UMBRELLA ARCH IN UNDERGROUND EXCAVATIONS
SAYKOÇ MACHINERY provides solutions for safe progress in tunnels with self drilling pipes. This is a system formed by placing of steel pipes (3” to 4” diameter and 6m to 6m+3m: 9m) along the top of the tunnel to eliminate deformations in the tunnel and increase the self-retention period of the floor and increase the belt time in underground excavation applications such as tunnel, gallery in very weak, weak rock and unstable ground conditions.
THE ADVANTAGES OF THIS METHOD
1) Drilling is done with Jumbo
2) Don’t need a second DTH or Auger drilling machine investment.
3) Don’t need to drive a pipe after drilling. (Drilling made by the pipe)
4) Drilling process made by attaching SAYKOÇ made bits to the pipes.
