Trench Boxes: Typical Installation Methodology

This quick and easy method ensures ground stability within a trench and helps minimise the excavation area to avoid damage to neighbouring structures and utilities in the ground. This methodology is best suited for trench boxes with shorter struts, if you use a trench box with long struts then other methods may be more suited, if you have any questions on different methods you can use contact our technical department.

Manhole Box

Manhole Box

Manhole boxes are similar to trench boxes in their basic function, but they incorporate integral end return panels for extra ground support when placing pre-cast manhole rings, as an alternative to sheets and frames. There are five available sizes catering to common manhole ring sizes. They can be quickly assembled and installed without an operator needing to enter the unsupported excavation, supporting trenches up to 5.5m using the base module and various struts. Ideal for most ground conditions.

Hi-Clear Manhole Box

Hi-Clear Manhole Box

Hi-Clear Manhole box posts allow the connection of a base unit to a top unit, providing a 4m high box with only two struts as opposed to three. The lower strut is positioned higher in the assembly as to provide the added benefit of greater under-strut clearance. This improves height-to-width ratio, a crucial requirement when large diameter pipes and chambers need to be installed. The Hi-Clearance system uses a unique fixed length strutting system that is available in three different lengths.

Groundforce offer a wide range of trench box sizes with various strut types, providing a safe solution on site. Trench boxes are versatile, cost-effective and provide an excellent way of protecting workers from excavation wall collapse while carrying out groundworks. They can easily be stacked and used in multiple runs, which also makes them the ideal shoring method for continuously supporting an extended length of trench. Some of the key benefits are:

Backhoe Trench Box

Backhoe Trench Box

The Backhoe Trench Box is a lightweight yet robust solution for small trenching applications. With a load capacity of 20 kN/m2, it can be used to depths of 4 metres in most soil types. It's ideal for use on building sites and construction projects where small excavator handling is essential. Developed to meet the needs of the contractor when using smaller 180 degree backhoe rubber tyred excavators, this box is supremely light yet provides solid support.
