Description
Technical Field
[0001] The utility model relates to the field of foundation detection auxiliary components, in particular to a soil sampling device used for foundation detection. Background Art
[0002] The foundation refers to the expanded part of the wall or column of the house that is based on the foundation buried underground. The design and inspection of the foundation is an important part of the work of construction engineers. Before the building design, it is necessary to conduct an engineering geological survey of the construction site and conduct physical and mechanical property tests on the foundation to make a correct evaluation of the engineering geological conditions of the site. This is a prerequisite for good design and construction. Therefore, my country has long clearly stipulated that no design can be made without a survey report, and no construction can be made without design drawings.
[0003] Specifically, in the process of foundation testing, it is necessary to sample the soil of the foundation, and then perform soil testing on the soil samples obtained by sampling. In this process, a soil sampling device is required to obtain soil samples at the foundation sampling position. The existing sampling device is usually a circular sampling cylinder with an open bottom, a connecting rod is vertically fixed at the top position, and a handle is designed on the top of the connecting rod. Specifically, during operation, the operator usually holds the handle and presses the circular sampling cylinder vertically downward to insert it into the foundation sampling position. This sampling method first The physical strength required of the operator is high, and a sufficiently large pressing force must be used to smoothly press the circular sampling cylinder into the foundation sampling position. At the same time, in the process of pulling out the cylinder after sampling, the soil sample in the circular sampling cylinder is easy to fall out during the lifting process, resulting in soil sampling failure. After the soil sample in the circular sampling cylinder is poured out, some soil samples will remain on the inner wall of the circular sampling cylinder. Since it is impossible to clean it thoroughly and conveniently, the residual samples will be mixed in during the next soil sampling, affecting the accuracy of the next sampling result.

The soil sampling operation is simple and easy to implement, as described below.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] Preferably, a plurality of inclined insertion holes are obliquely opened on the front outer portion of the soil-extracting sleeve, the plurality of inclined insertion holes are located in the same vertical direction, and the inclined insertion holes are coaxially penetrated by inclined insertion rods.
[0009] Preferably, the included angles between the axis of the oblique insertion hole and the horizontal plane are acute angles, the oblique insertion rod and the corresponding oblique insertion hole are coaxially clearance matched, and the outer ends of the oblique insertion rods are coaxially fixed with ends for easy holding.
[0010] Preferably, a scale indicating the vertical length dimension is printed on the periphery of the soil sampling sleeve.
[0011] Preferably, the driving assembly includes a stud and a bearing seat, the stud passes through the middle of the base plate in a vertical sliding fit, and the lower part of the stud passes through the matching hole in a threaded engagement manner, the bearing seat is fixed to the middle of the top surface of the base plate, the stud passes through the bearing seat coaxially and the stud is coaxially fixed to the inner ring of the bearing built into the bearing seat, the base plate is vertically provided with guide holes on both sides of the stud, the guide holes are coaxially slidably fitted with guide columns, the guide columns correspond to the wing plates respectively, and the bottom ends of the guide columns are fixed to the corresponding top surfaces of the wing plates through connecting sleeves.
[0012] Preferably, a rocker arm for rotating the stud with reduced effort is installed at the top end of the stud, and the stud is coaxially engaged with a locking nut at a position above the bearing seat.
[0013] Preferably, the bottom end of the stud extending into the soil-extracting sleeve is coaxially fixed with a push plate through a fixing sleeve, the bottom end surface of the push plate is higher than the bottom surface of the vertical plate, and the outer periphery of the push plate is coaxially slidably matched with the inner wall of the soil-extracting sleeve.
[0014] Preferably, the stud and the fixing sleeve are coaxially fixed by threaded cooperation, the guide column and the connecting sleeve are coaxially fixed by threaded cooperation, and an anti-dropping cap is coaxially fixed to the top end of the guide column.
[0015] Preferably, pedals are fixedly and horizontally extended outwards on the bottom surfaces of the vertical boards, and handles are fixedly and vertically extended on both edge positions of the top surfaces of the base boards.
