Abstract

The invention belongs to the technical field of bridge construction, and particularly discloses a double-limb thin-wall super high-pier temporary steel collar beam construction method. The double-limbthin-wall super high-pier temporary steel collar beam construction method includes the following steps that first, an assembling partis pre-buried in a pier stud; second, a steel collar beam is assembled on site; third, the steel collar beam is lifted to an assembling position; and fourth, a branch collar beam is made to slide to make the outer side of the branch collar beam stick to the pier stud, and then is connected with the assembling part and a hanging part. According to the double-limb thin-wall super high-pier temporary steel collar beam construction method, the construction method ofsteel collar beam field assembling and then lifting is adopted to solve the problem of long working time of personnel in a high altitude during the construction of an existing reinforced concrete collar beam, and the function of seismic resistance can be achieved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a construction method for a temporary steel tie beam of a thin-walled superhigh pier with two limbs. Background technique [0002] The terrain in the west of my country is steep, and the terrain is mostly ravines and steep slopes. There are a large number of high piers and even super high piers with long span continuous rigid frame bridges. Among them, double-leg thin-walled piers (referred to as double-leg piers) are commonly used piers for this type of bridge. . In order to strengthen the overall rigidity of the double-limb pier, a tie beam will be added between the two pier columns to act as a tie rod and connect the two pier columns as a whole for stress. [0003] Existing tie beams are usually reinforced concrete tie beams. Traditional reinforced concrete tie beams have the following disadvantages: 1. Reinforced concrete tie beams are all cast-in-place, requiring...
