Hot sun burns high table steel workers.

Date of release:2018-07-18 Author: Click:

Above the Yangtze River, more than 30 meters high, the top temperature of the pylon is 51.8 degrees Celsius, the surface temperature of the human body is 40 degrees Celsius, in such an environment, standing for a minute is a sweat. Yesterday morning, the reporter came to the construction site of the Fifth Bridge of the Yangtze River, and the workers of the concrete team of the cable tower felt the scorching sun.

This year is the year of the pylon construction of the Fifth Yangtze River Bridge. The South tower, the North Tower and the middle tower of the main bridge are all under construction. Yesterday, reporters took a boat to the middle tower construction site in the Yangtze River. "The middle tower is 175 meters high, made of 37 sections of steel boxes piled up one layer after another, now completes seven sections, is the fastest progress of the three towers." "The construction of the pylon is a delicate job, and the accuracy requirement is controlled within one-third of the total," said Lai Youman, the project leader of the Yangtze River Fifth Bridge in the Municipal Public Construction Center. What is the 1/3000 concept? Take the central cable tower for example, the tower height is 175 meters after completion, then the errors of left and right deviation should be controlled within 5.8 cm.

On the pylon operation platform, the reporters looked around and did not see the workers. "At this point, the workers are building on the tower." The two China Navigation Bureau of the Yangtze River five bridge project is responsible for the race of AI Xiu, pointing to the height of 30 meters. Next to the pylon was a temporary steel ladder cage. The reporter climbed up 160 steps with Ai Xiu. At last, he reached the top of the pylon. The interview had not begun yet. His clothes were now soaked through.

At the top of the tower, six or seven workers in the concrete team are cleaning up the slurry at the top of the tower. "After each segment is joined together, concrete is required. There will be 10 cm of loose slurry above the 5 m concrete. Only by removing the slurry can the two steel boxes be tightened up." Ai Xiu said that all the floating slurry needs workers to chisel out the buckets and pack them away, which can only be done manually.

There are many steel bars in the construction site. In order to avoid scratching, workers wear long sleeved trousers. Xue Fengyang, a 50-year-old with dark skin and a pair of solid gloves, squatted on the ground crushed stones into small buckets one by one, and then poured them into a side of the special steel box. How many barrels he had to load and how many times he had to run back and forth in a day, the reporter asked Ai Xiu to calculate an account: a layer of concrete floating slurry has 2 tons, a small barrel of 10 jin each time, the need to pour 400 barrels.

In the early morning, the temperature on the top of the tower was getting higher and higher. The steel workers who stood on the steel plate soon began to iron their soles. They measured more than 50 degrees Celsius with a thermometer. Xue Fengyang stopped and sat on the steel plate to finish his homework in the morning. His clothes were soaked with sweat now. He picked up the huge kettle and began to drink it up. "Every time you climb up, you bring a big pot. This pot has 4 jin, sooner or later each pot." Xue Fengyang said.

Don't look at the workers going off duty at 10, but they have been working for more than 4 hours. In view of the high temperature climate, the site has been adjusted to work from 6:00 to 10:00 a.m. and from 4:00 p.m. to 8:00 p.m. every day to avoid the high temperature climate as far as possible. There are still a lot of harder jobs that can only be built at night.

There are 700 straight threaded sleeves firmly connecting the two sections. Reinforcement workers need to drill into the steel sleeve box 5 meters deep and fix one straight threaded sleeve at the joint of the steel shell. The operation space of the steel box is narrow, and the three sides are closed, so long as the upper part is open. After exposure to 60 degrees Celsius in the steel box, workers as if in the "oven" in the work, so the construction side of the reinforcement work on the night, and equipped with blower.

The reporters went down to the floor with the workers off duty and went into the container heatroom. The project department has prepared various kinds of sunstroke products such as cool oil and watermelon for workers. Air conditioners were also installed in dormitories.

It is understood that in addition to the tower, the other five section of the bridge construction is also sticking to rules. Construction of the operation well is under way in Jiangxinzhou tunnel, and the cutter head assembly of the shield machine is being welded. The shield project is estimated to begin in October.
