like!Jihei high -speed detection engineers are not afraid of "baking" inspection construction

In July, the land of Longjiang, through the blue sky, hanging a fireball -like sun, burning each road construction site. The jurisdiction section of the Jihei High Speed ​​S1 Center Laboratory undertaken by Heilongjiang Provincial Daoqiao Testing Center Co., Ltd. is everywhere. The test and testing engineer follows up the test in time. They compete with Futian high temperature. Wire.

"During this time, the temperature was too high. As soon as I entered the sky, the surface temperature reached nearly 40 degrees Celsius at noon, like steamed sauna." Zhang Genfu, director of the S1 center laboratory, told reporters that in the recent period of time The "summer offensive" was carried out. As the largest highway construction project in the province, the Jihei project was full of energy. With the safety and quality of the province, the construction period was grabbed. The shutdown is constantly in "fighting".

In the B1 bid beam beam, workers are busy and busy, and the row of box beams have been completed in prefabricated. With the cooperation of the testers of the bid section, I saw the test engineer Ye Tiankun picked up the rebound instrument to make the energy on the rebound detection. There are 16 points in the area, 10 testing areas, and whether the box beam (strength) is qualified. Just after the test area was tested, a large grain of sweat flowed out of the helmet, dripping down the dark cheeks. The sweat blurred his eyes, Ye Tiankun picked his arms, wiped with short sleeves, and devoted himself to intense work. "The strength reaches C50 or higher, and the rebound is just a reference. The important thing is to take the standard test block." Ye Tiankun said.

In the heat wave, the test engineer Yu Jiawei knocked on the end of the beam ending anchor with a hammer. With the cooperation of the project tester, the two channel sensors were connected to the fixture in turn. The two channels of CH1 and CH2 are connected to the acceleration sensor of the excitement end, opened the power supply, and established a engineering name. With the full length method, the density of the tract plasma began. The assistant continuously hits the vibration cone and the vibration hammer. He looked up at the anchor side for a while, and then looked down at the wave type data of the instrument host. Each hole was collected 3-5 data. Situation is qualified only by more than 85%. "This kind of instrument is advanced, which can be detected quickly and qualitatively on the denseness of the tutium. It can also be positioned and detected and defined by the type of defects. The detection process is not affected by the ripple material."

In just five minutes, the sweat was immersed in the dark skin, and the shirt was tightly attached to the body, watching a set of data, and Yu Jiawei picked up the mineral water "Guru, Guru" " After drinking a few mouthfuls, I wet my lips, turned around and devoted themselves to busy work.

The high temperature weather that lasted more than thirty degrees for more than 30 degrees, and the entire construction site was baked. The engineers of the S1 center laboratory have undergone the "baking" test of the sun. Although the sweat was soaked in his clothes and the sun was darkened, they still kept in their posts silently.

At the construction site of the A1 section of the A1 section of the China Railway Bridge Bureau, the vehicle shuttled and exchanged, and the bulldozer and the roadside aircraft were facing the hot sun, and the horsepower worked on different operating surfaces. The inspection engineer Zhang Hongyang was led a colleague in the standard substrate with a diameter of 20 cm.

This is a very common sand irrigation method detection pressure. After the test potholes are dug, turn on the sand -filled sand -filled sand -filled sand tube to allow standard sand to flow into the hole. Wait until the sand in the sand tube no longer falls, that is, when the experimental pit is filled with standard sand, put the lower side on the lower side, lower the lower side, and put the lower side. The switch is turned off again, and then weighs the weight of the remaining amount. In this way, the sand weight in the experimental pit can be calculated, and the pits can be calculated based on the density of the sand.

Standing on the ground on the ground with a temperature of more than 40 degrees on the surface, the heat waves rolled up from the feet, and sweat kept pouring out, but they were silent and concentrated. After a while, the test was completed.

"The heat is a bit hot, but now it is the key period of" summer attack ". I have participated in the work for four or five years. In this kind of hot weather, it has been accustomed to it. There are always people who do it, I do n’t do it, and others will do the same. I ca n’t affect the dry and fast up that because of high temperatures ... ”I can feel the responsibility and responsibility of the test personnel. (Jiang Jiuming Reporter Shi Yansong)
