But now, successful application for the pre-stress anchor technique in the same case has been gained by use of one construction method of "orifice ponding pouring" in the deep excavation pit supporting in Xiamen Postal Edifice, which can be taken for example on similar engineeri.

The craft and the method of blocking water and concreting are simplified by technological reform which speeds up the construction progress,guarantees seals quality,and accumulates the experience.

Technology of grouting and blocking water in fault broken zone;

Based on failure causation analysis on initial grouting and blocking water method,the grouting and blocking water method was adjusted in time,meanwhile the arrangement of drillholes was coordinated reasonably.
