Embodiment Construction
[0035] The following will describe in detail with reference to the drawings in the embodiments of the present invention.
[0036] see figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 , Figure 8 , Figure 9 , for the construction technology of large-tonnage bridge bearing replacement, the specific steps are as follows:
[0037] Build a construction platform 3 with sufficient strength, rigidity and stability, and bear vertical and horizontal thrust through scaffolding. The construction platform 3 has a construction load capacity of more than 20 tons and can withstand impact loads. The space between the construction platform 3 and the bottom of the box girder 1 is maintained at a height of 1.6m-2m to ensure the ease of operation for construction personnel. The construction platform 3 includes a translation track 4 arranged above, and the translation track 4 is flush with the bottom surface of the old support 2 of the box girder 1 .
