Connect, another part is stretched into the second stage of diaphram wall, and is connected by multiple setscrews with the second stage of diaphram wall, after connection
Sealing steel plate the seam between I-shaped steel joint and the second stage of diaphram wall is completely covered；It is coated with the outside of sealing steel plate
Waterproof mortar course.
The utility model preferably technical scheme：The height of the sealing steel plate is equal with the height of diaphram wall, thick
Spend for 4-8mm, width 350-500mm.
The utility model preferably technical scheme：The multiple setscrew uses model M20 setscrew, erects
To arrangement, and the spacing between two adjacent setscrews is 250-350mm.
The utility model preferably technical scheme：The waterproof mortar course is to smear 2-4cm after linked network on sealing steel plate
The coating that thick waterproof mortar is formed.
The beneficial effects of the utility model：
1st, the utility model is docked using closing steel plate measure in advance at the phase of diaphragm wall seam one and the second stage of groove segment interface
Seam weak location has carried out a reinforcement processing, effectively stops the harmful effect of outside Water And Earth Pressures abutment joint；
2nd, closing steel plate of the present utility model and waterproof mortar comprehensive function, effectively reduce diaphram wall seam position
The possibility for occurring infiltration leak again after excavation of foundation pit is put, adds safety coefficient during excavation of foundation pit；
3rd, construction of the present utility model can be constructed with earth excavation process, and the speed that it is installed is fast, work of constructing
Skill is simple, but positive effect.
