Description

Technical Field

[0001] The invention relates to the technical field of construction sampling and detection, in particular to a sampling device for detecting the construction quality of peat soil cement mixing piles. Background Art

[0002] As demands for project quality continue to rise, relevant industry standards and regulations are becoming increasingly stringent. Regarding the quality inspection of peat soil cement mixing piles, specific testing methods and acceptance criteria for various indicators, such as pile strength, integrity, and uniformity, are clearly defined. This requires that samples obtained by the sampling device accurately reflect the actual quality of the pile, ensuring the accuracy and reliability of the test results and providing a solid basis for determining project quality.

[0003] However, when sampling peat soil cement mixing piles, the sampling needs to be done to a certain depth and is affected by the underground environment, resulting in the sample being not formed and breaking, resulting in incomplete sampling. The broken samples are not easy to move in the hole, which affects the subsequent sampling work. Therefore, the present invention provides a sampling device for the construction quality inspection of peat soil cement mixing piles to alleviate the technical problem of incomplete sampling after the cement mixing piles are broken in the prior art. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem in the prior art that when sampling peat cement mixing piles, the samples are affected by the underground environment when sampling to a certain depth, resulting in the samples being not formed and broken, resulting in incomplete sampling, and the broken samples are difficult to move in the hole, affecting the subsequent sampling work. A sampling device for construction quality inspection of peat cement mixing piles is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A sampling device for detecting the construction quality of peat soil cement mixing piles comprises a base and a sampling sleeve, an annular groove is provided inside the sampling sleeve, a fixed ring is fixedly connected to the surface of the annular groove, a connecting column is slidably connected to the fixed ring, the connecting column passes through the clamping block and slides in the arc groove of the rotating ring, the rotating ring is meshed with a sensing rotating gear column, the sensing rotating gear column is arranged in a vertical groove provided inside the sampling sleeve, a sampling drill bit is fixedly connected to the side of the sampling sleeve away from the connecting plate, the connecting plate is rotatably connected to an on-board motor, the output end of the on-board motor is fixedly connected to an on-board gear, the on-board gear is meshed with a meshing gear ring, and a sampling sleeve is provided on the inner wall of the meshing gear ring.

[0007] The above technical solution further includes:

[0008] A fixed block is fixedly connected to the base above, and the fixed block is rotatably connected to an on-base motor. The on-base motor is fixed to one side of a second bevel gear, which is meshed with a first bevel gear. A threaded rod is fixedly connected to the top of the first bevel gear, and the threaded rod is threadedly connected to a connecting plate. The fixed ring has an inclined groove on its surface, and the connecting post slides within the groove. The connecting post is fixedly connected to the clamping block, and the rotating ring is rotatably connected to the annular groove. The first bevel gear is rotatably connected to the base. The cooperation between the inclined groove and the connecting post can convert the rotation of the rotating ring into linear sliding of the connecting post along the inclined groove, thereby driving the clamping block toward or away from the center, achieving precise clamping of the bottom of the sampling pile. The annular groove provides stable rotational support for the rotating ring, ensuring its smooth operation. The rotatable connection of the first bevel gear to the base makes power transmission more stable, ensuring the consistency and reliability of the entire sampling operation, and facilitating the smooth and complete removal of the sampling pile.

[0009] The side surface of the fixing block is fixedly connected with a control body, a display screen is arranged above the control body, and pull rods are arranged on both sides of the fixing block.

[0010] A vertical corner plate is fixedly connected to the top of the base, and the vertical corner plate is slidably connected to the connecting plate. The vertical corner plate guides and supports the vertical connecting plate, so that the connecting plate can slide up and down smoothly and accurately under the drive of the threaded rod, ensuring that the sampling sleeve remains vertical during the drilling process to avoid deviation, thereby improving the accuracy of sampling and ensuring that the samples taken can truly reflect the quality of the pile body. The stepped locking structure of the bottom sealing device can synchronously block the drill cuttings falling channel during the sampling process.

[0011] A square notch is provided on the surface of the base, which is used for sampling peat soil cement mixing piles. The square notch provides a precise positioning area for sampling. When sampling, the operator can quickly align the sampling device with the pile body to avoid sampling position deviation. At the same time, it can also protect the soil around the pile body to a certain extent, reduce the impact on the surrounding environment, and ensure the smooth progress of the sampling work.

[0012] A storage water tank is fixedly connected above the base, a water supply pump is provided inside the storage water tank, a water level monitor is provided at the bottom of the water supply pump, a water supply port is provided on the side of the storage water tank, and the water supply port is used to connect to the bottom of the connecting plate to supply water to the side wall of the sampling sleeve.

[0013] The base is equipped with multiple sets of lifting columns for supporting the base during sampling, and is also equipped with rollers for moving the base. The base is equipped with multiple sets of lifting columns for supporting the base during sampling, and is also equipped with rollers for moving the base. This design evenly distributes the overall weight of the device. The combination of rollers and lifting columns allows the device to be easily moved by a single person. Its portability and compactness significantly surpass those of traditional large-scale drilling machines, making it particularly suitable for flexible operations in narrow construction sites.

