Embodiment 1

[0052] Referring to the accompanying drawings, a convenient sampling device for geotechnical testing in civil engineering includes a vertical frame 101, the bottom end of the vertical frame 101 is equipped with a moving wheel 102, a driving box 103 is arranged between the vertical frames 101, and the top of the driving box 103 is connected There is a longitudinal guide rod 104, the longitudinal guide rod 104 penetrates the top of the stand 101, and the top is also provided with an anti-separation plate 105;

[0053] The drive box 103 is provided with a drive assembly 2, a switch assembly 3 is disposed on one side of the drive assembly 2, and a drill bit assembly 4 is disposed on the other side; the drill bit assembly 4 is provided with a plurality of sets of sampling assemblies 6 for collecting geotechnical soils of different soil layers The sampling assembly 6 is matched with the driven assembly 5; the drill bit assembly 4 is also equipped with a lifting assembly 7 on one side...

Embodiment 2

[0055] see attached figure 1 , an easy-to-operate sampling device for geotechnical testing in civil engineering, comprising a stand 101, the bottom end of the stand 101 is equipped with a moving wheel 102, a drive box 103 is arranged between the stands 101, and the top of the drive box 103 is connected with a longitudinal guide The rod 104, the longitudinal guide rod 104 penetrates through the top of the stand 101, and the top is also provided with an anti-separation plate 105;

[0056] The drive box 103 is provided with a drive assembly 2, a switch assembly 3 is disposed on one side of the drive assembly 2, and a drill bit assembly 4 is disposed on the other side; the drill bit assembly 4 is provided with a plurality of sets of sampling assemblies 6 for collecting geotechnical soils of different soil layers The sampling assembly 6 is matched with the driven assembly 5; the drill bit assembly 4 is also equipped with a lifting assembly 7 on one side; the switching assembly 3 is...

Embodiment 3

[0082] On the basis of Example 2,

[0083] see attached Image 6 , the lift assembly 7 also includes a No. 2 driven shaft 704 and a gear set 703;

[0084] The No. 2 driven shaft 704 is located on the side of the No. 1 driven shaft 702, and also penetrates and rotates to connect the top of the drive box 103; The upper section of the No. 2 driven shaft 704 is also provided with threads, which penetrate and screw the top of the stand 101;

[0085] Specifically, when the No. 1 driven shaft 702 rotates, the No. 2 driven shaft 704 is also synchronously reversed through the action of the gear set 703. Since the threads of the two shafts are in opposite directions, the lifting and lowering can still be achieved synchronously; , the lift drive is more reliable.

Abstract

The invention relates to the technical field of rock-soil sampling, in particular to a sampling device and method convenient to operate and used for civil engineering rock-soil detection. A driving box is provided with a driving assembly, one side of the driving assembly is provided with a switching assembly, and the other side of the driving assembly is provided with a drill bit assembly; a plurality of groups of sampling assemblies are arranged in the drill bit assembly and are used for collecting rock soil of different soil layers; the sampling assembly is matched with a driven assembly; a lifting assembly is matched with one side of the drill bit assembly. The switching assembly is used for switching cooperation of the driving assembly and the drill bit assembly or the driven assembly. When the drill bit assembly is driven by the driving assembly to rotate, the lifting assembly synchronously drives the drill bit assembly to ascend and descend, and rapid drilling into rock soil is completed; and then the driven assembly is driven by the driving assembly, so that the sampling assembly can complete rock-soil collection, that is, rock-soil at different depths can be synchronously sampled, and mutual confusion is avoided.

Description

technical field [0001] The invention relates to the technical field of geotechnical sampling, and relates to a convenient sampling device and method for geotechnical detection in civil engineering. Background technique [0002] Civil engineering is a general term for the science and technology of building various engineering facilities. In the actual engineering construction process, it is necessary to sample and analyze the composition of the local geotechnical soil, so as to determine the foundation bearing capacity of different types of soil, and estimate the clay and sand. The shear strength of the soil and the compression deformation index of the cohesive soil are used to judge the consistency state of the cohesive soil, the compactness of the sand and the possibility of vibration liquefaction, so that the stability of the building above the rock and soil is better. [0003] Geotechnical A general term for any kind of rock and soil that makes up the earth's crust from a...
