This paper introduces two kinds of assembling and lifting methods(the integrated vertical lifting method and the sliding method) used in the ball-grid installation,and puts forward some problems existing in the construction.

The paper describes the key technology of vertical lifting belt conveyor with corrugated baffle.

It will be convenient to popularize and apply the advanced technology of pipe transportation system for cooked cocoon if vertical lifting is used into it.

Combining the practical vertical lifting, they also introduce some equipment and construction methods such as lifting equipment, lifting platform, command and control, safety and fall\|prevention measures and so on.

Research of vertical hoist belt conveyor;

The technology characteristic and dynamic and type select and construct composition of an vertical hoist continuous convey system,by way of research of the key technology and the result of analogy bench run, show the feasible of technology used in the engineering of subway build,it should be giving full play of the tunneling shield and greatly raise the advance speed.

Based on structures characteristics,roof cable-net structure was installed by integral lifting method,and the installation scheme was introduced in this paper.

This paper has presented the construction technique of the assembling in site about the large-span steel pipe roof truss and the technique of integral lifting about the truss.

The integral lifting of steel truss in the National Conference Center Project has finished the technical problems that needed to be resolved in four times of steel truss lifting according to the project characteristics and difficulties.
