Drilling beam "steamed sauna" topped the "scar" high -speed maintenanceman to seize the golden period of summer construction

Since the beginning of the summer, it has suffered from high temperature "baking inspections" throughout the country. All parts of the province practice the people -centered development ideas, explore various cooling tricks, and give workers under the scorching sun to have a more comfortable working environment. However, such a group of people must adhere to their posts at high temperatures due to their own characteristics. Although sweating like rain, they never slack. In the past few days, the reporter has entered these "heat" positions that cannot be separated from people and witnessed the hottest moment.

In summer, because of the good repair effect, the construction of the construction of highway maintenance and maintenance, the builders could not hide or go.

On August 1st, Wuhan's around the city highway, Suiyue high -speed Tianmen section of the heat wave rolled, and the reporter visited the bridge maintenance and highway maintenance builders who were sweating.

"Steamed sauna" in the box beam

The clothes can be screwed out of sweat

At 11 o'clock, by the Hanjiang River in Caidian District, Wuhan City, under the bridge of the Hanjiang Highway Bridge of the Western Section of Wuhan West Section of Wuhan, a scaffold was carried on the bridge pier. The reporter climbed the 80 -level spiral red ladder, climbed to the beam under the box under the bridge at a height of 25 meters.

The large -scale bridge maintenance and reinforcement project has been underway here for 21 years. "Early the hidden danger is related to driving safety. It is planned to be completed at the end of August, so it is necessary to" white+black "to grab the working period." Said Ren Wei, a maintenance safety inspector of the Second Comprehensive Inspection Office of Jingzhu Operation Company in Hubei.

Climb up the narrow vertical iron ladder, bend over into the bridge box, a heat wave comes with dust. The box beam is a closed space of about 120 meters long and high height. More than 30 builders are "diseased" repairing, pasted steel plates, and cut materials.

"Summer is the most difficult. It is a few hours in a few hours. There are 3 short -sleeved shirts in the box. The shirt in his safe vest was wet, and he could twist sweat, and the sweat made him look blurred.

The closed box is like a "sauna house". Despite the air offer, the breathing is still tight and hot. The actual temperature of the reporter reached 48 ° C. The maintenance and reinforcement of only 800 meters in the box beam was more than 800 meters. Ren Wei took the seams to search for the "disease": "A hair is not let go." There was also the work team drilling the construction and comprehensive inspection. Ren Wei, 41, said that in one day, it is common to take 20,000 to 30,000 steps. It is common to eliminate more than 300 bridges "diseases" in a few months.

The reporter saw that high -tech means of box beam repair and reinforcement, such as the use of advanced detectors to accurately detect the distribution of reinforced bars, can "see" underground reinforced distribution, so that the original reinforcement is not hurt during drilling. High -altitude transportation materials also use the "mountain climbing tiger" (small rail transport vehicle) to reduce the strength of manual handling at high temperature. Even so, steel plywood reinforcement, "disease" repair, etc. need manual operation.

The closed box signal is weak. In order to prevent the transmission of information such as heat stroke such as heat stroke, Jingzhu operating company is equipped with a walkie -talkie in the construction personnel. Essence

Pittering can not be handled at night

Pour in the heat wave 165 ° C concrete

At 13:30, standing on the Tianmen section of the Suiyue Expressway, the scorching sun was the first.

"Report, the pits are found in front, and you need to deal with it immediately!" After receiving a report from the hiking inspector, Hubei Investment Sui Yue operating company's second comprehensive inspection office supporter Chen Cheng and the supervisory team leader Deng Nianrong and others quickly arrived at the scene.

The highway "three -point construction, seven -point maintenance", highway maintenance is the top priority. Pittering is one of the most common "diseases" on high -speed high -speed. If it is not dealt with in time, cars driving at high speeds are prone to bumps and even explosive tires to cause accidents. Therefore, Suiyue's operating company requires that "the pits can not be repaired overnight."

The pits in front of the eyes are located on the highway traffic lane, with a diameter of about 1 meter. Deng Nianrong said that if it is not repaired in time, it will produce greater "diseases" under the scouring of rainwater.

The cutting machine rang, and the workers first cut into a rectangular shape around the pits, about 20 cm in depth, and then crushed the concrete around the pits groove with an electric pick. After the pieces were cleared, a square groove was formed on the road. "The seam must be straight, the paving should be uniform and full, and the pits are a fine work." Deng Nianrong, 59, said that no matter what time, he had to be in place immediately.

The reporter was measured by the thermometer, and it had exceeded 50 ° C. After the comprehensive maintenance truck, known as the "king of the road", he heated the temperature a little again. It can heat the asphalt concrete to 165 ° C by its own mixing system. I saw the black asphalt concrete rolling down, and poured into the pits "creating". Finally, the construction personnel unloaded the rolling machine hanging at the front end of the vehicle and pushed the roads of the new shop repeatedly.

One hour later, the pits were successfully repaired. The sweat had wet the 28 -year -old Chen Cheng shirt and reflective vest, and the sweat beads dripped on the road along his cheeks. He took a sip and drank two bottles of mineral water.

In the middle of the Suiyue Expressway for 15 years, 13,000 vehicles were passed, of which more than 60 % were trucks. The traffic volume was higher than the average value of the province.

Chen Cheng introduced that it was the fastest day to deal with such pits in the past. Now there are advanced equipment and new materials such as "king of roads" and new fast concrete. The work intensity is much smaller.
