Sheet Pile Repair and Reinforcement

At present in the world methods of sheet pile repair and reinforcement mainly include two categories : Local Repair and Reinforcement Method and Set Alternative Retaining Structure Method.

Local Repair and Reinforcement Method includes : Steel Repair and Weld Method, local Outside Cover Reinforcing Method, Lower Beam Cover Elevation Method and Improve Soil Properties behind the Wall Method;

For Method of Setting the Alternative Retaining Structure includes : Add Underground Continuous Wall Method and Add Alternative Steel Sheet Pile Method.

Which Method to Use

Due to technical conditions, the actual project cases of steel sheet pile structure repair and reinforcement are very few.  For research, we suggest use ANSYS software to build simulation models for structure reinforced, compare deformation, internal force and stress produced by all reinforcement methods to discuss and analyse the technical feasibility and reliability of these repair and reinforcement methods.

Why Need Sheet Pile Reinforcement and Repair

With strong capacity, watertight and simple to use and good durability etc., sheet pile of steel become the mainstream materials in modern construction industry.In the harbor or port's shore structure which used to connects wharf structure and slope as sheet pile retaining,steel sheet pile itself is vulnerable to erosion and damage. So we need to repair and reinforce sheet piles.
