Abstract
PVC panels for a bulkhead are characterized by an elongated S-shaped cross section and an axial passage extending from top to bottom. The panels are joined by tenon in mortise joints, preferably via a spade shaped tenon. The assembly is capped with a channel to position and strengthen the upper ends of the panels. A stake positioned through the passage and into the earth also secures the panels. The panels are positioned by water flow through the passage during the sinking process. Soil stabilization chemicals can also be introduced through the passage. A nozzle for the lower end of the passage is also disclosed.
