Abstract

The utility model discloses a folio coring penetration sounding device, comprising an automatic hammer dropping device, a folio coring explosion rod, a buckling device, a folio sampling probe and a rod pulling device. Each of the folio coring explosion rod and the folio coring probe comprise two hollow half-cylinders; one side of each hollow half-cylinder is provided with a groove and the other side thereof is provided with a convex strip so that the two hollow half-cylinders are matched together and can slide along axial direction mutually; and the buckling device is positioned on the folio coring explosion rod and used for buckling the two hollow half-cylinders together. The device has the following advantages that: continuous coring can be executed with multiple meters; the folio coring penetration sounding device is accurate, vivid, quick, light, and is not influenced by electromagnetic interference; the exploration and the detection that the conventional exploration equipment is hard to position the area or the low water area soil layer can be accomplished with low cost; the depth boundary precision of the stratum reaches 0.10m; the history that the conventional power penetration sounding only can indirectly and roughly deduce the stratum boundary is changed.

Description

Split and get the core detector

Technical field

The utility model relates to a kind of equipment of exploring shallow soil layer, and especially a kind of splitting got the core detector.

Background technology

At present, in geotechnical investigation, ground detection, geophysical exploration and archaeology exploration, (1) electromagnetism, water body and mud serious interference following problem often appear:; (2) make that because of the place is narrow conventional survey equipment is difficult to work; (3) the unusual position positioning accuracy of physical prospecting delineation is low; (4) the dynamic sounding exploration can only be inferred the stratum indirectly, and the exploration error is bigger; (5) conventional rig probing destructible historical relic; (6) conventional survey with usually detect the cost height, labour intensity is big.

The utility model content

The purpose of this utility model provides a kind of splitting of being applied to use in geotechnical investigation, ground detection, geophysical exploration and the archaeology exploration and gets the core detector, its advantage be low-cost, efficiently finish the exploration of stenosis area or shallow water area soil layer, can directly observe soil sample, significantly reduce the engineering geophysics error, equipment is light, depth of stratum precision height is specially adapted to the place is narrow, conventional survey equipment is difficult to zone in place soil layer exploration and detection.

For achieving the above object, of the present utility model splitting got the core detector and comprised splitting and get core sounding rod, gripping mechanism and split sampling probe, described splitting got the core sounding rod and split sampling probe and all be made up of two hollow semicolumns, one side of each hollow semicolumn is provided with groove, opposite side is provided with raised line, make two hollow semicolumns cooperatively interact together, and can slide mutually vertically; Described gripping mechanism is positioned to split to be got on the core sounding rod, is used for two hollow semicolumns are snapped together.

Preferably, the upper end of the raised line of described hollow semicolumn is bigger than following end section, and the opening of corresponding grooves matches with the raised line shape less than the bottom surface, and two hollow semicolumns can not separated easily.

Preferably, described gripping mechanism is a sleeve that is provided with internal thread, and the described two ends of getting the core feeler lever of splitting are provided with external screw thread, matches with sleeve, when two hollow semicolumns slip off, the joint of two hollow semicolumns is snapped together.

Preferably, described splitting got the core sounding rod and is threaded with sampling probe.

Preferably, the described feeler lever of getting the core detector split is got core and is visited feeler lever and be formed by connecting by two above-described splitting, and is used to increase the length of getting the core feeler lever.

Preferably, the described sampling probe of splitting is circular blunt mouthful, can avoid damaging underground historical relic like this.

Preferably, described splitting got the core detector and also comprised the device that drops hammer automatically, and the described device that drops hammer automatically comprises punching hammer, pallet and punching bar, is used for getting the core feeler lever and applying the power that creeps into downwards to splitting.

Preferably, described splitting got the core detector and also comprised rod-pulling device, is used for pulling out in soil splitting to get the core sounding rod and split sampling probe.

Preferably, described rod-pulling device is the hand-held rod that dead man card pad or two ends have handle.

The advantage of getting the core detector of splitting that the utility model provides is, (1) is split and got core and visit feeler lever and can slide relatively, uses gripping mechanism to be fixed, thus the length of regulating feeler lever; Splitting more than two can also be got core and visit feeler lever and couple together and increase the length of feeler lever, can be used under water or the exploration and the detection of narrow zone soil layer; (2) device that drops hammer automatically is housed on the feeler lever, for detection provides power; (3) bottom of splitting sampling probe is circular blunt mouthful, helps protecting underground historical relic.

Of the present utility model split get the core detector can many meters continous samplings, accurately, intuitively, quick, light, be not subjected to electromagnetic interference and finish conventional survey equipment inexpensively to be difficult to the exploration of zone in place or shallow water territory soil layer and to detect, depth of stratum boundary line precision reaches 0.10 meter, and it has changed in the past dynamic sounding can only infer the history of stratigraphic boundary indirectly roughly.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

As shown in Figure 1, of the present utility model splitting got the core detector and comprised and split sampling probe 1, split and get core sounding rod 2, be arranged on and split the screw thread circuit 3 of getting core sounding rod 2 two ends, pallet 4, punching hammer 5 and punching bar 6, splitting sampling probe 1 top is provided with internal thread and is threaded with screw thread circuit 3, splitting the upper end of getting core sounding rod 2 is threaded with pallet 4, pallet 4 is provided with punching bar 6, and punching bar 6 is provided with punching hammer 5.This is split and gets splitting of core detector and get and can establish the chucking sleeve on the core sounding rod 2 to increase feeler lever length simultaneously, and the described head of splitting sampling probe is circular blunt mouthful.
