Sewer pipeline well with safety fall-proof measure and design method thereof

Abstract

Disclosed is a sewer pipeline well with a safety fall-proof measure. The sewer pipeline well comprises a sewer pipeline well body, and the sewer pipeline well body comprises an underground well fall-proof safety cage, a well cover, a well frame and a radius difference platform which is arranged on the underground well fall-proof safety cage; the well cover is arranged on the radius difference platform; the well frame is arranged around the well cover; the underground well fall-proof safety cage is perpendicular to a level road, and comprises an outer wing circle, six vertical supporting rib columns and a bottom safety plate; the outer wing circle is connected with the six vertical supporting rib columns in a welded mode, and the six vertical supporting rib columns are connected with the bottom safety plate in a welded mode; the outer wing circle comprises an outer square column circular ring, six horizontal supporting ribs and an inner square column circular ring; and the six horizontal supporting ribs are welded evenly between the outer square column circular ring and the inner square column circular ring. According to the sewer pipeline well with the safety fall-proof measure, a fixing mode that the radius difference platform is engaged with the outer wing circle is adopted, so that even though the well cover is washed away by water, the fixation of the sewer pipeline well is not affected.

Description

technical field [0001] The invention belongs to the field of urban underground engineering and the field of urban drainage system construction, in particular to [0002] Sewer pipeline well with full fall prevention measures and its design method. Background technique [0003] At present, with the in-depth promotion of sponge cities and the construction of urban transportation in full swing, large and medium-sized cities in my country will surely set off a new round of climax in underground engineering construction. Among them, more and more attention has been paid to whether the city has good "elasticity" in terms of adapting to environmental changes and dealing with natural disasters caused by rain, and urban underground water pipe wells are also one of the important contents of urban underground road engineering research. [0004] "Sewer" is an imported word from Japanese. The word "sewage" indicates that it is used to collect and discharge urban domestic sewage, industr...

AI Technical Summary

Problems solved by technology

[0007] At the same time, there are also major security risks

One is that the ropes are all made of soft materials, with a short service life and cycle, and need to be replaced from time to time, and the time of inspection and replacement is uncertain

The second is that the time between its deformation and destruction is relatively short, and a person's fall may directly lead to the destruction of the device, and it cannot achieve an absolutely safe and reliable effect.

Moreover, in cities with a lot of rain, there is usually a situation where the city is blocked and the rainwater cannot be discharged. The sewer manhole cover and the light weight anti-fall net and manhole cover net are more likely to be swept away by the flood, which brings great harm to the traffic of urban people. serious problem
