The significance and essentiality of grouting testing for large and medium-scale water conservancy projects

Abstract

Grouting test is a test carried out before preliminary design or bidding design, which supplements the insufficient amount of exploration works in the early stage and can also improve the investigation accuracy of the project. Various parameters obtained can directly enter the analysis of the project cost and unit price to guide the completion of grouting design, and will not lead to the increase of grouting works and design changes during the construction process. Therefore, the increase of project investment and the extension of construction period are caused. The productive grouting test is the test conducted before the construction of grouting, which is to verify the rationality of the recommended parameters of grouting design. However, the unreasonable parameters of grouting may lead to major design changes, resulting in the increase of project investment and the extension of project duration. Therefore, grouting test is particularly important and necessary for water conservancy projects, especially large and medium-sized water conservancy projects.
