Dike closure method based on whole assembly type double-culvert closure bottom structure

The present application belongs to the technical field of water conservancy and hydropower engineering closure construction, and particularly relates to a kind of embankment closure method based on integral assembly type double ridge closure bottom protection structure.The present application precast and accurately throw the integral bottom protection structure formed by rigid connection of bottom protection section and double ridge section in dry season of a year before closure, with standardized reinforced gabion as basic unit, adopt double connection inside and outside to form continuous plate type whole, with high impact resistance and stone blocking foot capacity.Through particle size and impact distance calculation, throw test, GPS joint positioning to realize accurate underwater throwing.After bottom protection construction is completed, embankment pre-advance is implemented in dry season of next year, and large stone and reinforced gabion are continuously thrown in closure stage, which can improve the stability of throwing material, prevent embankment collapse, and realize safe and rapid closure.The present application can solve the problems of traditional dispersed bottom protection, such as easy loss, low precision, interference with flood discharge, etc., and greatly improve the safety and efficiency of closure under complex riverbed conditions.

Methods and systems for intelligent gate systems that link groundwater and river / lake ecological water levels

ActiveCN121680090BIncrease guarantee rateImprove adaptabilityAdaptive controlHydrometryStream flow
This invention provides a method and system for intelligent gate control of groundwater-river / lake ecological water levels. The method includes: acquiring target data collected in real time through a sensing layer; the target data includes surface water level and flow data, groundwater level data, and meteorological data; using a coupled hydrological model in the decision layer, based on the target data, rolling predictions of the state changes of surface water and groundwater under different gate opening scenarios within a future set time period; based on the predicted state changes and preset ecological control targets, optimization calculations are performed through an intelligent control algorithm in the decision layer to generate an optimal gate opening command; the optimal gate opening command is sent to the execution layer to drive the gate to adjust to the target opening, and the actual gate opening is obtained for feedback. In this method, the rolling optimization of gate opening through a coupled hydrological model and intelligent algorithm improves the ecological flow guarantee rate and effectively enhances the ecological protection level and system adaptability.

An eco-hydraulic channel device with adaptive water and sediment rhythm and its usage method

ActiveCN120967878BIncrease guarantee ratereduce sedimentationHydrometryWater use
This invention provides an eco-hydraulic channel device and its usage method that are adaptive to water and sediment rhythms. The aim is to regulate sediment deposition in lakeside wetlands, ensure ecological water use, improve water quality, and restore the ecosystem by constructing a channel device and intelligent management system adapted to the hydrological rhythms of lakes. The device includes an inlet section (containing a narrow / deep / shallow-wide cross-section and permeable dikes), an ecological overflow section (divided into shallow habitat zones, surface flow purification zones, and deep pool conservation zones), a sediment interception system (prefabricated triangular cones and sedimentation tanks), and an intelligent management unit (water quality monitoring, water level sensing, and automated control modules). This invention can significantly improve the ecological water level guarantee rate of lakeside wetlands, reduce sediment deposition, enhance the self-purification capacity of water bodies, enrich biodiversity, and is suitable for lake ecological restoration projects.
