Second ground wall of two flange plates and the second web structure, to form the cavity.
In specific implementation process, and then each groove segment vertically hangs prefabricated ground wall into trough end and enters slot peace later
It puts.Ground wall contiguous prefabricated simultaneously is hung successively after grooving is good.Chute forming machine into an adjacent groove segment should be put into it is pre-
The connection structure of system keeps certain safe distance, in order to avoid collision connection structure, in principle should with first hanging concave joint wall, then
With hanging convex joint wall, convenient for coercion underground continuous wall degree control, intermediate closed width answers first grooving to hang, and avoids grooving
Cumulative errors phenomenon occurs, and makes finally to be closed width and is difficult to transfer, and connector connects and is difficult to operate.
S12：To the second flange plate, the first flange plate, the first web structure and the second web structure outside the cavity
At least one of drill.After drilling, it may also include：Borehole cleaning processing is carried out to the hole drilled out.I.e.：Before casting concrete
Borehole cleaning is carried out, can reduce influences connector concrete quality because the mudcake of hole wall is mingled with, and avoids cold seam folder mud that percolation phenomenon occurs.
S13：Above step is repeated, until required ground wall and its connection structure completes above step.
S14：Casting concrete, to form diaphram wall.Specifically, the rising pouring of wall side wall can be starched by compaction grouting,
Gap filling between wall and cell wall increases frictional resistance.
In addition, carry out meeting the continuous welding of steel plate on the inside of pitted surface in Excavation Process, so as to form reliable steel
The multi layer waterproof of plate and concrete.
In conclusion diaphram wall connection structure provided by the utility model and the construction method of diaphram wall, lead to
It crosses two first flange plates and forms a concave space towards second ground wall with first web structure；And
Cavity is formed between second flange plate and the first web structure so that is formed between steel plate and is closed section, poured on this basis
The splice cavity concrete built, can form reliable steel plate and concrete multi layer waterproof, effectively improve infiltration energy, together
When, since the utility model also has the advantages of easy to control the quality, easy construction.
Finally it should be noted that：The above various embodiments is only to illustrate the technical solution of the utility model rather than it is limited
System；Although the utility model is described in detail with reference to foregoing embodiments, those of ordinary skill in the art should
Understand：It can still modify to the technical solution recorded in foregoing embodiments either to which part or whole
Technical characteristic carries out equivalent replacement；And these modifications or replacement, this practicality that it does not separate the essence of the corresponding technical solution are new
The range of each embodiment technical solution of type.
