Description
Technical field
The present invention relates to Geotechnical Engineering field, particularly a kind of mould making angle adjustable and width fissure-plane sillar.
Background technology
21 century is the century of underground engineering, and domestic and international underground power station, large-scale mine tunnel, underground railway, river-crossing tunnel, underground petroleum deposit cave depot etc., all in extensive construction, ROCK MECHANICS RESEARCH emphasis goes underground day by day.In underground engineering construction, crack rock is widely present, and the safety of the rock mass structure of whole underground engineering is had vital effect by the stability in joint, crack etc. to a certain extent, and intermittent joints rock mass is to be distributed one of form the most widely.The complexity of the randomness of rock cranny distribution, the multiformity of form, the inhomogeneities of distribution and spatial organization so that engineering exists the risk of unstability.For effectively evaluating the engineering stability of crack rock, it is necessary to carry out the mechanical test research of rock sample containing crack, effectively to disclose mechanical deformation characteristic and the failure law of fissure rock.
In rock mass, the existence of fissure-plane destroys integrity and the seriality of rock mass structure, the intensity of fissure-plane, deformation properties difference, result in the difference of the intensity of rock mass, deformation behaviour.In order to test and inquire into containing the characteristics of deformation and strengths organizing fissure-plane rock mass more, current main approaches is model experiment method.But, owing to the factors such as the fissure-plane spacing of rock mass, length, connected ratio and inclination angle are changeable and complicated, to when containing the rock material simulation experimentation organizing fissure-plane, the making of rocks test block is extremely difficult more.Current model experiment method mainly adopts concrete to be the material making rock test block, and the mode main method making rock interior fissure-plane is as follows:
(1) steel disc of pre-designed different size and different angles is inserted in mould, vibrate after casting concrete, before treating concrete initial set, extract steel disc, form fissure-plane；
(2) in test block model, thin-film material is imbedded in advance, isolation model material, form fissure-plane.
Said method has following deficiency:
1, fissure-plane positioning difficulty is big, often adjusts a fissure-plane parameter and need to again make mould, inefficiency, process-cycle length and waste mold materials.
2, it is difficult to the inclination angle of fissure-plane, position, length etc. in accurate simulation rock test block, causes that the degree of accuracy of test block is low, affect the reliability of experimental data.
When 3, adopting steel disc to make fissure-plane, if steel disc is more in test block, when concrete vibrating, steel disc position is susceptible to change, and the internal crack simulated is disorderly, is not inconsistent with initial design.
Summary of the invention
For overcoming the deficiencies in the prior art, the present invention provides a kind of mould making angle adjustable and width fissure-plane sillar.
For achieving the above object, the present invention adopts following technical proposals:
A kind of mould making angle adjustable and width fissure-plane sillar, including mould, strip stalloy, circular location-plate, connecting bolt, it is characterized in that: described mould includes four side plates and lower shoe, side plate and lower shoe are all detachable, circular location-plate is placed centrally the opening surface in mould, and steel disc inserts the position fixing strip steel disc in the prefabricated gap in circular location-plate.
Described circular location-plate is divided into identical upper and lower two-layer, is fixed by the bolt of both sides, and the gap on upper strata indicates scale along its length, by the size of the Interleaved control Fracture Width of two-layer circle location-plate.Circular location-plate is with function of angle gauge, and circular location-plate is penetrated the graduation mark of different angles by the center of circle to periphery, is used for the angle accurately measuring circular location-plate with mould.The angle of prefabricated gap and strip stalloy is regulated, it is thus achieved that the many groups of crack rock test blocks containing different crack dips and Fracture Width by rotating circular location-plate.
Relative to prior art, there is advantages that
1, this mould can complete the making of the crack test block of multiple crack angle and Fracture Width with the least possible material.The circular location-plate rotated is used to solve the making of many cracks class rock mass, adjustable crack angle, simple to operate, reusable.
2, interlocked by two-layer circle location-plate, scalable Fracture Width, simple to operate, reusable.
3, mold bottom arranges groove, adopts embedded fixing, is equipped with bolt and fixes, and when can guarantee that slip casting and vibrate, mould will not deform and even collapses, and enhances the stability of entirety.

Fig. 3 is double-layer circular location-plate schematic diagram.
In figure: 1 protractor graduation mark, 2 circular location-plate fixed screws, 3 prefabricated gaps, plectane on 4,5 times plectanes, 6 nuts 1., 7 studs 1., 8 nuts 2., 9 mould short side direction side plates, 10 studs 2., 11 mould base plates, 12 grooves, 13 mould long side direction side plates, 14 strip stalloys.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1-Figure 3, a kind of mould making angle adjustable and width fissure-plane sillar, including the rotatable double-layer circular location-plate with function of angle gauge of lower shaping mold and top, the strip stalloy making prefabricated crack and connecting bolt.Wherein, mould internal diameter size is 150mm × 150mm × 300mm, is made up of four side plates and a base plate, and plate thickness is 10mm, and face and junction, face are by the tight buckle of groove 12, it is ensured that slip casting and when vibrating mould will not misplace.Two side plates 13 of long side direction are buckled together with nut 6 and side plate 9 by stud 7, then combine with base plate 11 again through stud 10 and nut 8, the mould of one no ceiling of composition.The circular location-plate on top is made up of upper plectane 4, lower plectane 5 and screw 2.Upper plectane and lower plectane are all the circular slab that diameter is 350mm, and plectane precasts the crack to simulate.Position, upper and lower plates crack is identical with width, and upper plate 4 upper surface indicates the angle index line from center to week edge emitting, indicates and ranges for 0～360 °, can adjust the angle in crack during use according to the angle index line on plectane 4.Upper plate 4 and lower plate 5 can do small slip scalable Fracture Width along crack length direction, tightened by screw 2 and can fix upper and lower plates.Circle location-plate 4,5 is placed in directly over mould, then strip stalloy 14 is insert molded in mould preset crack via the gap of circular location-plate 4,5.
