　　The intensity of rainfall and the catchment area are the main factors determining the distance between the drainage outlets on the bridge deck. Secondly, it can also be determined based on the longitudinal and transverse slopes of the bridge deck, as well as the drainage capacity of the drainage pipes, and the allowable width of the overflow section. If the spacing between the discharge outlets is too large or the quantity is not enough, it will cause water on the bridge surface. Especially in the southern regions with abundant rainfall, the intensity of instant rainfall is also high, which can easily cause water accumulation on bridges due to the lack of time to discharge into drainage pipes.

　　The common materials for drainage pipes in Shuntian, Cangzhou include cast iron pipes, PVC pipes, etc. The common cross-sectional forms of drainage pipes include circular, square, etc. Bridge drainage pipes, due to their unique cast iron technology, are 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!
