Construction method of movable temporary temporary steel bridge with adjustable length
The invention discloses a construction method of a length-adjustable movable temporary temporary steel bridge, which comprises the following steps of: transversely splicing a plurality of bailey beam units side by side to form a temporary steel bridge main body according to the maximum transverse width of a top beam of a foundation pit; then the temporary steel bridge body is erected on the surface of the top beam, and then connection construction of the temporary steel bridge body and the surface of the foundation pit is conducted; the temporary steel bridge is moved from the surface of the foundation pit crown beam with the large transverse width to the surface of the foundation pit crown beam with the small transverse width, when the temporary steel bridge is moved, a connecting structure of a temporary steel bridge body and the surface of the foundation pit is removed firstly, then the temporary steel bridge is lifted till the bottom face of the temporary steel bridge is higher than the surface of the foundation pit, then a guide rail is laid on the surface of the foundation pit, and the temporary steel bridge is lowered to the guide rail; and then the bailey beam units at the two ends of the temporary steel bridge body are dismantled, then the guide rails are dismantled, the temporary steel bridge body is lowered to the surface of the top beam, and finally connection construction of the temporary steel bridge body and the surface of the foundation pit is completed. The temporary steel bridge has the effect of improving the installation efficiency of the temporary steel bridge.
本申请公开了一种长度可调节的移动式临时钢便桥的施工方法，通过根据基坑冠梁最大横向宽度，将若干个贝雷梁单元横向并排拼接成钢便桥主体；然后将钢便桥主体架放在冠梁表面，然后进行钢便桥主体与基坑表面的衔接施工；将钢便桥从横向宽度大的基坑冠梁表面移动至横向宽度小的基坑冠梁表面，移动钢便桥时，先拆除钢便桥主体与基坑表面的连接结构，然后上提钢便桥，直至钢便桥底面高度高于基坑表面，接着在基坑表面铺设导轨，将钢便桥下放至导轨上，接着拆除钢便桥主体两端的贝雷梁单元，然后拆除导轨，将钢便桥主体下放至冠梁表面，最后完成钢便桥主体与基坑表面的衔接施工。本申请具有提高钢便桥的安装效率的效果。
