Abstract
A kind ofly relate to geotechnique test,, a drawing out soil equipment that is connected on the transmission mechanism that can make its rotation and descend is simultaneously arranged particularly in order to the extracting soil instrument of soil body unit weight test.Cutting native cutting ring and can move simultaneously with transmission mechanism during work in the drawing out soil equipment enters " rotary-cut " in the soil layer.Place to cut and get the cutter cutting ring because the assembling effect between ring set and plane bearing only descends with transmission mechanism in the native cutting ring, directly incision is repaiied soil in the earth pillar that native cutting ring effect forms and is taken a sample by cutting.But this extracting soil instrument direct sample, soil sample removal are easy, easy to use, and the drawing out soil equipment that the has overcome prior art hammer of need choosing hits the soil sample error that sampling exists, and cutting ring rapid wear, sample rate wait defective slowly.
Description
The present invention relates to geotechnique's test, particularly in order to test the extracting soil instrument of soil body unit weight.
The soil sample of soil body unit weight test usefulness normally lies in a sleeve on the soil layer of evening out, and the personnel selection hammer hits to be squeezed into it in soil, has dug with spade and has filled native sleeve, the surplus soil at its two ends of equating and obtaining.During test, be with soil sample together with the sleeve check weighing, formula computational methods by measure again draw the physical quantity of soil sample.Operation and calculating is trouble comparatively, and because the artificial easy left and right sides of hammering cutter deflection, soil sample is compressed because of lateral resistance, make the unit weight of soil mass itself produce error because of disturbance, influence measuring accuracy, the cutting ring easy deformation is damaged during next hammering, and soil sample is destroyed when unloading sleeve simultaneously, thereby this drawing out soil equipment exists, and sampling is slow, cutting ring consumption is big, and the unwarrantable defective of quality of soil sample.
But the extracting soil instrument that the purpose of this invention is to provide a kind of direct sample, it can eliminate the soil sample error, and the cutting ring mounting or dismounting of fetching earth of dress soil sample are easy, easy to use, but continuous sampling.
Extracting soil instrument provided by the invention has the transmission mechanism of a rotatable and lifting simultaneously, and transmission mechanism is installed in the frame of extracting soil instrument, but and connects the drawing out soil equipment of a direct sample.This drawing out soil equipment is by cutting native cutting ring, the cutting ring that fetches earth, and composition such as cutterhead ring set, plane bearing, baffle plate.The upper end of cutting native cutting ring is cylindricality, there is one group of equally distributed helical angle cutter the lower end, its lead angle is 10～40 °, the lower end of helical angle cutter is welded with a blade, the blade face can be a plane, also curved surface, cutting native cutting ring directly is contained on the cutterhead, placing the cutting ring of cutting in the native cutting ring that fetches earth is that a dismountable opposite opened sleeve and mobile blade are formed, fetch earth the external diameter of cutting ring less than cutting 4～10 millimeters of native cutting ring blade place internal diameters, the cutting ring that fetches earth cooperates with the lower end of ring set on being fixed on cutterhead and links to each other, and can install and remove at any time.A plane bearing directly is inserted in protruding garden on the cutterhead, ring set is contained in the plane bearing place, with plane bearing one slight radial clearance is arranged, baffle ring in the ring set leans on mutually with plane bearing that is assembling and protruding garden, to control its axial distance, baffle plate is fixed on ring set on the protruding garden of cutterhead with connector.Whole drawing out soil equipment is connected with transmission mechanism by cutterhead.Transmission mechanism has a screw rod and associated nut, and the worm gear that is connected by key with screw rod and one are equipped with the worm engaging of runner (also hand lever, motor etc.), drive other driving members by rotating wheel and realize rotation and elevating movement.During work, cut the outer cutter of soil with screw rod rotation and decline, the gap effect of fetch earth cutting ring flat bush and ring set and plane bearing only descends and does not rotate.
The present invention has overcome the deficiency of prior art, drawing out soil equipment can directly enter the soil layer sampling, the speed that fetches earth is fast and easy and can not cause the unit weight error of soil sample itself because of soil disturbance, guarantee measuring accuracy, simultaneously because the cutting ring that fetches earth is a demountable structure, therefore, the removal soil sample is very easy, and can increase the turnover rate of cutting ring.After cutting ring drew off the soil sample weighing, it was heavy to deduct ring, brought convenience to calculating, can not have disturbance and intactly preserved directly obtaining or test soil sample behind the unit weight again simultaneously, used for mechanical test.
Accompanying drawing has been described one embodiment of the present of invention.
Fig. 1 is the overall construction drawing of extracting soil instrument.
Sectional drawing when Fig. 2 works for drawing out soil equipment.
Fig. 3 is the expanded view of cutting native cutting ring.
