Sampling device based on water conservancy project investigation

Abstract

The invention provides a sampling device for water conservancy project survey, relates to the technical field of water conservancy survey, and solves the problems that the length of a drill rod of a sampling device cannot be adjusted, and inconvenience is brought to field operation of workers due to the fact that the length of the drill rod is not enough when deep soil is sampled. The sampling device for water conservancy project investigation comprises a device box, an indication groove in the vertical direction is formed in the middle of the outer end face of the device box, and a threaded hole is formed in the middle of a bottom plate of the device box; a fixing plate is installed in the device box, and a threaded hole is formed in the middle of the fixing plate. According to the device, the hexagonal clamping grooves are formed in the lower ends of the second drill rods, the second clamping columns are installed at the upper ends of the second drill rods, and when a worker conducts exploration and sampling on a deep soil layer, the total length of the drill rods can be increased by stacking the second drill rods, so that the device can conduct sampling operation on soil at different depths.

Description

technical field [0001] The invention belongs to the technical field of water conservancy survey, in particular to a sampling device based on water conservancy engineering survey. Background technique [0002] Water conservancy survey is one of the basic work of water conservancy construction, which is closely related to the investment and safe operation of the project. Before the construction of the project, sampling the soil in the construction area can determine the geological conditions of the construction area and avoid accidents during the later construction. , but the existing sampling device has some deficiencies in use. [0003] Based on the above, the existing sampling device has the following problems in use: First, the terrain in the field is uneven, the length of the support rod at the lower end of the device box is fixed, and there is a problem when workers fix the device on the slope. It is difficult, and it is impossible to ensure that the sampling mechanism ...

Problems solved by technology

[0004] The purpose of the present invention is to address the above problems. The present invention provides a sampling device based on water conservancy engineering investigation, which solves the problem that the length of the support rod at the lower end of the sampling device is fixed, and that workers have difficulties in fixing the device on the slope, and The length of the drill pipe cannot be adjusted. When sampling the deep soil, the length of the drill pipe is not enough, which brings inconvenience to the workers in the on-site operation; in addition, when the workers store and transport the sampling bottles, it is easy to Broken sample bottle problem
