Description
Technical field
The utility model is related to technical field of building construction, more particularly to a kind of basement composite external wall anti-cracking and seepage control structure
Construction.
Background technology
The quickening of urbanization process causes the growing tension of urban land resource, particularly in the environment for building limit for height
The exploitation of the lower underground space and the highest attention for rationally utilizing more developer.In recent years, the fast development of underground engineering causes
Engineering accident hidden danger of quality it is more frequent, the particularly common quality defect such as percolating water of underground engineering long-standing problem engineer
.Armored concrete undergrounds such as " the two wall superposed types ", " two walls separate, are independently arranged formula ", " two wall Integral types " that uses at present
Outdoor wall construction, because it is influenceed by the temperature difference, the contraction of concrete itself and Water And Earth Pressures；In addition design, material, coagulation
Soil coordinates the when various factors such as construction, and outer wall of basement structure quite a lot exists vertical, oblique through splitting according to investigations
Stitch and percolating water, even if two walls, which are separated, can set up waterproof layer on the outside of the outer wall of basement for the formula that is independently arranged, but eventually because of its protection
Layer is often not in place and backfill expects fragile waterproof layer and can still occur outer wall of basement percolating water.Need to carry out for quite a long time
Leak stopping is repaired repeatedly, not only needs to spend an expensive leak stopping cost of repairs, produces very big worry, and influence basement uses work(
Can, and steel bar corrosion at outer wall of basement percolating water can be caused to rot, influence its service life.It is not known for design and requires
Or else some practicable crack and leak preventing measures are taken under the premise of closed sticked type basement composite external wall processing method, are easily made
Into external wall structure Seepage, it is bigger that the later stage repairs difficulty.
Utility model content
The purpose of this utility model is that the defect for overcoming prior art to exist can effectively prevent basement from answering there is provided one kind
Box-like out-wall crack and the external wall structure of seepage construction.
The utility model is realized by following technical scheme：
A kind of basement composite external wall anti-cracking and seepage control structure construction, including diaphram wall and outer wall of basement, its feature
It is, waterproof layer, damp-proof layer and heat-insulation layer are provided between the diaphram wall and outer wall of basement, and the waterproof layer is arranged at
On the even curface of diaphram wall, the damp-proof layer is laid on waterproof layer, and the heat-insulation layer is pasted on damp-proof layer.It is anti-
Only building enclosure diaphram wall protruding parts produces stress concentration to it and causes cracking phenomena to enter after outer wall of basement concrete placings
And seepage is produced, therefore before basement structure outer wall construction, building enclosure diaphram wall surface irregularity is rebuild in advance
Region, and then lay waterproof layer, damp-proof layer, heat-insulation layer successively on the surface of smooth diaphram wall body.
As a further improvement, the waterproof layer includes cement sand bed and waterproof layer, the cement sand bed
It is coated on the even curface of diaphram wall, the waterproof layer is coated in cement mortar layer surface.
As a further improvement, the thickness of the cement sand bed is 8mm.
As a further improvement, the damp-proof layer is malthoid layer, and the malthoid layer is two layers.
As a further improvement, the heat-insulation layer is polyethylene flaggy.
As a further improvement, the thickness of the polyethylene flaggy is 40-50mm.
As a further improvement, the steel fabric sheets of 4@of Φ 200 are laid in the outer surface of the outer wall of basement.
The beneficial effects of the utility model are：It ensure that basement structure outer wall has phase with foundation ditch diaphram wall as best one can
Pair can with the space of displacement, be capable of high degree reduction basement combined type out-wall crack and seepage probability.
