Description
Technical field
The utility model relates to hypogee construction field, especially a kind of superposed type continuous underground wall structure.
Background technique
With the continuous improvement of economic rapid development and the level of urbanization, the exploitation of the underground space is also increasing, bright
The construction of digging method is most common construction, and diaphram wall is one of most common building enclosure in cut and cover method.
However, diaphram wall is largely all made of live underwater grouting construction at present, small part is connected prefabricatedly using complete
Wall.
There are the following problems for the ground-connecting-wall of live underwater grouting construction:
First, wait concrete setting to lead to claim for eot；Cast-in-place diaphram wall is as underground large-sized concrete supporting
Structure, earth excavation is needed to wait diaphram wall concrete setting and can further be constructed after reaching some strength, and city
City's underground space construction requirements shorten the construction period as far as possible, and cast-in-place ground-connecting-wall does not obviously meet the rapid construction of urban underground space construction
It is required that.
Second, quality is not easy to guarantee when pouring；When the underwater casting of ground-connecting-wall, concrete is easy folder mud, when descending reinforcing cage
It is stained with mud on reinforcing bar, reduces concrete reinforcement bond stress, wall quality is difficult to ensure, and easily causes the random infiltration of metope
Water, this is cast-in-place ground-connecting-wall insurmountable problem always.
Third, degree of plainness for wall surface is not easy to control in soft stratum；When soil layer is weak or layer of sand, if mud conditioning is not
When cell wall has collapsing, it can be common that metope has the problems such as outer bulgy phenomenon, degree of plainness for wall surface is difficult to control.
Using complete prefabricated ground-connecting-wall, there are the following problems: first, component conveying is difficult；Due to complete prefabricated ground-connecting-wall length compared with
Greatly, the general narrower width of urban road, thus there are superelevation or cornering difficulties when being transported.Second, lifting is difficult in place
Control；Complete prefabricated ground-connecting-wall is larger due to being self-possessed, thus needs Large-scale Hoisting equipment, needs more wide lifting space, together
Shi Yinwei is overweight to be caused to finely tune difficulty in place.Third, seam waterproof are difficult to ensure；Complete prefabricated ground-connecting-wall is cold joint due to seam
Seam, and since construction error causes seam quality easiness to guarantee, therefore it is easy to cause seam crossing leak, influence structure construction.
