良好な水密構造が形成され、止水性の非常に高い
ものである。 According to this water-stop structure at the driving part of the fixing member 8, the lower and upper adhesive layers 3 and 5 are in close contact with the peripheral wall 8a of the fixing member 8 due to the adhesive action of the adhesive, and the head of the fixing member 8 is The upper adhesive layer 5 is tightly coated on the back surface of 8b to form a watertight structure. Therefore, even if spring water from the primary lining concrete 7 side travels through the peripheral wall 8a from the tip side of the fixing member 8, the adhesives 3 and 5 adhere to the peripheral wall of the fixing member 8, forming a watertight structure. This prevents leakage from the head 8b side of the fixing member 8, and even if the shaft portion 8c of the fixing member 8 is driven in, the peripheral wall 8
Even if there is a slight gap between a and the adhesive layers 3 and 5 and spring water permeates through this gap, the back surface of the head 8b of the fixing member 8 will be tightly covered with the adhesive layer 5, Since there are no gaps where water can leak, a complete water-stopping effect is achieved. That is, in the water-stopping structure shown in FIG. 4, the adhesive layers 3 and 5 are formed above and below the washer body 4, respectively, so that the water-tightness is more reliable.
Further, as shown in FIG. 4, the head 8b of the fixing member 8
Fixing member 8 until the back side is in close contact with upper adhesive layer 5
By driving in, a good watertight structure is formed also on the back surface of the head 8b, and the watertightness is extremely high.

の固定状態が維持される。 Further, in the water stop structure described above, an upper adhesive layer 5 is formed covering the washer body 4, and this upper adhesive layer 5
Since the fixing member 8 is driven in, the fixing member 8 can be driven in very easily. In other words, when the fixing member is driven into the washer with the washer facing upward, when the tip of the fixing member is brought into contact with the washer to position it, the tip of the fixing member slides over the washer and is difficult to position. On the other hand, when the tip of the fixing member 8 is placed on the surface of the adhesive layer 5, it does not slip and positioning is very easy.
All you have to do is hit it and type in as is.
The work of driving the fixing member 8 is easily performed. Moreover, in the water stop structure described above, the washer body 4 is a mere disc-shaped and the fixing member 8 is configured to punch out this washer body 4. There is no need to worry about positioning the fixing member 8 according to the hole, and the tip of the fixing member 8 can be simply placed on an appropriate position on the upper adhesive layer 5 and driven. From this point of view, the work of placing the fixing member 8 is also simplified. It is easy to make, and when the fixing member 8 punches out the washer body 4, a through hole 9 is formed, and the diameter of this hole 9 is the same as the diameter of the driving shaft portion 8c of the fixing member 8. Therefore, since the movement of the washer body 4 is regulated by the driving shaft portion 8c of the fixing member 8, the waterproof sheet 1 can be secured by the fixing member 8 reliably.
remains fixed.

This water stop structure also has the same effect as the embodiment shown in FIG. In this case, as shown by the dashed line,
After the fixing member 8 is driven in, an adhesive layer 10 can be formed to cover the head 8b of the fixing member 8, thereby making it possible to further improve the water-stopping effect. Further, after the fixing member is cast, a heat-fusible substance can be supplied near the head of the fixing member that protrudes from the upper adhesive layer.

逸脱しない範囲で種々変更して差支えない。 Furthermore, in the above embodiment, the fixing member was driven in after removing the release layer 6, but in some cases, the fixing member could be driven in without removing the release layer 6, and a ring-shaped washer with a through hole could be used as the washer. Various changes may be made to other configurations without departing from the gist of the present invention.

作業が簡単である。 As explained above, when fixing a waterproof sheet by driving a fixing member into a predetermined installation location, the fixing member can be fixed by driving the shaft of the fixing member until the back surface of the head is tightly covered with the adhesive layer. A completely watertight structure is formed on the back surface of the head of the fixing member, and therefore, water is reliably prevented from leaking from the head side of the fixing member to the outside through the peripheral wall of the fixing member. Further, according to the water stop structure of the present invention, when driving the fixing member, the tip of the shaft portion can be easily positioned, and the operation of driving the fixing member is simple.