[0016] When the soil sampling operation is performed at the foundation sampling position during foundation testing, all the oblique rods should be pulled out first, and then the soil sampling sleeve should be raised to the top end close to the bottom surface of the base plate. During operation, the locking nut should be screwed up close to the rocker arm, and then the rocker arm is held and the stud is driven to reverse counterclockwise. During the reversal process, the stud drives the soil sampling sleeve to rise vertically by engaging with the thread of the matching hole. During this process, the guide column can slide vertically along the guide hole to guide the vertical rise of the soil sampling sleeve, preventing the soil sampling sleeve from rotating circumferentially with the stud, and the rotation is stopped after the top end of the soil sampling sleeve is close to the bottom surface of the base plate. The stud lifts the base plate to the foundation sampling position and makes the soil sampling sleeve vertically aligned with the foundation sampling position, and then fixes the base plate, the driving assembly and the sampling assembly at the foundation sampling position by stepping on the pedal, and then holds the rocker arm again to drive the stud to rotate clockwise, and the stud drives the soil sampling sleeve to descend during the clockwise rotation until the bottom end of the soil sampling sleeve is pressed into the foundation sampling position, and rotates the stud to drive the soil sampling sleeve to continue to descend, and when the oblique plug hole at the lowest position is close to the ground, the oblique plug rod is inserted, so that the oblique plug rod inserted into the oblique plug hole can penetrate into the soil sample for reinforcement, and then continues to rotate the stud to drive the soil sampling sleeve to continue The soil sampling sleeve is then pulled upwards to allow the soil sample to be pulled out of the ground, and the soil sampling depth of the soil sample should be controlled with reference to the scale value of the scale ruler. After the soil sampling sleeve enters the ground to the required soil sampling depth, the forward rotation of the stud is stopped, and the stud is reversed counterclockwise again to drive the soil sampling sleeve to rise vertically and be pulled out. In this way, the forward and reverse rotation of the stud of the driving assembly can drive the soil sampling sleeve of the sampling assembly to rise and fall vertically, and then the soil sampling sleeve can be vertically pressed into the foundation sampling position to perform soil sampling operation, and after soil sampling is completed, the soil sampling sleeve can be vertically raised and pulled out, and the soil sampling operation method is simple and easy to implement. At the same time, since the soil sampling operation method of rotating the stud is replaced by the soil sampling operation method of pressing the soil sampling sleeve by a person, the physical requirements of the operator are reduced, which is conducive to ensuring the smooth completion of the soil sampling process. In the process of taking out the soil sample, the soil sampling sleeve can be driven to rise vertically along the stud by rotating the stud, so that the push plate can push out the soil sample in the soil sampling sleeve.At the same time, the push plate can be used to scrape and clean the inner wall of the soil extraction sleeve by coaxially sliding with the inner wall of the soil extraction sleeve, which ensures that the soil sample in the soil extraction sleeve can be smoothly and completely removed, and avoids residual soil sample adhering to the inner wall of the soil extraction sleeve.
