Description
Technical field
The utility model relates to a kind of isolation barrier of isolating Subway Vibration.
Background technology
Current China city underground is in the large-scaled construction period, and subway passes through cultural relics and historic sites along the line, city museum, esidential building and types of functionality to vibration sensing and build, produces, life creates impact that is long-term, that be difficult to avoidance on people.Although Subway Vibration is harmful to human safety not, will produce normally people for a long time in the past, lived and healthy will to produce a very large impact.Subway Vibration belongs to the damage of micro-vibrating fatigue to historical relic harm, but as time goes by, this persistent small size damage is accumulated over a long period, and historical relic also will be caused to destroy.Therefore, find a kind of safe and effective, implement isolating technique technical measures easily, reduce the impact of Subway Vibration on surrounding building and be very important.
Utility model content
The utility model provides a kind of Subway Vibration isolation barrier, solve the technical problem that Subway Vibration has an impact to surrounding building.
The utility model solves the technical scheme that its technical problem adopts:
What this Subway Vibration isolation barrier was made up of jointly one or the above slider of twice has continuity or periodic barrier, and described slider is arranged between subway tunnel and building foundation, and vertically gos deep in soil response.
Described slider is at least one row's isolation pile or at least one deck diaphragm wall, or is the combination of isolation pile and diaphragm wall.
Described isolation pile is reinforced concrete pile, steel pipe pile, broken stone pile, immersed tube sand-gravel pile, cement mixing method, rotary churning pile, lime-soil compaction pile or CFG.
Described diaphragm wall is concrete continuous wall, rubber diaphragm wall or PVC diaphragm wall.
The arrangement form of described slider is linear, fold-line-shaped or cyclic curve shape.
When described slider has more than twice, the maximum outline spacing of slider is not less than 1.5 times of subway tunnel buried depth.
When described slider has more than twice, the degree of depth of slider gets the greater in building foundation buried depth and subway tunnel buried depth, and is not less than 25m;
When the buried depth of bedrock in soil response is less than 25m, at the bottom of slider, go deep into basement rock 1m.
The equivalent thickness of described slider is less than 500mm.
The length of described slider should be parallel to the width in subway tunnel direction by building foundation, put angle, and determine the length of slider according to the position of slider to carry out 30 ° ~ 60 ° perpendicular to subway tunnel direction.
The beneficial effects of the utility model are as follows:
The utility model by multiple vertically go deep into that isolation pile in soil response or diaphragm wall etc. form there is continuity or periodic barrier.Isolation barrier is made up of jointly one or multi-channel slider, and per pass slider can adopt different materials or different arrangement form.Isolation barrier does not directly contact with building, but by the mode of diffuse reflection, refraction, the mechanical wave produced by Subway Vibration is decayed, thus improves the safety of personnel's comfortableness and equipment, historical relic etc. in building, building.
The utility model simple structure, is convenient to implement, can effectively reduces the impact of Subway Vibration on its surrounding building, and the existing building that can be widely used in subway periphery and the Subway Vibration planning to build building control.
