High-speed railway ballastless track subgrade surface layer half-paving waterproof closed structure and construction method
The invention discloses a high-speed railway ballastless track subgrade surface layer half-paving waterproof sealing structure and a construction method. The invention relates to a high-speed railway ballastless track subgrade surface layer half-paved waterproof sealing structure which comprises a concrete base plate and is characterized in that high-toughness concrete sealing layer structures are paved on the upper parts of subgrade bed surface layers on two sides of the concrete base plate; the end, located on the side of the concrete base plate, of the high-toughness concrete sealing layer structure extends to the bottom of the concrete base plate, and the end portion of the extending end of the high-toughness concrete sealing layer structure is provided with a convex blocking table and is integrally poured with the concrete base plate. The high-toughness concrete structure with the end provided with the convex blocking table is used for waterproof sealing, the phenomenon that accumulated water infiltrates from the surface layer of the roadbed to the interior of the roadbed can be eradicated, slippage between the concrete base plate and the waterproof sealing layer is limited through the convex blocking table, the half-laid waterproof sealing structure is adopted, the use amount of the high-toughness concrete is reduced, and the construction cost is reduced. And the engineering cost is greatly saved.
本发明公开了一种高速铁路无砟轨道路基表层半铺防水封闭结构及施工方法。高速铁路无砟轨道路基表层半铺防水封闭结构，包括混凝土底座板，其特征是：在混凝土底座板两侧的路基基床表层上部铺设有高韧性混凝土封闭层结构，所述高韧性混凝土封闭层结构位于混凝土底座板侧的一端延伸至混凝土底座板的底部，且其延伸端的端部具有凸型挡台并与混凝土底座板浇筑为一体。本发明使用端部具有凸型挡台的高韧性混凝土结构进行防水封闭，可杜绝积水由路基表层向路基内部的下渗现象，并且通过凸型挡台限制了混凝土底座板与防水封闭层之间的滑移，采用半铺防水封闭结构，减少了高韧性混凝土用量，大大节约了工程成本。
