The application of shape steel pile in foundation pit support;

The design and construction of steel H Piles by driving method in one project in Hong Kong is introduced,in which ground investigation,design and construction procedure,determination of bearing layer and pile bottom level,calculation of bearing capacity,considerations on particular cases,and static loading test are included.

Base on the analysis of reason for differential settlement of certain building,the micro steel tube piles are used to consolidate it,and the result is fine.

Drag exchange and reinforcement original old cap with micro steel tube pile and anchor technology of reinforcing bar, it was used very few in drag exchange construction of foundation of China.

The composite foundation, which is composed of micro-steel pile and soil improved by compaction grouting, can meet the bearing capacity demand of upper structure.

By making use of combat readiness boat & bridge equipment in the construction of Tianjin rainbow bridge, the construction technique, the key points ,main performance of equipment ,quality control of large scale steel stake cofferdan quality are introducd.
