Construction method for arranging asymmetric support system in cross section direction of small-radius curve cast-in-place beam
The invention belongs to the technical field of a cast-in-place beam support system of a highway, aims to solve the problem that the same form of support systems cannot be adopted due to complicated geographical conditions in the cross section direction of a small-radius cast-in-place continuous beam of a highway, provides a construction method for arranging an asymmetric support system in the cross section direction of a small-radius curve cast-in-place beam, and particularly provides a construction method for arranging the asymmetric support system in the cross section direction of the small-radius curve cast-in-place beam under the complicated geological conditions. According to the construction method, the same cross section support foundation is treated through two steps: intact loess foundation on one side adopts 3:7 lime earth for backfill and C20 concrete for hardening earth's surface, the independent pile foundation on the opposite side adopts a pile foundation and support system, the asymmetric support system is adopted in the beam cross section direction during construction, the problem that the same form of the support system cannot be adopted due to the complicated geographical conditions in the cross section direction of the small-radius cast-in-place continuous beam of the highway is solved, and requirements for engineering safety, quality and progress are met.
