Recently, according to the relevant notice requirements of Wuhan Chengtou Group Co., Ltd. on the prevention and response of a new round of low-temperature rain, snow and freezing disasters, Wuhan Holding Company quickly launched the emergency plan, notified its companies to enter the state of "war" as soon as possible, deployed manpower and materials, and took multiple measures to guard the "main position" of safe water supply and drainage in winter, ensure the safety of project construction, do a good job in the anti-freezing and smooth work of the Yangtze River Tunnel, and work together to build a solid line of defense against wind and snow.
Water supply: Bathing in the "snow" to fight to protect people's livelihood.
Operate the internal circulation pump maintenance side station for employees.
In order to do a good job in cooling and anti-freezing and ensuring supply, so that the masses can spend the Spring Festival warmly, the cadres and workers of Baihezui Water Plant under Wuhan Holding Company are united, actively implement various ice and snow anti-freezing countermeasures, and hold many special meetings on "ensuring safety and anti-freezing", putting safety production in the first place to complete the task of ensuring supply, and implement emergency disposal related matters according to the content of the emergency plan in the plant, emergency repair personnel are on duty in a timely manner, strengthen the safety inspection of water supply equipment and facilities, and sort out production materials, emergency repair materials, protective equipment and other reservesto ensure emergency supply and effectively ensure the safe operation of the plant.
On February 2, the freezing rain came as scheduled, Chen Shuangyong and Tian Hu, members of the emergency repair team of Baihezui Water Plant, gave up their lunch break and took the initiative to inspect the plant after finishing the maintenance work in the morning, in addition to inspecting the key equipment and facilities, they also focused on inspecting the standby equipment in various parts of the plant, checking the mud discharge valve of the grit tank, replacing the transfer switch in the control box of the residual water pump, and checking whether the backup pump of the control box of the raw water lifting pump can be opened and operated normally, until it was confirmed that the equipment was in good condition and could be used at any time, and they returned to the office when they were soaked, change into overalls, drink a cup of hot tea and return to work in the afternoon.
Drainage: Carefully maintain the "frozen" authenticity.
"Warm clothing" is worn for firefighting facilities
In view of the characteristics of decreasing raw water temperature and weakening sludge activity in winter, since the beginning of winter, Wuhan Urban Drainage Development Co., Ltd., a subsidiary of Wuhan Holding Company, has paid close attention to changes in water quantity, water quality and water temperature, paid attention to process adjustment and maintenance of insulation facilities, covered and insulated the biological pool, appropriately increased the concentration of activated sludge in process adjustment, and at the same time, carried out preventive process adjustments for the impact of water temperature changes on microorganisms, and made every effort to build a solid water quality safety barrier.
Before the arrival of low temperature, rain and snow, the staff of the drainage company put on "warm clothes" on the pressurized pipes, fire hydrants and other equipment and facilities pipelines, and maintained them in time if they were found to be damaged or missing; Pay close attention to the operation of the equipment, adjust the operation parameters of the equipment in a timely manner, scientifically schedule, and refine the layout to ensure the stability and efficiency of the equipment operation; Through patrol inspection, remote monitoring, infrared temperature measurement and other means, we can comprehensively and three-dimensionally grasp the real-time operation of equipment and facilities to ensure that there are no dead ends and omissions in the cold and freeze prevention work of the equipment.
Construction: to deal with the "freezing" skillfully with dynamic treatment.
In order to ensure the normal operation of production and projects under construction during the cold wave weather and before the Spring Festival, Wuhan Water Construction Engineering Co., Ltd., a subsidiary of Wuhan Holding Company, quickly organized a special deployment meeting for low temperature, rain, snow and freezing weather.
The engineering company carried out a special meeting on safety production.
Recently, the leadership team of the engineering company carried out a special inspection on the construction site for cold and freeze safety production, and carried out key inspections on the construction electricity at the project site, high-altitude operations, cold and warm work of construction personnel, and fire safety work in winter, requiring each project under construction to establish an emergency rescue team, prepare sufficient low-temperature rain and snow anti-freezing materials, and strengthen emergency support preparations for personnel, equipment, materials, and communications; Strictly implement the 24-hour duty system and the project manager with the shift system, strengthen the monitoring and forecasting and early warning of low-temperature rain, snow and freezing weather, and immediately organize personnel to clean up and eliminate potential safety hazards once there is heavy snowfall; Strictly implement the reporting system for emergencies, major situations and emergencies, carry out emergency drills in a timely manner, and effectively build a solid bottom line for safety production at construction sites.
Tunnel: Facing the "cold" and going up to ensure smooth flow.
Compact responsibilities, refine measures, and make every effort to ensure smooth flow. On January 30, Wuhan Yangtze River Tunnel Construction, a subsidiary of Wuhan Holding Company, held a special meeting to analyze the laws and characteristics of low temperature ice and snow, annual festivals and winter safety production in combination with the work of various departments, study and judge various safety risks that may occur, and deploy control measures in a targeted manner.
Starting from January 31, the tunnel company issued low temperature weather warning information in the working group as soon as possible; In view of the risk that the snow and ice on the road at the entrance and exit of the tunnel may be frozen due to low temperature ice and snow weather, resulting in the slippage of passing vehicles out of control, the tunnel company has recently strengthened the monitoring of driving in low temperature weather, the inspection of the road surface of the open section of the tunnel approach road at night, and timely arranged the anti-freezing prevention work and related measures on the road surface at night. Comprehensively inspect the operating conditions of substation and distribution equipment, carefully check the parameters of electrical protection devices, implement safety measures to prevent small animals, and prevent electrical accidents; Strengthen inspections on tunnel structural joints and cable entrances and exits, and deal with problems in a timely manner; Strictly implement the system of leadership and 24-hour duty, and report emergencies as soon as they are found.
It is the responsibility to defend the land, and the responsibility to defend the land. The relevant person in charge of Wuhan Holding Company said that the company will take the sense of responsibility of "always rest assured" and the style of "strict, tight, deep, meticulous and practical", take the prevention and response to low-temperature, rain, snow and freezing disasters as an important task, further improve the work of cold prevention and emergency protection, and fight a "protracted war" against cold with "moving" and "freezing", and stick to the "lifeline" of urban water supply and drainage.
