Because if the support from the end, that is, the root of the cantilever pouring, the cantilever is the front end of the pouring belt. After pouring pouring belt is bound to produce a bending stress of gravity, it may lead to the first place with a combination of cracks. However, if there is no such a back bend. Of course, the premise is the cantilever part of the template support structure reliability is guaranteed.
General joints are the final processing, in accordance with this principle, you can infer the front end (Yuan Duan) pouring, and finally deal with the old and new material seam problem
Causes of cantilever beam cantilever pouring from the beginning:
