Изобретение относитс к гидротехническим сооружени м и предназначено , преимущественно дл забора воды из равнинных участков рек, транспортирующих обильное количество донных наносов.The invention relates to hydraulic structures and is intended primarily for withdrawing water from lowland sections of rivers transporting abundant amounts of sediment.
Известно водозаборное сооружение, .включающее криволинейное подвод щее русло, водосбросное сооружение и криволинейную дамбу 1.,QA water intake structure is known, which includes a curvilinear supply channel, a water discharge structure and a curvilinear dam 1., Q
Известно также водозаборное сооружение , включающее криволинейное подвод щее русло, водосбросное сооружение и водоприемник с порогом 2.It is also known a water intake structure, including a curved supply channel, a water discharge structure and a water intake with a threshold 2.
Такие сооружени удовлетворительно is работают лишь при Q, а при Q. происходит отложение крупных фракций наносов перед подоприемником, где Q - расход воды в русле.Such facilities satisfactorily work only at Q, and at Q. large sediment sediments are deposited in front of the reservoir, where Q is the flow of water in the channel.
Цель изобретени - повышение надеж-20 ности работы сооружени за счет уменьшени осаждени наносов в верхнем 6be(J)e и уменьшени размыва нижнего бьефа.The purpose of the invention is to increase the reliability of the operation of the structure by reducing sediment deposition in the upper 6be (J) e and reducing the erosion of the lower reach.
Поставленна цель достигаетс тем, что порог выполнен с откосом, лини пересечени которого с дном верхнего бьефа описана синусоидой ; ,13 В si пх, точка перегиба которой расположена на оси водоприемника на рассто нии 4h от порога, где В ширина водоприемника; h - высота порога .The goal is achieved by the fact that the threshold is made with a slope, the line of intersection of which with the bottom of the upper pool is described by a sinusoid; , 13 B si nx, the inflection point of which is located on the axis of the receiving water at a distance of 4h from the threshold, where B is the width of the receiving water; h - threshold height.
На фиг, 1 изображено водозаборное сооружение, вид сверху; на фиг. 2 схема построени откоса порога.Fig, 1 shows a water intake structure, a top view; in fig. 2 is a scheme for constructing a slope of a threshold.
Водозаборное сооружение включает криволинейное подвод щее русло 1, водосбросное сооружение 2, водоприемник 3 со сложным криволинейным в плане порогом 4 переменного откоса.The water intake structure includes a curvilinear supply channel 1, a water discharge structure 2, a water intake 3 with a complex curvilinear in terms of threshold 4 of variable slope.
Предлагаемый сложный криволинейный в плане порог переменного откоса строитс как показано на фиг. 2. Опытноэкспериментальным путем получают оптимальную форму порога в плане, описываемую синусоидой ,13 Вsin X, где В - ширина водоприемника.The proposed complex curvilinear threshold of a variable slope is constructed as shown in FIG. 2. Experimentally, an optimal threshold form in the plan is obtained, described by a sinusoid, 13 B sin X, where B is the width of the receiving water.
