2, the module-type water leakage induction apparatus according to a specific embodiment of the present invention includes a panel unit 100 for collecting water leaking from the joint portion provided on an inner circumferential surface of a structure so as to cover a joint occurring between structures, And a fixing member 200 fixed to the concrete structure 10 so that one side thereof is fixed on the concrete structure 10 and the other side is protruded outward to fix the panel unit 100 to the concrete structure 10 .

As shown in FIG. 3, the panel unit 100 is formed in a channel shape having an open side that contacts with the concrete structure 10, and is extended outward from the side surface so as to be in close contact with the concrete structure 10 A supporting portion 113 is formed.

3, the panel unit 100 includes a rectangular panel 110 covering the top and side surfaces of the inner circumferential surface of the structure, and a saw-type panel 130 connecting the rectangular panels 110 installed at right angles to each other. And a connection panel 120 coupled to connect the straight type panels 110 adjacent to each other.

Here, the linear panel 110 is formed in a longitudinal direction, and the horn panel 130 is formed in a bent shape to cover a hatch portion.

As shown in FIG. 4, a fixing part 111, which protrudes on the concrete structure 10 and is fastened to the fixing member 200, is provided on the inner side surface of the flat panel 110.

8, the coupling protrusion 114 of the straight panel 110 fixed by the fixing member 200 fixed to the concrete structure 10 is inserted into the connection panel 120, Through-holes (124) of the flat panel (120) are inserted and coupled to the flat panel (110).

Accordingly, the module-type water leakage induction apparatus according to the specific embodiment of the present invention has an effect that the panel unit 100 can be easily attached and detached, thereby increasing the workability.

On the other hand, in the concrete embodiment of the present invention, there is a possibility that the panel unit 100 may be damaged when water leaking from the joint part of the concrete structure 10 freezes during a winter temperature drop.

Accordingly, in another embodiment of the present invention, the panel unit 100 can be configured to prevent frost damage by freezing.
