Salt lake area power transmission line iron tower foundation construction method

Abstract

The invention belongs to the technical field of power transmission line iron tower foundation design, and particularly relates to a salt lake area power transmission line iron tower foundation construction method. The construction method comprises the following steps that S1, a foundation pit is excavated, and the foundation pit is treated in a composite foundation treatment mode; S2, a foundation structure is optimized, a primary beam structure and a secondary beam structure are added on a foundation bottom plate, and the foundation structure is designed into an integral foundation type; S3, glass fiber reinforced plastics are adopted for carrying out wrapping anti-corrosion treatment on all parts of the foundation structure; S4, soil covering treatment is conducted on the foundation pit, and protection treatment is conducted on a tower footing slope; and S5, waterproof treatment is conducted on the base face of the tower footing. The method systematically solves the problems of foundation instability and salinized soil corrosion of the power transmission line iron tower in the salt lake area, ensures safe and stable operation of the power transmission line, and has important significance for improving the economical efficiency and the safe stability of industrial production in a salt lake mining area and promoting sustainable and healthy development of the industrial production in the salt lake area.

Description

technical field [0001] The invention belongs to the technical field of transmission line iron tower foundation design, and in particular relates to a construction method for the transmission line iron tower foundation in the salt lake area. Background technique [0002] The Salt Lake area is an important industrial production area in my country. In the early days, a large number of structures such as power, transportation, industry, and civil buildings were built for the development of industrial production in the Salt Lake area. In recent years, building safety hazards caused by basic problems have frequently occurred. The reason is that As a building foundation, the saline soil in the salt lake area has the characteristics of dissolution, strong corrosion, high compressibility, low shear strength and low bearing capacity. In the early days, foundation treatment methods such as crushed stone pile method, surcharge method, and dynamic compaction method were commonly used. To i...

[0002] The Salt Lake area is an important industrial production area in my country. In the early days, a large number of structures such as electric power, transportation, industry, and civil buildings were built for the development of industrial production in the Salt Lake area. In recent years, building safety hazards caused by basic problems have frequently occurred. The reason is that As a building foundation, the saline soil in the salt lake area has the characteristics of dissolution, strong corrosion, high compressibility, low shear strength and low bearing capacity. In the early days, foundation treatment methods such as crushed stone pile method, surcharge method, and dynamic compaction method were commonly used. To improve the bearing capacity of the foundation, granite, outsourcing steel plates, additives, coatings and other materials are often used to improve the corrosion resistance of structures, which has been proved to be ineffective

[0003] At present, domestic research on saline soil in the salt lake mining area has not yet formed a specific theoretical system. The foundation design of transmission line towers in the salt lake area is mostly focused on foundation treatment, without considering the industrial environment in the salt lake area, climate change under the influence of the greenhouse effect, and foundation Therefore, it is necessary to adopt a new foundation treatment and foundation construction method
