Multi-arche

 

 

The Multi-arches® principle

Patented civil-engineering structures in the form of arches with the addition of prefabricated central supports, divided lengthwise and crosswise.

  • Span upon request
  • Backfilling height from 0.60 m to 25 m
  • Walls thickness from 180 mm to 350 mm
  • Computation of the interaction between ground and structure

Various types of Multi-arches®

Modular shapes according to the type of structure to be built, the environment,…

Advantages

 

Can be implemented while maintaining existing road traffic
Geometry modular according to the environment
Quick implementation
Improvement of hydraulic performance
(eliminating intermediate blocks of ballast)
Aesthetic lines
Economic and competitive solution
Quality control

The modularity of the Multi-arches® principle allows construction of:

Cut & cover tunnels
Road underpasses
Hydraulic structures
Hydraulic relief structures
