Description

A kind of novel soil sampler
Technical field
The present invention relates to exploring equipment technical fields, and in particular to a kind of novel soil sampler.
Background technique
In engineer geological prospecting and survey, in order to acquire the physical and mechanical property indexs of foundation soil, need that soil will be taken The certain depth of device insertion ground takes out undisturbed soil sample and is analyzed, to obtain the three-phase state parameter of soil, in turn Reference is provided for the calculating of pile foundation.Due to the shortage of urban land, the building height of building is also increased, this is also to ground Bearing capacity proposes high requirement, therefore builds and reconnoitre each of the foundation soil layer as a particularly important ring, provided Kind physical parameter is most important for the stability of building.
When soil investigation, soil exploration, need to drill using auger to certain depth to visit and the soil physics under the depth is taken to join Number, disturbs caused by the soil lifts of ground reaction force extruded hole bottom, prospecting personnel generally will use mud branch in order to prevent Support drilling.After slurry prime, soil sampler is inserted by prospecting personnel to drill and stretches to designated depth to sample.However it is existing For some soil samplers during protruding into mud duct, mud, which easily pours into soil sampler, causes sampling soil mutually to be mixed with mud With, cause sample soil be difficult to reflect true soil information;Existing sampler structure is complicated simultaneously, during taking soil, takes Mud in earthenware, which is difficult to the place's of being extruded extractor, makes sampling soil take out drilling by soil sampler under the action of negative pressure.
Summary of the invention
The present invention to solve the above-mentioned problems, devises a kind of novel soil sampler, the structure of the soil sampler is simple, in mud Drilling hole bottom, which takes to facilitate when soil, will flow into the extrusion soil sampler of the mud in soil sampler, prevent from sampling native failure;This takes soil simultaneously Device vacuum effect is more preferable, can prevent sampling soil return mention during be scattered and cause sampling fail, and sample soil be easier from It is taken out in soil sampler, improves soil extracting efficiency.
In order to achieve the above technical purposes, reach above-mentioned technical effect, the present invention is achieved by the following technical solutions:
A kind of novel soil sampler, which is characterized in that be made of cutting ring, probe tube, end cap and connector, cutting ring is fixed on sampling The bottom of pipe, end cap are plugged in the top of probe tube, and connector is fixed on the top of end cap;The cutting ring is plugged in probe tube Bottom, probe tube are made of two semicircle sections of jurisdiction, and end cap is inserted into the lumen of probe tube and is connected by fixing screws, end cap Bottom center at be provided with cylindrical limiting groove, end cover surface is provided with the gas vent with limiting groove perforation, the top of end cap It is provided with connector slot, connector is embedded in connector slot, and through-hole, through-hole of the piston rod through connector are provided on the central axes of connector and end cap It is inserted into cutting ring, the bottom of piston rod is fixed with piston, and piston bottom surface is concordant with the bottom surface of cutting ring, and the top surface of piston is equipped with Retention bead, the outer diameter of retention bead and the internal diameter of limiting groove are equal.
Preferably, the quantity of the gas vent is not less than 2 and not 2 integer portion, and gas vent symmetrically opens up and end cap Transition face on.
Preferably, the cutting ring is threadedly coupled with probe tube, and the basil inclined-plane of cutting ring and the angle of horizontal plane be 45 °~ 60°。
Preferably, the piston is rubber piston.
The beneficial effects of the present invention are: the structure of the soil sampler is simple, can facilitate when mud drilling hole bottom takes soil will flow The mud entered in soil sampler squeezes out soil sampler, prevents from sampling native failure;The soil sampler vacuum effect is more preferable simultaneously, can prevent from sampling Soil is scattered during returning and mentioning and sampling is caused to fail, and samples soil and be easier to take out from soil sampler, improves soil extracting efficiency.
Detailed description of the invention
In order to illustrate the technical solution of the embodiments of the present invention more clearly, will be described below to embodiment required Attached drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, for ability For the those of ordinary skill of domain, without creative efforts, it can also be obtained according to these attached drawings other attached Figure.
Fig. 1 is the external structure schematic diagram of novel soil sampler;
Fig. 2 is the schematic diagram of the section structure of novel soil sampler.
In attached drawing, parts list represented by the reference numerals are as follows:
1- cutting ring, 2- probe tube, 3- end cap, 4- connector, 5- piston rod, 11- piston, 12- retention bead, the fixed spiral shell of 21- Nail, 31- gas vent, 32- limiting groove.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts all other Embodiment shall fall within the protection scope of the present invention.
Refering to fig. 1 shown in -2, a kind of novel soil sampler is made of cutting ring 1, probe tube 2, end cap 3 and connector 4, and cutting ring 1 is solid Due to the bottom of probe tube 2, end cap 3 is plugged in the top of probe tube 2, and connector 4 is fixed on the top of end cap 3;The cutting ring 1 It is plugged in the bottom of probe tube 2, probe tube 2 is made of two semicircle sections of jurisdiction, and end cap 3 is inserted into the lumen of probe tube 2 and leads to The connection of fixing screws 21 is crossed, cylindrical limiting groove 32 is provided at the bottom center of end cap 3,3 surface of end cap is provided with recessed with limit The gas vent 31 of slot perforation, the top of end cap 3 are provided with connector slot, and connector 4 is embedded in connector slot, the central axes of connector 4 and end cap 3 On be provided with through-hole, piston rod 5 is inserted into cutting ring 1 through the through-hole of connector, and the bottom of piston rod 5 is fixed with piston 11, piston 11 bottom surfaces are concordant with the bottom surface of cutting ring 1, and the top surface of piston 11 is equipped with retention bead 12, and the outer diameter of retention bead 12 and limit are recessed The internal diameter of slot 32 is equal.
