COMPLEX CONSTRUCTION TECHNOLOGIES FOR BEIJING ZHONGGUANCUN SCIENCE, TECHNOLOGY AND TRADE CENTER PROJECT

Beijing Zhongguancun Science, Technology and Trade Center is a big landmark building in the district with floor area of 195800 m2. In the construction, measures were taken against technical difficulties and some new technologies developed and applied, such as the combined pit dewatering technology of percolating in assistance of pumping, integral pit support technology of big bored pile in combination with 3 anchoring pile and soil-nailing wall, application of GPS satellite locating technology to monitor the horizontal displacement of the foundation pit, 6.3 m supper-high unilateral underground formwork technology, 117 m super-long underground adhesive pre-stretching technology and XYPEX rigid waterproofing technology in structures under-&-aboveground as well as new formwork, reinforcement and concrete and etc. Intellectual informatization, environment protecting and energy-saving technologies were applied in the electro-mechanical works and decoration works. All of these have achieved good technical and economical effects.
