Ardealite highway subgrade protection engineering design method
The invention provides an ardealite highway subgrade protection engineering design method. The ardealite highway subgrade protection engineering design method comprises the steps that a slope surface of a slope with an ardealite subgrade completed is leveled and tamped; a water glass and calcium chloride mixed solution is sprayed on the slope surface of the side slope, rainwater is prevented from permeating into a roadbed channel, and the strength and anti-freezing performance of the phosphogypsum roadbed are improved; reinforced concrete frame beams with the thickness of 50-60 cm, the width of 20-30 cm and the strength of 25 MPa are manufactured on the slope according to the vertical and horizontal spacing of 5 m * 3 m; a drainage ditch is arranged on the roadbed slope every 30-50 m; after the cement concrete of the frame beams and the drainage ditches reaches the design strength, the frames are filled with planting cohesive soil; grass seeds and/or low shrub tree seeds with developed root systems are sown and planted to stabilize the ardealite roadbed slope, and the greening and water sealing requirements are met. According to the ardealite highway subgrade protection engineering design, the ardealite highway subgrade is totally closed, and the functions of protecting the subgrade to be stable, preventing and draining water, greening and beautifying, protecting the environment and the like are achieved.
本发明提供了一种磷石膏公路路基防护工程设计方法，包括：对已完成磷石膏路基的边坡坡面整平夯实；对边坡坡面喷洒水玻璃和氯化钙混合液，封闭雨水渗入路基通道，提高磷石膏路基强度和抗冻性能；在边坡上按照5m×3m的竖向和水平间距制作厚度50~60cm、宽度20~30cm，强度25MPa的钢筋混凝土框架梁；在路基边坡上每30~50m设置一道排水沟；框架梁和排水沟的水泥混凝土达到设计强度后在框架内填筑种植粘性土；撒播种植根系发达的草种和/或低矮灌木树种以稳定磷石膏路基边坡，满足绿化及封水要求。本发明磷石膏公路路基防护工程设计对磷石膏公路路基进行全封闭，具有保护路基稳定、防排水功能、绿化美观和环境保护等功能。
