Composite directional water guide and drainage structure driven by modified wicking
The invention discloses a modified wicking driven composite directional water guide and drainage structure which comprises a PVC soft plate base body, a plurality of water collecting grooves are formed in the upper surface of the PVC soft plate base body, a plurality of rough surface capillary drainage grooves are formed in the lower surface of the PVC soft plate base body, modified wicking drainage yarn is arranged in the water collecting grooves and the rough surface capillary drainage grooves, and the modified wicking drainage yarn is arranged in the PVC soft plate base body. A water-permeable geotextile is arranged on the upper surface of the PVC soft plate base body, and the water-permeable geotextile and the upper surface of the PVC soft plate base body are fixed through a hot melt adhesive bonding layer. The composite directional water guide and drainage structure under modified wicking driving is used for solving the problems that a traditional roadbed drainage geotechnical material can only drain gravity water and cannot suck and drain capillary water in a roadbed, and local water accumulation is caused by capillary fracture.
本发明公开了一种改性芯吸驱动下的复合定向导排水结构，包括PVC软质板基体，所述PVC软质板基体的上表面设有若干个集水槽，下表面设有若干个糙面毛细排水槽，集水槽和糙面毛细排水槽内设有改性芯吸排水纱线，所述PVC软质板基体的上表面设有透水土工织物，透水土工织物和PVC软质板基体的上表面通过热熔胶粘接层固定。本发明提出的改性芯吸驱动下的复合定向导排水结构，用于解决传统路基排水土工材料只能排出重力水、无法吸取排出路基中毛细水和毛细断裂引起的局部水分蓄积的问题。
