The wall is set at least partially below a surface, the surface either being land-based or aqueous-based, and interfaces therebetween, e.g., shoreline. The modules of the wall are fastened to each other by respective fastening mating fasteners. The retaining wall is installed by a process employing a fluid-assisted internal mandrel. ## Claims ### Claim 1 A process to install retaining wall modules, at least one module having a longitudinally open U-shaped channel disposed therein comprising the steps of: inserting a mandrel into the at least one module having the longitudinally open U-shaped channel, the mandrel having a mandrel length along its longitudinal axis greater than the module length along its longitudinal axis, the mandrel comprising: two opposed pairs of connected sides forming an enclosed longitudinal mandrel channel, the channel having a top portion and a bottom portion; a fluid conduit disposed within the mandrel channel, the fluid conduit having an inlet and an outlet; the top portion of the mandrel securely positioned on a top of at least one of the opposed pair of connected sides of the mandrel, the top portion having an upwardly-extending projection portion for releasable secured connection with a pair of jaws of a vibrator, the top portion having a pair of opposed downwardly-extending slots to permit insertion of a pair of opposed sides of the module, the top portion also containing a fluid inlet into the fluid conduit; the bottom portion of the mandrel securely positioned on a bottom of the at least one of the opposed pair of connected sides of the mandrel and having an egress opening for the fluid conduit at the bottom of the mandrel and positioned at an extremity of the mandrel beyond the module length of the open U-shaped channel along its longitudinal axis, the bottom portion of the mandrel extending beyond the longitudinal length of the U-shaped channel of the retaining wall module; affixing a source of at least one pressurized fluid to the fluid inlet of the top portion of the mandrel; affixing the vibrator to the upwardly-extending projection portion by engagement of the upwardly-extending projection with the pair of jaws of the vibrator; positioning the module for insertion into a location; ejecting pressurized fluid through the egress opening for the bottom portion of the fluid conduit while vibrating the mandrel to allow penetration of the U-shaped channel and mandrel into the location. ### Claim 2 (depends on 1) The process of claim 1 wherein the at least one pressurized fluid is selected from the group consisting of compressed gas and pressurized liquid. ### Claim 3 (depends on 2) The process of claim 2 wherein the compressed gas is air and the pressurized liquid is water. ### Claim 4 (depends on 1) The process of claim 1 wherein the fluid inlet into the fluid conduit is a 90° elbow. ### Claim 5 (depends on 1) The process of claim 1 wherein a pressure of the pressurized fluid is at least approximately 50 psig when the fluid is a gas, and wherein a pressure of the pressurized fluid is at least approximately 5 psig when the fluid is a liquid. ### Claim 6 (depends on 1) The process of claim 1 wherein the bottom portion of the mandrel is either beveled or tapered. ### Claim 7 (depends on 1) The process of claim 1 which further comprises the step of: filling each module with concrete. ### Claim 8 (depends on 1) The process of claim 1 wherein the step of positioning the module for insertion into a location comprises: adding at least one second module to a first module by sliding mating engagement of a male projection into a female receiving channel. ### Claim 9 (depends on 1) The process of claim 1 wherein the step of positioning the module for insertion into a location comprises: adding at least one third module to a second module by sliding mating engagement of a male projection into a female receiving channel. ### Claim 10 (depends on 1) The process of claim 1 which further comprises adding a pair of opposed and connected weep holes into at least one module to permit draining from an uphill ground location to a water location, the weep hole on the water side of the module positioned above a water line.
