Embodiment
In conjunction with following specific embodiments and the drawings, the present invention is described in further detail.Implement process of the present invention, condition, experimental technique etc., except the following content mentioned specially, be universal knowledege and the common practise of this area, the present invention is not particularly limited content.
See Fig. 1, Fig. 2 and Fig. 3, Fig. 1 display be the schematic diagram of the novel cutting ring of the present invention.Fig. 2 display be the sectional view in A-A cross section in Fig. 1, Fig. 3 display be the vertical view of novel cutting ring, this novel cutting ring comprises into cylindrical shape and coaxial internal layer cutter hub 1, middle level cutter hub 2 and the outer cutter hub 3 arranged.The overall height of novel cutting ring is designed to several different class, and the internal diameter of internal layer cutter hub 1, middle level cutter hub 2 and outer cutter hub 3 is also designed to multiple different size.According to soil texture situation, select the cutting ring of suitable inner diameter.When the soil texture is soft, select the cutting ring that internal diameter is larger; When the soil texture is comparatively glutinous hard, then selects the cutting ring that internal diameter is less, so that insert soil, obtain earth pillar sample.
Internal layer cutter hub 1 is made up of two semi-cylindrical shaped stainless steel substrates, after two stainless steel substrates merge, is provided with in the position of contact the jog cooperatively interacted.Fig. 4 a-c shows three kinds of different jogs, and jog engages each other and two stainless steel substrates are interconnected, and fixes with bolt.Before novel for the present invention cutting ring is inserted soil, two semi-cylindrical shaped stainless steel substrates are engagement state, and are screwed, take out wherein earth pillar time open separation.
Before whole novel cutting ring inserts soil and lift out in the process in soil cave, internal layer cutter hub 1 and outer cutter hub 3 remain connection, and fix in top screw fashion.From soil, take out preparation at novel cutting ring to take out wherein before earth pillar, be separated after opening the screw between internal layer cutter hub 1 with outer cutter hub 3.Fixed screw between two stainless steel substrates opening internal layer cutter hub 1, therefrom extracts earth pillar sample.
Outer cutter hub 3 is set in the outside of internal layer cutter hub 1, and the bottom of outer cutter hub 3 has the gathering portion 31 of the inward collapsible of arc, so that insert in soil.Annular slot 4 is formed between the bottom of gathering portion 31 and internal layer cutter hub 1.
Middle level cutter hub 2 is slidably disposed between internal layer cutter hub 1 and outer cutter hub 3, and the bottom of middle level cutter hub 2 has the cutting knife portion 21 of the inward collapsible of arc.Cutting knife portion 21 is consistent with the radian in gathering portion 31.When sampling, when described middle level cutter hub 2 slides into bottom, described cutting knife portion 21 leans out from described annular slot 4, the soil column and extraneous soil of clamp-oning internal layer cutting ring are cut off, and being enclosed within the cutting ring of middle level, the edge of a knife bottom described cutting knife portion 21 is completely integrated, and sees Fig. 5.In preferred embodiment of the present invention, the inwall of outer cutter hub 3 is provided with at least one sliding tray 32, and the outer wall of middle level cutter hub 2 is provided with the sliding part 22 cooperatively interacted with sliding tray 32.Middle level cutter hub 2 can slide up and down between internal layer cutter hub 1 and outer cutter hub 3 along sliding tray 32.
As shown in Figure 6, the top of middle level cutter hub 2 can be connected with external handheld component 5.The top of middle level cutter hub 2 is provided with screw thread mouth, can be connected threadably with handheld component 5 and fix.To engage with the main body of middle level cutter hub 2 when handheld component 5 and push soil completely, and handheld component 5 upper limb is when flushing with ectonexine cutter hub 3 upper end, the cutting knife portion 21 of middle level cutter hub 2 docks just, thus the soil of internal layer cutter hub 1 inside is cut off with extraneous soil, is separated, and the earth pillar sample sealing middle level cutter hub 2 inside prevents lower leakage.At this moment can the upper limb of handheld parts 5 upper limb and ectonexine cutter hub 3 be screwed.Then novel cutting ring entirety is lifted out.Handheld component 5 can be nested with middle level cutter hub, and the used time can void not put, tighten the screws during use.
