Background technology
Along with the develop rapidly of science and technology, civil engineering construction prospecting, in-situ test, and the scientific research level of the soil body is greatly improved, and become the main method of quantitative evaluation Rock And Soil engineering property.In order to the engineering characteristic enabling laboratory soil test result truly reflect the original state soil body, and soil body physical index and mechanical characteristic data test result are closer to the virgin state of the soil body, and the sampling quality improving undisturbed soil sample just seems particularly important.
Soil sample needed for soil test is generally taked by rig and corresponding soil sample barrel, is prepared into standard three axle sample after transporting testing laboratory back further.Make efficiency is lower, and cutting soil process causes certain disturbance to soil sample, have impact on the mechanical characteristic of soil sample, and natural moisture content, density etc. also can have a significant impact.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of revolution cutting type soil basketing method is provided.
Concrete steps are:
(1) set up a kind of revolution cutting type soil sample barrel, comprise pipe in soil sample barrel epimere, soil sample barrel hypomere outer tube, soil sample barrel hypomere.Soil sample barrel epimere is double-deck annular hollow circular-tube, outer shroud and inner ring are by connecting in ratchet shape, and establish miniature hydraulic pump in soil sample barrel epimere, hydraulic pump bottom is connected with hydraulic channel, and attached packoff, soil sample barrel epimere is connected by screw thread with soil sample barrel hypomere outer tube; In soil sample barrel hypomere outer tube and soil sample barrel hypomere, pipe adopts bushing formula, and soil sample barrel hypomere outer tube is the integral type pipe of band spiral groove, and groove coil angle of elevation is 30 °, is soil body output channel, has zigzag monocline blade bottom soil sample barrel hypomere; Guan Weisan sheet fit-type annulus in soil sample barrel hypomere, can be stretched internal diameter by hydraulic means; Soil sample barrel hypomere outer tube is connected by hydraulic connecting rod with shellring shape hydraulic channel, can exert pressure to pipe in three soil sample barrel hypomeres, and in soil sample barrel hypomere, there is spherical bearing pipe and hydraulic connecting rod junction;
(2) be installed on borer drill rod after installing the spiral fashion interface of step (one) described revolution cutting type soil sample barrel additional fastening structure, when creeping into, the monocline blade of soil sample barrel hypomere outer tube lower end cuts the soil body, the discarded soil body cut enters groove along monocline blade, then discharges gradually; Before mentioning borer drill rod, open hydraulic means and control power supply, hydraulic pump is started working, make to manage in soil sample barrel hypomere stressed by hydraulic channel, the internal diameter of pipe in soil sample barrel hypomere is impelled to diminish, make pipe in three soil sample barrel hypomeres fully wrap up and clamp soil sample, finally mention borer drill rod, namely complete taking of soil body sample.
Equipment therefor of the present invention is light-duty, little to sample disturbance, sample preparation success ratio is high, easy to use, efficient.
