Another purposewith the invention is to provide a device for carrying out the method itselfwhich is simple and efficient to use.
    These objects of the invention are solved by a method which presents themfeatures and characteristics as claimed in claim 1. A device for carrying outthe procedure itself is apparent from the features of claim 4. Furtherfeatures and advantages of the invention are apparent from the subclaims.
    The present invention is described in more detail with reference to an exemplary embodiment whichshown in the accompanying drawings, in which; fl git shows schematically with separated parts in oneLongitudinal section through a device according to the invention, fl gl schematically shows parts ofthe device according to fig. 1 in composite design, fi g¿ shows a perspective view of one in the deviceinput pipe section for collecting a soil sample, fi g._3 shows a cross-sectional view throughthe device viewed along the line lll-lll in Fig. t, fi g._í shows a perspective view throughthe device with partially disassembled parts and carrying out photography, fi gi showsside view of one in the device schematically illustrated with obscured contour lines indicatedcontrol means for joining the two shell-shaped pipe halves which together form an ithe device comprising outer pipes, gg çgg schematically shows how inner pipe sections are taken outthe device is separated from each other to form manageable soil samples.
    Fig. 1a shows with disassembled parts a device for producing soil samplesa strong exteriorsampling tubes 1 of, for example, steel as delimiting an inner circular-cylindrical space 2according to the invention. The device, which is the piston sample type, includescan be spliced to a relatively large length. At the top is in the outer tube 1, via a bayonet socket 3,releasably attached an end cap 4 provided with a projecting holding member 5 for receiving in achuck or the like arranged in a means not shown for driving down the whole device inthe ground. At the bottom, in the outer tube 1, via a bayonet socket 6, an annular attachment is releasably attachedcrown 7 provided with a ground-cutting edge 8 made of something suitable for the purposeabrasion resistant material such as stainless steel or hard metal.The end cap 4 encloses the upper end of the outer tube 1 and is said bayonet socket 3formed with an internal lug 10 for co-operation with a substantially axially directed groove 11 inthe outer tube. Similarly, the annular crown 7 encloses the lower outer tube 1end and is formed with a corresponding bayonet socket 6 in the form of an inner lug 10for co-operation with a substantially axially directed groove 11 in the outer tube. In Fig. 1 onlya heel and groove for said respective bayonet socket 3, 6, but it should be understood thatthere are suitably at least two or more such cooperating parts. Thanks to the aboverespective bayonet socket 3, 6, both the end cap 4 and the crown 7 can be quickly removed fromW: 0ther_Casedocuments PatentlrP409- P40903323SE00 090B19 besk.doc1015202530353the outer tube 1 by the combination of a short rotation followed by an axial pulling movement inoutward direction.
    Between said end cap 4 and the upper end of the outer tube, respectively, annularcrown and the lower end of the outer tube, O-ring type seals 12 are provided. End cap 4is provided with an opening 14 which gas-transmits connects the inner space 2 of the devicewith the surrounding atmosphere. The opening 14 has the task of, as illustrated byarrow 15, allow entrapped air to be discharged as a sample core is formed inside the device.
    In the lower part of the outer tube 1 there is a shutter 16 which is provided with a series radiallyFlexible tongues have the task of retaining a formed test core inside the device bybend inwards and thereby close the outer tube. Hereby it gets into it in the devicepenetrated the sample to be effectively retained in its position when the device is finally pulled outthe ground. The shutter 16 is provided with an annular radially extending flange 17 with which itis retained clamped between the annular crown 7 and the lower end of the outer tube 1. See alsoFig. 1b. Said shutter 16 is well known per se and will therefore not be described in more detail.
    Fig. 2 shows an inner pipe section 20 or sleeve for collecting a respective onetest core. Each inner tube section 20 is assigned a visually visible identification 21 in the form of alabel with a control number, in the exemplary embodiment denoted by Roman numerals l, ll, llletc. The identification is suitably unique to each inner tube so that these can be identified onfor example, a photograph in an established documentation with the pipe sections 20 stilllocated in stack formation in the device. Said inner pipe section 20 each has onelimited length and are intended to be accommodated in the receiving space 1 of the device where theystacked in a series on top of each other form a single long fictitious inner tube whose totaltotal length substantially corresponds to the length of the outer tube 1. Eachof said inner pipe section 20, which are preferably made of plastic material, can be closedat the ends by means of end plugs 22 of some elastomer such as rubber for encapsulation ofa formed sample core.Fig. 1b shows parts of the device in composite design, in which it will be seen in more detailthat the inner tube sections 20, placed in a stack on top of each other in the outer tube 1 of the device,centered in relation to both the outer tube and the crown 7 so that a formed sample corewill extend like a continuous pillar through the stack of inner pipe sections 20. Theof stack formed by inner tube sections 20 supports with some degree of engagement at its upperrespectively lower free end edge against shoulders 23, 23 'formed in the end cap 4 and the crown 7, respectivelyor plan. The intention is that the stack of inner pipe sections 20 should be supported on a retainermethod between said approaches 23. As will be seen in a closer study of Fig. 1bessentially corresponds to the inner diameter d1 of the annular crown 7 with the inner onesinner diameter of the tubes 20 d2. The openings between said parts are concentrically aligned witheach other so that the subsequently formed sample core will extend like a continuous oneW: 0ther_Casedocuments Patent P409- P40903323SE00 090819 besk.doc1015202530354pillars through the long fictitious inner tube formed by the stacked interiorsouterreceiving space 2 has lengths which are so mutually selected that a certain number of inner tubesthe pipe sections. The respective inner tube sections 20 and that tube 1can be accommodated supportively between the shoulders 23, 23 'in the receiving space.
