Drain pipe - Cast iron drain pipe - Bridge drain pipe - Bridge PVC circular drain pipe

Description :

　　Our factory processes and produces various specifications of drainage pipes all year round, including cast iron drainage pipes, bridge drainage pipes, bridge PVC circular drainage pipes, and the construction of drainage pipes should be carried out according to the design requirements. PVC drain pipe is a plastic product mainly made of resin, with appropriate additives added, and extruded or injection molded. Sometimes, in order to simplify the construction and save materials, the construction unit of the drainage pipe factory can directly reserve horizontal holes on the safety belts or curbstones on both sides of the roadway, and use iron pipes or PVC pipes to discharge water outside the bridge The pipe mouth should extend 0.02-0.03m from the component to facilitate dripping. Strictly implement the system of full process inspection and supervision by project management personnel, and strengthen the supervision of construction quality. Yesterday, a reporter from Beijing Morning Post learned from the Road Bureau of the Municipal Transportation Commission that the main project of improving the landscape of the Beijing Station and Beijing West Station overpasses, which took more than 5 months, has been completed. When the reporter visited the construction site last night, it was learned that in order to reflect the concept of environmental protection, on the basis of completing the landscape improvement, 80% of the railings of the West Station overpass were used as original railings, and the PVC drainage pipes were maximally utilized as old objects. It is reported that after the landscape improvement of the four overpasses, the overall design of the overpasses will be in line with the surrounding environment, and the comfort level of pedestrian traffic will also be greatly improved. Last night, a reporter from Beijing Morning Post saw at the North Square of Beijing West Railway Station that the main construction of the pedestrian bridge in front of the station had been completed, and the staff were carrying out the final work. According to Ke Huli from the Beijing Urban Road Maintenance Management Center, Beijing Station and Beijing West Station are important transportation hubs in Beijing.

　　Our company's bridge drainage pipes are corrosion-resistant, aesthetically pleasing, easy to install, and cost-effective; From the appearance, it can be divided into two types: circular and rectangular. The length of the circular drainage pipe is 420mm, the length of the pipe is 320mm, and the steel sleeve and grate 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 is about 8kg-18kg, and the price varies depending on the specifications. The price of the circular drainage pipe ranges from 60-80 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 specific size depends on the drawing!

　　Considering the production and transportation cycles of highway drainage pipes, most customers inquire in advance and provide corresponding installation drawings. If the drainage pipe is relatively thin and has too many bends in the design, it will cause poor drainage and aging, resulting in water leakage from the interface. If the bridge drainage pipe extends too short from the guardrail or has an incorrect inclination angle during construction, it is easy to accumulate and block, forming water accumulation and seepage, shortening the service life of the bridge. Therefore, when purchasing bridge drainage pipes, do not blindly listen to price quotes, you get what you pay for. The other end is anchored to the tower. Afterwards, symmetrically construct or install beam segments on both sides of the tower, and then symmetrically install diagonal cables. Afterwards, the inclined cable is tensioned to the research tonnage and anchored to the tower or beam, and the weight of the beam segment is transmitted to the tower through the inclined cable. Because the diagonal cables and beam segments on both sides of the tower are symmetrical, the horizontal components of the diagonal cables on the tower are balanced with each other, and the vertical components are transmitted from the tower to the ground. From now on, cable-stayed bridges with bridge drainage pipes no longer need to balance horizontal forces through strong anchor rotation like suspension bridges. How to define a rectangular cast iron drainage pipe and how to define it as of November 20, 2016. There are two definitions of torque. Next, we will explain them one by one. The definition of rectangular cast iron drainage pipe is commonly used for drainage of railway bridges, guardrail support of highway side bridges, engineering and chemical sewage systems, etc. The construction of rectangular cast iron pipes should be carried out in accordance with the design customization requirements, and the drainage pipes should extend no less than 30 millimeters from the bottom of the structure, relative to overpasses and bridges on highways with a longitudinal spacing of less than or equal to 4 meters.
