AI Technical Summary
The existing method of filling geological cavities has the problem of incomplete filling, which can create cavities at the top, becoming weak points in the dam foundation and posing a safety risk.
The system employs a control system that includes a concrete pumping mechanism and a vibration venting mechanism. The vibration venting mechanism works in conjunction with a vent pipe and a vibration generating component. The vent pipe floats and bends with the concrete, and the vent hole always faces the top. The vibration generating component provides mechanical vibration to ensure that the concrete is completely filled.
The geological exploration tunnel was completely filled, eliminating the top cavity and improving the bearing stability and long-term operational safety of the hydropower project dam foundation.
