Description
Technical field
The invention belongs to drainpipe technical fields, and in particular to a kind of reinforced concrete sewer pipe.
Background technique
With the development of urban construction, start to build sewage treatment plant, a large amount of industrial wastewater and sanitary sewage need logical
It crosses drainpipe and enters sewage treatment plant, and often containing acid or other corrosive substances in black water, this requires drainings
Pipe has stronger corrosion resistance, while drainpipe need to carry certain weight, this just need drainpipe mechanical property and
Toughness and intensity are stronger.
But existing drainpipe is generally existing following insufficient: drainpipe intensity is inadequate, and easy fracture, corrosion resistance is poor,
To influence the service life of drainpipe.
Summary of the invention
For above-mentioned deficiency in the prior art, the present invention provides a kind of reinforced concrete sewer pipes, can solve existing
Drainpipe intensity it is inadequate, easy fracture, corrosion resistance is poor, thus the problem of influencing the service life of drainpipe.
To achieve the above object, the technical solution adopted by the present invention to solve the technical problems is:
A kind of reinforced concrete sewer pipe includes: the first fixing layer, pervious bed and the second fixing layer from outside to inside；Wherein,
The thickness ratio of first fixing layer, pervious bed and the second fixing layer is 1-2:1-2:4-6；
