Unformatted text preview: Pile Cap Retaining Walls Design Factors include: :height, surrounding Soils, Surrounding Water, Surrounding Structures. Design Failures include: cracking, overturning, lateral sliding, undermining. T-Type Gravity L-Type Control Joint Expansion Joint Waterproofing Damproofing Drain Pipes Backfill Drainage Tile Tremie An excavation is created and held open with a slurry (clay/water mix). A "tremie" pipe (open pipe) is lowered to the bottom of the excavation. Concrete is placed into the pipe and allowed to drop through the pipe to the bottom of the excavation. The concrete begins to form a pile at the bottom, displacing the slurry out of the excavation. The pipe (tremie pipe) is raised slowly allowing the excavation to be filled with concrete. This process is used for the slurry wall panels, for secant piles, and for the bottom slab ("plug") at each shaft. The bottom slab is a "plug" designed to prevent water from entering into the shaft from the bottom....

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
