Description

Technical Field

[0001] The invention relates to the technical field of drilling sampling, in particular to a portable underground tunnel surrounding rock core drilling monitoring sampling device and a use method thereof. Background Art

[0002] Rock mass quality is a prerequisite for evaluating geological conditions. Therefore, it is crucial to accurately obtain the rock mass mechanical parameters and internal geological structure characteristics of the surrounding rock (especially the fracture structure surface and other stability and permeability-controlling geological structures in the rock mass). On-site in-situ drilling sampling is an important means to understand the internal rock mass structural characteristics of the surrounding rock.

[0003] The geological conditions of underground space are complex, the spatial distribution is limited, and the exposed surrounding rock surface has a complex geometric structure, which brings challenges to the efficient and safe sampling of surrounding rocks in narrow spaces. At present, the existing rock field in-situ sampling equipment can only drill holes in one direction (vertically inward), and the distribution of fracture structure surfaces in the surrounding rock is complex. Drilling machines that can only drill in a single direction cannot accurately reveal the geological structure information of the stability and permeability control structure surface inside the surrounding rock; in addition, the existing drilling sampling equipment often has a large size and weight, which increases the difficulty of using it in unfavorable geological conditions in narrow spaces.

[0004] During the drilling process, the drilling rig will inevitably generate torque and vibration due to the shaking of the drilling rig, the rotation of the drill rod, and the friction between the drill bit and the rock contact surface, which can easily cause damage to the core and affect the integrity of the drilled surrounding rock core. In addition, during the drilling process of the drilling rig, the location of the fracture structure surface inside the rock mass is unknown. The use of drilling parameters suitable for the intact surrounding rock will lead to fracture and damage of the fracture structure surface in the sampled core, and the original location and integrity of the core containing the fracture structure surface cannot be guaranteed, which seriously affects the objective and accurate understanding of the physical mechanics and hydraulics of the fracture structure surface that controls stability and seepage. How to perceive the changes in the lithology of the surrounding rock during the drilling process of a drilling rig in a complex engineering geological field, to provide real-time feedback and adjust the drilling parameters, and to ensure the in-situ and complete sampling of the surrounding rock core (especially the rock mass with fractured structural surfaces) is still a key challenge in the evaluation of the suitability of the development and utilization of underground space repositories. At the same time, the traditional drilling sampling process cannot properly handle the wastewater discharged from the borehole. After the sampling is completed, the sample cannot be quickly removed from the sampling rod, and the operation is cumbersome and inconvenient to use. Summary of the invention

[0016] The method for using the portable underground tunnel surrounding rock core drilling monitoring sampling device comprises the following steps:

[0017] S1. First, select the construction location, then place the mounting plate on one side of the construction surface and use expansion bolts to fix the mounting plate on one side of the construction surface, leaving an operating space between the mounting plate and the construction surface. After the installation is completed, the operator drives the mounting seat to move horizontally through the displacement adjustment component to achieve horizontal adjustment of the drilling position, and at the same time drives the mounting rod to rotate by rotating the gear turntable to achieve adjustment of the drilling direction;

[0018] S2, then use the driving assembly to drive the drilling machine on one side of the installation sleeve to move close to the rock layer, and start the drilling machine to drive the drill rod and the drill bit to rotate, so as to achieve drilling and sampling of the rock layer, and at the same time, one side of the wastewater recovery assembly is in contact with the drilling position;

[0019] S3. During the drilling sampling process, the operator uses an external computer to analyze the specific parameter information about the rock formation transmitted by the integrated sensor, and then adjusts the drilling parameters in real time during the drilling process based on the feedback parameter information, thereby achieving fidelity sampling. After the sampling is completed, the drive assembly is adjusted in reverse to remove the drill bit and drill rod. The drill bit is removed and the removed core is taken out by the unloading assembly, and then the rock formation analysis is carried out.

[0020] The invention has the following advantages: when in use, the operator first fixes the mounting plate on the surrounding rock with expansion screws according to the target target area of ​​the surrounding rock to be studied, and then, according to the (occurrence) distribution of the potential fracture structure surface inside the surrounding rock, first rotates the position adjustment rod to drive the mounting seat to move, thereby realizing the lateral adjustment of the drilling position, then pulls out the positioning column, adjusts the gear turntable to adjust the drilling angle of the drill bit on one side of the mounting rod, and then starts the drilling machine to drive the drill bit at one end of the drill rod to rotate, and at the same time, the operator inserts the tool rod into the jack of the torsion column to drive the torsion column to rotate, and drives the mounting sleeve to move laterally along the mounting rod under the action of the adjusting gear and the transmission gear rod to perform drilling, and at the same time, the operator makes the wastewater recovery frame contact with the rock surface and then rotates the threaded rod to drive the transmission column to rotate, and the transmission column squeezes the pressing block to fix the wastewater recovery frame under the action of the telescopic member, and when the water valve is opened to cool the drill bit during the drilling process, the wastewater recovery frame can effectively collect wastewater and filter it under the action of the filter screen, so as to achieve better environmental protection effect;

[0021] At the same time, during the drilling process, the sample will enter the drill pipe through the hollow position of the drill bit to achieve sampling. At the same time, during the drilling sampling process, the integrated sensor can measure the drilling speed, torque, and thrust applied to the drill pipe by the drilling rig. At the same time, under the action of the laser displacement sensor, the laser displacement sensor can measure the precise displacement of the contact between the drill bit and the rock surface before each drilling and each drilling rig starts drilling through the hollow borehole. The integrated sensor transmits information to the computer through the data acquisition sensor to conduct real-time monitoring of the drilling machine parameters (drilling speed, torque, thrust) and drilling position during the drilling process.

