Tricel Rigofill - Stormwater storage system

The QuadroControl ST-B system shaft is designed to seamlessly integrate into modular block structures measuring 0.80 meters in both length and width. It serves multiple functions, including as an inspection shaft or ventilation point for the system, particularly effective when equipped with shaft covers featuring ventilation openings.

The assembly includes half elements that can be effortlessly installed on-site. For a full block shaft setup, a cone is utilized, while a roof slab is employed for a half block shaft configuration. The inclusion of a sidewall grid varies based on its placement within the storage or infiltration module, ensuring optimal functionality for different applications.

Rigofill ST modules are efficiently delivered stacked on pallets measuring 1.60 meters by 0.80 meters. Each pallet contains 68 half elements, sufficient for assembling 34 modules. Typically, the factory stacks two pallets on top of each other for shipment.

In addition to the main modules, sidewall grids, supporting grids, and roof slabs (required for half blocks) are packaged separately on individual pallets. This packaging approach ensures organized delivery and facilitates efficient on-site assembly of the Rigofill ST modules.

EN 17152-1 introduces the first-ever product standard for storage and infiltration modules across Europe, marking its inception in November 2019. This milestone was accompanied by the establishment of test standards for both short-term compressive strength (EN 17150) and long-term compressive strength (EN 17151).

This development is significant as it allows for the evaluation and comparison of long-term compressive strength using a standardized European test methodology for the first time.

Over time, it is anticipated that this standard will gradually replace national approvals or serve as the foundational framework for test requirements in obtaining regulatory approvals across European countries.

Rigofill storage and infiltration systems provide exceptional design flexibility, featuring minimal constraints on length and width. The square 800 mm block layout facilitates seamless adaptation to virtually any configuration. With block heights of 660 mm for full blocks and 350 mm for half blocks, these systems can be constructed in various sizes to accommodate both single-layer and multiple-layer configurations.

This adaptability allows for easy customization to meet specific on-site requirements. In areas with high groundwater levels or low permeability soil, shallow-depth systems are preferred for effective water management.

Conversely, in soils with good permeability, taller and denser systems offer advantages and can be constructed accordingly. This approach ensures maximum utilization of available space while meeting the project’s stormwater management needs effectively.

CCTV inspection using advanced technology is the optimal method for assessing the condition of systems like Rigofill ST modules. This approach allows for thorough examination during final acceptance or subsequent evaluations, ensuring confidence and safety for authorities, engineers, construction firms, customers, and operators.

Rigofill ST modules are equipped with a cross-shaped tunnel design, which enhances camera accessibility and facilitates flushability in two axes. This unique feature enables comprehensive inspection and maintenance in four dimensions, ensuring all aspects of the system are thoroughly examined and maintained as needed.
