Deformation repair structure and repair method of bridge pier on slope terrain

Abstract

The invention discloses a repairing structure and repairing method for the deformation of bridge pier in slope terrain, which comprises a support beam, a support key and two resistance piles. The vertical sides of the cap are arranged at intervals, and the resistance pile is located on the lower side of the slope foundation relative to the bridge cap. The support beam is connected to the top of the resistance pile. One side of the key is fixedly connected with the supporting beam, and the other side of the supporting key is fixedly connected with the bridge cap. The resistance piles provide lateral support and are arranged on both longitudinal sides of the pier, which will not affect or have little effect on the lateral deformation of the existing pier during construction, avoiding uncontrollable lateral deformation. The supporting beam provides a supporting foundation on one side and supports The force is transmitted to the resistance pile, and the support key can transmit the lateral support force to the bridge cap, which has strong support and anti-deformation ability, and improves the effect of bridge pier deformation repair.

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.
