Abstract

The invention discloses a method for optimizing the technological parameters of prestressed duct circulation grouting construction. The method includes the steps of establishing the geometric model of a prestressed duct according to the parameters of the prestressed duct; conducting mesh generation on the flow field of the prestressed duct, and establishing the calculation model of the prestressed duct; setting up numerical simulation calculation conditions according to material parameters, and calculating to obtain the simulation results of the circulation grouting construction of the prestressed duct; changing the parameters of prestressed duct and/ or the numerical simulation calculation conditions, obtaining multiple simulation results, and screening the construction parameters corresponding to the best simulation result. The method uses an analogue simulation technology to establish the prestressed circulation grouting model consistent with an actual system, simulate a circulation grouting process and optimize the technological parameters of the circulation grouting construction according to the simulation results after multiplicating simulation, thereby providing optimization guidance for the circulation grouting construction, and reducing grouting quality defects which likely appear in experienced construction in construction sites.

Description

technical field [0001] The invention belongs to the field of prestressed bridge construction, and in particular relates to a method for optimizing process parameters of prestressed channel circulation grouting construction. Background technique [0002] Prestressed channel circulation grouting is a key process in the construction of prestressed concrete bridges. How to ensure the construction quality of prestressed channel circulation grouting is a key technical issue that needs to be considered in the process of prestressed bridge construction. Prestressed pipes are also called corrugated pipes, and their grouting compactness has an important impact on the durability of bridges. During the construction process of circulating grouting in prestressed channels, it is an important guarantee to improve the grouting quality and grouting efficiency to design and adjust the construction process parameters such as grouting material viscosity, grouting pressure and grouting time. Ac...