[0017] The beneficial effects are as follows: 1. During sampling, the utility model fixes the base plate, the driving assembly and the sampling assembly at the foundation sampling position by a person stepping on the pedal, and then the soil taking sleeve of the sampling assembly can be driven to rise and fall vertically by the positive and negative rotation of the stud of the driving assembly, and then the soil taking sleeve can be vertically pressed into the foundation sampling position for soil taking operation, and after the soil taking is completed, the soil taking sleeve can be vertically raised and pulled out, and the soil taking operation mode is simple and easy to implement. At the same time, since the method of rotating the stud is used instead of the soil taking operation mode of the person applying force to press the soil taking sleeve, the physical requirements on the operator are reduced, which is conducive to ensuring the smooth completion of the soil taking process;
[0018] 2. When the soil sampling sleeve is vertically pressed into the foundation sampling position to collect soil, the oblique insertion rods are inserted into the soil sample in the soil sampling sleeve from the outside to the inside through the oblique insertion hole, so that the soil sample in the soil sampling sleeve can be reinforced with the help of the oblique insertion rods, and then the soil sample can be prevented from detaching from the soil sampling sleeve when the soil sampling sleeve is pulled upward after the soil sampling is completed, thereby avoiding the failure of soil sampling;
[0019] 3. In the process of taking out soil samples, the soil sampling sleeve can be driven to rise vertically along the stud by rotating the stud, so that the push plate can push out the soil sample in the soil sampling sleeve. At the same time, the push plate can be coaxially slidably matched with the inner wall of the soil sampling sleeve to scrape and clean the inner wall of the soil sampling sleeve with the help of the push plate, which ensures that the soil sample in the soil sampling sleeve can be taken out smoothly and completely, and avoids the residual soil sample adhering to the inner wall of the soil sampling sleeve.

[0033] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.
[0034] See also Figure 1-Figure 10As shown, the utility model provides a soil taking device for foundation detection, including a base plate 1 and a vertical plate 2, the base plate 1 is horizontally arranged in the transverse direction, and the vertical plates 2 are vertically fixed to both sides of the bottom surface of the base plate 1 in the longitudinal direction, and a driving component 4 is vertically inserted and installed in the middle of the base plate 1. Specifically, the driving component 4 includes a stud 407 and a bearing seat 406, the stud 407 passes through the middle of the base plate 1 in a vertical sliding fit, and the lower part of the stud 407 passes through the matching hole 503 in a threaded engagement manner, and the bearing seat 406 is fixed to the middle of the top surface of the base plate 1, the stud 407 coaxially passes through the bearing seat 406, and the stud 407 and the inner part of the bearing seat 406 are screwed together. The inner ring of the bearing is coaxially fixed, and the base plate 1 is vertically provided with guide holes 403 at both sides of the stud 407. The guide holes 403 are coaxially slidably matched with guide columns 402. The guide columns 402 correspond to the wing plates 501 respectively, and the bottom ends of the guide columns 402 are fixed to the top surfaces of the corresponding wing plates 501 through connecting sleeves 408. Such an arrangement facilitates the vertical lifting of the soil sampling sleeve 502 of the sampling assembly 5 by the forward and reverse rotation of the stud 407 of the driving assembly 4, so that the soil sampling sleeve 502 can be vertically pressed into the foundation sampling position for soil sampling operation, and the soil sampling sleeve 502 can be vertically lifted and pulled out after the soil sampling is completed.
[0035] See also Figure 1 one Figure 5 As shown, a sampling assembly 5 is installed at the bottom position of the driving assembly 4, which is used to drive the sampling assembly 5 to rise and fall vertically by applying force through the driving assembly 4 to complete the soil sampling operation. Specifically, the sampling assembly 5 includes a soil sampling sleeve 502 and a wing plate 501. The soil sampling sleeve 502 is a cylinder with an open bottom. A matching hole 503 is coaxially opened on the top surface of the soil sampling sleeve 502, and the driving assembly 4 is inserted through the matching hole 503. Both sides of the top of the soil sampling sleeve 502 are horizontally extended and fixed with wing plates 501, and the wing plates 501 are connected to the bottom of both sides of the driving assembly 4. This arrangement makes it easy to sample soil by pressing the soil sampling sleeve 502 into the foundation sampling position.
