Embodiment Construction

[0028] An embodiment of the tower pile foundation outcrop raised structure, such as figure 1 , figure 2 with image 3 As shown, four pile foundation columns 100 , support trusses 200 and four outcropping columns 300 are included.

[0029] The supporting truss 200 includes a supporting column 220, a first cross bar 230, a first slanting bar 240, a first connecting bar 250, a second slanting bar 260, and a second connecting bar 270. The supporting column 220 and the pile foundation The columns 100 are matched one by one, the upper end is connected with the tower, and the lower end is connected with the pile foundation column 100 . The first cross bar 230 is perpendicular to the support column 220 , and its two ends are respectively connected to the upper ends of two adjacent support columns 220 . One end of the first diagonal bar 240 is connected to the lower end of any one of the support columns 220 , and the other end is connected to the middle of the first cross bar 230 c...

Abstract

The invention discloses a tower pile foundation exposure lifting structure and a construction method. The tower pile foundation exposure lifting structure comprises pile foundation columns, a supporting truss and exposure columns. The supporting truss comprises a plurality of supporting columns, first transverse rods, first slant rods, first connecting rods, second slant rods and second connecting rods, the supporting columns are matched with the pile foundation columns one by one, the upper ends of the supporting columns are connected with a tower, and the lower ends of the supporting columns are connected with the pile foundation columns. Each exposure column warps the corresponding supporting column and partially wraps the pile foundation column matched with the corresponding supporting column, the upper ends of the exposure columns are flush with the upper ends of the supporting columns, and the lower ends of the exposure columns extend to the pile foundation columns. The tower pile foundation exposure lifting construction method includes the steps of enabling the tower to be separated from the pile foundation columns, enabling the lower ends of the supporting columns of the supporting truss to be fixed on the pile foundation columns, enabling the upper ends of the supporting columns of the supporting truss to be fixed on the tower, and constructing the exposure columns outside the supporting columns and the pile foundation columns. According to the tower pile foundation exposure lifting structure and the construction method, the internal combination is compact, the structure is firm, tower pile foundation exposure can be effectively lifted, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the field of pole towers, in particular to a pole tower pile foundation outcrop raising structure and a construction method. Background technique [0002] As a support for supporting transmission lines in overhead transmission lines, pole towers are widely used in laying transmission lines. [0003] Towers are often erected in the wild, such as fields and forests. Due to the relatively large disturbance in these areas, the soil on the surface flows under the wind and rain, causing the outcropping of the pile foundation and even the tower body to be buried in the soil, resulting in the collapse of the tower. The height of the call is reduced, does not meet the initial design, and is prone to safety accidents. Contents of the invention [0004] Based on this, it is necessary to provide an elevated structure and construction method for the outcrop of the tower pile foundation to solve the problem that the outcrop of the tower p...
