Bell-Mouth Spillways
喇叭口洩洪道
At first glance you might mistake a bell-mouth spillway for a
watery vortex into another dimension. What can only be
described as a giant hole in the water is actually a method
for controlling the release of flows from a dam or levee
into a downstream area. These spillways help prevent
floods from ‘dam’-aging or destroying a dam.
乍看之下,你可能會誤以為是鐘口洩洪的
水樣漩渦。其實這是一個
水中的巨孔用於控制從一個壩堤
流釋放到下游區的方法。
這些洩洪道有助於防止”壩”老化或洩出大壩的洪水。
A spillway is a structure used to provide for the controlled
release of flows from a dam or levee into a downstream area,
typically being the river that was dammed – Spillways release floods so that the water does not overtop
and damage or even destroy the dam. Except during flood periods,
water does not normally flow over a spillway – In contrast, an intake is a structure used to release water on
a regular basis for water supply, hydroelectricity generation, etc. – Floodgates and fuse plugs may be designed into spillways
to regulate water flow and dam height – Other uses of the term “spillway” include bypasses
of dams or outlets of a channels used during high water,
and outlet channels carved through natural dams such as moraines.
洩洪道是用於提供從一個壩堤流動的控制
釋放入下游區,是典型的河流被截流的結構。
-洩洪道釋放洪水使水不影響上層建築和損害甚至破壞水壩。
除了在洪水期間,水不正常流過洩洪道。
-另一方面,攝入量定期用來釋放供水,
水力發電等的結構。
-水閘和保險插頭可設計成洩洪道,
以調節水流量和壩高。
-”洩洪”的其他用途包括大壩旁路或
在高水的使用渠道網點,並通過天然水壩如雕冰磧出口通道。
– Some spillways are designed like an inverted bell so that
water can enter all around the perimeter.
These uncontrolled spillway devices are also called: morning glory,
plughole, glory hole, or bell-mouth spillways – In areas where the surface of the reservoir may freeze,
bell-mouth spillways are normally fitted with ice-breaking
arrangements to prevent the spillway from becoming ice-bound
-某些洩洪道被設計像倒鐘使水能夠在周邊所有輸入。
這些不受控制的洩洪裝置也被稱為牽牛花,
塞孔,或喇叭口洩洪道。
-另外,在儲存器的表面可以凍結區域
喇叭口洩洪道通常裝有破冰安排,以防止洩洪道變的冰冷結合。
