Problems solved by technology

The inventor found that the application of the spiral anchor foundation to the stay wire foundation also has significant disadvantages, and the tension relaxation of the stay wire is serious
The main reason for this phenomenon is that the overall rigidity of the spiral anchor foundation is low, the ability to resist horizontal force is weak, and the cable foundation is prone to horizontal displacement.

Embodiment 2

[0047] This embodiment discloses a method for fixing the stay wire of the stay wire tower. One end of the stay wire is fixedly connected to the pole of the stay wire tower, and the other end is fixed by using the basic structure described in the embodiment, which includes the following specific steps:

[0048] Step 1: Use an excavator or manually excavate the foundation pit, and excavate to the bottom elevation of the first foundation part.

[0049] Step 2: Use construction machinery to screw the screw anchor to the set depth on the bottom of the foundation pit. The set depth can be determined by pre-calculation. The construction machine can use the existing construction machinery for the screw anchor, and will not be described in detail here.

[0050] Step 3: Clean up the gravel at the bottom and sides of the foundation pit, ensure that the construction surface is flat, bind the reinforcement cages of the first foundation part and the second foundation part, and weld the steel...

Abstract

The invention relates to an infrastructure for a guy wire of a guyed tower, and a guy wire fixing method. The infrastructure for the guy wire of the guyed tower comprises a first foundation part buried beneath the ground, wherein at least one screw anchor is buried into the bottom part of the first foundation part; a second foundation part is arranged on the top surface of the first foundation part; the horizontal cross-section area of the second foundation part is smaller than the top surface area of the first foundation part; and the top surface of the second foundation part is used for stretching out to be above the ground and is connected with the end part of the guy wire. The infrastructure provided by the invention can effectively bear a tensile force of the guy wire so as to preventthe tensile force of the guy wire from relaxing.

Description

technical field [0001] The invention relates to the technical field of transmission line tower foundations, in particular to a foundation structure for guy wires of a guy tower and a guy wire fixing method. Background technique [0002] Compared with the self-supporting pole tower, the force of the cable tower is more reasonable, the tower weight can be reduced by about 30%, the amount of foundation concrete can be reduced by about 40%, the amount of foundation steel can be reduced by about 25%, and the overall cost of the line is significantly reduced. , The guyed towers have been widely used, and the inventors have found that the guyed towers also have significant disadvantages, the guyed wire tension is not easy to be guaranteed, and the line operation and maintenance work is heavy. [0003] Spiral anchor foundations have been widely used in guyed foundations, and this type of foundation can significantly reduce the amount of earthwork excavation, construction difficulty ...
