3 large sets of Trench Shoring Steel Shields according to Krings International France (KIF):

Trench Box :

2 steel prefabricated panels with 4 spindles or struts. The spindles are hinged and sprung where they connect to the side panels, allowing an independent movement of each other. The installation of this box in the trench is either done progressively (the trench walls are supported at all time) with the excavator bucket, or after the digging, depending on the soil conditions; in that case 6 meters deep can be reached.

For removal, the trench box is pulled out, as the trench is backfilled.

Sliding and Lining Systems :

Ideal to use in poor soil conditions, this "dig and push" system allows low vibration installations, provides soil support for the excavations, adjacent structures and existing services or utilities, and minimizes trench width. This system is installed from the top down and removed from the bottom up.

Minimum restoration time and cost.

There are 3 types of sliding frames.

Sheet Piles :

These steel sections are cold rolled and their thickness varies from 3 to 8mm. Some special KD lapping sheet piles can be used with the Krings guiding frames KKP.
