Supply Jiangsu plastic drainage board = impermeable membrane construction program * Price * Quality Contact [Li] (182 ~ 6481 ~ 7103) QQ: {46-37-96-887} look forward to sincere cooperation with you drainage board alias plastic drain , there are wavy, harmonica type shape. Drainage board is combined with the advantages of the foreign brands drainage board, according to the geological conditions in China developed more advanced soft ground and soft soil of new materials, with a single-hole cross section, drainage, light weight, tensile compressive strength characteristics. The middle of the drainage board extrusion plastic core, the drainage with skeletons and channel cross section was parallel on both sides of a non-woven geotextile wrapped as a filter layer, the core band play a supportive role and filter layer infiltrated water discharged upwards, good vertical channel silt, silt soil quality, red filling of unsaturated cohesive and miscellaneous fill drainage consolidation method of soft foundation treatment, greatly reducing the soft soil consolidation time. Drainage board works: drainage board flapper machine inserted into the soft ground, preloading loads in the upper part, the gap in the soft ground water discharged by the drainage board the upper bedding sand or horizontal plastic pipes from other places discharge to accelerate the consolidation of soft ground. In soft soil treatment, the role of the drainage board design, construction equipment is basically the same with bags of sand. Drainage board the advantages of soft soil foundation reinforcement treatment is good drainage flow, drainage effect is guaranteed. 2 materials have good strength and ductility, suitable for ground deformation capacity without affecting the performance of drainage drainage board section size small, small injections of the drainage board disturbance to the foundation. 4 flapper construction in the ultra-soft ground. Fast construction, short construction period, each flapper machine daily flapper more than 15,000 meters, the cost is lower than the bags of sand. For deep soft soil drainage consolidation method for reinforcement, from the technical and economic considerations, drainage board is almost the only cost-effective and feasible method.
