Guizhou Zhijin drain pipe, cast iron bridge drain pipe

Product introduction:
Cast steel drain pipe is made of iron and steel as the base material and is produced by molding process. Its superior features include high mechanical strength, strong corrosion resistance and long service life. It is widely used in municipal administration, transportation, bridges, construction and other fields. It is an ideal replacement product for cast iron drain pipes, steel drain pipes and ceramic drain pipes.
Performance characteristics:
, high mechanical strength, bending strength -, impact toughness 3-/㎡, bending and compression resistance.
, light weight and density of ./, easy to transport and install.
Strong corrosion resistance, resistant to erosion by chemical solvents such as acids, alkalis, and salts.
, Long service life, up to more than 10 years.
Application scope:
Water drainage in municipal administration, transportation, bridges, buildings, etc.
The construction and installation process of bridge drain pipes solves the technical problems of traditional pre-buried drain pipes. Instead, the process of pre-buried drain pipes, reserved hole molds, and then installing the drain pipes is achieved through the following steps:
Fix and install the drain pipe with reserved hole mold, pour concrete, cure, remove the formwork, and remove the reserved hole mold
Prepare the drain pipe, wrap a circle of water-expandable rubber water-stop strip around the drain pipe, and apply it on the exposed part Anti-corrosion coating
Preparation and pouring of grouting materials for installing and fixing drain pipes
The advantage of applying polysulfide building sealant is that it is easy to assemble and disassemble the formwork, install and fix the drain pipe easily, and shorten the pouring cycle of prefabricated beams and The total construction period ensures smooth drainage on the bridge deck. This technology is widely used in the construction and installation of drainage pipes for bridge deck drainage
