Description
Technical field
The present invention relates to geotechnical engineering investigation technical field, more specifically to a kind of ground prepressing device and
Its application method.
Background technology
Soil classifiction be the soil body in the presence of load, with resistance failure by shear ability.The shearing resistance of soil
Intensity is calculating the bearing capacity of foundation soil as an important mechanical property of soil, evaluates the bearing capacity of ground
And stability, the anti-of soil is required for during the soil stress of the stability and soil-retaining structure of calculating foundation ditch and natural side slope
Cut intensity index.Soil classifiction mainly passes through direct shearing and triaxial shear test side in testing indoors
Method is measured.Usual indoor direct shear test uses consolidated quick shear method, in order to recover the natural strain condition of soil, needs
Preconsolidation is carried out to soil sample before the test.Stability under loading is pre- soil sample when the refinement and soil sample precompressed of loading load
Press the key technology of consolidation.But the existing prepressing device general structure for using is complex, in-convenience in use,
It is difficult to accurate control.
It is those skilled in that art urgently to be resolved hurrily therefore, because there is above-mentioned technological deficiency in the prior art
Technical problem.
The content of the invention
The purpose of the present invention is a kind of ground prepressing device of offer and its application method, it is intended to solved in the prior art
The prepressing device of presence is complicated, the problem of inconvenient operation.
To achieve the above object, the present invention provides following technical scheme:
A kind of ground prepressing device, including base, retainer ring, precompressed bucket, connecting rod and prepressing device, it is described
Base is provided with prepressing device, and the base of the prepressing device both sides is provided with connecting rod, the connecting rod
Upper end is connected ring, and the retainer ring middle part is provided with precompressed bucket, the precompressed bucket both ends open, the fixation
Ring is symmetrically arranged on two with base, connecting rod and prepressing device, and the prepressing device includes retractor device and pressing plate,
The pressing plate diameter is identical with precompressed bucket internal diameter.
A kind of application method of ground prepressing device, it is characterised in that:Comprise the following steps:
1) prepressing device of side is stretched downwards, pressing plate is stretched out from precompressed bucket;
2) soil sample to be studied is laid in precompressed bucket, extend into the pressing plate on the prepressing device of opposite side pre-
In pressure bucket, start precompressed;
3) after the completion of precompressed, the prepressing device of side is stretched downwards, pressing plate is stretched out from precompressed bucket,
The prepressing device of opposite side continues to compress, and the soil sample for completing precompressed is ejected.
The present invention is advantageous in that:By in precompressed bucket both sides, symmetrical prepressing device is set such that it is able to
Two-way precompressed is carried out to soil sample in precompressed bucket, precompressed speed is improve, and it is easy to operate.Structure letter of the present invention
Single, easy to use, operation is easy, and pre-compressed effect is good.
