Slope terrain pier deformation repairing structure and repairing method

Abstract

The invention discloses a slope terrain pier deformation repairing structure and a repairing method. The structure comprises a support beam, a support key and two resistance piles. The two resistancepiles are arranged in slope foundations on two longitudinal sides of a bridge bearing platform correspondingly. The resistance piles and the two longitudinal sides of the bridge bearing platform are arranged at intervals, the resistance piles are located on the lower side of the slope foundation relative to the bridge bearing platform, the supporting beam is connected with the tops of the resistance piles, the supporting key is arranged between the supporting beam and the bridge bearing platform, one side of the supporting key is fixedly connected with the supporting beam, and the other side of the supporting key is fixedly connected with the bridge bearing platform. The resistance piles for providing a transverse supporting force are arranged on two longitudinal sides of a pier; and during construction, transverse deformation of an existing pier cannot be affected or is slightly affected, uncontrollable transverse deformation is avoided, the supporting beam provides a supporting foundation on one side and transmits a supporting force to the resistance piles, the supporting key can transmit the transverse supporting force to the bridge bearing platform, a high supporting and deformation resisting capacity is achieved, and a pier deformation repairing effect is improved.

Description

technical field [0001] The invention relates to the field of geotechnical engineering, in particular to a deformation repairing structure and repairing method of bridge piers on slope terrain. Background technique [0002] In hills and mountainous areas, slope topography is the main landform. The foundation rock and soil layer of slope topography is distributed in an inclined manner. The stability of foundation surface soil on the inclined bedrock surface will be affected by man-made and natural environmental changes, showing stability. When the terrain slope increases or the foundation is a landslide or rock pile, the tendency and degree of foundation stability degradation cannot be ignored. [0003] When a bridge project passes through such a slope terrain, since the bridge project mainly considers vertical load, its ability to resist horizontal load is weak, so in engineering practice, a large number of horizontal (lateral) deformation of the bridge exceeds the limit or e...

Problems solved by technology

[0003] When a bridge project passes through such a slope terrain, since the bridge project mainly considers vertical load, its ability to resist horizontal load is weak, so in engineering practice, a large number of horizontal (lateral) deformation of the bridge exceeds the limit or even fails. Case, it is very difficult to repair the horizontal deformation of the bridge on the slope terrain, and there is no good repair technology and method at present, so it is of great significance to propose a repair structure and repair method for the deformation of the bridge pier on the slope terrain, and it should also have the effect of deformation repair Good, convenient construction, good economy, environmental protection and favorable promotion, etc.
