Description

Reinforcement construction method of transmission steel tower

The present invention relates to a method for reinforcing the main body of a transmission tower, and more particularly, it is provided on the lower side of a transmission tower supporting a transmission line that supplies power produced in a power plant to each region through a substation for power supply. The present invention relates to a method for reinforcing the main body of a transmission tower, which firmly supports the transmission tower by firmly reinforcing the main body of the transmission tower buried in the ground.

In general, the process of transporting electricity produced by a power plant to a distant factory or general home is called transmission, and a tower facility with a truss structure that supports the transmission line used for transmission is called a transmission tower.

In addition, since the transmission line through which high-voltage current flows is very thick and heavy, the transmission tower must be constructed safely by making a sturdy tower using steel. It is configured to have a leg.

Since these transmission towers are usually constructed at a height of 80 to 105 feet, they are manufactured to have adequate lateral strength to withstand bending and excessive shaking caused by the weight and wind of the transmission line, but strong winds, external shocks, or earthquakes Problems in structural strength, which can be easily collapsed by natural disasters such as these, are constantly being presented.

Accordingly, in order to reinforce the transmission tower, a concrete reinforcement body is separately constructed so that the transmission tower main body provided in the lower part of the transmission tower is connected to enable strong support for the transmission tower. In this case, after excavating the surrounding ground of the transmission tower at the site, assembling formwork and reinforcing bars, and then pouring concrete to construct the concrete reinforcement body, there is a problem in that the construction period is prolonged and the construction cost is increased accordingly.

In order to solve this problem, various technologies for reinforcing the transmission tower without pouring concrete have been devised.

As an example of the prior art, the reinforcing frame structure of the high-voltage electric pylon base, which is No. 20-0419865 for the registration room, has been devised, which is a reinforcing frame for reinforcing the base of the high-voltage electric pylon in the high-voltage electric pylon supported by the foundation concrete. The reinforcing frame is a rectangular upper fastening frame that is in close contact with the lower circumferential surface of the rectangular high-voltage electric pylon, and the upper end is coupled to the inner surface of the corner of the upper fastening frame, and the lower end is a rectangular lower fastening frame The upper end is coupled to the lower surface of the rectangular lower fastening frame, and the upper end is coupled to the lower surface of the rectangular lower fastening frame, and the upper end is coupled to the upper surface of the cross bar cross-coupled to the high-voltage electric tower and formed to be coupled to the outer leg part of the high-voltage electric tower and a plurality of fastening members. It consists of a plurality of foundation reinforcing piles respectively embedded in the soft ground foundation in a pointed shape, and a connecting member connecting the vertices of the rectangular upper fastening frame and the lower fastening frame.

In this prior art, the outer leg of the high-voltage electricity pylon is firmly coupled with a plurality of fastening members with a girder-type fastening junction beam, and a plurality of foundation reinforcing piles are driven and fixed in the soft ground, thereby subsidence in the soft ground where the high-voltage electric pylon is installed. making sure it doesn't happen.

As another example, Patent Registration No. 10-1910436, a pylon stabilization device for an extra-high voltage transmission line, has been devised, which includes an installation groove formed at a certain depth in the center between concrete blocks embedded in the ground to fix the lower post of the pylon, and the installation An installation box embedded in the groove, an operation motor embedded in the installation box, a ball screw rotating by receiving the power of the operation motor, and the ball screw are toothed and elevate or descend in the installation groove according to the operation of the operation motor Extra high pressure including a pull roll block and a plurality of pull rolls built into the pull roll block, one end fixed to the lower strut, the other end wound around the traction roll, and then drawn out again and bound to the other lower strut. In the pylon stabilization device of a power transmission line, the open upper surface of the installation box is screwed and closed with a box cover, and a plurality of wire through holes are formed in the box cover to allow a traction wire to pass through, and the center of the four inner sides of the installation box A sliding guide groove is formed in the center of the pull roll block, and a screw fastening hole is formed through the center of the pull roll block to engage the ball screw, and a guide block fitted into the sliding guide groove protrudes from the center of the lower four sides of the pull roll block. The inside of the pull roll block has a predetermined depth of roll installation grooves of a certain radius on four sides, and the shaft is fixed in a form in which the pull roll is embedded. It is fixed and the other end is rotatably shaft-fixed on an installation groove cover that seals the opening of the roll installation groove, and wire traction grooves are formed in a spiral shape on the outer circumferential surface of the traction roll by 2-3 pitches, and on the upper surface of the traction roll block, respectively A wire guide hole is formed to communicate with the roll installation groove.

This prior art enables a safe extra-high voltage transmission line to be maintained in response to a change in the tension of the transmission line while being safely maintained even by strong winds.

However, in the case of the former, these prior technologies are made to connect the reinforcement frame with the lower structure of the transmission tower rather than the lower transmission tower main body of the transmission tower buried in the ground. There is a problem that it is not done at all.

In addition, although the lower part of the reinforcing frame is buried in the ground, in order to bury the lower part of the reinforcing frame in the ground, the workability is deteriorated as the lower part of the reinforcing frame must be buried after digging up the ground by extending from the lower periphery of the transmission tower. Accordingly, there is a problem in that the construction time is delayed as well as the construction cost is increased.

Also, in the latter case, as it is made to be connected to the installation box by a wire and the substructure of the transmission tower, not the main body of the lower transmission tower of the transmission tower buried in the ground, reinforcement for the main body of the transmission tower that substantially supports the tower There is a problem that it is not done at all.
