Description

Correction device for power transmission tower

technical field

The utility model relates to the technical field of electric power, in particular to a deviation correcting device for a power transmission tower.

Background technique

As an important part of high-voltage transmission lines, transmission towers account for a large proportion of the total investment in high-voltage transmission lines. For some towers on soft ground, it may be due to their own poor geological conditions, or due to survey errors, improper design, poor construction quality, natural disasters, etc., or due to urban construction. The denser new buildings, the development of underground space, the excavation of deep foundation pits and other reasons, in the long-term operation process, uneven settlement of the foundation will occur, resulting in serious deflection of the tower. If measures are not taken in time, foundation settlement and tower deflection may further develop, which may eventually lead to damage to the stability of the tower foundation, major accidents such as inverted poles and disconnected wires, threatening the safety of local power supply and personal property Safety. Therefore, it is very important to give a reinforcement and rectification technology for deflected towers.

In order to solve the above problems, another tower position can be selected for line reconstruction, but the above method has the following problems:

1. It will affect the normal power supply of the power load related to the transmission line on the tower, especially not suitable for towers that have a greater negative impact on power outages such as industrial power load concentration and high voltage levels;

2. For towers with complex terrain, it is difficult to re-locate the site.

Utility model content

The purpose of the utility model is to provide a deflection correcting structure for a power transmission tower, which can overcome the deficiencies of the prior art, and correct and reinforce the power transmission tower without affecting the normal operation of the power system.

The utility model is achieved in that:

A deflection correction device for a power transmission tower, which includes: a frame beam, the frame beam connects two adjacent original foundations, fixed ribs are implanted at the connection between the frame beam and the original foundation, and the sinking original foundation A jacking device is set under the foundation.

In one of the embodiments, the frame beam is provided with a plurality of anchor rod static pressure pile holes, and is pressed with anchor rod static pressure holes.

In one of the embodiments, the anchor static pressure pile is a 250mm*250mm square pile.

In one of the embodiments, the frame beam is a planar frame beam.

The utility model connects the original foundation and the frame beam together, and reinforces it through the fixing ribs, and at the same time, transfers the load of the tower to the frame beam and the frame beam through the action of the anchor static pressure pile. The anchor static pressure pile is implemented, and the static pressure underpinning is implemented, and then the original foundation that sinks is jacked up by the jacking device.

Compared with the prior art, the correction structure of the transmission tower of the utility model has the following beneficial effects:

1. It will not affect the normal power supply with the power load of the oil pipe of the transmission line on the transmission tower, especially for the transmission tower with concentrated industrial power load and high voltage level;

2. No need to re-select the site, no need to replace or rebuild the transmission tower;

3. The construction time is short, and the price of engineering transformation is relatively economical and reasonable, which is suitable for large-scale promotion.
