And Control

The composite bailey beam and fastener-style steel pipe group support possesses the characteristic of low security risk and construction cost. But its vertical crossing scope of the working area is comparatively huge with many factors which would influence the construction. Therefore, it is required to organize the construction meticulously, improve the construction technology and clarify the construction control points.

The city fast track railway bridge studied in this paper is located above an old mined out area. There is a 1500m2 underground goaf in the construction site with a depth of 30.8~53.2m, the seam thickness is 2.0~2.5m and the dip angle is 50~63 degrees. Although the mine has been abandoned for many years, there are still a lot of underground cavities. Collapse pits occurred on the surface occasionally till this day, especially during the rainy season. In order to make the design safe and reliable, drilling pressure grouting technique is proposed to fill and reinforce the foundation of the site. Proposed technique is tested by several experiments in simulated underground mined out area for the foundation treatment. The technical design, construction technology, grouting and reinforcement effect of the project are studied and summarized. The results of the experiment showed a stable and safe bridge foundation has been achieved. The proposed technique was then applied to on site experiment and pasted all tests.

Fastener-style steel pipe formwork scaffolding system is a body made up of different components, such as plates, rods, blocks of space structure system,Force process of its being repeatedly affected by construction technology,and providing a comprehensive analysis of mechanical characteristics of each component in the system is relatively difficult.But only in the design and analysis of vertical rods as object design and analysis is not enough, vertical Rod itself is not a simple one-way rod of, it is in the system and the horizontal rod, floor stiffness, the upper cord and the ribs and other components affected.Therefore, from the overall awareness of fastener-style steel pipe formwork support system, a comprehensive analysis of connection characteristics, and interactions between the various components,thus summed up the practical computing model for each component in order to essentially recognize the bracket system, eliminate the source of accidents fundamentally.
