Problems solved by technology

[0007] In short, how to make good use of the space of the fertilizer tank to carry out a reasonable vibration isolation design for the vibration of the transmission path 1 has so far been scarce, and it is still a research problem for non-track vibration isolation of buildings around the ground line
In addition, after using the fertilizer tank space for vibration isolation design, the research on construction methods in specific construction stages is also relatively rare, and there is a lack of relevant engineering experience and construction guidance

Abstract

The invention discloses a building combined vibration damping system. The building combined vibration damping system comprises a vibration isolator body; the vibration isolator body is arranged in a fertilizer groove reserved between one side of a building and the side wall of a foundation pit; the vibration isolator body comprises a waterproof coating layer, an extruded polystyrene board layer, awall type vibration damping board layer, two geotextile layers, a concrete layer and a plain soil backfill layer which are arranged in sequence; and one side of the waterproof coating layer is attached to the building. Through the combined vibration damping system, vibration waves are reduced, and the function of protecting the building is achieved. The invention further discloses a constructionmethod of the building combined vibration damping system. The method comprises the following steps of base wall treatment, waterproof coating treatment of an outer wall, bonding of extruded polystyrene boards, bonding of wall type vibration damping boards, bonding of two layers of geotextile, pouring of the concrete layer, forming of a vibration isolation trench and backfilling of plain soil. Thebuilding combined vibration damping system formed through the construction method has better vibration damping effect.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a building combined vibration damping system, and also relates to a construction method of the building combined vibration damping system. Background technique [0002] When building buildings on the land close to the ground line of rail transit, the primary problem is the environmental vibration and noise pollution caused by train operation. For vibration problems, the available methods can be roughly divided into two categories, one is track vibration isolation; the other is non-track vibration isolation. Wherein, rail vibration isolation refers to vibration isolation on rails, and existing methods include vibration isolation by means of vibration-damping fasteners or vibration-damping ballast beds. Non-track vibration isolation refers to the method of vibration isolation in the area between the track and the building, as well as on the building itself. E...
