Embodiment

[0024] Such as figure 1 , figure 2 , image 3 and Figure 4 Shown: a rock and soil layered sampling device, including a rectangular hollow sampling cylinder 1, the bottom of the sampling cylinder 1 is provided with a hollow drill bit 5, the drill bit 5 is in the shape of a square pyramid, and the drill bit 5 is sleeved on the bottom of the sampling cylinder 1 , and fixed by bolt connection; handles 3 are fixed on the two side walls of the sampling cylinder 1, and the top of the sampling cylinder 1 is clamped with a sealing cover 2; the inner wall of the sampling cylinder 1 is provided with two oppositely arranged chutes 4, the chute 4 is slidingly connected with a rectangular limit ring 6, and the two side walls of the limit ring 6 are welded with a connecting block 7 extending into the chute 4 to slide, and the connecting block 7 is provided with a drive motor 16 that drives the connecting block 7 to slide. The side wall of the slot 4 is provided with a vertical tooth gro...

specific Embodiment approach

[0025] Holding the handle 3, the sampling device is vertically inserted into the rock and soil until the positioning ring 20 at the bottom of the sampling cylinder 1 is at the bottom of the desired sample; the drive motor 16 is started by the PLC controller, and the drive motor 16 drives the gear 17 to rotate. The engagement between the gear 17 and the tooth groove drives the connecting block 7 to slide downward, thereby driving the limiting ring 6 to slide downward until the limiting ring 6 slides to the top of the desired sample, and the driving motor 16 is turned off.

[0026] Simultaneously start the fourth telescopic cylinder 14 through the PLC controller, and the fourth telescopic cylinder 14 drives the cut-off plate 15 to slide towards each other until the fourth telescopic cylinder 14 moves to the limit position, and the fourth telescopic cylinder 14 is closed. The upper layer of rock and soil is cut off from the lower layer of rock and soil; and then the third telescop...

Abstract

The invention relates to the field of rock-soil sampling, and particularly discloses a rock-soil stratified sampling device which comprises a rectangular hollow sampling barrel, and a hollow drill bitis arranged at the bottom of the sampling barrel; two oppositely-arranged sliding grooves are formed in the inner wall of the sampling barrel, rectangular limiting rings are connected into the sliding grooves in a sliding mode, connecting blocks extending into the sliding grooves to slide are fixed to the two side walls of each limiting ring, and driving motors for driving the connecting blocks to slide are arranged on the connecting blocks; a cavity is formed in each connecting block, a first telescopic air cylinder penetrating through a limiting ring is fixed in the cavity, a vertically-arranged first electric heating plate is fixed to the extending end of the first telescopic air cylinder, and a cavity for containing the first electric heating plate is formed in the inner wall of the limiting ring; a plastic shading bag is arranged between the bottom of each limiting ring and the bottom of the sampling cylinder; the diameter of the shading bag is smaller than the length of the electric heating plate; the invention aims to solve the problem that an existing sampling device cannot perform stratified sampling in the sampling process.

Description

technical field [0001] The invention relates to the technical field of rock and soil sampling, and specifically discloses a layered rock and soil sampling device. Background technique [0002] Geotechnical engineering is to solve rock mass and soil engineering problems, including foundation and foundation, slope and underground engineering, etc., as its own research object. Soil sampling should pay great attention to the quality of soil samples; and in the research process, it is often necessary to sample the rock and soil at the bottom, but the structure of the rock and soil is very easy to be stirred during the drilling and soil taking process of the existing sampling device, resulting in Different levels of rock and soil disturbance are mixed, and the soil samples whose structure has been disturbed will be used for testing, and wrong conclusions will inevitably be obtained, which will cause engineering accidents or waste construction funds.
