Customizable Bridge Steel Ductile Iron Rectangular Rain Gutter Drain Pipes

Circular bridge drainage pipes commonly used have a total height of 420mm, with a large diameter of 215mm and a small diameter of 100mm. The wall thickness options include 5.5mm, 7mm, 8mm, and 10mm. Sizes such as 125×400mm, 160×447mm, 125×300mm, 125×510mm, 125×600mm, and 160×585mm are available.

Bridge Cast Iron Round Drain Pipe

The construction and installation technology of bridge drainage pipes, involving the construction and installation technology of bridge drainage pipes, addresses the technical issues of traditional pre-buried drainage pipes by replacing them with pre-buried drainage pipe预留孔洞molds, followed by the installation process of the drainage pipes, which is achieved through the following steps:

(1) Fixed installation drain pipe hole mold预留

(2) Casting concrete, curing, removing formwork, and dismantling pre-drilled hole molds.

(3) Prepare the drain pipe, wrap a rubber water-swelling sealing strip around the drain pipe, and apply anti-corrosion paint to the exposed portion.

(4) Install fixed drain pipes.

(5) Mixing and Pouring Grout Materials

(6) The polythiols building sealant offers advantages such as easy assembly and disassembly of formwork, simple installation of fixed drainage pipes, shortened precast beam casting cycle, and overall construction period. It ensures smooth bridge surface drainage, and this technology is applied in the construction and installation of drainage pipes for bridge decks.
