Analysis of the conventional vacuum preloading method
IOP Conference Series: Materials Science and Engineering, 2020 Abstract The conventional vacuum prepressing method is to reinforce the soft soil foundation. The process is to lay a certain height of horizontal sand cushion layer on the surface to form a horizontal drainage channel, and then set up a plastic drainage plate and connect it with a pumping pipe to form a vertical drainage channel.
