Dangerous rock protection structure and method for road engineering construction

The invention discloses a dangerous rock protection structure and method for road engineering construction. The dangerous rock protection structure comprises a protection net and mounting pins. The protective net is composed of an installation frame and a woven net, the woven net is installed on the installation frame, the number of the installation pins is multiple, an operation pipe is installed on each installation pin, and an installation rope is fixedly connected to the operation pipe through a protective mechanism. After a protective net is installed, when external wind power is large, the protective net drives a sliding plate to slide in an operation pipe through an installation rope, in the sliding process of the sliding plate, operation of the installation rope is decelerated through elastic force generated by stress deformation of a spring, and in the process that the protective net drives the installation rope to move, the operation of the installation rope is accelerated. And the mounting ropes do
