1. No problem of cutting corners: The results of the survey show that there is no problem of cutting corners on the Lai Rong high-speed railway. For the problem that the length of some threaded pile construction piles does not meet the design standards, it is found that the results of encrypted geological exploration of this section of the road foundation show that the length of the threaded pile construction piles coincides with the height change of the bearing layer, although the length of some piles does not meet the design standards, but it has entered a better bearing layer, and no corners have been found. This result shows that the construction quality of the Lai Rong high-speed railway has not been affected.
It is worth mentioning that the continuous dynamic monitoring results of the whole line of the Lairong high-speed railway also prove the safety, reliability and stability of the project. According to the test data, the Lairong high-speed railway meets the 350 km-hour high-speed railway operation standard, the track smoothness meets the requirements, and the high-speed train can maintain safety and stability during operation.
2. No impact on the safety of the project: In the case that some people question that the pile length of the Lairong high-speed railway does not meet the design standards and may have an impact on the safety of the project, the survey results show that the stability and settlement of the road section before and after construction meet the requirements of the relevant railway codes, so it will not have an impact on the operation safety of the railway. At the same time, the joint investigation team also found that the acceptance results of the whole line of the Lairong high-speed railway showed that it met the safety and stability requirements of high-speed train operation.
3. Problems exist in engineering design changes and construction management: However, the survey also revealed that there are some problems in engineering design changes, construction management and project subcontracting of the Lai Rong high-speed railway. For example, in the construction process, there are indeed some sections of granite piles that cannot be completely driven, and the design changes should be carried out according to normal conditions, but the construction party did not make changes, but directly discussed with the supervision unit and the design unit and announced the completion. Although there are some deficiencies in the construction process of the entire Lai Rong high-speed rail project, it will not affect the safety and quality of the project as a whole.
The credibility of the findings is positive. The joint investigation team jointly formed by the State Railway Administration and Shandong Province has a high degree of authority, and the investigation team has a large number of members, and the entire investigation process has been verified by many parties, so that the construction party can not carry out any manipulation. In addition, if the construction party dares to falsify, it will bear heavy responsibility. Therefore, the results of the survey can be trusted, which shows that although the construction party does not meet the design standards, the pile length does not have an impact on the safety and quality of the project.
Some netizens may have expressed doubts about the fact that the survey results claimed that there was no cutting corners. After all, during the construction process, if the pile length does not meet the design requirements, whether the excess part is settled according to the normal **, does this also count as cutting corners?For example, the pile length requirement for some road sections is 30 meters, but due to special circumstances such as granite, the construction party only needs to finish 20 meters, which is equivalent to 10 meters less construction, which is not cutting cornersHowever, from an engineering construction point of view, this situation is not a case of cutting corners. In the process of producing pile lengths, the construction is carried out according to the design standards. Assuming that the design calls for a pile length of 30 meters, then this length needs to be driven during production. However, if the granite and other piles cannot be driven down during the construction process, only 20 meters can be driven, and the extra 10 meters will be truncated, because the tailings are no longer useful. The material used for the entire project is still maintained at 30 meters. Therefore, on the whole, although the pile length of some road sections does not meet the design standards, as long as the safety indicators of the design are met, they are qualified and do not belong to cutting corners.
In short, the investigation results of the Lairong high-speed railway show that there is no problem of cutting corners in the project, and it does not affect the safety and quality of the project. The survey also revealed problems in design changes, construction management, and subcontracting. However, this does not mean that the entire project is not credible and secure. At the same time, as readers, they should think rationally about the content of the report and have an objective understanding of the details in the construction of the project. Through the conclusions of the survey, we can expect that the Lai Rong high-speed rail will provide passengers with a more convenient, safe and comfortable travel experience.
