At S4, connecting one end of all the outer radial cables 3 through the connecting ring of the ring beam structure 4 to a lifting mechanism, lifting the inner radial cables 2 and the ring cable structure 1 to a preset position by the outer radial cables 3, and then connecting the outer radial cables 3 to the ring beam structure 4, where the preset position refers to a position where the outer radial cables 3, the inner radial cables 2 and the ring cable structure 2 are load balanced, and at this time, the length ratio of the outer radial cables 3 to the inner radial cables 2 is between 1: 4 to 1: 7, in particular, the ratio of the lengths of the outer radial cords 3 and the inner radial cords 2 may be 1: 4. 1.3: 6. 1.4: 6. 1.3: 6.1, 1.4: 6.1 or 1: 7. the lifting mechanism may be a crane, a crane or a hydraulic jack.
The arrangement has the advantages that by connecting the inner radial cables 2 with the annular cable structure 1 and connecting the outer radial cables 3 with the inner radial cables 2, the difficulty in alignment when the outer radial cables 3 are connected with the annular beam structure 4 in the air is avoided; the inner radial cables 2, the outer radial cables 3 and the looped cable structure 1 are integrally lifted by lifting the outer radial cables 3 to a preset position, so that the construction steps are simplified, and the construction efficiency is improved; on the other hand, the construction of a large number of temporary towers is avoided, and the safety risk caused by later-stage disassembly of the temporary towers is reduced; the pulling of the ring-shaped rope structure 1 by the ring-shaped beam structure 4 is realized by connecting the outer radial ropes 3 with the ring-shaped beam structure 4.
In step S1, the laying of the ring cable structure 1 in the area surrounded by the ring beam structure 4 includes: laying the lower annular cable structure 12 in the area surrounded by the annular beam structure 4; lifting the upper ring structure 11; the support structure 13 is connected to the upper and lower ring cable structures 11 and 12, respectively.
In step S1, the step of laying the lower ring cable structure 12 in the area surrounded by the ring beam structure 4 includes: placing the lower looped cable structure 12 on the temporary platform; before the upper ring cable structure 11 is lifted, a temporary support is built on the temporary platform and comprises a base plate and a support, the base plate is located on the upper side of the support, one end of the support is in fastening connection with a base plate bolt, the other end of the support is in fastening connection with a temporary platform bolt, and the upper ring cable structure 11 is placed on the base plate.
Thus, the temporary support is built before the upper ring cable structure 11 is lifted, and the upper ring cable structure 11 is laid on the temporary support, so that the temporary support can separate the upper ring cable structure 11 from the lower ring cable structure 12 to avoid the lower ring cable structure 12 from interfering with the lifting of the upper ring cable structure 11; on the other hand, when the upper ring cable structure 11 accidentally drops in the lifting process, the temporary support can catch the lower ring cable structure 12, so as to prevent the lower ring cable structure 12 from dropping and injuring workers.
In step S1, lifting the upper ring structure 11 includes: one end of the temporary guy cable is connected with the upper guy cable structure 11, the other end of the temporary guy cable passes through the connecting ring of the ring beam structure 4 to be connected with the lifting mechanism, and the lifting mechanism lifts the upper guy cable structure 11 through the temporary guy cable, so that the vertical distance between the upper guy cable structure 11 and the lower guy cable structure 12 corresponds to the length of the supporting structure 13.
Therefore, one end of the temporary guy cable is connected with the upper guy cable structure 11, and the other end of the temporary guy cable passes through the connecting ring on the ring beam structure 4 to be connected with the lifting mechanism, so that the lifting mechanism can lift the upper guy cable structure 11 through the temporary guy cable, the lifting of the inner radial cable 2 is avoided, and the tension damage caused in the lifting process of the inner radial cable 2 is eliminated; on the other hand, the temporary inhaul cable can be integrally lifted by the lifting mechanism to form the ring cable structure 1, so that a large number of scaffolds are prevented from being erected, and the construction cost and the safety risk caused by dismantling the scaffold cable are reduced.

On the other hand, after the supporting structure 13 is connected with the upper ring cable structure 11 and the lower ring cable structure 12, the ring cable structure 1 is directly formed, so that the situation that the position adjustment needs to be carried out on the ring cable structure 1 after the supporting structure 13 is installed is avoided, the installation steps of the ring cable structure 1 are simplified, and the construction efficiency of the ring cable structure 1 is improved.

One end of a stay is connected with the looped cable structure 1, and the other end of the stay is connected with the lifting mechanism, and the lifting mechanism lifts the looped cable structure 1 through the stay so as to enable the inner lower radial cable 22 to leave the ground. Thus, before the support column 23 is connected to the inner upper radial cables 21 and the inner lower radial cables 22, respectively, the looped cable structure 1 is lifted to make the inner lower radial cables 22 leave the ground, so that a certain gap is formed between the inner lower radial cables 22 and the ground, and the ground is prevented from interfering with the installation of the support column 23; on the other hand, the inner lower radial cables 22 can support the supporting columns 23, so that the supporting columns 23 can be connected with the inner upper radial cables 21 conveniently.

This has the advantage that, by first connecting the inner upper radial cables 21 to the upper ring cable structure 11 and connecting the inner lower radial cables 22 to the lower ring cable structure 12, so that a mounting area for the support column 23 is formed between the inner upper radial cables 21 and the inner lower radial cables 22, on the one hand, the mounting of the support column 23 can be facilitated; on the other hand, the supporting columns 23 can be installed in the vertical direction, so that the situation that the positions of the inner radial cables 2 need to be adjusted again when the inner radial cables 2 are connected with the looped cable structure 1 after being spliced is avoided, the installation steps of the inner radial cables 2 are simplified, and the construction efficiency of installing the inner radial cables 2 is improved.
