Description

Technical Field

[0001] The present invention relates to the technical field of burying pore pressure sensors, and in particular to a burying device for pore pressure sensors. Background Art

[0002] In the field of geotechnical engineering, whether it is on-site construction or scientific research, it is often necessary to conduct in-situ testing to obtain necessary evaluation indicators. Pore water pressure is an important observation indicator in geotechnical engineering. Pore water pressure gauges are often buried on site to judge the soil reinforcement effect, study the change law of soil strength, and analyze the soil consolidation state based on the observation results.

[0003] Announcement No. CN217438870U discloses a pore water pressure sensor embedding device, which inserts the hoop claw from the bottom of the pore water pressure sensor so that the ring of the hoop claw is placed under the limit hoop, and the pore water pressure sensor with the hoop claw installed is placed at the hole to be installed to see whether the hoop claw can lock itself in the hole. If not, it is necessary to manually bend the opening angle of the hoop claw until it can be locked in the hole. The top connecting sleeve is put on the top of the pore water pressure sensor, and the top connecting sleeve is connected to the bottom of the drill pipe, and the drill pipe is lowered. When the pore water pressure sensor is lowered to the target point, the lowering is stopped, and the pore water pressure sensor is connected to the acquisition instrument to see whether the pore water pressure sensor can work normally. If normal, the next step is carried out. If the pore water pressure sensor cannot work normally, the pore water pressure sensor is damaged during the lowering process and needs to be removed and a new pore water pressure sensor is reinstalled. However, the following problems still exist in the actual use of this patent: Although the pore water pressure sensor embedding device can realize the installation of the pore water pressure sensor, it is necessary to drill a hole before installing the pore water pressure sensor. It is not possible to drill a hole of corresponding depth according to the embedding height, which is not conducive to installing the pore water pressure sensor to the specified depth for water pressure detection. At the same time, the ring clamp claw needs to be unfolded by manual adjustment during installation, which is not only cumbersome to operate, but also not suitable for holes with deeper depths. At the same time, once the ring clamp claw is inserted into the soil, it is not convenient to retract the ring clamp claw, and the pore water pressure sensor cannot be reused. In the existing technology, a hole of corresponding depth can be opened by a drill bit to install the pore water pressure sensor, but the debris and soil in the hole cannot be cleaned in time during drilling, which affects the drilling effect. At the same time, it is not convenient to clean the hole and the surrounding area after drilling, which affects the installation effect of the pore water pressure sensor.

[0024] Working principle: Before using this buried device for pore pressure sensor, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 11 As shown, first, the first rotating motor 103 is used to drive the first rotating worm 104 to rotate, and the first rotating worm 104 and the first rotating worm wheel 105 are meshed and connected, so that the first rotating worm wheel 105 drives the drilling conveying cylinder 108 to rotate, and the drilling conveying cylinder 108 drives the first mounting ring 114 and the drilling teeth 115 to rotate, and the drilling teeth 115 are used to perform preliminary drilling, and at the same time, the clamping motor 119 is started to drive the first bevel gear 120 to rotate, and the meshing connection between the first bevel gear 120 and the second bevel gear 121 is used to make the second bevel gear 121 drive the clamping threaded rod 122 to rotate, and at the same time, the clamping threaded sleeve 123 drives the clamping threaded rod 122 to rotate. The sliding rod 124 and the clamping protrusion 125 are expanded and moved, and the characteristics of the clamping sliding rod 124 and the clamping protrusion 125 being engaged with the fixing groove 126 are utilized to make the first mounting seat 127 drive the drilling drill bit 128 to rotate, and the drilling drill bit 128 is used for secondary drilling, thereby improving the drilling efficiency, and by starting the conveying motor 111 to drive the conveying rotating rod 112 and the conveying spiral blade 113 to rotate, and utilizing the structural characteristics of the conveying spiral blade 113, the soil and stones generated by the drilling are conveyed to the collection box 106, and the cleaning scraper 110 is driven to rotate by the drilling conveying cylinder 108, so that the conveyed soil and stones can be collected and discharged through the sewage valve 107.

[0025] Secondly, the burying mobile vehicle 201 is used to move the entire device, and the second rotating motor 204 is started to drive the second rotating worm 205 to rotate. The second rotating worm 205 is engaged with the second rotating worm gear 206, so that the second rotating worm gear 206 drives the rotating connecting block 207 and the connecting bracket 208 to rotate. After the drilling drill bit 128 is used to drill the hole, the drilling drill bit 128 is moved to the top of the burying mobile vehicle 201, and the second rotating motor 204 is used to move the drill bit placement rack 217 to the top of the drilling drill bit 128. The clamping sliding rod 124 and the clamping protrusion 125 are driven to retract by the clamping motor 119. When the clamping sliding rod 124 and the clamping protrusion 125 are separated from the first mounting seat 127, the drilling drill bit 128 falls into the drill bit placement rack 217, and the cleaning placement rack 218 is moved to the bottom of the clamping bracket 118 by the second rotating motor 204. The clamping motor 119 is started to drive the clamping When the sliding rod 124 and the clamping protrusion 125 are unfolded, when the clamping sliding rod 124 and the clamping protrusion 125 are engaged with the mounting slot 220 inside the second mounting seat 219, the connection between the clamping bracket 118 and the second mounting seat 219 is realized. At the same time, the unfolding motor 222 is started to drive the unfolding main gear 223 to rotate. By utilizing the meshing connection between the unfolding main gear 223 and the meshing gear 224, the meshing gear 224 drives the meshing gear ring 225 to rotate. By utilizing the meshing connection between the meshing gear ring 225 and the driven gear 226, the driven gear 226 drives the rotating block 227 and the spiral cleaning blade 228 to rotate. By changing the rotation angle of the spiral cleaning blade 228, the extension of the spiral cleaning blade 228 is achieved, which can not only clean the inside of the drill hole, but also clean the surface of the drill hole, preventing mud and stones from falling into the inside of the hole, thereby affecting the installation and detection effect of the pore water pressure sensor 210. Finally, when the hole is cleaned, the second mounting seat 219 is placed on the cleaning placement rack 218. At the same time, the fixed magnet 215 is magnetically connected to the iron block inside the fixed groove 126 to realize the top installation of the telescopic rod 213. The second mounting ring 211 is installed to the bottom of the clamping bracket 118 and penetrates into the corresponding depth of the hole. By starting the clamping motor 119, the clamping sliding rod 124 drives the clamping protrusion 125 to expand, and the fixed magnet 215 drives the sliding limit block 214 and the installation telescopic rod 213 to slide relative to each other inside the second mounting ring 211 in the fixed groove 126. The fixing nail 216 can be used to achieve the installation and fixation of the entire second mounting ring 211, thereby improving the installation stability of the pore water pressure sensor 210 and avoiding the phenomenon that the pore water pressure sensor 210 causes errors in the detection data due to unstable installation. By starting the upgrade motor 230 to drive the lifting rotation rod 231 and the bevel gear transmission assembly 232 to rotate, the bevel gear transmission assembly 232 drives the lifting threaded rod 233 to rotate, and at the same time the lifting threaded sleeve 234 drives the fixing ring 101 to move up and down, which can not only realize the control of the drilling depth, but also facilitate the accurate installation of the pore water pressure sensor 210.
