Vibration isolation plate device in soil matrix treatment engineering and construction technology thereof

Abstract

The invention discloses a vibration isolation plate device in soil matrix treatment engineering. The device comprises a vibration isolation array composed of multiple parallel vibration isolation units, wherein the front end of the first vibration isolation unit located at one end of the vibration isolation array is closed to prevent soil from falling, the connection parts of every two adjacent vibration isolation units overlap to block soil, each vibration isolation unit comprises two vibration isolation veneers arranged in parallel in the vertical direction, and vibration isolation modules are arranged between every two vibration isolation veneers at intervals. The invention further discloses a construction technology using the device. Due to the arrangement of the vibration isolation veneers in an open trench, collapse of a trench wall during dynamic compaction caused by vibration can be avoided, and the vibration isolation effect of the vibration isolation trench can be guaranteed to the maximum degree. Due to the fact that the vibration isolation modules are arranged between the vibration isolation veneers, the vibration isolation veneers can be supported, wave energy can be absorbed, and the influence of vibration on nearby buildings can be reduced. According to the device, the vibration isolation effect of the vibration isolation trench is improved greatly, and the usage of filling materials is reduced.

Description

[0001] technical field [0002] The invention relates to a vibration-isolation plate device suitable for soil foundations and a construction process thereof which can be widely used in vibration isolation of surrounding buildings in a series of civil engineering such as dynamic compaction construction, blasting, and rail transit. Background technique [0003] In industrial production, there are three types of vibration sources that often cause vibration to affect the environment. [0004] The first type is the transient vibration source, such as the drop hammer hammering the foundation in the dynamic compaction operation, and the chemical energy released by the explosive in the blasting project. Wide, with a wide range of influence. [0005] The second category is steady-state vibration sources, such as air compressors, vibrating screens, refrigeration compressors, fans, water pumps, etc. These vibration sources are regularly and periodically repeated. [0006] The third c...

AI Technical Summary

Problems solved by technology

Practice has proved that the vibration isolation effect of fly ash is not ideal, the extreme matching ratio is difficult to grasp, and the long-term vibration isolation effect is even worse; the cost of concrete filling ditch is too high, which is very uneconomical

All in all, excavating a large area of ​​vibration isolation ditch requires a lot of earthwork, which is time-consuming and laborious; and due to the need for filling materials, the vibration isolation effect is not satisfactory