[0036] See also Figure 2-Figure 5As shown, the sampling assembly 5 has been further optimized, and a plurality of inclined holes 507 are obliquely opened on the front outer portion of the soil sampling sleeve 502, and the plurality of inclined holes 507 are located in the same vertical direction, and the inclined holes 507 are coaxially inserted with inclined rods 506. Such an arrangement makes it easy to reinforce the soil sample in the soil sampling sleeve 502 with the aid of the inclined rods 506, thereby preventing the soil sample from escaping from the soil sampling sleeve 502 when the soil sampling sleeve 502 is pulled upward after soil sampling is completed. The angle between the axis of the oblique insertion hole 507 and the horizontal plane is an acute angle, preferably between 20 and 45 degrees. This arrangement facilitates the oblique insertion rod 506 to smoothly enter the soil sample by obliquely penetrating when coaxially inserting the oblique insertion hole 507. The oblique insertion rod 506 and the corresponding oblique insertion hole 507 are coaxially matched with clearance, and the outer ends of the oblique insertion rod 506 are coaxially fixed with an end 505 for easy holding. This arrangement facilitates the oblique insertion rod 506 to smoothly pass through the oblique insertion hole 507, and at the same time, it is convenient to hold the oblique insertion rod 506 and apply force by setting the end 505. The outer periphery of the soil extraction sleeve 502 is printed with a scale 504 for indicating the vertical length dimension. This arrangement facilitates the soil extraction depth of the soil sample to be controlled by referring to the scale value of the scale 504.
[0037] See also Figure 2 one Figure 5 As shown, the drive component 4 is further optimized, and a rocker arm 404 for labor-saving rotation of the stud 407 is installed at the top of the stud 407. Preferably, the rocker arm 404 is L-shaped, and the stud 407 is coaxially engaged with a locking nut 405 above the bearing seat 406. Preferably, the locking nut 405 is a hand-tightened knurled nut. Such a configuration makes it easy to drive the stud 407 to rotate by applying force with the handheld rocker arm 404. At the same time, during daily restrictions, after tightening the locking nut 405 on the top surface of the bearing seat 406, the friction between the locking nut 405 and the top surface of the bearing seat 406 can prevent the stud 407 from rotating freely. The bottom end of the stud 407 extending into the soil-extracting sleeve 502 is coaxially fixed with a push plate 4010 through a fixing sleeve 409. The bottom end surface of the push plate 4010 is higher than the bottom surface of the vertical plate 2. Preferably, the bottom surface of the push plate 4010 is higher than the bottom surface of the pedal 3. At the same time, the axial length of the soil-extracting sleeve 502 is less than the length of the stud 407 extending out of the bottom surface of the base plate 1, so that the stud 407 has a sufficient axial length to drive the soil-extracting sleeve 502 to rise smoothly until it is completely out of the bottom surface and rises to the push plate 4010 to completely clear the soil sample in the soil-extracting sleeve 502. The outer periphery of the push plate 4010 is coaxially slidably matched with the inner wall of the soil-extracting sleeve 502. Such an arrangement makes it easy to scrape and clean the inner wall of the soil-extracting sleeve 502 by means of the push plate 4010 through the coaxial sliding match between the push plate 4010 and the inner wall of the soil-extracting sleeve 502.
[0038] Furthermore, the stud 407 and the fixing sleeve 409 are coaxially fixed by means of threaded matching, so that the stud 407 can be quickly assembled and disassembled with the push plate 4010 through the fixing sleeve 409, and the guide column 402 and the connecting sleeve 408 are coaxially fixed by means of threaded matching, and at the same time, it is convenient for the guide column 402 to be quickly assembled and disassembled with the wing plate 501 through the connecting sleeve 408, and the top of the guide column 402 is coaxially fixed with an anti-drop cap 401, and the purpose of such a setting is to prevent the top of the guide column 402 from sliding out of the guide hole 403 through the setting of the anti-drop cap 401. At the bottom surface of the vertical plate 2, the bottom surface of the vertical plate 2 is horizontally extended outward and fixed with a pedal 3, and the two edge positions of the top surface of the base plate 1 are vertically extended and fixed with a lifting handle 101. Such a setting is convenient for the operator to step on the pedal 3 to fix and prevent the base plate 1 from moving during the soil excavation process, and at the same time, it is convenient to lift and move the base plate 1 to change its position by setting the lifting handle 101.
