Description

Technical Field

[0001] The invention belongs to the technical field of geological exploration, and in particular relates to a segmented grouting detection device based on geological detection and a use method thereof. Background Art

[0002] Geological exploration is to send signals underground through exploration instruments, receive signals reflected from underground at different locations on the surface, process various signals received, analyze the composition and structure of rock formations, and also analyze the content of various substances underground. Geological exploration is to investigate and study the geological conditions of rocks, strata, structures, minerals, hydrology, landforms, etc. in a certain area in order to find out the quality and quantity of minerals and the technical conditions for mining and utilization, and to provide the mineral reserves and geological data required for mine construction design.

[0003] The molten rock formation is also called karst landform. Karst landform refers to various landforms formed by the dissolution, transportation and deposition of soluble rocks, such as caves. This type of geological construction is inconvenient, and it is necessary to frequently explore the underground caves and grout each cave separately. This type of exploration and construction operation mode has certain problems. First, when the exploration instrument transmits signals to the underground, the high-frequency signal excited quickly decays due to the loose surface layer. Only the low-frequency signal propagates to the deep, resulting in too low exploration resolution of the underground rock formation. At present, we can only solve the problem of high-frequency signals propagating to the shallow surface layer to achieve fine exploration of the shallow surface layer. As for how to make the high-frequency signal propagate deeper underground and realize deep precise exploration, it is still a difficult problem to solve; second, the operation mode of detection → drilling → rod withdrawal → grouting → rod feeding → drilling → rod withdrawal → grouting... is complex and inefficient; third, the recovery of combustible gas in the cave is inconvenient, which wastes energy; third, separate grouting is required, which is inconvenient to operate.

[0021] As Figures 1 to 6 and attached Figure 10 As shown in the figure, the buffer frame seat 3 includes a first buffer seat 31, a second buffer seat 32 and a third buffer seat 33 connected in sequence from front to back. A group of drilling slide seats 4 are respectively installed on the upper parts of the first buffer seat 31 and the third buffer seat 33. A first mounting seat 311 is provided at the front part of the first buffer seat 31. The first buffer seat 31 and the second buffer seat 32 are connected through a first buffer spring 322. A positioning ring hole 321 is arranged in the middle of the second buffer seat 32. The drilling slide seat 4 and the first mounting seat 311 are connected through a first anti-seismic spring frame 13. The drilling slide seat 4 and the second buffer seat 32 are connected through a second anti-seismic spring frame 14.

A second mounting seat 331 is provided at the rear part of the third buffer seat 33. A counterweight is arranged inside the second mounting seat 331. The drilling slide seat 4 and the second mounting seat 331 are connected through a first anti-seismic spring frame 13.

[0023] As Figures 1 to 4 shown, a first driving motor 41 is provided on the top of the drilling slide 4. The output end of the first driving motor 41 is connected to a first lead screw 42. A first sliding seat 43 is sleeved on the first lead screw 42. The front part of the first sliding seat 43 is connected to a second driving motor 5.

A gas extraction pipe 61 is provided above the gas extraction pump 6.

[0024] Further, the equipment is transported to the drilling position at the construction site. During use, the two first driving motors 41 are started synchronously. The first driving motor 41 drives the first lead screw 42 to rotate. The first lead screw 42 drives the first sliding seat 43 to move downward. The first sliding seat 43 drives the second driving motor 5 to move downward. A drilling channel 19 is formed during the downward drilling process. The first anti-vibration spring frames 13 on both sides and the second anti-vibration spring frames 14 on the inner side dampen the vibration of the driving slide 4 to prevent the drilling from deviating from the position.

[0025] Further, the drilling bit 8 and the small multi-functional bit 11 are connected together for synchronous operation. During the drilling operation, the blocking shaft frame 113 is at the bottom of the small multi-functional bit 11 to block the small multi-functional bit 11 and the grouting port 121. The small multi-functional bit 11 first enters the ground, and the ultrasonic radar exploration module 10 starts to operate to determine whether there is a karst cave 20.

[0026] Further, by utilizing the propagation and reflection characteristics of ultrasonic waves in a medium, an ultrasonic pulse is emitted through the transmitter 101, and then the waveform and time of its reflection are measured through the receiver 102. The terrain characteristics of the underground karst cave 20 are determined by relying on the analyzer 103.

[0027] Embodiment 2: As Figures 3 to 8 shown, in an embodiment of the present invention, for a sectional grouting detection device based on geological exploration, on the basis of Embodiment 1, a bottom frame seat 111 is provided at the bottom of the small multi-functional bit 11. Bottom shaft frames 112 are provided on both sides of the bottom frame seat 111. The bottom of the second grouting pipe 12 is connected to the bottom frame seat 111. Grouting ports 121 are provided on both sides of the bottom of the second grouting pipe 12.

[0028] As Figures 6 to 9 shown, a blocking shaft frame 113 is provided inside the small multi-functional bit 11. The blocking shaft frame 113 is slidably sleeved outside the second grouting pipe 12. The blocking shaft frame 113 can block the grouting port 121.

[0029] As shown Figures 6 to 14 As shown, micro sliders 91 are installed on both sides of the bottom of the through small hollow shaft 96. A third driving motor 92 is provided on the upper part of the micro slider 91. The output end of the third driving motor 92 is connected to a second lead screw 93. A second slider 94 is sleeved on the second lead screw 93. A connecting frame 95 is provided at the front end of the second slider 94. The bottom of the connecting frame 95 is connected to the shaft blocking frame 113.

