桥梁单元式多向变位梳形板伸缩缝施工技术

The construction technology of unit type comb plate bridge expansion joint for multi-direction-displacement

介绍了单元式多向变位伸缩缝的适用条件和特点,以京张高速公路桥梁伸缩缝型钢变形病害处置过程为例,介绍了单元式多向变位伸缩缝的施工工艺,并对单元式多向变位梳形板伸缩缝和传统的模数式伸缩缝进行了对比。

This paper introduces the applicable conditions and characteristics of unit type comb plate bridge expansion joint for multi - direction - displacement. Taking the deformation disease disposal process of Jing Zhang highway steel bridge expansion joints as an example, introduces the construction technology of unit type comb plate bridge expansion joint for multi - direction - displacement, and compares it with traditional modulus type expansion joint.
