Converging manhole (large special item)
"Precast junction box" We have also accommodated precast products and custom-made "one-of-a-kind" items!
This product is a precast concrete structure designed to consolidate multiple inflow pipes into one and facilitate smooth flow downstream in systems such as large waterways. Through consistent production in a factory, it achieves extremely high quality and workability compared to on-site cast structures. ▪ It promotes smooth merging while suppressing turbulence, even for inflows from different angles and heights. (Weep holes can be installed) ▪ High strength and durability: Manufactured, cured, and shipped under strict quality control in a factory. ▪ Labor-saving and time-reducing construction: There is no need for formwork installation, reinforcement, concrete pouring, or curing period on-site. Backfilling and pipe connections can be done immediately after installation, significantly shortening construction time and minimizing impact on surrounding traffic. ▪ Flexible response to diverse connection needs: The factory can flexibly accommodate opening processing and drilling according to the type of inflow pipes (PVC pipes, flume pipes, etc.), pipe diameter, connection angle, and elevation differences (drop).
