Embodiment 1

[0026] like Figure 1~2 As shown, a jacking bracket system for segmental installation of bridge towers according to the present invention is composed of a fixed bracket 1, a limit device 2 and a jacking device 3, and the fixed bracket 1 is fixed on the foundation 6 around the bridge tower. , the inside of the fixed support 1 is symmetrically provided with a limiting device 2 for limiting the bridge tower in the center, and the fixed support 1 or the limiting device 2 is provided with a jacking device 3, and the bottom of the jacking device 3 is fixedly connected with the bridge tower ; Wherein, there are 4 jacking devices 3, which are arranged symmetrically along the periphery of the bridge tower. Wherein, the limit device 2 inside the fixed support 1 has adjustability, the fixed support 1 and its limit device 2 can adjust the position of the bridge tower, so that the bridge tower is upright; the fixed support 1 is fixed on a firm foundation, and the fixed support 1 The stren...

Embodiment 2

[0035] In the above step 4, use the fixed bracket 1 as a support, use the lifting device 8 to lift the bridge tower section 5 to be installed, place it vertically on the translation trolley 7, and move the translation trolley 7, so that the bridge tower section 5 to be installed enters the Install below the pylon section 4. Other structures and construction techniques of the jacking support system are the same as in Embodiment 1, and will not be described in detail here.

Abstract

The invention relates to a jacking bracket system for segmented mounting of a bridge tower and a construction process thereof, belonging to the field of bridge engineering. The segmented-mounted jacking bracket system is formed by matching fixed brackets, limiting devices and jacking devices. The construction process is characterized in that the brackets are fixed on the circumference of the design position of the bridge tower; a top section for mounting the bridge tower is arranged in the brackets and is lifted to a certain height by using the jacking devices; the height is lower than the height of the brackets and higher than the height of the section of the bridge tower; the circumference of the bridge tower is fixed by using the limiting devices on the bracket, so that the bridge tower is erected in a suspended state; a second section is spliced at the lower end of the top section; two spliced sections are jacked to a certain height by using the jacking devices; a third section isspliced below the spliced two sections; all sections are sequentially spliced; and finally, a bottom section of the bridge tower is connected with a foundation to finish mounting of the bridge tower.The jacking bracket system and the construction process thereof can be used for saving an auxiliary material for mounting the bridge tower; meanwhile, the mounting operation height is reduced and theconstruction safety is improved.

Description

technical field [0001] The invention relates to a support system for bridge construction and a construction process thereof, in particular to a jacking support system and a construction process for segmental installation of bridge towers, and belongs to the field of bridge engineering. Background technique [0002] Bridge towers or piers are the main components of bridges, some reaching hundreds of meters high. At present, the known prefabricated bridge towers are constructed by a segmental installation method or integrally hoisted. The construction process principle of the segmental installation method is to use a crane higher than the bridge tower to first fix the bottom section on the foundation, and then assemble it segment by segment from bottom to top to increase the height of the structure; each segment of the assembly is completed, and the bridge tower can be independently Stablize. The technical principle of overall hoisting is to use a crane higher than the bridg...
