Description
PHC pipe piles can be used in construction on soft soil foundations and for special engineering projects; the dataset includes key primary and auxiliary materials, energy consumption, and atmospheric emissions from the production process, but infrastructure such as production equipment and factory construction is not included within the system boundary of the dataset; the life cycle inventory is compiled from data obtained from multiple sources; the manufacturing process of PHC pipe piles consists of several steps, including component assembly and mixing, secondary batching, mold feeding, mold closing, prestressing tensioning, centrifugal forming, steam curing in pools, detensioning, demolding and compressive strength testing, and autoclave curing.
Activity Description
The production activities of this product include pile head plates, cage reinforcement, joint assembly; mold preparation, mold release agent spraying, concrete batching and mixing, secondary weighing, feeding into mold, mold closing; prestressing tensioning, centrifugal forming, steam curing in tanks; pressure release, demolding, compressive strength testing, autoclave curing, and other processes.
Process Description
PHC pipe piles have high single-pile bearing capacity, excellent resistance to driving stress, strong penetration capability, and strong adaptability to geological conditions with variable pile end bearing strata. This product is suitable for general cohesive soils, sandy soils, and strongly weathered rock, especially in soft soil foundations, and is also applicable to various types of building foundations such as high-rise and multi-story buildings, large-span structures, industrial plants, and special engineering projects.
