Secant piles construction method Casing Rotator

The occlusal pile foundation construction method of full rotary drill,also called Casing Rotator  is a common pile foundation construction method, which is suitable for pile foundation construction under various geological conditions. The specific construction method is as follows:

 First, the full rotary drill is used to drill holes on the pile position and drill the pile holes to the depth required by the design.

 Install a steel cage in a borehole and reinforce it according to the design requirements.

 Pour concrete from the top of the pile hole and pour layer by layer to ensure enrichment and compaction.

 In the process of pouring concrete, the vibrator is used to vibrate the concrete, eliminate bubbles, and improve the compactness and strength of the concrete.

 After the concrete solidifies, the pile top is trimmed to ensure that the pile top is smooth.

 The pile body is tested to ensure that the quality of the pile meets the design requirements.
