Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a geotechnical engineering testing and sampling device, which solves the problem that the current sampling equipment cannot remove the large rocks in the rock and soil, so that the large rocks block the sampling port, causing the interruption of sampling. The efficiency is low, and the traditional sampling equipment accumulates a large amount of air inside when sampling, and the rock and soil are loose after extraction, which cannot truly reflect the situation in the rock and soil and reduces the quality of sampling.

Embodiment 1

[0033] like Figure 1-3 As shown, the present invention provides a technical solution: a geotechnical engineering detection sampling device, including a sampling intubation 1, the bottom of the sampling intubation 1 is fixedly connected with a displacement cone 2, and the two outer sides of the sampling intubation 1 and near the top The lateral symmetry is fixedly connected with a rotating support rod 3, the outer surface of the sampling intubation tube 1 is uniformly provided with a driving thread 4, and the bottom end of the outside of the displacement cone 2 is fixedly connected with an insertion and extraction circular groove 5, and the bottom of the insertion and extraction circular groove 5 is uniformly arranged There is a stone removal mechanism 6, and the middle position inside the sampling cannula 1 is slidably connected with a tight pressing plate 7, and the surface of the tight pressing plate 7 is evenly provided with sieve holes 8, and the inner surface of the sampl...

Embodiment 2

[0036] like Figure 4-5 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: a geotechnical engineering detection and sampling device, the stone removal mechanism 6 includes a movable inner groove 601, and the movable inner groove 601 is uniformly arranged in the insertion and removal circular groove 5. On the outer surface, the inside of the movable inner tank 601 and the position close to the bottom end are rotatably connected with a shoveling ramp 602 , and the back side of the shoveling ramp 602 is fixedly connected with an inner shoveling slide plate 603 near the bottom. The collected rock and soil can be properly compressed, the air in the rock and soil can be squeezed out, and the compactness of the rock and soil can be appropriately improved.

[0037] An elastic sleeve 604 is fixedly sleeved and slidably connected to the top of the shoveling inclined insertion plate 602 , and a blocking inclined insertion plate 605 is evenly and ...

Embodiment 3

[0042] like Image 6 As shown, on the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: a geotechnical engineering testing and sampling device, the rejecting assembly 606 includes a driving platen 6061, the driving platen 6061 and the inner shoveling slide 603 The inner rotation is connected, and the bottom surface of the driving platen 6061 is evenly rotated and connected with a movable scraper hook 6062 .

[0043] The bottom surface of the driving platen 6061 and the position above the movable scraper hook 6062 are evenly and fixedly connected with a stone push rod 6063, and the middle position of the movable scraper hook 6062 is provided with a restriction slot 6064, and the stone push rod 6063 and the restriction slot 6064 internal corresponding settings. The stones are blocked on the outside, and with the gradual progress of the overturn, the rock ejector rod 6063 is aligned with the position of the stones, so as to reduce the a...

Abstract

The invention relates to a geotechnical engineering detection sampling device. The device comprises a sampling insertion pipe; the bottom of the sampling insertion pipe is fixedly connected with a squeezing taper pipe; the outer side of the sampling insertion pipe and the two sides, close to the top, of the sampling insertion pipe are symmetrically and fixedly connected with rotating handrails; the outer surface of the sampling insertion pipe is uniformly provided with driving threads; an inserting and taking circular groove is fixedly connected to the bottom end of the exterior of the squeezing taper pipe; stone removing mechanisms are evenly arranged at the bottom of the inserting and taking circular groove; a compact pressing plate is slidably connected to the middle position of the interior of the sampling insertion pipe; and screening holes are evenly formed in the surface of the compact pressing plate; resistance-increasing taper plates are uniformly and fixedly connected to the surface of the interior of the sampling insertion pipe; and the inner side surfaces of the resistance-increasing taper plates are in corresponding contact with the outer side surface of the compact pressing plate. The invention relates to the technical field of engineering detection. According to the geotechnical engineering detection sampling device, rock soil on the inner side of the bottom of the device is removed outwards, blockage caused by accumulation of stones below the device is avoided, and the sampling precision is improved.
