Abstract
The utility model discloses a kind of visual undisturbed unsaturated expansive soils hollow cylinder specimen sampling instrument, by spinner (1), support (2), steel membrane (3), cut earthenware (4), camera (5), computer (6) form, wherein cut earthenware (4) and be made up of auger drill head (7), casing (8), drilling rod (9); The beneficial effects of the utility model are: the drill bit adopting a series of diameter respectively, the disposable undisturbed unsaturated expansive soils sample effectively preparing different size, drill bit is combined with casing device and camera, effectively can cut core, prevent soil bits from sticking with hole wall, and it is little on the raw disturbance of local products, soil compaction impact to get core process, spinner drives the rotation of rotating disk, be convenient to cutting of swelled ground outer wall, light and handy, convenient, practical.
Description
Technical field
The utility model relates to a kind of visual swelled ground hollow cylinder specimen sampling instrument of integration being applicable to soil sample cutting and extracting.
Background technology
The area distributions of China's swelled ground is extensive, and to hard plastic state, intensity is high in hard under native state for swelled ground, has the character of imbibition and dehydration shrinkage simultaneously.The harm caused to engineering just because of the special nature of swelled ground increases gradually.Therefore, the experimental study for undisturbed unsaturated expansive soils is increasingly important.But undisturbed unsaturated expansive soils is because of its hollow sample preparation difficulty, the huge expensive Elements research that waits of existing instrument is less, hinders the experimental and theoretical study of such soil body to a great extent.How to produce undisturbed unsaturated expansive soils hollow cylinder sample and become a problem instantly.
Summary of the invention
The technical problems to be solved in the utility model is, on the basis of original soft clay hollow sampling instrument, the drill bit of a series of diameter is set, development undisturbed unsaturated expansive soils hollow cylinder sample sample making apparatus, set up spinner simultaneously, drive dial rotation with spinner, thus be convenient to the outer wall that fret-saw cuts swelled ground.
Technical characteristics of the present utility model is: by spinner, support, cut earthenware, steel membrane, camera, computer form.Wherein, cut earthenware and be made up of the auger drill head of the knife edge, a series of diameter, drilling rod and casing, the knife edge is divided into again the horizontal knife edge, the edge knife edge and the inner edge knife edge.
The beneficial effects of the utility model are: the auger drill head adopting a series of diameter respectively, the disposable undisturbed unsaturated expansive soils sample effectively preparing different size; Drill bit is combined with casing device and camera, effectively can cut core, prevents soil bits from sticking with hole wall, and it is little on the raw disturbance of local products, soil compaction impact to get core process; Spinner drives the rotation of rotating disk, is convenient to cutting of swelled ground outer wall, light and handy, convenient, practical.
Accompanying drawing explanation
Wherein, Fig. 1 is undisturbed unsaturated expansive soils hollow cylinder specimen sampling instrument unitary construction figure, and Fig. 2 is for cutting earthenware front elevation.Icon in Figure of description is:
1---spinner; 2---support; 3---steel membrane; 4---cut earthenware; 5---camera; 6---computer; 7---auger drill head; 8---casing; 9---drilling rod
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
A kind of visual undisturbed unsaturated expansive soils hollow cylinder specimen sampling instrument, by spinner 1, support 2, steel membrane 3, cut earthenware 4, camera 5, computer 6 form, wherein cut earthenware 4 to be made up of auger drill head 7, casing 8, drilling rod 9, and support 2, steel membrane 3, casing 8, drilling rod 9 are stainless steel.Drill bit a diameter is 20mm, b diameter be 40mm, c diameter be 60mm, d diameter is 80mm, is highly 200mm; Casing a diameter is 60mm, be highly 200mm, b diameter is 160mm, is highly 400mm; Steel membrane a diameter is 100mm, be highly 200mm, b diameter is 200mm, is highly 400mm.Circle disk center position all has a diameter to be the circle print of 25mm, is for mark places the position of undisturbed unsaturated expansive soils, to ensure the axle center of drill bit and undisturbed unsaturated expansive soils sample point-blank.
Because under swelled ground native state, to hard plastic state, intensity is high in hard, when outer wall cuts, hand rotation is unfavorable for operation, arranges spinner here, forms primarily of electro-motor, the rotation of drive disk thus be convenient to the cutting of swelled ground outer wall.
Sample outer wall cuts
Be fixed on rotating disk by swelled ground soil block, in figure, large and small steel column locations is determined by fixed large and small sample external diameter, and cut along sample preparation platform both sides steel column with fret-saw, the sample external diameter cut so just in time meets the demands.In sample making course, spinner drives dial rotation, is convenient to soil sample and cuts.After sample outer wall preliminarily forming, then use scraper smoothing, namely complete outer wall and cut.
Core got by sample
Before getting core, drilling rod is inserted in casing; Loosen knife edge set screw, the mobile and horizontal knife edge, make the outer rim knife edge be sample inside radius length to bit central point distance; Camera to be fixed on support and to be connected with computer.
Cutting of inner core: by cutting device auger drill head and sample bottom centre point cantact, slow promotion drilling rod, make it to make spiral promotion, the inside and outside edge knife edge then requires soil bits to be separated with sample inwall according to aperture, cutting soil bits are divided into strip to the knife edge is then synchronous by level, make it to come off under gravity.Because swelled ground has soil to consider to be worth doing and the not segregative situation of inwall, drill bit is combined effectively can cuts core with casing device, prevents soil bits from adhering to hole wall, and affects less on the disturbance of the soil body and soil compaction in cutting process.
Claims (3)
1. a visual undisturbed unsaturated expansive soils hollow cylinder specimen sampling instrument, it is characterized in that: by spinner (1), support (2), steel membrane (3), cut earthenware (4), camera (5), computer (6) form, wherein cut earthenware (4) and be made up of auger drill head (7), casing (8), drilling rod (9).
