Embodiment

[0013] A graded floating retaining dam consists of a concrete foundation 1, a cover plate 12, a water-filled rubber bag 3, a submersible pump 7, a steel support plate 6 and a flat gate 9. The concrete foundation 1 is a square excavated at the river bed Pit; the concrete cover 12 is buckled on the concrete foundation 1, and slotted at the corresponding position of the slab gate 9 to allow the gate 9 to rise and fall, the top of the cover 12 is level with the river bed, and the side wall of the concrete foundation 1 corresponds to the gate 9 position Vertical door slots 5 are respectively provided, and four thrust ridges 2 are respectively provided on the two side walls of the lower part of the cover plate 12 for supporting when the steel support plate 6 sinks in the square pit; four water-filled rubber The bag 3 is arranged in the channel between the concrete foundation 1 and the cover plate 12, and the water-filled rubber bags 3 are glued and connected to form a whole. A safety ...

Abstract

A grading lifting type retaining dam is composed of a concrete foundation, a cover plate, water-filling rubber bags, a sinking pump, a steel bracing plate and a plate gate. The concrete foundation is a square pit excavated in the position of a riverbed, the concrete cover plate is upturned on the concrete foundation and is slotted in the position corresponding to the plate gate, vertical gate slots are respectively arranged in side walls of the concrete foundation, the water-filling rubber bags are arranged in a cavity between the concrete foundation and the steel bracing plate, the water-filling rubber bags at the bottommost layer are provided with water inlet pipes and are connected with the sinking pump fixed on the upstream riverbed, each water-filling rubber bag is provided with a discharge pipe, and the steel bracing plate is arranged on the water-filling rubber bags; the plate gate is arranged in the gate slot and is provided with a main wheel and a reverse wheel, and P-type rubber water stop is arranged at the position where the plate gate is contacted with the concrete cover plate. The grading lifting type retaining dam has the advantages that water retaining height within the design scope of the retaining dam is controllable, and the dam is novel in structure, low in construction difficulty, prefabricated in construction, short in construction period, good in economic effectiveness and good in application prospect.

Description

Technical field [0001] The invention relates to a new design of a graded floating retaining dam, in particular to a graded floating retaining dam. Background technique [0002] At present, my country has many small rivers with small annual average flow, and these rivers often show a large difference in flow between wet and dry periods, showing significant flow unevenness and seasonality. Especially for seasonal rivers, the flow difference between flood period and dry period is very large. In the dry season, the flow of this kind of river may be only tens or even a few cubic meters, and sometimes the river may even dry up and the river bed will be exposed; In the wet season, the water flow increases sharply and even floods are caused by precipitation such as heavy rain and snowmelt. Therefore, this kind of river with hydrological characteristics has produced many unfavorable factors for the sustainable development of people's domestic water and ecological landscape within its inf...
