Problems solved by technology

[0003] The purpose of the present invention is to provide a construction technology suitable for the installation of bridge erecting machines, which is used to solve the problems in the prior art due to the heavy weight of the pier top blocks. During the installation process of the bridge crane, it needs to be hoisted to the top of the pier first, which requires a high load on the crawler crane and the ground on the site after hardening. Therefore, when the geological conditions on the site are poor, it will lead to high construction costs and difficult technical problems

Embodiment Construction

[0031] The specific implementation of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art have a more complete, accurate and extended understanding of the inventive concepts and technical solutions of the present invention.

[0032] Such as Figure 1-10 As shown, the present invention provides a kind of construction technology applicable to the installation of bridge erecting machine, comprising the following steps:

[0033] Step 1: Set up a supporting structure for the bridge pier 2 where the outriggers of the bridge crane need to be installed, and the supporting structure includes a temporary support 4 on the pier top of the bridge pier 2 . In addition, the pier 2 of the rear outrigger 5 and the middle outrigger 6 of the bridge machine is also provided with a pier top frame 3 .

[0034] The structure of the temporary support 4 at the top of the pier ...

Abstract

The present invention discloses a construction technology suitable for installation of a bridge girder erection machine. The construction technology comprises the steps that firstly, a supporting structure is arranged on a pier needing to be provided with a bridge crane supporting leg, and the supporting structure comprises a pier top temporary support arranged on the pier top of the pier; secondly, bridge crane supporting legs are arranged, wherein a bridge crane rear supporting leg and a bridge crane middle supporting leg are arranged on the pier top temporary support; thirdly, a bridge crane main beam is arranged on the bridge crane supporting legs; fourthly, a hoisting crown block is installed on the bridge crane main beam; and fifthly, the pier top blocks are hoisted one by one through the hoisting crown block, and the pier top temporary supports are replaced. The weight of the pier top temporary support needing to be hoisted and other bridge erecting machine assemblies needing to be hoisted before the bridge erecting machine is installed is obviously smaller than that of the pier top block, and therefore the load requirements for equipment and the ground in the construction process are obviously lowered.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a construction technology suitable for installing a bridge erecting machine. Background technique [0002] In the traditional bridge machine installation method, before the bridge erecting machine is installed, the pier top beam section needs to be installed, and then the bridge machine outriggers, bridge machine main girder, etc. should be installed. However, due to the heavy weight of the pier top block used to carry the outriggers of the bridge erecting machine, it needs a large-load crawler crane to lift it to the top of the corresponding pier column during installation, which is more difficult for the site where the crawler crane passes. High hardness and load-bearing capacity requirements generally require hardening of the site. Even so, the poor geological conditions of the construction site still have a great impact on bridge construction. However, the tr...
