Embodiment Construction

[0031] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0032] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

The invention relates to a non-expansion joint bridge abutment suitable for large deformation and a construction method thereof. A non-expansion joint bridge abutment suitable for large deformation comprises: a foundation; a bridge pier; At one end, a first opening is provided on the side of the main girder away from the bridge pier; a retaining wall is connected to the foundation and spaced apart from the bridge pier, and the top side of the retaining wall is flush with the top side of the main girder, and the retaining wall faces the side of the main girder A second opening is provided, and the second opening communicates with the first opening to form an accommodating groove; the first buffer piece is inserted in the accommodating groove; and the bridge pavement layer is arranged on the top side of the retaining wall. A construction method for a bridge abutment without expansion joints suitable for large deformations comprises the following steps: pouring a foundation; pouring bridge piers; pouring a main girder; pouring a retaining wall; . The above-mentioned bridge abutment and its construction method suitable for large deformation without expansion joints, the first buffer can better absorb the longitudinal deformation of the bridge.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a bridge abutment suitable for large deformation without expansion joints and a construction method thereof. Background technique [0002] Most of the existing abutments of bridges without expansion joints suitable for large deformation are embedded in the backfill of the abutment to form an organic whole with the backfill to meet the deformation requirements of the bridge. The parameters and indicators of the backfill are high, and the construction technology is high, and the scope of the longitudinal deformation of the bridge is limited. Contents of the invention [0003] Based on this, it is necessary to provide a non-expansion joint bridge abutment suitable for large deformation and its construction method for the technical problems of high bridge construction technology requirements and limited deformation range. [0004] A non-expansion joint bridge abutment ...
