But for corner towers, the usual construction method is to determine the height difference on both sides of the inclined surface of the foundation and scrape it with a flat plate, but there are many anchor bolts standing on the top surface of the foundation, which cannot be scraped continuously
As a result, the top surface of the foundation is uneven, the joint between the flange and the foundation surface is poor, and the direction and angle of the tower's pre-deflection are inaccurate, which directly affects the force requirements of the tower body

The invention discloses a foundation top surface brushing method of a power transmission tower. The power transmission tower comprises a power transmission tower foundation, studs are arranged on thetop surface of the power transmission tower foundation, guide rails are built above the top surface of the power transmission tower foundation, all the guide rails are arranged in parallel, connectingsleeves are arranged on the guide rails, sleeve rail sleeves and connecting flat plates are arranged on the connecting sleeves, sleeve holes are formed in the sleeve rail sleeves, connecting holes are formed in the connecting flat plates, the connecting flat plates are connected with the studs through the connecting holes, and the sleeve rail sleeves sleeve the guide rails; and an operating rod capable of moving in the extending direction of the guide rails is arranged above the guide rails, a through hole is formed in the operating rod, a height adjusting shaft perpendicular to the operatingrod is arranged in the through hole, the upper end of the height adjusting shaft extends out of the upper side of the through hole, and a brush flat plate is arranged at the lower end of the height adjusting shaft. The guide rails are set to be a pre-deflection angle, and the operating rod moves along the guide rails, so that the structure can be used for well realizing the leveling of the pre-deflection angle of the top surface of the foundation of the power transmission tower. The method is used for building the power transmission tower.
Description
technical field [0001] The invention relates to the field of electric equipment, in particular to a method for leveling the top surface of a power transmission tower foundation. Background technique [0002] The high-voltage transmission towers of 110kV and above are divided into straight towers and corner towers. The straight line tower only supports the wires, while the corner tower stands at the corner and bears a large lateral tension. The corner tower is generally inclined to a certain pre-deflection angle in the opposite direction of the lateral tension of the conductor, and the tension of the conductor is balanced after erection to keep it vertical. Therefore, the top surface of the foundation of the straight tower is a horizontal plane, while the top surface of the foundation of the corner tower should be made into an inclined plane, and the slope is the pre-deflection angle of the tower. [0003] In the foundation construction of the horizontal plane, use a spirit...
