Therefore, the guide members 21 and 21 are arranged symmetrically with respect to the clockwise direction of the bolt 13 via the bolt 13 in a state of being located on the rear side of the engaging member 14.

Further, the tip portions of the guide members 21 and 21 are permeable to water even when the engaging member 14 is in contact with the stopper member 15 in a state where the cover body 6 is fitted to the surface side opening of the water permeable hole 3. It is formed to a length that is inserted into the hole 3.

Next, a method of attaching the water permeable hole cover 5 will be described.

First, if necessary, the cover body 6 is cut according to the length of the water permeable hole 3, and the required number of attachments 7, 7, that is, the bolt support member 12, is inserted into the slide groove 11 according to the length. Then, both locking pieces 9 and 9 are supported by the bolt support member 12.

At that time, the engaging member 14 is rotated relative to the bolt 13 to move the engaging member 14 toward the tip end side of the bolt 13, and the engaging member 14 is set so as to be parallel to the cover body 6. ..

Next, as shown in FIG. 6A, the bolt support member 12 is slid in the slide groove 11 so as to be aligned with the positions of the arbitrary intake holes 10, 10 ... (Mounting holes), and this state is set. The attachment 7 is inserted into the water permeable hole 3, and the cover body 6 is fitted into the opening of the water permeable hole 3.

Next, a hexagon wrench is inserted into the hexagonal hole on the head of the bolt 13 from the water intake holes 10, 10 ... (Mounting holes) of the cover body 6 and rotated in a predetermined direction (clockwise when viewed from the top surface). As shown in FIG. 6B, the rotational torque of the bolt 13 is transmitted to the engaging member 14, and the engaging member 14 rotates clockwise in conjunction with the rotation of the bolt 13.

Then, with the rotation of the engaging member 14, the guide members 21 and 21 move toward the front in the rotation direction of the bolt 13, and both ends of the engaging portion main body 20 are below the waterway side opening edge of the water permeation hole 3. Protrude.

Further, due to the rotation of the engaging member 14, the edge portion of the guide members 21 and 21 far from the central axis of the bolt 13 is pressed against the inner surface of the water permeable hole 3, and the rotation of the engaging member 14 is restricted at that position. In that state, the engaging member 14 moves upward, that is, toward the bolt support member 12.

In this state, when the bolt 13 is further rotated, the engaging member 14 is gradually moved upward while being guided by the guide members 21 and 21 while the guide members 21 and 21 are pressed against the inner side surface of the water permeable hole 3. At a predetermined position, both ends of the engaging portion main body 20 engage with the waterway side opening edge of the water permeation hole 3.

Then, when the bolt 13 is rotated and tightened, a downward force is applied to the bolt support member 12 by the bolt head 13a in conjunction with the rotation, and the pressing portions 19 and 19 of the bolt support member 12 are inclined plates of the locking pieces 9 and 9. The portion is pressed so that the inclined plate portion is brought into contact with the chamfered portion 4 formed at the opening edge portion of the water permeation hole 3, and the cover body 6 is fitted in a wedge shape to the opening edge portion of the water permeation hole 3.

Therefore, in the water permeable hole cover 5, both ends of the locking portion main body 20 screwed to the lower side of the bolt 13 are locked to the waterway side opening edge of the water permeable hole 3, and the locking member 14, the bolt 13, and the bolt are engaged. Since the cover body 6 connected via the support member 12 is fitted to the surface side opening edge portion, it is fixed to the water permeation hole 3.

On the other hand, in order to remove the water permeable hole 3 cover, as shown in FIG. 7D, the cover is rotated in the direction opposite to that at the time of mounting (counterclockwise when viewed from the upper surface).

When the bolt 13 is rotated counterclockwise, as shown in FIG. 7 (e), the engaging member 14 moves to the stopper member 15 side, and the engaging member 14 main body becomes the water channel side opening edge of the water permeation hole 3. The engaging member 14 rotates counterclockwise in response to the rotational torque of the bolt 13, and the guide members 21 and 21 are released from the state of being pressed against the inner surface of the water permeable hole 3. NS.

In this state, the tip portions of the guide members 21 and 21 are in a state of being inserted inside the water permeable hole 3, and the outer surface of the guide members 21 and 21 is the inner surface on the opposite side to the time when the water permeable hole 3 is attached. Therefore, the counterclockwise rotation of the engaging member 14 above a certain level is restricted.

Then, as the rotation of the bolt 13 is advanced, the engaging member 14 comes into contact with the stopper member 15 and stops, so that the cover body 6 is pulled up in this state.

When the cover body 6 is pulled up, as shown in FIG. 7 (f), the width of the water permeable hole 3 narrows toward the upper side, so that the guide members 21 and 21 in contact with the inner side surface are pushed to the inner side surface and engaged. Guide the mating member 14 so that it is substantially parallel to the water permeable hole 3 cover.

Therefore, the water permeable cover 5 can be easily pulled up without the attachments 7 and 7 getting caught in the water permeable holes 3.

In the above-mentioned embodiment, an example in which the engaging member 14 is integrally formed with a metal plate material such as a stainless steel material has been described, but the present invention is not limited to the above-mentioned example, and for example, the guide members 21 and 21 are pin-shaped members. May be formed by.
