METHOD OF CONSTRUCTING RIBBON BRIDGE WITH MULTI-STEP TENSIONING ON GROUND ANCHORS

摘要

The present invention relates to a kind of building stressed ribbon bridges. This method building stressed ribbon bridge includes: that two bridges of the interim installation concrete block closed position of step are separated from each other; The first fixing step concrete block tensed uses mobile home pool to stay on the ground, and tensioning mobile home pool is stayed first; It is a kind of support cable unit step installation two or more rows support cable connection concrete block be separated from each other; One section of installation steps installation building section is to support floorboard section to support cable in the first stretching step; And second stretching step second step tensioning mobile home pool reside in floor section installation steps. A kind of soil pressure acts on soil adjustment within the allowable range, it is environmental-friendly in can be to minimize the pulling force mobile home born using concrete pool without the both ends installation stressed ribbon bridge of abutment after construction base concrete, and lower structure is provided, it is simply constructed. ;The 2016 of copyright KIPO submissions
