Deep cement soil slurry sampling device for geological exploration

Abstract

The invention discloses a deep cement soil slurry sampling device for geological exploration. The deep cement soil slurry sampling device comprises a supporting frame, a rotary sinking assembly and asampling assembly, wherein the rotary sinking assembly is slidably connected to the middle part of the supporting frame, and is used for assisting the sampling assembly to sink to the cement soil slurry; the supporting frame is fixed to the tail of a trailer, the rotary sinking assembly is fixed to a tightening device at the tail of the trailer through a lifting rope, and the supporting frame is used for supporting and limiting the rotary sinking assembly; and the sampling assembly is arranged in the rotary sinking assembly and is used for collecting cement soil slurry samples at different depths.

Description

technical field [0001] The invention belongs to the technical field of sampling devices, in particular to a deep cement soil slurry sampling device for geological exploration. Background technique [0002] Geological exploration is to conduct geological exploration and detection through a variety of different methods, and to investigate and study the geological conditions in a certain area. Among them, the frequently used geological exploration method is the sampling method, and complex and diverse sampling devices are also used to adapt Sampling work in different environments, however, according to investigations, the current existing sampling devices for deep cement-soil slurry often have the following problems: [0003] 1. At present, many deep sampling devices only have a single sampling port, that is to say, in the process of one sampling, only a specific depth layer at one location can be sampled, and when sampling at different depths at the same location, repeated ope...

Problems solved by technology

[0003] 1. At present, many deep sampling devices only have a single sampling port, that is to say, in the process of one sampling, only a specific depth layer at one location can be sampled, and when sampling at different depths at the same location, repeated operations are required , greatly reducing work efficiency;

[0004] 2. For the deep cement soil slurry sampling device, because the cement soil slurry contains many solid particles with larger particles, it is easy to block the sampling port during sampling, resulting in sampling failure;

[0005] 3. The bottom sampling device is used. Due to the high pressure in the deep layer, when the sampling port is opened, the pressure is too concentrated and the sample volume cannot be controlled, so that the sampling device is filled with cement-soil slurry, which makes it more troublesome to take out the sample.
