Abstract

The present invention discloses one kind and depth loudspeaker reaming strength test can pop one's head in entirely, including fixture, expansion board, spring tab, rigid rod, hinged, snap ring and tool joint, the fixture is connected directly with rigid rod, rigid rod is connected with drilling rod, it is fixed above rigid rod with tool joint lap-joint using snap ring, tool joint, using being articulated and connected, 5 coil spring lugs is evenly arranged on the inside of expansion board with expansion board.Probe of the invention can promote opening, and when probe is promoted, expansion board drawing is cut improves test accuracy and benefit with lateral compression soil stone body, completion different depth in-situ mechanical parameter testing.

Description

One kind can pop one's head in depth loudspeaker reaming strength test entirely
Technical field
The present invention relates to a kind of test probes, are specifically that one kind can pop one's head in depth loudspeaker reaming strength test entirely.
Background technology
Pre- drilling type side pressure method of testing is common in-situ testing technique in engineering investigation, other depressor is placed on pre-drilled A certain predetermined depth, then pressurizes in drilling, and other depressor lateral expansion is made to compress hole wall Rock And Soil, measures hole wall Rock And Soil The relation curve of stress and volume change, so as to which all multi objectives such as foundation bearing capacity are obtained.
The other pressure instrument that in-situ test uses is advance drilling, and hole wall soil is unavoidably made to be subject to different degrees of disturbance, And test depth is limited to a certain extent.In addition, in pressing test process on side, the in-situ soil of a certain depth can only obtain Body parameter can not obtain the real-time mechanics parameter information along hole depth direction.
For pre- drilling type side pressure method of testing more than solving the disadvantage that, present invention probe can promote openings, when probe promotion, Expansion board drawing cut with lateral compression soil stone body, complete different depth in-situ mechanical parameter testing, so as to improve test accuracy and Benefit.
The content of the invention
It is an object of the invention to provide one kind depth loudspeaker reaming strength test to pop one's head in entirely, to solve above-mentioned background skill The problem of being proposed in art.
To achieve the above object, the present invention provides following technical solution:
One kind can pop one's head in depth loudspeaker reaming strength test entirely, including fixture, expansion board, spring tab, rigid rod, hinge Connect, snap ring and tool joint, the fixture are connected directly with rigid rod, rigid rod is connected with drilling rod, with boring above rigid rod Knock-off joint lap-joint is fixed using snap ring, and tool joint, using being articulated and connected, 5 circles is evenly arranged on the inside of expansion board with expansion board Spring tab.
Further scheme as the present invention:Use is threadedly coupled between the tool joint and drilling rod.
Further scheme as the present invention:The thickness of the spring tab is 5~10 millimeters.
Compared with prior art, the beneficial effects of the invention are as follows:Present invention probe can promote opening, when probe is promoted, Expansion board drawing is cut improves test accuracy and benefit with lateral compression soil stone body, completion different depth in-situ mechanical parameter testing.
Description of the drawings
Fig. 1 is the structure chart of the present invention.
In Fig. 1:1st, fixture, 2, expansion board, 3, spring tab, 4, rigid rod, 5, hinged, 6, snap ring, 7, tool joint.
Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work Embodiment belongs to the scope of protection of the invention.
Referring to Fig. 1, one kind can full depth loudspeaker reaming strength test pop one's head in, including fixture, expansion board, spring tab, Rigid rod, hinged, snap ring and tool joint, the fixture are connected directly with rigid rod, and rigid rod is connected with drilling rod, rigid rod Top is fixed with tool joint lap-joint using snap ring, and tool joint is with expansion board using being articulated and connected, and expansion board inside is uniformly It is provided with 5 coil spring lugs.
Use is threadedly coupled between tool joint and drilling rod.The thickness of spring tab is 5~10 millimeters.
The present invention operation principle be:The first step:Drilling machine completes round hole, and depth is determined according to test;
Second step:Using reaming bit in test position reaming, and form test plane;
3rd step:Drill is replaced into test probe, and by test probe in place to test position therefore;
4th step:Rigid rod and fixture are lifted, fixture squeezes spring tab expansion board and opens
5th step:Drilling rod, ground test instrument record lifting force and displacement data are promoted, and then calculates intensive parameter;
6th step:Rigid rod and fixture are transferred, expansion board is withdrawn, and carries on other test position intensive parameters.
