YongMeng Expressway Electromechanical and Traffic Safety Project

The YongMeng Expressway Electromechanical and Traffic Safety Project, undertaken by the Third Engineering Project Department, covers the construction of traffic safety facilities, monitoring systems, communication systems, fire systems, power supply and distribution, lighting systems, and ventilation systems within the YongDe connecting line stake number. Currently, the construction tasks within the stake number of the traffic safety facilities project on the YongMeng Expressway Electromechanical and Traffic Safety Project connecting line have been completed, and the initial acceptance inspection organized by the owner has been completed. In terms of electromechanical engineering, the installation of cables for the monitoring system, communication system, tunnel lighting, tunnel ventilation system, and tunnel power supply and distribution system has been completed, and the tunnel power supply and distribution and lighting systems have been put into use.

NanYun Expressway Construction Power Supply Project

The NanYun Expressway Construction Power Supply Project, undertaken by the Third Engineering Project Department, has completed the excavation of 50 tower bases, pouring of 50 tower bases, and erection of 29 towers for the 2.35kV ZhongMao line T-junction line; the 3.35kV temporary substation has completed the pouring of the primary and secondary compartments, the construction of the accident oil pool, the pouring of the lightning rod foundation, the construction of 800X800 and 600X600 cable trenches, the grounding system, and the construction of the external and internal drainage ditches.

YongChang Expressway YongLin Combined Power Supply Project

The YongPing to ChangNing Expressway (ChangNing section) franchise project power construction project, undertaken by the Eleventh Engineering Project Department, is located in ChangNing County, Baoshan City, passing through 耈 Street Township, Mangshui Town, ending at JiuJia in ChangNing County, connecting to the ChangLian Expressway, and intersecting with the ChangBao Expressway, with a total route length of 45.618km . This project will build two 35kV substations, 49 kilometers of 35kV transmission lines, 71 kilometers of 10kV transmission lines, and install 48 new transformers. Currently, the project has received the bid notification and is promoting contract signing and construction preparation work.

NanYun Expressway Steel Arch Frame and Small Conduit Production and Processing Project

The NanYun Expressway steel arch frame and small conduit production and processing project, undertaken by the Metal Structure Processing Center, currently supplies steel arch frames for five tunnels: Wuliang Mountain, Yinghua Valley, Zhoujia Village, Bingling River No. 1, and Yunzhou. Among them, Yinghua Valley Tunnel, Yunzhou Tunnel, and Bingling River No. 1 Tunnel have been fitted with arch rings. A total of 447.275 tons of steel arch frames have been supplied, with 8349.418 tons of I-beams and 6709.698 tons of steel bars in storage. Steel arch frames will be supplied to the Daliangzi Tunnel after the festival, with a planned supply of 12,000 tons of steel arch frames for the six tunnels.

Yuanda Expressway Project YongLin Combined Power Transmission and Transformation Engineering Power Second Division Project

As of now, the Yuanda Expressway 35KV line power transmission and transformation project Phase 2 has completed the excavation of 75 pole pits, excavation of 103 tower bases, steel bar binding of 99, pouring of 90 foundation concrete, erection of 50 towers, erection of 68 poles, installation of 46 fittings, and laying of 1.24km of conductors. It is planned to complete the laying of 35kV conductors, the remaining foundation pouring of 10kV lines, tower erection, transformer installation, and construction of substation No. 2 in July.