    With reference to tig. 3-5 it appears that the device is provided with a door 30 whichwith a simple grip can be loosened so that the inner pipe sections 20 with it through themcontinuously extending sample core can be removed from the device. Because they stackedthe inner pipe sections 20 should be easy to remove, the device is demountable, whereby itouter tube 1 formed as two longitudinally shell-shaped tube halves 1 '1 "whose oppositeedges are provided with cooperating guide means 31 which allow the two pipe halves todisplaced axially in and out of engagement with each other. To facilitate disassembly yearsthe guide means 31 designed as cooperating hooks 32 and grooves 33 arranged in an even mannerdistributed series spaced apart along the 1, t "of the two pipe halvesfacing edges. The hooks 32 can be lowered into said groove 33 and brought into locking gripby pushing the two halves of the pipe only a short distance into each other so that they lie straightover each other. Thanks to the fact that the parts only need to be pushed a short distance to achieveintervention eliminates the risk of the parts jamming during assembly and disassembly due toany sand and soil particles in the control means.
    In the above-mentioned embodiment, the two tube halves 1 ', t' are connected toeach other securely when in the folded position. The two tube halves 1 ', 1 "arefree to be separated from each other after the crown 7 and the end cap 4 have been detached from theirsrespective bayonet socket with the outer tube. To facilitate division or differentiationof the two tube halves 1 ', 1 "of the outer tube 1, at least one tube half 1' is provided withmounting means 34 such as protrusions, recesses or the like designed to cooperate withany hand tool that offers impact action such as a hammer, chisel or the like.
    As shown in Fig. 6, the device suitably comprises a push rod 35, one of whichend stack of inner pipe sections 20 can be driven longitudinally out of one pipe half 1 ".
    Referring to Fig. 4, the device includes a camera 40 which is suitably offthe kind that is also provided with a date. After sampling, ie.immediately after the device has been pulled out of the ground and opened, they are photographed inthe device accommodates the inner tube sections 20 in the stack so that in an established positiondocumentation must be able to be proven from which sampling and the respective depth a specifictest core is derived. Thanks to the fact that each inner test tube 20 is provided with one visible in a photographidentification 21 or marking, this is possible.
    The device is used as follows:Alternatively, with the crown 7 and the shutter 16 removed, the device was hot disassembledthe device is charged with a series of inner tube sections 20 (without end plugs 22). When disassembledW: 0lher_CasedocumentsWatent P409- P40903323SE00 090B1 9 begrmoc101520255device, the charging preferably takes place with one half of the tube 1 "lying horizontally onthe ground. When all the inner pipe sections 20 have been placed in the correct order in the device, it is closedby bringing the tube halves 1, 1 "together, the shutter 16 and the crown 7 attached to the lower onethe pipe end by means of the bayonet socket 6 and the end cap 7 are fastened in the upper pipe end by means ofbayonet socket 3. After this, sampling is carried out by the device in an appropriate mannerdriven into the ground.
    After sampling, the soil sample is enclosed as an elongated core in itthe outer tube 1 stack of inner tube sections 20. After the soil sample has been taken up to the ground surface andplaced lying substantially horizontally on the ground, the inner pipe sections 20 are thus exposedthat they become visible for photography. By the term "exposed" as used herein is meant thatthe pipe sections are visible or accessible but still located inat least part of the device. Exposure takes place by removing the crown 7 andthe shutter 16 from the lower end of the outer tube 1, the end cap 4 from the upper end of the outer tubeafter which the two tube halves 1 ', 1 ", (one tube half serving as lid 30) are separated fromeach other. Immediately after the tube halves 1 ', 1 "are divided, it is photographed in the deviceoccupied stack of inner tube sections 20 so that it is associated with the respective inner tubethe identification 21 in the form of a label with associated control number appears.
    Thereafter, the entire stack of inner tube sections 20 is driven axially out of one tube half 1 "by means of the push rod 35. The respective inner pipe sections 20 in the removed stackare conveniently carefully separated from each other by means of a thin flexible sheet of steel such as oneputty shovel 41 or similar fixed cutting means where as shown in Fig. 6 onethe tube half 1 'can advantageously serve as a support. Then the respective inner pipe section 20 is pluggedby means of the end plugs 22 so that the respective sample core is securely retained in the respectiveinner tube section 20 for further transport to, for example, the laboratory.
    The invention is limited to what is described above and what is shown in the drawings withoutcan be modified and modified in a number of different ways within the scope of the appended claimsstated inventive idea.
