Description

Soil sampling device for rock and soil exploration

Technical Field

Background

Before the design and development of the building engineering, geotechnical engineering investigation needs to be carried out on construction land so as to find out the engineering geological conditions, analyze existing geological problems, carry out engineering geological evaluation on a construction area and further guide the engineering design and construction. The geotechnical investigation process utilizes soil sampling device usually, takes a sample to construction land soil, then presents the geological evaluation report through inspection experiment etc.. Therefore, the biggest factor affecting the accuracy and authenticity of the experiment is the quality of the obtained soil sample.

In the patent of chinese patent No. CN211292062U, a building rock investigation sampling device is described, the device is through setting up mobilizable processing case to be fixed in the processing incasement portion with soil sampling device, make the device can more convenient removal, when satisfying basic soil sampling demand, be convenient for sample constructor mobile device more. But the problem that the device exists is, mobilizable gyro wheel can not the height-adjusting angle, can only remove on relatively level road surface basically, and to most of construction soil, when carrying out the ground reconnaissance, often can meet the unevenness in ground's condition, the device not only can't convenient removal this moment, because sampling device is fixed with the processing case, when the processing case slope, sampling device also can incline, and then leads to the sample inaccurate, even unable sample.

In chinese patent No. CN211598537U, a drilling apparatus for geotechnical investigation in building foundation construction is described, which can support a cavity during drilling by installing a supporting apparatus on a base, thereby improving the stability of drilling. However, the device has the problems that the soil sample obtained by using the helical blade damages the soil texture of the soil in the direction vertical to the ground, and the water content, chemical components and the like of the soil are further damaged in the process of taking the soil out and transferring the soil to another container, so that the accuracy and the authenticity of the inspection are influenced.

However, this device has a problem in that when the geology of the ground is soft, the fixing of the device cannot be well accomplished due to the small number of the fixing bases, and the soil drilled out using the helical blade may be difficult to obtain due to the fluidity of the soil.

3. The sampling requirements of different soil properties cannot be met at the same time. For example, a drilling mode can be adopted for harder geology, but the drilling mode is also adopted for softer geology, so that the soil structure is extremely easy to damage, even a soil sample is difficult to take out due to the fluidity of the soil, and the pressure exploration mode is more suitable for the softer geology.