After the sampling is completed, the drill rod is taken out and the drill bit is disassembled. The drill bit drives the unloading ring to move through the linkage rod on one side of the fixed sleeve to achieve rapid unloading. Compared with the traditional material extraction method, this method of the device is more convenient to operate and use, has better environmental protection effect, and can unload more conveniently. The condition of the rock formation can be judged in time according to the drilling information transmitted by the integrated sensor, and then the drilling parameters can be adjusted to achieve fidelity sampling.

[0039] Example 3, please refer to Figure 1-Figure 6The method for using the portable underground tunnel surrounding rock core drilling monitoring sampling device includes the following steps: S1, first select the construction position, then place the mounting plate 1 on one side of the construction surface and use expansion bolts to fix the mounting plate 1 on one side of the construction surface, and leave an operating space between the mounting plate 1 and the construction surface. After the installation is completed, the operator drives the mounting seat 2 to move horizontally through the displacement adjustment component to achieve the horizontal adjustment of the drilling position, and at the same time drives the mounting rod 15 to rotate by rotating the gear turntable 22 to achieve the adjustment of the drilling direction;

[0041] S3. During the drilling sampling process, the operator uses an external computer to analyze the specific parameter information about the rock formation transmitted by the integrated sensor 6, and then adjusts the drilling parameters in real time during the drilling process according to the feedback parameter information, thereby achieving fidelity sampling. After the sampling is completed, the drive assembly is adjusted in reverse to remove the drill bit 27 and the drill rod 9. The drill bit 27 is disassembled and the removed core is taken out by the action of the unloading assembly, and then the rock formation analysis is carried out.

[0042] Example 4, please refer to Figure 1-Figure 6 When using it, the operator first fixes the mounting plate 1 on the surrounding rock with expansion screws according to the target area of ​​the surrounding rock to be studied, and then according to the occurrence and distribution of the potential fracture structure surface inside the surrounding rock, first rotate the position adjustment rod 17 to drive the mounting seat 2 to move, thereby realizing the lateral adjustment of the drilling position, and then pull out the positioning column 24, adjust the gear turntable 22 to adjust the drilling angle of the drill bit 27 on one side of the mounting rod 15, and then start the drilling machine 4 to drive the drill bit 27 at one end of the drill rod 9 to rotate, and at the same time the operator uses the tool rod to insert the socket 2 of the torsion column 7 8 drives the torsion column 7 to rotate, and under the action of the adjusting gear 33 and the transmission gear rod 8, the installation sleeve 3 is driven to move horizontally along the installation rod 15 to perform drilling. At the same time, the operator makes the wastewater recovery frame 14 contact the rock surface and then rotates the threaded rod 10 to drive the transmission column 12 to rotate. The transmission column 12 squeezes the pressing block 36 to fix the wastewater recovery frame 14 under the action of the telescopic member 37. When the water valve is opened to cool the drill bit 27 during the drilling process, the wastewater recovery frame 14 can effectively collect wastewater and filter it under the action of the filter screen 32, so that the environmental protection effect is better.

[0043] At the same time, during the drilling process, the sample will enter the drill rod 9 through the hollow position of the drill bit 27 to achieve sampling. At the same time, during the drilling sampling process, the integrated sensor 6 can measure the drilling speed, torque, and thrust applied to the drill rod 9 by the drilling machine 4. At the same time, under the action of the laser displacement sensor 34, the laser displacement sensor 34 can measure the precise displacement of the contact between the drill bit 27 and the rock surface each time drilling and each time before the drilling machine 4 starts drilling through the hollow borehole. The integrated sensor 6 transmits information to the computer through the data acquisition sensor 5, and performs real-time monitoring of the drilling machine 4 parameters such as drilling speed, torque, thrust and drilling position during drilling. The operator uses an external computer to analyze the specific parameter information about the rock formation transmitted by the integrated sensor 6, and then adjusts the drilling parameters in real time during the drilling process according to the feedback parameter information, thereby realizing fidelity sampling. After the sampling is completed, the drill rod 9 is taken out and the drill bit 27 is disassembled. The drill bit 27 drives the unloading ring 29 to move through the linkage rod 30 on one side of the fixed sleeve 31 to realize rapid unloading. Compared with the traditional material collection method, this method of the device is more convenient to operate and use, has better environmental protection effect, and can unload more conveniently.
