Problems solved by technology

[0002] With the increase of the service life of the bridge, the deviation of the bearing or the damage of the bearing of the existing bridge is more and more common and prominent, which affects the normal use of the bridge. It is necessary to lift the bridge, and then replace the bearing, Pad stone repair and other maintenance construction operations, so there is an urgent need for a safe and convenient construction operation platform to complete the above work
[0003] At present, the jacking platforms used for the replacement of bridge supports mainly include: (1) Using the original bridge pier and cover beam as the jacking reaction support platform, this scheme is convenient for construction, but it is affected by the limitations of the bridge itself and the construction environment on site. Not applicable to all types of bridges; (2) Set up supporting piers and brackets as the jacking reaction support platform, which requires a large construction investment and poor reliability; The construction of this scheme is difficult and the reliability is difficult to guarantee; (4) After enlarging the diameter of the original bridge pier and increasing the area of ​​the pier top, the bridge pier column is used as the jacking reaction force support platform. This scheme has high reliability, but the construction It is cumbersome and will cause damage to the bridge structure, and the maintenance period after concrete pouring is long

Abstract

The invention discloses an operation platform for replacing a support saddle of a bridge, and is characterized in that the operation platform comprises a pier pillar hoop, a plurality of rib plates and a crown plate, wherein the pier pillar hoop is sleeved on the periphery at the upper end of the pier pillar; the crown plate adopts a circular structure and is arranged at the tops of both the pier pillar and the pier pillar hoop; the rib plates are uniformly distributed at the periphery of the pier pillar hoop; the upper parts of the rib plates are connected with the crown plate; and the pier pillar hoop, the rib plates and the crown plate are welded and fixed with each other. The platform is erected at the top of the pier pillar of the bridge to enlarge the area of the construction working face at the top of the pier pillar of the bridge; and serving as an operation platform for replacing the support saddle of the bridge or repairing padstone, the operation platform provided by the invention has the advantage that the reliability is high, and as processes such as building ribs in the pier pillar of the bridge are not required, damage on the pier pillar of the bridge is small.

Description

technical field [0001] The invention relates to an operating platform for replacing bridge supports, in particular to an operating platform erected on the top of a pile-type pier, and belongs to the technical field of bridge maintenance and construction equipment. Background technique [0002] With the increase of the service life of the bridge, the deviation of the bearing or the damage of the bearing of the existing bridge is more and more common and prominent, which affects the normal use of the bridge. It is necessary to lift the bridge, and then replace the bearing, Pad stone repair and other maintenance construction operations, so there is an urgent need for a safe and convenient construction operation platform to complete the above work. [0003] At present, the jacking platforms used for the replacement of bridge supports mainly include: (1) Using the original bridge pier and cover beam as the jacking reaction support platform, this scheme is convenient for construct...
