There are such a group of people who have long been working in poor underground conditions and it is their duty to ensure the smooth flow of underground water pipes for thousands of households. Their safety work also needs protection. In some places, the Municipal Facilities Administration Bureau has added new technology facilities to ensure the safe operation of dredging workers.

Detector to monitor downhole gas

Above the People's Road underneath the tunnel, a box appeared recently that read: Sewer flammable and explosive gas monitoring system.

“In the past, the sewers didn’t work. Judging by experience, we often needed to go to the sewers to look at them. The taste was suffocating. Now that we have this equipment, we have fewer sniffs in the sewers.” Dr. Lei Xinggui, a dredgeman, said. The reason why this equipment is installed on the road is because it can not stand the harsh environment of the sewer, and it will affect the service life when installed in the sewer.

With this detector, only the gas to be monitored is introduced into the equipment from the sewer pipe. The instrument can quickly monitor the gas changes. If there is any abnormality, the exhaust pump will be started immediately, reducing the concentration of flammable and explosive gases. If it does not, the monitoring center of the Municipal Municipal Facilities Administration Bureau will immediately notify the dredging workers to go to the site to eliminate hidden dangers. With such equipment, dredging workers can pull themselves out of the complexities of routine inspections and concentrate on dealing with key hidden dangers. And before the dredging workers can remove the hidden dangers, they can be aware of the concentration of downhole gas.

High pressure dredging car goes into battle

If the sewer is clogged, it was mainly due to manual cleaning. The dredging workers need to go cats in the sewers and use a shovel to dredge the blocked sewers. This is a large workload and the environment is extremely poor. In the event of a blockage caused by grease in the hot pot, the steel braze cannot be penetrated. .

Now, in this situation, dredging workers do not necessarily need to go inside the sewers. This year, the municipal municipal facilities administration purchased a high-pressure dredging vehicle that can spray high-pressure water. Once the location of the blockage is determined, the dredging staff must do is put the water pipe with a bit on the car into the sewer. , Start the high pressure pump, the drill bit drilled into the plug under a strong pressure, coupled with the impact of water, what plugs can easily collapse. It took a few hours of work in the past and it can be completed in minutes.

In addition to high-pressure drills, this dredging vehicle also comes with a hammer, vacuum suction, and a variety of weapons in one.

Purchased 5 sets of pipeline periscopes

In the past when it was time to go downhole, experienced dredging unions first smelled at the wellhead, and then slowly went down with their feelings. This year, the municipal municipal facilities administration newly purchased 5 sets of pipeline periscopes and 4 sets of long-pipe respirator. With these facilities, dredging workers can still breathe fresh air after entering a well, instead of assaulting the bad air inside the well.

Although the purchase of new types of equipment such as long tube respirator facilitates the work of dredging workers, the harsh working environment is still testing them. If we can start with small things, we will stop the harmful wastes from flowing into the sewers. Avoid danger. Consciously constraining one's daily behavior is a promotion of environmental protection. At the same time, it is also respect for the work of others.
