Problems solved by technology

At present, the overall tower displacement construction method is to dismantle the 36-meter-high large iron tower. Because it is located on the edge of the river, the construction site is limited and the construction progress is slow. It is moved to an appropriate position and assembled. This method is cumbersome and complicated. It is very difficult, there are many links in dismantling and assembling the iron tower, there are many risk factors, and a large amount of tools are used during construction. At the same time, two 25-ton cranes and 60 operators are required. It takes 2.5-3 days to dismantle and reassemble the iron tower. It also takes 2-3 days, and the power outage will take a long time. If you encounter bad weather or thunderstorms, the construction period will need to be extended

Embodiment Construction

[0019] As shown in the figure, the overall iron tower displacement construction method involved in the present invention comprises the following steps:

[0020] 1) The staff ascend the tower to remove the guide and ground wire accessories on the tower, put the guide and ground wire into the wire pulley, and after the pulley door is sealed, use 4 balanced stay wires, one end of which is fixed on the lower plane of the cross arm , the other end is connected to the ground anchors on both sides of the new tower position and the original tower position on the ground. The staff on the tower conduct a comprehensive inspection, and deal with any problems in time. After there is no problem, the staff on the tower evacuate to the ground. Set up a holding pole on both sides between the front of the new tower position and the original tower position, and drop the wires on both sides of the tower on the top of the holding rod to support the wires;

[0021] 2) The ground between the new tow...

Abstract

The invention provides a construction method for overall iron tower displacement. The construction method is simple in construction, safe in operation. Since the iron tower is moved as a whole, the construction method can shorten the construction time and power failure time, can reduce time and labor and lower the expense of the construction. The construction method for the overall iron tower displacement comprises the following steps: 1. a working personnel climbs the iron tower, dismantles guide wire accessories and ground wire accessories and place the guide wire accessories and ground wire accessories into a conducting wire pulley; four roots of balance stay wires are adopted to fix the iron tower; 2. the ground between a new position of the iron tower and an original position of the iron tower is repaired, leveled and tamped, so as to form a displacement channel; sleepers are cushioned; steel tracks are paved on the sleepers; reinforcing crossbeams are adopted to reinforce the four tower corners of the iron tower; four lifting jacks are adopted to prop up the reinforcing crossbeams; 3. screws on the foot of the iron tower are dismantled; the lifting jacks are adopted to support the iron tower; tower foot plates are mounted on the tower feet, fall into the steel tracks and are dragged by a tractor; 4. the tower foot plates are dragged to the new position of the iron tower and jack up the iron tower over again; the tower foot plates are dismounted; the steel tracks and the sleepers are removed, so as to enable the iron tower to be situated in the new position of the iron tower; foundation bolts are fastened; the guide wire accessories and ground wire accessories are well mounted.

Description

technical field [0001] The invention relates to a displacement construction method of an integral iron tower. Background technique [0002] In the power system, for the iron tower near the Hetao, the tower foundation is easy to be exposed after several years of operation due to the river water scouring the tower foundation. Therefore, the tower must be moved to the power transmission side for a certain distance (about 10 meters). At present, the overall tower displacement construction method is to dismantle the 36-meter-high large iron tower. Because it is located on the edge of the river, the construction site is limited and the construction progress is slow. It is moved to an appropriate position and assembled. This method is cumbersome and complicated. It is very difficult, there are many links in dismantling and assembling the iron tower, there are many risk factors, and a large amount of tools are used during construction. At the same time, two 25-ton cranes and 60 oper...
