The invention provides a safety fence for an urban sewer opening. At present no safety protection facility is provided for the urban sewer opening in China; in some places, no well lid exists (stolen or damaged), casualty accidents caused by pedestrians fall into the sewer happen occasionally, and great potential safety hazards are formed. As a result, mounting the protection facility is imperative. Recently, protective nets and iron grids are mounted on the sewer openings in some places to achieve the protection effect; however, due to material problem and unscientific design, the protection facilities will be damaged in 3-5 years to cause potential safety hazards. The safety fence for the urban sewer opening is developed by use of the characteristics of a PVC water feed pipe, a PPR cold/hot water pipe and a steel pipe. The safety fence is manufactured from proper materials, and is simple and scientific to manufacture, low in cost, high in weight bearing capacity, good in protection performance and good in anti-theft property. Besides, the safety fence is durable and has the service life of 50 years; once the safety fence is mounted, the safety fence does not need to be maintained once for all; as a result, the problem of safety protection of the sewer is fundamentally solved. The safety fence can be mounted on newly built or modified sewers very conveniently, and is suitable for popularization and application in cities in China.
