Abstract

The invention provides a comprehensive grounding system of a shield method comprehensive pipe gallery. A lower supporting cushion layer is arranged on the inner side of the lower portion of a shield tunnel. A middle partition plate is mounted above the lower supporting cushion layer; a duct piece grounding connecting plate pre-buried on the shield duct piece is electrically connected with a reinforcing mesh in the shield duct piece; a cushion layer grounding connecting plate pre-buried on the surface of the lower supporting cushion layer is electrically connected with a grounding steel bar grid I in the lower supporting cushion layer; the grounding steel bar grid I in the lower supporting cushion layer is electrically connected with the duct piece grounding connecting plate; a middle partition plate grounding connection plate pre-buried on the surface of the middle partition plate is electrically connected with a grounding steel bar grid II in the middle partition plate; the cushion layer grounding connecting plate is electrically connected with the middle partition plate grounding connecting plate; a transverse grounding main line is arranged in the upper cabin of the pipe gallery, the pipe piece grounding connecting plates are electrically connected through the transverse grounding main line, and the two ends of the transverse grounding main line are electrically connected with the cushion layer grounding connecting plates. The construction speed can be increased, raw materials are saved, and the reliability of a grounding system is improved.

Description

technical field [0001] The invention belongs to the field of building electrical technology, and in particular relates to a comprehensive grounding system for a shield tunneling comprehensive pipe gallery.
