Typhoon "Parrot" is approaching. Is the city's underground pipeline network ready to face it?

Typhoon "Parrot" is about to make landfall. Every year, typhoon precipitation is an important water source for our country's summer and autumn seasons. All provinces and cities in our country, except Xinjiang, can be affected by typhoons and experience significant rainfall. About 80% of typhoons produce heavy rainfall exceeding 50mm after making landfall, with more than 30% of daily rainfall reaching over 200mm (extreme heavy rain). According to precipitation records analyzed before 1977, 6 out of 7 super extreme heavy rain events with daily rainfall of 1000mm in our country were related to typhoon impacts.

However, the short duration and strong rainfall not only bring abundant water resources to the inland but also impose strict requirements on the urban underground pipeline network.

Cities experience waterlogging due to rainfall, entering a "sea view" mode, which has repeatedly become a hot topic online. Currently, waterlogging in some urban areas is often due to issues with the drainage system, such as "old age, small capacity, and few outlets." Some urban pipelines have long exceeded their service life, and there are also unreasonable aspects in the layout of the underground drainage pipeline network. When rainfall is concentrated, a large amount of silt and garbage is washed into the underground drainage network, preventing it from effectively performing its drainage function.

It is very necessary to plan ahead and做好防汛工作, to prevent disasters and reduce risks. To this end, Zhongtong Environmental Sanitation has developed an efficient and intelligent product specifically for municipal pipeline maintenance - the underground pipeline clearing vehicle.

Underground pipeline clearing vehicle

It is suitable for urban sewers, urban drainage, emergency rescue, sanitation, industrial drainage pipelines, water services, and other industries for pipeline clearing and cleaning operations.

Based on the actual situation of domestic sewers, a clearing nozzle that can float on the surface of the sewer liquid has been developed. Combined with hydraulic scraping of garbage, it can quickly and thoroughly clean the garbage in the sewer, a first in the country.

It can clear siphon sewers with well depths of over 10 meters, sewer diameters of 2 meters, and distances between two wells of over 80 meters. During the clearing operation, a 60-meter long underground pipeline can be cleared and cleaned within 5 minutes.
