Umbrella Arch Systems
Male / Female Coupling
FATE Engineering male / female couplings are critical connection elements for the safe and durable operation of Umbrella Arch Systems.
About the product
Male / Female Coupling
The Male/Female Socket is a critical accessory that ensures the safe and accurate connection of steel pipe umbrella arches in Umbrella Arch Systems. This connector enables seamless pipe assembly in long installations and maintains the integrity of the system.
The sockets are manufactured from high-strength steel, ensuring a secure connection under heavy loads and challenging ground conditions. They facilitate pipe alignment during installation and increase system stability. Designed to accommodate various diameters and standards, they are suitable for a variety of projects.

Tunnel
Two-Slot Ring Bit
An annular drill bit fitted to the front of the pipe-umbrella tube, working together with the pilot bit. While the pilot bit drills the centre of the hole, the ring bit enlarges it to the diameter needed for the tube to advance. In weak geological conditions, such as fault zones, weathered and blocky rock or loose ground, the hole often collapses and drilling becomes difficult. Because the tube advances with the drilling, the hole is kept open and the umbrella tube is placed directly in position. When drilling is complete, the pilot bit is released from the ring bit’s two-slot connection and withdrawn through the tube; the ring bit remains in the ground with the tube. Tungsten carbide buttons on the face break the ground, while flushing channels help carry the cuttings out.

Tunnel
Three-Slot Ring Bit
An annular drill bit at the front of the pipe-umbrella tube, working together with the pilot bit. While the pilot bit drills the centre of the hole, the ring bit enlarges it to the diameter needed for the tube to advance. Advancing the tube with the drilling keeps the hole open and places the tube in position, especially in loose and collapsing ground. The three-slot connection transfers rotation and impact from the pilot bit to the ring bit. Tungsten carbide buttons on the face break the ground, while flushing channels help clear the cuttings. When drilling is complete, the pilot bit is released from the connection and withdrawn through the tube; the ring bit remains in the ground with the tube.

Tunnel
Two-Slot Pilot Bit
The centre drill bit used together with the ring bit in pipe-umbrella drilling. While drilling the centre of the hole, the pilot bit transfers rotation and impact to the ring bit through its two-slot connection. The ring bit then enlarges the hole to the diameter needed for the tube to advance, and the tube is placed as drilling proceeds. Tungsten carbide buttons on the face break the ground, while flushing channels help clear the cuttings. When drilling is complete, the pilot bit is released from the ring bit and withdrawn through the tube for reuse; the ring bit remains in the ground with the tube.

Tunnel
Three-Slot Pilot Bit
The centre drill bit used together with the three-slot ring bit in pipe-umbrella drilling. While drilling the centre of the hole, the pilot bit transfers rotation and impact to the ring bit through its engagement faces. The ring bit enlarges the hole to the diameter needed for the tube to advance, and the umbrella tube is placed as drilling proceeds. Tungsten carbide buttons on the face break the ground, while flushing channels help clear the cuttings. When drilling is complete, the pilot bit is released from the ring bit and withdrawn through the tube for reuse.

Tunnel
Umbrella Pipe
A steel pre-support tube installed before excavation from around the tunnel face in the direction of advance, along the crown at a slight outward angle. Installed side by side, the tubes form a protective umbrella above the section to be excavated, limiting ground movement and helping to maintain stability during excavation. Mainly used at portals, in fault zones and in weak, weathered and collapsing ground. Successive umbrellas overlap to provide continuous pre-support along the drive. With the pilot bit and ring bit system, the tube advances into the ground as drilling proceeds. When drilling is complete, the pilot bit is withdrawn; the tube and ring bit remain in the ground. Where required by the design, grout is injected through the tube and its injection holes to fill voids between the tube and the surrounding ground. Tube diameter, wall thickness, length, connection type and overlap length are selected according to ground conditions, tunnel geometry and the support design.
