Abstract

The utility model is related to a kind of improved beam section formula cutting ring soil sampler, is the improvement on the basis of conventional beam section formula cutting ring soil sampler, and its improvement is:Cutter head (7) is hollow circular cylinder, and hollow circuit cylinder leading portion knife-edge part is distributed sawtooth using quartering vertical spin;The circular sleeve is that two identical hemizygous pipes (4) are connected the circular sleeve closed up by hinge (5), and it is fixed that openend passes through buckle (6).Other parts of the utility model and connected mode are with conventional beam section formula cutting ring soil sampler.Parts are improved to prepare by successful methods using commercially available material.The characteristics of soil sampler is:Simple in construction, with low cost, small to undisturbed soil disturbance, simple to operate, usability is strong, and shearing force is small.When sending laboratory back to and opening sample, it is only necessary to turn on lower bottom cover, buckle (6) is opened, soil sample in round buss just can be easily removed, greatly reduce the disturbance to original-state soil when fetching earth and opening sample.Preferably overcome the deficiency of existing apparatus.

Description

A kind of improved beam section formula cutting ring soil sampler
Technical field
The utility model is related to a kind of improved beam section formula cutting ring soil sampler, belongs to geotechnical engineering investigation technical field.
Background technology
Undisturbed soil sampling is a basic work in engineering geological investigation, environmental project, agriculture project, Hydraulic and Hydro-Power Engineering Make.Undisturbed soil refers to physical property, the mechanical property that the natural structure of style, i.e. soil sample should be kept during soil sample is taken Matter, chemical property etc. keep constant soil sample in sampling process.If the natural structure of sample is destroyed, just it is referred to as " disturbance sample ".The disturbance of soil sample is to be impermissible for or should try one's best in some engineering geologic investigations, the medium many fields of experimental study Avoid.
Cutting ring is the soil physical properties such as a kind of measurement characteristic curve of soil moisture, the soil weight, soil volumetric water content Index and the common tool for drilling through original-state soil.Conventional original state sampling method has core cutter method and In situ metal tube method.Core cutter method takes Soil needs first to excavate section hole, exists that complex operation, labor intensity is big, the low shortcoming of soil extracting efficiency;Beam section formula cutting ring sample Although tiretube process can once obtain the soil sample of multiple soil layers, soil extracting efficiency is higher, there is soil sample and releases difficult, soil sample point It is low from precision, the shortcomings of error is big.
Include eight cutting rings in conventional beam section formula cutting ring sleeve, sampling finish send back to laboratory carry out open sample when, hold very much Easily cause Secondary Disturbance.When particularly soil property is aleuritic texture soil, cutting ring is extremely difficult to be taken out.Therefore, deposited for current soil basketing method The problem of, to soil sampler work whole process carefully analyze, analysis fetch earth, cut soil, sample, open sample etc. each link It is middle to there is which disturbance, disturbance how is reduced to greatest extent, and the original state for keeping soil sample is most critical.
The content of the invention
The purpose of this utility model is the deficiency for overcoming prior art, and provide it is a kind of simple in construction, easy to operate and Laborsaving, soil sample original state degree is high, soil sample disturbs small beam section formula cutting ring soil sampler.
The utility model is the improvement on the basis of conventional beam section formula cutting ring soil sampler, and its improvement is:
A. it is built-in with the circular sleeves of eight cutting rings by two radiuses are identical, two ends are provided with externally threaded hemizygous pipe (4) it is connected by hinge (5) and closes up composition, openend is fixed by the buckle (6) being arranged in hemizygous pipe (4);In circular sleeve Footpath matches with the external footpath of cutting ring, and circular sleeve is connected with perforate base (3) and cutter head (7) respectively by the external screw thread at two ends;
B. cutter head (7) is hollow circular cylinder, and hollow circuit cylinder leading portion knife-edge part is distributed sawtooth, saw using quartering vertical spin Tooth is by root heavy wall to top thin-walled into blade-like;Cutter head (7) internal diameter is identical with footpath in cutting ring body, the rear end inwall of cutter head (7) Provided with internal thread, cutter head (7) is connected by the internal thread with circular sleeve.
Other parts of the utility model and connected mode are with conventional beam section formula cutting ring soil sampler.Improve parts and use city Material is sold to prepare by successful methods.
Technology character and superiority of the present utility model is:
1st, this soil sampler is when earth is fetched earth in spy, and shearing force is small;When sending laboratory back to and opening sample, it is only necessary to turn on lower bottom cover, beat Buckle is opened, soil sample in round buss just can be easily removed;Greatly reduce the disturbance to original-state soil when fetching earth and opening sample.
2nd, overall material selection stainless steel, light, not upper to become rusty, to reduce friction when boring soil.
3rd, the sampler structure is simple, with low cost, disturbs small, easy to operate, the features such as usability is strong to undisturbed soil, very The good deficiency for overcoming existing apparatus.
Brief description of the drawings
Fig. 1 is soil sampler overall structure diagram of the present utility model.
Fig. 2 is circular sleeve structural representation of the present utility model.
Fig. 3 is the structural representation of the utility model cutter head (7).
Embodiment
This utility model is described in further detail below in conjunction with the accompanying drawings:
As shown in drawings, beam section formula cutting ring soil sampler of the present utility model is on the basis of conventional beam section formula cutting ring soil sampler Improvement, including connected handle 1, drilling rod 2, perforate base 3, hemizygous pipe 4, hinge 5, buckle 6 and cutter head 7.Wherein:
A. it is built-in with the circular sleeves of eight cutting rings by two radiuses are identical, two ends are provided with externally threaded hemizygous pipe 4 It is connected by hinge 5 and closes up composition, openend is fixed by the buckle 6 being arranged in hemizygous pipe 4;Circular sleeve internal diameter and cutting ring body External diameter matches, and circular sleeve is connected with perforate base 3 and cutter head 7 respectively by the external screw thread at two ends;
B. cutter head 7 is hollow circular cylinder, and hollow circuit cylinder leading portion knife-edge part is distributed sawtooth, sawtooth using quartering vertical spin By root heavy wall to top thin-walled into blade-like;The internal diameter of cutter head 7 is identical with footpath in cutting ring body, and the rear end inwall of cutter head 7 is provided with interior Screw thread, cutter head 7 is connected by the internal thread with circular sleeve.
Other parts of the utility model and connected mode are with conventional beam section formula cutting ring soil sampler.Improve parts and use city Material is sold to prepare by successful methods.The utility model is assembled as shown in accompanying drawing and finished.
When using:Hold with a firm grip handle 1, soil sampler is inserted in soil, when (allowing soil sample and base cover as far as possible full of soil sample in sleeve pipe Between leave space) when, take out soil sampler, slowly back out base 3 and cutter head 7, install casing cover, laboratory can be transported back; Casing cover is slowly turned on when opening sample, the buckle 6 in hemizygous pipe 4 is opened, intact undisturbed cutting ring soil sample is obtained.
It is actually used to show:The soil sampler is not only simple in structure, with low cost, and small to undisturbed soil disturbance, easy to operate, Usability is strong;And preferably overcome the deficiency of existing apparatus.
