw 93 to bring the shaft block 113 out of the small multi-functional drill bit 11 and into the through small hollow shaft 96. Then the gas pump 6 starts to discharge the gas in the karst cave through the small multi-functional drill bit 11, the through small hollow shaft 96, the through large hollow shaft 54, the vent hole 531 and the gas collection pipe 61. The extracted gas is recycled and processed for utilization, reducing energy consumption. Moreover, the gas in the karst cave 20 is discharged, and the pressure decreases.

[0054] After the gas is discharged, it is connected to the external grouting equipment through the grouting pipe connection port 71. The grouting equipment is started, and grouting is performed on the karst cave 20 through the first grouting pipe 7, the second grouting pipe 12 and the grouting port 121. At the same time, the sleeve valve pipe 16 in each other karst cave 20 is pushed open by the grout and grouting begins simultaneously.

[0055] In summary, the work process can be simplified from the original steps of inspection, drilling, rod withdrawal, changing to a smaller drill bit, rod insertion and drilling, rod withdrawal, gas extraction, and grouting to inspection, drilling, gas extraction, drilling, gas extraction, and grouting. This allows for the integration of inspection, drilling, gas extraction, and grouting without the need for rod withdrawal. Furthermore, a single grouting operation replaces multiple grouting operations, improving work efficiency, saving energy and reducing energy consumption. The collected and recovered gas can be processed into a new energy source, making it energy-saving and environmentally friendly. Example 3:

[0056] This embodiment provides a method for using the segmented grouting detection equipment based on geological exploration as described in Embodiment 1 or Embodiment 2, the steps of which are as follows:

[0057] S1. The equipment is transported to the drilling location at the construction site and the operation begins. The drilling bit 8 and the small multi-functional drill bit 11 are connected together and work synchronously to form a borehole 19. The small multi-functional drill bit 11 first enters the foundation. The ultrasonic radar exploration module 10 starts to work. The transmitter 101 in the ultrasonic radar exploration module 10 generates elastic incident ultrasonic waves to monitor and analyze whether there is a karst cave 20 and records the location information.

[0058] S2. Upon reaching the area of ​​cave 20, the first drive motor 41 and the second drive motor 5 stop working simultaneously, and the shaft blocking frame 113 is brought out of the small multi-functional drill bit 11 and enters the through small hollow shaft 96. The gas pump 6 is started, and the gas in the cave is discharged through the small multi-functional drill bit 11, the through small hollow shaft 96, the through large hollow shaft 54, the ventilation hole 531 and the gas collection pipe 61. The gas collected is recycled and processed for utilization, reducing energy consumption. Moreover, the pressure in cave 20 decreases after the gas is discharged.

[0059] S3. After gas collection is completed in the multi-cavity area, connect it to the external grouting equipment through the grouting pipe connection port 71 to prepare for grouting operation.

[0060] S4. Start the grouting equipment and grout the karst cave 20 through the first grouting pipe 7, the second grouting pipe 12 and the grouting port 121. At the same time, the sleeve valve pipes 16 in each other karst cave 20 are opened by the grout and grouting begins simultaneously. This achieves one-time grouting instead of step-by-step grouting of multiple karst caves 20, improving efficiency and reducing energy consumption.

10. The method of using a segmented grouting detection device based on geological exploration according to claim 9, characterized in that, Includes the following steps: S1. The equipment is transported to the drilling location at the construction site and the operation begins. The drilling bit (8) and the small multi-functional drill bit (11) are connected together and operate synchronously to form a borehole (19). The small multi-functional drill bit (11) first enters the foundation. The ultrasonic radar exploration module (10) starts to operate. The transmitter (101) in the ultrasonic radar exploration module (10) generates elastic incident ultrasonic waves to monitor and analyze whether there is a karst cave (20) and records the location information. S2. Upon reaching the cave (20) area, the first drive motor (41) and the second drive motor (5) stop working simultaneously, and the shaft blocking frame (113) is brought out of the small multi-functional drill bit (11) and enters the through small hollow shaft (96). The gas pump (6) is started, and the gas in the cave is discharged through the small multi-functional drill bit (11), the through small hollow shaft (96), the through large hollow shaft (54), the ventilation hole (531) and the gas collection pipe (61). The gas collected is recycled and processed for use, reducing energy consumption. Moreover, the gas in the cave (20) is discharged, and the pressure decreases. S3. After the gas collection in the multi-cavity area is completed, it is connected to the external grouting equipment through the grouting pipe connection port (71) to prepare for grouting operation; S4. Start the grouting equipment and grout the karst cave (20) through the first grouting pipe (7), the second grouting pipe (12) and the grouting port (121). At the same time, the sleeve valve pipe (16) in each other karst cave (20) is pushed open by the grout and grouting starts simultaneously. This realizes one-time grouting instead of multi-karst cave (20) step-by-step grouting, improves efficiency and reduces energy consumption.
