Problems solved by technology

The following problems will be involved: ① The foundation bearing capacity of the bearing layer of the foundation of the transmission tower is low, and the shallow covering soil layer is thick, which requires a larger area and deeper foundation burial depth, and the excavation volume of earth and stone is large. The amount of steel is also large
② The foundation covers a large area and is greatly affected by external interference
③The maintenance period is long and the construction is cumbersome, which cannot meet the engineering application requirements for emergency repairs
④Large material consumption and great impact on the environment

Embodiment 1

[0055] Such as figure 1 and Figure 4 As shown, a composite foundation for a power transmission tower, the power transmission tower includes a vertically arranged tower body and a tower window 1 on the upper end of the tower body; the composite foundation includes a load-bearing platform 2 and a 2. The spiral anchor rod 3 at the lower end is characterized in that,

[0056] The bearing platform 2 is provided with a vertical steel bar 4;

[0057] The spiral anchor rod 3 is vertically arranged around the vertical steel bar 4 , and its upper end is provided with a connection assembly connected with the load-bearing platform 2 .

[0058] The shape of the tower window 1 is polygonal, which includes horizontally arranged cross arms 5, support arms 6 arranged symmetrically on both sides of the tower body perpendicular to the cross arms 5, and arranged between the support arms 6, A beam 7 arranged along the radial direction of the tower body;

[0059] The crossbeam 7 divides the to...

Abstract

The invention relates to a compound foundation for a power transmission tower. The power transmission tower comprises a tower body vertically arranged, and a tower window arranged at the upper end of the tower body; the compound foundation comprises a bearing table and spiral anchor rods arranged at the lower end of the bearing table; the bearing table is provided with a vertical reinforcement; and the spiral anchor rods are vertically arranged around the vertical reinforcement, and are provided with connecting components, connected with the bearing table, at the upper ends. The compound foundation, provided by the invention, is high in foundation bearing capacity, low in installation and maintenance difficulty and low in construction and maintenance costs.

Description

technical field [0001] The invention relates to power transmission equipment, in particular to a composite foundation for power transmission towers. Background technique [0002] The tower foundation of the transmission tower The tower foundation buried in the ground provides load support for the transmission line tower, and is an important part of the transmission line structure system. In the construction of the power grid, the height of the tower reaches tens of meters. The existing tower foundation cannot guarantee the stability requirements of the transmission tower, and it will tilt and even cause human and economic losses. Therefore, it is necessary to provide a tower foundation to ensure the stability of the transmission tower. [0003] The existing pole tower foundation adopts the fixing method of fixing the supporting foot of the iron tower in the foundation pit after digging a pit on the ground, and then embedding natural soil in the supporting foot and then comp...
