A vibration-reducing and isolating sheet pile structure and its construction method

Abstract

The invention discloses a vibration reduction and isolation plate pile structure and a construction method thereof. A body structure of the vibration reduction and isolation plate pile structure is a vibration reduction and isolation thin plate arranged in the part, between a vibration source and a protected object, of the soil body, the bottom of a plate pile is of a prefabricated sharp conical structure, a rigid plate is arranged on the lower portion of the plate pile, a sandwich plate is arranged on the upper portion of the plate pile, the rigid plate and the sandwich plate are plates made of concrete or steel materials or other high-strength materials, and the sandwich core materials of the sandwich plate are rubber or pitch or polyurethane or other soft damping materials. Plane arrangement modes include a fold line mode, a straight line mode, a continuous mode, a non-continuous mode and other modes, static pressing serves as the construction method, and in the plate put-in construction process, the two wings of the plates at the same pile position are protected and held through steel channels. The vibration reduction and isolation structure is arranged between the vibration source and the protected structure, a medium variation belt is formed, vibration is effectively prevented from spreading to the protected structure, the vibration reduction and isolation effect is obvious, the construction speed is high, the manufacturing cost is low, and durability in use is achieved.

Description

technical field [0001] The invention relates to a railway vibration-reducing and isolating structure, in particular to a vibration-reducing and isolating sheet pile structure arranged between a vibration source and a protected object and a construction method thereof. Background technique [0002] During the operation of the railway, the vibration generated when the train passes the railway subgrade will propagate through the foundation bed to the surrounding foundation along the line, which will cause discomfort to the residents living in the surrounding area, damage the structural buildings, and affect the normal production of some high-precision industries. . Due to a series of adverse effects caused by vibration, it has been listed as one of the seven major environmental hazards internationally. [0003] Among the measures to control the vibration transmission of railway subgrade, the most effective measure is to reinforce the subgrade bed and its foundation, but for ex...
