Abstract
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.
Claims17
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.
A method of providing a double door damper system for storm water conveyance structures, comprising the steps of:
- providing a first door with side edges slidable within first tracks in a first frame about a passage through a water conveyance opening;
- providing the first door with a first opening therethrough for defining a smaller passage than the passage through the water conveyance opening;
- providing a secondary door with side edges slidable within second tracks of a second frame on the first door;
- providing a vertical bar member rotatably mounted to at least one bar mount adjacent to the side edges of the second door;
- providing a plurality of spaced apart moveable members along the vertical bar member;
- pushing the secondary door against an interior portion inside the second tracks by rotating the vertical bar member;
- and
- rotating the moveable members in a horizontal axis from a loose position where the secondary door is loosely seated in the second tracks to a closed position where the secondary door is pushed against the interior portion of the second tracks;
- and
- locking the secondary door to different height position for adjusting size of the passage through the water conveyance opening.
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;
- providing a second door having a length and width that is substantially sized to close off the opening through the first door;
- attaching rotatable wheels to outer edges of at least one of the first door and the second door, the wheels having a retracted loose position and an extended wedge position;
- rotating the wheels in the retracted loose position for sliding the at least one of the first door and the second door;
- and
- moving the wheels to the extended wedge position to prevent the at least one of the first door and the second door from sliding up and down.
