Foundation structure of waste landfill site and construction method thereof

摘要

The present invention is a waste landfill foundation structure capable of shortening construction time and reducing construction costs by utilizing a water-order wall continuously arranged in the ground as a foundation for a roof structure in a waste landfill in which a roof structure having a pulling force acting on the foundation is installed, such as an air dome roof, and its It is about the construction method. The foundation structure of the waste landfill site of the present invention is a vertical order wall foundation that is a vertically ordered wall that is continuously arranged in the ground along the outer periphery of the landfill, and is composed of a slurry wall, which is an underground continuous wall, and vertical and horizontal reinforcing bars are arranged therein to serve as a foundation; A plurality of base plates installed to be spaced apart from each other on the upper surface of the vertical order wall base, and fixed to the upper end of the vertical order wall base by a fixing bar protruding from the lower part; A pull-out resistance pile provided inside the vertical order wall base and having an upper end coupled to the base plate; A roof structure in which a lower end is fixedly installed on an upper portion of the base plate; And a guide wall that is permanently retained on the inside and outside of the upper end of the vertical order wall base, and reinforces the shear force of the upper part of the vertical order wall base by reinforcing the reinforcement therein so that the entire body moves. It characterized in that it consists of.
