In above-mentioned work progress, since pylon is using vertical segmented assembly, need using to large-scale tower crane, difficulty of construction It is larger;And due to the installation of tower with suspended cable need to rely on two sides end bay steel lagging jack and in across steel lagging jack, it is necessary in end bay steel Arch rib can just carry out the assembly of tower with suspended cable in after the completion of across steel lagging jack construction, need after tower with suspended cable is installed, Can carry out the installation of next segment bridge, therefore, such mode installs tower with suspended cable, occupy the main structure construction duration compared with It is long, so that the bridge construction duration is longer, higher cost.

Summary of the invention

In view of the deficiencies in the prior art, the purpose of the present invention is to provide a kind of installation method of tower with suspended cable, Construction is simple, easy for installation, save the cost.

To achieve the above objectives, the technical solution adopted by the present invention is that:

A kind of installation method of tower with suspended cable, includes the following steps:

S1: it after the completion of the construction of end bay steel lagging jack, along vertical bridge to assembled tower with suspended cable section by section on end bay steel lagging jack, and installs In across steel lagging jack, and end bay steel lagging jack close in the position mounting seat across steel lagging jack, by tower with suspended cable one end and the bottom Seat is hinged;

S2: after the completion of tower with suspended cable is assembled, tower with suspended cable the other end install extend in across steel lagging jack before hang Rope and the rear hoist cable extended to end bay steel lagging jack, cable crane lifting tower with suspended cable simultaneously make tower with suspended cable turn to vertical state;

S3: the preceding hoist cable of tensioning and rear hoist cable, and preceding hoist cable is connect in across steel lagging jack, rear hoist cable and end bay steel lagging jack connect It connects, completes the installation of tower with suspended cable.

Based on the above technical solution, across steel lagging jack in being installed while assembled tower with suspended cable in step S1.

Based on the above technical solution, step S2 further include: tower with suspended cable two sides respectively install one for adjust hang The interim wind cable that Sarasota frame is spent vertically, interim wind cable are connected with jack, when tower with suspended cable is turned to close to vertical state, open Dynamic jack, and tower with suspended cable is turned to by vertical state by interim wind cable.

Based on the above technical solution, step S1 further include: bracket is set on end bay steel lagging jack, on bracket by Save assembled tower with suspended cable.

Based on the above technical solution, at the top of tower with suspended cable, end bay steel lagging jack and in across being respectively mounted on steel lagging jack Anchor case, preceding hoist cable both ends respectively with tower with suspended cable and in across steel lagging jack anchoring, rear hoist cable both ends respectively with tower with suspended cable and end bay Steel lagging jack anchoring.

Based on the above technical solution, two bottoms are horizontally mounted in the position across steel lagging jack in end bay steel lagging jack Seat, and the bottom end of the tower with suspended cable and two pedestals is hinged.

Compared with the prior art, the advantages of the present invention are as follows:

(1) in the present invention tower with suspended cable installation method, using along vertical bridge to by the way of segmented on end bay steel lagging jack Assembled tower with suspended cable can carry out assembly using common crawler crane or truck crane, without using large-scale tower crane, construction is simple, peace Dress is convenient, save the cost.

(2) in the installation method of tower with suspended cable of the present invention, while across steel lagging jack in an installation, the spelling of tower with suspended cable is carried out Dress, the assembled process of tower with suspended cable will not occupy the main structure construction time, shorten the bridge construction duration, reduce cost.

(3) first tower with suspended cable is turned to close to vertical state with cable crane in the present invention, reuses jack tension and faces When wind cable tower with suspended cable turned into vertical state, since jack control precision is high, can make tower with suspended cable gradually rotate to Vertical state improves the precision of tower with suspended cable vertical state.

Detailed description of the invention

Fig. 1 is the schematic diagram of the assembled process of tower with suspended cable in the embodiment of the present invention;

Fig. 2 is the scheme of installation of tower with suspended cable in the embodiment of the present invention.

In figure: 1- end bay steel lagging jack, 2- tower with suspended cable, 21- column, 22- lateral connection system, 3- pedestal, across steel arch in 4- Rib, hoist cable before 5-, hoist cable after 6-, the interim wind cable of 7-, 8- bracket, 9- anchor case.

Specific embodiment

Invention is further described in detail with reference to the accompanying drawings and embodiments.

Referring to figure 1 and figure 2, the embodiment of the invention provides a kind of installation methods of tower with suspended cable, including walk as follows It is rapid:

S1: after the completion of end bay steel lagging jack 1 is constructed, along vertical bridge to assembled tower with suspended cable 2 section by section on end bay steel lagging jack 1, and Across steel lagging jack 4 in installation, and the position mounting seat 3 across steel lagging jack 4 in end bay steel lagging jack 1 is close, by 2 one end of tower with suspended cable It is hinged with pedestal 3;
