Abstract
The utility model belongs to a soil sampling tool of engineering geological investigation, in particular to a soil sampler which is used in the soil sampling of engineering geological investigation. It mainly solves the problems that the soil sampler of the prior art has a complicated structure and a cockamamie operation, and the internal soil sampler has a poor international universal property and a high cost price. The main technique is characterized in that the soil sampler comprises a sampling barrel, a connector, a cylinder, a piston rod, a movable piston and a fixed piston. When the water pressure fixed soil sampler of the utility model is used, the movable piston which is installed in the cylinder does a relative movement on the sampling barrel with the fixed piston which is installed in the sampling barrel. The inner chamber of the sampling barrel is used for sampling. The utility model has the advantages of convenient sampling, good universal property, etc. It is especially applicable for the sampling of flow plastic soil, soft plastic clayey soil and partial soil and silt raw condition structure soil sample in the engineering investigation.
Description
The utility model belongs to a kind of engineering geologic investigation soil sampling instrument.Particularly a kind of soil sampler in engineering investigation soil property sampling usefulness.
Hydraulic pressure fixed piston soil sampler complex structure, Operation and Maintenance that prior art is used are all more loaded down with trivial details, can not adapt to the needs of China's engineering investigation.Though domestic existing hydraulic pressure is fixedly simplified in soil sampler structure, the operation more greatly, its diameter that fetches earth is poor with the length versatility that fetches earth, the needs of incompatibility engineering.In addition, many probe tubes made of copper of the structural requirement adapted of this soil sampler, cost height and application life are low, not competent far away engineering investigation requirements of one's work.
The purpose of this utility model is to design a kind of soil sampler, it can be solved takes in the engineering investigation boring that stream is moulded, softly moulded, the problem of cohesive soil and part silt, flour sand garden shape structure soil sample, improve its usability and economy, and on fetch earth diameter and length, can do any adjustment, use to be applicable under the different condition.
The purpose of this utility model is to realize like this, hydraulic pressure fixedly soil sampler is made up of connector, cylinder barrel, piston rod, moving piston, fixed piston and sampling tube, connector connects with cylinder barrel, moving piston end face contacts with the connector end face in cylinder barrel, moving piston connects with sampling tube, in the bottom of sampling tube fixed piston is housed, fixed piston center and piston rod are fixed, piston rod connects with connector by moving piston center hole, moving piston is in cylinder barrel, and piston rod constitutes slipper seal with moving piston center hole inwall and is connected.Inlet opening on the connector 1 communicates with the cavity that the inner wall of cylinder piston rod moves between piston 5 upper surfaces, and the weep hole on the connector communicates with plunger, and one way valve is housed on delivery port, is provided with refluxing opening in the bottom of piston rod.
Below in conjunction with accompanying drawing the utility model is described.
Accompanying drawing is the utility model structural representation.
Referring to accompanying drawing, when the utility model uses, with drilling rod with after connector 1 connects, put at the bottom of the thief hole, press water by water inlet 11 on the connector 1 in cylinder barrel 8, in the cavity between the upper surface of piston rod 6 and moving piston 5, promote moving piston 5, driving sampling tube 7 moves downward, because fixed piston 9 and piston rod 6, connector 1 forms and is fixedly connected, so just make piston 5, fixed piston 9 is done relatively near motion, and make sampling tube 6 stretch out cylinder barrel 8, under moving piston 5 effects, sampling tube 7 is pressed in the soil takes a sample, when moving piston 5 with after fixed piston 9 contacts, the water inlet 11 on the connector 1 is by going back to hole 10 on the piston rod 6, the cavity of piston rod 6 communicates with delivery port 2 on the connector 1, make the hurried decline of hydraulic pressure, and the demonstration sampleman is finished, for reducing sampling tube 7 because of getting rusty, be out of shape and influence sampling effect, replace copper probe tube, sampling tube 7 inwalls can be lined with plastic liner, and for increasing the hydraulic pressure utilization rate, moving piston 5 adopts slipper seal to be connected with cylinder barrel 8 with piston rod 6, moving piston 5 connects by bolt 4 with sampling tube 7, so that change conveniently, irritate for preventing that muddy water is counter, be provided with one way valve 3 in the weep hole 2 on connector 1.Emit water to judge whether sampling finishes, and sampling is mentioned the aluminium bar after finishing by hurried decline of slush pump gage or aperture on the observation ground during use, the taking-up soil sampler, the soil sampler that more renews is carrying out lower whorl sampling work, by operating with quadrat method.
The utlity model has easy and simple to handlely, soil sampling is effective, and versatility is better, and the advantage such as reduce cost can be widely used in and get in the engineering investigation that stream is moulded, soft plasticviscosity soil and part soil, flour sand original state structure worker level soil sample use.
