Safety assurance measures for the hottest stringin

Safety assurance measures for stringing construction

Enron is the most primary and fundamental demand of mankind. Enron production is not only the guarantee of people's life and health, but also the foundation of enterprise preservation and growth. As a key project to strengthen the power layout in Liupanshui area and meet the demand of increasing power load, the 220kV line project from Shannipo hydropower station to faer substation needs safe production to protect the convoy. The tightening line project involves a wide range of work staff, more air work, and a large number of insecurity. It is also the last divisional project. Therefore, the task of strengthening Enron prevention is particularly primary These measures are hereby formulated in order to do a good job in safe and civilized construction and achieve the overall goal of safe and sound construction. All construction teams are expected to seriously study, strictly control safety during construction, resolutely implement the goal of "safety first, prevention first", successfully complete the construction task of tightening the line, and complete the standard production

1. In order to ensure the smooth stop of the stringing construction, the safe method of care must be strictly implemented in all procedures of stringing

2. The Enron measures in this chapter include two parts: (1) Enron system. Its content mainly stipulates the duties of the sentry boxes and legal staff for tightening the line. (2) Enron technology method. Its content mainly stipulates the procedures of tightening the line and the matters that should be performed in the operation of various methods

3. The primary content of this chapter is compiled according to the "power support Enron task specification (overhead power lines)"

4. In order to effectively prevent the occurrence of accidents, the following three laws should be followed: (1) follow the construction organization law. Be clear about the division of labor and listen to instructions for all actions. (2) Follow the rest rule. The overall controllability of the sentry box task is strengthened by adhering to the sentry box, concentrating and conscientiously completing the cost. (3) Follow the rest rule. Insist on doing things according to regulations and standards, insist on construction according to design drawings, and insist on operation according to process design. The "procedures and standards" mentioned here refer to the

Enron procedures and acceptance standards. The process design here refers to the construction process design and technical methods compiled for the project

5. While implementing this Enron method, we must implement the "provisions on the handling of electric power support Enron construction"

6. Before stopping the stringing construction, the technical person in charge of each construction team and the construction person in charge should organize all construction staff to stop the same study of the Enron method, the "task specification of electric power support Enron" and the "Regulations on electric power support Enron construction management", and establish the understanding of Enron construction in a stable way. The construction person in charge should seriously teach the construction staff the important matters and operation methods of Enron, And do a good job of Enron custody

1. The safety production goal of "safety first, prevention first" must be implemented in the construction of tightening line

2. The main tools and instruments for stringing shall be suitable for the technical inspection standard, and attached with the useful load mark; Before use, the external inspection must be stopped. Unqualified people are strictly forbidden to use it, and it is really not allowed to take a small lead

3. Various anchor piles should be laid according to the technical regulations, and the specification and buried depth should be determined according to the soil acceptance. The anchor pile steering wheel needs to use our steering wheel rotation durability fatigue testing machine before leaving the factory. There should be methods to prevent rotation or floating

4. Construction staff are strictly prohibited from reciting lessons, and shall not affect others' safe work, and have the right to prevent others from reciting lessons

5. Construction staff are strictly prohibited from doing homework after drinking

6. Employees entering the construction work area must wear safety helmets accurately

7. Construction staff must accurately use personal rest protective equipment

8. In case of thunderstorm, rainstorm, dense fog, and strong new year's Eve wind above level 6, do not stop working at heights, hoisting in the open air, tightening lines and other tasks

9. Safety supervisors shall be set up for the stringing construction, and non construction staff shall not enter the construction work area

10. The key accidents to be prevented in the stringing project are: falling in the air, running the line, electric shock (including inductive electricity), object strike, collapse of overtaking frame, drowning, fire alarm and traffic accidents

because the tightening construction is a large-scale mechanized personal operation in the construction of power transmission lines, and the homework points are separated, so Enron, which ensures the tightening construction, must implement the system of each sentry box in the stringing construction process, which is the most fundamental and primary Enron method.
