Width splicing bridge and settlement compensation method thereof
According to the widened bridge and the settlement compensation method thereof provided by the embodiment of the invention, the upper and lower structures of the existing bridge body and the widened bridge body are separated, only the bridge concrete pavement layers are mutually connected, and the strain detection device is arranged at the top of the bridge floor concrete pavement layer corresponding to one side, close to the existing bridge body, of the expansion joint; the strain value of the bridge concrete pavement layer is detected; meanwhile, the settlement compensation device for the bridge is arranged between the bridge support of the widening bridge body and the upper top face of the bridge abutment, bridge settlement compensation is conducted according to the detection result of the strain detection device, and active compensation of settlement of the newly-built widening bridge body abutment in the bridge widening project is achieved by arranging the settlement compensation device for the bridge; the size of an abutment foundation is not required to be increased or rigidity treatment is not required to be performed on a bridge foundation for reducing settlement of a newly-built bridge abutment, so that the bridge cost is reduced; the device and the component are simple and reliable in structure, no technical difficulty exists in construction, and good economical efficiency, reliability and feasibility are achieved.
本申请实施例中提供了一种拼宽桥梁及其沉降补偿方法，既有桥梁梁体和拼宽桥梁梁体的上下部结构分离，仅将桥梁混凝土铺装层相互连接，在伸缩缝靠近既有桥梁梁体一侧所对应的桥面混凝土铺装层顶部设置应变检测装置，对桥梁混凝土铺装层的应变值进行检测；同时，在拼宽桥梁梁体的桥梁支座与桥梁墩台的上顶面之间设置桥梁用沉降补偿装置，根据应变检测装置的检测结果进行桥梁沉降补偿，其通过设置桥梁用沉降补偿装置实现桥梁拼宽工程中新建拼宽桥梁梁体墩台沉降的主动补偿，无需为减小新建桥梁墩台沉降量而增加墩台基础尺寸或对桥梁地基进行刚度处理，降低桥梁造价；装置、构件构造简单可靠，施工无技术难点，具有良好的经济性、可靠性、可行性。
