Description
Technical field
The present invention relates to Geotechnical Engineering field, particularly a kind of intersection at random that makes runs through the mould of crack 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.Due to the difference of the factors such as the spacing of rock mass, length, connected ratio, inclination angle, when the rock material containing many group fissure-planes is studied, class rock test block makes extremely difficult.Current model test method mainly adopts concrete as the material of rock test block.And the fissure-plane mode that makes rock interior 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, crack is in Practical Project, and the form usually intersected for two or more pieces crack, traditional method can only carry out the simulation test of Single Fracture.
2, crack adjustment difficulty is relatively big, often adjusts a crack and will again make mould, inefficiency, and the process-cycle is long, and waste mold materials.
Summary of the invention
For overcoming the deficiencies in the prior art, the present invention provides a kind of and makes the random mould intersecting and running through crack sillar.
To achieve these goals, the present invention adopts following technical proposals:
A kind of intersection at random that makes runs through the mould of crack sillar, including mould, loose-leaf, square location-plate, steel pole, rectangular retaining plate, bolt.It is characterized in that: described mould includes four side plates and lower shoe, all detachably；Side plate height is higher than the height of prefabricated sillar, and long side plate hight goes out the reserved opening of prefabricated sillar elevation-over, facilitates moulding by casting material；Reserved overthe openings arranges along long side direction line slideway groove, and steel pole can be inserted into guide-track groove and along guide-track groove longitudinal sliding motion, is bolted position；Square location-plate side is provided with draw-in groove, may be stuck on steel pole and slides laterally along steel pole；The loose-leaf that four steel disc compositions are free to rotate, fixes the position of steel disc in the pre-formed joint of the loose-leaf square location-plate of insertion；The line slideway groove of long side plate is provided above the groove along long side direction, and rectangular retaining plate inserts in the groove of long side plate, withstands loose-leaf, it is prevented that when vibrating, loose-leaf moves.
Arranging gear-like opening inside described square location-plate, the angle of gear adjacent teeth is 5 °～30 °, and loose-leaf inserts the angle of the tooth adjustment prefabricated crack of square location-plate different angles；
The present invention realizes the crack random arrangement in plan-position by vertically moving steel pole and transverse shifting location-plate；By changing the width in loose-leaf width adjusting crack；Obtain the random intersection of many groups with multiple square location-plates and run through crack.
Relative to prior art, there is advantages that
1, this mould uses loose-leaf to achieve to intersect and run through the making of crack test block.
2, by the cooperation of square location-plate and steel pole, it is possible to achieve crack angle, length, the random of spacing regulate, and simulate random crack rock, save material, simple to operate, reusable.
3, have hole on the top of the long side direction of mould, Binder Materials can be added after installation fixes mould easily.
