Abstract

The invention discloses a device and a method for measuring and controlling the diffusion range of cement-based grout in covering layer grouting, and relates to the technical field of grouting engineering. The device comprises multiple sets of pH electrodes which are arranged in corresponding monitoring holes respectively and used for obtaining pH values at multiple coordinate positions in each monitoring hole in real time; a pH data acquisition instrument which is connected with the plurality of groups of pH electrodes and is used for acquiring the pH value sent by each pH electrode in real time; and a slurry diffusion data management system which is connected with the pH data acquisition instrument and is used for processing the pH values sent by the pH data acquisition instrument in real time, determining a slurry diffusion position and drawing a cement-based slurry diffusion range profile diagram at any moment according to the slurry diffusion position. According to the invention, the diffusion range of the cement-based slurry in the grouting process of various covering layers can be effectively monitored.

Description

technical field [0001] The invention relates to the technical field of grouting engineering, in particular to a device and method for measuring and controlling the diffusion range of cement-based grout in grouting of covering layers. Background technique [0002] Overburden is widely distributed in China, and many dam foundations are built on the overburden foundation. Due to the special geographical conditions and complex genetic types, the engineering properties of the Quaternary overburden in different regions of China are quite different. For example, in the southwestern region of China, which is rich in hydropower resources, the covering layer is mainly composed of boulders, crushed stones, and silty sands, which have the characteristics of loose structure, coarse particles, and strong water permeability, while in the relatively arid central and western regions of China, The overburden is mainly composed of newly accumulated loess from the Holocene to the new loess fro...
