This article in view of the water affinity platform project design question, through the location diagnosis, balances this principle of design with the conceptual design control stress, Uses topdown construction method The counter-pressure anchor rod static pressure pile, had achieved deals with issue which the ground and foundation synchronization completes.

The application of anchor static pressure pile in the building rectify partial and foundation reinforce

Excessive land subsidence occurred because of drainage consolidation and backfill loading for soft clay foundation of a workshop,static pressure grouting with sleeve valve pipe and anchor static pressure pile underpinning technique were adopted to consolidate the soft ground foundation,and the technical features,consolidation mechanism and construction technology were introduced in this paper.

In this paper,the slant recification prin-ciples of the method of anchor static pressure pile with digging out soil is described.

On application of anchor jacked pile in reinforcing and strengthening foundation

Application of anchor jacked pile in old Guangzhou Baiyun Airport reinforcement project

This paper respectively uses the method of expansion of cavity and FEM to analysis the soil compaction effect of anchor jacked pile while sinking,and compares the calculation result of the two methods by combining effect is valuable to the application of engineering.

The measures to reduce the compaction effect of static-bolt pile and its engineering application;

Based upon analysis of the reasons caused the inclination and uneven settlement of one commercial and living building in Shanghai the reinforcement method with static-bolt pile is introduced as well as the design and constructionmethod of inclined-soil digging in deviation rectification,which has a certain reference value for similar works.

Taking practical prestressed pipe pile as example the reasons caused the deviation of pipe piles are analyzed;at the same time according to the various geological conditions and deviation degrees different strengthening treatments are introduced,which include adding reinforced concrete core,pouring concrete-filled steel tubes and static-bolt pile and acquire good treatment effect.

To satisfy function requirements,engineers adopted the supporting,changing and extracting pile technology with anchor rod static pressure piles and steel frames and successfully changed 3.

Engineers tried to adopt the anchor rod static pressure pile technology in design of tower crane foundations and this technology can improve synthetical benefit of projects.

As a new technology in the improvement of foundation soils,anchored silent pile is more and more widely used in practice.

Reviewing the application and development of anchored silent pile in the past 20 - odd years, the author would like to show that this technology has vast prospect.

Through a practical example of rectification,the design principle of anchored silent pile is described.
