Underwater rock and soil foundation exploration and sampling equipment suitable for rock and soil engineering

Abstract

The invention provides underwater rock and soil foundation exploration and sampling equipment suitable for rock and soil engineering, and relates to the field of rock and soil engineering. The underwater rock and soil foundation exploration and sampling equipment suitable for the rock and soil engineering includes a machine frame, a shell, a motor, a drill bit and an adjusting assembly. The shellis arranged in the middle of the machine frame, the motor is arranged in the shell, and a motor transmission shaft is connected with the drill bit. The drill bit extends below the shell and a samplingpipe is arranged on the drill bit. The sampling pipe is spirally coiled on a drill bit rod. The underwater rock and soil foundation exploration and sampling equipment suitable for the rock and soil engineering is suitable is suitable for underwater work and convenient for underwater rock and soil foundation exploration. A detection assembly and the adjustment assembly are matched, and a role of adjusting the angle of the drill bit is played, so that an electric drill drills vertically and downwards into rock and soil. Through the cooperation of a cleaning assembly, a silica gel sleeve and a water pump, sand at the bottom of water can be lifted to expose the rock and soil at the bottom of the water, so that the sampling pipe is directly in contact with the rock and soil, and the efficiencyand speed of underwater rock and soil sample collection are improved.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to an underwater rock and soil foundation exploration sampling device suitable for geotechnical engineering. Background technique [0002] Foundation geotechnical engineering survey refers to the activities of ascertaining, analyzing and evaluating the geological, environmental characteristics and geotechnical engineering conditions of the construction site and compiling survey documents according to the requirements of the construction project. The structure and properties of rock and soil have an important impact on the bearing capacity, so the sampling and analysis of rock and soil is an essential part of the work before construction. The original test soil was extracted by the rock soil sampling device as a sample to understand the nature of the base layer. [0003] For example, the "Soil Sampling Device Suitable for Rock and Soil Testing" is disclosed in the C...
