Abstract

The invention discloses an immersed tunnel comprehensive grounding device. The grounding devices are disposed on a reinforcement framework at an interval. The device comprises a bottom steel plate waterproof layer, multiple bottom steel plate anchor bars which are fixedly connected to the bottom steel plate waterproof layer, and a bottom plate annular steel bar which is fixedly connected through welding to at least the two bottom steel plate anchor bars. An installation method of the immersed tunnel comprehensive grounding devices is characterized in that the grounding devices are disposed onthe reinforcement framework at the interval and comprises the steps that the bottom steel plate waterproof layer is disposed on the bottom of an immersed tunnel section; the bottom steel plate waterproof layer is fixedly connected to the bottom steel plate anchor bars; the bottom plate annular steel bar is fixedly connected to the bottom steel plate anchor bars; the bottom plate annular steel baris fixedly connected to a vertical steel bar by an inclined steel bar; and the grounding devices are disposed vertically on the immersed tunnel section at an interval of 20-25m. The device and the method disclosed by the invention are applicable to direct grounding of a long and large immersed tunnel and have good comprehensive grounding effects.

本发明公开了一种沉管隧道综合接地装置，接地装置间隔设置在钢筋骨架上，包括：底钢板防水层；多个底钢板锚筋，与底钢板防水层固定相连；底板环向钢筋，至少与两个底钢板锚筋通过焊接固定连接在一起。一种沉管隧道综合接地装置的安装方法，将接地装置间隔设置在钢筋骨架上，包括以下步骤：在沉管管节的底部设置底钢板防水层；将底钢板防水层与底钢板锚筋固定连接在一起；将底板环向钢筋与底钢板锚筋固定连接在一起；将底板环向钢筋通过斜向钢筋与竖向钢筋固定连接在一起；在沉管管节的纵向上每间隔20～25m设置接地装置。本发明适用于长大沉管隧道直接接地，综合接地效果好。
