Fluid analogue simulation preloading construction method of full framing

Abstract

The invention relates to the technical field of fluid analogue simulation preloading of full framings, and discloses a fluid analogue simulation preloading method of a full framing. The method comprises the following construction steps: 1) laying bottom templates, web templates and end templates on the full framing; 2) stacking steel bar materials on the web templates; 3) covering the bottom templates, the web templates, the concrete-iron materials and the end templates by utilizing waterproof cloth so as to form a water-tank structure; 4) injecting water in the water-tank structure, and performing preloading monitoring; and 5) after finishing preloading monitoring, draining water in the water-tank structure. The fluid analogue simulation preloading construction method of a full framing, provided by the invention, has the advantages that materials are saved, and the construction cost is reduced; the construction time is shortened, and other equipment materials are saved; vertical loads are applied on the full framing, and horizontal force generated to a supporting system during concrete pouring is simulated, so that the web templates are prevented from deforming and bursting during concrete pouring, and a uniform preloading effect can be reached.

Description

technical field [0001] The invention relates to the technical field of fluid simulation and simulated preloading of full-wall supports, in particular to a construction method for full-wall support fluid simulation and simulated preloading. Background technique [0002] Continuous box girders in highways and urban bridges are mostly constructed by cast-in-place support with full support. The stability and deformation of full support are the key to the success of cast-in-place beam construction with full support. The preloading of the full support is mainly to observe the elastic and non-elastic deformation of the full support and the foundation under the design constant load. After preloading, check the stability of the full-wall support, basically eliminate the inelastic deformation of the full-wall support, obtain relevant data that needs to be adjusted, ensure that the deformation of the full-wall support during the concrete pouring process is within the allowable range, a...
