Description :

　　Bengbu Drainage Pipe - Circular Cast Iron Drainage Pipe for Expressway Drainage Pipe Supply Bridge Drainage Pipe Due to its unique cast iron process, it is not easy to rust, maintenance free, and not easily deformed at high and low temperatures, with a long service life; It has been commonly used in various bridges; According to different materials, it can be divided into two types: cast iron drain pipes and PVC drain pipes; PVC drainage pipes have low strength and are prone to deformation Very poor weather resistance Short service life High maintenance costs; Gradually replaced by cast iron drain pipes; Bridge drainage pipes can be divided into two types based on their external dimensions: circular drainage pipes and rectangular drainage pipes; The commonly used ones are a total height of 420mm, a large mouth inner diameter of 215mm, a small mouth inner diameter of 100mm, and wall thicknesses of 5.5mm.7mm.8mm.10mm The common specifications for rectangles include 125 × 400mm, 160 × 447mm, 125 × 300mm, 125 × 510mm, 125 × 600mm, 160 × 585mm, etc. Generally, circular shapes can be ordered and shipped on the same day!

　　Bridges on overpasses and highways should not be directly hung under the slab. Drainage pipes can be directly led to the ground through longitudinal and vertical drainage pipes, or according to planning requirements. The pipes should have protruding fixed equipment such as anchor rails, clamps, and other embedded parts.

The bridge cast iron drainage pipe is suitable for paving structures with layers. Widely used in municipal, transportation, construction and other fields, especially in railways, highways, airports, roads, drainage facilities on both sides of bridges, cast iron drainage pipe manufacturers' construction should be carried out in accordance with planning requirements. The cast iron drainage pipe of the bridge extends no less than 30 millimeters from the bottom of the structure, with a longitudinal distance of no more than 4 meters.

　　The construction equipment process is achieved through the following process: the reserved hole mold equipment for the drainage pipe is installed on the prefabricated beam combination fixed template. Mix the measured water and grouting material evenly in the mixing ash drum, with a water cement ratio of 0.18-0.1822; Pour the manufactured grouting material into the cavity formed by the drainage pipe and the reserved hole of the drainage pipe, with the grouting material lower than the upper opening of the drainage pipe, and apply polysulfide sealant for construction. The strength of the grouting material to be poured is greater than 22Mpa. Rectangular drainage pipes are commonly used bridge cast iron drainage pipes. Rectangular bridge cast iron drainage pipes are mainly used in railway drainage, guardrail supports on both sides of highways, engineering, and chemical sewage systems. The construction of rectangular bridge cast iron drainage pipes should be carried out according to the planning requirements. The bridge cast iron drainage pipes should protrude from the bottom of the structure by no less than 30mm and have a longitudinal distance of no more than 4m. b. For overpasses and highways. The cast iron drainage pipe for bridges should not be directly hung under the slab.
