Abstract: | Introduced in this paper is the construction quality control for many types of bridge expansion & contraction joints in the northwest section of Shanghai Outer Ring Line. The interrelationship between bridge structure and expansion & contraction joints has been analyzed, the quality control points have been found out and practical technological process has been proposed. The inspection result shows the qualified ratio of all the 55 bridge unit projects and more than 300 expansion & contraction joints is 100%. After 3 years' operation, the expansion & contraction joints remain in good conditions. It has been elected the Shanghai Municipal Road Model Project. |
