Prefabricated and assembled composite vibration isolation barrier and construction method thereof

Abstract

The invention discloses a prefabricated and assembled composite vibration isolation barrier. A U-shaped cavity is defined in each U-shaped prefabricated concrete groove body, lifting rings are fixed to the top ends of side plates of the U-shaped prefabricated concrete groove bodies, meanwhile, the multiple U-shaped prefabricated concrete groove bodies are distributed along the same straight line, the opening ends of the side ends of every two adjacent U-shaped prefabricated concrete groove bodies are in butt joint such that the multiple U-shaped cavities are in communication, meanwhile, every two adjacent U-shaped precast concrete groove bodies can be detachably connected, then cast-in-place EPS light soil slurry is poured into the U-shaped cavities, and the EPS light soil slurry forms an EPS filling body after being solidified. The invention discloses a prefabricated and assembled composite vibration isolation barrier and a construction method thereof, which not only can effectively reduce vibration caused by rail transit, but also can guarantee the stability of an excavation section foundation, so that the service life of the prefabricated assembled composite vibration isolation barrier is prolonged, and the later maintenance frequency and cost are reduced.

Description

technical field [0001] The invention relates to the technical field of environmental vibration control, in particular to a prefabricated and assembled composite vibration isolation barrier for environmental vibration control and a construction method thereof. Background technique [0002] Railway transportation has played an important role in the process of urbanization and modernization, but its environmental vibration and noise impact on surrounding sensitive buildings has become increasingly prominent. The main reason for the excessive vibration of the external environment caused by rail transit is that sensitive buildings are getting closer and closer to the line. However, as the construction land becomes more and more tense, close contact between rail transit lines and sensitive buildings is inevitable. Engineering vibration control measures to solve this dilemma. Transmission path vibration control measures are an important way to reduce the impact of rail transit ope...

Problems solved by technology

[0003] The main form of vibration control measures for the transmission path is the vibration isolation barrier. Discontinuous barriers such as non-continuous barriers and horizontal wave-resistance plate barriers, but the existing test and theoretical research results show that various types of vibration-isolation barriers such as empty trenches and foam boards have certain wave resistance effects and attenuation characteristics for vibration waves. In terms of vibration isolation ditch can have a strong attenuation effect on vibration, but the installation of vibration isolation barriers such as ditch is not conducive to the stability of the surrounding rock and soil, resulting in difficulties in later maintenance and maintenance
