Abstract
The invention discloses a steel protection rail trolley used for borehole-blasting method construction of tunnels in moderate and above rock burst regions. The steel protection rail trolley comprises a cave-shaped steel protection framework, and a bottomless protection steel plate fixed on the steel protection framework in the length direction, wherein an I-shaped steel framework is welded above the top of the steel protection framework; a steel strand protection net is anchored on the steel framework; a plurality of wheels are mounted at the lower edge of the steel protection framework along the length direction of the steel protection framework; a detachable front end top plate is arranged at the front end of the steel protection framework; a plurality of rows and lines of shot holes for borehole-blasting positioning are formed in the front end top plate; a steel-made safety door is arranged at the lower part of the front end top plate; and furthermore, movable steel rails, which are mounted in the construction field, are arranged. Under the protection of the protection net, the steel protection rail trolley has a buffering effect on the falling of rock-burst falling stones so that a steel protection structure is protected, constructors are protected, and furthermore, the aim of safety construction is guaranteed. The disadvantages of a traditional construction method that a construction period is long, potential safety hazards are great, and the distribution of borehole-blasting shot holes is complicated are avoided; and the steel protection rail trolley has the advantages of simplicity in operation, low cost, safety guarantee, rapid construction progress and the like.
