Embodiment approach

[0032] Taking the structural surface sample of simulating 4cm * 4cm * 4cm as an example below, the embodiment of the present invention is illustrated as follows:

[0033] According to the size of the structural surface to be simulated, move the card slot on the C-type outer plate to the position where the scale of the A-type outer plate is 5cm, and tighten the screws to fix it; according to the size of 4cm, it can be seen that four 4cm×4cm× For samples with a 4cm simulated structural surface, 4 jackets can be placed on the B-type and C-type outer plates respectively, and one jacket can be placed on the outer plates with the indication scales of 4cm, 8.5cm, 13cm, and 17.5cm respectively. Tighten the screws on it to fix it with the outer plate; then select 3 curved boards with a width of 5cm and insert them into the slots at 4cm, 8.5cm, and 13cm respectively, and choose a flat board with a width of 5cm to insert 17cm In the slot at the place, the complete assembly of the mold un...

Abstract

The invention relates to a multi-scale mould for making and simulating a structural surface of a country rock. The multi-scale mould comprises an A-type outer plate, a B-type outer plate, a C-type outer plate, a bottom plate, a flat and straight plugging plate, a curved surface plugging plate, a plug pin, a buckle, a nut and a jacket. A shearing test of simulating the structural surface of a rock needs to use a mould to pour structural surface samples, and in order to research the influence of a scale effect on the shearing property of the structural surface, a plurality of structural surface samples with different sizes need to be prepared for the test, while, the two problems always exist alternatively that in a laboratory moulds with different sizes are difficult to provide and huge investment on customizing the moulds with different sizes is needed, so that the great waste is caused. Through the adoption of a structural surface mould capable of making multiple scales in the making process of the structural surface samples, not only can the structural surface samples with different sizes be made, but also the resource waste can be avoided, and the test cost is reduced.

Description

technical field [0001] The invention relates to the engineering field by adopting structural surface shear strength indexes for engineering design, in particular to a multi-scale mold for making simulated original rock structural surfaces. Background technique [0002] The structural plane of rock mass refers to the arrangement and combination of structural planes and structures in rock mass. The rock mass undergoes various geological processes to form geological interfaces with different characteristics, which are called structural planes; the structural planes divide the rock mass into rock blocks of different shapes and sizes, called structural bodies. Due to the existence of structural planes, the continuity and integrity of the rock mass will be destroyed, and the mechanical properties and stability of the engineered rock mass will be weakened. Therefore, it is necessary to study the relevant properties of the rock mass structural plane. [0003] When conducting exper...
