Excavation in soil, for the installation of pipes, utilities, or manholes can be dangerous in poor or unstable soil and can cause unsafe working conditions for working crew said an expert from ICON JDS slide rail system company. A sliding rail system makes for a solution that can enable you to support the side-walls of pits or trenches at low costs. This system is an alternative to traditionally used sheeting and consists mainly of steel panels and vertical steel posts. The panels slide into the slots created on the posts. This method of installation is referred to as dig and push, as both the posts and panels are pushed into the pit or trench gradually while the required excavation is undertaken. As the depth of the excavation increases, the posts are pushed deeper along with the panels. This gradual installation eliminates any collapse of trench or pit walls. It is a system that is modular and allows for a variety of combinations and arrangements that make it a very versatile shoring system. While forming a pit, an initial pilot cut is made, and the first corner post and panel are put into the required position. Another corner post is installed so that a right angle is formed. The other two posts that make the corners of the pit are installed with panels. Panels will have two tracks on which they can be slid, one outside and one inside. As the excavation is made deeper, the posts are pushed further along with the panels installed, and the depth is made up with panels fitted on the inside track. Excavation is continued till the desired depth with panels being continually slid into place. Once the work of installation of pipes, manholes or other utility is completed, the inner panels are extracted and the pit is backfilled and compacted as required. As the backfilling proceeds, the posts and outer panel are extracted gradually, until the entire depth of the pit is filled. For use in trenches, a sliding rail system will require posts to be braced against each other, and here again, the sliding arrangments allow for struts or other propping arrangements to be put in place gradually as the trench is made deeper. The same sequence is followed while installing the posts and proceeding with the excavation. This type of shoring system requires a top-down installation and bottom-up removal that helps to minimize the size of the excavation and reduces soil disturbances to the minimum. Low vibration during installation is advantageous for adjacent structures and any other existing utilities.
