Bridge-erecting and bridge-laying units must take effective measures to strengthen publicity and education, so that workers can realize the important position of bridge erecting machine in railway construction and know that their work greatly affects whether the railway can be completed on schedule, which is related to the safety of life and property of the country and people. Let the workers love their jobs from the bottom of their hearts and be dedicated to their posts. Leaders at all levels and all employees should bear in mind General Secretary Jiang's instructions that "hidden dangers are more dangerous than open flames, prevention is better than disaster relief, and responsibility is more important than Mount Tai", and also bear in mind that "sleepless nights" cannot be grasped safely, so as to enhance safety awareness and responsibility awareness.
2, the implementation of safety system engineering, the implementation of comprehensive safety management.
It is necessary to fully implement the safety system engineering in enterprises, find the hidden dangers of the construction system, predict the harm caused by faults and mistakes, design and apply safety measures, organize the implementation of safety measures, summarize and evaluate the effects of measures, and constantly improve the construction system.
Total safety management refers to the application of system engineering principles, comprehensive application of modern management techniques and methods, the implementation of the whole process of safe production and the management of all employees involved in all the work. In this way, it can be woven into a crisscross safety management network, which is vertical to the end and horizontal to the side, so that all safety management work of enterprises can form an organic whole. Total safety management is the most fundamental and effective organizational management method for enterprises to do a good job in safe construction and production.
Offline construction units and bridging units should formulate specific safety management systems and implement them effectively in accordance with the principles and requirements of safety system engineering and comprehensive safety management.
The management system should focus on the whole system of engineering, equipment and people, from the preparation of construction organization plan to the completion of bridge erecting machine, from the design and manufacture of bridge erecting machine to the use and maintenance of bridge erecting machine, from the general manager of bridge erecting project to the person in charge of subgrade construction and machinery to earthwork and bridge erecting machine operators.
3. Strengthen the training of workers and strictly implement the Rules for Erection of Railway Bridges.
Girder erection work includes public works, maintenance, electric power, vehicles, transportation and other aspects, and any operator's operational mistakes will lead to accidents. All employees should be trained in an organized way. In the training process, we should not only pay attention to practical skills, but also pay attention to theoretical knowledge, so that all employees can master the relevant knowledge and skills skillfully, so that they have a high level of operation and strong adaptability. The Rules for Girder Erection of Railway Bridge Erection Machine has strict regulations on bridge erection. As long as it is strictly implemented, the overturning accident of bridge erecting machine can be greatly reduced. Therefore, the bridging unit should organize relevant personnel to study the rules comprehensively, be familiar with every detail, learn from the accidents that have happened, and prevent similar accidents from happening again. The system of working with certificates is implemented, and all personnel must pass the training examination and obtain corresponding certificates before they can work, and they are trained regularly to update their knowledge.
4, scientific formulation of time limit for a project
At present, many construction enterprises have used network planning technology to make reasonable arrangements for the duration and progress of the whole project. Through network optimization technology, the start time, start sequence of each subproject and the whole duration of the whole project have been arranged most scientifically and reasonably. If all construction units reasonably apply this technology (not just superficial for bidding), arrange the construction period scientifically and reasonably, link the progress and quality of each subproject with the immediate interests of employees in the implementation process, and have clear rewards and punishments measures to ensure the construction quality and progress, they can win enough time for paving units to complete the paving task with good quality and quantity. Don't shorten the construction period again and again for the sake of "giving gifts", so as to ensure that there is enough construction period for bridge-laying, so that the bridge-laying personnel can track the bridge energetically according to the normal working system and eliminate the hidden dangers of accidents.
5. Strictly implement the supervision system to ensure the engineering quality.
The Code for Girder Erection of Railway Bridge Erection Machine requires that the construction unit of off-line engineering must provide the bridge-laying unit with information on the compaction of bridge-head fill, which is based on the fact that when the bridge-erecting machine overturns in recent years, it is mostly caused by the problem of bridge-head fill. For example, whether there are riprap, frozen soil block and non-layered rolling in the bridge head fill. Only the construction unit of the offline project knows best, and it can't be found out only by the inspection of the bridge laying unit.
However, in practice, the bridge-laying and bridge-erection units often disdain the information provided by the construction units of offline projects, because for a long time, the quality inspection and evaluation determined in the Railway Subgrade Inspection Standard in China is based on self-inspection. Self-inspection is normal as an internal management method, but as a project delivery, it is worth studying whether it is appropriate based on the results of self-inspection. In order to urge and check the construction units to strictly implement the technical standards of railway engineering, standardize the engineering quality inspection and evaluation standards issued by the state and the Ministry of Railways, strictly implement the engineering supervision system in railway subgrade construction and strengthen the engineering inspection work. All items that need to be inspected must be carried out in the presence of the supervision engineer, otherwise it will not be recognized. The previous procedure must meet the quality standards before the next procedure can be constructed. Only in this way can we ensure the quality of subgrade construction and eliminate hidden dangers of subgrade; Only in this way, the information provided by the offline project construction unit is true and credible.
In the construction of the bridge erecting machine, we should also strictly implement the supervision system, urge the bridge erecting machine units to strictly implement the provisions of railway bridge erecting machine, strictly implement the ballast regulations, operate and use the bridge erecting machine in strict accordance with the operating rules of the bridge erecting machine, and strictly implement the safety work regulations to ensure the erection quality and safety of the bridge erecting machine.
6, do a good job of equipment maintenance.
A perfect maintenance system should be established for bridge erecting machine. There are strict management methods from installation, commissioning, operation, warehousing, storage and other links, so that the bridge erecting machine is always in a good technical state. In addition, the condition monitoring and fault diagnosis of the bridge erecting machine should be strengthened to ensure the safe operation of the bridge erecting machine.
