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 present invention relates to a foundation structure and a fixing method for stay wires of a stay wire tower, comprising a first base part for embedding below the ground, at least one helical anchor embedded in the bottom of the first base part, and a base part of the first base part The top surface is provided with a second base part, the horizontal cross-sectional area of ​​the second base part is smaller than the top surface area of ​​the first base part, the top surface of the second base part is used to protrude above the ground, and is connected with the end of the stay wire , the basic structure of the present invention can effectively bear the pulling force of the stay wire, and avoid the tension relaxation of the stay wire.

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 ...
