Since the sealing members 77 and 78 come into contact with each other in a pressurized state due to the pressing force caused by the elastic recovery force that the clamping parts 80 and 81 of the clamping member 43a try to approach each other, high water tightness is achieved, and the wall 33 Water generated from cracks and the like is prevented from leaking to the outside when the water led to the recess 60 through the insertion holes 61 and 62 and the water condensed in the recess 60 are leaked to the outside. Generation | occurrence | production of the malfunction that a water drop falls from the water guide apparatus 31 within a certain structure 32 is prevented.
[0038]
Further, the second planar seal member 78 is interposed between the other mounting portion 37a and the region 85 of the water guide plate 42 facing the other mounting portion 37a. The opposing region 85 of the water guide plate 42 is fixed in a state of being tightened toward the other attachment portion 37 b by a screw 86. As a result, the watertightness between the facing region 85 and the other attachment portion 37b is improved, and leakage of water from the water conduit 39 to the outside is prevented.
[0039]
In the above description, the one holding tool 40a has been mainly described. However, the same applies to the other holding tool 40b, and is configured symmetrically when viewed from the side facing the wall surface 33, that is, from below in FIGS.

[0052]
  According to this invention of Claim 2, a clamping memberThe one side end in the width direction of the pair of sandwiching portions is connected by the connecting portion and is orthogonal to the longitudinal directioncross sectionshapeIs formed in a substantially U shape, so that the attachment portion and the water guide plate can be sandwiched across the entire length in the longitudinal direction with a wide width from both sides, thereby reducing the contact area between the attachment portion and the water guide plate. The watertightness can be further improved by increasing the size.
[0053]
  According to the third aspect of the present invention, the clamping member isOne clamping partA flat presser part is formed on theOne clamping partThus, one attachment portion of the holder main body and one side portion in the width direction of the water guide plate are watertightly sandwiched, and the region disposed on the other attachment portion of the water guide plate by the holding portion is It can be pressed toward the mounting part of the water, thereby further improving the water tightness, and leakage of water in the water conduit formed between the wall surface and the water guide plate between each holder body. It can be surely prevented.
[0054]
According to the fourth aspect of the present invention, since the holder has a pair of attachment portions extending in the direction away from each other in the width direction, one end in the width direction of the water receiving plate using the holding member in each attachment portion. It is possible to sandwich and hold the portions, thereby forming a water conduit on both sides of one holding tool, and securing a plurality of rows of water conduits. With respect to the wall surface of a structure such as a tunnel, water generated from the cracks of the wall surface over a wide area can be collected in each water conduit to leak water.
[0055]
According to the fifth aspect of the present invention, since the water guide plate is made of a synthetic resin having translucency, the inside of the water guide channel is visually confirmed through the water guide plate from the outside, and the flow of water in the water guide channel is measured. The state and the presence or absence of clogging can be easily confirmed, and the workability for maintenance management can be facilitated.
