ABSTRACT:
A method and structure in which a Y- or V-shaped trench is dug in the ground for spatially receiving a smaller, complentarily shaped form that is supported in the trench by re-enforcing rods or the like that remain in the set-up concrete when the form is removed. The form has retractible side walls to facilitate removal from the finished trough and further includes removable gutter and drain means that are left as integral parts of the trough when the form is removed.
