More Than 30 XCMG Rotary Drilling Rigs Entering Chongqing Traffic Hub Project
More than 30 XCMG rotary drilling rigs entering Chongqing Traffic Hub Project
Recently, the pile foundation construction of Chongqing East Railway Station Comprehensive Transportation Hub Project is hot. More than 30 rotary drilling rigs were deployed to "take root" downward, tamping the foundation platform and erecting beams for the first comprehensive transportation hub new city in Chongqing.
The construction of Chongqing East Railway Station Hub New City is a complex systematic project with complex geology, strict requirements and urgent time. There are more than 20 construction units in the whole area and more than 20000 constructors in the peak area. More than 30 XCMG rotary drilling rigs were present at the same time, and the project equipment accounted for nearly 70%.
The rotary drilling machines involved in this construction are XCMG E-series XR280E and XR360E. It is necessary to drill pile holes with a diameter of 1.5m and a drilling depth of 20m on sandstone and limestone strata to facilitate the later concrete pouring.
The XCMG rotary drilling rig is faced with a hard to hard competition. The pile foundation construction needs to go through multiple processes such as positioning survey, drilling and hole forming, hole cleaning and hole forming quality inspection. The XCMG rotary drilling rig has demonstrated excellent performance. Drilling and soil throwing are carried out in one go. Three piles are formed every day. On average, a pile can be formed within 7-8 hours, and the pile quality is excellent.
In addition to the overall improvement of construction efficiency, XCMG has comprehensively improved the energy saving and efficiency enhancement of rotary drilling rigs participating in this construction. More than 30 sets of "XCMG Gold" were constructed at the same time. The scene was spectacular and looked down from high, just like "giants". With the pile foundations erected one by one, the rudiment of a super "base" supporting the Chongqing East Railway Station hub has first appeared.
