Description
(54) ПЛОТИН А ИЗ МЕСТНЫХ МАТЕРИАЛОВ(54) DAM AND LOCAL MATERIALS
Изобретение относитс к гидротехнике, в частиости к строительству плотин из местных материалов .The invention relates to hydraulic engineering, in part to the construction of dams from local materials.
Известны плотииы из местных материалов с дренажной прослойкой и водоотвод щнм коллектором , расположенным на контакте материала плотины с основанием.Known flesh from local materials with a drainage layer and drainage schnm collector located on the contact of the material of the dam with the base.
Однако в таких плотинах фильтрацион:т ш поток , поступающий со стороны верхового откоса, проникает в низовой клин плотины и ее основание. However, in such dams filtration: the stream flow from the uphill slope penetrates into the downstream wedge of the dam and its base.
С целью обеатечени перехвата фильтрационного потока, поступающего со Стороны верхового откоса, дренажна прослойка в предлагаемой плотине размещена между пpoтиБoфильTpaциQHHЬпvffl опо ми, верх1шй из которых имеет длИну, меньше длины дренажной прослойки.In order to intercept the intercepting filtration flow coming from the uphill slope, the drainage layer in the proposed dam is located between the stretching profile of the QHHvvffl area, the top of which has a length less than the length of the drainage layer.
На чертеже изображена предлагаема плотина,поперечный разрез.The drawing shows the proposed dam, a cross-section.
Нлотина 1 выполнена из местных материалов. На контакте материала плотины и основани расположена дренажна прослойка 2 с водоотвод щим коллектором 3. Дренажна прослойка уложена с уклоном 2° в сторону низового откоса. Сверху и снизу дренажной прослойки размещены противофильтрационпые слои 4 и 5, причем верхний слой 4 Nlotina 1 is made from local materials. A drainage layer 2 with a drainage manifold 3 is located at the contact of the material of the dam and the base. The drainage layer is laid with a slope of 2 ° towards the lower slope. On top and bottom of the drainage layer are the filtering layers 4 and 5, with the upper layer 4
имеет длину,меньше длины дренажной прослойки 2 и нижнего сло 5.has a length less than the length of the drainage layer 2 and the lower layer 5.
Длина верхнего противофильтрацио1П4ого сло определ етс по формулеThe length of the upper antifiltration layer is determined by the formula
(0,8-l).(Hi+tb)(0.8-l). (Hi + tb)
где HI - напор в верхнем бьефе;where HI is the head in the upstream;
tfl - толщина верхнего противофильтрациониого сло .tfl is the thickness of the upper filter layer.
В процессе зкшлуатации плотины фильтрационный поток, поступающий со стороны верхового откоса, дренируетс открытой частью дренажной прослойки 2 и через водоотвод щий коллектор 3 отводитс за пределы плотин ; в приемный колодец 6.In the process of dam operation, the filtration flow coming from the uphill slope is drained by the open part of the drainage layer 2 and is diverted out of the dams through the drainage collector 3; in the suction well 6.
