Construction Operations and Quality Control of Deep Mixing at Levee LPV111 New Orleans
Deep Mixing (DMM) for the LPV-111 Levee in New Orleans presented many Quality Control and logistical challenges. The project consists of approximately 1.4 million cubic meters (1.7 million cubic yards) of Deep Mixing to a depth of up to 20.5 meters (67 feet), consisting of over 17,000 elements. Eight deep mixing rigs were utilized: three double axis Trevi Turbo Mix rigs (TTM), two single axis TTM rigs, and three double axis CI-CMC rigs. Eight batch plants were used to prepare the grout using over 417,000 tons (460,000 short tons) of slag/cement binder. The work was accomplished within an aggressive schedule by working 24 hours per day, 5.5 days per week. The US Army Corps of Engineers (USACE), using the early contractor involvement (ECI) process, developed a stringent set of specifications in order to ensure a quality product was installed. The drill rigs were equipped with innovative electronic control and logging devices in order to record all pertinent parameters of each element, as well as many other different functions described in this paper. Quality Control of the installation process was continually monitored by examining these records, monitoring the grout produced at each batch plant, and coring over 10,000 linear meters (34,000 feet) of three inch and four inch diameter core. The USACE implemented an extensive Quality Assurance program to monitor the entire deep mixing process, which included independent testing to confirm the Quality Control test results. This paper describes the materials, equipment, methods of construction, and Quality Control procedures that were applied to overcome the tremendous technical and logistical challenges to successfully complete this project.
