Explanation: When laying cables at road crossings, the minimum depth of the cable trench is typically determined by engineering and safety standards. This depth is necessary to provide adequate protection for the cables from external forces, traffic loads, and environmental conditions. A depth of 1 meter is a common standard for cable trenches at road crossings.
This depth allows for proper insulation and protection of the cables, minimizing the risk of damage or disruption due to various factors such as vehicle traffic, soil movement, and weather conditions. It also facilitates easier maintenance and repair of cables when needed.
While specific requirements may vary based on local regulations, project specifications, and the type of cables being installed, the 1-meter depth is a widely accepted standard for ensuring the integrity and longevity of cable installations at road crossings.
