Description
Technical field
The invention belongs to underground engineering construction fields, more particularly to one kind being suitable for subway station, underground parking garage and height
The underground structure inwall of the construction of underground structure of layer building and diaphram wall overlapping surface construction and its construction method.
Background technology
When having performed diaphram wall as its foundation pit enclosure structure on the outside of underground structure inwall, general underground structure
Design will consider that diaphram wall participates in underground structure stress, often carry out calculating design by composite wall or overlapping wall at present.Overlapping
Wall is that diaphram wall is poured underground structure inwall with after to form a whole force structure component, i.e., by manually by underground
Chisel makes diaphram wall be connected with underground structure inwall at male and fomale(M＆F) or setting steel tie on the inside of diaphragm wall, and ties
The tension reinforcement of structure top plate, middle plate and bottom plate is attached by embedded bar connector and diaphram wall, diaphram wall
Positive pressure and shearing can be transmitted between underground structure inwall, general underground structure inwall thickness can use 400mm, fold
The bending stiffness for closing wall is larger, and the arrangement of reinforcement on the outside of underground structure inwall is less.
Composite wall refers to that watertight insulation is provided between diaphram wall and underground structure inwall, diaphram wall,
Underground structure inwall is two independent primary structure members, and underground structure liner wall thickness generally requires 700mm-800mm, composite wall
Bending stiffness it is smaller, arrangement of reinforcement is more on the outside of underground structure inwall；Watertight insulation and structure roof on the outside of inwall is anti-
Water layer, base plate waterproofing form an entirety, and the water resistance of composite wall is preferable.Diaphram wall only undertakes construction stage engineering
In support action, Transfer of Shear, structure roof, the steel bar stress of middle plate and bottom plate and diaphragm wall need not connect two components
It connects；In service stage, diaphram wall participates in structural anti-buoyancy effect.
According to《Urban track traffic design specification》, when superposed surfaces do not match lacing wire, diaphram wall medial surface dabbing is wanted
It asks：It digs out green stone to 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.By
There are new-old concretes to pour face between diaphram wall and structure inwall, and structure inwall is susceptible to crack, causes
Structure inwall percolating water, structure reinforcing bars easily corrode, and reduce the durability of structure.It is being completed the subway by overlapping wall design
In station, much there is structural percolating water, later stage Treatment Measures to Leakage is costly.
Invention content
Manpower needed for male and fomale(M＆F) is performed in order to save diaphram wall, solves underground structure inwall percolating water not
Foot, the purpose of the present invention is to provide a kind of underground structure inwall and diaphram wall overlapping surface construction and its construction methods.
The technical solution adopted in the present invention is：
A kind of underground structure inwall overlaps surface construction with diaphram wall, it is characterised in that：Including underground structure liner
Wall, diaphram wall, the underground structure inwall outside have performed diaphram wall as its building enclosure, the underground knot

It is provided with vertical reinforcement on the inside of diaphram wall, coagulation is equipped between the profiled sheet and diaphram wall inside vertical reinforcement
Protective soil layer mutually overlaps between the adjacent profiled sheet, the profiled sheet and vertical reinforcement on the inside of diaphram wall
Between be equipped with fixing piece, the profiled sheet connect with fixing piece, and the steel reinforcement cage of the fixing piece and diaphram wall, which welds, to be consolidated
It is fixed.
The fixing piece is cableway or shaped steel.
The profiled sheet structure roof top surface absolute altitude located underground is between the absolute altitude of underground structure bottom plate bottom surface.
The profiled sheet indention.
The profiled sheet undulate, peak line, the hollow line of the profiled sheet are horizontally disposed.
The profiled sheet is rolled using galvanized steel plain sheet or general steel plate.
Profiled sheet wave height >=the 10mm is connected using pulling rivet between the profiled sheet.
It is connected by welding or fastener between the profiled sheet and fixing piece.
A kind of construction method of underground structure inwall and diaphram wall overlapping surface construction, which is characterized in that including with
Lower step：（1）It first presses usual method and makes diaphram wall steel reinforcement cage, several fixing pieces then are set in steel reinforcement cage top surface,
By being welded and fixed between fixing piece and diaphram wall steel reinforcement cage, finally profiled sheet is laid on fixing piece, die mould
It mutually overlaps between steel plate, is connected using pulling rivet between profiled sheet, by welding or tightly between profiled sheet and fixing piece
Firmware connects；（2）Soil body stage excavation in foundation pit often excavates one layer of earthwork, to profiled sheet surface on the inside of diaphram wall into
Row cleans, and rubber strip is laid between underground continuous wall connector or so profiled sheet, and rubber strip is overlapped with profiled sheet, and using close
Sealing adhering and sealing.
The step（2）In, transverse joint or vertical abutment joint are using welding between the profiled sheet in each width diaphragm wall
Or fluid sealant sealing.
Beneficial effects of the present invention are：
1, concave-convex profiled sheet is provided in the present invention on the inside of diaphram wall, self-assembling formation is concave-convex on the inside of diaphram wall
Face does not need artificial chisel diaphram wall superposed surfaces；
2, underground structure inwall and the quality of diaphram wall superposed surfaces are more reliable than artificial chisel male and fomale(M＆F), shear bond strength
Bearing capacity significantly improves；
3, profiled sheet forms the steel plate waterproof layer on the outside of underground structure inwall, solves current underground structure overlapping
Wall is susceptible to percolating water phenomenon.
