A system and method for widening a highway and supporting a sound wall is provided that includes a single row of caissons for providing the sole foundation of a breast wall and a sound wall. The caissons include a vertically-oriented network of reinforcing steel, an upper portion of which is integrated into the steel reinforcing network of a cast-in-place breast wall. The sound wall is mounted on and supported by the top ends of the caissons and serves to obstruct the transmission of sound from the highway. The vertically-oriented reinforcing members of the caissons are spaced away from the center portion of each caisson in two opposing groups in order to maximize its bending strength in a direction orthogonal to the highway, which is the primary direction in which cut earth, compacted fill material, and winds apply bending moments to the breast wall and sound wall. The use of a single row of caissons having a high bending strength in a direction orthogonal to the highway minimizes the labor and materials necessary to support the breast wall and the sound wall, and advantageously minimizes the amount of space necessary to excavate and construct the foundation.

A system and method for adjustably connecting traffic barriers and pre-cast wall facing panels to the soldier beams of a pile wall is provided, which includes a connecting structure cast-in-place between the upper ends of the beam and the panels for structurally interconnecting both a traffic barrier and the upper ends of the panels to the beam. The system further includes an anchor member projecting from the upper end of the soldier beam for securing the connecting structure to the beam, as well as a depth-adjustable array of reinforcing members that are cast within the structure for accommodating variations in the distances between the beams and panels. At least one of the array of reinforcing members projects upwardly out of the connecting structure to link the traffic barrier to the connecting structure. In the method of the invention, the connecting structure is cast-in-place on top of a connecting column that secures the wall panels to the soldier beams, and the traffic barrier is in turn cast over the connecting structure after it sets.

A system and method for widening a highway and supporting a sound wall is provided that includes a single row of caissons for providing the sole foundation of a breast wall and a sound, wall. The caissons include a vertically-oriented network of reinforcing steel, an upper portion of which is integrated into the steel reinforcing network of a cast-in-place breast wall. The sound wall is mounted on and supported by the top ends of the caissons and serves to obstruct the transmission of sound from the highway. The vertically-oriented reinforcing members of the caissons are spaced away from the center portion of each caisson in two opposing groups in order to maximize its bending strength in a direction orthogonal to the highway, which is the primary direction in which cut earth, compacted fill material, and winds apply bending moments to the breast wall and sound wall. The use of a single row of caissons having a high bending strength in a direction orthogonal to the highway minimizes the labor and materials necessary to support the breast wall and the sound wall, and advantageously minimizes the amount of space necessary to excavate and construct the foundation.

A system and method for adjustably connecting pre-cast wall facing panels to the soldier beams of a tie-back or anchor wall is provided, wherein the system comprises an array of panels stacked in rows having mutually adjacent side edge portions which are spaced apart from one of the soldier beams, a connecting column cast-in-place between the beam and the adjacent side edge portions of the panels for structurally interconnecting both of the panels to the beam, and an adjustable array of reinforcing members within the column for interconnecting the adjacent side edge portions of each of the panels with the beam and for reinforcing the resulting column. The depth of the cast-in-place connecting column advantageously accommodates variations in the distances between the beams and panels. In the method of the invention, a first row of wall facing panels is stacked in front of the soldier beams, and a first section of the connecting column is cast therebetween. Thereafter, a second row of panels is stacked on top of the first, and the process repeated until the wall achieves its desired height. Both the system and the method are particularly applicable to tie-back walls employing piles since the cast-in-place connecting column automatically adjusts for misalignments between the piles and the wall facing panels.
