AI Technical Summary
Technical Problem
During the trench excavation process, a water pipe broke, causing pressurized water to flow into the trench, creating safety hazards and causing mechanical downtime, as well as wasting a lot of water resources and time.
Method used
Design a temporary sealing tool that includes an expansion member and a threaded rod. The threaded rod is inserted into the broken pipe through a threaded connection and rotated. The steel end cap is used to compress the rubber plug to expand and seal the pipe.
Benefits of technology
Quickly seal the water pipes to ensure construction safety, reduce water waste, improve construction efficiency, and avoid machine downtime.

Abstract
A temporary sealing tool for water supply pipes is used for temporarily sealing broken water supply pipes with small diameters. It includes an expansion member and a threaded rod, with the threaded rod threadedly connected to the axis of the expansion member. The expansion member consists of a rubber plug, an internally threaded steel pipe, and a steel handle. The rubber plug is fixed to the left end of the internally threaded steel pipe, and the steel handle is welded to the middle of the internally threaded steel pipe. The threaded rod includes a steel abutment and a threaded rod body. The steel abutment is welded to the left end of the threaded rod body, and the handle is threadedly connected to the right end of the threaded rod body. This invention utilizes the outward rotation of the threaded rod to compress the threaded rod abutment into the rubber plug, causing the rubber plug to expand and eventually fill the water supply pipe, thus achieving a water-stopping effect.
