AI Technical Summary

⚠Technical Problem

During vacuum preloading construction, the monitoring pipes become clogged due to deep soil displacement and settlement, affecting data acquisition. This is especially true in areas with soft soil treatment where monitoring data is interrupted and replacement is costly.

⚗Method used

A dredging device for monitoring pipes in soft soil treatment is designed. It utilizes an electric telescopic rod and a water pump system, combined with a stirring motor and agitating drill bit, to dredge the monitoring pipes by flushing and breaking up the silt with water pressure.

🎯Benefits of technology

Effectively removes blockages inside the monitoring pipe, ensuring data continuity, reducing construction costs, and improving the reliability and security of monitoring data.

Abstract

This utility model relates to the field of geotechnical engineering safety monitoring technology, and in particular to a dredging device for a monitoring pipe in soft soil foundation treatment, comprising a support frame; an electric telescopic rod and a water pump are provided on the support frame; a dredging component is installed at the end of the electric telescopic rod; this utility model uses the electric telescopic rod to lower the equipment box and connecting water pipe together into the monitoring pipe, starts the stirring motor and water pump, and the stirring drill bit can break up the silt to facilitate the continued downward movement of the installation box. At the same time, the water pump works to transport water through the connecting water pipe to the adjusting nozzle joint, and uses water pressure for flushing. Due to the action of the adjusting plate and the elastic isolation sleeve, the mud and sand at the bottom of the pipe are flushed out of the monitoring pipe opening in the form of mud slurry, achieving the purpose of cleaning the hole.
