The structural shape of the drainage board is that the plane of the plastic sheet is covered with regular plastic boards arranged vertically and horizontally. When in use, a layer of geonet is laid on it to play a supporting role. The geonet Spread a layer of geotextile on the surface, [3] plays a filtering role. In this way, a space of a certain height is formed between the geotextile and the plastic plate of the drainage board. The ground space is the air layer and the drainage layer. It has a certain support stiffness and three-dimensional drainage space. When it is used for drainage in the soil, the channel area will not be significantly reduced due to pressure or the non-woven fabric will be significantly intruded into the channel. 【3】It can make liquid and gas flow in the overhead layer between the bosses and be discharged quickly. After being spliced and laid by hot melt welding method, drainage and exhaust channels are formed, integrating waterproofing, drainage and protection.
Drainage boards are laid on planting roofs, roofs, and balconies to form an effective overhead layer for drainage. They also have the function of thermal insulation. [3] In order to ensure the effective drainage space of the drainage board, the drainage board must be combined with the geotextile (non-woven fabric) used together. The drainage principles of the two drainage boards are basically the same. The main difference is that the drainage board has a strong water storage function and a weak root separation function, while the drainage board has a strong root separation function and a weak water storage function.
Drainage board construction specifications
Please store drainage boards in a dry and ventilated environment, prevent exposure to the sun, and keep away from fire sources.
Please place the drainage protection board vertically or flatly. Do not tilt or cross-press it. The stacking height should not exceed 3 layers and avoid stacking of heavy objects. 【3】
When laying, it should be smooth and natural, and should be laid along the slope or according to the direction of the water flow.
When paving geotextile alone, ensure that the overlap joints are compacted with glue or sand to avoid movement, and then backfilled. The first layer of backfill soil must be compacted before proceeding to the next step. The layered backfill must be compacted. .
When using the drainage consolidation method to reinforce deep soft soil foundations, the use of drainage slabs is almost the only economical, effective and feasible method from technical and economic considerations.
