Embodiment Construction

[0039] The present invention will be further described below in conjunction with the specific embodiments in the accompanying drawings.

[0040] refer to Figure 1-24 , a walking-type pushing construction method for large-scale components, synchronously jacking up large-scale components through single or multiple sliding mechanisms 4 arranged at longitudinal intervals or transverse intervals or connected; The track 1 moves continuously, and the stroke is only limited by the longitudinal dimension of the construction platform plane slideway. Preferably, the sliding mechanism 4 moves continuously along the slideway 1 for a distance of more than 1 meter synchronously. The length of the slideway 1 is determined according to the beam shape of the large component. , the size of the pier body, the length of the slideway girder, and the construction requirements. For example, the truss girder component of the main bridge of a project has a length of 26 meters. is 32 meters, while the...

Abstract

The invention discloses a walking type pushing construction method for a large component, relates to the technical field of large component pushing, and solves the technical problems of low efficiency and poor safety. The method comprises the steps that the large component is jacked up through a sliding mechanism of at least one walking type pushing unit, and the sliding mechanism is continuously moved along a sliding way through a driving mechanism; and then the sliding mechanism descends, the large component is temporarily supported on a buttress mechanism, after the sliding mechanism descends to be separated from the large component, the sliding mechanism is moved reversely, and the jacking, moving and descending processes are repeated till the moving distance required by pushing construction is completed. The invention further discloses application of the method. The sliding mechanism synchronously and continuously moves through the driving mechanism, the single-time maximum effective stroke can be larger than 2 meters, the stroke is far larger than the stroke of a jack of traditional walking type equipment, efficiency is high, the jacking frequency of the jacking jack is greatly reduced, the service life of the equipment can be prolonged, and the use safety of an oil supply system of the equipment can be improved.

Description

technical field [0001] The present invention relates to the technical field of large component jacking, more specifically, it relates to a large component walking type jacking construction method and its application. Background technique [0002] At present, there are two types of equipment commonly used for pushing large-scale components, such as bridges. One is walking equipment, which uses a set of rigid pushing devices. In order to correct the deviation, the longitudinal moving structure pushes the main girder, and the stroke of the main girder is the stroke of a jack, which has the following problems: the walking equipment has the problems of short step distance, frequent ups and downs, and low efficiency; the other is the drag type The equipment adopts a set of flexible jacking device, which includes traversing and jacking mechanisms. It is necessary to install the corbel structure and anchor plate on the main beam, install the reaction force structure on the slideway,...
