Background
Rock fracturing refers to drilling holes in rock and concrete, and then applying a static (or quasi-static) load to the hole wall to fracture or break the rock. Because it breaks rock from the inside of rock or concrete, the characteristic that the tensile strength of rock or concrete is much lower than the compressive strength (the tensile strength is about one tenth of the compressive strength) can be fully utilized. At present, a plunger type hydraulic splitting rod is generally adopted as a pressing device for rock splitting, but the force applied to the rock by a hydraulic roof block of the plunger type hydraulic splitting rod is only concentrated in the top area of the roof block, and the pressing mode is not beneficial to uniform rock breaking of the rock.

Specifically, the hydraulic roof blocks are equidistantly arranged on the side part of the plunger type hydraulic splitting rod from top to bottom.
Specifically, the front end of the hydraulic jacking block is provided with an arc matched with the arc-shaped base plate.
Specifically, the arc backing plate extends to the part outside the drilling hole and is also provided with a hanging ring.
Specifically, the hanging ring is in threaded connection with the arc-shaped base plate.
Compared with the prior art, at least one embodiment of the utility model has the following beneficial effects that the arc-shaped base plate is arranged between the wall of the drilling hole and the hydraulic roof block of the plunger type hydraulic splitting rod, the hydraulic roof block of the plunger type hydraulic splitting rod acts on the arc-shaped base plate after being pushed, and the arc-shaped base plate uniformly acts on the rock by the concentrated force exerted by the hydraulic roof block, so that the aim of uniformly breaking the rock is fulfilled, and the energy utilization rate can be effectively improved.
