The structures such as tunnel, side slope are built in rock mass more, and are present in the structural planes such as the joint in rock mass, are rock mass knots
Part the weakest, the intensity of structural plane largely determine the intensity of rock mass in structure.In natural joint, filling
The presence of object be it is commonplace, thickness range is substantially from several millimeters to tens of milliseconds.For the rock mass at the joint containing filling, remove
Outside filler nature, mechanics effect is mainly by the control of packing density.Under natural strain condition, tunnel, side slope
Equal rock mass structural damage is mostly the failure by shear along joint plane.Therefore, the shearing mechanical property for filling joint is rock mass engineering project
The key problem of stability has highly important engineering significance and learning value.
However, frequently encountering some specific questions when carrying out filling joint shearing test in laboratory.Such as: into
When the irregular Rock Joint Plane shearing test of row outer profile, upper and lower joint plane need to be poured respectively to the cement bonded sand in regular shape
It starches in test block, carries out corresponding charges test again after conserving molding.At this point, how to guarantee with group joint opening width it is identical, and
Joint upper and lower surface does not misplace, and will be the premise and basis for testing win or lose.
It is adjusted in conclusion the utility model researching and designing is a kind of for the limit of Rock Joint Plane charges shear test blocks
New equipment.
Summary of the invention
It is filled in view of the shortcomings of the prior art, the utility model aims to provide one kind for Rock Joint Plane
Fill out the new equipment that the limit of object shear test block is adjusted, it is identical to be able to maintain joint opening width, and two surface of joint do not occur dislocation and
Carry out different joint charges tests；Keeping two surface of joint not occur, dislocation, charges are constant and carry out different opening width examinations
It tests.
To achieve the goals above, the utility model is achieved through the following technical solutions: a kind of be used for rock section
The new equipment that charges shear test block limit in reason face is adjusted, including support frame, adjusting crane, adjusting bolt, the fixed spiral shell of limit
Bolt, support frame and adjusting crane are steel structure, and the support frame is made of support plate, supporting leg and support leg, edge
Distance is slightly larger than test block width between two supporting leg of test block width direction, and the adjusting crane is by lifter plate, lifting leg, liter
Foot composition is dropped, is opened up on the lifter plate there are five bolt hole is adjusted, one of them is located at the geometric center of lifter plate, in addition
On four symmetrical separation diagonal lines；It adjusts on bolt hole equipped with adjusting bolt；Two lifting legs are along test block width direction distance and two
Supporting leg is along test block width direction apart from identical；Four limit fixed bolt holes are set on every lifting leg, limit fixing bolt
Equipped with limit fixing bolt on hole；It is respectively provided with a lifting foot on every lifting leg, to realize the lifting of upper joint test specimen；Institute
The support frame stated adjusts the setting of crane nesting, and the lower section for adjusting crane is arranged in support frame.
Lift adjustment joint opening width range is by support leg length and adjusts bolt length co-determination, therefore supporting leg is long
Degree and adjusting bolt length need to determine by testing.
The utility model has the following beneficial effects:
1, the function of adjusting joint opening width and two surface of joint is made not misplace can be achieved.
2, apparatus structure is simple and novel, convenient to use.
3, durable, it can be recycled, save the cost.

Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
Referring to Fig.1-7, present embodiment uses following technical scheme: one kind is sheared for Rock Joint Plane charges
The new equipment that test specimen limit is adjusted is made of support frame, adjusting crane, adjusting bolt 7, limit fixing bolt 8, to guarantee dress
Overall stability and rigidity are set, two main bracing frame of device, adjusting crane are made of steel, and the support frame is by supporting
Plate 1, supporting leg 2 and support leg 3 are constituted, and distance is slightly larger than test block width between two supporting leg 2 of test block width direction, to try
Block is put into.
It is made of it is worth noting that, adjusting crane lifter plate 4, lifting leg 5, lifting foot 6, opens five tune in lifter plate
Bolt hole 9 is saved, one of them is located at the geometric center of rectangle lifting plate, and four additional is symmetrically lived apart on diagonal line；Adjust bolt
Equipped with adjusting bolt 7 on hole 9；In use, center adjusts bolt as main regulation bolt, other four are adjusted as auxiliary standby
Bolt.Two lifting legs are along test block width direction distance and two supporting legs along test block width direction apart from identical.On every lifting leg
Four limit fixed bolt holes 10 are respectively set, are limited on fixed bolt hole 10 equipped with limit fixing bolt 8.Every lifting leg sets one
Lifting foot, to realize the lifting of upper joint test specimen 17.
In addition, lift adjustment joint opening width range is by support leg length and adjusts bolt length co-determination, therefore support
Leg length and adjusting bolt length need to determine by testing.
The working principle of this specific embodiment::
