Navigation water area overwater construction safety risk early warning grading method and system

Abstract

The invention discloses a navigation water area overwater construction safety early warning grading method and system. The system comprises a core index data module, a real-time monitoring receiving module, a risk analysis module and a risk early warning module. The core index data module comprises a three-level safety index system unit and a user-defined safety index unit, and quantification of each safety index is based on national laws and regulations, industry specifications and experience of industry experts; the real-time monitoring receiving module is used for displaying the construction monitoring data of each safety index in real time and transmitting the monitoring data to the risk analysis module regularly; the risk analysis module comprises an actual measurement risk factor identification unit, a safety risk grade division unit, a single-index risk evaluation unit and a multi-index comprehensive risk evaluation unit, and is used for evaluating the safety risk degree of allfactors and the overall construction environment coupled with the multiple factors; and the risk early warning module displays the risk levels of the safety index factors and the comprehensive evaluation result and the corresponding safety measure suggestions to the construction personnel through the visual safety early warning platform, and is used for risk early warning.

Description

technical field [0001] The invention belongs to the field of early warning of construction risks on water, and in particular relates to a method and system for early warning and classification of safety risks of construction on water in navigable waters. Background technique [0002] The construction of my country's water transportation projects presents a development trend of complexity, large-scale, and deep water. Among them, on the one hand, the environment of the construction water area has become more severe; on the other hand, the overlap and proximity of the construction water area and the shipping route further increases the complexity of the water construction environment. Especially in water construction carried out in busy navigable waters, the interaction between sailing ships and large water construction equipment is constantly changing. [0003] The multi-dimensional and complex construction environment in navigable waters not only brings safety hazards that ...

AI Technical Summary

Problems solved by technology

However, at present, traditional construction ships generally lack real-time environmental monitoring methods for wind, waves and currents. Most of the environmental information comes from the long-term hydrology, waterway and other information collected for the construction area during the construction organization design stage. In the actual construction process Construction personnel mainly rely on weather forecasts to roughly assess conditions such as wind, waves, and currents during construction. There is no real-time and accurate monitoring method for the specific environment of a specific construction area.

Generally speaking, the existing environmental monitoring methods are insufficient, and the monitoring accuracy and timeliness cannot provide timely and effective information support for risk early warning during the construction process.

[0006] (2) There is a lack of grading criteria for water construction safety

[0007] Judging whether the facing environmental conditions meet the requirements of normal construction mainly includes the following two methods: one is to judge whether the facing environmental conditions meet the requirements of normal construction, mainly based on the construction conditions caused by single factors such as flow velocity and waves stipulated in industry specifications Whether it seriously affects the safety of the construction project. Once the degree of influence of a single factor seriously exceeds the limit allowable conditions, it is judged that the construction cannot be carried out normally under this working condition. , the single factor does not exceed the allowable range of the limit, but multiple conditions are in the situation that may bring safety hazards, it is impossible to judge the safety risk level of the overall construction environment in a complex environment considering multiple factors and whether it is satisfied according to industry standards. The conditions of normal construction; the second is to rely on the experience of the captain to comprehensively predict the safety risk level of the construction environment, but this method is obviously limited by the captain’s personal level and experience, and may underestimate the safety risk level of the overall environment and cause potential safety hazards Misjudgment in different ways, such as problems or overestimation of the degree of safety risk faced by construction, which leads to the reduction of construction efficiency, which in turn leads to accidents such as ship collision, equipment damage, and fire

[0008] (3) Insufficient risk warning measures

[0009] At present, the research on construction risk early warning measures mainly focuses on two aspects: ship navigation safety risk assessment and bridge (fan) and other specific project construction risk analysis. There are few studies on safety risk assessment of extensive water construction projects, especially for the navigation field. The establishment of a scientific and comprehensive safety technical index system and the research on mature safety risk early warning systems and methods are still lacking in water construction projects.
