International Classification:

E02D 17/08

Abstract:

An excavation support system and methods for making same. The system can include a plurality of linear slide-rail posts; a plurality of corner slide-rail posts; at least one slide-rail panel having opposing first and second ends, wherein the first end is disposed within the recessed groove of the linear slide-rail post and the second end is disposed within one of the recessed grooves of the corner slide-rail posts; at least one linear roller cart, having at least one roller attached thereto, adapted to slide onto the linear slide-rail post and secure thereto, the linear roller cart comprising a generally horizontal plate for supporting at least one hydraulic brace leg; and at least one corner roller cart having at least one roller attached thereto, adapted to slide onto the corner slide-rail post and secure thereto. Each cart having a generally horizontal plate for supporting at least one hydraulic brace, and movable in an upward and downward direction relative to the vertical axis of the slide-rail post.

Abstract:

A roller cart and methods for installing in an excavation support system. The roller cart can include a generally vertical back plate having a front surface, a back surface, a top end, and a bottom end. A generally horizontal base plate, having a top side and a bottom side, can be attached to the back plate at about a 90-degree angle, proximate the bottom end of the back plate. A first side plate and a second side plate that are generally L-shaped, having a generally vertical top portion, and a bottom portion that is generally perpendicular to the top portion can be attached to and generally perpendicular to the back surface of the back plate. The bottom portion of both side plates can be attached to and generally perpendicular to the bottom side of the base plate. The first side plate and the second side plate can be generally parallel to one another. A first plurality of guide plates can be attached to, and generally perpendicular to, the generally vertical top portion of the first side plate, and a second plurality of guide plates can be attached to, and generally perpendicular to, the generally vertical top portion of the second side plate. At least one roller can be connected to the back plate and extending from the back surface thereof. The roller acts as a contact point and ball bearing to compensate for any angular deviations from the vertical and straight lines of the excavation structure. This significantly eases installation and removal, and greatly reduces the time to install and remove the cart.
