Mesquite Street By-Pass Stormwater

Client:
Main Contractor: J.J. Fox Construction, Inc.

Project Specification:

The purpose of the project was to mitigate flooding in the area by improving drainage conveyance toward the Gulf of Mexico. The project required a combination of single and double barrel runs of triple wall 60” HDPE pipe in order to provide additional drainage capacity for the town of Rockport.

Solution:

Based on an engineered required load of up to 11,000 lbs per location, Platipus offered both 2 ton and 10 ton capacity anchor solutions, depending on the required loads in a particular area. The soil was a dense, well-compacted sand which allowed for high loads to be achieved. Approximately 270 pipe anchoring kits, or 540 anchors, were supplied over a 3-mile long drainage line. The anchors were installed with a traditional jack hammer. Each anchor was loadlocked and the load was recorded in order to field verify that the design load was achieved on-site. The ability to field-verify loads, in addition to the small amount of equipment required to install, allowed the Platipus system to be selected in lieu of a combination of poured concrete footings and stainless steel strapping mechanisms.
