T/CEC 5021-2020 Technical Specifications for Rock-embedded Pile Projects of Overhead Transmission Lines
T/CEC 5021-2020
Basic Information
Scope
1.0.1 In order to unify the investigation, design, construction, inspection, and environmental protection of rock-embedded piles for overhead transmission lines, and to improve the construction level of rock-based transmission line projects, these standards are formulated. 1.0.2 These standards apply to the investigation, construction, design, inspection, and environmental protection of rock-embedded piles for overhead transmission lines. 1.0.3 These standards define the design principles for rock-embedded piles for overhead transmission lines and provide design calculation methods for tower-embedded piles. 1.0.4 The design of rock-embedded piles for overhead transmission lines should proceed from reality and actively adopt new technologies, new processes, new equipment, and new materials. It is necessary to promote the application of advanced energy-saving, consumption-reducing, and environmentally friendly technologies and products. 1.0.5 When designing rock-embedded piles for overhead transmission lines using new theories, new materials, or new structural forms, and when there is a lack of practical experience, verification through testing is required. 1.0.6 The investigation, design, construction, inspection, and environmental protection of rock-embedded piles for overhead transmission lines shall comply with the provisions of these standards, as well as the relevant current national standards.
