Rotatable wheel box service panel door and equalizer and method

摘要

Systems, devices, apparatus, and methods of locking and unlocking a door that is slidable by articulating wheels in tracks, over an entry port to a storm water structure. Locking the door can be accomplished by rotating bolts that are attached to cams. Rotating the bolts causes the cams to press the door against the tracks. Sealing strips can be compressed between door edges and the track to prevent water from passing around the door. A vacuum truck can remove water and debris from the vault/structure. Other versions allow doors to move downward to allow water to overflow the door. The door can slide upward so water can flow underneath. A door in door version has a secondary door slide up and down in tracks in a main door.

主权项

1. A method of providing overflow and underflow conditions through a storm water passage, comprising the steps of:
providing a first door having a length and width that is substantially sized to close off a water passageway, the first door having an opening therethrough; attaching at least one member to sides of the first door, the at least one member having a loose position in the passageway to allow the first door to move up and down in the passageway, and a wedge position to prevent the first door from moving in the passageway; providing a second door having a length and width that is substantially sized to close off the opening through the first door; and adjusting the first door and the second door to alternatively allow for water to pass over and under a portion of the passageway.
