Underground comprehensive pipe gallery grounding connection structure and pipe gallery construction method
The invention discloses an underground comprehensive pipe gallery grounding connection structure and a pipe gallery construction method.According to the common grounding connection structure, through welding and fixing of a first connecting piece, a second connecting piece and a third connecting piece, a supporting column, a steel bar square grid and a grounding grid form the comprehensive pipe gallery common grounding connection structure, and the middle of the third connecting piece comprises a water stop piece. The comprehensive pipe gallery adopting the structure has the following advantages: 1, the supporting piles are assisted by the reinforcing steel bar square grid to improve the structural strength, the supporting piles are electrically connected with the grounding grid and the comprehensive pipe gallery to ensure that the common grounding resistance meets the design requirement and is lower than 1 omega, the durability is good, and the redundancy is high; 2, the third connecting piece is provided with a water stop belt, so that the self-waterproof structure of the comprehensive pipe gallery is prevented from being damaged; and 3, when the grounding grid structure is easy to lose efficacy due to settlement of the comprehensive pipe gallery, the grounding device formed by the support piles and the steel bar square grid can also play a role of a grounding device, and safe use of electrical devices in the operation and maintenance stage of the comprehensive pipe gallery is ensured.
本发明公开了一种地下综合管廊接地连接结构及管廊施工方法，此共用接地连接结构，通过第一、第二、第三连接件的焊接固定、以使支护柱、钢筋方格网及接地网形成综合管廊共用接地连接结构，其中第三连接件中部包括止水片。采用上述结构的综合管廊具有如下优势：1、将支护桩辅以钢筋方格网提升结构强度与接地网、综合管廊进行电气联结，确保共用接地电阻符合设计要求低于1Ω、耐久性好、冗余度高；2、第三连接件设有止水带，以避免破坏综合管廊自防水结构；3、当综合管廊因沉降易使接地网结构失效，支护桩和钢筋方格网构成的接地装置也能起到接地装置的作用，确保综合管廊运营维护阶段的电气装置安全使用。
