Embodiment Construction
[0033] Embodiment of the present invention: adopt the mobile tower crane of existing market, mobile tower crane comprises tower body 1 and walking platform 2. Transport the mobile tower crane to the starting point of bridge construction. The reinforced concrete girder bridge is built according to the length of one span. 3, start to install the walking track 4, so as to walk to the next span. The length of the walking track 4 is 50m (standard span box girder length). Pull, set the backing plate 5 on the bridge deck 3, set the sleepers 6 on the backing plate 5, and fix the running track 4 on the sleepers 6 through rivets, and the backing plate 5 is made of steel plate, which is used to ensure that the force on any position on the total length of the walking track 4 is uniform Reliable, avoiding the influence of superelevation on bridge deck 3. Walking track 4 needs 2 sections at least, and one section is used for mobile tower crane walking, and another section is transported to...
