Fig. 2 is the utility model L-type dedicated tool sampling schematic diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is described in more detail.
With reference to Fig. 1, a kind of static pressure type drawing out soil equipment mainly is comprised of infeed mean, buffer unit, guiding parts, firm parts four parts in location, and described infeed mean jams on power biography cylinder 1 by single pin and consists of; Described buffer unit is made of secondary spring 2; Described guiding parts is made of guide-localization sleeve 3; Described positioning stablity parts are comprised of base 7 and locating steel needle 4; Described single pin jams on power biography cylinder 1 and is arranged in the guide-localization sleeve 3, can be free to slide, and fit system is matched in clearance, and the external diameter that single pin jams on power biography cylinder 1 is identical with the internal diameter of guide-localization sleeve 3, and section equals the external diameter of secondary cutter 5, cutting ring 6; Guide-localization sleeve 3 adopts with base 7 and is threaded, and is provided with external screw thread at guide-localization sleeve 3, but the screw-in depth of free adjustment guide-localization sleeve 3 on base 7; Locating steel needle 4 adopts with base 7 and is threaded, and can determine whether install according to on-the-spot sandy soil situation.Be welded with four hand steered support bar hold-down nuts 8 at base 7, model is the M20 nut.Fixing hand steered devices such as the stay bolt of M20 or band external screw thread steel pipe, rod iron, effect is when the larger aeolian sand subgrade of degree of compaction is taken a sample, for the hand steered application of force of field sampling personnel.
The internal diameter 60mm of described cutting ring 6, high 52mm, wall thickness 1mm, volume 150cm
3Described secondary cutter 5 internal diameter 60mm, wall thickness 1mm, high score are 50mm, 40mm, three kinds of models of 30mm.
As shown in Figure 2, the utility model also comprises the L-type dedicated tool, and described L-type dedicated tool is comprised of 70*70mm steel disc and 150mm handle.
The utility model static pressure type drawing out soil equipment is to aim at the special-purpose taking soil working tool that the aeolian sand subgrade degree of compaction detects development, be applicable to drift-sand sample or the similar drift-sand sample of compacting, when concrete the application, when the detection of degree of compaction, the empty layer in drift-sand surface was shoveled the smooth compacting detection layers of exposing surface.With drawing out soil equipment perpendicular alignmnet compacting center, place steadily.Regulate abutment sleeve 3, make it and the native Surface Contact of base.The tester directly puts into guide-localization sleeve 3 with cutting ring 6.Determine whether as required to use secondary cutter 5 and model thereof.Secondary spring 2 is enclosed within pedal pressure passes on the cylinder 1, again it is positioned in the positioning and guiding sleeve 3.The single pin of testing staff steps down on the foot rest of pressure biography cylinder 1, and cutting ring 6 slowly is pressed in the basic soil.Remove drawing out soil equipment, dig pit in the cutting ring side with the L cutter and end to the cutting ring bottom, L cutter plug flat is entered the cutting ring bottom, then upwards extract the cutting ring sample.Draw together the unnecessary sample of decyclization cutter end face with drawing together cutter, the cutting ring that then overturns is drawn together the unnecessary sample in bottom surface.Use the 500g-1000g balance, take by weighing the husky sample weight of cutting ring, detect water content, calculate degree of compaction, finish the compactness test testing process.
The using method of L-type dedicated tool: in actual sampling operation process, the correct L-type dedicated tool that uses, can guarantee successfully to obtain soil sample, its method of operating is to dig pit in the cutting ring side to the cutting ring bottom, again the L-type dedicated tool is entered from the bottom plug flat, rear extraction cutting ring, at this moment blade has just sealed the cutting ring bottom surface, makes it that end leakage not occur.
The above; it only is the better specific embodiment of the utility model; protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses, the simple change of the technical scheme that can obtain apparently or equivalence are replaced and are all fallen in the protection domain of the present utility model.
