Embodiment Construction
[0036] The present invention is described below in conjunction with accompanying drawing.
[0037] The present invention relates to a soft soil foundation treatment and construction method of a mixing pile anti-floating anchor rod, in particular to a new combination of foundation treatment and anti-floating technology, which mainly consists of two parts, including: cement-soil mixing pile 1 and The barbed anchor 2 and the bottom of the cement-soil mixing pile 1 pass through the muddy silty clay layer 3 and then reach the silty clay 4 .
[0038] Construction technique of the present invention and matters needing attention are as follows:
[0039] 1. Construction process
[0040] Construction preparation → pile driver in place → driving cement-soil mixing piles → insert anchor rods from the construction ground before the initial setting of cement and soil, and end at 100mm from the bottom of the mixing piles → grouting → cut off excess steel pipes at the design elevation of the...
