New Shanxi south central railway corridor is national planning capacity coal transport channel construction project, is a national key project, the starting point for the Shanxi Province, Luliang City Xingxian tile Tang Zhen, the end of the Rizhao Port, 1260 kilometers in length, including 75.4 km of territory of Rizhao City, projects with a total investment of 998 million yuan, plans to in September across the board through 2014. South Central Railway Corridor construction, to ensure national energy supply and economic development has an important role, enough close Shanxi, Henan and Shandong provinces of regional economic cooperation, along to accelerate social and economic development.
Since the beginning of December 2012, Shanghai Jintai engineering machinery company has 4 sets of SH30W multi functional rotary drilling rig in South Central Railway Rizhao Donggang District field operations. In the face of 1 000 mm in diameter and 34 meters deep into the pile, 4 sets of SH30W to enter the site, December 4, began drilling construction, as of January 21, 13 years, the effective working time of 15 days (and only for construction at night), pile 156 root, average efficiency for 3 / number. According to the introduction, the local strata structure is complex, underground 17.9m-26.7m is strongly weathered gray green granite, 26.7m the following is 80Mpa weak weathered granite. On the rock and the compressive layer and other several well-known domestic manufacturers of similar rotary drilling rig is showing different conditions, equipment and some dry repair, troubled, affect the duration and efficiency; some equipment directly stop on the side, unable to normal operation. In contrast, Kim Tae SH30W multi-function driller, reliable performance, the indicators are meet the design requirements, high construction efficiency, fill the engineering task by spoke highly of the project department. The project department according to the outstanding performance of SH30W in terms of construction, the final decision of this section to the pile foundation construction products.
