Constructing method and control system for collector well building

摘要

The present invention relates to a method of constructing an underground collector well for a building, capable of installing a collector well installed in a building above the level of underground water to inhibit the discharge of underground water while controlling the level of underground water through the collector well, and a method of controlling the level of underground water. According to the present invention, the method comprises the following steps: installing a rebar frame of a primary collector well having a cylindrical space part on one side of a rebar frame of a ceiling slab by placing rebars of the primary collector well; installing a cylindrical sleeve including a cutoff protrusion and a square steel plate including round bars installed on a flange and in upper and lower holes vertically in the cylindrical space part of the ceiling slab of the primary collector well; covering the edge of the square steel plate and the flange of the cylindrical sleeve installed in the cylindrical space part of the ceiling slab with a supporter frame at a predetermined distance; forming the primary collector well by placing primary concrete in the rebar frame of the primary collector well and placing secondary concrete in the supporter frame, while installing a supporter with concrete to support the flange of the cylindrical sleeve while surrounding the bottom of the cylindrical sleeve (120) in integration with the ceiling slab of the primary collector well; and installing a secondary collector well above the level of underground water by covering the supporter, which is installed to support the flange of the cylindrical sleeve while surrounding the bottom of the cylindrical sleeve in integration with the ceiling slab of the primary collector well, vertically with the secondary collector well.
