INVERT PIER AND TUNNEL INVERT CONSTRUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an invert pier and a tunnel invert construction method with high construction efficiency.SOLUTION: An invert pier 1 includes a work platform 10 having a casting space S1 for casting invert concrete downward, a front oblique path 20 stretched between the front end of the work platform 10 and the ground, a rear oblique path 30 stretched between the rear end of the work platform 10 and the ground, and a plurality of support legs 40 attached to the lower portion of the work platform 10 to support the work platform 10 away from the ground. The width of the front oblique path 20 is less than half the width of the work platform 10 and the front oblique path 20 can be connected to an arbitrary position in the width direction of the work platform 10.SELECTED DRAWING: Figure 1
