Which Types of components use in Tunnel Support System

A tunnel support system uses components like rock bolts, steel arches, shotcrete (sprayed concrete), and ground stabilization (grouting) to ensure tunnel stability by reinforcing surrounding rock/soil, preventing collapses, and managing water, often involving primary (immediate) and secondary (permanent) linings for safety and durability, adapting to various geological conditions.

Key Components of Tunnel Support System

  • Rock Bolts/Cable Bolts: Long threaded rods or cables anchored into the rock mass to provide reinforcement and prevent falls.
  • Shotcrete: Pneumatically sprayed concrete (wet or dry mix) applied to the tunnel surface, often with steel mesh, for rapid consolidation and lining.
  • Steel Sets/Arches: Structural steel ribs installed in softer ground or weak rock to distribute loads and provide stabGrouting: Injecting cementitious material into fractures in the rock to improve strength and reduce water flow.ility.
  • Grouting: Injecting cementitious material into fractures in the rock to improve strength and reduce water flow.
  • Lining Rings: Pre-cast concrete segments forming the permanent inner lining, especially in soft ground.
  • Mesh/Netting: Steel mesh or rockfall netting to catch debris, often used with shotcrete.

What are the Support Strategies of Tunnel Support System

  • Primary Support: Immediate stabilization, including rock bolts, steel arches, and initial shotcrete layers.
  • Advanced Support: Measures taken ahead of excavation in very weak ground, like pipe sheds.
  • Secondary Lining: A permanent lining (e.g., concrete) often applied after primary support for long-term stability, protection, and waterproofing.
  • Waterproofing: Membranes and sealants between linings to control water infiltration.

What are the Purpose of Tunnel Support System

  • To maintain the tunnel's shape and prevent deformation.
  • To protect workers and equipment from rockfalls and collapses.
  • To manage water ingress and protect the structure from corrosion.
  • To adapt support to complex geological challenges.

JB-14 STEEL PIPES -SCAFFOLDING

Jb-14 Steel Scaffolding Pipes (Pipes & fittings) is a core part of our business, we concentrate on producing high quality scaffolding pipes. Galvanized Pipes has long been one of the most used access materials in India. Scaffolding Pipes are galvanized to reduce rust and corrosion for a longer product life. Scaffolding Pipes also integrates into access scaffolding and is frequently used in power plants, refineries and petrochemical plant environments

Pipe Roofing System is a support system used in loose ground conditions in conventional and mechanized tunneling.

TYPES OF STEEL PIPES SCAFFOLDING

JB Engineering are manufacturer of high quality range of Concrete Batching Plant spares, Concrete Pump Spares ,transit Mixer Spares, Boom Placer Spares etc.

BIRDCAGE  SCAFFOLD

BIRDCAGE SCAFFOLD

A Birdcage Scaffold is an independent scaffold that has more than two rows of standards in both directions that are connected by ledgers and transoms. It is mainly used for work carried out on a single level, for example ceilings. You should refer to its specifications when erecting and dismantling birdcage scaffolds made from modular scaffolding.

TRESTLE  SCAFFOLD

TRESTLE SCAFFOLD

A Trestle Scaffold is assembled from prefabricated trestles, braces and accessories. Trestle scaffolds, for example A-frame and H-frame trestle scaffolds are commonly used by bricklayers, plasterers and painters and for general fit-out and finishing work. Trestle scaffolds generally do not require a licensed scaffolder to erect or dismantle.

scaffolding pipe with coupler

STEEL PIPES AND COUPLER SCAFFOLDS

These are built from Pipeing and joining or fixing components (couplers) fixed together to form the required scaffold design. They are frequently used on structures with unusual designs, shapes or functions. The versatility of Pipes and coupler scaffolds means they can be assembled in a wide variety of different configurations. This also means erecting pipe and Rebar Coupler scaffolds can be complex when compared to prefabricated scaffolds.

single pole scaffold

SINGLE POLE SCAFFOLD

A Single Pole Scaffold consists of a single row of standards connected by ledgers. Putlogs are fixed to the ledgers and built into the wall of the building or structure. A Single Pole Scaffold is dependent on the structure against which it is placed for support. It is important that no components of this type of scaffold are removed until the scaffold is being dismantled.

swing stage scaffold

SUSPENDED (SWING STAGE) SCAFFOLD

A suspended scaffold incorporates a suspended platform capable of being raised or lowered when being used. An example of a suspended scaffold is a swing-stage scaffold.

mobile scaffolding procedure

TOWER AND MOBILE SCAFFOLDS

A tower scaffold is an independent scaffold that has four vertical standards connected longitudinally and transversely, or two frames in plan connected transversely to create a scaffold of one bay. A mobile scaffold is a tower scaffold mounted on wheels.

hanging scaffolding procedure

HUNG SCAFFOLD

A Hung or Hanging Scaffold is an independent scaffold that hangs from another structure but can't be raised or lowered when in use.

Pre-fabricated scaffolding is an alternative term to modular scaffolding.

PREFABRICATED SCAFFOLDING

This is defined as an integrated system of prefabricated components manufactured in such a way that the geometry of assembled scaffolds is pre-determined’. It can include modular, tower, cantilever, hung and suspended (swing-stage) scaffolds and must be design registered as required under Section 1 of Schedule 5 to the model WHS Act 2021 Regulations.
