Description
Technical field
The present invention relates to Hydraulic and Hydro-Power Engineering metal structure technical field, and in particular to a kind of extra-high head planar slide lock
The improved method and structure of door.
Background technology
For extra-high head planar slide gate, one sealing, downstream forward direction both sides arrangement two are arranged using downstream generally
The main supporting type of row slide block, this is present, and the forward and reverse only left and right sides of gate is spacing, and gate easily produces vibration during Xiamen,
And the edge of a wing is generally broken line mutation structure after planar slide gate upstream face plate or bottom girder, the fluidised form of current can be caused disorderly,
Active force of the increased water flow to gate, therefore radial gate vibration is also easily induced, increased the difficulty of the dynamic water blockage door of gate；In addition,
It is without supporting for an elongated gerber beam at the top of gate, weaker with respect to boundary beam rigidity, in the case where extra-high head is acted on, meeting at the top of gate
Downstream there is larger skew in side, causes top seal compression excessive and destroys, and drainage occurs, and affect the sealing of gate
