The invention discloses a
bedding rock surface bridge steel
pipe support foundation and a treatment method thereof, and relates to the technical field of support foundation treatment methods. The
bedding rock surface bridge foundation treatment method comprises the steps of S1, work before hole forming, S2, anchor cable hole drilling, S3, anchor cable lowering, S4, tension reaction beam and anchortool mounting, S5, load application, S6, load holding, and S7, unloading. According to the
bedding rock surface bridge foundation treatment method, main ribs tops are subjected to pre-bending treatment before bearing platform steel reinforcing ribs are bound, the steel reinforcing rib anchorage capacity and bearing platform
punching-resisting capability can be improved, based on the anchor cableframe beam principle, a jack is used for exerting tension force to a steel strand, whether the micro
pile stress condition is consistent with calculation or not is verified, a seamless steel
pipe is adopted for following so as to carry out micro
pile hole drilling construction, it is ensured that a micro
pile does not incline on a bedding rock surface, the pile can be formed completely, and hole collapses do not exist, the good effect is achieved in the complex flysch stratum, the micro pile
adaptation of the flysch stratum is verified, and the method is simple, economical and convenient.
