Method and device for judging construction safety risks

Abstract

An embodiment of the invention provides a method and apparatus for researching and determining construction security risk. The method comprises the following steps: arranging an axis net in a three-dimensional scene, binding the axis net to a BIM model, binding the BIM model to a construction procedure, wherein the BIM model comprises a BIM model of a car station main body, a risk source BIM modeland a monitoring site BIM model; separately acquiring a risk source and a monitoring site from the risk source BIM model and the monitoring site BIM model, associating the risk source with the monitoring site and associating the risk source with a monitoring value of the monitoring site according to a number of the monitoring site; extracting a pit model from the three-dimensional scene with theaxis net, and associating the construction procedure with the pit model; and displaying a relationship between the BIM model associated with the pit model and the monitoring value according to an actual construction progress so as to research and determine the construction security risk, wherein the actual construction progress is associated with the construction procedure. By adopting the methodand apparatus for researching and determining the construction security risk, the monitoring value can be reasonably combined with the BIM model in real time, so that the security risk can be controlled and positioned according to the actual construction progress.

Description

technical field [0001] The embodiments of the present application relate to the technical field of construction safety, and in particular to a method and device for researching and judging construction safety risks. Background technique [0002] At present, the rapid development of urbanization has continuously stimulated the rapid growth of urban public transport. In the urban public transportation system, the subway is an important part, especially for the megacity public transportation system, the subway gradually becomes the backbone. [0003] The subway construction is a high-risk and technically complex project. Due to the objective and complex adverse geological conditions, the subjective unsafe behavior of the construction personnel, the surrounding environment, technology and other reasons, geological disasters and engineering accidents often occur. Occurrence will seriously endanger the safety of subway construction, lead to the delay of the construction period, a...

[0003] The subway construction is a high-risk and technically complex project. Due to the objective and complex adverse geological conditions, the subjective unsafe behavior of the construction personnel, the surrounding environment, technology and other reasons, geological disasters and engineering accidents often occur. occur, which will seriously endanger the safety of subway construction, lead to delays in the construction period, and increase cost consumption

[0004] In order to improve the safety management level of subway construction and avoid a series of adverse effects caused by safety issues, in recent years, relevant solutions have been provided in the prior art. However, in the solutions provided in the prior art, the on-site monitoring data and space The main model of the building structure in the region lacks real-time organic connections, which leads to the inability to control and locate safety risks along with the actual construction progress. The mechanism of safety risks is not clear, resulting in low risk management efficiency, high accident probability, and high construction costs. , the construction safety of rail transit is difficult to guarantee, and the economic benefits are difficult to maximize
