Description

Rock excavation device capable of continuous construction of and rock drilling and rock spitting and rock excavation method using the same}

The present invention relates to a rock excavation apparatus and a rock excavation method, and more particularly, comprises both a rock drilling unit for drilling a hole in the rock and a halam unit for inducing a crack in a hole formed in the rock mass. The present invention relates to a rock excavation device capable of continuous construction of rock rock and rock rock, and a rock excavation method using the same, which is made to enable continuous progress and enables more precise construction through fine angle adjustment of the rock rock unit and the rock rock unit.

In general, it is required to excavate or remove rock mass during the excavation process for constructing an underground tunnel.

The representative method of rock excavation is a method of drilling a hole in the rock and installing an explosive in the hole to blast.

While this drilling blasting method is economical and has the advantage of being able to flexibly cope with various geological conditions, vibration and noise generated during blasting work in dense urban areas or in areas with approvals or livestock houses in the vicinity, due to the occurrence of various civil complaints. There is a problem with many difficulties in proceeding.

In consideration of the problem of the drilling blasting method, a vibration-free rock excavation method using a rock drill and a rock drill is used.

The vibration-free rock excavation method consists of drilling a hole in the rock mass using a rock drill, and crushing the rock mass in the form of splitting the rock mass by inserting a granulator into the drilled hole.

In this way, since the vibration-free rock excavation method does not use explosives, but induces the crushing of the rock mass using a granulator, it is possible to significantly reduce vibration and noise generated during the excavation process of the rock mass.

However, in order to excavate rock using a rock drill and a rock drill, first install a rock drill on the boom of the excavator to drill a hole in the rock, and when all holes for a predetermined position are drilled, separate the rock drill from the excavator. After that, the granulation machine is mounted on the excavator to perform the granulation work.

As described above, in the related art, as the rock drill and the rock drill are independently configured and are mounted on each of the excavators, it is difficult to continuously work between the rock drill and the rock drill, and it takes a lot of time to install and remove the rock drill, and to install and remove the rock drill. There is a problem in that the efficiency of work is deteriorated as the precise operation of the driver is required in inserting the tip of the granulator into the formed hole.
