Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
Referring to attached drawing: this including U-shaped steel 2 and the hoist cable 1 being mounted under U-shaped steel 2 in the present embodiment, 1 blanket net of hoist cable is used
In fixed blanket net, 2 both sides of U-shaped steel are equipped with fixed plate 4, and fixed plate 4 is equipped with screw hole 9, installs swell fixture 5 in screw hole 9,
The swell fixture 5 passes through the drilling 6 of perforation ravelly ground 7, and secured rock stratum 8 is protruded into the drilling 6, and the swell fixture 5 is solid
It is scheduled on secured rock stratum 8.Fixed plate 4 not only acts as the effect of fixed expansion screw 5, and there are also the effects of support.Swell fixture 5 is installed
