Abstract
Description
A geotechnical engineering exploration device that can observe the depth of soil penetration. Technical Field
[0001] The embodiments disclosed herein relate to the field of soil and rock sampling technology, and more specifically, to a soil and rock engineering exploration device that allows for the observation of soil penetration depth. Background Technology
[0002] Geotechnical engineering investigation, as a key preliminary step in engineering construction, refers to the systematic investigation, analysis, and comprehensive evaluation of the geological structure, environmental characteristics, and geotechnical engineering conditions of the construction site based on the specific needs of the construction project, and the final formation of professional investigation documents. Its results are directly related to the scientific nature of subsequent engineering design, the safety and economy of construction, and play a decisive role in the success or failure of the entire construction project.
[0003] In the geotechnical engineering investigation process, borehole sampling is the core means of obtaining underground soil and rock samples and analyzing their physical and mechanical properties. Currently, the commonly used borehole sampling method in the industry mainly relies on the drilling rig to drive the drill bit to rotate at high speed and complete the drilling operation at the predetermined soil and rock sampling location through mechanical cutting action. However, this method lacks a real-time observation and precise control mechanism for the drilling depth, which means that operators can only rely on experience to judge the drilling depth. This can easily affect the richness and accuracy of the investigation data and reduce the guiding value of the investigation results for engineering design and construction. Summary of the Invention
[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a geotechnical engineering exploration device that can observe the depth of soil penetration, which solves the technical problem that the drilling method driven by the drilling rig makes it difficult to observe the depth of soil penetration, thus reducing the exploration effect.

[0027] As shown in Figures 1-4, a geotechnical engineering exploration device for observing soil penetration depth is illustrated in one embodiment of this disclosure. The device includes a frame 1, a pressure rod 2, a sampling paddle 3, an observation mechanism, and a protective mechanism. Multiple fixed cones 15 are fixedly connected to the bottom end of the frame 1. The pressure rod 2 is mounted inside the frame 1 via a lifting mechanism, which drives the pressure rod 2 to move up and down within the frame 1. The sampling paddle 3 is mounted at the bottom end of the pressure rod 2 via a rotating mechanism, which drives the sampling paddle 3 to rotate and collect samples. The observation mechanism is located on one side of the frame 1, enabling the observation of soil penetration depth. The protective mechanism is located on the frame. Inside 1, the soil carried out by the sampling paddle 3 is confined to the sampling paddle 3. The sampling paddle 3 is rotated by the rotating mechanism and lowered into the sampling position by the lifting mechanism to collect a sample. During this process, the soil penetration depth of the sampling paddle 3 is observed by the observation mechanism, and the soil carried out by the sampling paddle 3 is confined to the sampling paddle 3 by the protective mechanism. Through the cooperation between the pressure rod 2, the sampling paddle 3, the rotating mechanism, the lifting mechanism, the observation mechanism and the protective mechanism, it is convenient to observe the soil penetration depth, improve the exploration effect and enhance the guiding value of the exploration results for engineering design and construction.
[0028] The lifting mechanism includes: a slide rod 4, a drive screw 5, and a drive assembly. The slide rod 4 is fixedly connected to the top of the pressure rod 2. A sliding hole is provided on the frame 1, and the slide rod 4 is slidably connected in the sliding hole. The drive screw 5 is fixedly connected to the top of the pressure rod 2. The drive assembly is located inside the frame 1 and is used to drive the pressure rod 2 and the slide rod 4 to move up and down. The drive assembly includes: a rotating gear 6, a drive gear 7, and a first motor 8. The rotating gear 6 is rotatably connected to the top of the frame 1 and has a screw hole. The drive screw 5 is threaded into the screw hole. The drive gear 7 is rotatably connected to the top of the frame 1. Wheel 7 meshes with rotating gear 6. First motor 8 is installed on the inner top wall of frame 1. The output end of first motor 8 passes through frame 1 and is fixedly connected to drive gear 7. Drive gear 7 is driven to rotate by first motor 8 installed on frame 1. When drive gear 7 rotates, it drives rotating gear 6 to rotate. When rotating gear 6 rotates, drive screw 5 moves in the screw hole opened on drive gear 7, thereby driving pressure rod 2 to descend. When pressure rod 2 descends, slide rod 4 slides in the slide hole opened on frame 1, thereby increasing the stability of pressure rod 2 when sliding, thereby driving sampling paddle 3 to descend and sample.
