Abstract: A sub-soil injection device injects a soil additive, such as a pesticide, as included in a foam below the surface of soil. It concurrently distributes the foam into soil as the foam is injected resulting in an improved uniformity of distribution of soil additive in soil. The device comprises a tubular structure which mounts into the soil from a vehicle. It has first and second portions, leading and trailing portions, a lumen along its length, lateral portions and a plurality of spaced apart ports. Each port communicates the lumen with the trailing portion. Foam flowing out the ports moves backwardly. A shank structure precedes and shields the leading portion of the member. The shank structure has a forward-facing portion adapted to cut through soil. The shank structure and member are motivated by the vehicle in a forward direction through the soil. An apparatus utilizing the shank structure, the vehicle and a foam generator and a method of depositing a soil additive plowing in of foam are also set forth.

Abstract: A retaining wall has at least two facing panels in a tier adjacently interconnected by at least a pair of panel interconnectors mounted to the inner surfaces of the panels to allow adjacent panels to rotate relative to each other. Horizontal flexible anchoring devices, which include rigid anchors flexibly or rigidly connected to the panel interconnectors, connect the facing panels to an earth mass. The panels may tilt, or horizontally deform, relative to deformations in the earth mass. Front horizontal panel adjustment devices allow the tension of the connection between the flexible anchoring devices and the panel interconnectors to be varied from the front of the wall to allow horizontal alignment of the panels after the earth wall has been built. An adjustable inner panel supports the facing panels prior to the start of earth wall construction. Geofabric layers, independent of the flexible anchoring, are used during construction to stabilize the earth wall.

Abstract: A trench is excavated from the top surface of an earthen dike, all the way down into the foundation below the base of the dike. Dry powder, partially hydrolyzed polyacrylamide (PHPA) is mixed with fresh water and soda ash in proportions of 20 lbs PHPA, to 4 lbs of soda ash, to 68 barrels of fresh water (2856 gallons) to form a slurry having a funnel viscosity of at least 45 sec/quart. As the trench is being excavated, the slurry is pumped into the trench immediately. A section of geo-membrane having a thickness of 0.080" is placed in the trench all the way to the bottom of the trench, overlapping at the top of the membrane onto the top surface of the dike. Dry sand is then pumped into the trench to displace the slurry in the trench.
