Description

Technical Field

[0001] The utility model belongs to the technical field of bridge maintenance, in particular to a bridge anti-settling structure. Background Art

[0002] Bridges generally refer to structures built on rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology, or meet other transportation needs to make passage more convenient. During the construction of bridges, soft foundation sections are often encountered. With the long-term use of bridges or vehicle overload, the bridge piles at different locations will have uneven settlement problems, which can easily cause deformation, cracking, or even breakage of the bridge.

[0003] The Chinese utility model patent with publication number CN219060104U and published on May 23, 2023 discloses an anti-settlement device for highway bridge pile foundation, including a pile body and a supporting pedestal, the supporting pedestal is connected to the top of the pile body by integral casting, the pile body is connected to the middle position of the bottom of the supporting pedestal, the outer ring of the pile body below the supporting pedestal is integrally connected with a ring block, the outer ring of the pile body directly below the ring block is sleeved with a support plate, and the bottom surface of the ring block is supported and abutted against the upper surface of the support plate, and auxiliary piles are vertically arranged at the four corners of the bottom of the support plate.

[0004] The above patent constructs auxiliary piles evenly vertically on the outer circle of the pile body, so that the upper support and locking support plate with a through hole are supported. During use, the support plate is subjected to the anti-settlement support force from a larger area of ​​soil, thereby ensuring the overall anti-settlement effect of the pile body. However, it can only prevent the settlement of the bridge to a certain extent and cannot offset the settlement. Utility Model Content