[0039] When the soil sampling operation is performed at the foundation sampling position during foundation detection, all the inclined rods 506 should be pulled out at the beginning, and then the soil sampling sleeve 502 should be raised to the top close to the bottom surface of the base plate 1. During operation, the locking nut 405 should be screwed up close to the rocker arm 404, and then the rocker arm 404 is held and the stud 407 is driven to reverse counterclockwise. During the reversal process, the stud 407 drives the soil sampling sleeve 502 to rise vertically by means of threaded engagement with the matching hole 503. In this process, the guide column 402 can slide vertically along the guide hole 403 to guide the vertical rise of the soil sampling sleeve 502, preventing the soil sampling sleeve 502 from rotating circumferentially with the stud 407, and wait until the top of the soil sampling sleeve 502 is close to the bottom surface of the base plate 1. After the surface is formed, the rotation of the stud 407 is stopped, the base plate 1 is lifted and moved to the foundation sampling position and the soil sampling sleeve 502 is vertically compared with the foundation sampling position. Then, the base plate 1, the driving assembly 4 and the sampling assembly 5 are fixed at the foundation sampling position by stepping on the pedal 3. Then, the rocker arm 404 is held again to drive the stud 407 to rotate clockwise. During the clockwise rotation, the stud 407 drives the soil sampling sleeve 502 to descend until the bottom end of the soil sampling sleeve 502 is pressed into the foundation sampling position. The stud 407 is rotated to drive the soil sampling sleeve 502 to continue to descend. When the oblique plug hole 507 at the lowest position is close to the ground, the oblique plug rod 506 is inserted, so that the oblique plug rod 506 inserted into the oblique plug hole 507 penetrates into the soil sample for reinforcement. The screw 407 is then continuously rotated to drive the soil sampling sleeve 502 to continue to descend. When the adjacent oblique insertion hole 507 is close to the ground, the oblique insertion rod 506 is again inserted into the oblique insertion hole 507 and penetrated into the soil sample. This process is repeated from the outside to the inside through the oblique insertion hole 507 to insert the oblique insertion rod 506 into the soil sample in the soil sampling sleeve 502. In this way, the soil sample in the soil sampling sleeve 502 can be reinforced with the help of the oblique insertion rod 506, and then the soil sample can be prevented from detaching from the soil sampling sleeve 502 during the process of pulling the soil sampling sleeve 502 upward after the soil sampling is completed, thereby avoiding the situation of soil sampling failure. The soil sampling depth of the soil sample should be controlled with reference to the scale value of the scale ruler 504. When the soil sampling sleeve 502 enters the ground to the required soil After the sampling depth is reached, the forward rotation of the stud 407 is stopped, and the stud 407 is reversed counterclockwise again to drive the soil extraction sleeve 502 to rise vertically and be pulled out. In this way, the forward and reverse rotation of the stud 407 of the driving assembly 4 can drive the soil extraction sleeve 502 of the sampling assembly 5 to rise vertically, and then the soil extraction sleeve 502 can be vertically pressed into the foundation sampling position for soil extraction operation, and after the soil extraction is completed, the soil extraction sleeve 502 can be vertically pulled out. The soil extraction operation method is simple and easy to implement. At the same time, since the method of rotating the stud 407 is used instead of the soil extraction operation method of pressing the soil extraction sleeve 502 with force, the physical requirements of the operator are reduced, which is conducive to ensuring the smooth completion of the soil extraction process, and the soil extraction sleeve 502 is in the process of taking out the soil sample.By rotating the stud 407 to drive the soil extraction sleeve 502 to rise vertically along the stud 407, the push plate 4010 can push out the soil sample in the soil extraction sleeve 502. At the same time, by coaxially sliding with the inner wall of the soil extraction sleeve 502, the push plate 4010 can scrape and clean the inner wall of the soil extraction sleeve 502, which ensures that the soil sample in the soil extraction sleeve 502 can be smoothly and completely removed, and avoids residual soil sample adhering to the inner wall of the soil extraction sleeve 502.
[0040] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
