AI Technical Summary

Technical Problem

In the prior art, in concrete spray for initial support of tunnels, the determination of the proportion of fast set agent lacks an accurate and systematic basis, resulting in unreasonable concrete settling time, affecting the support effect and construction quality.

Method used

By obtaining the real-time position of the nozzle in the tunnel and the real-time environmental factors in the tunnel, using the preset corresponding relational database and adjustment ratio database, the basic proportion and adjustment ratio of the accelerator corresponding to the position and environmental factors are determined, and the accelerator addition device is controlled based on these proportions.

Benefits of technology

The adaptive adjustment of the accelerator is achieved according to different locations of the tunnel and changes in different environments, ensuring that the added accelerator is scientific and reasonable, avoiding the problem of excessive or too little accelerator added, and improving the quality and effect of concrete spraying support.

Abstract

The invention belongs to the technical field of tunnel construction, and particularly relates to a tunnel concrete guniting accelerator control method and system and computer equipment. The method comprises the following steps: firstly, acquiring a real-time position of a spray head for guniting in a tunnel, and determining an accelerator foundation proportion corresponding to the real-time position according to a preset corresponding relationship between different positions of the tunnel considering different gravity components and the accelerator foundation proportion; meanwhile, real-time environment factors influencing the concrete setting time in the tunnel are obtained, and the accelerator adjusting proportion corresponding to the real-time environment factors is determined according to the corresponding relation between the preset different environment factors and the accelerator adjusting proportion; finally, the determined basic proportion of the accelerator is adjusted according to the determined adjusting proportion of the accelerator, and an accelerator adding device is controlled according to the adjusted proportion. The influence of gravity components of different positions of the tunnel and environmental factors influencing the concrete setting time in the tunnel on the proportion of the accelerator is fully considered, so that the added accelerator is more scientific and reasonable.
