Description

Outer shoulder inner cone opposite opened plastics soil sample tube
Technical field
The utility model relates to a kind of soil sample tube, particularly a kind of outer shoulder inner cone opposite opened plastics soil sample tube.
Background technology
At present in engineering geological drilling, the soil sample tube is a soil sample barrel when taking soil sample in the stratum, is used to contain the special-purpose vessel of getting the test soil sample.At present, that " the conventional soil sample barrel " of domestic widespread use (Fig. 1) adopts is iron sheet soil sample tube (11 among Fig. 1), it be a kind of be rolled into by galvanized sheet cylindric, but iron sheet tube that will not weld seam.During sampling, iron sheet soil sample tube is installed in two the semicircle pillars that can split in soil sample barrel middle part (12 among Fig. 1).Soil sample barrel is put into boring by the drilling rod that connects, and is exerted pressure in the face of drilling rod by ground, soil sample barrel is pressed into or is driven in the soil layer of prescribed depth at the bottom of the boring hole, adopts into soil sample.And be positioned at this part soil of the iron sheet soil sample tube in the middle part of the soil sample barrel, be used to carry out the soil sample of various mechanics, physical testing exactly.
Owing to the quality of sampling quality, can directly have influence on the quality and the investment cost of engineering design.Therefore when sampling, how to reduce disturbance as far as possible, keep the initial quality (virgin state) of soil sample to greatest extent soil sample, most important to design.
But the iron sheet soil sample tube in " conventional soil sample barrel " but exists and causes all multifactor of soil sample disturbance, thereby has a strong impact on the sampling quality of " conventional soil sample barrel " at present.As: 1, because iron sheet soil sample tube only is one and is rolled into " galvanized sheet " cylindraceous that therefore, it can arbitrary deformation and the neither one fixed shape.When the soil sample tube of having got sample takes out from soil sample barrel because the elasticity of iron sheet tube can flick distortion in the middle of joint close, or when taking because of hand pinching distortion, thereby the disturbance that soil sample is produced.2, galvanized iron sheet soil sample tube will get rusty after using several times very soon.Therefore, in daily production, employed all is corrosion, or even the iron sheet soil sample tube of serious corrosion.And when taking soil sample with the iron sheet soil sample tube of corrosion, the frictional resistance when its coarse inwall can increase soil sample and enters the soil sample tube, thus soil sample is produced disturbance.3, iron sheet soil sample tube is because of the hackly inwall of corrosion, and regular meeting and soil sample bond together.Therefore, in testing laboratory the soil sample tube is pushed aside from commissure, when taking out soil sample, some soil sample of regular meeting sticks on the inwall of soil sample tube, causes soil sample class to refute damaged and disturbance.4, iron sheet soil sample tube is after use for several times and carrying back and forth, and its stack shell often has been out of shape and has no longer just justified, thereby brings disturbance to soil sample.Sometimes when taking pan soil, just the commissure injustice makes one jiao of soil sample that is entered of iron sheet turn over to stick up and rolls because iron sheet tube is not round, is embedded into thoroughly to destroy soil sample in the middle of the soil sample.5, iron sheet soil sample wound packages is in soil sample barrel, being pressed into or being driven into when taking a sample in the soil layer, is to rely on surplus soil tube (14 among Fig. 1) that the edge, upper end (13 among Fig. 1) of iron sheet soil sample tube withstands on soil sample barrel to be fixed on the step (15 among Fig. 1) in the stomidium down.For making the soil sample tube of making by sheet iron, avoid when taking soil sample, being advanced surplus soil tube by sliding on the soil sample.Therefore, the internal diameter of surplus soil tube is less than the internal diameter of iron sheet soil sample tube.Enter surplus when tube soil when soil sample top like this, will because of the aperture of surplus soil tube less than the soil sample diameter, and give soil sample enter the very big resistance of formation, cause the disturbance of soil sample.6, because the increase of above-mentioned resistance the hammering number of soil sample barrel in being driven into soil layer increased, and the increase of hammering number then further strengthens the disturbance to soil sample again.7, since surplus soil tube internal diameter less than the internal diameter of iron sheet soil sample tube, so soil on soil sample top is to get into less than in the surplus soil tube of itself diameter.So when cleaning, these soil just are difficult for being removed.And for many years, method commonly used is exactly by with the surplus soil tube of soil sample barrel and coupled soil sample barrel head (16 among Fig. 1) together, on a preprepared big wooden unit, rams big and heavy stone at full tilt and scratches to dig and take out.Therefore, make surplus soil tube and coupled soil sample barrel head when cleaning, very bother and waste time and energy.