[0014] The water storage tank, with a cover plate above, provides a stable water source for the sampling process. A water supply pump delivers pressurized water to the sidewalls of the sampling sleeve. A water level monitor monitors the tank level in real time to ensure a continuous water supply. This water supply to the sidewalls of the sampling sleeve lubricates and reduces dust during drilling, reducing drilling resistance, protecting the sampling drill bit, and extending its service life. It also reduces the risk of dust to the environment and operators.

[0015] A camera is provided at the bottom of the base, and the camera at the bottom of the base is used to detect the position of the sampling drill bit during drilling.

[0016] Multiple groups of clamping blocks for clamping samples are arranged between the fixed ring and the rotating ring. The device achieves a certain clamping accuracy through the precise coordination of the inclined slot transmission and the bevel gear set.

[0017] The present invention has the following beneficial effects:

[0018] 1. In the present invention, after drilling is completed, the closed structure inside the sleeve can be quickly activated to tightly wrap the sample to prevent the sample from being broken or falling off due to shaking, collision and other factors during the lifting process, ensuring that the sample taken out from the peat soil cement mixing pile is intact, providing a reliable basis for subsequent accurate detection of pile quality.

[0019] 2. In the present invention, when downward sampling is performed using the sampling sleeve and the threaded sleeve, the sampling length can be increased. After the sampling is completed, the clamping block at the bottom will block the bottom, thereby completing the sampling inside the sleeve and achieving a one-time complete sampling effect.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings.

[0031] In one embodiment, for the above-mentioned inclined groove 23, a fixed block 8 is fixedly connected above the base 1, and the fixed block 8 is rotatably connected to the base motor 9, which is fixed on one side of the second bevel gear 5. The second bevel gear 5 is meshed with the first bevel gear 4, and a threaded rod 6 is fixedly connected above the first bevel gear 4. The threaded rod 6 is threadedly connected to the connecting plate 15, and the first bevel gear 4 is rotatably connected to the base 1.

[0032] In this embodiment, the coordination between the chute 23 and the connecting post 24 converts the rotation of the rotating ring 26 into linear sliding of the connecting post 24 along the chute 23, thereby driving the clamping block 25 toward or away from the center, achieving precise clamping of the bottom of the sampling pile. The annular groove 30 provides stable rotational support for the rotating ring 26, ensuring its smooth operation. The first bevel gear 4 is rotatably connected to the base 1, making power transmission more stable, ensuring the consistency and reliability of the entire sampling operation, and facilitating the smooth completion of the entire sampling pile removal operation.

[0033] In one embodiment, for the above-mentioned control body 7 , the side of the fixing block 8 is fixedly connected to the control body 7 , a display screen is provided above the control body 7 , and pull rods are provided on both sides of the fixing block 8 .

[0034] In one embodiment, for the above-mentioned vertical corner plate 3 , the vertical corner plate 3 is fixedly connected to the top of the base 1 , and the vertical corner plate 3 is slidably connected to the connecting plate 15 .

[0035] In this embodiment, the vertical corner plate 3 guides and supports the vertical connecting plate 15, so that the connecting plate 15 can slide up and down smoothly and accurately under the drive of the threaded rod 6, ensuring that the sampling sleeve 19 remains vertical during the drilling process to avoid deviation, thereby improving the accuracy of sampling and ensuring that the samples taken can truly reflect the quality of the pile.

[0036] In one embodiment, for the base 1 , a square notch 2 is provided on the surface of the base 1 , and the square notch 2 is used for sampling the peat soil cement mixing pile.

[0037] In this embodiment, the square notch 2 provides a precise positioning area for sampling. When sampling, the operator can quickly align the sampling device with the pile body to avoid sampling position deviation. At the same time, it can also protect the soil around the pile body to a certain extent, reduce the impact on the surrounding environment, and ensure the smooth progress of the sampling work.

[0038] In one embodiment, for the above-mentioned storage water tank 12, the storage water tank 12 is fixedly connected above the base 1, a water supply pump 13 is provided inside the storage water tank 12, a water level monitor 14 is provided at the bottom of the water supply pump 13, and a water supply port 21 is provided on the side of the storage water tank 12.

[0039] In this embodiment, a water storage tank 12 provides a stable water source for the sampling process, and a water supply pump 13 delivers pressurized water to the sidewalls of the sampling sleeve 19. A water level monitor 14 monitors the water level in the tank in real time to ensure a continuous water supply. The water supply to the sidewalls of the sampling sleeve 19 lubricates and reduces dust during drilling, reducing drilling resistance, protecting the sampling drill bit 20, and extending its service life.

