As an engineering office, we specialize in solving the specific challenges faced by our clients
in the energy and power sector. We provide comprehensive services ranging from technical
consultancy and design to the manufacturing of shoring and protection systems. Our
portfolio includes a wide array of standardized systemic solutions, and we also offer custom
design and production tailored to individual requirements.
We have successfully completed numerous energy sector projects involving the protection of
shallow, deep, narrow, and wide excavations. One of our recent assignments involved the
temporary shoring of a deep excavation for a power pylon foundation. This was achieved
using "Kopras" shoring technology in a box system with dimensions of 4.16 x 6.15 x 6.30 m.
The assembly consisted of:
- Four double-slide corner rails (6 m long each).
- Shoring plates measuring 4.16 x 2.40 m and 6.15 x 2.40 m.
- Top extensions with a height of 1.5 m.
The project design accounted for surcharge loads from heavy equipment traffic, loads from
soil embankments, and the positioning of a crane.
Deep Excavation Dimensions:
- Length: 6,15 m
- Width: 4,16 m
- Working depth: 6,30 m
