High-speed railway widening subgrade structure
The invention discloses a high-speed railway widening subgrade structure which is a reinforced concrete structure. The high-speed railway widening subgrade structure comprises a frame structure and a pile foundation, the frame structure disposed on the pile foundation is inverted trapezoidal and composed of a top plate, four inverted trapezoidal rib plates and bearing plates, the top plate is in the shape of an integral plate, each bearing plate is in the shape of a batten, and the inverted trapezoidal rib plates are arranged between the top plate and the bearing plates. The frame structure is a triple frame, and the four inverted trapezoidal rib plates are vertically arranged between the top plate and the bearing plate. The file foundation is composed of reinforcing foundation piles and is formed by reinforced concrete borehole injection. The pile foundation is connected with frame structure into a whole through the bearing plates, and the reinforcing foundation piles of the pile foundation are arranged under the bearing plates of the frame structure. The top ends of the reinforcing foundation piles are connected with the bottom surfaces of the bearing plates, the three to five reinforcing foundation piles are arranged under each bearing platform according to the height of the frame structure, and the reinforcing foundation piles are perpendicular to the bearing plates. The high-speed railway widening subgrade structure has the advantages of simple structure, high strength, convenience in construction and small influence on existing railway operation and existing subgrade settlement and the like, thereby being particularly applicable to high-speed railway subgrade widening sections.
