ADS FLEXSTORM CONNECTOR PIPE SCREEN (CPS) WORK INSTRUCTIONS

Transcription

1 ADS FLEXSTORM ONNETOR PIPE SREEN (PS) WORK INSTRUTIONS 1.0 Product Selection: Installer to determine which PS Model is required based on LA ounty s APPENDIX B PS SIZING TABLE (Tables 1 and 2) revised 5/20/2015. The Screen Length, Screen Height, and Bypass Height (when required) are established from the tables, but the ADS Screen Shape will depend on particular location of the connector pipe and manhole entry. Refer to ADS FLEXSTORM PS SELETION GUIDE to determine base model numbers and shapes. 2.0 Materials: All FLEXSTORM PS are comprised entirely of 304 stainless steel and brought to the field pre-configured for easy assembly once Product Selection is confirmed; All Models are supplied with vertical upright mounting brackets which accept qty (4) 3/8 x 3 minimum stainless anchor bolts. All bypass lids require a qty (2) 3/8 x 3 min stainless anchor bolts. Mounting brackets are equipped with slotted holes to allow for varied contours on walls and sloped floors. 3.0 Installation of Base Model: Drop PS through the manhole opening. Position the PS evenly spaced around the connector pipe ensuring a minimum of 4 spacing away from any corners. Loosen the bolts in the slotted holes which connect the screen to the upright mounting brackets until the bottom is flush with the floor. Tighten the bolts and mark the hole locations on the wall for the stainless anchor bolts. Drill holes and hammer the bolts in place and secure the PS using stainless nuts. If the bottom of the base exposes more than a 5 mm gap then an additional base face strip may be fastened to the base channel using corrosion resistant screws or rivets. This base face strip matches the length of the PS and will need to be scribed and custom cut to match the contour of the floor. 3.1 Installation of Bypass Lid: If the bypass lid is required verify the minimum bypass height needed and mark the B bypass height location on the wall directly above the base uprights. Lift the lid in place and mark the hole locations for the lid mounting brackets. Drill holes and hammer the bolts in place and secure the lid with the stainless nuts. 4.0 Quick Release PS Options: In certain locations, the PS may need to be removed quickly in order to provide increased accessibility through the manhole entry. In such cases, the PS would utilize the Quick Release wall mount bracket set and standard PS flanges. See the installation drawing labeled Quick Release PS Detail for step by step instructions. In standard installations, the PS can be removed by simply loosening the 3/8 anchor nuts that secure it to the wall. Warranty: ADS FLEXSTORM warrants the PS material to be free of defects and guarantees base framing integrity for a period of 3 years from installation date.

2 ADS FLEXSTORM ONNETOR PIPE SREEN (PS) MAINTENANE GUIDELINES FLEXSTORM suggests that its onnector Pipe Screens (PS) be maintained per this modified set of conditions from the LA ounty PS Standards. FLEXSTORM advises that catch basins be cleaned out at least 2 times per year and/or if debris has filled above a 40% level inside of the catch basin. Sites with large amounts of foliage, high sediment loads, or smaller PS devices might need to be cleaned more frequently. Maintenance onditions and Maintenance Standards: The Following are deficiencies in maintenance conditions and their corresponding maintenance standards which shall apply to the onnector Pipe Screen. The cleanout of each B shall meet the maintenance standards listed as follows: Description of Maintenance Actions 1 lear trash and debris located immediately in front of curb opening or side opening of B, and on top or between metal grates of grated B. 2 Remove Vegetation growing across and/or blocking the basin opening. 3 Remove all Trash and debris and vegetation from inside the atch Basin Remove Trash and debris in the connector pipe opening, upstream or downstream. Knock off/remove all Debris that covers the perforated openings of the connector pipe screen Ensure there is no Standing Water inside of catch basin (indicates the device is not properly draining) Trash and debris shall include, but is not limited to, mud, vegetation, and garbage. Upon completion of a cleanout operation at a B and before leaving it, the ontractor shall sweep the top surface of the B and the area 2 feet around the B, and shall remove any trash and debris resulting from the cleanout operations. No debris is to be left at a B for future pick-up. Method of Removal: All trash and debris required to be removed from the Bs shall be removed in a manner to be determined by the ontractor. This can be done by hand or with a truck mounted vacuum. If entering the catch basin ensure that local confined space entry procedures are followed. The ontractor shall not allow any trash or debris to enter the connector pipe or main line as a result of the cleanout operations. Debris Disposal: All trash and debris removed under this ontract shall become the property of the ontractor and shall be legally disposed of away from the B sites. The ontractor is responsible for proper disposal of the trash and debris, including obtaining approvals from all jurisdictional agencies, as applicable. The contractor shall be responsible for contacting and coordinating with local Animal are and ontrol for pickup and disposal of dead animals. However, the ontractor shall be responsible for removing any dead animal from inside a B.
