FUNCTIONS AND BENEFITS OF LARGE-SCALE TRENCH SHORING Cost Effective Work Processes Less Filling In and Compacting When and why are shoring systems used? Making excavations safe Large-scale trench shoring systems are excellently suited for this purpose. SBH Trench Shoring Systems are approved by BG BAU – the German Social Accident Insurance Institution for the Building Trade – and are either GS approved and/or issued with a Type Examination Certificate. This certification is based on extensive, certified structural calculations, which are partially substantiated by extensive trials and...

AN OVERVIEW OF SHORING PLANNING What factors have an influence on the choice of shoring system? Trench Depth and Course of Terrain Soil Conditions Ground Water Additional Loads (Traffic / Buildings) Pipe Length and Diameter Earth pressure loads The earth pressure load increases with the depth of the trench. Other factors which also have an influence on earth pressure loads are: ➥ course of terrain along edge of excavation ➥ slopes or embankments ➥ soil conditions ➥ ground water levels ➥ loads arising from building site traffic or tracks ➥ loads from foundations of buildings close to...

Trench depth and choice of shoring system Shoring Boxes or Rolling Strut Shoring? The type of system you use depends on the depth of the trench. In our opinion, the installation depth at which a line should be drawn is 4.00 m. This may, however, make it impossible to lower the sides of the box alternately all the way down to the bottom of the trench or to pull the plates out of the trench because of the excessive friction between the earth and the plates themselves. Plate lengths An example from the field with SBH Series 750 Rolling Strut Shoring The length of the individual pipes...

SHORING SYSTEMS USING THE CUT AND LOWER METHOD If the soil is unstable, the shoring box is installed by lowering it into the trench and alternately pushing the sides downwards. Installing the top boxes Top boxes are used for deeper trenches. The boxes are pre-assembled so that their width matches the width of the trench. Attach certified chains to the lifting eyes on the posts of the top box, align the box over the base box and connect both boxes using box connectors and pins. Continue the installation as previously described by alternately excavating and then pushing down the plates....

with slot together extension pipes for different trench widths Other systems use extension pipes or connecting pieces which have to be laboriously screwed together. This not only costs time but also requires a large amount of screws. The system used by SBH is different. The pipes are simply slotted together and secured with a single spindle pin and an R-clip. The plates and the spindles are connected via a joint-mounted spring spindle holder. This allows the plates to be pushed alternately into the trench when the cut and lower method is used. Spindles for extremely high loads The spindles...
