Abstract
The invention discloses 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 that vertical is arranged and the valve being arranged on described sampling light-wall pipe upper end, described valve comprises the valve body be directly connected by internal thread with described sampling light-wall pipe and the faucet body be rotationally connected with described valve body, described faucet body is connected with draw ring, described draw ring is connected with stay cord.The present invention establishes valvular light-wall pipe to sample by upper end, in the descending sampling process of light-wall pipe, substantially do not form disturbance to sample.After light-wall pipe completes descending sampling, valve-off, seals the upper end of light-wall pipe, forms vacuum; On carry light-wall pipe, undisturbed will move upward together along with light-wall pipe, realizes the acquisition to sample.Whole sampling process to mud and mucky soil disturbance very little.Firsts and seconds undisturbed sample can be obtained.
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, a large amount of hydraulic reclamation districts and mire can be formed, neither simple mud in this region, water that neither be simple, but mud mixture, become liquid-plastic state, have very high moisture content and very low intensity, hydraulic reclamation soil's water content is large, more than 100%.Under such geological conditions, boats and ships can not navigate by water above, vehicle more cannot travel above, if need to fetch earth under such geological conditions, conventional drilling equipment due to own wt larger, cannot work thereon, even if can be floated on mud face by the form setting up floating drum, but it moves also very difficult.Therefore be badly in need of developing a kind of novel light borrow equipment being applicable to fetch earth in saturated dredger soft soil district, this equipment should have simple to operate, light feature, can be freely movable in saturated dredger soft soil district, and should be able to obtain high-grade undisturbed soil sample.
Summary of the invention
The present invention be solve saturated dredger soft soil district, mire district or under water ooze problem of sampling and provide one can movement flexibly thereon, and the sampling equipment of high-grade undisturbed can be obtained.
The technical scheme that the present invention takes for the technical problem existed in 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 that vertical is arranged and the valve being arranged on described sampling light-wall pipe upper end, described valve comprises the valve body be directly connected by internal thread with described sampling light-wall pipe and the faucet body be rotationally connected with described valve body, described faucet body is connected with draw ring, described draw ring is connected with stay cord.
The press-in of described static(al) and lifting appliance comprise support, with described valve body by affixed vertical connecting rod, the horizontal shelf affixed with described vertical connecting rod, the driving-chain be connected with horizontal shelf and the drive sprocket be connected with driving-chain of jointing, described drive sprocket is fixed on horizontal rotating shaft, on the bracket, described horizontal rotating shaft is connected with rocking bar by chain-drive mechanism in described horizontal rotating shaft supporting; Described vertical connecting rod is slidably connected on the bracket.
The lower end of described sampling light-wall pipe is provided with the basil.
The advantage that the present invention has and good effect are: establish valvular light-wall pipe to sample by upper end, during sampling, make valve be in opening, allow soil sample to pass through up and down; light-wall pipe has the basil, in the descending sampling process of light-wall pipe, substantially disturbance is not formed to sample.After light-wall pipe completes descending sampling, valve-off, seals the upper end of light-wall pipe, forms vacuum; On carry light-wall pipe, undisturbed will move upward together along with light-wall pipe, realizes the acquisition to sample.Whole sampling process to mud and mucky soil disturbance very little.Avoid conventional probing fetching earth in engineering to the extruding of soil sample generation, may can obtain firsts and seconds undisturbed sample to the disturbance of bottom soil layer and conventional thin-wall sampler in pore forming process.The principle of the invention is clear, structure is simple, lightweight, and easy and simple to handle, efficiency is high, good stability, carries out sampling work under being adapted at hydraulic reclamation district that hydraulic reclamation formed and the environment that the conventional drill such as mire cannot work.Being equipped with aircushion vehicle etc. and travelling instrument, the hydraulic reclamation district that formed at hydraulic reclamation can being realized and mire region carries out doing from travelling sampleman, be applicable to soft moulding and the taking of current-formed silt undisturbed.Also can be used for taking of seabed or silt from the bottom of lake soil sample.

Detailed description of the invention
For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to 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 that vertical is arranged and the valve being arranged on described sampling light-wall pipe 10 upper end, described valve comprises the valve body 11 be directly connected by internal thread with described sampling light-wall pipe 10 and the faucet body 12 be rotationally connected with described valve body 11, described faucet body 12 is connected with draw ring 9, described draw ring 9 is connected with stay cord 8.
In the above-described embodiments, the press-in of described static(al) and lifting appliance comprise support 5, with described valve body 11 by affixed vertical connecting rod 4, the horizontal shelf 7 affixed with described vertical connecting rod 4, the driving-chain 6 be connected with horizontal shelf 7 and the drive sprocket be connected with driving-chain 6 of jointing, described drive sprocket is fixed on horizontal rotating shaft 3, described horizontal rotating shaft 3 is bearing on 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 slidably connected on described support 5.In order to be conducive to getting 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.
When sampling in saturated dredger soft soil district, directly static(al) press-in and lifting appliance can be fixed on the ground, adopting earth anchor 13 to support, also can be fixed on aircushion vehicle or other traveling instrument be applicable to.When carrying out mire region, the taking of seabed or silt from the bottom of lake sample, static(al) press-in and lifting appliance can be fixed on boats and ships, aircushion vehicle or other applicable traveling instrument.
Operating principle of the present invention:
