技术领域Technical field
本发明涉及桥梁工程施工技术领域,具体地说,是涉及一种柔性桥墩水平分隔断缝的施工方法及其施工装置。The invention relates to the technical field of bridge engineering construction, in particular to a construction method and a construction device for a horizontal joint broken joint of a flexible bridge pier.
背景技术Background technique
随着我国经济的不断发展,对于城市桥梁建设质量的要求也越来越高,且对桥梁的景观性的要求也越来越高,使得桥梁成为一座城市的一道风景,甚至是成为一座城市的名片。With the continuous development of China's economy, the requirements for the quality of urban bridge construction are getting higher and higher, and the requirements for the landscape of bridges are getting higher and higher, making the bridge a landscape of a city, even becoming a city. business card.
目前,大部分的桥梁为多跨桥梁,一般的多跨桥梁的两端会设置刚性较大的桥台,而中墩则均设置为柔性桥墩,使得当桥墩在受到墩顶推力作用的时候,能够在安全的范围内发生较大的水平位移,并且保证在顺桥的方向上,桥梁的桥墩之间的水平联系被完全隔断,使得各桥墩单独承受桥梁上传来的制动力或牵引力。此外,由于桥墩的水平推力是按各墩的刚度分配,使得分配到各个桥墩上的水平推力很小,保护桥梁使用的安全性。At present, most of the bridges are multi-span bridges. Generally, the multi-span bridges are provided with rigid abutments at both ends, and the middle piers are all set as flexible piers, so that when the piers are subjected to the jack thrust, Large horizontal displacement can occur within a safe range, and the horizontal connection between the bridge piers is completely blocked in the direction of the bridge, so that each pier alone receives the braking force or traction force generated by the bridge. In addition, since the horizontal thrust of the pier is distributed according to the stiffness of each pier, the horizontal thrust distributed to each pier is small, and the safety of the bridge is protected.
然而,为了保证桥梁的景观性,一般会在桥墩的外侧设置装饰块,以对桥梁起到装饰作用,而为了使得装饰块能够正常使用,需要保证装饰块不参与桥墩的整体受力。但是,由于桥墩在受到水平推力时会发生较大的水平位移,往往使得装饰块或多或少会受到桥墩上的水平推力的波及,导致装饰块的损坏,存在安全隐患。However, in order to ensure the landscape of the bridge, a decorative block is generally arranged on the outer side of the pier to decorate the bridge, and in order to make the decorative block can be used normally, it is necessary to ensure that the decorative block does not participate in the overall stress of the pier. However, due to the large horizontal displacement of the pier when subjected to horizontal thrust, the decorative block is often more or less affected by the horizontal thrust on the pier, resulting in damage to the decorative block, which poses a safety hazard.
而目前常规的做法是在成型的装饰块上切割出水平缝,以尽量减少装饰块受到的桥墩上的水平推力,但是,该施工方式切割出来的水平缝存在深度浅、切割难度大、成缝的尺寸和效果无法保证、施工安全风险高以及成本高等问题。此外,由于切割出来的水平缝的深度浅,使得装饰块还是 会受到桥墩上的水平推力,导致装饰块容易损坏,存在安全隐患。At present, the conventional practice is to cut horizontal seams on the formed decorative blocks to minimize the horizontal thrust on the piers received by the decorative blocks. However, the horizontal seams cut by the construction method have shallow depth, difficult cutting, and seaming. The size and effect are not guaranteed, the construction safety risks are high, and the cost is high. In addition, due to the shallow depth of the cut horizontal seam, the decorative block will still be subjected to the horizontal thrust on the pier, which will cause the decorative block to be easily damaged, posing a safety hazard.
