High-fill highway roadbed valley permanent and temporary combined drainage system and construction method thereof
The invention discloses a permanent and temporary combined drainage system for a high-fill highway roadbed valley and a construction method thereof. The drainage system comprises a blind ditch unit and a pipe culvert unit. Wherein the blind ditch unit is fixedly arranged above a hard foundation of an original valley river channel, the pipe culvert unit is fixedly arranged above the blind ditch unit, and the blind ditch unit and the pipe culvert unit are separated through a rubble inverted filter layer and anti-seepage geotechnical cloth; in the non-rainy season period, the blind ditch unit arranged underground meets drainage of surface water, underground water, fissure water, moderate rain and rainfall below the ground water and the underground water near a roadbed fill, and under the condition that the blind ditch cannot effectively and rapidly drain water in the rainstorm period, the pipe culvert unit arranged above the blind ditch unit assists in drainage; a drainage system comprising an underground blind ditch unit and an overground pipe culvert unit is built in an original valley river channel, the flow direction of surface water flow is effectively controlled by applying the geological landform of the original valley, the problems that water flow is changed or accelerated, and the drainage capacity of a new valley is reduced are solved, and impact and erosion of the water flow to a roadbed and surrounding areas are reduced.
本发明公开了一种高填方公路路基沟谷永临结合排水系统及其施工方法，排水系统包括盲沟单元和管涵单元。其中，盲沟单元固定设于原沟谷河道硬质地基上方，管涵单元固定设于盲沟单元上方，且两者之间通过片石反滤层和防渗土工布分隔；在非雨季时间段，设于地底的盲沟单元满足路基填方附近地面水、地下水、裂隙水、中雨及以下程度降雨的排水，当暴雨期间盲沟无法有效迅速排水的情况下，设于盲沟单元上方的管涵单元辅助进行排水；通过在原沟谷河道建设包括位于地下盲沟单元和地上管涵单元的排水系统，运用原沟谷地质地貌，有效控制地表水流的流向，避免水流改道或加速、新生沟谷排水能力下降的问题，减少水流对路基和周围地区的冲击和侵蚀。