[0029] The rotating mechanism includes a rotating rod 9 and a second motor 10. The rotating rod 9 is rotatably connected to the bottom end of the pressure rod 2. The sampling paddle 3 is fixedly connected to the rotating rod 9. The second motor 10 is installed at the top end of the pressure rod 2. The output end of the second motor 10 passes through the pressure rod 2 and is fixedly connected to the top end of the rotating rod 9. The rotating rod 9 is driven to rotate by the second motor 10. When the rotating rod 9 rotates, it drives the sampling paddle 3 to rotate. The sampling paddle 3 is driven to descend and insert into the soil for rotational sampling by the pressure rod 2. During the sampling process, the soil will remain on the sampling paddle 3.
[0030] The observation mechanism includes a pointing frame 11 and a scale bar 12. The pointing frame 11 is fixedly connected to one end of the pressure rod 2. A sliding groove is provided on the frame 1, and the pointing frame 11 is slidably connected in the sliding groove. The scale bar 12 is fixedly connected to one side of the frame 1. When the pressure rod 2 is lowered, it will drive the pointing frame 11 to lower synchronously in the sliding groove. The scale bar 12 pointed to by the pointing frame 11 makes it easy for the operator to observe the depth of soil penetration more accurately.
[0031] The protective mechanism includes a protective plate 13 and a top plate 14. Both protective plates 13 are semi-circular and surround the sampling paddle 3. There are two protective plates 13. Two sliding grooves are opened on the frame 1. The two protective plates 13 are slidably connected in the two sliding grooves respectively. The pressure rod 2 is located between the two protective plates 13. The top plate 14 is fixedly connected to the top of the two protective plates 13. The sampling paddle 3 is covered by the two protective plates 13. When the sampling paddle 3 rises out of the hole after sampling, the soil brought out by the sampling paddle 3 is blocked by the protective plates 13, which makes it convenient for the operator to sample the soil at different depths.
[0032] Working principle: When soil and rock sampling is required, the frame 1 is placed at the sampling position. Then, multiple fixed cones 15 at the bottom of the frame 1 are driven into the ground. Next, two protective plates 13 are lowered into the chute until their bottom ends touch the ground. The second motor 10 then drives the rotating rod 9 to rotate, which in turn rotates the sampling paddle 3. During this process, the first motor 8 mounted on the frame 1 drives the drive gear 7 to rotate, which in turn drives the rotating gear 6. The rotating gear 6 causes the drive screw 5 to move within the screw hole on the drive gear 7, thereby lowering the pressure rod 2. As the pressure rod 2 descends, the sliding rod 4 slides within the sliding hole on the frame 1, increasing the stability of the pressure rod 2 during sliding. This causes the sampling paddle 3 to descend and take samples. During the descent of the pressure rod 2, the pointing frame 11 will descend synchronously within the chute. The scale bar 12 pointed to by the pointing frame 11 allows the operator to accurately observe the depth of soil penetration. After the soil and rock sampling is completed, the first motor 8 rotates in the opposite direction, thereby driving the drive gear 7 and the rotating gear 6 to rotate in the opposite direction, which in turn drives the drive screw 5 to rise, thereby driving the pressure rod 2 and the sampling paddle 3 to rise, thus bringing out the drilled soil. When the sampling paddle 3 rises, the protective plate 13 blocks the sampling paddle 3, thus blocking the soil and rock on the sampling paddle 3. After the sampling paddle 3 has completely risen outside the hole, the protective plate 13 is pulled up to expose the sampling paddle 3, making it convenient for the operator to sample soil and rock at different depths.
