Combined with the roof of Wuhan gymnasium,a new kind of structure system of suspend-dome,this paper probes into another kind of cast-steel joint: cast-steel clamp joint,which is expected to offer consults to the projects.

By the aid of temporary clamps and temporary hangers, the problem of positioning and fixing the group bolts in the central bands in a state of floating is resolved.

The technology, method and key points in erection of main cable, clamp and suspension cable are introduced.

In this paper,the structural characteristics of the main cable system of the three-tower suspension bridge are analyzed and several applied technical issues in relation to the fabrication and installation process of the main cables,hangers,cable saddles and cable clamps of the bridge are studied as well.

The computation and examination method of the main cable length,methods of computing and setting out the location of the cable clamps when the suspension bridge is under the condition of non load and dead load are introduced in this paper.

In this paper,the construction techniques for installation and system transformation of the suspension structure(cable clamps and hangers) of the bridge are mainly presented.

This paper briefly introduced the running experience of the OptiFormer of PM5 in Nanping paper mill, and particularly discussed the dewatering process and the configuration of the typical gap former.
