Abstract
The utility model relates to a multi-section rotary thin wall type soil sampler, which is formed in the following way: a three-way water draining pipe is arranged in a drill rod connector; a ball valve is arranged at the joint of the three-way water draining pipe; the drill rod connector is connected with an outer thread of an annular sleeve pipe through an inner thread of a tail pipe; a soil sample box is mounted in the sleeve pipe; and the outer thread of the sleeve pipe is connected with an inner thread of a spiral bit. The shortages of small one-time soil sampling depth, high water content, difficulty for soil sampling and higher undisturbed soil disturbance in the conventional soil sampler are overcome; as the drill-in type soil sampler is adopted, the soil sampler more easily penetrates into a soil body and is suitable for soil layers with different geological conditions; the soil sampler is high in soil sampling efficiency, can be arbitrarily lengthened according to the need of the soil layer thickness to meet the one-time soil sampling depth, and has a better sampling effect for the soil body with higher water content; and meanwhile, a built-in multi-section soil sample box is adopted, so that great convenience is provided for sample package after sampling and the undisturbed soil disturbance is lower. The soil sampler is simple in structure, low in cost and convenient for sampling.
Description
Technical field:
The utility model relates to a kind of device that gathers soil sample, and the layer thickness that is particularly suited for fetching earth is larger, the larger soil sample barrel of the body water content that fetches earth.
Background technology:
At present, most widely used soil sample barrel is divided into forced and Clothoid type.Forced structure is to be made of parts such as joint, ball valve, remaining pipe, the pipe that narrows, sample bucket and shoes.When fetching earth, the method for generally using at present is plunging, reaches when fetching earth the degree of depth when creeping into, and takes out drilling tool, den bohrkopf abbauen is installed soil sample barrel, then puts into boring, (pass through hammering as mark) in a certain way soil sample barrel is pressed into the soil body, namely propose after filling, unload soil sample barrel taking-up soil sample and get final product.This mode is simple, but certain defect is arranged, and this soil sample barrel is to the geologic condition bad adaptability, and sampling is difficult when running into than the pan soil body; The single degree of depth that fetches earth is less, when the layer thickness that fetches earth is larger, need repeatedly fetch earth; Forced owing to adopting simultaneously, lower ending opening, when running into the very large soil layer of water cut (as turfy soil), soil sample easily drops in leaching process, waits engineering activity to bring inconvenience therefore for construction.And some Clothoid type soil sample barrel, whole device is tube structure, carries boring rear sampling difficulty, needs water filling and washing fluid that soil sample is gone out from top, and is larger to the undisturbed disturbance, can not accurately reflect pattern structure, can not truly reflect the various parameters of soil sample.
Summary of the invention
The purpose of this utility model just is for above-mentioned the deficiencies in the prior art, and a kind of rotation thin-wall sampler is provided.
The purpose of this utility model is achieved through the following technical solutions:
Multistage Rotational Thin wall type soil sample barrel, by being provided with three-way bar water pipe 8 in drill pipe sub 1, be provided with ball valve 2 in the junction of three-way bar water pipe 8, drill pipe sub 1 is connected with the external thread of ring-shaped sleeve 4 by the internal thread of tail pipe 3, soil sample box 6 is housed in sleeve pipe 4, and the internal thread of the external thread of sleeve pipe 4 and auger drill head 7 connects and composes.
Auger drill head 7 is provided with interior shoulder, and interior shoulder is supported soil sample box 6, to soil sample box 6 axial limitings.
Every joint soil sample box 6 is isometric with every joint sleeve pipe 4, and every joint soil sample box 6 contacts cooperation with every joint soil sample box 6.
Beneficial effect: solved the existing soil sample barrel single degree of depth that fetches earth little, water cut large soil body sampling difficulty and the deficiency larger to the undisturbed soil disturbance.Because employing pierces formula, more easily go deep into the soil body, be fit to the stratum of different geological conditions; Soil extracting efficiency is high, and soil sample barrel can increase arbitrarily length according to the needs of the layer thickness that fetches earth, and satisfies the single depth requirements that fetches earth, and is better to the soil body sampling effect that water percentage is larger; Adopt simultaneously the soil sample box of built-in multistage, greatly facilitated the ladle sample after the sampling, less to the undisturbed soil disturbance.This apparatus structure is simple, and is with low cost, and sampling is convenient.
Description of drawings:
Accompanying drawing is multistage Rotational Thin wall type sampler structure figure.
1 drill pipe sub, 2 ball valves, 3 tail pipes, 4 sleeve pipes, 5 connecting pipes, 6 soil sample boxes, 7 auger drill head, 8 three-way bar water pipes.
Embodiment:
The utility model is described in further detail below in conjunction with drawings and Examples:
Multistage Rotational Thin wall type soil sample barrel, by being provided with three-way bar water pipe 8 in drill pipe sub 1, be provided with ball valve 2 in the junction of three-way bar water pipe 8, drill pipe sub 1 is connected with the external thread of sleeve pipe 4 by the internal thread of tail pipe 3, soil sample box 6 is housed in sleeve pipe 4, and the internal thread of the external thread of sleeve pipe 4 and auger drill head 7 connects and composes.
Auger drill head 7 is provided with interior shoulder, and interior shoulder is supported soil sample box 6, to soil sample box 6 axial limitings.
Every joint soil sample box 6 is isometric with every joint sleeve pipe 4, and every joint soil sample box 6 contacts cooperation with every joint soil sample box 6.
The technical solution of the utility model is: drill pipe sub 1 is connected with drilling rod, drill pipe sub 1 inside is provided with three-way bar water pipe 8, be provided with ball valve 2 in the junction of three-way bar water pipe 8, drill pipe sub 1 lower end is connected with the external thread of sleeve pipe 4 by the internal thread of tail pipe 3, upper casing joint 4 is connected with lower casing joint 4 by connecting pipe 5, and the lower end of sleeve pipe 4 is connected by the external thread of internal thread with auger drill head 7, and auger drill head 7 is provided with interior shoulder, interior shoulder is supported soil sample box 6, to soil sample box 6 axial limitings.Every joint soil sample box 6 is isometric with every joint sleeve pipe 4, and every joint soil sample box 6 contacts cooperation with every joint soil sample box 6.
During sampling, can connect some sections sleeve pipes 4 according to soil thickness, the built-in soil sample box 6 of sleeve pipe 4, soil sample box 6 lengthens with the lengthening of sleeve pipe 4, the long 20cm that is not less than of every joint sleeve pipe 4, soil sample box 6 is isometric with sleeve pipe 4, and upper sleeve pipe 4 is connected by connecting pipe 5 with running casing 4, connects auger drill head 7 in the bottom of casing starter 4.Crept into downwards by drill pipe sub 1 drive sleeve pipe 4 and auger drill head 7 and fetch earth, multistage Rotational Thin wall type soil sample barrel adopts and pierces formula, can better enter soil layer; Water in soil sample box 6 enter in soil sample box 6 with soil sample, wash ball valve 2 open with being pressed into of soil sample, and the pressure of water column to soil sample in rows of openings enters the hole wall gap through top osculum discharge currents, guarantees the taking rate of soil sample.
Fetch earth after end, propose multistage Rotational Thin wall type soil sample barrel, this moment, valve 2 cut out, and hole Nei Shui can not enter soil sample box 6, plays sealing function.Multistage Rotational Thin wall type soil sample barrel is splitted into some sections, take out the soil sample box 6 in ring-shaped sleeve 4, directly approved sample.
