Combined prefabricated ballast bed suitable for shock absorption and noise reduction of railway tunnel
The invention provides a combined prefabricated ballast bed suitable for shock absorption and noise reduction of a railway tunnel and belongs to the technical field of railway tunnels. The ballast bed comprises a ballast bed assembly, wherein the ballast bed assembly comprises a prefabricated shell, a damping piece, a prefabricated ballast bed plate, a sleeper, a silencing plate and a steel rail, the damping piece is arranged in the prefabricated shell, the prefabricated ballast bed plate is arranged on the side, away from the prefabricated shell, of the damping piece, the sleeper is fixedly connected to the side, away from the damping piece, of the prefabricated ballast bed plate, and the silencing plate is fixedly connected to the side, close to the sleeper, of the prefabricated ballast bed plate; the silencing plate is provided with concave convex corrugations, and the steel rail conflicts with the silencing plate and can be fixedly connected to the sleeper, a damping piece comprises a vibration isolator and an elastic piece, the vibration isolator is fixedly connected to the prefabricated shell, one end of the elastic piece is fixedly connected to the vibration isolator, and the other end of the elastic piece is fixedly connected to the prefabricated ballast bed plate. The prefabricated ballast bed not only can have better shock absorption performance, but also has a better noise reduction effect.
本发明提供了一种适用于铁路隧道减震降噪的组合预制道床，属于铁路隧道技术领域，包括道床组件。道床组件包括预制壳体、减震部、预制道床板、轨枕、消音板和钢轨，减震部设置于预制壳体内，预制道床板设置于减震部远离预制壳体的一侧，轨枕固定连接于预制道床板远离减震部的一侧，消音板固定连接于预制道床板靠近轨枕的一侧，且消音板设置有凹凸波纹，钢轨抵触于消音板，并能够固定连接于轨枕，其中，减震部分为隔振器与弹性件，隔振器固定连接于预制壳体，弹性件的一端固定连接于隔振器，弹性件的另一端固定连接于预制道床板。该装置能够不仅能够有较好的减震性能，而且还具有较好的降噪效果。
