Disposable curb inlet drain form

摘要

A disposable form for manufacturing curb inlet drains in situ includes a base for forming the main body of the curb inlet drain, and a neck for forming a manhole opening. The base is made of a frangible material that can be broken into pieces and removed from the drain after concrete is poured and sets around the form. In other embodiments, both the neck and base are made of a frangible material. The form is lightweight, inexpensive, and reduces the cost of manufacturing curb inlet drains in situ.
