Construction of Cast-in-Place Piles Using Rotary Drilling Rigs
With the development of society, transportation has become increasingly convenient, and various expressways and rapid transit routes (elevated roads) are under continuous construction. As an important component of roads, bridge construction is also becoming increasingly important. The top priority in bridge construction is the construction of pile foundations, since only pile foundations of excellent quality can ensure the integrity and load-bearing capacity of bridges. To accelerate the pace of construction, shorten the construction period, and ensure civilized and environmentally friendly construction, the construction method generally adopted in the construction of bridge cast-in-place piles is the rotary drilling rig cast-in-place pile process, that is, rotary bored cast-in-place pile technology. Based on the construction of the Kunshan Middle Ring Expressway elevated road, the author describes the characteristics of rotary drilling rig cast-in-place piles and the entire process of cast-in-place piles, including several steps such as pre-construction preparation, drilling and hole formation, pouring underwater concrete, and pile formation. In addition, the construction and its corresponding