See Fig. 7, the cutting knife portion 21 of middle level cutter hub 2 is provided with a thin socket 6, can insert one piece of diaphragm plate in socket 6.Socket 6 surrounding outside two and half intercept form arc cutters, is provided with shallow and caves in uniformly, the degree of depth of this depression and the thickness of length and width size and stainless steel mounting and length and width consistent size.Before novel cutting ring inserts soil and novel cutting ring by the process that lifts out from soil, adopt stainless steel mounting seal socket 6 and fix with screw fashion.After novel cutting ring entirety inserts soil, middle level cutter hub 2 slides into bottom, and when the edge of a knife in cutting knife portion 21 is completely integrated, socket 6 flushes with internal layer cutter hub 1 lower edge just.When novel cutting ring is lifted out and prepares to open internal layer cutter hub 1 from soil, in socket 6, insert diaphragm plate the earth pillar sample in internal layer cutter hub 1 is separated from middle level cutter hub 2, complete continuous print earth pillar sample can be formed.
In order to make the novel cutting ring in insertion soil cave be easy to be lifted out, as shown in Figure 8, the wall of outer cutter hub 3 is offered at least one air channel 7, upper end open is at the top of outer cutter hub 3 wall, and the bottom of air channel 7 is sealing.The lateral wall of outer cutter hub 3 at least arranges a fine through holes 8, and fine through holes 8 is communicated with air channel 7.Before novel cutting ring entirety is lifted out from soil cave, novel cutting ring outer wall and Soil Surrounding may be fitted closely, be not easy to pull-out, at this moment, utilize gas cylinder, inflated in air channel 7 by the hole at outer cutter hub 3 top, blow fine through holes 8 open, make the gas being filled with high flow rate between outer cutter hub 3 and soil contact, resistance when carrying on reducing with this between outer cutter hub 3 and soil contact.
After novel cutting ring entirety is lifted out, first internal layer cutter hub 1 is separated with outer cutter hub 3, internal layer cutter hub 1 and middle level cutter hub 2 are lifted out.After inserting diaphragm plate to socket 6, longitudinally open two semi-cylindrical stainless steel substrates of internal layer cutter hub 1, the soil below diaphragm plate, beyond internal layer cutter hub 1 is removed, obtains the inner complete continuous print earth pillar sample of internal layer cutter hub 1.
When soil comparatively consolidation time, novel cutting ring be inserted into soil process can by machinery or motor come.Three unit-combination type lifting jack such as can be used to assist insertion, two unit-combination type lifting jack assistance lifts.Two unit-combination type lifting jack are common hydraulic jack, and last force direction upwards, assists to lift novel cutting ring from soil cave; And the lifting jack that three unit-combination type lifting jack are made up of three parts.Each part is a hydraulic cylinder, can realize enclosure-type and connect combination between three.Second hydraulic cylinder plays the effect of the direction of transfer of conversion power, and last force direction is downward, assists in novel cutting ring entirety press-in soil.
Consult Fig. 9, the top of outer cutter hub 3 is connected with top cover 9 further, by pressing cover 9 by novel cutting ring press-in soil.Top cover 9 is provided with pulling part 91, and pulling part 91 for lifting novel cutting ring from soil.The center of top of top cover 9 is provided with level meter, the bubble such as surrounded by fiberglass, for as indicating the force direction that presses down or lift and horizontal plane.
Protection content of the present invention is not limited to above embodiment.Under the spirit and scope not deviating from inventive concept, the change that those skilled in the art can expect and advantage are all included in the present invention, and are protection domain with appending claims.
