Lid construction
The lid construction method was first used in underground railway construction. There, the lids were used to maintain road traffic in the construction site area and to be able to excavate and continue construction under the lid. The lids were also used to brace the excavation pits.
Lid construction
In recent years, the cover construction method has been increasingly used to brace large excavation pits. The construction time for building construction sites can be shortened by this technique; here, after the construction of the cover, simultaneous construction upwards and downwards is possible.