In fact, in the application of " conventional soil sample barrel " many decades,, can cause the disturbance of soil sample well-known for above-mentioned these disadvantages of " conventional soil sample barrel " iron sheet soil sample tube.To this, though also existing hope of eliminating iron sheet soil sample tube for many years always because of its cheap on price, and uses it till today always.
Summary of the invention
The purpose of this utility model is to solve the existing disadvantage of soil sample tube of the prior art, provides a kind of and can reduce the soil sample disturbance greatly, uses outside the very convenient labour-saving of cleaning of back soil sample barrel to take on inner cone opposite opened plastics soil sample tube.The outer shoulder of the utility model design inner cone opposite opened plastics soil sample tube, comprise that splitting is two plastics semicircular cylinder, it is characterized in that: on the semi circular surface of semicircular cylinder outside, laterally be provided with an arcuation crossette concentric with semicircular cylinder, the inwall of semicircular cylinder has axial gradient.The arcuation crossette is positioned at plastics semicircular cylinder outside.The arcuation crossette has spacing at the commissure of two semicircular cylinders, and there is spacing at arcuation crossette and plastics soil sample tube two ends.The upper inside wall radius of semicircular cylinder is greater than the lower inner wall radius.The inwall of semicircular cylinder is a shiny surface.The utility model has the advantages that: 1, adopt plastic production soil sample tube, its level and smooth barrel has reduced the frictional resistance when soil sample enters the soil sample tube, thereby has also reduced the disturbance to soil sample.2, stack shell is level and smooth stainless makes it can bonding and destruction or disturbed sample not take place with soil sample.Cleaning when also having made things convenient for the soil sample tube to reuse.3, the fixed in shape of stack shell can arbitrary deformation and soil sample is produced disturbance.4, the soil sample tube makes the surplus soil tube internal diameter of soil sample barrel can be greater than the external diameter of soil sample tube by the arcuation crossette, and the inwall of surplus like this soil tube does not just come in contact the soil sample that enters in it, thereby has thoroughly eliminated the disturbance of surplus soil tube to soil sample.5, because surplus soil tube internal diameter greater than soil sample tube external diameter, makes soft, the stiff clay that enters in the surplus soil tube can both be at an easy rate one fall and go out, make the removing of surplus soil and clean simple and direct laborsaving.6, two semicircular cylinder inner wall belts are gradient, make synthetic soil sample tube endoporus, form one and have the little down bellmouth of big slight taper.Therefore, when soil sample entered the soil sample tube, its whole traveling process was ascending, thus greatly reduce soil sample when entering the soil sample tube frictional resistance and reduce the soil sample disturbance.7, the arcuation crossette reaches between arcuation crossette and soil sample cover between the joint close of two semicircular cylinders, leaves the spacing of certain width.Thereby make things convenient for the stickup of approved sample adhesive tape, help the sealing of soil sample.And make soil sample tube up and down two lid uniform specification and convenient the use.8, plastics soil sample tube does not have sharp keen corner and iron rust, helps handling safety.9, the soil sample tube adopts that the full circle tube is split is two semicircular cylinder form, can make things convenient for the taking-up of soil sample.And avoid the soil sample tube of full circle cartridge form, need to release a soil sample in the tube with bulldozing device, and twice disturbance that brings to soil sample.10, plastics soil sample tube not only has the same cheap price of iron sheet soil sample tube, and has longer serviceable life, promotes and help substituting.
