Abstract
The utility model belongs to a soil sampling tool of engineering geological investigation, in particular to a soil sampling device of engineering geological investigation, which solves the problems that the soil sample is unable to be sampled and the sampling quality is low because the opening port of the soil sampling device of fixed type is unable to form vacuum. The main technique is characterized in that a connector and a sampling tube are connected in a piston type connection. After the sampling, the connector forms vacuum for the sampled soil sample in the sampling tube through a piston connecting rod, which prevents the soil sample from shedding and guarantees the quality of the soil sample. The utility model has the advantages of convenient sampling and high quality. It is a safe and reliable soil sampling device with a simple structure. And it can be widely used in the soil sampling of geologic investigation.
Description
The utility model belongs to engineering geologic investigation soil sampling instrument, particularly a kind of soil sampler that is used for engineering geologic investigation soil property sampling usefulness.
In geological mapping, very important element task in the collection of undisturbed soil sample, but the instrument of sampling level of China and use and operation thereof are all relatively backward at present, and it is very lack of standardization, the heavy wall soil sampler that prior art is generally used, the size disunity, owing to adopt opened type, can not form vacuum and not have suction, stream is moulded, the soft soil of moulding pours off in the soil sampler and gets so cause, and tough cohesive soil dials and constantly also gets to come up, and prior art also can be out of shape owing to bushing pipe, cause influence quality of soil sample such as get rusty.
The purpose of this utility model is, design a kind ofly to utilize the pull of vacuum effect from boring, with stream mould, the soft novel soil sampler of taking a sample of moulding with tough cohesive soil.
The purpose of this utility model is to realize like this, soil sampler is by connector, piston rod, sealing mat, cylinder sleeve and probe tube are formed, connector is connected with piston rod one end, and the piston rod other end is located in the cylinder sleeve, and cooperates with cylinder sleeve bore by the sealing mat on the piston rod, cylinder sleeve top is provided with steam vent, the cylinder sleeve bottom is connected with probe tube, and the probe tube front end is provided with sharp keen cutting edge, is provided with bushing pipe in the probe tube.
Below in conjunction with accompanying drawing the utility model is described.
Accompanying drawing is the utility model structural representation.
Referring to accompanying drawing, during use soil sampler upper binding head 1 is connected with drilling rod, and put at the bottom of the hole, at this moment drilling rod presses down connector 1, probe tube 6 is pressed in the soil sample, because connector 1 contacts with probe tube 6, make sealing mat 4 leave the mating holes of cylinder sleeve 3, the inner chamber of probe tube 6 communicates with steam vent 5 on the connector 1, the air of probe tube 6 inner chambers can be discharged from steam vent 5, after probe tube 6 is pressed into the soil sample prescribed depth, lift connector 1 by drilling rod, piston rod 2 drives sealing mat 4, in cylinder sleeve 3, form sealing, piston rod 2 moves upward, the soil sample of probe tube 6 inner chambers and taking-up forms vacuum, soil sample jail guest is inhaled in the inner chamber of probe tube 6, and do not come off, with soil sampler ground is proposed, easily be pressed in the soil in order to make probe tube 6, be provided with sharp keen cutting edge at probe tube 6 front ends, for the distortion that reduces probe tube 6 and get rusty and wait the influence effect of taking a sample, in probe tube 6, be provided with removable liner 7, bushing pipe 7 can adopt antirust bushing pipes such as plastics, for probe tube 6 is changed to convenient, probe tube 6 adopts changeable type to connect with connector 3.
The utlity model has easy to usely, pull of vacuum is big during soil sampling, and cost is low, effective, the sampling quality advantages of higher can be widely used in and get in the geological mapping that stream is moulded, soft mould and tough clay sampling is used, a kind of comparatively desirable convenient, simple soil sampler.
Claims (2)
1, a kind of soil sampler is made up of connector, piston rod, sealing mat, cylinder sleeve and probe tube, it is characterized in that:
