Types of shoring; raking shore

Short answer

The three types of shoring are raking, flying, and dead shores. Raking shore uses inclined rakers at 60-70° from a sole plate on ground to a wall plate with needles on the wall, secured by cleats and braces. It supports leaning or bulging external walls where open ground is available, with rakers spaced 3-4.5 m apart.

List out different types of shoring. Explain raking shore with necessary sketch.

Types of shoring

  1. Raking (inclined) shore
  2. Flying (horizontal) shore
  3. Dead (vertical) shore

Raking shore

Raking (inclined) shore: inclined members (rakers) support a wall from the outside. Rakers are at 60-70 degrees to the ground and are fixed at the top to a wall plate (with needles) bolted to the wall, and at the bottom to a sole plate resting on a firm base. Cleats and braces hold the members together.

Types: simple (single raker), compound/double (two or more rakers on different levels), and multiple raking shores for high walls (up to three storeys).

Parts: wall plate, needles, rakers, cleats, braces, sole plate and wedges. Use: to support an external wall that is leaning, bulging or undergoing alteration, where open ground is available. Spacing: rakers are placed at 3-4.5 m c/c along the wall.
