Description
Technical field
This utility model belongs to underground engineering construction field, and more particularly, to one kind is applied to subway station and shield well underground
Structure inwall overlaps surface construction with diaphram wall.
Background technology
When having performed diaphram wall outside underground structure inwall as its foundation pit enclosure structure, general underground structure
Design will consider that diaphram wall participates in underground structure stress, often carries out calculating design by composite wall or overlapping wall at present.Overlapping
Wall be by diaphram wall with after pour underground structure inwall and form a whole force structure component, that is, pass through artificial by underground
Dig into male and fomale(M＆F) inside diaphragm wall or pre-buried steel tie makes diaphram wall couple together with underground structure inwall, underground is even
Positive pressure and shearing can be transmitted, general underground structure liner wall thickness can use between continuous wall and underground structure inwall
400mm, the bending rigidity of overlapping wall is larger, and the arrangement of reinforcement outside underground structure inwall is less.
According to " urban track traffic design specification ", when superposed surfaces do not join lacing wire, diaphram wall medial surface dabbing will
Ask: dig out cordierite and show up, male and fomale(M＆F) mean depth 20mm.Diaphram wall medial surface digs male and fomale(M＆F), needs a large amount of manpowers, applies
Work order position, through conventional excavator dabbing, is easily destroyed continuous wall concrete, and the quality of superposed surfaces is also not easy to detect.
Utility model content
Perform manpower needed for male and fomale(M＆F) in order to save diaphram wall, the purpose of this utility model is to provide a kind of ground
Lower structure inwall overlaps surface construction with diaphram wall.
The technical scheme that this utility model is adopted is:
A kind of underground structure inwall and diaphram wall overlapping surface construction it is characterised in that: include underground structure liner
Wall and diaphram wall, have performed diaphram wall as its building enclosure, described underground outside described underground structure inwall
Diaphragm wall leans on horizontal direction on underground structure inwall side to be provided with channel-section steel, and described channel-section steel passes through in fixture and diaphram wall
Side reinforcement welding firmly, in the u shape groove of described channel-section steel, filled up by the concrete of underground structure inwall by space.
