Abstract

The invention discloses a device used for simulating diffusion and expansion characteristics of slurry in a vertical fracture of rock mass. The device includes a base seat, grid plates, support plates, rock mass debris layers and pressure sensors. The grid plates include a first grid plate and a second grid plate. The first grid plate and the second grid plate are fixedly disposed on the base seat. The support plates include a first support plate and a second support plate. The first support plate and the second support plate are respectively connected with the first grid plate and the secondgrid plate. The rock mass debris layers include a first rock mass debris layer and a second rock mass debris layer. The first rock mass debris layer and the second rock mass debris layer are respectively attached to the first support plate and the second support plate. Gasket pieces are embedded between two end sides of the first rock mass debris layer and two end sides of the second rock debris layer. The first rock mass debris layer, the second rock mass debris layer and the gasket pieces enclose a vertical fracture. The pressure sensors are disposed on the support plates. The diffusion andexpansion characteristics of the slurry in the vertical fracture of the rock mass can be simulated, and grouting construction quality is ensured.

Description

technical field [0001] The invention relates to the technical field of rock mass reinforcement, in particular to a device for simulating the diffusion and expansion characteristics of grout in vertical cracks of rock mass. Background technique [0002] Due to the interaction of wind erosion, water erosion, freeze-thaw and gravity erosion, rocks often present a composite erosion mode. [0003] Massive erosion usually occurs in the rock mass, and there are a large number of vertical fissures, which constitute channels for water to infiltrate. The arsenic sandstone block is completely separated from the parent body, resulting in a tendency of falling and overturning. When it reaches a certain limit state, it will suddenly collapse, forming a block-like gravity erosion. [0004] Collapse of rock masses on slopes often leads to serious consequences. For example, collapse of rock masses on slopes on both sides of the road will interrupt the road, and even endanger the lives and p...
