Problems solved by technology

However, the vibration isolation embankment is set at the toe of the railway slope, and its vibration isolation effect is limited on the completed railway without the toe of the slope.
At the same time, the vibration isolation ditches and vibration isolation dikes used in the prior art are continuously arranged along the direction of the railway, which only consumes a huge amount of materials, and it is easy to cause overall stability damage in the follow-up maintenance process, which is not conducive to long-term stability

Abstract

The invention discloses a discontinuous vibration isolation belt for reducing railway environment vibration. The vibration isolation belt is composed of a row of vibration isolators and a row of vibration isolation pits, wherein the vibration isolators and the vibration isolation pits are away from a railway track by a certain distance and are parallel to the railway direction. The vertical distance between the vibration isolation pit and the vibration isolation body is 2-4m; the vibration isolator is in a step-shaped rectangular pyramid shape, the bottom face of the vibration isolator is in a 2 m * 3 m square shape, and the step height is 20-30 cm. The distance between every two adjacent vibration isolators is 2-3 m. The vibration isolation pit is in an inverted quadrangular frustum pyramid shape, the top face of an opening of the vibration isolation pit is a square of 3 m * 3 m, the bottom face of the opening of the vibration isolation pit is a square of 1 m * 1 m, and the depth of the vibration isolation pit is 1-1.5 m. The distance between every two adjacent vibration isolation pits is 2-3 m. The vibration isolation belt is composed of the intermittent vibration isolation bodies and the vibration isolation grooves, construction is convenient, and maintenance is easy.
