Our Pile Guide System with Corner connectors is a special solution for four- sided supported excavations with crossing service lines. The pile guide plates are equipped with special side adaption plates. The Corner connectors are similar to our Corner Slide Rails, e.g. having a special track for insertion of the side adaption plates. The Corner connectors have a height of 1.00 m.
The length of the pile guide plates is adapted to the length of the Slide Rail plates so that they can be combined. Plate length of 2.52 – 4.02 m has been proven in practice. As a result, the dimension of the four-sided supported excavation is ~ 3.20 – 4.70 m. The front end and the longitudinal plates can be different in lengths.
The Pile Guide System with Corner connectors is assembled and inserted as a complete unit into a pre-excavated trench of approx. 1 m depth. Then, the trench sheet piles type KD 6/8 are inserted into the special plate guides, which substantially facilitate sheet pile insertion.
The pile guide plates are the guiding frame for the trench sheets, as well as the upper support. At increased depth, it might be necessary to install further wailings and braces to improve rigidity.
When the manhole has been backfilled, the complete frame can either be moved into the next position, or the frame gets dismantled and the pile guide plates can be used in combination with our struts as standard Pile Guide Box. This system guarantees flexible use, short setup time and cost-effectiveness.
