The first residential building of slipform construction; erected in 1950 in Västertorp, Sweden, by AB Bygging Later picture of the residential building in Västertorp. Slip forming, continuous poured, continuously formed, or slipform construction is a construction method in which concrete is placed into a form that may be in continuous motion horizontally, or incrementally raised vertically.
The properties of a casting slip depends on multiple factors, including: [10] the properties of each raw material in the slip, the solids content of the slip, the clay:non-plastic ratio in the slip, the chemicals in the slip, either deliberately added or introduced from the raw materials and water, the type and amount of deflocculant,
The tremie concrete placement method uses a vertical or nearly vertical pipe, through which concrete is placed by gravity feed below water level. [4]The lower end of the pipe is kept immersed in fresh concrete so that concrete rising from the bottom displaces the water above it, thus limiting washing out of the cement content of the fresh concrete at the exposed upper surface.
Concrete used for canal lining is typically non-reinforced, as a way to reduce cost. A common method for constructing concrete lining is the use of slip forms, which are drawn down the length of the canal as the concrete is poured. [3] Hand laying of concrete or prefabricated sections are also used when only a short distance needs to be covered ...
Sliplining is a technique for repairing leaks or restoring structural stability to an existing pipeline.It involves installing a smaller, "carrier pipe" into a larger "host pipe", grouting the annular space between the two pipes, and sealing the ends.
