Embodiment Construction

[0020] Depend on figure 1 , figure 2 , image 3 with Figure 4 A construction method for rapid construction of cast-in-place continuous beams with brackets shown, the construction steps are:

[0021] Next to the pier, support 6 is installed next to the pier, and the support 6 next to the pier is carried out in parallel with the foundation construction of the bridge. Build bridge support 9. When the support 6 next to the pier is constructed, the strip foundation 7 is first established, and the steel pipe columns 4 are set up on the strip foundation 7. The steel pipe columns 4 are connected by the connection system 5, and the steel pipe columns 4 utilize the pre-embedded pier body 10 during foundation construction. items connected to it. Set up a pile top distribution beam 3 as a slideway at the top of the steel pipe column 4 between the pier side support 6 and the bridge position support 9, then set up a base formwork platform 2 on the pile top distribution beam 3 of the ...

Abstract

The invention discloses a construction method for the rapid construction of a support cast-in-situ continuous beam. The method is that a pier-side support is installed beside a pier, the foundation construction of the pier-side support and a bridge beam are conducted in parallel, a pouring support is established after the foundation construction is completed, a bottom mold platform is establishedon the pier-side support, the installation of continuous beam templates and the overall binding of steel bars are conducted on the bottom mold platform, the bottom mold platform and the bound continuous beam templates are transversely moved to the pouring support and finally continuous beam concrete is poured. The construction method can satisfy the rapid construction requirement that the continuous beam templates and the steel bars are integrally and transversely moved.

Description

technical field [0001] The invention relates to a bridge construction method, in particular to a construction method for rapid construction of cast-in-place continuous beams with supports. Background technique [0002] The conventional construction method of cast-in-place continuous beams with brackets is to install brackets at the pier, and to construct continuous beams on the brackets. The support construction at the pier has the following characteristics: [0003] (1) The construction of the support at the pier position must be carried out after the construction of the pier body is completed, and then the construction of the support and the platform is carried out, and the continuous beam steel bars and prestressed pipes are installed after the formwork is set on the platform and the elevation is adjusted, and the concrete is poured after passing the test . [0004] (2) The construction period of the support at the pier position is relatively long, and the installation ...
