含玻璃纤维(GFRP)筋地下连续墙施工监理控制要点

Control Gist for Construction and Supervision of Glass Fiber Reinforced Polymer(GFRP) Bar Underground Diaphragm

玻璃纤维(GFRP)筋作为一种新型材料代替钢筋应用到盾构工作井洞门区地下连续墙围护结构中与普通钢筋混凝土地下连续墙相比有其特殊性。该文主要介绍了上海长江隧道工程长兴岛工作井监理工程师在含玻璃纤维筋的地下连续墙的施工过程中的质量与安全控制要点,为提高类似工程的监理水平提供借鉴。

GFRP bar taken as a new material replacing the steel bar is used in the enclosing structure of the underground diaphragm of the shield working shaft tunnel portal.Its particularity is compared with the common steel reinforced concrete underground diaphragm.The article mainly introduces the quality and security control gist in the course of GFRP underground diaphragm of Changxing Island working shaft supervision project of Shanghai Changjiang River Tunnel Project,which can be referred for the similar projects.
