There is following two in method, first problem is to squeeze the clear distance between sleeve often since extruding tonger size is larger
Smaller, operation can not be protruded by squeezing tonger；It is point-by-point flattening sleeve that Second Problem, which is due to squeezing tonger, until sleeve is along long
Degree direction is crushed entirely, and the Connection Time is quite very long.
In summary, it connects along the immovable concrete prefabricated element of reinforcing bar axis direction, still belongs to fast and reliablely
The blank field urgently filled up.
