3. The excavation support system of claim 1 , wherein the corner roller cart comprises a generally vertical back plate having a front surface and a back surface, wherein the at least one roller is attached to the back plate, extending from the back surface thereof.

4. The excavation support system of claim 1 , wherein the two substantially parallel recessed grooves formed in the longitudinal axis of the corner slide-rail post define an approximate 90-degree angle therebetween.

5. The excavation support system of claim 1 , wherein each linear slide-rail post further comprises an extended faceplate disposed along the longitudinal axis thereof.

6. The excavation support system of claim 5 , wherein the corner roller cart further comprises a plurality of guide plates, wherein the guide plates are configured to slide onto and secure to the extended faceplate of the linear slide-rail post, and wherein the guide plates are configured to facilitate slideable movement of the corner slide cart in an upward and downward direction relative to the vertical axis of the linear slide-rail post.

7. The excavation support system of claim 1 , wherein the corner slide-rail posts further comprise an extended faceplate disposed along the longitudinal axis thereof.

8. The excavation system of claim 7 , wherein the corner roller cart further comprises a plurality of guide plates, wherein the guide plates are configured to slide onto and secure to the extended faceplate of the corner slide-rail post, and wherein the guide posts are configured to facilitate slideable movement of the corner slide cart in an upward and downward direction relative to the vertical axis of the corner slide-rail post.

9. The excavation system of claim 1 , wherein the corner roller cart further comprises a corner swivel brace, wherein the corner swivel braces comprises a generally vertical support configured to connect ends of two hydraulic brace legs, forming an angle therebetween.

10. The excavation system of claim 9 , wherein the generally vertical support is a generally vertical teardrop support.

11. The excavation system of claim 9 , wherein the angle between the two hydraulic brace legs is about 90-degrees.

12. The excavation system of claim 1 , wherein the corner roller cart further comprises a linking tube, wherein the linking tube is configured to connect two corner roller carts to one another when vertically aligned.

13. The excavation system of claim 1 , wherein the linear roller cart further comprises a linking tube, wherein the linking tube is configured to connect two linear roller carts to one another when vertically aligned.

14. A method for installing an excavation support system, comprising:

assembling a base structure in a pre-excavation trench, wherein the base structure comprises: a plurality of linear slide-rail posts, each linear slide-rail post having at least one recessed groove formed in a longitudinal axis thereof; a plurality of corner slide-rail posts, each corner slide rail post having two substantially parallel recessed grooves formed in a longitudinal axis thereof, wherein the two substantially parallel recessed grooves define an angle therebetween; a plurality of slide-rail panels having opposing first and second ends, wherein the first end is disposed within one of the recessed grooves of the linear slide-rail posts and the second end is disposed within one of the recessed grooves of the corner slide-rail posts;

disposing at least one linear roller cart, having at least one roller attached thereto, onto at least one of the plurality of linear slide-rail posts, wherein the at least one linear roller cart is 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, wherein the linear roller cart is movable in an upward and downward direction relative to the vertical axis of the linear slide-rail; and

disposing at least one corner roller cart, having at least one roller attached thereto, onto at least one of the plurality of corner slide-rail posts, wherein the at least one corner roller cart is adapted to slide onto the corner slide-rail post and secure thereto, the corner roller cart comprising a generally horizontal plate for supporting at least one hydraulic brace leg, wherein each corner roller cart is movable in an upward and downward direction relative to the vertical axis of the corner slide-rail post.

15. The method of claim 14 , further comprising disposing a wale beam onto each of the at least one linear roller carts disposed onto each of the plurality of linear slide-rail posts.

16. The method of claim 15 , further comprising securing a plurality of corner connections of the hydraulic brace legs, wherein each corner connection forms an approximate 90-degree angle.

17. The method of claim 16 , further comprising securing a plurality of knee brace or crossing brace connections, wherein each knee brace or crossing brace is disposed in a generally diagonal orientation proximate each hydraulic brace leg corner connection.

18. The method of claim 17 , further comprising connecting a generally vertical linking tube to each linear roller cart, wherein the linking tube is configured to vertically connect each linear roller cart to an additional linear roller cart, and wherein the linking tube has a top end and a bottom end.
