[0029] Such as Figure 1-Figure 3 As shown, the step dislocation construction method of the bridge with high pier in mountainous area in the present embodiment comprises the following steps:
[0030] Step 1: The hanging basket truss walks to the N section, and the template is installed to bind the bottom plate reinforcement of the N section and the roof reinforcement of the N-1 section;
[0031] Step 2: Concrete is poured for the N-segment bottom plate and the N-1 segment roof slab, and at the same time, the N+1 segment folded web is installed and constructed by self-hoisting the folded web with a hanging basket;
[0032] Step 3: The hanging basket truss travels to the N+1 segment, tensions the prestressed roof plate of the N-1 segment, and reciprocates in sequence for the cycle of the next segment.
[0033] The construction method in the present invention expands one operation area to three operation areas, and the three segments are constructed independently and synchronous...
