SAND COLLECTION PIPE CONDUIT INSTALLATION STRUCTURE IN SAND BASIN

摘要

PROBLEM TO BE SOLVED: To provide a sand collection pipe conduit installation structure capable of: reducing labor and cost for drilling and piping works; and shortening working time for running water through, shutting off water supply to and adjusting flow rates in respective pipe conduits with sand collection valves installed thereon.SOLUTION: A sand collection pipe conduit installation structure in a sand basin: connects pipe conduits leading to a water supply pump common to respective nozzles installed in a main trough and a plurality of areas separating a bottom surface of a sand basin and to nozzle headers; and has sand collection valves for running water through, stopping water supply to and adjusting flow rates in respective pipe conduits. The pipe conduits are: assembled in areas immediately below slots on a ceiling wall covering an upper surface of the sand basin; and upwardly extended through the slots to positions above the ceiling wall with the assembled pipe conduits in an aligned state. The sand collection valves are installed on the pipe conduits extended above the ceiling wall in the aligned state.SELECTED DRAWING: Figure 5