[0030] Furthermore, when the small multi-functional drill bit 11 drills into the karst cave, the first driving motor 41 and the second driving motor 5 stop working synchronously. The third driving motor 92 is started. The second slider 94 moves upward along the second lead screw 93 to take the shaft blocking frame 113 out of the small multi-functional drill bit 11 and into the through small hollow shaft 96. Then the gas pump 6 is started, and the gas in the karst 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 collecting pipe 61. The extracted gas is recycled and processed for utilization, reducing energy consumption. And the pressure in the karst cave 20 becomes smaller after the gas is discharged.

[0031] Furthermore, after the gas is discharged, it is connected to an external grouting device through the grouting pipe connection port 71. The grouting device is started, and the karst cave 20 is grouted through the first grouting pipe 7, the second grouting pipe 12 and the grouting port 121. At the same time, the sleeve valves 16 in each other karst cave 20 are pushed open by the slurry, and grouting starts synchronously.

[0032] Working principle: Transport the equipment to the drilling position at the construction site. During use, two groups of first driving motors 41 are started synchronously. The first driving motor 41 drives the first lead screw 42 to rotate. The first lead screw 42 drives the first slider 43 to move downward. The first slider 43 drives the second driving motor 5 to move downward. A drilling channel 19 is formed during the downward drilling process. And the first anti-vibration spring frames 13 on both sides and the second anti-vibration spring frame 14 on the inner side damp the driving slider 4 to prevent the drilling from deviating from the position.

[0033] During operation, the drilling bit 8 and the small multi-functional drill bit 11 are connected together to work synchronously. During the drilling operation, the shaft blocking frame 113 is 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 first enters the ground, 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 and receives the reflected waves formed by the elastic incident ultrasonic waves under the action of the geological structure of the soil layer, 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 combining the small multi-functional drill bit 11 with the ultrasonic radar exploration module 10 is realized, and the ultrasonic radar exploration module 10 is brought underground during the drilling process to pre-judge and analyze the karst rock formation.

[0034] 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 synchronously, the third drive motor 92 starts, and the second slide 94 moves upward along the second lead screw 93 to take out the plug shaft frame 113 from the small multi-functional drill bit 11 and into the through small hollow shaft 96. Then, the gas extraction pump 6 starts, and the gas in the karst 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 extraction pipe 61. The extracted gas is recycled and processed for utilization, reducing energy consumption. Moreover, as the gas in the karst cave 20 is discharged, the pressure becomes smaller.

[0035] After the gas is discharged, it is connected to an external grouting device through the grouting pipe connection port 71. The grouting device is started, and the karst cave 20 is grouted 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 slurry, and grouting starts synchronously.

[0036] In summary, the operation process can be simplified from the original detection, drilling, rod withdrawal, changing to a small drill bit, rod advancement for drilling, rod withdrawal, gas extraction, grouting filling, etc. to detection, drilling, gas extraction, drilling, gas extraction, grouting filling, etc. In this way, it is possible to integrate detection, drilling, gas extraction, and grouting without rod withdrawal. At the same time, by replacing multiple groutings with a one-time grouting, the operation efficiency is improved, energy is saved, and energy consumption is reduced. Moreover, after the collected and recycled gas is processed, it can be used as a new energy source, which is energy-saving and environmentally friendly.

[0037] Embodiment 3: This embodiment provides a sectional grouting detection device based on geological exploration and its usage method as described in Embodiment 1 or Embodiment 2, and the steps are as follows: S1. The equipment is transported to the position of the drill hole at the construction site and starts working. The drill bit 8 and the small multi-functional drill bit 11 are connected together to work synchronously to form a drill hole 19. The small multi-functional drill bit 11 first enters the foundation, and the ultrasonic radar exploration module 10 starts working. The transmitter 101 in the ultrasonic radar exploration module 10 generates elastic incident ultrasonic waves to monitor, analyze and judge whether there is a karst cave 20, and record the position information; S2. When reaching the karst cave 20 area, the first drive motor 41 and the second drive motor 5 stop working synchronously. The plug shaft frame 113 is taken out from the small multi-functional drill bit 11 and into the through small hollow shaft 96. The gas extraction pump 6 starts, and the gas in the karst 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 extraction pipe 61. The extracted gas is recycled and processed for utilization, reducing energy consumption. Moreover, as the gas in the karst cave 20 is discharged, the pressure becomes smaller; S3. After the gas collection in the multi-karst cave area is completed, it is connected to an external grouting device through the grouting pipe connection port 71, and grouting operation is prepared; 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 valves 16 in each other karst cave 20 are pushed open by the grout, and grouting starts synchronously, so as to realize one-time grouting instead of step-by-step grouting for multiple karst caves 20, improve efficiency and reduce energy consumption.

10. A sectional grouting detection device based on geological exploration and its usage method as described in claim 9, characterized in that, It includes the following steps: S1. The equipment is transported to the drilling position at the construction site and starts operation. The drilling bit 8 and the small multi-functional drill bit 11 are connected together to synchronously form a drilling channel 19. The small multi-functional drill bit 11 first enters the foundation. The ultrasonic radar exploration module 10 starts operation. The transmitter 101 in the ultrasonic radar exploration module 10 generates elastic incident ultrasonic waves to monitor, analyze, and judge whether there is a karst cave 20, and record the position information. S2. When reaching the karst cave 20 area, the first driving motor 41 and the second driving motor 5 stop operating synchronously. The blocking shaft frame 113 is taken out of the small multi-functional drill bit 11 and enters the small hollow shaft 96.
