Note that the same components as in the first embodiment are given the same reference numerals.
［作用］
第１の実施例のシール材１が第８図及び第９図
に示す導水管１２の継目１３に使用される場合、
まず第３図に示す如くシール材１が一方の端面２
に嵌着されたのち他方の平板状の端面２ａが第３
図に示す如くリツプ部５に圧接して継目１３のシ
ールが行われる。[Function] When the sealing material 1 of the first embodiment is used for the joint 13 of the water conduit pipe 12 shown in FIGS. 8 and 9,
First, as shown in FIG.
After the other flat end surface 2a is fitted into the third
As shown in the figure, the seam 13 is sealed by pressing against the lip portion 5.
この時、リツプ部５がその両側端縁８，８付近
においてそれぞれ小突起７，７に圧接し、中空部
Ｖ，V1を形成する。また、導水管１２内の流水
Ｗは透孔９を通り中空部Ｖ内に入り、一方導水管
１２の外部の地面Ｅ下の水W1も同様に中空部V1
内に入る。そして、中空部Ｖ，V1内の水Ｗ，W1
はそれぞれリツプ部５に対し水圧を及ぼすため端
面２ａに対する面圧を高めることが出来、更に各
水Ｗ，W1の圧力が高い程止水機能が向上するこ
とになる。 At this time, the lip portion 5 comes into pressure contact with the small protrusions 7, 7 near both side edges 8, 8, respectively, forming hollow portions V, V1 . Furthermore, the flowing water W in the water pipe 12 passes through the through hole 9 and enters the hollow part V, while the water W 1 under the ground E outside the water pipe 12 also flows into the hollow part V 1 .
Go inside. And water W, W 1 in the hollow part V, V 1
exerts water pressure on the lip portion 5, so that the surface pressure on the end face 2a can be increased, and the higher the pressure of each water W, W1, the better the water stop function.
第２の実施例（第５図図示）のシール材１ａが
使用された場合は、スポンジゴム層１０の存在に
より第１の実施例のシール材１の如くソリツドゴ
ム製のリツプ部５の場合と異なり、圧接される端
面２ａの凹凸を十分吸収出来てシール性能の一層
の向上を期待出来る。 When the sealing material 1a of the second embodiment (shown in FIG. 5) is used, due to the presence of the sponge rubber layer 10, the sealing material 1a of the first embodiment differs from the case where the lip portion 5 is made of solid rubber like the sealing material 1 of the first embodiment. , it is possible to sufficiently absorb the unevenness of the end face 2a to be pressed, and further improvement in sealing performance can be expected.
第３の実施例（第６図及び第７図図示）のシー
ル材１ｂの場合は第１の実施例の透孔９が切欠孔
１１に代つただけであるからその作用、効果共に
第１の実施例のシール材１と略同様である。 In the case of the sealing material 1b of the third embodiment (shown in FIGS. 6 and 7), the through hole 9 of the first embodiment is simply replaced with a cutout hole 11, so its function and effect are similar to those of the first embodiment. It is substantially the same as the sealing material 1 of the embodiment.
［考案の効果］
この考案によれば、シール材１，１ａ，１ｂに
設けられた略Ｙ形のリツプ部５がその背面にかか
る水Ｗ，W1の圧力により導水管１２の他方の平
板状の端面２ａに強く密接することが出来るため
従来の長方形断面のシール材に比べて著しく止水
効果を高め得るという特長がある。[Effects of the invention] According to this invention, the approximately Y-shaped lip portion 5 provided on the sealing materials 1, 1a, 1b breaks down from the other flat plate shape of the water conduit 12 due to the pressure of the water W, W1 applied to the back surface thereof. Since it can be brought into close contact with the end surface 2a of the sealing material, it has the advantage of significantly increasing the water-stopping effect compared to conventional sealing materials having a rectangular cross section.
また、基部４、リツプ部５、小突起７が断面形
状において左右対称に形成されているので、いず
れのリツプを導水管内の水、導水管外の水に臨ま
せるかを考慮する必要がないので、取付作業を容
易迅速に行うことが出来る。 Furthermore, since the base portion 4, lip portion 5, and small protrusion 7 are formed symmetrically in cross-section, there is no need to consider which lip should face the water inside the water pipe or the water outside the water pipe. , the installation work can be done easily and quickly.
