Detailed Route Planning for the Sot Salt Chemical New Brine Pipeline Project (Second Price Comparison)

1. Price Comparison Conditions
Sote Salt Chemical Co., Ltd. plans to construct a new brine‑transport pipeline and is required to prepare a detailed master plan aligned with the overall urban development plan of Wanzhou District, based on the preliminary site survey conducted by the project developer. The plan must also appropriately avoid existing underground utility networks, railways, bridges, expressways, and other critical surface structures. The project owner is Chongqing Sote Salt Chemical Co., Ltd., with funding to be self‑financed. All conditions for price comparison have been met, and a competitive bidding process is now being initiated for the preparation of this detailed master plan.
2. Project Overview and Scope of Price Comparison
2.1 Project Location
Gaofeng Subdistrict—Shuanghekou Subdistrict—Longdu Subdistrict: Gaofeng Changyan Mine (buried pipeline installation)—Gaofeng Middle Road (buried pipeline installation)—Gaofeng Lingfeng Mountain (directional drilling crossing)—Mengzi East Road (buried pipeline installation)—Qinggangbang Interchange (pipe-jacking crossing)—Changqing Road (pipeline support installation/overbridge utility tunnel installation)—Sote Salt Chemicals’ salt‑making workshop.
2.2 Project Overview and Technical Proposal
Chongqing Sote Salt Chemical Co., Ltd. plans to construct a new Φ530 mm brine‑transport pipeline, which will be laid underground in a common trench. The pipeline will run from the Gaofeng Field rock‑salt mine in Gaofeng Subdistrict to the salt‑production workshop within Chongqing Sote Salt Chemical Co., Ltd. in Longdu Subdistrict. The entire route lies within Wanzhou District, Chongqing, passing through Gaofeng Town, Shuanghekou Subdistrict, and Longdu Subdistrict, with a total length of approximately 11.8 km.
In the non‑directional drilling crossing section, Φ530 mm steel‑reinforced polyethylene composite pipes are joined using specialized electrofusion fittings; these pipes are installed either underground, on pipe supports, or within a pipe rack (for the bridge‑underpass segment). In the directional drilling crossing section, straight‑seam submerged‑arc welded steel pipes are employed, with a high‑temperature‑resistant PE liner. The PE liner is bonded to the inner surface of the seamless pipe under high pressure, and flanged connections are used at both ends of the directional drilling crossing. The design pressure is 2.0 MPa.
