Continuous vibration attenuation and isolation structure for railway

Abstract

The invention discloses a continuous vibration attenuation and isolation structure for a railway. A filling groove serves as the major structure of the continuous vibration attenuation and isolation structure for railway, hollow cylinders which are arranged continuously and densely are arranged in the filling groove, and the space between the outer walls of the hollow cylinders and the inner wall of the filling groove is filled with a filling body. Each hollow cylinder is a double-wall corrugated pipe. EPS particle cement and soil mixing packing materials serve as the filling body. According to the continuous vibration attenuation and isolation structure for the railway, the stability of the vibration attenuation and isolation structure is guaranteed, and the design depth of the vibration isolation structure can be increased easily. Due to the fact that the light EPS particle cement and soil mixing packing materials serve as the filling body, on one hand, the stability of the double-wall corrugated pipe is guaranteed; on the other hand, the wave drag impedance ratio among different media is increased, and the vibration isolation effect is improved on the other hand.

Description

technical field [0001] The invention relates to a railway vibration reduction and isolation structure, in particular to a railway continuous vibration reduction and isolation structure arranged between a railway track and a building. Background technique [0002] Railway transportation has effectively improved the traffic environment, facilitated the travel of the people, promoted urban and rural construction and economic development, and has significant economic and social benefits. However, with the rapid development of high-speed railways and heavy-duty railways, the scale of urbanization continues to accelerate, and the vibration caused by railway transportation has also brought some negative effects to the urban and rural environments. On the one hand, excessive vibration seriously affects the normal life of passengers and people along the railway; on the other hand, vibration may also cause fatigue damage to equipment structures and surrounding buildings. And with the...

Problems solved by technology

[0004] Among the traditional vibration reduction and isolation measures to control vibration transmission, the empty ditch has the best vibration reduction and isolation effect, but it is affected by the stability of the soil itself, and the construction depth is generally shallow, which cannot achieve the ideal vibration isolation effect. Popularization and Application of Ditch in Practical Engineering

Traditional filling channels are usually filled with a single material such as concrete or foam plastics into the ditch, and no gaps are left in the middle; although this can ensure the depth requirements of the vibration isolation barrier, the cost is generally high and the vibration isolation effect is low. less than ditch
