[0001] The utility model belongs to the technical field of road and bridge subgrade inspection and sampling, and particularly relates to a road and bridge subgrade inspection and sampling device. Background Technique

[0002] In the field of road and bridge engineering, the quality of the subgrade directly affects the bearing capacity and service life of roads or bridges. Therefore, regular inspection and evaluation of the subgrade are important links to ensure the safe operation of roads or bridges. A key step in subgrade inspection is to collect subgrade samples for detailed laboratory analysis.

[0003] Traditional subgrade sampling methods mostly use manual or simple mechanical drilling methods, which have problems such as low operation efficiency, insufficient accuracy, and possible damage to the subgrade. In recent years, with the continuous development of construction machinery technology, various new types of subgrade inspection and sampling devices have been developed. These devices usually combine advanced mechanical technology and electronic technology to improve the efficiency, accuracy, and operation convenience of subgrade sample collection. However, although there are already various subgrade inspection and sampling devices on the market, there are still some deficiencies, such as insufficient sampling accuracy, inconvenient operation, and room for improvement in equipment stability.

[0004] Therefore, we provide a road and bridge subgrade inspection and sampling device to solve the above problems. Content of the Utility Model

The sampler 1 includes a support 11, a motor 12 fixed on the upper side of the support 11, a power handle 13 threadedly and adaptively installed on the side of the edge of the support 11, a drill rod 14 connected to the output shaft of the motor 12, a kit 16 arranged at the lower part of the drill rod 14, and a helical blade 17 fixed on the periphery of the lower end of the drill rod 14; the sampling tray 2 includes an end cover 21 fixed on the lower side of the kit 16, a shielding ring 22 threadedly and adaptively installed under the end cover 21, a collection tray 23 fixed on the lower part of the shielding ring 22, a sleeve 24 arranged at the lower part of the collection tray 23, and a positioning disk 25 movably arranged at the bottom of the sleeve 24.

[0025] Regarding the further description of the above structure:

[0026] The support 11 is an L-shaped structure, and shock-absorbing sheets are equidistantly spaced on the side of the support 11; the power handle 13 is internally provided with a rechargeable power module, and the power module is connected to the motor 12. A control button is arranged on the side of the power handle 13, and the control button is also connected to the power module; a spring 15 is sleeved outside the drill rod 14, and the spring 15 is located between the lower part of the support 11 and the upper side of the end cover 21.

[0027] The lower side of the positioning disc 25 is serrated. The spiral blade 17 passes through the sleeve 24 and enters the roadbed interior with the positioning disc 25. The spiral blade 17 is located inside the sleeve 24, and the upper part of the spiral blade 17 is higher than the inner edge of the collection disc 23. An annular collection groove is provided inside the collection disc 23.

[0028] This device for detecting and sampling roadbed of a road and bridge aims to improve the efficiency, accuracy and operation convenience of roadbed sample collection, ensuring the high efficiency and accuracy of roadbed sample collection. The following is a detailed description of the device and its usage method:

[0029] The support 11 adopts an L-shaped structure to provide a stable installation foundation. The shock-absorbing sheets equidistantly installed on its side can effectively absorb the vibration during drilling, ensuring a smooth sampling process and reducing physical damage to the sample.

[0030] The power handle 13 with a built-in rechargeable power module not only provides a portable power source but also directly controls the motor 12 through the control buttons on the side. The operation is simple and fast. The motor 12 is connected to the drill pipe 14 through the output shaft to provide power for drilling.

[0031] A spring 15 is sleeved outside the drill pipe 14, which can buffer the impact during drilling to protect the equipment. The spiral blade 17 is installed at the lower end of the drill pipe 14 to effectively cut and carry the roadbed soil. The spring 15 is located between the lower part of the support 11 and the end cover 21, further enhancing the seismic performance of the equipment.

[0032] The sampling disc 2 includes an end cover 21 fixed to the lower part of the kit 16, and a shielding ring 22 and a collection disc 23 connected thereto. An annular collection groove is provided inside the collection disc 23 for collecting roadbed samples. The movable positioning disc 25 is located at the bottom of the sleeve 24, and its serrated lower surface helps to fix the sample position and prevent the sample from scattering during extraction.

[0033] The usage method of this device for detecting and sampling roadbed of a road and bridge is as follows:

[0034] Ensure that the rechargeable power module of the power handle 13 is fully charged, then firmly screw the handle onto the support 11, and check whether all connecting parts are tightened to ensure the stability of the device;

[0035] Correctly connect the end cover 21 of the sampling disc 2 to the kit 16 at the lower end of the drill pipe 14, and install the shielding ring 22 and the collection disc 23 through thread adaptation. Finally, install the positioning disc 25 to ensure the stable installation of all components.

[0036] Press the control button on the power handle 13 to start the motor 12. At this time, the spiral blade 17 starts to rotate. The operator needs to steadily press down the sampler 1 to gradually penetrate the spiral blade 17 into the roadbed. During the rotary drilling process, the spiral blade 17 gradually pushes the drilled roadbed material upward.

[0037] As the drilling progresses, the cut subgrade soil is guided by the spiral blade 17, passes through the sleeve 24, and finally is fed into the annular collection groove of the collection tray 23;

[0038] After reaching the predetermined sampling depth, stop the motor 12, slowly lift the sampler 1, and then, disassemble the sampling tray 2, number the samples in the collection tray 23, record the depth information, and send them to the laboratory for analysis;

[0039] After each use, the residual soil on components such as the spiral blade 17 and the collection tray 23 should be cleaned in time to keep the equipment in good condition for the next use.

[0040] Through the above steps, the device can efficiently and accurately complete the collection of subgrade samples, providing reliable data support for subsequent subgrade analysis and evaluation.
