Embodiment Construction
[0028] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail with reference to the accompanying drawings.
[0029] Such as figure 2 As shown, a semi-rigid integral abutment bridge supported by concrete piles includes a bridge end beam 3, a pile cap 2 and a concrete pile 1 inserted into the ground surface as a supporting pile, and the weak axis of the concrete pile 1 is subjected to bending , and the end beam 3 adopts a semi-rigid connection structure. The semi-rigid connection structure refers to a connection structure in which neoprene rubber 5 is filled at the joint between the pile cap 2 and the end beam 3 , and the two are connected by the main reinforcement 6 in the concrete pile 1 . The semi-rigid connection structure between the pile body 2 and the end beam 3 increases the longitudinal deformation capacity of the bridge, increases the allowable bridge length...
