Sea walls (designed as reinforced soil walls) with vertical concrete facings combined with fully synthetic reinforcements and connections

摘要

In order to offer a coherent earth reinforcement system suitable for the most highly chemically aggressive fills (as for sea walls) a fully synthetic system ( reinforcements and connections to panels) combined with vertical facing panels has been developed. This paper describes the development of a new fully synthetic method of fastening main reinforcements to panels and then several practical applications. This system is based on the use of fully synthetic main reinforcing strips. The innovation consists of the new generic methods of fastening the reinforcements to panels made with : Synthetic continuous loop which is half embedded inside the concrete facing panel and half protruding in the form of two external handles. Synthetic toggle in Pultruded Glass Fibre around which the main reinforcing strip is folded and anchored. To date a total area of facing of more than 110,000 m~2 has been successfully built. The main advantages of this system are the use of locally available fill and the efficiency of vertical concrete facings.
