Description :

　　According to the different forms of bridges, the daily maintenance work of the drainage system includes (1) if the drainage pipes and channels on the bridge deck are blocked, they should be promptly unblocked and kept unobstructed regularly. The lower end of the drainage pipe should be exposed 5-10cm above the bottom of the upper structure. (2) When the waterproof layer of the beam bridge is damaged, it should be repaired in a timely manner. The waterproof layer should be made of materials with good waterproof performance; When laying the waterproof layer, it should be carried out at a temperature not lower than+5 ℃. (3) The bridge deck should maintain a transverse slope of 1.5% to 3.0% to facilitate bridge drainage. (4) When the longitudinal slope gradient of the bridgehead junction is greater than 3%,In order to prevent a large amount of rainwater from leaking into the bridge deck from the bridgehead, it is advisable to set up intercepting ditches at the bridgehead (5). For closed drainage systems installed on urban bridges and overpasses, regular inspections should be conducted to ensure that all drainage pipes are unobstructed, cracked or damaged; Whether the facilities of the system, such as the pumping pump, are working properly, and if there is any blockage, they should be cleared in a timely manner. If there is any damage, they should be replaced in a timely manner.The total length of the circular drainage pipe is 420mm, with a straight pipe length of 320mm. The steel sleeve and grille cover are 10mm in total. The outer diameter of the horn mouth is 215mm, the inner diameter is 161mm, and the inner diameter of the circular drainage pipe at the bottom is 100mm. The individual weight ranges from 8kg to 18kg, with different specifications and prices. The price of the circular bridge cast iron drainage pipe varies between 70-150 yuan; The commonly used rectangular drain pipe is 600mm, with an outer diameter of 170mm and an inner diameter of 140mm. The inner diameter of the bottom outlet is 100mm; the price of rectangular bridge cast iron drain pipe is mostly around 100-300 yuan! The construction of circular drainage pipes should be carried out according to the design requirements. The drainage pipes should protrude from the bottom of the structure by no less than 30mm and have a longitudinal spacing of no more than 4m.The construction of circular drainage pipes should be carried out according to the design requirements. The drainage pipes should protrude from the bottom of the structure by no less than 30mm and have a longitudinal spacing of no more than 4m. For bridges on overpasses and highways, the drainage pipes should not be hung directly under the slab. They can be directly led to the ground through longitudinal and vertical drainage pipes. The circular drainage pipe adopts a flat mouth connection, which requires high quality of the pipe material. It also has high requirements for the outer diameter ovality, wall thickness, and physical properties of the rubber ring of the drainage cast iron pipe. Due to the poor water tightness of the flat mouth, in addition to strictly controlling the body quality of the pipe material and fittings, special attention should be paid to the protection of the pipe material and fittings to ensure the ovality and flatness of the ports. Circular drainage pipes have developed with the development of the national economy. Commonly used specifications can be shipped on the same day to ensure quality, and come with a test report and certificate of conformity when leaving the factory. Large factories, with quality assurance, must customize according to the drawings. Generally, it takes less than seven days to make molds for circular drainage pipes and ship them, while rectangular pipes take slightly longer due to their complexity compared to circular pipes. It takes 15 days from mold making to shipment. During the production pouring of the bridge drainage pipe in our factory, induction furnace melting is often used to effectively control the temperature of the molten iron; Because excessive pouring temperature can cause the sand mold to expand, and when the pouring temperature is ≥ 1420 ℃, the amount of waste will increase; When the pouring temperature is 1460 ℃, the waste reaches 50%. Therefore, customers can rest assured to purchase our cast iron drain pipe, which meets the wall thickness standard, has excellent quality, and can be delivered quickly.
