Problems solved by technology
[0007] 1. In actual engineering, cracks are often in the form of two or more cracks intersecting. Traditional methods can only carry out simulation tests of single cracks.
[0008] 2. It is very difficult to adjust the gap. Every time the gap is adjusted, the mold must be remade. The work efficiency is low, the processing cycle is long, and the mold material is wasted

Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings.
[0023] Such as Figure 1-Figure 3 As shown, a mold for making random intersecting and penetrating fractured rock blocks includes forming molds, loose leaves, square positioning plates, steel rods, rectangular fixing plates, and bolts. It is characterized in that: the internal size of the forming mold is 150mm×150mm×300mm, including two long-side side panels 7, two short-side side panels 5 and a lower bottom panel 8, all of which can be disassembled, and the thickness of the panels is 10mm. The junction with the plate is tightly embedded and buckled through grooves, and tightened and reinforced by nuts 10 and 11 to form a molding mold with no top cap; the height of the side plate is higher than the height of the prefabricated rock block, and the side plate on the long side is higher than the prefabricated rock block An opening 12 is reserved above the height, which is ...

The invention belongs to the field of geotechnical engineering, and in particular relates to a mold for making random intersecting and penetrating rock blocks with cracks. Including forming die, loose leaf, square positioning plate, steel rod, rectangular fixing plate, bolts. It is characterized in that: a linear guide rail groove along the long side direction is set above the side plate of the long side, and the steel rod can be inserted into the guide rail groove and slide longitudinally along the guide rail groove; the random arrangement of the cracks in the plane position is realized by moving the steel rod longitudinally and moving the positioning plate laterally . The inside of the square positioning plate is provided with a gear-shaped opening, and the loose leaf is inserted into the teeth of different angles of the square positioning plate to adjust the angle of the prefabricated crack; the loose leaf is inserted into the prefabricated seam of the square positioning plate to fix the position of the steel sheet; changing the width of the loose leaf adjusts the width of the crack. The invention can realize the simulation of various fissure rocks with different fissure angles and different fissure widths, and has a wide range of applications.
Description
technical field [0001] The invention relates to the field of geotechnical engineering, in particular to a mold for making randomly intersecting and penetrating rock blocks with cracks. Background technique [0002] The 21st century is the century of underground engineering. Underground hydropower stations, large-scale mine roadways, underground railways, river crossing tunnels, underground oil storage caverns, etc. are all being built on a large scale at home and abroad, and the research focus of rock mechanics is increasingly shifting to underground. In the construction of underground engineering, fractured rock mass exists widely, and the stability of joints and fissures plays a vital role in the safety of the rock mass structure of the entire underground engineering to a certain extent. Intermittent fractured rock mass is the most widely distributed one of the forms. The randomness of the distribution of rock mass fissures, the diversity of shapes, the inhomogeneity of d...
