Trench Excavation Standards for PVC-O Water Supply Pipes and Optimal Backfill Soil Quality
1. Trench excavation must adhere to the highest industry standards, ensuring a robust and reliable infrastructure for successful implementation.
To prevent pipelines from being laid within permafrost layers, it is crucial to determine the trench excavation depth by meticulously analyzing and summarizing local geological data. This ensures efficient backfill operations, which are essential for preventing pipeline and interface cracking due to bending stress. Here are the key requirements:
(1) Trenches must be perfectly straight, with a bottom width not less than the pipe's outer diameter plus 0.5m, ensuring a total width of no less than 0.7m for optimal stability and durability.
(2) Rigorously maintain precise bottom depth, avoiding excess or deficiency. If excessive gravel is present, backfill and compact to specified levels. In areas with hard soil or obstacles, such as stones, trenches may curve slightly for construction ease. Ensure curves remain gentle and depth consistent to avoid pipe bending, preventing undue stress on the pipe, fittings, and joints. Increased water supply pressure can result in joint leakage or rupture.
2. Avoid permafrost-related foundation issues and potential trench settlement. During winter, ensure that pipe trenches are placed on undisturbed soil or well-compacted backfilled ground. High soil moisture content can lead to future permafrost melt and trench settlement, causing pipe sinking, bending, and joint breakage with increased stress. Minor issues may cause joint separation and leaks, while severe cases lead to rupture.
3. Winter pipeline bonding must strictly follow established regulations to ensure system integrity and performance under cold conditions.
PVC-O tube adhesive, primarily composed of PVC-O solvent, functions by applying adhesive to the socket's inner and outer surfaces, causing expansion or dissolution in the PVC-O-polyurethane tube's surface. This allows extrusion pressure to unite these surfaces during socket insertion. The adhesive's solvent easily volatilizes, reverting the dissolved surface to a solid state, maintaining substrate strength and ensuring that the bonding strength meets pressure requirements.
Adhesive quantity should be precisely controlled; it must be neither too scant to compromise sealing and strength, nor excessive, which may flow along pipe walls, corroding and softening them. Overuse leads to cracking under water or pressure. In cold conditions, slowed adhesive volatilization increases penetration, weakening the pipe wall.
Adhere strictly to specification requirements for bonding pipe construction. Ensure adhesive application results in minimal overflow when the socket is inserted, which should be promptly cleaned off. Apply glue from the socket interior outward to avoid unwanted flow into the pipe internals.
4. Considerations for Thermal Expansion and Contraction of Pipes
With a thermal expansion coefficient of 0.07mm (m · ºC), PVC-O water supply pipes expand more than traditional materials. Take into account temperature-induced longitudinal deformation, especially in systems utilizing surface water sources.
Thanks to the versatile scalability of the rubber ring connecting pipe interface, the issue of expansion or contraction is effortlessly mitigated. However, when it comes to bonded pipes, especially the open type, post-bonding, the interface becomes rigid, lacking flexibility. Without installing expansion joints, the immense pressure from expansion or contraction could severely impact the pipe structure or fittings.
Explore a world of connection methods with our versatile pipes, offering the flexibility of solvent adhesive, elastic sealing ring, and integrated rubber ring connections. Furthermore, these pipes seamlessly connect to other varieties like cast iron pipes through the use of flanges or other compatible adapters, providing a comprehensive solution for diverse piping needs.
Effortless Connection Program: Begin by meticulously cleaning the working face ---- Next, apply a lubricant generously ---- Finally, ensure a precise counterpart insertion for optimal performance.
1. Prior to installation, meticulously verify the quality of pipes, fittings, and rubber rings. Ensure the working face of both the socket and its counterpart are spotless and ready for a seamless assembly.
2. During installation, strategically position the socket towards the direction of incoming water flow, optimizing the system's efficiency and reliability.
3. Generously apply lubricant to both the rubber ring and the insertion section. While ensuring moderation in your application, this measure prevents the lubricant from seeping into the socket groove, which could otherwise disrupt the assembly. This strategic application reduces friction between the rubber ring and the groove wall, effectively safeguarding against any potential overturning of the rubber ring. For optimal results, we recommend the use of detergent and soapy water as lubricants, providing a smooth and seamless installation experience.
4. Align the socket ports with precision, ensuring that the pipeline axis maintains perfect linearity. This precise alignment is crucial in guaranteeing stability and structural integrity throughout the installation, promising a robust and long-lasting connection.
5. Secure the socket's positioning by equipping both sides with appropriate wire rope sleeves. Utilize a tightener or a hand wrench to pull the sleeves securely into the reticle. For medium-caliber pipes, position square wood at the port and tap it gently into the socket with a mallet. This technique ensures a precise and snug fit that enhances the reliability and efficiency of the entire system.
