Construction process of retaining wall with inner anchoring wall

The invention involves a method used to build a kind of blocking soil wall by use of inner anchor wall. One or multi anchor walls are built within blocked soil mass to provide stretching resistance for anchor rod and anchor line. The inner anchor wall, anchor rod and anchor line, outer locking wall together form a blocking soil wall to clamp blocked soil mass. The outer blocking wall is mainly made from stirred cement pile. The inner anchor wall is mainly made from vertical steel pile, from horizontal seizing & expanding dish supporting pile or horizontal stirred cement pile. Because of easy and simple construction of the inner anchor wall, high anchor-hold of the ground anchor and being reused of the anchor rod and the anchor line, the cost is lowered to 50% and constructing time is shortened to half period of original one. Moreover, the stress situation is clear and designing calculation is simplified for such form of structure.
