Work space forming for wall repair and work space forming method for wall repair

摘要

PROBLEM TO BE SOLVED: To provide a workspace formation for repairing a wall surface which makes it possible to safely and efficiently repair damages on underwater walls such as concrete quay walls and breakwaters, and a workspace formation method for repairing a wall surface.SOLUTION: A horizontally elongated front closing panel 2 is installed on a seabed 51 with a gap serving as a working space S between a repair wall surface 52A of a concrete breakwater 52 constructed on the seabed ground 51. Side closing panels 6, 6 are provided at both longitudinal ends of the front closing panel 2. The side closing panel 6 defines the working space S in a water-impermeable state by bringing distal end faces of a large number of closing members 9 into contact with the repair wall face 52A. A concrete plate 11 serving as a weight is stored in a weight storage portion 4 of the front closing panel 2 and weight is given to the front closing panel 2 to ensure stability in water.SELECTED DRAWING: Figure 1
