The invention provides a horizontal drainage board structure and a construction process. The horizontal drainage board structure comprises multiple groups of drainage bodies, wherein each group of drainage bodies comprises two vertical pipes which are vertically inserted into mud and at least one drainage board for communicating the two vertical pipes; the bottom end of each vertical pipe is sealed; the upper end of each vertical pipe extends out of the mud surface; upper ends of all the vertical pipes are communicated by a horizontal pipe set; a membrane outlet is formed in the horizontal pipe set and is communicated with vacuumizing equipment. According to the horizontal drainage board structure and the construction process, the drainage bodies for connecting multiple groups of vertical pipes with the drainage boards are inserted into a reinforcing area of dredging soil, so that the soil body reinforcing effect of reinforcing a soft soil foundation by adopting a vacuum preloading method is improved, and the problem that the existing drainage boards adopting the vacuum preloading method easily deform and are poor in reinforcing effect are solved.
Description
technical field [0001] The invention relates to a horizontal drainage plate structure. [0002] The invention also relates to a construction technique of the horizontal drainage plate structure. Background technique [0003] In recent years, with the rapid development of my country's economy, dredging land reclamation projects in coastal areas are increasing; however, due to the lack of sand and gravel resources in these areas, silt dredged from channel dredging is often used as dredging land reclamation materials. This kind of soft soil has low strength, high water content, poor permeability, and high compressibility. Engineering construction on this foundation will bring many problems: First, due to the low permeability and high compressibility of soft soil, if the Engineering construction on this type of foundation will cause large settlement and uneven settlement, and the settlement time is relatively long; second, due to the low strength of soft soil, the stability and...
