"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).

basic information
Example: Confluence Box (Large Special Item) Size: Internal dimensions 3000*5300*1600H (3-part) Features: To enable manufacturing with precast methods, the large box is produced in three parts. (If it were a single unit, delivery would be impossible even with a large truck.) ● Installation is considered, and delivery is handled with a 7-ton truck. (Due to the site being a narrow area.) ● Connection between products is done using "flange connection," and sealing materials are attached at the joints. ● To consider water stopping, "joint bags" are provided. → Joint filling with materials like high mortar is to be done on-site. ● Addressing "buoyancy" issues with the installation of weep holes. ● To stabilize the installation, the lifting positions are calculated for flat installation. ● Structural calculation documents can also be submitted. *As this is a custom product (wood frame), there are allowable tolerances.
