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 boxes available to cater for standard 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 various strut types. A 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.
