Embodiment Construction
[0074] Such as figure 1 , figure 2 and image 3 The seamless telescopic device between the main girder and the abutment with built-in corrugated steel plates is shown, which includes prefabricated steel plates and expansion joint filling layer 10 filled above the prefabricated steel plates, and the prefabricated steel plates are arranged on the construction site. On the abutment expansion joint of the bridge, the abutment expansion joint is the expansion joint left between the main girder 11 and the abutment 12 of the constructed bridge; the main girder 11 is covered with a bridge deck pavement structure, and the The outer side of the upper part of the abutment 12 is paved with pavement pavement and the inner side of the upper part is an exposed section of the abutment. A reserved installation for the installation of the prefabricated steel plate parts is formed between the bridge deck pavement structure and the pavement pavement layer. Groove, the length of the longitudina...
