A slurry wall is a civil engineering technique used to build reinforced concrete walls in areas of soft earth close to open water, or with a high groundwater table. [1] This technique is typically used to build diaphragm (water-blocking) walls surrounding tunnels and open cuts, and to lay foundations. Slurry walls are used at Superfund sites to ...
The solution employed by Yamasaki and his team of engineers was to use a slurry wall; digging very narrow trenches about 3 feet (0.91 m) wide and then filling these with a slurry (a mixture of clay and water) that was dense enough to keep the surrounding water out. Pipes were then lowered into the slurry trench and concrete was pumped in.
When the trench was dug out, a steel cage was inserted and concrete was poured in, forcing the slurry out. The slurry method was devised by Port Authority chief engineer John M. Kyle Jr. Towards the end of 1966, work began on building the slurry wall, led by Montreal-based Icanda, a subsidiary of an Italian engineering firm, Impresa Costruzioni ...
A road being resurfaced using a road roller. Red surfacing for a bicycle lane in the Netherlands. Construction crew laying down asphalt over fiber-optic trench, in New York City. A road surface (British English) or pavement (North American English) is the durable surface material laid down on an area intended to sustain vehicular or foot ...
The trench is then carefully back-filled and the surface is reinstated. Top-down method: Side support walls and capping beams are constructed from ground level by such methods as slurry walling or contiguous bored piling. Then a shallow excavation allows making the tunnel roof of precast beams or in situ concrete.
Cellular confinement systems (CCS)—also known as geocells —are widely used in construction for erosion control, soil stabilization on flat ground and steep slopes, channel protection, and structural reinforcement for load support and earth retention. [1] Typical cellular confinement systems are geosynthetics made with ultrasonically welded ...
Tiebacks to reinforce a slurry wall at Ground Zero, New York. A tieback is a structural element installed in soil or rock to transfer applied tensile load into the ground. . Typically in the form of a horizontal wire or rod, or a helical anchor, a tieback is commonly used along with other retaining systems (e.g. soldier piles, sheet piles, secant and tangent walls) to provide additional ...
Bentonite slurry walls (also known as diaphragm walls [43]) are used in construction, where the slurry wall is a trench filled with a thick colloidal mixture of bentonite and water. [44] A trench that would collapse due to the hydraulic pressure in the surrounding soil does not collapse as the slurry balances the hydraulic pressure.
