模袋砼施工技术在河道防护工程中的应用

Application of Construction Technique of Mould-bag Concrete in River Course Protection Project

用高强机织土工模袋布缝制成模袋，并在其中充灌砼（或砂浆）而成型的模袋砼是一种新型的防护用混凝土。该项施工技术在深圳河罗湖铁路桥河道防护工程中，得到了成功的应用。本文简要介绍了模袋砼施工技术的技术要点，并结合罗湖桥防护工程施工情况。

Mould-bag is stitched by using machine weaved earthwork cloth with high strength .Mould-bag concrete is a new type protecting concrete which is moulded by filling mould-bag with concrete (or mortar).This construction technique has achieved successful application in river course protection of Luo-Hu Railway Bridge on Shenzhen River.This paper describes the main points of this construction technique.In conjunction with the situation,it also describes the operation procedure of this technique and problems to be noticed.
