Embodiment Construction

[0037] The technical solutions in the present invention are clearly and completely described below in conjunction with the embodiments and the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0038] An assembled bridge pier that can be replaced after an earthquake, such as figure 1 As shown, it includes a lower pier structure 1 and an upper pier structure 2 arranged in sequence from bottom to top, and the lower pier structure 1 is detachably connected to the lower end of the upper pier structure 2 .

[0039] Such as figure 2 As shown, the lower pier structure 1 includes a lower pier main body 12, a second connecting plate 15 fixed on the upper end of the lower pier main body 12, and a grouting hole 110 opened on the upper end surface of the second connecting plate 15 and communicating with t...

Abstract

The invention relates to the field of piers, in particular to a fabricated replaceable combined pier after an earthquake. The bridge pier comprises a lower bridge pier structure and an upper bridge pier structure which are sequentially arranged from bottom to top, and the lower bridge pier structure is detachably connected to the lower end of the upper bridge pier structure. During actual use of the pier, the upper portion of the pier is connected with the bridge body, and the lower portion of the pier is fixed to the ground. When an earthquake occurs, the damaged position of the bridge pier is mainly concentrated on the lower portion of the bridge pier. Therefore, the bridge pier is designed into the upper bridge pier structure located on the upper portion of the bridge pier and the lowerbridge pier structure located on the lower portion of the bridge pier, and detachable connection is formed between the upper bridge pier structure and the lower bridge pier structure. When the lowerbridge pier structure is damaged, only the lower bridge pier structure needs to be replaced and the upper bridge pier structure needs to be reserved during maintenance, and maintenance difficulty andmaintenance cost are reduced. And the upper pier structure is reserved during maintenance, so that the main beam connected with the upper pier structure cannot be damaged due to maintenance, and the safety of maintenance personnel can be guaranteed.

Description

technical field [0001] The invention relates to the field of bridge piers, in particular to an assembled bridge pier that can be replaced after an earthquake. Background technique [0002] Bridges are important hubs of traffic lifelines. Once a bridge is damaged during an earthquake, it is easy to cause traffic interruption and turn the affected city into an "earthquake isolated island". As a result, rescuers cannot arrive in time, causing immeasurable casualties and economic losses. In addition, it is extremely difficult to repair bridges after earthquakes. How to quickly repair bridges after earthquakes is an inevitable requirement for the research and development of bridge seismic performance. [0003] Bridge piers are the main components of bridges and play a vital role in the overall seismic performance of bridges. The pier is used to support the main body of the bridge. The upper part of the pier is connected to the main body of the bridge, and the lower part of the b...
