Interval is equipped with multiple groups soil sample grasping mechanism on the round straight-bar between shape slice, and the soil sample grasping mechanism includes semicircle
Ring body and the portion that is fixedly connected for connecting the semi-circular ring, the semi-circular ring are rotatably installed on the round straight-bar
On, the portion that is fixedly connected is connect with switching action portion.
The semi-circular ring is formed with straight-bar interconnecting piece, shape on the straight-bar interconnecting piece with the position being fixedly connected between portion
At there is connecting hole.
Portion and the switching action portion of being fixedly connected is welded to connect.
The switching action portion is the arc panel of semi-circular shape, and two switching action portions can form a circle after closing up
Body.
Magnet for fixed sampling sample skin is installed on the inner wall of the semi-circular ring.
The present invention reduces the perturbations of soil sample, make taken undisturbed soil sample closer to the objective shape under natural conditions
State, so that the indices in soil test, especially mechanical index are more accurate, to provide reliable geology ginseng for design
Number foundation.

Specific embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that described herein
Specific embodiment be only used to explain the present invention, be not intended to limit the present invention.
Referring to shown in Fig. 1-7, a kind of ground sample sampler for geotechnical engineering investigation, including：
One round straight-bar 4, connecting two spacing distances by fixed link 7 respectively on the bar wall of the circle straight-bar is to want
The circular slice 1 of the length of the ground core taken, the diameter of the circular slice is consistent with the diameter for the ground core to be taken, the circle
Shape slice is located at the same side of the round straight-bar；Interval is equipped with multiple groups on the round straight-bar between the circular slice
Soil sample grasping mechanism, the soil sample grasping mechanism include that semi-circular ring 6 and the connection semi-circular ring are fixedly connected with portion 9,
The semi-circular ring is rotatably installed on the round straight-bar, and the portion 9 that is fixedly connected is connect with switching action portion 5.
Wherein, the position between the semi-circular ring 6 and the portion that is fixedly connected 9 is formed with straight-bar interconnecting piece 2, and the straight-bar connects
Connecting hole 8 is formed in socket part, the circle straight-bar 4, which passes through the connecting hole 8 and the formation of multiple groups soil sample grasping mechanism, to be turned
Dynamic formula connection, multiple groups soil sample grasping mechanism be staggered certain distance setting.
It should be noted that it can be set with torsional spring (not shown) on the round straight-bar 4 in the present invention, torsional spring
Both ends can the semicircular ring opposite with two respectively inside face contact, so as to grab the soil sample using the torsional spring
The semi-circular ring 6 of mechanism keeps open configuration in a free state, it is of course also possible to not fill, it is not necessary to keep in a free state
The state of opening, it is specific unlimited.
Wherein, portion and the switching action portion of being fixedly connected is welded to connect, wherein described is fixedly connected with portion and folding behaviour
Make to be formed with one section of curved portion on the face of portion's connection, as shown in fig. 6, to be cooperatively connected with switching action portion face contact.Institute
It states fixed link 7 and round straight-bar is welded to connect.
Wherein, the switching action portion is the arc panel of semi-circular shape, and two switching action portions can be formed after closing up
One round.The length in the switching action portion is less than the length of the round straight-bar, thus in the round straight-bar
Two close end side formed sampling when press operating part, with facilitate sampling be in one's hands column circle straight-bar carry out pushing operation, with sampling.
Further, in the present invention, on the inner wall of the semi-circular ring 6, magnet (not shown), glue can also be installed
Eliminant is fixed in the groove 3 at multiple intervals prefabricated on the inner wall of semi-circular ring, not high after being mounted in the groove 3
In the inner wall of semi-circular ring, former curved surfaces are kept, is mainly used for the fixed thin sampling sample skin (not shown) of absorption type, i.e., will
Sampling sample skin is fixed on the inner wall of semi-circular ring, can also be fixed using other way, such as sizing material or welding, specifically not
Limit, the sampling sample skin are rectangular-shaped soft irony skin, wherein the sampling sample skin is two, is separately fixed at two
Side, length is consistent with the length for the ground core to be taken, and width is consistent or slightly smaller with the diameter of semi-circular ring 6, is fixed on semicircle
On the inner wall of ring body 6, so that the inside that is spaced between the semi-circular ring of the same side at multiple intervals be closed, conveniently take
Sample, the fracture of ground core when preventing from sampling.
Device application method is as follows：
Device for opening puts sampling sample skin in the device of opening into, and magnet is sucked by sample skin is sampled, and will sample sample pico-ampere
Mounted in the inside of the soil sample grasping mechanism.Apparatus of the present invention, which are placed on ground core, needs sampling point, at this time with the hands to
Then the round straight-bar of lower pressing holds two sections of switching action portions at top, makes it simultaneously so that two circular slices cut off soil sample
Hold together, under lever principle effect, lower part soil sample grasping mechanism also closes up, and just catches the soil sample cut, can thus incite somebody to action
The soil sample cut proposes soil sample groove.
The present invention has the following advantages that：
1. improving the operating efficiency of sampling
2. reducing the perturbation of soil sample, makes taken undisturbed soil sample closer to the objective status under natural conditions, make
Indices in soil test, especially mechanical index is more accurate, thus for design provide reliable geologic parameter according to
According to.
3. the both hands for sampling worker are freed from muddy water, construction environment is improved.
The above is only a preferred embodiment of the present invention, it is noted that for the common skill of the art
For art personnel, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
