With the further development of our western development strategy and the gradual implementation of "power transmission from west to East" project, more and more line projects need to pass through northwest saline soil or salt lake areas. Corrosive ions, such as SO42-, Cl- and Mg2+, have high concentrations in saline soil areas in western China, and the climatic conditions are harsh, such as hot summer, dry and cold winter, little precipitation and strong ultraviolet radiation, which also accelerate the damage of concrete structures. The combined action of strong corrosion environment and bad weather conditions leads to the damage and destruction speed of concrete is obviously higher than that of concrete under general environmental conditions. Environmental erosion will cause concrete protective layer cracking, and even damage concrete components in serious cases, thus shortening the service life of concrete engineering, not only affects the function of concrete structure, but also reconstruction and maintenance will lead to considerable economic losses. At present, in order to solve the problem of short service life of concrete of transmission line tower foundation in saline soil area, a series of measures have been taken to ensure the service life of concrete structure in practical engineering, including spraying a layer of protective coating on concrete surface, or using high-performance concrete with low water-binder ratio and high density. Most similar measures are based on reducing the transmission performance of erosive ions in concrete to improve the durability of concrete. Therefore, instead of using high-performance concrete as a whole to build the tower foundation of transmission lines in saline soil area, it is more scientific, reasonable and economically feasible to adopt anticorrosive mortar technology on the surface of concrete to reduce the erosion of the concrete structure caused by erosion environment. In view of the strong corrosion in saline soil area, anticorrosive mortar for transmission line tower foundation is proposed to improve the impermeability and crack resistance of concrete, so as to improve the durability of transmission line tower foundation and make it suitable for the strong corrosion area. Technical realization elements: In order to overcome the above defects of the prior art, the invention provides an anticorrosive mortar for transmission line tower foundation.
A power transmission earth anchor is a device designed to provide a secure and stable foundation for power transmission towers and other electrical infrastructure. It is typically made of high-strength steel and consists of a large screw-like helix that is driven into the ground using hydraulic equipment.
The anchor is attached to the tower or structure via a steel cable or rod that is threaded through a loop on the top of the anchor. Once the anchor is installed and attached to the tower, it provides a reliable and long-lasting foundation that can withstand even the strongest winds and ground movement.
Power transmission earth anchors are commonly used in areas with soft or unstable soil conditions such as marshes, swamps, and areas prone to flooding. They are also used in areas with high wind loads such as coastal regions and mountainous areas.
