STABILIZATION SYSTEM OF LANDFILL AND CONTAMINATED SOIL WITH HORIZONTAL AND VERTICAL BRANCH PIPES FOR AIR INJECTION AND NOXIOUS GAS EXTRACTION AND STABILIZATION METHOD THEREOF

摘要

PURPOSE: A stabilization system of landfill and contaminated soil with horizontal and vertical branch pipes for air injection and noxious gas extraction is provided to convert anaerobic conditions of contaminated soil into aerobic conditions more effectively and substantially reduce amount of noxious gas exhausted, and a stabilization method thereof is provided. CONSTITUTION: The stabilization system of landfill and contaminated soil with horizontal and vertical branch pipes for air injection and noxious gas extraction comprises an air injection unit(30) for supplying air under a certain pressure; a noxious gas extraction unit(40) for extracting noxious gas existing in contaminated soil; a vertical pipe part(20) comprising a vertical main pipe(21) connected to the air injection unit and the noxious gas extraction unit and horizontally installed on an upper part of contaminated soil, a plurality of vertical branch pipes(24) installed at a certain part of the vertical main pipe and vertically installed in the contaminated soil, and a fixed distributor(60) installed between the vertical main pipe and the vertical branch pipes; and a horizontal pipe part(10) comprising a horizontal main pipe(11) connected to the air injection unit and the noxious gas extraction unit and horizontally formed at one side of the contaminated soil, a plurality of horizontal branch pipes(14) horizontally installed in the contaminated soil with being extended from the horizontal main pipe, and a fixed distributor(60) installed between the horizontal main pipe and the horizontal branch pipes.
