Adopt the weight to hit that beat or the static pressure mode makes in undisturbed sample gets into the geotome, when lifting device fetches earth, landing under the expansion end cephalad, the lower extreme of elastic sleeve tightens up the internal diameter and diminishes, and the effectual soil sample that has prevented in the geotome comes off, has improved the complete degree of soil sample and the success rate of soil sampling.
Description
Technical field
The utility model relates to a kind of drawing out soil equipment for engineering exploration.
Background technology
In engineering investigation drilling process, when boring reach desired depth position need undisturbed soil sample at the bottom of extraction hole time, general employing drilling rod connects soil sampler, from hell by soil sampler at the bottom of hand-hole, weight impact or static pressure mode is adopted to make undisturbed soil sample enter in soil sampler, drilling rod in being holed by proposition and soil sampler, to ground, then take out soil sample in soil sampler.In sampling process, often can there is the phenomenon that soil sample comes off at the bottom of hole, cause key level undisturbed soil sample to lack, directly have influence on investigation result quality, operating efficiency and exploration cost.
Summary of the invention
The purpose of this utility model is the deficiency existed for prior art, provides a kind of drawing out soil equipment ensureing undisturbed soil sample difficult drop-off.
For achieving the above object, the technical scheme that the utility model drawing out soil equipment adopts is:
A kind of drawing out soil equipment, comprise the soil sampler of Connection Block and tubular, described soil sampler comprises inner core and urceolus, urceolus is socketed in the outside of inner core, and urceolus upper end is threaded with Connection Block, and the lower end of urceolus is provided with the movable end be slidably connected, inner core bottom is provided with resilient sleeve, the upper end of resilient sleeve is fixedly connected with the lower end of inner core, the lower end of resilient sleeve and movable end clamping, and the lower end of resilient sleeve is propped up and the medial surface of resilient sleeve is flushed with the medial surface of movable end by movable end.Weight impact or static pressure mode is adopted to make undisturbed soil sample enter in soil sampler, on when carrying drawing out soil equipment, the downward landing of movable end, the lower end of resilient sleeve is tightened up internal diameter and is diminished, effectively prevent the soil sample in soil sampler to come off, improve the integrity degree of soil sample and the success rate of soil sampling.
Described urceolus lower end is provided with screw thread, movable end is connected to the lower end of urceolus by thread bush, the inside of thread bush is provided with chute, and the upper end of movable end is provided with the bulge loop coordinated with chute, and the upside of bulge loop is provided with the back-up ring for propping up resilient sleeve lower end.Connect movable end and urceolus by thread bush, assembly structure is simple, and is convenient to assembling.
The outer peripheral face of inner core upper end has been arranged symmetrically with anti-rotation projection, and the inner peripheral surface of urceolus upper end offers the groove coordinated with anti-rotation projection.Prevent inner cylinder rotating, improve the integrity degree of soil sample.
Described inner core is transparent inner core, is axially provided with scale.Can be visually observed the structure of soil sample by transparent inner core, be convenient to retention of taking pictures, scale can better embody each the thickness of the layer, and when retaining photo, information more comprehensively.
The utility model compared with prior art, has the following advantages:
When soil sample enter carry drawing out soil equipment on after soil sampler time, downward landing under the effect of movable end suction and hole wall frictional force at the bottom of hole, the lower end of resilient sleeve does not support and tightens up, internal diameter diminishes, soil sample is got lodged in inner core, effectively prevent soil sample to come off, improve the integrity degree of soil sample and the success rate of soil sampling.
This drawing out soil equipment, for engineering investigation original state soil layer sampling instrument, have that structure is simple, low cost of manufacture, easy to operate, undisturbed soil taking rate advantages of higher, be applicable to weight impact or static pressure mode sample, be adapted at soft moulding in ~ hard plastic cohesive soil, loose ~ closely knit grittiness soil layer and get undisturbed soil sample.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of drawing out soil equipment, comprise the soil sampler 2 of Connection Block 1 and tubular, soil sampler 2 comprises inner core 3 and urceolus 4, urceolus 4 is socketed in the outside of inner core 3, urceolus 4 upper end is threaded with Connection Block 1, urceolus 4 lower end is provided with screw thread, movable end 6 is connected by thread bush 5, the inside of thread bush 5 is provided with chute 7, the upper end of movable end 6 is provided with the bulge loop 8 coordinated with chute 7, inner core 3 lower end is connected with resilient sleeve 9, the upper end of resilient sleeve 9 is fixedly connected with the lower end of inner core 3, the lower end of resilient sleeve 9 and movable end 6 clamping, the upper end of movable end bulge loop is provided with the back-up ring 10 for propping up resilient sleeve lower end, the lower end of resilient sleeve is propped up and the medial surface of resilient sleeve is flushed with the medial surface of movable end by back-up ring 10.The outer peripheral face of inner core 3 upper end has been arranged symmetrically with anti-rotation projection 11, the inner peripheral surface of urceolus upper end offers the groove 12 coordinated with anti-rotation projection, anti-rotation projection 11 is plugged in groove 12, prevent inner cylinder rotating, inner core adopts transparent inner core, is axially provided with scale, the structure of soil sample can be observed visually by transparent inner core, be convenient to retention of taking pictures, scale can better embody each the thickness of the layer, retains the information of photo more comprehensively.Resilient sleeve adopts rubber sleeve.
As shown in Figure 4 and Figure 5, when fetching earth, the power that fetches earth drives soil sampler to enter stratum by drilling rod, and soil sample enters the inner core of soil sampler, when the degree of depth that fetches earth reaches precalculated position, on carry drilling rod in hole and drive the soil sampler at the bottom of hole to promote together to portal simultaneously, when upper carrying, under movable end 6 suction and the effect of hole wall frictional force at the bottom of hole and slide downward, back-up ring and resilient sleeve 9 depart from, the lower end of resilient sleeve 9 is tightened up internal diameter and is diminished, and soil sample is remained in inner core, ensure that integrality and the authenticity of soil sample.After drawing out soil equipment portals, inner core is taken out the structure and each the thickness of the layer of directly observing soil sample, retention of taking pictures.
