发明名称 Modular curb and sewer casting form
摘要 A multi-section form for casting sewer inlet ports to manhole standpipes with right, left or bi-winged curb sections. The form includes multiple sections which can be arranged to segregate the form interior to cast inlets with a preferred arrangement of one or more curb extension wings. Pre-assembled rebar and manhole port assemblies mount within the arranged form sections, along with a multi-section form which defines a top cover and inlets to a center manhole port. An extension form wall at the manhole port assembly defines an overflow conduit. The casting form is supported to a low profile casting table which defines a bottom form wall and includes a hydraulic lift for tilting the table top to eject a cast part.
