Description
Technical field
The present invention relates to a kind of portable original position high-moisture percentage fluidised form weak soil, mud and mud original state appearance ST and sampling method thereof that in mud stockyard, hydraulic reclamation epeirogenetic place and rubbish Treatment of Sludge place, uses; Be to be directed to rare plastic flow attitude soil property situation that mud stockyard, blast-filled ground and Treatment of Sludge place occur especially and the light-duty in-situ test instrument that designs belongs to correlative technology fields such as Geotechnical Engineering and environmental engineering on depth direction.
Background technology
In training of channel desilting engineering, the engineering of reclaiming land from the sea and rubbish mud landfill engineering, all can run into the solidification problem of the high-moisture percentage soil body.For the place that has high-moisture percentage mud, if the impeded drainage in place or hydraulic reclamation soil body clay content are higher, then consolidation settlement will be a very long process.In the middle of this very long process; Through the surface evaporation of exposing to the weather for a long time, can form the thicker crust layer of one deck on the soil layer surface, be mingled with herbal rhizome residue; Make veneer of soil have certain apparent intensity; But the most engineering monitoring result shows that the soil body is still keeping very high water percentage at underground certain depth place, or even a kind of semifluid form near original state; Though the top layer soil body has certain intensity and can the pedestrian, some small-sized boring mechanics are difficult to get into the place, more need not carry big machinery.Carry out the project of further engineering and the expropriation of land engineering of second ploughing as early as possible for the land used of being eager, being difficult to of these engineering place geotechnical investigations is the problem of restriction.Conventional boring with sampling method is not suitable for above-mentioned place; The one, because boring mechanic is too heavy, the soil layer surface is held and can't stand such weight, and the 2nd, promptly enable to take out the globality sample; Original architectural feature also can take place to flow and destroy in transportation; Particularly in the process of mud sampling, the mud concentration of narmful substance of different depth will change, and causes the inaccurate of environmental hazard assessed information.Add the original position soil test that some are commonly used, all need the engineer geological prospecting in early stage like standard penetration test (SPT), four-bladed vane test, static sounding etc. with better reliability and accuracy.So be badly in need of developing a kind of light-duty portable sample apparatus that obtains original state appearance in can mud layer in mud stockyard, blast-filled ground and rubbish Treatment of Sludge place, to solve problem actual in the engineering in rare soft flow.
Summary of the invention
Goal of the invention: in order to overcome the deficiency that exists in the prior art; The present invention proposes a kind of many degree of depth sealing STs of runner and corresponding sampling method that can in rare ooze layer in mud stockyard, blast-filled ground and rubbish Treatment of Sludge place, carry out boring with sampling; To solve the sampling shop problem when other large-scale boring mechanics can't get into the place; Provide sampling result, for engineering provides reliable geological physical chemistry data.
Technical scheme: for solving the problems of the technologies described above, the many degree of depth sealings of a kind of runner of the present invention ST comprises sampling holding rod, cylinder storage appearance nest, sealed cylindrical and the rotation holding rod of being with draw-in groove; The middle part of described sampling holding rod is provided with annular slot, and sampling holding rod lower end is connected with cylinder storage appearance nest, and described cylinder storage appearance nest is the structure of the onesize storage appearance groove of offering of cylindrical solid side equidistance; It is separated that adjacent storage appearance groove leaves inter-entity; Cylinder storage appearance lower end, nest connects the circular cone drill head, and described sealed cylindrical is the cylinder thin-wall construction of an end face opening one end sealing, and the sealed cylindrical internal diameter equates with cylinder storage appearance nest external diameter; The sealed cylindrical side has a rectangular aperture; Said rectangular aperture width is fixedly connected the rotation holding rod less than the separated width of inter-entity of cylinder storage appearance nest above the sealed cylindrical, rotation holding rod internal diameter and sampling holding rod equal diameters; Rotation holding rod side is provided with deep calibration; Rotation holding rod top is provided with the ring spring buckle that matches with annular slot, and described sealed cylindrical links together with the rotation holding rod and constitutes the rotary sleeve tube, and described circular cone drill head, cylinder storage appearance nest and sampling holding rod link together and constitute rotary-type storage kind nest; The rotary sleeve tube is placed in outside, rotary-type storage appearance nest from top to bottom, and uses the ring spring snap fit.
As preferably, described sampling holding rod, cylinder storage appearance nest and circular cone drill head are from top to bottom along center line alignment welding; Described sealed cylindrical and rotation holding rod are along the center line welding of aliging.
In the present invention, a kind of sampling method based on the many degree of depth sealings of runner ST may further comprise the steps:
1) the rotary sleeve tube is placed in outside, rotary-type storage appearance nest from top to bottom, the ring spring buckle is buckled in the annular slot of the sampling holding rod of being with draw-in groove, make sealed cylindrical that a cylinder storage appearance nest is entangled fully;
2) rotate the rotation holding rod, make the rectangular aperture of sealed cylindrical side rest on the interval between the cylinder storage appearance nest storage appearance space, make the storage appearance space of all cylinder storage appearance nests all be sealed;
3) the many degree of depth sealings of runner ST is placed to predetermined probing point, excavates the crust layer of muck surface;
4) push ST downwards, read the deep calibration on the rotation holding rod sidewall, ST is pressed into predetermined depth in the soil body;
5) rotate the rotation holding rod, make the rectangular aperture of sealed cylindrical side turn to first place, cylinder storage appearance nest storage appearance space, rare soft mud soil sample is flow in the storage appearance space, continue along equidirectional rotation rotation holding rod, first storage appearance space sealing;
6) continue to push ST downwards, arrive second sampling depth, rotate the rotation holding rod; Open second cylinder storage appearance nest storage appearance space; Rare soft mud soil sample is flow in the storage appearance space, continue along equidirectional rotation rotation holding rod, second storage appearance space sealing;
7) step continues sampling according to this, after the soil sample on all degree of depth has been got, on promote out ST to leave the soil body;
When 8) extracting soil sample, counter-rotation rotation holding rod, is sampled to preceding storage appearance space of exposing the cylinder storage appearance nest of different depth successively from the back again.
Beneficial effect: the many degree of depth of runner of the present invention sealing STs and sampling method thereof can overcome the shortcoming that original state appearance water percentage, physicochemical characteristic change easily when the place sampling that has the rare plastic flow attitude of high-moisture percentage mud layer; And the characteristics of this ST lightweight, portable can make it carry under the hypodynamic situation at weak soil, mud place and rubbish sludge landfill ground surface to use; The many degree of depth sealings of runner ST adopts modular design, can disposablely take a sample at different depth place, same place, accurately controls sampling depth, and sampling amount can be guaranteed simultaneously.ST equipment is simple, and lightweight is easy and simple to handle, and efficient is high, and the sampling cost is low, and is little to the disturbance in sampling place.
