Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of construction management, and particularly relates to a water conservancy construction project management system based on data analysis. BACKGROUND
[0002] Water conservancy construction projects often involve complex hydrological conditions, such as the influence of river flow rate, water level fluctuation and rainfall, which have a direct and significant impact on construction progress, resource allocation and construction safety. However, existing water conservancy construction project management systems still have the following technical bottlenecks in dynamically responding to changes in water flow, weather changes and construction progress coordination:
[0003] Current water conservancy construction management mostly relies on traditional monitoring equipment to collect water flow and weather data, and the data is scattered and lacks intelligent integration. In particular, in complex construction areas, key parameters such as water level, flow rate and flow cannot form a comprehensive and real-time dynamic monitoring network, making it difficult for managers to timely perceive sudden changes in water flow and their potential impact.
[0004] The specific impact of water flow changes on construction progress and construction stages is often ignored. Most current systems separate water flow management from construction scheduling, lacking a model that can quantify the dynamic impact of water flow changes on construction plans. This disconnection leads to construction delays and safety risks.
[0005] Traditional water flow management methods are usually based on static construction plans and lack flexibility and adaptability. In the event of severe water flow changes (such as during flood periods or heavy rainfall), existing systems' drainage equipment or water flow regulation equipment cannot intelligently adjust based on real-time monitoring data, often requiring manual intervention, which is time-consuming and inefficient, and may even cause greater safety hazards.

The data analysis based water construction project management system as claimed in claim 6, wherein, The adaptive water flow regulation module is based on D s and R s determining target priorities and classification decisions, the target priority determination comprising: If R s >3: Take security measures to reduce the direct impact of water flow on the construction area; If D s > 30% and R s ≤ 3: Prioritize reducing the resistance of the drainage system or optimizing the direction of water flow with the goal of ensuring construction progress.
8. The data analysis based water construction project management system as claimed in claim 7, wherein, The classification decision specifically includes: D s ≤10%, R s ≤1, low impact: i.e. the water flow change has no significant impact on the construction, the current water flow management device operational state is maintained; 10% < D s ≤ 30%, 1 < R s ≤ 3, moderate impact: then partially optimize the drainage system or adjust the water flow direction, reducing the potential impact; D s >30% or R s >3, serious impact: overall adjustment of the flow direction of the construction area, adjustment of the water flow management equipment, and priority protection of construction safety.
