Bridges
Blind Headings
Constructing a tunnel is always a hard task, however, favorable the terrain and the equipment for it is… But sometimes this process forces us to perform the job without retrieving shields or TBMs. This is often the case when making live sewer connections or similar tasks.
Underground Structures Renovation:
Almost all types of technical and infrastructural underground structures require some degree of maintenance over time. Quite often it is far more viable to keep repairing the old system because constructing a new one will be much more expensive in the short-term perspective.
Renovation can be achieved by many methods including;
- Tunnel Relining
- Specialist Pressure and Annulus Grouting
- Tunnel Cleaning
- Shaft Relining
Archi CE has completed a multitude of underground renovation works throughout the last few years and we are capable of working around any underground structural requirements.
Drill & Blast
Drill and Blast is a specialist area in Civil and Mining operations and part of Archi’s features list is offering this service for shaft and tunnel construction, quarrying and underground mining works. When employing low-impact explosives and nonexplosive rock breaking technology we are much ahead of the competition, becoming more popular in sensitive areas. Over those years we’ve developed a solid experience in executing this type of work, including blast design, drilling, and shot firing.
Rock Support
Tunnels, shafts, mines and cuttings – all of these types of excavation tasks quite often require permanent or temporary maintenance when the rock face is exposed. Our experience in underground construction has enabled Archi to be able to provide one or a combination of various types of rock support.
