Problems solved by technology

However, since the limit structure is usually a temporary structure, such as steel structure, reinforced concrete structure, etc., it needs to be dismantled after the jacking construction is completed, which will inevitably cause a lot of waste
[0003] Affected by the lateral deflection force of the bridge, its limiting structure needs to resist a large horizontal force, and a simple column structure cannot achieve the limiting effect. Therefore, the lateral limiting structure when the bridge is lifted is usually constructed as a complex bridge structure. And foundation support is required, the cost is high, the construction period is long, and the construction of foundation support is difficult, which greatly affects the construction progress of the bridge

Abstract

The invention discloses a bridge transverse limiting device based on a tension and compression bar model and a construction method. The device comprises a vertical supporting limiting piece (1), a horizontal tying piece (41) and an oblique compression supporting piece (43). The pair of vertical supporting limiting pieces (1) are arranged on the two sides of a bridge (2) respectively, the upper ends of the pair of inclined pressed supporting pieces (43) are fixedly connected with the lower ends of the pair of vertical supporting limiting pieces (1) respectively, and obtuse included angles are formed between the inclined pressed supporting pieces (43) and the vertical supporting limiting pieces (1). The lower ends of the pair of oblique compression supporting pieces (43) obliquely extend towards the lower part of the inner side respectively and are fixed on a pier structure of a bridge (2); and the horizontal tying piece (41) is horizontally tied between the connecting nodes of the pair of inclined pressed supporting pieces (43) and the pair of vertical supporting limiting pieces (1). Stable limiting can be provided on the two sides of the bridge, and the stability and safety of the bridge in the jacking process are ensured.

Description

technical field [0001] The invention relates to a bridge construction technology, in particular to a bridge lateral limiting device and a construction method based on a tension and compression rod model. Background technique [0002] In the process of bridge jacking construction, in order to prevent the structural displacement of the bridge jacking process from developing in an unexpected direction, it is often necessary to set a limit structure around the structure, and the direction of the jacking displacement is limited by the limit structure. figure 1 And attached figure 2 shown. Due to the large load of the structure, the lateral force generated when the deflection occurs is relatively large, and the corresponding limit structure is required to have a large structural rigidity. However, since the limit structure is usually a temporary structure, such as a steel structure, reinforced concrete structure, etc., it needs to be dismantled after the jacking construction is...
