The sheet pile shoring system consists of steel shoring plates which are guided in pre-installed H-piles and sunken down by the excavator to the required depth using the lower-and-cut method. Depending on the soil condition and the excavation depth, up to 3 layers of spindles are placed between the H-piles to support the earth pressure. The H-piles can be placed either by a vibrator and/or in predrilled holes to avoid any impact to nearby structures. In case of large building excavations the H-piles can also be supported by one or more layers of soil anchors.
Main applications:
- • Deep trenches for pipes and culverts
- • For large diameter pipes and structures
- • To support excavations for buildings
- • If pile driving by vibration is not possible
The sheet pile shoring system must always be designed according to the actual site conditions such as type of soil, ground water level, additional side loads, anchor position, etc. Special care has to be taken for the section modulus and the penetration depth of the sheet pile, the distance of the piles (plate length) and the pressure on the telescopic spindles.
