摘要
地下连续墙GXJ接头相比于普通锁口管接头具有更好的防渗漏性能和更小的施工风险,因此,GXJ接头正逐渐全面取代锁口管接头。但是原有的GXJ接头工艺在超深地下连续墙中使用仍存在着相当大的安全风险。在这一背景下,对原GXJ接头箱体及侧向取出工艺采取了一些改进措施,使得GXJ接头在厚800mm地下连续墙中的应用取得了成功。
Compared with the common lock pipe joint, the GXJ joint of the underground diaphragm wall has better anti-seepage performance and less construction risk. Therefore, the GXJ joint is gradually replacing the lock pipe joint in an all-round way. However, there are still considerable safety risks in the application of the original GXJ joint technology in the ultra-deep diaphragm wall. Under this background, some improvement measures have been taken to the original 800 mm thick GXJ joint box and lateral removal technology to make the application of GXJ joint in 800 mm thick diaphragm wall successful.
