Problems solved by technology

During the drilling process, the probe will be difficult to lift because of the strong adsorption force of some silt or soft clay, and it cannot be smoothly lowered and lifted in saturated soft clay, often causing the probe to fall in the borehole, causing unnecessary economical loss
The instability of the base cannot ensure that the probe is...

Abstract

The invention relates to a dual-purpose engineering drilling test device, which belongs to the field of engineering drilling equipment. It mainly includes a probe, the bottom of the probe is provided with a connecting plate, and the upper part is provided with a hollow cylinder A, and a base A or a base B is installed under the connecting plate; the hollow cylinder A is equipped with a hollow cylinder B outside, and the hollow cylinder B and the hollow conical cover that is located at the top of its upper part as a slot to form a top cover; the hollow conical cover is composed of a tank shell and a hollow cone, and the tank shell is connected with the hollow cone through a groove, and the groove The hole is assembled from the top of the tank shell and the top of the hollow cone; the hollow cylinder B is provided with a groove with the same width as the tank shell. The beneficial effects of the present invention are: the top cover can overcome the adsorption force of silt and soft clay to the probe, and prevent the probe from falling into the drill hole; the dual-purpose and quick-change base of the ground and underground can realize smooth wall-attachment and fast switching of the probe during testing. In close contact with the ground for a stable test signal.

Description

technical field [0001] The invention relates to a dual-purpose engineering drilling test device, which belongs to the field of engineering drilling equipment. Background technique [0002] In geotechnical engineering surveys, the site is evaluated through geopulsation tests, shear wave velocity tests, etc. in engineering boreholes. In the past drilling equipment, the probe mainly has two fixing methods: plasticine fixed probe and permanent magnetic sucker fixed probe. Plasticine is greatly affected by temperature, and magnet has too high requirements for materials. During the drilling process, the probe will be difficult to lift because of the strong adsorption force of some silt or soft clay, and it cannot be smoothly lowered and lifted in saturated soft clay, often causing the probe to fall in the borehole, causing unnecessary economical loss. The instability of the base cannot ensure that the probe is firmly attached to the position of the measuring point, making the co...
