Use of products produced by pe prestressed plastic corrugated pipe equipment in bridge constructionUse of products produced by pe prestressed plastic corrugated pipe equipment in bridge construction
Let’s analyze the use of the products produced by the prestressed plastic corrugated pipe equipment in the construction of bridges, as well as the product characteristics and application scope:
1. After the metal bellows are processed, the coating will fall off. Improper storage methods or excessive storage time will easily lead to corrosion. After corrosion, holes will appear, which will easily cause leakage and blockage in the subsequent construction.
2. Because the wall of the metal corrugated pipe is thin, it is easy to burn. During the construction process, the welding slag is dropped due to the steel connection and falls onto the corrugated pipe, so it is easy to scald the corrugated pipe.
3. Because the toughness of the metal bellows is not very good, the leakage section reserved at the end of the beam body is easy to break, and the end of the beam cannot be tightly connected when it affects the continuity of the beam.
4. It is easy to hang to the wall of the metal corrugated pipe when threading the bundle, causing the corrugated pipe to accumulate, resulting in poor bundle threading.
5. The leakage of the corrugated pipe has a great impact on the follow-up work, and there are hidden dangers in the construction quality, such as notching the beam due to poor beaming, and poor grouting causing insufficient pressure in some sections.
Now we use plastic spiral molding instead of metal bellows to avoid the above problems.
Prestressed plastic corrugated pipe equipment
Advantages of prestressed plastic corrugated pipe:
1. A special square tube is wound into a spring-like structure, and is melted and connected to a tube by a high-temperature welding rod of the same material at a high temperature. The tube has the characteristics of flexible, compressible, stretchable and flattened spring.
2. Anti-chemical corrosion: not corroded by acid, alkali, salt, no bacteria, algae, no iron, no scaling.
3. Strong impact resistance: it still has good impact performance below freezing point and will not be broken by freezing water.
4. Light weight: The density of polyethylene is less than 1, and it is lighter than water. It is convenient for loading, unloading, transportation and installation, and does not require large-scale hoisting and transportation equipment.
5. The water resistance coefficient is low, which can increase the flow and velocity compared with the diameter pipe.
6. Good wear resistance: the wear resistance is far better than that of metal pipes.
Product features of prestressed plastic corrugated pipe equipment:
1. The pre-stressed plastic corrugated pipe has high compressive strength, strong resistance, strong airtightness, and no leakage or running slurry;
2. The pre-stressed plastic bellows ring has strong rigidity, low friction resistance, anti-aging, anti-electricity and corrosion resistance, which improves the effect of the anti-corrosion and waterproof layer of the pre-stressed steel;
3. The prestressed plastic corrugated pipe has strong endurance and durability, good dielectric strength, good flexibility, and is not easy to be chipped.
4. The prestressed plastic corrugated pipe is easy to install and operate, and the engineering construction is convenient.
The prestressed plastic corrugated pipe is reliable in connection, has good ultra-low temperature impact resistance, good hard crack resistance, solvent corrosion resistance, anti-aging, long service life, good wear resistance, and good flexibility. It is the choice of bridge construction pipes!
