Boxes

Altrad Generation Trench Boxes are simple-to-assemble, two-sided excavation support systems
designed to be installed by an excavator utilising the ‘dig and push’ or ‘excavate and lower’
techniques. Trench boxes are often used where rapid installation of utility pipelines and trench
runs are required. Trench Boxes provide a safe working environment for those on-site by safely
withstanding the surrounding soil pressure. Trench Boxes can be used in conjunction with
four-sided Manhole Boxes to provide complete protection for personnel. Drag Boxes offer
a speedy alternative to a Trench Box when laying long pipe runs. If the Permissible SWL is
exceeded, ALWAYS enquire about our design service.

Drag Boxes are a speedy alternative to Trench
Boxes, where speed of production is paramount.
The Drag Box is used in stable, self-supporting soil
conditions, and is lowered into a pre-dug trench.
Then, with the aid of an excavator, it is dragged
along via the front strut as pipe production moves
along the trench. In order to enable this, a Drag
Box has a cutting edge on the front of the box
rather than at the bottom. Drag Boxes also tend
to be used on green or brown field sites, where
there are no services or obstructions. Drag Boxes
should only be used as a shield not as a support.

• Lifting points for safe slinging
• For use in self-supporting soil
• Standard Drag Box 4 Struts
• Can be used in conjunction with Manhole Boxes

Manhole Boxes are similar to Trench Boxes in their basic function, however they incorporate
integral end return panels thus providing additional ground support, making them ideal for
installing pre-cast manhole rings in trench runs as an alternative to using sheets and frames.
There are six sizes of Manhole Box available to cater for common sizes of pre-cast manhole
rings. Each box can be assembled and installed quickly and without the need for an operative
to enter the unsupported excavation. Manhole Boxes can be used in most ground conditions to
support trenches with depths of up to 5.3m by utilising the base module with two box tops and a
variety of different strut types. Trench Guard Edge Protection system is available for this product.
Four-way handling points to aid safe assembly.

Groundwork box ancillaries are supplementary components and accessories that complement and enhance the functionality of our groundwork boxes. These ancillaries are designed to provide additional features, convenience, and versatility to construction and utility projects that involve underground infrastructure, such as electrical, plumbing, or telecommunication installations.

Groundwork box ancillaries are integral components that enhance the usability, safety, and longevity of underground infrastructure systems. By offering features such as protection, organization, security, and accessibility, these ancillaries contribute to the overall effectiveness of groundwork boxes and support successful construction and utility projects.
