Description
Technical field
The present invention relates to a kind of test mould, relate in particular to a kind of mould that is used for the crack-containing bolting test of shop experiment.
Background technology
In energy development, mining and cut slope, exist come in every shape, the having intense influence and restricting the behavior of rock mass of joint plane that scale is different, these joint planes.The mechanical behavior of the rock mass under load action is actually the concentrated expression of its immanent structure face.Rock mass engineering project practice many times both at home and abroad shows, the unstability of rock mass engineering project, and great majority are owing to the expansion of defectives such as its inner joint, crack causes.Be the deformation failure of restriction rock mass, anchor pole commonly used is reinforced in the rock mass engineering project.A large amount of bolt anchorages that adopt in China's mine working, railway tunnel and all kinds of underground works.The reinforcement effect of anchor pole is fairly obvious, especially in the joint fissure rock mass.But also lack the further investigation of three-dimensional fracture expansion and anchor pole at present to three-dimensional jointed rock mass crack arrest mechanism.
Similar test is the effective ways of this problem of research, and still, how crack and anchor pole are set in class rock material or analog material is the successful key of research, and solution to this problem just is to make on the mould of test specimen.At present, be used for making mould kind that class rock material or analog material contain the crack and add the anchor test specimen seldom, and the more complicated all of several moulds seldom, on the one hand, the complex manufacturing technology of mould own, the processing cost that gets up is very high; On the other hand, making test test specimen flow process is loaded down with trivial details, uses inconvenience, and is time-consuming, and can't firmly fix anchor pole, can not effectively simulate the reinforcing crack arrest effect of anchor pole to the crack.
Summary of the invention
For overcoming above-mentioned the deficiencies in the prior art, the invention provides that a kind of fabrication and processing is convenient, simple in structure, easy accessibility, can reuse, cost is low, the succinct mould that is used for crack-containing bolting test of processing test specimen flow process.
The objective of the invention is to adopt following technical proposals to realize: a kind of mould that is used for crack-containing bolting test, comprise base, base is provided with base plate, vertically be provided with side plate, end panel and vertical connecting part on the base plate, the both ends plate vertically is plugged between the two ends of biside plate respectively, surround the framework of a upper opening jointly, two vertical connecting parts are arranged at respectively between the biside plate of outside, framework two ends, between the biside plate by being connected with vertical connecting part horizontal brace rod spare connected vertically; The base plate center is provided with fixedly crack device, and fixedly the crack device is provided with plastic tab.
Be symmetrically arranged with cannelure and end hole on the described side plate, the two ends of end panel are placed in the cannelure.
Described end panel is provided with some borings.
Described horizontal brace rod spare passes the end hole on the side plate, horizontal brace rod spare end and middle female A of butterfly and the hole that is respectively equipped with on the horizontal direction, and the vertical connecting part passes the hole.
The female B of butterfly on the vertical direction is arranged at described vertical connecting part top, and the bottom is connected with base plate with spring shim by nut.
Described fixedly crack device comprises truncated cone-shaped hole, semicircle stage body, latch and screw, the truncated cone-shaped hole is positioned at the base plate center, be provided with two semicircle stage bodies in the truncated cone-shaped hole, clamping has plastic tab between the two halves Rotary-table, and the two halves Rotary-table is connected by web member with the latch of base plate bottom.
The height of described semicircle stage body is less than the thickness of base plate.
Described web member is screw or screw or bolt.
Be provided with scale value around the truncated cone-shaped hole on the described base plate downside.
The present invention in use, after crack, anchor pole fixed, fastening each nut was poured into semisolid class rock material or analog material in the framework mould of being made up of side plate and end plates, fully vibrate, through after certain curing period, i.e. collapsible die.During form removal, unclamp the female A of butterfly on the side plate earlier, the side plate of dismantling is torn the device in the fixedly crack of bottom again open, tears base plate and end panel at last open.In addition, can according to the scale value on the base plate, the crack of different angles be set according to designing requirement; By passing the different hole of end panel, the anchor pole of different angles is set.
The present invention compares with the mould that other are used for being provided with at test specimen crack and anchor pole, has following significant technical advantage and characteristics:
(1) simple structure, easy to process, cost is low.Used sheet material, nut or the like all are to have bought easily, and price is low, have very much economic advantages.
(2) assembling, convenient disassembly.The assembling of entire die is just fastening by several butterflies mothers and screw thread member, therefore, has shortened the average required time of each test specimen, has improved test efficiency.
(3) controllability.Can the crack of different angles be set according to the angle index value on the base plate bottom surface, convenient and swift.The angle of anchor pole can realize by the different hole of passing on the end panel.Satisfy the requirement of different tests to crack and anchor pole angle.
(4) making test specimen flow process is succinct.The processing of whole test specimen roughly divided for three steps can finish the first step: crack and anchor pole are set, fastening mould; Second step: cast class rock material or analog material, vibrate; The 3rd step: form removal.
