Interlayer Isolation of Wide Horizontal Integral High-performance Drainage Boards/Reinforcement/Drainage Application
1、Application in horizontal diversion drainage engineering
The 1.5m-wide horizontal drainage board is a high-performance drainage material with multiple functions, of which the strength and the isolation and anti-filtration performance are stronger than those of geotextile, the strength is stronger than that of plastic geogrid, and the permeability, resistance, flow rate, compression strength, and deformation resistance are higher than those of sand cushions and filter tubes.。
(1) The 1.5m-wide horizontal integral drainage boards are cross- stacked and laid for the horizontal diversion drainage layer channels, which can replace the horizontal gravel drainage layer and filter tubes. The drainage boards are provided with integral diffusion-type vacuum collector drainage components so that the vacuum suction loss is reduced, the range of suction is increased, and the quantity and power consumption of vacuum pumps are reduced.
(2) The wide horizontal integral drainage boards, with multiple functions of horizontal diversion drainage, isolation, anti-filtration, and reinforcement, can be used in projects under different scenarios and operating conditions.
2 . Application in interlayer isolation and impermeability/reinforcement/drainage engineering
(1) The drainage boards are applied to the top surface of tunnels, road subgrades, slopes, plaza foundations, stadium track foundations, pedestrian walkway foundations, underground garages and garage roofs of housing construction, roofs of buildings, factory floors, and other works.
(2) The wide horizontal integral drainage boards are laid in the base
layer of buildings and the interlayer in the surface layer, playing
multiple roles, such as anti-filtration, isolation, seepage control, drainage, and reinforcement, and can resist damage to the surface
layer (such as hollowing and cracking) caused by wet swelling of the
base surface and uneven settlemnt of the foundation
