Small-section tunnel portal short roadbed beam erecting construction method
The invention relates to a small-section tunnel portal short roadbed girder erection construction method, which relates to the technical field of girder erection construction, and comprises the following construction steps: detection: the working height of a bridge girder erection machine is Q, the clearance height H of a tunnel is measured, and whether H is greater than or equal to Q is detected; if yes, erection: a bridge girder erection machine is in place for girder erection construction; if not, adjusting: reducing the elevation of the rail surface of the tunnel portal rail or/and the working height of the bridge girder erection machine, and carrying out an erection procedure until the condition is met. According to the method, the headroom height of the tunnel is detected to obtain data H, so that whether H is greater than or equal to Q is judged; if yes, the bridge girder erection machine is in place for girder erection construction; and when the condition is not met, adjustment is carried out, one or two modes of reducing the height of the rail surface of the tunnel portal rail and the working height of the bridge girder erection machine are carried out at the same time until the condition is met, the convenience during adjustment is improved, and therefore the construction efficiency of girder erection is improved.
本申请涉及一种小断面隧道口短路基架梁施工方法，涉及架梁施工的技术领域，包括以下施工步骤：检测：架桥机的工作高度为Q，测量隧道净空高度H，检测是否满足H≥Q；满足，架设：架桥机就位进行架梁施工；不满足，调整：降低隧道口轨道轨面标高或/和架桥机的工作高度，直至满足后进行架设工序。本申请通过对隧道净空高度进行检测得到数据H，以此来判断是否满足H≥Q；当满足时，架桥机就位进行架梁施工；而当不满足时，进行调整，通过降低隧道口轨道轨面高度和架桥机的工作高度这两种方式中的一种或两种同时进行，直至满足条件，提高了调节时的便利性，因此提高了架梁的施工效率。
