ABSTRACT:
A trench forming assembly and removable form for forming a trench of predetermined shape is disclosed according to the present invention. The removable form includes an elongate form body having top, bottom and opposed side surfaces and first and second elongate form removal slots extending upwardly from the bottom surface of the form body. Preferably the removable form has a top surface defining a complex shape including at least a first upwardly extending ear portion which extends longitudinally along the top surface. At least a first form removal slot of this elongate form body extends into a portion of the first ear portion. Advantageously, the form body includes a pair of coplanar elongate slots integrally formed in the side surfaces for receiving a pair of frame members in a predetermined coplanar, spaced relationship above the bottom surface of the form body. In another embodiment, a removable form includes a second elongate form body portion extending laterally along one side surface of the elongate form body and having a predetermined shape for forming a structure having a corresponding shape, such as a curb.
