Description

Technical Field

[0001] The utility model specifically relates to a cable crossing bridge for a river. Background Technique

[0002] The equipment for highway bridge construction needs to be driven by electricity, so electricity is essential during the construction process. Temporary electricity must be led out through a transformer and connected to the first-level, second-level, and third-level distribution boxes to meet the electricity demand at the construction site.

This way not only increases the disassembly and assembly workload before and after construction, but also affects electrical transportation, and there are problems such as poor safety.

[0004] Therefore, it is necessary to invent a cable crossing bridge for a river to solve the above problems. Content of the Utility Model

[0028] In this embodiment, the bottoms of the support frames 3 are positioned on both sides of the river and deeply inserted into the soil to ensure sufficient stability. The cable passing steel pipe 1 is spanned across the river and welded to the tops of the support frames 3 on both banks. The connecting rod 4 is installed in the middle of the fixed sections 31 at both ends, playing a role of transverse connection and support. A plurality of obliquely and crosswise arranged support square pipes 5 are respectively fixed on both sides of the connecting rod 4, forming a stable load-bearing structure at the bottom of the cable passing steel pipe 1.

[0030] Specifically, one end of each of the plurality of support square pipes 5 is fixed on both sides of the connecting rod 4, and the adjacent support square pipes 5 are staggeredly fixed. The other ends of the plurality of support square pipes 5 are fixedly supported on the bottom of the cable passing steel pipe 1 and are arranged obliquely as a whole.

[0031] Specifically, two sets of strengthening components 6 are provided and placed at both ends of the wire-passing steel pipe 1. Each set of strengthening components 6 includes two strengthening square pipes 61 fixed on both sides of the wire-passing steel pipe 1, and both ends of each strengthening square pipe 61 are respectively fixed on the same side of the wire-passing steel pipe 1 and the support frame 3.