[0040] In one embodiment, for the above-mentioned roller 10 , a plurality of lifting columns 11 for supporting the base 1 during sampling are provided at the bottom of the base 1 , and a roller 10 is provided at the bottom of the base 1 for moving the base 1 .

[0041] In this embodiment, the rollers 10 facilitate flexible movement of the equipment at the construction site, allowing it to quickly reach various sampling points. During sampling, raising the lifting column 11 securely supports the base 1, keeping it stable during the drilling process. This prevents sampling deviations or failures caused by equipment shaking, thereby improving the adaptability of the equipment and operational stability.

[0042] In one embodiment, for the above-mentioned water storage tank 12 , a cover plate is provided above the water storage tank 12 .

[0043] In one embodiment, for the base 1 , a camera is provided at the bottom of the base 1 , and the camera at the bottom of the base 1 is used to detect the position of the sampling drill bit 20 during drilling.

[0044] In one embodiment, for the clamping blocks 25 , multiple groups of clamping blocks 25 for clamping samples are provided between the fixed ring 22 and the rotating ring 26 .

[0045] The present invention is a sampling device for the construction quality inspection of peat soil cement mixing piles. The working principle is to first dig a sedimentation tank near the hole to be drilled, and then connect the water pipe to the position of the water supply port 21, and then Figure 1 A portion of the upper portion of the middle sampling sleeve 19 extends inward, so as to be used for secondary use after overflowing from the borehole into the sedimentation tank for sedimentation in the subsequent drilling step.

[0046] Then the user checks whether the key connection parts of each part are normal, and then fills the water storage tank 12 with water, and then turns on the control body 7 to detect whether the water level is normal. Then, the control body 7 is used to control the lifting column 11 to extend so that the roller 10 is off the ground, and then the control body 7 is used to control the motor 16 on the board to rotate. The output end of the motor 16 on the board drives the gear 17 on the board to rotate. The rotation of the gear 17 on the board will mesh with the meshing gear ring 18. The meshing gear ring 18 and the connecting plate 15 rotate and then drive the sampling sleeve 19 to rotate. The sampling sleeve 19 is in a clamped state at this time. If drilling continues downward, the threaded sleeve 31 and the sampling sleeve 19 are threadedly connected to form a whole sampling sleeve. At this time, the meshing gear ring 18 is fixed on the threaded sleeve 31 so as to rotate, and the rotation direction is opposite to the thread direction, so as to ensure that the sampling sleeve and the threaded sleeve 31 are separated during the rotation. After the sampling sleeve 19 rotates, water will be sprayed from the spray pipe connected to the bottom of the connecting plate 15 to the side of the sampling sleeve 19, and then the sampling sleeve 19 will follow the side wall to slide to the drilling position during the drilling process, so as to prevent damage to the surrounding materials of the sampling ground during sampling.

[0047] Then, by controlling the motor 9 on the seat, the rotation of the motor 9 on the seat will drive the second bevel gear 5 to rotate, and the second bevel gear 5 will mesh with the first bevel gear 4 when it rotates. The rotation of the first bevel gear 4 will drive the upper threaded rod 6 to rotate, and the rotation of the threaded rod 6 will cause the connecting plate 15 to drop. Then, as the motor 9 on the seat is started, the sampling sleeve 19 will use the sampling drill bit 20 to start drilling continuously to the sampling depth. As the drilling depth continues to increase, the peat soil cement mixing pile sampled will form a longer column. As the sampling drill bit 20 continues to move downward until it drills to the required position, the peat soil cement mixing pile wrapped by the sampling sleeve 19 is limited, and it has reached the required position at this time. Then, the control body 7 is used to control the sensing rotating gear column 28 to rotate. The rotation of the sensing rotating gear column 28 will mesh with the side wall of the rotating ring 26, so that the rotating ring 26 pushes the connecting column 24 to slide inside the arc groove 27.

[0048] At the same time, the connecting column 24 slides in the inclined groove 23 of the fixed ring 22, so that the multiple groups of clamping blocks 25 are gathered near the center position. At this time, since a part of the peat soil cement mixing pile is wrapped inside the sampling sleeve 19, the clamping block 25 just clamps the bottom of the sampling pile at the deepest part of the sampling point. Then the sampling sleeve 19 is stopped from rotating. At this time, the motor 9 on the seat is rotated in the reverse direction. The sampling material inside the sampling sleeve 19 is directly taken out together with the entire sampling pile, completing the sampling purpose, thereby realizing the overall removal of the sampling pile, reducing the number of sampling times and saving a lot of time.

[0049] As drilling continues to go deeper, the threaded sleeve 31 is threadedly connected to the sampling sleeve 19, and then the threaded sleeve 31 is fixed on the inner wall of the meshing gear ring 18 to continue drilling. At this time, the water pipe needs to be detached from the original sampling sleeve 19 and moved to the hole above the threaded sleeve 31 to continue to be used for secondary use by water flow sedimentation.

[0050] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
