Description

Technical Field

[0001] The utility model belongs to the technical field of soil sampling, and specifically relates to a sampling device for engineering geological survey. Background Art

[0002] Geological exploration is a survey and research activity that uses various means and methods to survey and detect geology, determine the appropriate bearing layer, determine the foundation type according to the bearing capacity of the bearing layer, and calculate the foundation parameters. It is an investigation and research activity on the geological conditions such as rocks, strata, structures, minerals, hydrology, and landforms in a certain area to investigate and study the geological conditions of rocks, strata, structures, minerals, hydrology, and landforms in order to find out the quality and quantity of minerals and the technical conditions for mining and utilization, and provide the mineral reserves and geological data needed for mine construction design.

[0003] In the process of geological exploration, sampling of soil layers is a very important step. Most sampling devices in the prior art are fixedly installed in one position and cannot be moved. This makes the use of the sampling devices more troublesome and it is impossible to effectively adjust the position of the sampling devices.

[0004] The existing patent (application number: CN202122144999.5) proposes a soil sampling device for engineering geological survey, including a mobile seat, the four corners of the bottom of the mobile seat are provided with supporting legs, a rotating rod is horizontally arranged inside the mobile seat, and both ends of the rotating rod extend out of the mobile seat; support rods are arranged at both ends of the rotating rod, and the support rods are sleeved on the outside of the rotating rod; a first motor is arranged at the bottom of the mobile seat; the position of the device can be effectively prevented from being offset during soil collection. At the same time, the device has a simple structure, is easy to use and store, and has a low production cost.

[0005] Drilling into the geology to take samples will cause soil to splash during the process. After sampling, the samples are usually scattered outside, which makes it inconvenient for staff to collect the samples and reduces the sampling efficiency of staff.

[0006] In view of this, this application is hereby filed. Utility Model Content
