Application for Movable Lattice Grid Platform Construction Technic in the Bare Rock Stream Bed Area

It is very important to how to deal with construction platform on the water,when the water level state is terribly unstable and routine steel tube pile platform or floating platform can not be used during the construction of bridge on the water.Author introduces a method how to make use of steel tube bearer to set construction platform and finish pile foundation construction successfully in the complicated hydrogeological condition area via construction experience of Nanping large river bridge.This is a movable lattice grid used time and again,which can both reduce cost to great extent and guarantee safety and quality of construction,this is an advanced construction technics that is worthy of spreading.
