Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sampling devices, in particular to a backfill soil sampling device. Background Art
[0002] As we all know, with the rapid economic growth, there are more and more large-span structures, high-rise and super-high-rise buildings. Improving design standards and increasing structural loads have put higher and higher requirements on foundation stability. The construction quality and construction technology of backfill soil have also received more and more attention. Project supervisors will regularly test the soil quality.
[0003] According to a Chinese patent, a backfill soil sampling device is disclosed with the publication number CN202123124730.7. When sampling, the device first stands up the cylinder, rotates the support rod on the cylinder to abut against the ground, inserts the pin connected to the support rod into the ground, and then fixes the position of the support rod through a fixing assembly to make the entire device more stable during use. After the entire device is fixed, the driving rod drives the sampling cylinder and the ring knife downward under the drive of the driving assembly, and inserts them into the ground to complete the sampling. During the sampling process, the device is directly fixed with pins to provide stable support for the sampling cylinder. However, due to the uneven backfill ground, the sampling accuracy of the device is not high, which affects the sampling effect.
[0004] Therefore, we designed a backfill soil sampling device to optimize the above scheme. Utility Model Content
