Problems solved by technology
[0006] (1) The built overhead power transmission tower is located within the scope of the backfill earthwork. The tower foundation and some tower materials are buried in the earthwork, which cannot effectively protect the tower materials from corrosion and cannot make the tower body and foundation bear reasonable force.
[0007] (2) The self-heavyness of large-volume concrete, the bearing capacity of the foundation cannot meet the requirements, causing uneven settlement of the foundation, tilting of the tower, and cannot be used normally
However, the built towers are located in the flat area, which restricts urban development and the land cannot be used effectively

Embodiment
[0047] The novel iron tower foundation reinforcement and protection method provided by the embodiment of the present invention includes:
[0048] First build four new foundations, then chisel the top surface of the original iron tower foundation, bind the wall reinforcement, support the wall template, pour the wall concrete, the vibrator cannot directly touch the tower material, and the strength of the concrete can reach more than 70%. Remove the formwork; the construction should choose the concrete mix ratio reasonably, choose cement with low heat of hydration, add appropriate fly ash and admixture, control the amount of cement, and make maintenance and temperature measurement. The difference between the internal temperature of the concrete and the surface temperature, and the difference between the external surface of the concrete and the ambient temperature shall not exceed 25°. The main reinforcement of the pile in the contact part of the pile and the ring beam is anchored...

The invention belongs to the technical field of iron tower foundation reinforcement and protection, and discloses a novel iron tower foundation reinforcement and protection method. A reinforced concrete protective wall is used to wrap the tower body, and together with the iron tower tower materials, a steel concrete shear wall cylinder combination with steel diagonal braces is formed. The structure can effectively resist external loads. The tower material is located in the middle of the wall. The partition of the tower body is wrapped with a reinforced concrete partition protection board. There are multiple permeable holes in the middle of the board. Four new pile foundations (or digging foundations, steps) are newly implemented at the bottom of the tower. Type foundation) together with the original tower foundation bears the load of the tower body and the reinforced concrete protective wall; the ground under the tower is cleared and planted, paved with gravel soil, piled with bagged soil around the tower body, and evenly backfilled with compacted muck. The invention forms permanent protection for the tower material; the force is reasonable and does not affect the use function of the iron tower.
Description
technical field [0001] The invention belongs to the technical field of iron tower foundation reinforcement and protection, and in particular relates to a novel iron tower foundation reinforcement and protection method. Background technique [0002] At present, the closest existing technology: the tower body is brushed with anti-rust paint to backfill the soil body, and the tower body is buried with plain concrete. [0003] The tower body is buried in the backfill soil, and the tower body is painted with anti-rust paint. The tower material is eroded by groundwater for a long time. The service life of the anti-rust paint is limited, and it cannot form permanent protection for the tower material. [0004] The plain concrete body buries the tower body, forming a permanent protection for the tower material, but the large-volume concrete is heavy, which is easy to cause foundation settlement, tower tilting, and accidents. [0005] In summary, the problems in the prior art are: ...
