Description
Technical field
It the utility model is related to a kind of diaphram wall as foundation pit stope support.
Background technology
When traditional foundation pit stope support uses diaphram wall, cast-in-place construction is generally all used, but deposit using cast-in-place construction
In problems with：
First, concrete uses cast-in-place construction, it is necessary to which time upper intensity, can just excavate, the overall duration after reaching some strength
It is long.
2nd, often there is dew muscle because collapse hole thickness of protection tier does not reach design requirement, tremie lifting is too fast
There is folder mud broken pile in concrete, while collapse hole often results in concreting excess, sugarcoated haws wall occurs, and concrete wastes serious.
3rd, cast-in-place diaphram wall needs the connector of the forms such as locking notch pipe, and technique is more complicated.
4th, steel reinforcement cage binding, concreting need a large amount of workers, can not realize industrialization.
There is coercion underground continuous wall in the problem of being directed to cast-in-place ground-connecting-wall in recent years, using stake cast-in-place concrete between wall
Mode connects adjacent two prefabricated ground-connecting-walls, and this mode is not the complete prefabricated ground-connecting-wall in complete meaning, if adopting
During with pure prefabricated mode, due to being entirely limited the free degree of wall width, construction environment is required it is high, in practice of construction very
Hardly possible is realized.
Utility model content
The purpose of this utility model is to provide a kind of ladder type prefabricated diaphram wall, to solve existing ground-connecting-wall construction and exist
