Construction Technology and Quality Control of Rotary Drilling Rig
With the rapid development of economic construction, bored cast-in-place piles are increasingly used in foundation engineering for civil buildings, highways, urban viaducts, high-speed railways, and wharves. Their application in large and medium-sized bridges for highways, urban viaducts, and high-speed railways has become increasingly important, which has also promoted the rapid development of construction technology for bored cast-in-place piles in bridges. In recent years, the rotary drilling rig has become a relatively advanced construction equipment for bored cast-in-place pile construction. Its main feature is high construction efficiency, making it suitable for projects with tight schedule requirements. From June 2008 to December 2009, it played a full role in the pile foundation construction of Section 1 of the Beijing-Shanghai High-Speed Railway and Section F01 of the Taizhou Bridge. At the same time, it enabled on-site technical personnel to further master the construction technology, accelerated the construction progress, and ensured project quality.
