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] like 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 con...

The invention belongs to the field of geotechnical engineering, and particularly relates to a mold for manufacturing a random cross-through fractured rock matrix.The mold comprises a forming mold body, hinges, square positioning plates, steel rods, rectangular fixing plates and bolts, and is characterized in that the forming mold body comprises four side plates and a lower bottom plate which are all detachable, linear guide rail grooves in the direction of long sides are formed in the upper portions of the long-side side plates, the steel rods can be inserted in the guide rail grooves and can longitudinally slide along the guide rail grooves, clamping grooves are formed in the lateral sides of the square positioning plates, the square positioning plates can be clamped on the steel rods and transversely slide along the steel rods, and the random layout of fractures at the planar position is achieved by longitudinally moving the steel rods and transversely moving the positioning plates.A gear-shaped opening is formed in each square positioning plate, the angle between every two adjacent teeth of each gear is 5-30 degrees, the angle of each prefabricated fracture is adjusted when each hinge is inserted in the spaces between the teeth at different angles of the corresponding square positioning plate, the position of a steel sheet is fixed when each hinge is inserted in the prefabricated fracture of the corresponding square positioning plate, and the width of the fracture is adjusted by changing the width of the hinges.The simulation of various fracture rock with different fracture angles and fracture widths can be achieved, and the application range is wide.
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...
