Building foundation vibration isolation structure and construction method thereof

Abstract

The invention relates to the technical field of building vibration attenuation, and discloses a building foundation vibration isolation structure and a construction method thereof. The building foundation vibration isolation structure comprises a first side portion vibration isolation assembly and a second side portion vibration isolation assembly which are arranged on the outer side of a buildingfoundation side wall from bottom to top in sequence; the first side portion vibration isolation assembly comprises brick membrane, a first waterproof layer and a first vibration attenuation layer which are overlapped from outside to inside in sequence, and the first vibration attenuation layer is arranged on an outer side surface of the building foundation side wall; the second side portion vibration isolation assembly comprises a second waterproof layer and a second vibration attenuation layer which are overlapped from inside out in sequence, and the second waterproof layer covers the outerside surface of the building foundation side wall; and an upper edge of the first waterproof layer is connected with a lower edge of the second waterproof layer. The building foundation vibration isolation structure divides the vibration isolation assemblies of the building foundation side wall into upper and lower segments, construction is simple, the construction cost is saved, a construction space is optimized, waterproof and vibration attenuation effects are excellent, and conditions are provided for a hot-melt paving mode of a waterproof coiled material.

Description

technical field [0001] The invention relates to the technical field of building vibration reduction, in particular to a building foundation vibration isolation structure and a construction method thereof. Background technique [0002] With the continuous advancement of my country's urbanization process, available land resources are becoming more and more scarce, and rail transit stations, depot superstructures and properties along the lines are developing rapidly. Although rail transit facilitates people's daily travel, the problems of vibration and noise pollution generated by it cannot be ignored. Among them, the main source of pollution is noise on the ground, that is, elevated lines, and vibration and secondary structure noise on underground lines. In some areas, the vibration caused by rail transit has become one of the most sensitive environmental vibration sources for the public. It can be seen that it is very necessary to take vibration control measures for sensitiv...
