Topic: Dewatering: A Case Study in Excavations through Sands Below the Groundwater Table. LANDIR Hydro Impact Basin; NASA Langley Research Center. Hampton, Virginia.
This project consisted of the construction of a Hydro Impact Basin located at the west end of Langley's historic NASA Landing and Impact Research Facility, also known as the Gantry, where Neil Armstrong trained for walking on the moon. Project comprises the construction of 115 feet by 85 feet and 20 feet deep pond. Three sides of the pond will have slopes of 1.5H:1.0V and one side will be vertical supported by a bulkhead 60 foot long. The purpose of the structure will serve to validate and certify that future space vehicles, such as NASA's Orion crew module, are designed for safe water landings. Main tasks were: (1) conducted a subsurface exploration, drilled soil borings to investigate subsoil conditions, (2) conducted a pumping test and two constant head permeability tests to investigate the soil permeability, (3) designed a100-foot deep eductor dewatering system to lower the groundwater table to 25 feet below the existing ground surface, and (4) analyzed the temporary excavation slope and provided an excavation plan for the impact pond structure to assure its stability.
