Abstract

The invention relates to the technical field of geological disaster prevention and treatment, in particular to a dangerous rock support and a support treatment method applying the same. The dangerousrock support comprises a supporting mechanism used for supporting a dangerous rock mass, the supporting mechanism comprises a plurality of vertically-arranged supporting columns, a plurality of transversely-arranged tying rods fixed to the plurality of supporting columns and a plurality of tying anchor rods, one ends of the supporting columns are anchored into a footing of a mother rock, the otherends of the supporting columns abut against the side, close to the free face, of the dangerous rock mass, the ends, abutting against the dangerous rock mass, of the multiple supporting columns incline towards the inner side of the free face, one ends of the tying anchor rods are anchored into the mother rock, and the other ends of the tying anchor rods are fixed to the supporting columns. According to the dangerous rock support and the support treatment method applying the same, the effect of solving the problem that the dangerous rock mass treatment effect is poor.

Description

technical field [0001] The application relates to the technical field of geological disaster prevention and control, in particular to a dangerous rock support and a support treatment method using the same. Background technique [0002] Dangerous rock mass is a potential collapse mass formed by cutting structural planes on steep slopes. refer to figure 1 , is a common falling dangerous rock mass, the dangerous rock mass 1 is located at the top of the parent rock 11, and forms a free surface 12 between the footing of the parent rock 11 in the vertical direction. Before being destroyed, the dangerous rock mass 1 is connected with the parent rock 11, and gradually separates from the parent rock 11 under various effects such as gravity, weathering and stress, and falls. [0003] For this type of dangerous rock mass, the treatment method of related technologies is to add pillars vertically on the free face to form support for the dangerous rock mass and reduce the chance of the ...
