Yantai workers wear gas masks to clean the river

Recently, at the mouth of the Tiger Rock at the eastern side of Shengli South Road in Zhifu District, workers at the drainage department of the Yancheng Urban Management Bureau wore gas masks to enter underground rivers that were nearly two meters high. A black car was cleared from the river.

As the main flood discharge channel in the urban area, the river channel bears the security issues throughout the flood season. In 2014, the Drainage Department of Shanghai Urban Management Bureau planned to collect more serious steel pipe rivers, Tongshen River, Happiness 5 rivers, Xiaoqu River, Daeyang River (south section of West Avenue), Shaoshan River, Tiger Rock River and interception The dredging maintenance will be carried out. It is planned to excavate approximately 17,500 cubic meters of silt and maintain approximately 80 cubic meters of river bottom. When the project is completed, it will greatly increase the flood discharge capacity of the river.

Dredging rivers should wear gas mask rotation work

At 9 o'clock in the morning, when the reporter came to the mouth of the Tiger Rock River, he smelled a pungent smell of mud. Two blowers blew on the dark river. The water workers in the river wore water shoes and gas masks and transported the black silt of a car to the mouth of the river.

The rivers in the urban areas are mostly dark rivers, and many have been in service for half a century. The conditions in the river channels are complex and the operating risk factors are high. "Two hours before construction, uninterrupted forced ventilation is performed using a blower. Operators carry gas detectors into the river to carry out toxic and hazardous gas detection. After testing, they can enter river operations." Personnel entering the river must wear gas masks and rotate their jobs. One of the operators in the river channel must wear a walkie-talkie and a gas detector. After the toxic gas exceeds the concentration, the detector will automatically alarm. “It has been a good thing for several years. This is a familiar experience.” Worker Lao Song laughed and said that the dredging of river crossings is relatively simple. Entering the river channel requires access from the inspection well. The highest place is about 1.7 meters. The lowest point is less than For 1 meter, workers need to bend over and clean up, and sweat will go down the drain for a while. The reporter saw the side of the job site is also equipped with oxygen tanks, stretchers, rescue ropes and other emergency rescue equipment and equipment.
