Beschreibung
Zusammenfassung:	The present invention discloses a box type duct with circumferential obtuse angle connection. Unit plates respectively located on the upper, lower and two side surfaces are spliced in the circumferential direction to form a unit pipe section, and the unit pipe sections are spliced in the axial direction to form a box type duct; wherein the unit plate is an arc-shaped corrugated plate arched to the outside of the box type duct, and the adjacent unit plates form an obtuse angle of circumferential connection. The cross section of the duct is in an approximately rectangular box shape, so the utilization ratio of clearance of the duct is high; the unit plate adopts an arc-shaped structure, and by utilizing the pipe-soil joint stressing principle, the strength and bearing capacity of the overall structure are maximized; and the box type duct adopts flat flange or angle steel flange connection in the circumferential direction, so the overall construction progress is greatly accelerated.
