有关资料介绍,混凝土U形渠槽具有许多优点,主要的是输水能力较大,又比其它形式断面的等厚度衬砌省工、省料.但究竟U形渠槽比一般渠槽的输水能力大多少?衬砌工程量小多少?这是人们所关注的;本文对混凝土U形渠槽与矩形渠槽的水深.输水能力、衬砌工程量进行了比较,(矩形侧壁与底板整体浇筑且矩形槽与U形槽的衬砌厚度相同图1)经比较得出了如下的结论:U形槽的输水能力比矩形槽大不了多少,而衬砌工程量则减小得较多,其具体数据见图二.
Relevant information, concrete U-shaped channel has many advantages, mainly the larger water capacity, but also than other forms of equal thickness lining lining work, save material.However, U-shaped channel than the general channel of water What is the capacity? How much is the amount of lining work? This is of concern; this paper compares the water depth of concrete U-shaped channel and rectangular channel, the capacity of water delivery and the amount of lining work, And the same thickness of the rectangular groove and the U-shaped groove lining Figure 1) The following conclusions drawn from the comparison: The U-shaped groove is not much larger than the rectangular groove of the water transmission capacity, while the amount of lining works to reduce more, the specific data See figure two.
