Improved cast-in-place pile construction casing
The invention provides an improved cast-in-place pile construction casing. The casing is a steel casing and consists of a casing body and a grouting pipe parallel to the casing body. The device has a simple structure and is convenient to use, the lift force at the time when the casing is pulled out of a spiral borehole can be reduced, the lift efficiency of a crane is improved, the casing can be repeatedly utilized for a long time, and the construction cost is greatly saved.
