SYSTEM FOR DRIVING BYPASS VALVES IN RESPONSE TO ERROR OF CONCRETE HIGH PRESSURE PUMPING

摘要

PURPOSE: A system for driving bypass valves in response to error of concrete high pressure pumping is provided to protect residual pipe by colleting concrete which is not hardened because a main part in the pipe is closed when blocking and extraordinary states. CONSTITUTION: A system for driving bypass valves in response to error of concrete high pressure pumping comprises a first bypass valve(310), a second bypass valve(320), a first bypass valve control part(330), a second bypass valve control part(340), and a sensor node part(350). The first bypass valve opens and closes a first and a second moving passage. The first moving passage moves concrete from a lower floor part(315) to a high floor part(335) of a main pipe. The second moving passage discharges the concrete in the high floor part to an emergency pipe(325). The second bypass valve opens and closes a bypass passage. The bypass passage allows the concrete in the high floor part to pass through the first bypass valve and discharge to the emergency pipe. The first bypass valve control part controls the concrete moving passages of the first bypass valve.
