The ninth step: the bridge potential safety hazard troubleshooting information management platform and the mobile APP terminal query are used for carrying out statistical analysis on the potential safety hazard of the bridge, checking the statistical analysis result according to the user permission and providing decision support for the project.
Shown in a matched manner of figure 3, the technical responsible person, the quality responsible person, all the supervision and management of the project construction unit and the owner member all have the authority of checking the statistical analysis result, the real-time state of the bridge potential safety hazard is counted in two modes of checking the information management platform through the bridge potential safety hazard, and the mobile APP terminal is used for inquiring, meanwhile, the statistical analysis can be carried out according to the time, the process, the potential safety hazard category, the cause, the rectification time limit, the construction progress, the potential safety hazard initiating unit and the like of the potential safety hazard, and the decision support is provided for the project.
The project initiates statistics of units according to the bridge potential safety hazard, the rectification time limit and the potential safety hazard, and the results are shown in a table 7.
As can be seen from table 7, the bridge substructure enters the construction state at first, the potential safety hazard ratio is the largest and reaches 39.84%, the number of potential safety hazards of the bridge superstructure and the bridge auxiliary facilities in the subsequent construction is obviously reduced, and the bridge potential safety hazard troubleshooting informatization management platform plays a key role; in the construction process of the bridge substructure and the auxiliary engineering, more than 80% of potential safety hazards can be corrected according to the schedule, and because the construction operation cross faces of the bridge superstructure are more, the number of the potential safety hazards corrected according to the schedule is only 67.4%; the construction unit of the project is a main initiating unit of beam potential safety hazards, and then a supervision unit.
The project is counted according to the category of the potential safety hazards of the bridge and the rectification period, and the result is shown in table 8 and fig. 4.
The bridge potential safety hazard troubleshooting informatization management platform has the characteristics of very intuitive data statistics, and can be seen from a table 8 and a graph 4: the probability of occurrence of potential safety hazards of different types of bridges in the project is different, wherein the adjacent edge protection and the temporary support system protection are the maximum potential safety hazards of the bridges, account for 22.65% and 19.14% respectively, and have serious problems of over-period rectification and modification; the probability of occurrence of the potential safety hazards of individual protection, temporary electricity utilization and special equipment protection is concentrated at 12.50% -15.63%, the potential safety hazards are the main potential safety hazards of the project, but only individual cases are regularly corrected, 1 case is not corrected after being regularly corrected, reasons need to be found out and the causes need to be properly processed; the safety hidden danger occurrence probability of the bridge scaffold protection, identification label and common equipment protection is less concentrated at 3.53-7.03%, but the phenomenon of over-period rectification exists, and related responsible persons need to timely develop the treatment of the hidden danger and ensure the quality of the treatment of the hidden danger.
The project edge-bound protection is counted according to the detailed safety hazard and the adjustment period, and the result is shown in table 9 and fig. 5.
The critical protection is the main potential safety hazard of the bridge, and the proportion of the details of the bridge is analyzed, as shown in the table 9 and the figure 5, wherein the deep foundation pit is not properly protected, is the main potential safety hazard and is the weak point which most easily causes personnel and property loss, and related persons responsible for the project are required to check the statistical result of the information management platform according to the bridge potential safety hazard, increase the capital and personnel investment in a targeted manner, and carry out construction operation under the condition of ensuring proper protection; the limb protection is equivalent to the easier operation of deep foundation pit protection, the problem of improper safety protection with a higher proportion still exists in a construction site, and related responsible persons of the project should strictly implement the correction and modification measures according to the statistical result of the bridge safety hidden danger investigation informatization management platform and take charge of the persons.
The statistical results of the project according to the construction progress and the finishing period are shown in table 10 and fig. 6.
In the project, the proportion of the potential safety hazard in three quarters in 2018 is 18.75%, the proportion of the potential safety hazard reaches the maximum value of 24.22% as the construction working face is expanded and 4 quarters in 2018, and as the bridge potential safety hazard troubleshooting informatization management platform is pushed forward and used, project group workers pay more attention to the prevention and treatment of the bridge potential safety hazard, and the quantity of the potential safety hazard is gradually reduced; in the third quarter of 2019, due to the influence of rainy seasons on construction, the potential safety hazard of the bridge slightly rises compared with that of the bridge in the last quarter; overall speaking, but with the use of the information management platform for bridge potential safety hazard investigation, the frequency of occurrence of bridge potential safety hazards is obviously reduced, and by 2020 one quarter, the bridge potential safety hazards only account for 3.91%.
In conclusion, the invention breaks through the bottleneck of traditional bridge potential safety hazard management, and forms three links of ' potential safety hazard acquisition, ' potential safety hazard rectification ' and ' potential safety hazard acceptance check ' involved in the bridge construction process into informationized and closed-loop management by relying on the BIM technology, thereby shortening the handling time of the bridge potential safety hazard and improving the potential safety hazard processing capability. Meanwhile, the invention converts two-dimensional information management into three-dimensional visual information management, and increases the extraction efficiency of bridge safety information in the bridge construction period. In addition, the method can automatically perform statistic analysis on the collected bridge potential safety hazard data to generate various types of potential safety hazard statistic graphs and statistic reports, so that the safety management of the bridge in the construction period is more targeted, and a manager is assisted to make a decision.
