Composite geotextile material-broken stone hardcore horizontal enhanced drainage technology and construction process thereof
The invention relates to a composite geotextile material-broken stone hardcore horizontal enhanced drainage technology and a construction process thereof, which are suitable for drainage of a southern high underground water level pavement structure, a composite geotextile material is composed of polypropylene fiber non-woven fabric and a drainage net, and sequentially comprises a broken stone hardcore, a hydraulic conduction layer, a geotextile drainage layer and an isolation layer from top to bottom, the broken stone hardcore eliminates the capillary retardation effect, realizes rapid drainage of infiltration water and capillary rising water of the pavement structure layer in an unsaturated state, reduces damage of the infiltration water and capillary rising water to the pavement structure, prevents water from further infiltrating into a roadbed soil body to reduce the strength of the roadbed soil body, improves the bearing performance of the pavement structure and the roadbed soil body, and reduces the construction cost. And an efficient, energy-saving, environment-friendly and sustainable countermeasure is provided for pavement structure water disaster disposal.
本发明涉及一种复合土工材料‑碎石垫层水平向增强排水技术及其施工工艺，适用于南方高地下水位路面结构排水，复合土工材料由聚丙烯纤维无纺布和排水网组成，从上而下依次为碎石垫层、水力传导层、土工排水层和隔离层，碎石垫层消除毛细阻滞效应，实现在非饱和状态下将路面结构层入渗水和毛细上升水快速排除，减轻入渗水和毛细上升水对路面结构损伤，同时防止水进一步入渗路基土体而降低路基土体强度，提高路面结构和路基土体承载性能，为路面结构水灾害处置提供是高效、节能、环境友好、可持续的对策。
