Trench Excavation Standards for PVC-O Water Supply Pipes and Optimal Backfill Soil Quality
1. Embrace the highest industry standards for trench excavation, which is a pivotal element for the efficient and successful installation of your water supply system, ensuring long-term reliability.
Prevent the risk of pipeline disturbances caused by permafrost layers by diligently determining trench excavation depth through comprehensive analysis of local geological data. This meticulous planning facilitates seamless backfill operations, vital to avoiding pipeline and interface cracking from bending stress. Key specifications include:
(1) Trenches must be impeccably straight, with a bottom width exceeding the pipe's outer diameter by 0.5m, ensuring total trench width is no less than 0.7m for enhanced stability and support.
(2) Maintain precise bottom depth, steering clear of extremes. In scenarios of excessive gravel depth, backfill and compact according to specifications. Should you encounter hard soil or obstructions such as stones, slight trench curvature aids construction. Ensure these curves are gentle and maintain consistent depth to prevent pipe bending, which could impose undue stress on the pipe, fittings, and joints, increasing the risk of joint leakage or rupture due to elevated water pressure.
2. Protect against permafrost-related foundation instability and potential trench settlement. During winter, ensure that pipe trenches are situated on undisturbed soil or well-compacted backfill. High soil moisture can lead to future permafrost melt and trench settlement, risking pipe sinking, bending, and joint failure under stress, where even minor issues may lead to joint separation and leaks, and severe instances could cause rupture.
3. Conform strictly to all regulations regarding winter pipeline bonding to ensure connections are robust and reliable under all conditions.
PVC-O tube adhesive, mainly constituted by PVC-O solvent, works by applying adhesive to the socket's inner and outer surfaces, prompting expansion or dissolution on the PVC-O-polyurethane tube's surface. This process facilitates seamless surface union upon socket insertion through extrusion pressure. The adhesive's solvent evaporates rapidly, restoring the surface to a solid state, maintaining substrate integrity and ensuring bonding strength withstands pressure demands.
Adhesive quantity must be meticulously regulated-neither too little to compromise sealing and strength nor too much, which could flow along pipe walls, causing corrosion and softening. Overuse may result in cracking under water pressure. In cold conditions, slower adhesive evaporation heightens penetration risks, compromising pipe wall integrity.
Adhere strictly to specification requirements for bonding pipe construction. Ensure adhesive application results in minimal overflow during socket insertion and promptly cleanse any excess. Apply glue from the socket interior outward to prevent unwanted flow into the pipe's internals.
4. Strategic Considerations for Thermal Expansion and Contraction of Pipes
PVC-O water supply pipes, with a thermal expansion coefficient of 0.07mm (m · ºC), exhibit greater expansion rates compared to traditional materials. This necessitates accounting for temperature-induced longitudinal deformation, particularly in systems utilizing surface water sources.
The adaptable scalability of the rubber ring connecting pipe interface allows for seamless management of expansion or contraction issues. However, bonded pipes, especially in open types, post-bonding, result in a rigid interface void of flexibility. Absence of expansion joints could lead to significant impacts on pipe structure or fittings due to pressure from expansion or contraction.
Explore a wide array of connection methods with our pipes, offering the versatility of solvent adhesive, elastic sealing ring, and integrated rubber ring connections. These pipes also effortlessly connect to other types, like cast iron pipes, using flanges or compatible adapters, providing robust solutions for diverse piping requirements.
Effortless Connection Program: Start by meticulously cleaning the working face ---- Then, apply a lubricant generously ---- Finally, ensure precise counterpart insertion for optimal system performance, maintaining efficiency and reliability.
1. Before installation, thoroughly verify the quality of pipes, fittings, and rubber rings. Ensure that the socket and its counterpart are impeccable, setting the stage for a flawless assembly.
2. During installation, strategically position the socket to face the direction of incoming water flow, enhancing system efficiency and ensuring maximum reliability.
3. Generously apply a high-quality lubricant to both the rubber ring and the insertion section, ensuring every part is thoroughly covered. However, take care to use the lubricant sparingly to prevent any excess from seeping into the socket groove. This careful application is crucial, as it significantly reduces friction between the rubber ring and the groove wall, effectively preventing any potential overturning of the rubber ring. For optimal results, we recommend using mild yet effective lubricants such as detergent and soapy water.
4. With utmost precision, carefully align the socket ports to maintain the pipeline axis in a perfectly straight line. This meticulous alignment is essential for ensuring the pipeline's long-term stability and structural integrity, which are paramount for its efficient performance.
5. Secure both sides of the socket with robust wire rope sleeves and utilize a tightener or a hand wrench to pull them firmly into the reticle. For medium-caliber pipes, strategically position square wood at the port and gently tap it into the socket using a mallet. This method guarantees a precise, secure fit, enhancing the overall performance and reliability of the pipe installation.
