Description
Technical field
The present invention relates to the advanced enclosed construction of poured band of outer wall of basement and construction method, belongs to industry and civil buildings master
Outer wall of basement and post empiricism field in body structure, it is mainly used in advanced protection and the later stage of poured band of outer wall of basement
Post-cast strip concrete pouring construction in.
Background technology
In the construction of outer wall of basement, due to single construction wall length limitation and construction in Deformation control will
Ask, need to set post-cast strip on outer wall of basement.The construction operation carried out before poured band of outer wall of basement closing is not only
With potential safety hazard, and debris, rainwater and construction water are easily accessible in basement before the closing of post-cast strip, influence post-cast strip
Pouring quality and normal construction.Poured band of outer wall of basement concreting time interval is longer, generally requires underground body junction
Structure just carries out the pouring construction of post-cast strip after constructing, therefore such as can make outdoor backfill without the advanced closing of post-cast strip
Process can not be carried out, and can not also give agent structure and equipment installation to provide necessary place.
Poured band of outer wall of basement is closed is constructed using concrete prefabricated closed plate in advance at present, its enclosed construction and
Construction method is in document " card slot type formwork construction technology on the outside of poured band of outer wall of basement（《Construction technology》, 2015,44
（23）：85-87）" disclosed in, the earth-retaining antiseepage problem of the advanced enclosed construction in post-cast strip is which solved, but still there are the following problems：
（1）Enclosed construction is assembled by polylith prefabricated board, easily tilts, shifts in construction, is closed when causing later stage post-cast strip to pour
Structure seriously becomes position influence construction under malformation；（2）Enclosed construction does not have barrier properties in itself, in outside because construction becomes
When waterproof layer tears and destroyed when shape is larger, the waterproof of enclosed construction can not work；（3）Outer wall of basement and post-cast strip coagulation
Soil pours formwork complexity.
The content of the invention
It is an object of the invention to for technical problem existing for the advanced enclosed construction of existing poured band of outer wall of basement, carry
A kind of advanced enclosed construction in post-cast strip and construction method are gone out, using the closed plate on-site consolidation with neck and watertight rubber bar
And entirety is linked as by dowel, while steel plate for sealing water and accessory structure are set in closed plate, reach sealing, earth-retaining, formwork
Deng technique effect.
In order to realize above-mentioned technical purpose, present invention employs following technical scheme：
A kind of advanced enclosed construction of poured band of outer wall of basement, it is characterised in that including closed plate, brick setting overcoat,
