Construction method for the wall water service box and the wall water service box

摘要

The present invention relates to a method for constructing a wall-open type openable watertight container and an openable watertight container with a built-in wall by which the wall and the open watertight container are installed so as to protrude by a preset thickness, Burying a body formed with coupling connectors into the inside of the wall so that the double pipe pipes are penetrated in the left and right directions; And an extension housing having a third opening communicating with the first opening is formed on a front surface of the main body so as to extend in a length corresponding to the thickness of the counter, ; Engaging the inner cover with the extension housing, the inner cover having a size smaller than the third opening to partially shield the third opening and having a fourth opening communicating with the third opening; And joining the finishing cover having the tubular valve coupling hole to which the tubular valve is coupled so that the double pipe conduits can be connected to the tubular valve, with the inner cover to shield the fourth opening.
