The utility model discloses when carrying out sea area deep hole exploration, can directly take undisturbed sample, and easy clear hole, the soil sample disturbance that gains is less, quality class is high.
Description
Technical field
The utility model relates to the device that a kind of engineering geological drilling takes undisturbed sample, particularly relates to the uncovered thin-wall sampler of a kind of drilling type.
Background technology
In engineering geologic investigation, be the physico-mechanical properties under the native state of understanding sub-surface, usually need to take its undisturbed sample to carry out correlation test analysis.Soil sampler is the special implement taking undisturbed soil sample in the borehole.
According to the undisturbed soil sampler standard that " Code for investigation of geotechnical engineering " GB50021-2001 (version in 2009) specifies, can be divided into thin-walled and heavy wall two class by wall thickness, the mode pressing in underground layer can be divided into injection and revolution two classes.Thin-wall sampler can be divided into the types such as opened type, fixed piston formula, hydraulic pressure fixed piston formula, free-piston type by form of structure.Rotary type soil sampler has two kinds: single action triple (double) pipe soil sampler and two dynamic triple (double) pipe soil sampler.
At present, China's great majority are reconnoitred unit and are used opened type thin-wall sampler, and this is the simplest thin-wall sampler of one, compared with other types thin-wall sampler, have advantage simple to operate.Opened type thin-wall sampler has good application in the exploration of land, but when carrying out marine site deep hole exploration, because in boring, sediment is thicker, and clear hole difficulty, this kind of soil sampler directly cannot take undisturbed soil sample, and because roach room is too short etc., reason also cannot take undisturbed soil sample to other types soil sampler.
At present, in Practical Project, deep hole sampling in marine site is generally all taked in core barrel, adopt that the soil sample disturbance that obtains in this way is comparatively large, credit rating is low, cannot relevant Experimental Study On Mechanical Properties be carried out according to " Code for investigation of geotechnical engineering " GB50021-2001 (version in 2009) regulation.
Utility model content
In order to solve the shortcoming of prior art, the utility model provides a kind of drilling type uncovered thin-wall sampler, and this soil sampler when carrying out marine site deep hole exploration, directly can take undisturbed soil sample, and easy clear hole; Be specially adapted to the thicker and situation of clear hole difficulty of marine site deep drilling sediment.
For achieving the above object, the utility model is by the following technical solutions:
The uncovered thin-wall sampler of a kind of drilling type, comprise light-wall pipe, the upper end of described light-wall pipe is provided with the tool joint be connected with drilling rod, and the upper end of described light-wall pipe inside is provided with ball valve, and described ball valve place is provided with steel ball, and described light-wall pipe inside is provided with roach room; Described light-wall pipe lower end is connected with fetching earth to manage, and described light-wall pipe manage detachably with fetching earth; Described pipe lower end of fetching earth is connected with drill bit, described in fetch earth in pipe and be provided with soil sample lining bucket.
The described pipe that fetches earth is connected with roach room and drill bit respectively by screw thread two ends.
Described tool joint is latching connector.
It is box-like that a side of the described pipe that fetches earth is set to snap close half.
The described pipe that fetches earth is connected with drill bit by drill-bit type cutting edge, and described drill-bit type cutting edge place is provided with alloying pellet.
According to marine site probing sediment thickness, the length of described roach room is set to 1 meter.
The beneficial effects of the utility model are:
(1) this soil sampler of the present utility model can carry out marine site deep hole exploration and fetches earth, and directly can take undisturbed soil sample;
(2) light-wall pipe lower end of the present utility model is connected with fetching earth to manage, and light-wall pipe manage detachably with fetching earth, and when this structure makes to carry out marine site deep hole exploration, clear hole is more convenient.
Accompanying drawing explanation
Fig. 1 is the uncovered thin-wall sampler structural representation of drilling type of the present utility model.
Wherein, 1, tool joint; 2, steel ball; 3, light-wall pipe; 4, roach room; 5, fetch earth pipe; 6, soil sample lining bucket; 7, drill bit.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is described further:
As shown in Figure 1, the uncovered thin-wall sampler of a kind of drilling type, comprises light-wall pipe 3, the upper end of described light-wall pipe 3 is provided with the tool joint 1 be connected with drilling rod, the upper end of described light-wall pipe 3 inside is provided with ball valve, and described ball valve place is provided with steel ball 2, and described light-wall pipe 3 inside is provided with roach room 4; Described light-wall pipe 3 lower end is connected with the pipe 5 that fetches earth, and described light-wall pipe 3 is detachable with the pipe 5 that fetches earth; Described pipe 5 lower end of fetching earth is connected with drill bit 7, described in fetch earth in pipe 5 and be provided with soil sample lining bucket 6.
The described pipe 5 that fetches earth is connected with roach room 4 and drill bit 7 respectively by screw thread two ends.
Described tool joint 1 is latching connector.
It is box-like that a side of the described pipe 5 that fetches earth is set to snap close half.
The described pipe 5 that fetches earth is connected with drill bit 7 by drill-bit type cutting edge, described drill-bit type cutting edge place is provided with alloying pellet, the connection of this structural strengthening between drill-bit type cutting edge and drill bit 7.
According to marine site probing sediment thickness, the length of described roach room is set to 1 meter.
Operating principle of the present utility model is:
First steel ball 2 is taken out before sampling, then soil sampler 5 is lowered at the bottom of hole, sediment thickness is estimated with a upper round trip hole depth difference by measuring, then creeping into downwards to estimating original state soil layer, using static pressure method or the few striking injection soil layer of weight immediately instead, after reaching regulation depth of penetration, steel ball 2 being entered soil sampler 5 under drilling rod hollow pipeline, then promote and pull off boots subsoil, also rotatablely twist off boots subsoil, finally unload probe tube 5, two ends add a cover and seal up adhesive tape, sampling of having waxed.
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
