Abstract
A filtration apparatus for curb vaults may be installed in existing vaults through manhole access openings whenever the smallest dimension of the access opening is greater than the smallest dimension measured across a support plate assembly of the filtration apparatus. An adjustable attachment system allows installation of the filtration apparatus by inserting the apparatus through the access opening.
Claims13
A filtration apparatus for a run-off vault having a vault interior defined by opposed interior walls, and a manhole opening into the vault interior, the improvement comprising:
- a generally planar support plate that defines a surface onto which run-off flows when said run-off enters said run-off vault, said support plate having an opening therethrough and a linear edge that defines a support plate width having a first dimension and a non-linear edge that defines a support plate depth having a second dimension, where the first dimension is greater than the second dimension;
- at least one leadscrew attached to the support plate, the leadscrew comprising a rod adjustably attached to the support plate so that the rod may be selectively extended from and retracted relative to said support plate,
- a filter in fluid communication with the opening;
- wherein said manhole opening defines a third dimension that is greater than the second dimension but less that the first dimension and wherein the support plate and the at least one leadscrew are inserted into the vault interior through the manhole opening and said support plate is supported in a substantially horizontal orientation in said vault interior only with the at least one leadscrew.
A filtration apparatus for a run-off vault having opposed first and second interior walls that define a vault interior therebetween and a manhole access opening having a manhole access dimension and curb inlet opening into the vault interior, the improvement comprising:
- a support plate having a width defining a first dimension and a depth defining a second dimension, where the first dimension is greater than the second dimension and the second dimension is less that the manhole access dimension so that the support plate is insertable through the manhole access opening into the vault interior for supporting a filter assembly in the vault interior between first and second opposed interior walls of the vault, said support plate defining a run-off carrying surface onto which run-off flows when run-off enters said vault;
- a pair of leadscrew assemblies attached to the support plate, each leadscrew assembling comprising a sleeve adapted for adjustably receiving a rod so that said rod may be selectively extended from and retracted into said sleeve, and each rod having a distal end adapted for bearing against the first interior wall of the run-off vault, and each sleeve having an end adapted for bearing against the second interior wall of the run-off vault;
- wherein said support plate is supported in a horizontal position in said vault interior only with said pair of leadscrew assemblies.
