Description

Temporary pier

Technical Field

The utility model relates to a bridge construction field especially relates to an interim mound.

Background

In the pushing construction process of the continuous beam bridge, the negative bending moment at the supporting point is in direct proportion to the square of the span, so the increase of the bridge span can cause the increase of the internal force of the bridge. Under the condition that the section of the box girder and the strength of the prestressed steel beams are limited, in order to enable the main girder to bear larger internal force in the pushing construction process, an effective method is to arrange a temporary pier.

The steel pipe stand is widely used as a compression column in the temporary pier, the turning radius can be increased by the characteristics of the hollow section of the steel pipe stand, and the integral stability of the steel pipe stand is ensured. However, the increase of the turning radius causes the increase of the diameter-thickness ratio of the steel pipe wall of the steel pipe column, which is not favorable for the local stability of the steel pipe column. When the temporary pier does not meet the requirement of local stability due to the adopted steel pipe upright, the existing structure needs to be reinforced so as to meet the use requirement.

One prior art reinforcement technique is to pour concrete into the steel tube columns so that the steel tube columns and the concrete are stressed together. However, in the technology, the self weight has overlarge influence on the bearing capacity of the foundation, and the requirement on the axial bearing capacity of the single pile is overlarge. Meanwhile, the temporary pier built by adopting the reinforcement technology is more difficult to disassemble.
