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 .
The hydromill trench cutter is a specialized type of construction equipment designed to dig the narrow but deep trenches used in the casting of slurry walls. Typically, it is a cutter attachment mounted on a crawler crane base machine, with different types of hose handling systems.
The use of slurry walls is well-established in the construction industry. The application of (low) pressure grouting , used to mitigate soil liquefaction risks in San Francisco and other earthquake zones, [ 2 ] has achieved mixed results in field tests to create barriers, and site-specific results depend upon many variable conditions that can ...
The anti-tunnel barrier along the Gaza–Israel border (sometimes referred to as the smart wall on the Israel–Gaza border) [1] [2] [3] is an underground slurry wall constructed by Israel along the entire 40-kilometer (25 mi) length of the Gaza–Israel border to prevent infiltration into Israel by digging tunnels under the Gaza–Israel barrier.
Tiebacks to reinforce a slurry wall at Ground Zero, New York. In geotechnical engineering, a tieback is a structural element installed in soil or rock to transfer applied tensile load into the ground.
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.
The design and construction of the World Trade Center, most centrally its twin towers, involved many other innovative techniques, such as the slurry wall for digging the foundation, and wind tunnel experiments. Construction of the World Trade Center's North Tower began in August 1968, and the South Tower in 1969.
1969 view of the original WTC bathtub looking northwest. Note PATH eastbound tunnel F supported on a temporary trestle in foreground. Slurry wall with tie-backs can be seen on the left, and the frame of the north tower in the background. Also note the since-removed elevated west-side highway, which ran above West Street (today's West Side Highway).
