Urban rail transit shock absorption type floating slab rail system
An urban rail transit shock absorption type floating slab rail system comprises a floating plate (1), a tunnel foundation (5) and a steel rail (2). The steel rail (2) is fixed to the floating plate (1) through fasteners (3). The floating plate (1) is arranged on the tunnel foundation (5) through a vibration isolator (4). The tunnel foundation is arranged in a tunnel (8). The urban rail transit shock absorption type floating slab rail system further comprises a shock absorption device arranged on the floating plate (1), The shock absorption device is composed of shock absorption blocks (6) or shock absorption strips (10) and an elastic damping element (7) and is arranged on the floating plate (1) discretely. Some lines of the shock absorption blocks (6) are arranged within the width range of the floating plate (1), and the other shock absorption blocks (6) are arranged within the length range of the floating plate (1). The urban rail transit shock absorption type floating slab rail system is simple in structure and convenient and feasible to assemble and detach; the low-frequency-band vibration isolation effect of the floating plate is improved, the disadvantageous influence that vibration is amplified when the frequency of the floating plate is close to the inherent frequency is restrained, and the urban rail transit shock absorption and noise reduction control and the social harmonious development promotion are facilitated.
