Bridge jacking transverse limiting device
The invention provides a bridge jacking transverse limiting device, so as to solve the problems that an existing bridge transverse limiting device is large in occupied space, and the existing bridge body transformation work amount is large. The device mainly comprises underground anchor rods, foundation beams and a ground frame which are located below a manhole in the bottom of a bridge beam and distributed from bottom to top. The underground anchor rod is vertically inserted into the foundation; the upper part is exposed out of the foundation by a certain height; the part, exposed out of thefoundation, of the underground anchor rod is fixedly connected into the foundation beam for fixing a foundation beam and a foundation; the ground frame is mainly composed of a plurality of stand columns. The stand columns are evenly distributed in the bridge width direction. The lower parts of the stand columns are fixedly connected with the foundation beams; the upper parts are inserted into manhole holes in the bottom of the bridge beam, certain gaps are formed between the stand columns and the manhole holes, in addition, a plurality of transverse beams are connected between every two adjacent stand columns, pull rods are further connected between the ground frame and the foundation beam, and the pull rods are obliquely arranged between the outer sides of the stand columns at the left end and the right end of the ground frame and the foundation beam.
为了解决现有桥梁横向限位装置空间占用大、对现有桥体改造工程量大的问题，本发明提供了一种桥梁顶升横向限位装置，主要包括位于桥梁梁底人洞下方的自下而上分布的地下锚杆、基础梁以及地面框架，所述地下锚杆竖直插入地基中，上部漏出地基一定高度，并且地下锚杆漏出地基的部分固定连接于基础梁内，用于基础梁与地基之间的固定，所述地面框架主要由若干个立柱组成，立柱沿桥梁宽度方向均匀分布，立柱下部与基础梁固定连接，上部插入到桥梁梁底人洞孔内，并且立柱与人洞孔之间设有一定的间隙，此外，相邻的两立柱之间连接有若干个的横梁，所述地面框架与基础梁之间还连接有拉杆，所述拉杆倾斜设置于地面框架左右两端立柱的外侧与基础梁之间。
