Assembly type prestress roadbed structure and construction method
The invention relates to an assembly type prestress roadbed structure. The structure comprises a broken stone hardcore, a concrete base, lightweight concrete blocks, lightweight concrete cushion blocks and an upper packing layer, wherein the broken stone hardcore is composed of a lower part and an upper part; the center of the concrete base is provided with upper part, and the lightweight concreteblocks and the upper packing layer are arranged on the concrete base; prefabricated grooves are formed in the two ends of the concrete base, and reinforced concrete prefabricated slabs are embedded in the prefabricated grooves; the lightweight concrete blocks are arranged between the two reinforced concrete prefabricated slabs; cast-in-place micro-expansion high-fluidity mortar is arranged between every two adjacent lightweight concrete blocks; the lightweight concrete cushion blocks and steel cables are arranged between every two adjacent layers of lightweight concrete blocks, and the two ends of each steel cable are fixed to the reinforced concrete prefabricated slabs; waterproof geotechnical cloth I is arranged between the bottommost lightweight concrete block and the upper part as well as between the bottommost lightweight concrete block and the concrete base; and waterproof geotechnical cloth II is arranged between the topmost lightweight concrete block and the upper packing layer. The invention further discloses a construction method of the structure. The structure is stable, and rapid construction can be achieved.
本发明涉及一种装配式预应力路基结构，该结构包括碎石垫层、混凝土底座、轻质混凝土砌块、轻质混凝土垫块和上部填料层。碎石垫层由下部和上部构成；混凝土底座中心设上部，其上设轻质混凝土砌块、上部填料层；混凝土底座两端设预制槽，预制槽内嵌钢筋混凝土预制板；两个钢筋混凝土预制板之间设轻质混凝土砌块；相邻两个轻质混凝土砌块之间设现浇微膨胀高流动性砂浆；相邻两层轻质混凝土砌块之间设轻质混凝土垫块和钢索，该钢索两端固定在钢筋混凝土预制板上；最底层轻质混凝土砌块与上部及混凝土底座之间设防水土工布Ⅰ；最顶层轻质混凝土砌块与上部填料层之间设防水土工布Ⅱ。本发明还公开了该结构的施工工法。本发明结构稳定，可实现快速施工。
