1, preface
At present, there are a large number of hydropower stations in China, many construction participants, long engineering front, complex construction technology and many aerial work, which bring a lot of troubles and difficulties to the normal construction of hydropower stations. At the same time, due to the unique particularity of its construction, many safety hazards have been buried in the construction of hydropower stations.
2. Hidden dangers of safety management in hydropower station construction.
Because of its unique construction characteristics, hydropower station has brought many difficulties to the normal construction of hydropower station, and also laid many hidden dangers for the safety of hydropower station. A little carelessness will bring irreparable losses. Main problems in safety management of hydropower station construction;
2. 1 The correct safety management consciousness was not established in the early stage of construction.
In the early stage of hydropower station construction in China, it is necessary to open holes, drain and excavate the engineering roads and pools for hydropower station construction. A large number of blasting tools will be used for this work. Due to the lack of understanding of blasting tools in the early stage of construction, the choice of blasting work by the staff may not meet the needs of the geology around the hydropower station. Or because I didn't have enough buying knowledge, I bought fake powder. In this regard, the life safety of blasting workers is seriously threatened.
At the same time of blasting operation of hydropower station, high slope will gradually form during construction. Construction workers generally use large scaffolding to support high slopes. However, with the deepening of the project progress, the difficulty coefficient of supporting work is getting bigger and bigger, and the builders have no correct understanding of the preparatory work for hydropower station construction. Perfect preparation often leads to the collapse of scaffolding during construction, which greatly threatens the safety of construction workers.
2.2 the lack of a sound concrete pouring safety management system
After the initial excavation, the hydropower station began to gradually transfer to the later concrete pouring. When pouring concrete, cross operation is generally adopted, and the traffic task is heavy. Because the dam of hydropower station is getting higher and higher, cranes often work at high altitude, which greatly increases the risk factor of concrete pouring. At the same time, because the hydropower station has not established a perfect concrete pouring safety management system, it is impossible to ensure the safe use of construction scaffolding during construction.
3. Establish perfect safety management measures for hydropower station construction.
The establishment of hydropower stations in China has laid a more solid foundation for the utilization of national energy and played a great role in the growth of national economy. Establishing perfect safety management of hydraulic structures will surely become the focus of hydropower station management in China.
3. 1 Attach importance to the safety management of hydropower stations
There are many safety problems in hydropower stations, such as personnel operation, organization and construction design, unpredictable natural disasters, etc., which threaten the construction safety of hydropower stations all the time. Only by establishing a correct awareness of safety management, keeping safety management in mind, taking safety management as everyone's responsibility and attaching great importance to it can we minimize the occurrence of safety. In the process of safety management of hydropower stations, hydropower station management departments should vigorously publicize the safety prevention work of hydropower stations and truly implement the responsibility system.
3.2 Strengthen the safety management of blasting tools
Blasting plays an important role in the initial excavation of hydropower station. Strengthening the safety management of blasting tools is conducive to ensuring the life safety of hydropower station construction personnel and a good construction environment. In the procurement of blasting work, the hydropower station should select professionals who have a certain understanding of blasting tools for procurement, and do a good job in the transportation and storage of blasting tools. Establish a ledger to register the model, performance and quantity of the purchased blasting tools, and strictly check and accept them after warehousing. At the same time, record the collection of blasting tools, collect blasting tools in strict accordance with the specified quantity, and do a good job of fire prevention in the warehouse to ensure the storage safety of blasting work.
3.3 Strengthen the safety management of aerial work.
At the same time of concrete pouring in hydropower station, the dam body is getting higher and higher, and aerial work often occurs during construction, which seriously threatens the life safety of construction personnel. The construction management department of hydropower station should do a good job in the safety management of aerial work, hang the safety protection net as required during the construction process, and do a good job in plugging the temporary holes in the dam body to ensure that the construction personnel wear the construction safety protection tools correctly when working at altitude, so as to ensure the personal safety of aerial work.
3.4 Improve the skills and quality of employees
The safety of hydropower station construction is closely related to the skills and quality of hydropower station construction personnel. Many hydropower station accidents are closely related to the accidents caused by the low skills and quality of front-line staff. When selecting hydropower station staff, we should do a good job to ensure the professional quality of the staff, and at the same time train the hydropower station staff regularly to establish a talent pool. At the same time, the safety management department should strengthen the selection of safety awareness of front-line workers and standardize the skills and safety awareness of front-line operators from various aspects.
3.5 Conduct assessment competition.
Conduct regular safety knowledge examination competitions for all employees of hydropower stations, and incorporate the assessment results into the assessment of year-end bonuses. Publicize the importance of safety knowledge and the reward and punishment system of the examination, so as to gain the attention of all employees. From the point of view of hydropower station, all employees are forced to realize the importance of safety management and construction safety. At the same time, it is also a powerful means to motivate and restrain employees in the form of direct linkage between assessment and performance pay.
4. Conclusion
Ensuring the safety of hydropower station construction is an important issue in hydropower station construction and an important responsibility of hydropower station construction management department. In the safety management of hydropower station construction, we should clearly establish safety management norms, strengthen safety management means, raise the awareness of safety management of the whole people, and adopt practical and effective safety management methods to curb safety accidents in hydropower station construction. Strive to make the construction safety management of hydropower station truly move towards a brand-new future through the joint efforts of all personnel of hydropower station.
