The main body of the screw 5 is arranged in the through groove 4, and preferably, the center line of the screw 5 coincides with the center line of the through groove 4. The two ends of the screw 5 are rotatably connected to the support beam 3. The movable base 6 is connected to the screw rod 5 by a threaded transmission. When the screw rod 5 rotates, the movable base 6 can be driven to move along the axis of the screw rod 5, that is, the movable base 6 can move along the length direction of the through slot 4. Any movable base 6 includes two support blocks, which are respectively a first support block 7 and a second support block 8. The first support block 7 and the second support block 8 are arranged opposite to each other. A tower accommodating area is formed in the area opposite to the first support block 7 and the second support block 8. The tower tube segment 12 can be accommodated in the tower accommodating area. A slide groove 9 is provided on the movable base 6. The first support block 7 and the second support block 8 are slidably connected to the slide groove 9. Preferably, the first support block 7 and the second support block 8 are slidably connected to the slide groove 9 through a slider 10. When the first support block 7 or the second support block 8 is moved into place, the slider 10 is fixed to the movable base 6 by bolts, etc., so as to limit the first support block 7 and the second support block 8.

Level the center frame 1 and the support beam 3 so that the working surfaces of the center frame 1 and the support beam 3 are on the same horizontal plane; the height difference between the center frame 1 and the support beam 3 should be controlled within 1mm. During the leveling, the jack can be used to assist the leveling, and the jack can support the center frame 1 and the support beam 3. After the leveling is completed, the center frame 1 and the support beam 3 are fastened with bolts, and the jack is unloaded and withdrawn.

According to the design process requirements, the vertical surface of the segment of the installed tower segment 12 is selected to be coated with epoxy resin glue or affixed with nitrile cork rubber pads.

[0035] S6. Repeat steps S3, S4 and S5 on the remaining support beams 3, and set the remaining tower segments 12 on the support beams 3. The distance between adjacent tower segments 12 is no more than 30 mm. Use bolts to fasten adjacent tower segments 12. Preferably, use arc bolts, pass through the reserved holes on the two tower segments 12, and connect nuts. At this time, do not set the torque of the arc bolts to the design value. At the same time, before using the arc bolts, the arc bolt threads and nuts should be coated with molybdenum disulfide.

[0036] S7. After the segments are ringed, the inner and outer diameters shall be inspected by using a steel tape measure to measure in four directions at intervals of approximately 45° on the same horizontal measurement section;

[0037] S8. Use a leveling instrument to measure the horizontality of the concrete tower;

After the tube segment is ringed and the measured data meets the design requirements, all bolts are torqued. According to the design value, it is hit twice, 50% for the first time and 100% for the second time; after completion, the anti-loosening line is drawn. Before torqueing, the position angle of the inclined gasket should be adjusted to make it fit the concrete surface and minimize the gap between it and the nut and the hexagonal head of the arc bolt.
