Description
Technical Field
The utility model relates to a reduce box girder structure of low reaches stagnant water plane accident gate buoyancy support power belongs to hydraulic and hydroelectric engineering metal construction technical field.
Background
For the downstream water stop plane accident gate, because the bottom edge of the gate is positioned at the upstream side, the influence of bearing the water body buoyancy is large, sometimes the gate can not be closed due to insufficient closing force, particularly, the gate adopting a box-type main beam structure at the bottom is more prominent, because the distance between double webs of the box-type main beam is large, the water pressure difference between the double webs is large, the buoyancy force borne by the gate is large, the difficulty of closing the gate is large, therefore, the prior art is still not perfect, and the problem is to be further improved.
SUMMERY OF THE UTILITY MODEL
