I would like to present a maintenance request report
for the tunnel boring machine (TBM) repair. Recently, we have encountered some issues with the TBM, and it is
crucial to address these problems promptly to ensure the smooth progress of our project.
Firstly, one of the major issues we have been facing is the malfunctioning of the TBM's cutting tools. The cutting tools are responsible for excavating the tunnel, and any malfunction can significantly impact the efficiency and progress of the project. For example, during the last excavation, we noticed that the cutting tools were not able to effectively break through the rock formations, resulting in delays and increased costs. This issue needs to be addressed urgently to avoid further disruptions to the project timeline.
Secondly, there have been frequent breakdowns in the TBM's hydraulic system. The hydraulic system is essential for the proper functioning of the TBM, as it controls the movement of various components. The breakdowns have led to unexpected downtime and increased maintenance costs. For instance, just last week, we had to halt the excavation for an entire day due to a hydraulic system failure. This not only impacted our progress but also caused additional expenses for repairs. It is crucial to resolve these recurring breakdowns to ensure uninterrupted operation of the TBM.
Furthermore, we have noticed a decline in the overall performance of the TBM's ventilation system. The
ventilation system is responsible for maintaining a safe working environment for the operators by removing dust and fumes generated during excavation. However, recently, we have observed that the ventilation system is not
efficiently removing the dust particles, leading to poor
air quality inside the tunnel. This poses a significant
risk to the health and safety of the workers. It is essential to address this issue promptly to ensure a safe
working environment for everyone involved in the project.
In addition to these specific issues, we have also noticed a general decline in the TBM's overall efficiency and productivity. The TBM is not achieving the expected excavation rates, resulting in delays and increased costs. This decline in efficiency can be attributed to a combination of the aforementioned issues, as well as the general wear and tear of the machine. It is crucial to conduct a thorough inspection and maintenance of the TBM to identify and resolve any underlying problems that may be affecting its performance.
In conclusion, the maintenance request report
highlights the issues we have been facing with the TBM, including the malfunctioning cutting tools, frequent breakdowns in the hydraulic system, decline in the ventilation system's performance, and overall decline in efficiency. It is imperative to address these issues promptly to ensure the smooth progress of our project and the safety of our workers. We request immediate attention and action to resolve these problems.

我想提交一份关于掘进机维修的请示报告。

最近，我们遇到了一些掘进机的问题，必须及时解决这些问题，以确保项目的顺利进行。

首先，我们面临的一个主要问题是掘进机切割工具的故障。

切割工具负责挖掘隧道，任何故障都会严重影响项目的效率和进展。

例如，在最近的挖掘过程中，我们注意到切割工具无法有效地突破岩石层，导致延误和成本增加。

需要紧急解决这个问题，以避免进一步影响项目进度。

其次，掘进机的液压系统经常发生故障。

液压系统对掘进机的正常运行至关重要，它控制着各个部件的运动。

故障导致意外停机和维修成本增加。

例如，就在上周，由于液压系统故障，我们不得不停止挖掘整整一天。

这不仅影响了我们的进度，还导致了额外的维修费用。

必须解决这些频繁发生的故障，以确保掘进机的连续运行。

此外，我们注意到掘进机的通风系统的性能下降。

通风系统负责通过排除挖掘过程中产生的灰尘和烟雾，为操作员提供安全的工
作环境。

然而，最近我们观察到通风系统无法有效地清除灰尘颗粒，导致隧道内空气质量较差。

这对工人的健康和安全构成重大风险。

必须及时解决这个问题，为项目中的每个人提供安全的工作环境。

除了这些具体问题之外，我们还注意到掘进机的整体效率和生
产力下降。

掘进机未能达到预期的挖掘速度，导致项目延误和成本
增加。

效率下降可以归因于上述问题的综合影响，以及机器的一般
磨损。

必须对掘进机进行彻底的检查和维护，以确定并解决可能影
响其性能的潜在问题。

总之，维修请示报告强调了我们在掘进机方面遇到的问题，包
括切割工具故障、液压系统频繁故障、通风系统性能下降以及整体
效率下降。

必须及时解决这些问题，以确保项目的顺利进行和工人
的安全。

我们请求立即关注并采取行动解决这些问题。
