Abstract
The invention belongs to the field of underground engineering construction, and in particular, relates to an underground structure lining wall and underground continuous wall overlapped surface structure and a construction method thereof. The structure is characterized by comprising an underground structure lining wall and an underground continuous wall; the underground continuous wall is constructed on the outer side of the underground structure lining wall to serve as a surrounding structure; profiled steel sheets are paved between the underground structure lining wall and the underground continuous wall, and are concave-convex; concrete protection layers are arranged between the profiled steel sheets and vertical reinforcements on the inner side of the underground continuous wall; the adjacent profiled steel sheets are joined with each other; fixed pieces are arranged between the profiled steel sheets and the vertical reinforcements on the inner side of the underground continuous wall; the profiled steel sheets are connected with the fixed pieces; and the fixed pieces are fixedly welded with reinforcement cages of the underground continuous wall. As the profiled steel sheets are arranged on the inner side of the underground continuous wall, the underground structure lining wall and the underground continuous wall form an overall stress structure component; and meanwhile, the profiled steel sheets serve as waterproof units of the underground structure lining wall.
Description
Technical field
The invention belongs to underground engineering construction field, more particularly to a kind of underground structure inwall and diaphram wall overlapping surface construction and its construction method of construction of underground structure suitable for subway station, underground parking garage and skyscraper.
Background technology
When underground structure inwall outside has performed diaphram wall as its foundation pit enclosure structure, structure design is usually descended to consider that diaphram wall participates in underground structure stress, it is normal at present to carry out calculating design by composite wall or overlapping wall.Overlapping wall is that diaphram wall is poured with after underground structure inwall to form a whole force structure component, i.e. by manually diaphram wall inner side being dug into male and fomale(M＆F) or arranging steel tie makes diaphram wall couple together with underground structure inwall, and structure roof, the tension reinforcement of middle plate and base plate is attached by embedded bar connector and diaphram wall, positive pressure and shearing can be transmitted between diaphram wall and underground structure inwall, general underground structure liner wall thickness can use 400mm, the bending rigidity of overlapping wall is larger, and the arrangement of reinforcement on the outside of underground structure inwall is less.
Composite wall to be referred to and be provided with watertight insulation between diaphram wall and underground structure inwall, diaphram wall, underground structure inwall are two independent primary structure members, underground structure liner wall thickness generally requires 700mm-800mm, the bending rigidity of composite wall is less, and arrangement of reinforcement is more on the outside of underground structure inwall；Watertight insulation on the outside of inwall forms an entirety with structure roof waterproof layer, base plate waterproofing, and the water resistance of composite wall is preferable.Diaphram wall only undertakes the support action in construction stage engineering, and two components not Transfer of Shear, the steel bar stress of structure roof, middle plate and base plate need not be connected with diaphragm wall；In operational phase, diaphram wall participates in structural anti-buoyancy effect.
According to《Urban track traffic design specification》, when superposed surfaces do not match somebody with somebody lacing wire, diaphram wall medial surface dabbing is required：Dig 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.Face is poured due to there is new-old concrete between diaphram wall and structure inwall, crack easily occurs in structure inwall, cause structure inwall percolating water, structure reinforcing bars easily to corrode, reduce the durability of structure.In the built subway station by overlapping wall design, much there is structural percolating water, later stage Treatment Measures to Leakage is costly.
The content of the invention
Perform manpower needed for male and fomale(M＆F), solve the deficiency of underground structure inwall percolating water to save diaphram wall, it is an object of the invention to provide a kind of underground structure inwall overlaps surface construction and its construction method with diaphram wall.
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 inwall, diaphram wall, the underground structure inwall outside has performed diaphram wall as its building enclosure, the underground structure inwall, profiled sheet is equipped between diaphram wall, the profiled sheet is in concave-convex, the diaphram wall inner side is provided with diaphram wall inner side vertical reinforcement, concrete cover is provided between the profiled sheet and diaphram wall inner side vertical reinforcement, mutually overlap between the adjacent profiled sheet, fixture is provided between the profiled sheet and diaphram wall inner side vertical reinforcement, the profiled sheet is connected with fixture, the fixture is welded and fixed with the steel reinforcement cage of diaphram wall.
The fixture is cableway or shaped steel.
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, the peak line of the profiled sheet, hollow line are horizontally disposed with.
The profiled sheet is rolled using galvanized steel plain sheet or general steel plate.
Profiled sheet wave height >=the 10mm, is connected between the profiled sheet using pulling rivet.
By welding or securing member connection between the profiled sheet and fixture.
A kind of underground structure inwall overlaps the construction method of surface construction with diaphram wall, it is characterised in that comprise the following steps：（1）First make diaphram wall steel reinforcement cage by usual method, then some fixtures are set in steel reinforcement cage top surface, by being welded and fixed between fixture and diaphram wall steel reinforcement cage, finally profiled sheet is laid on fixture, mutually overlap between profiled sheet, connected using pulling rivet between profiled sheet, by welding or securing member connection between profiled sheet and fixture；（2）Soil body stage excavation in foundation ditch, often excavates one layer of earthwork, and diaphram wall inner side profiled sheet surface is cleaned, and rubber strip is laid between underground continuous wall connector or so profiled sheet, and rubber strip is overlapped with profiled sheet, and using fluid sealant adhering and sealing.
The step（2）In, transverse joint or vertical abutment joint are using welding or sealant sealing between the continuous profiled sheet within the walls of each width.
Beneficial effects of the present invention are：
1st, diaphram wall inner side is provided with concavo-convex profiled sheet, diaphram wall inner side self-assembling formation male and fomale(M＆F), it is not necessary to artificial chisel diaphram wall superposed surfaces in the present invention；
2nd, than artificial chisel male and fomale(M＆F) reliability, shear bond strength bearing capacity is significantly improved the quality of underground structure inwall and diaphram wall superposed surfaces；
3rd, profiled sheet defines the steel plate waterproof layer on the outside of underground structure inwall, solves current underground structure overlapping wall and percolating water phenomenon easily occurs.
