What Is Shoring & Types of Shoring Used In Construction

Shoring in construction refers to a temporary support system used to stabilize a building or structure during construction, repair, or demolition work. The purpose of shoring is to prevent collapse and ensure the safety of workers and the public.

The design and installation of shoring systems is a complex process that requires the expertise of experienced engineers and contractors. It is important to ensure that the shoring system is strong enough to withstand the weight of the structure and any external forces, such as wind or earthquakes.

Shoring in construction is completely different from retaining walls, as these are used only to retain the soil during the excavation. As per the structural designer, it is not used to only retain the soil. There are different types of shoring in construction such as raking shoring, hydrauic shoring, and soil nailing shoring each used for a specific purpose.

Shoring In Construction

Shoring is a temporary structure used to prevent the collapse of the main under-construction structure. The most common shoring support is required during the early stage of construction which is excavation.

Shoring is defined as Temporary support constructed to support and improve the lateral strength of walls and structures during repairs called Shoring.

Types of Shoring In Construction

The Following are the main four types of shoring,

1. Raking Shoring
2. Hydraulic Shoring
3. Beam and Plate Shoring
4. Soil Nailing Shoring

1. Raking Shoring

Raking Shores are constructed by placing one or more timber beams on the face of the structure to be supported and the ground.

Ranking shoring is more effective if the racer meets the wall at an angle of 60 to 70 degrees. The wall plates are generally used to increase the area of support.

2. Hydraulic Shoring

Hydraulic shoring is generally used hydraulic pistons which are pumped outward until they press up against the trench walls. This piston is normally combined with steel plate or plywood, either being 1-1/8″ thick plywood, or special heavy fenland 7/8″ thick.

3. Beam and Plate Shoring

Beam and Plate steel I-beams are first inserted into the ground and then the steel plates are slid in amongst them. A similar method utilized in the case of wood planks is called soldier boarding.

The hydraulic support used tends to be faster and easier; the other methods tend to be used for longer-term applications or larger excavations.

4. Soil Nailing Shoring

Soil nailing is a method of shoring in which an excavation, soil slopes, or retaining walls are strengthened by inserting reinforced elements in them like steel reinforcing bars. The hole in the soil is a pre-drilled hole and then grouted into place or drilled and grouted simultaneously.

These elements are generally inserted at a slight downward inclination which offers better protection against any drawdown action.
