Xinyang Drainage Pipe - Bridge Drainage Pipe Usage - Customized Cast Iron Drainage Pipe

Description :

　　Yang Drain Pipe - Bridge Drain Pipe Usage - Customized Cast Iron Drain Pipe Our factory produces bridge drain pipes strictly according to the drawing standards, with strict procedures and unique craftsmanship. The surface of cast iron drain pipes and fittings should not have cracks or heavy skin. The commonly used specifications include a circular 420 model priced at 70 yuan and a 600 model priced at 85 yuan, and a rectangular 600 model priced at 180 yuan and a 750 model priced at 200 yuan. 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. Authoritative large factory, quality assurance, those with drawings must be customized according to the drawings. Generally, it takes at least seven days to make molds for circular drainage pipes and ship them. Rectangular pipes are slightly more complex than circular pipes, so the time is longer. It takes 15 days from making molds to shipping. The weight of a drainage pipe depends on its diameter and length. Generally, a drainage pipe with an inner diameter of 10cm and a wall thickness of 2mm weighs 5kg per linear meter. There are many specifications for circular drainage pipes, including 420mm, 215mm, 114mm, and 6-7mm. Taking this as an example, we will explain that this represents a circular cast iron drain pipe with a height of 420mm, a large horn mouth diameter of 215mm, a bottom circular mouth diameter of 114mm, and a wall thickness of 7mm; Corresponding drawings are required for rectangles, which will not be listed here one by one. Horizontal drainage is generally installed with rectangular cast iron drainage pipes at the intersection of wall guardrails and bridge decks. For small bridges with small spans and no sidewalks, sometimes in order to simplify the structure and save materials, horizontal holes can be directly reserved on the safety belts or curbstones on both sides of the roadway, and water can be discharged outside the bridge using iron pipes or PVC pipes. The pipe mouth should extend 0.02-0.03m from the component to facilitate dripping. Cast iron drain pipes can be divided into two types based on their appearance: circular drain pipes and rectangular drain pipes; Therefore, the installation of bridge drainage pipes should be carried out according to the 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 is tilted at the wrong 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 the price quotation, you get what you pay for.What are the precautions for PVC drainage pipe construction? 1、 The selection and storage of pipes should first avoid affecting the construction quality due to material quality issues. Given the uneven quality of the PVC material market, before construction, in addition to checking the manufacturer's certificate of conformity and product manual, necessary self testing of PVC-U pipes should also be carried out, such as observing for bubbles, whether the pipe diameter is regular, whether the thickness is uniform, whether the pipe wall has yellowing or other discoloration phenomena (which may be due to decomposition or aging during the production process), and sampling for bending or vigorous tapping to check for toughness. The shape of the pipe fittings should be regular, smooth, and free of burrs. When storing, attention should also be paid to moving gently, not littering or rolling on the ground. Do not stack outdoors, maintain ventilation, avoid sunlight exposure (strong sunlight on Maodao Island can easily cause the pipes to become brittle and aged), and avoid squeezing. 2、 During the construction of building structures in coordination with civil engineering, it is easy to encounter situations where there are no reserved holes or embedded parts, or the reserved holes are too small and the embedded parts are not marked. As a result, during the hydraulic construction process, the building structure has to be chiseled or even the steel bars have to be cut, which affects the safety of the building. So construction technicians also need to understand the civil construction drawings, and based on the civil construction drawings, determine the reserved size and position of the through wall (floor) slab holes, as well as the number and position of pre embedded parts. When laying drainage pipes in a concealed manner before pouring concrete, attention should be paid to the slope of the pipes, tied and fixed firmly, and personnel should be left on site to guard during pouring to prevent pipe displacement. Civil construction personnel should be reminded to avoid the pipes when inserting, and any damage should be repaired in a timely manner. In the cross construction of civil engineering, pipeline blockage problems often occur, especially during floor leveling operations, where mortar and other debris often fall into the pipes and accumulate at bends or water storage bends, causing siltation. Therefore, the pipe openings extending from the roof and floor should be promptly sealed, and a water test should be conducted before use to avoid rework or affecting use.
