Abstract
The invention discloses sampling equipment of silt and soft soil. The sampling equipment of the silt and the soft soil comprises a sampling device and a static force pressing and lifting device which is detachably connected with the sampling device, wherein the sampling device comprises a vertically arranged sampling thin-walled pipe and a valve which is arranged on a sampling thin-walled pipe; the valve comprises a valve body which is directly connected with the sampling thin-walled pipe through an internal thread and a cock body which is connected with the valve body in a rotational mode; and a pulling ring which is connected with a pulling rope is arranged on the cock body in fixed connection. Basically disturbance is not caused to samples in a down-sampling process of a thin-walled pipe due to the facts that a sampling process is performed through the thin-walled pipe and the valve is arranged at the upper end of the thin-walled pipe. After the down-sampling process of the thin-walled pipe is achieved, the valve is closed, and the upper end of the thin-walled pipe is sealed to form vacuum; the thin-walled pipe is lifted, an undisturbed sample performs upward movement with the thin-walled pipe, and the sample is obtained. The sampling equipment of the silt and the soft soil has the advantages of being small in disturbance to the slit and slit soil in the entire sampling process and capable of obtaining a primary undisturbed sample and a secondary undisturbed sample.
Description
Technical field
The present invention relates to a kind of sampling equipment, particularly the sampling equipment of a kind of mud and weak soil.
Background technology
In reclaiming land around sea and training of river channel desilting engineering, can form a large amount of hydraulic reclamation district and mire, in this zone neither simple mud, water that neither be simple, but mud mixture become stream to mould state, have very high moisture content and very low intensity, the hydraulic reclamation soil's water content is large, surpasses 100%.Under such geological conditions, boats and ships can not navigate by water in the above, vehicle more can't travel in the above, if need under such geological conditions, fetch earth, conventional drilling equipment is because own wt is larger, can't work thereon, even can float on the mud face by the form of setting up floating drum, but that it moves is also very difficult.So be badly in need of developing a kind of novel light borrow equipment that the saturated dredger soft soil district fetches earth that is applicable to, this equipment should have simple to operate, light characteristics, can be freely movable in the saturated dredger soft soil district, and should be able to obtain high-grade undisturbed soil sample.
Summary of the invention
The present invention for solve saturated dredger soft soil district, mire district or under water the problem of sampling of ooze provide a kind of can be mobile flexibly thereon, and can obtain the sampling equipment of high-grade undisturbed.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: the sampling equipment of a kind of mud and weak soil, comprise sampler and be pressed into and lifting appliance with the static(al) of described sampler by releasable connection, described sampler comprises the sampling light-wall pipe of vertical setting and is arranged on the valve of described sampling light-wall pipe upper end, described valve comprises with described sampling light-wall pipe by the direct-connected valve body of internal thread and the faucet body that is rotationally connected with described valve body, be connected with draw ring on the described faucet body, be connected with stay cord on the described draw ring.
Described static(al) be pressed into be connected with lifting appliance support, with described valve body by the affixed vertical connecting rod of jointing, horizontal supporting plate, the driving-chain that with horizontal supporting plate be connected and the drive sprocket that with driving-chain be connected affixed with described vertical connecting rod, described drive sprocket is fixed on the horizontal rotating shaft, described horizontal rotating shaft is bearing on the described support, and described horizontal rotating shaft is connected with rocking bar by chain-drive mechanism; Described vertical connecting rod is slidingly connected on the described support.
The lower end of described sampling light-wall pipe is provided with the basil.
Advantage and good effect that the present invention has are: establish valvular light-wall pipe sampling by the upper end, during sampling, make valve be in opening, allow soil sample current up and down; the basil to be arranged on the light-wall pipe, in the descending sampling process of light-wall pipe, substantially sample is not formed disturbance.After light-wall pipe is finished descending sampling, valve-off, the upper end sealing with light-wall pipe forms vacuum; On carry light-wall pipe, undisturbed will move upward together along with light-wall pipe, realizes obtaining sample.Whole sampling process is very little to mud and mucky soil disturbance.Avoided conventional probing disturbance and conventional thin-wall sampler to the bottom soil layer in pore forming process in the engineering that fetches earth, may to the extruding of soil sample generation, can obtain the firsts and seconds undisturbed sample.The principle of the invention is clear, simple in structure, lightweight, and is easy and simple to handle, and efficient is high, and good stability is adapted at carrying out sampling work under the environment that the conventional rigs such as hydraulic reclamation district that hydraulic reclamation forms and mire can't work.Be equipped with the instruments that travel such as aircushion vehicle, can be implemented in hydraulic reclamation district and the mire zone that hydraulic reclamation forms and carry out doing from the sampleman that travels, be applicable to soft mould and stream is moulded taking of shape mud undisturbed.Also can be used for taking of seabed or silt from the bottom of lake soil sample.

Fig. 1 is structural representation of the present invention.
Among the figure: 1, rocking bar, 2, chain-drive mechanism, 3, rotating shaft, 4, the vertical connecting rod, 5, support, 6, driving-chain, 7, horizontal supporting plate, 8, stay cord, 9, draw ring, 10, get the mud light-wall pipe, 11, valve body, 12, faucet body, 13, earth anchor.
The specific embodiment
For further understanding summary of the invention of the present invention, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1, the sampling equipment of a kind of mud and weak soil, comprise sampler and be pressed into and lifting appliance with the static(al) of described sampler by releasable connection, described sampler comprises the sampling light-wall pipe 10 of vertical setting and is arranged on the valve of described sampling light-wall pipe 10 upper ends, described valve comprises with described sampling light-wall pipe 10 by the direct-connected valve body 11 of internal thread and the faucet body 12 that is rotationally connected with described valve body 11, be connected with draw ring 9 on the described faucet body 12, be connected with stay cord 8 on the described draw ring 9.
In the above-described embodiments, described static(al) be pressed into be connected with lifting appliance support 5, with described valve body 11 by the affixed vertical connecting rod 4 of jointing, horizontal supporting plate 7, the driving-chain 6 that with horizontal supporting plate 7 be connected and the drive sprocket that with driving-chain 6 be connected affixed with described vertical connecting rod 4, described drive sprocket is fixed on the horizontal rotating shaft 3, described horizontal rotating shaft 3 is bearing on the described support 5, and described horizontal rotating shaft 3 is connected with rocking bar 1 by chain-drive mechanism 2; Described vertical connecting rod 4 is slidingly connected on the described support 5.For be conducive to get the descending of mud light-wall pipe 10 and on carry, the lower end of described sampling light-wall pipe 10 is provided with the basil.
