Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] refer to Figure 1 ~ Figure 3 , a seamless anti-seismic abutment with separate strapping plates, including transverse girders 4, seismic isolation bearings 5, bridge piers 6, pile foundations 8, retaining walls 3, split strapping plates 1 and corbels 2, the The transverse partition beam 4 is located on the pier 6, the pier 6 is located on the pile foundation 8, and the corbel 2 is located behind the retaining wall 3; for example, the corbel 2 can be located on the gravel cushion behind the retaining wall 3 .

[0028] One end of the separated board 1 is placed on the corbel 2 , and the other end is seamlessly connected with the transverse beam 4 . Expansion joints are set between the separated lap board 1 and the corbel 2, and there is a sand sliding layer 12 at the vertical lap joint; the separated lap board 1 is seamlessly connected with the transverse beam 4...

Abstract

The invention relates to a seamless anti-seismic abutment with a separation type butt strap. The seamless anti-seismic abutment with the separation type butt strap comprises a transverse partition beam, a pier, a pile foundation, a retaining wall and a sleeper beam, wherein the transverse partition beam is positioned on the pier; the pier is positioned on the pile foundation; the sleeper beam is positioned behind the retaining wall; the seamless anti-seismic abutment with the separation type butt strap further comprises the separation type butt strap; one end of the separation type butt strapis placed on the sleeper beam; and the other end of the separation type butt strap is seamlessly connected with the transverse partition beam. According to the seamless anti-seismic abutment with theseparation type butt strap, lower cost and better economy are achieved.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to a seamless anti-seismic bridge abutment with separate lap plates. Background technique [0002] In order to make the bridge span structure free to deform according to the static calculation diagram under the action of load, temperature change, concrete shrinkage and creep, the bridge needs to be equipped with supports and expansion joints running through the whole bridge transversely. On the one hand, the use of expansion joints increases the cost of bridge construction. On the other hand, the expansion joints are the weak points of the whole bridge. For example, the expansion joints and anchors are fatigued due to repeated impact loads of vehicles, and the post-maintenance work is not in place. The early damage of the bridge reduces the service life, and the investigation shows that the above-mentioned problems exist in different degrees in the expressway bridges of various cou...
