Recently, a Yuchai YCR405E rotary drilling rig appeared at the construction site of the Lixian Expressway in Pengjiagou Village, Tangya Town, Xianfeng County, Enshi City, Hubei Province, participating in the construction of the Huangheba Grand Bridge project.

YC Efficient

The Huangheba Grand Bridge project is located in the Wuling Mountain area, mostly karst topography, with hard and complex strata dominated by karst caves, inclined rock, and boulders, making construction difficult and technically demanding. The construction pile diameters are mainly 1.5 meters and 2.5 meters, with drilling depths ranging from 30 to 55 meters, subject to design requirements. The newly upgraded Yuchai YCR405E rotary drilling rig adds a fast pressurization function, which can quickly adjust the position of the power head, improve hole alignment speed, and enhance construction efficiency. Its hydraulic telescopic crawler chassis specially designed for rotary drilling rigs is equipped with a large-diameter slewing bearing, and the platform main beam uses high-strength steel, making the structure more stable and reliable and ensuring construction stability. Since entering the site, the Yuchai YCR405E rotary drilling rig has attracted much attention from the project department; from fuel consumption to construction efficiency, its superior construction performance has been highly recognized by the project department.

YC Productive

It is reported that the Lixian Expressway starts at Tian'e Pond in the west of Lichuan City, Enshi City, Hubei Province, and ends near Xiaomo Village, Gaoluoshan Town, Xianfeng County, connecting with the Xuanxian Expressway under construction. The Lixian Expressway is an important part of Hubei Province's "nine vertical, five horizontal, four ring" expressway network. After the project is completed, the driving distance from Lichuan to Xianfeng will be greatly shortened from the original 2.5 hours to 1 hour, which is of great significance for building a vertical rapid corridor in the adjacent areas of Hubei, Hunan, and Chongqing and promoting regional rural revitalization and economic and social development.
